Full textAbstract:
In the warm humid tropical climate of Bali, Indonesia, overheating and high humidity influence occupants' comfort, indoor climate and the comfort of their homes, both directly and indirectly. The traditional way to deal with these problems, using natural ventilation, was ecologically sound and acceptable. However, development of tourism in Bali has had a positive impact on people's earning, causing cultural pressure, migration and a rapid rise in the urban population, as well as increasing housing demand. In urban areas, the methods of climate modification have moved away from natural ventilation, and comfort is now more often achieved by installing air conditioning. This has caused increasing energy use and had economic impact. As world-wide energy consumption will continue to increase, the use of more energy will have more impact on global warming. In these circumstances, energy efficiency is paramount, particularly in the dwelling designs for new housing development in Indonesia. The study focuses on the design of a thermally comfortable dwelling in the warm humid climate of Bali, Indonesia, with emphasis on the energy efficiency of the naturally ventilated and air-conditioned dwelling. Using a computer program and energy conservation strategies, a dwelling design was simulated. A model dwelling was adopted from a standard house type for people on a middle class income, based on the family size of a couple with two children. Such units are built by the National Housing Authority of Indonesia. A comprehensive study of the computer-simulation outcomes, survey research, previous works undertaken and literature reviews were carried out, to develop a thermally comfortable dwelling design. This new thermally efficient dwelling design was simulated to draw the final conclusions of the research. The research discovered that the combination of both natural ventilation and air conditioning, integrated with the combined design of a compound-compact dwelling, are an intelligent response to the thermal comfort performance problems of a dwelling in the warm humid climate and architecturally adaptable to the culture of Bali. The study found that a combination of natural ventilation with air conditioning which is only used when necessary, coupled with insulation and shading devices, can significantly reduce energy consumption and achieve adequate thermal comfort. In this respect, however, architectural design should come first, and be considered before an engineering solution. The reasons are that architectural solutions are more robust, and has a long duration of applicability, while the technology is perhaps the opposite, being prone to mechanical failure. When a less compact dwelling is designed, increased use of natural ventilation can be achieved. The use of airtight construction, insulation in the building envelope and shading devices are effective ways of reducing the air-conditioning load.

Full textAbstract:
Earth’s climate system has experienced significant changes throughout its history. Tropical, glacial and interglacial conditions have persisted across the globe during the Tertiary, and the present interglacial period with strong seasonality and episodes of warming and cooling has existed for the last several thousand years. However, rapid warming during the last century has highlighted the importance of understanding past climate behaviour, in order to predict the likely effects of such warming on our future climate. This has led to the use of proxies, such as sediment cores, tree rings, ice and carbonates, which provide high resolution palaeoclimate archives. Studies using a variety of proxies from around the globe have developed a network of site specific climate information, offering insights of climate fluctuations on a millennial scale, and identifying changing oceanic conditions as a major influence on global climate change. Coral skeletons are particularly sensitive recorders of ambient seawater conditions as they record fluctuations of oxygen and carbon in their aragonitic skeletons, which are caused by perturbations of sea surface temperature (SST) and sea surface salinity (SSS). Therefore, tropical oceans themselves provide a crucial record of climate change. Many of the coupled atmospheric-oceanographic processes that drive the global climate system occur in the Indo-Pacific, making it a particularly important region for data collection. Porites corals from the Indo-Pacific have been studied in detail and have revealed high resolution SST and SSS records, yet comprehensive investigations using other coral species are minimal. This study expands upon the current understanding of coral proxies by investigating three coral species of different ages, and provides new insights into the palaeoclimate history of the Indo-Pacific.
Goniastrea retiformis, Platygyra pini and Platygyra lamellina corals have been retrieved from Timor Leste in the Indo-Pacific, and analysed using stable and radiogenic isotopic techniques. Sclerochronology was used to determine that the 4.5 year old, modern G. retiformis coral was living from 2006-mid 2010. Uranium-thorium (U/Th) analysis provided a mid Holocene age of 4.5 ± 0.092 (2σ) ka for the fossil P. pini. Uranium-lead (U/Pb) techniques were used to obtain a 2.7 ± 0.34 (2σ) Ma age for the fossil P. lamellina. A rigorous diagenetic screening process of X-ray diffraction (XRD), petrographic analysis of thin sections, and scanning electron microscopy (SEM) has been carried out to ascertain the extent of preservation in each coral. X-ray images allow annual density bands to be located and unique micromilling paths were developed for the three samples. This enabled us to obtain the first δ¹⁸O and δ¹³C stable isotope results for a G. retiformis coral, and the first fossil coral results for the Platygyra genus. Cross spectral analysis has been used to verify the periodicity of seasonal fluctuations visible in the data, and confirmed that these coral species are suitable for use as climate proxies.
G. retiformis is an abundant reef coral distributed throughout the tropical Pacific, and has a robust skeletal configuration making it suitable for use as a climate proxy. The 4.5 year long record has revealed that δ¹⁸O and δ¹³C values range from -4.62‰ ± 0.03‰ (2σ) to -6.11‰ ± 0.02‰ (2σ), and 1.57‰ to -2.53‰, with means of -5.35‰ and -1.02‰, respectively. These values are in agreement with the average δ¹⁸O range of -5.1 to -5.6‰ in modern corals throughout the Indo-Pacific, predominantly of the Porites genus. Statistical analysis of the isotopic data has revealed a quasi-biennial signal in G. retiformis, typical of the temporal interaction between El Niño Southern Oscillation (ENSO) and the South Asian monsoon. Results have also been compared to the Southern Oscillation Index (SOI) in order to assess potential relationships between coral isotopes and ENSO. This has shown an accurate record of El Niño and La Niña events for the first half of the ~ 4.5 year record, from 2006 to mid 2008. Climate processes such as local rainfall and the Indian Ocean Dipole (IOD) are also reflected in the record, to varying extents.
The use of Platygyra corals as climate proxies is limited to three investigations using modern samples, despite the fact that this genus has a much broader latitudinal range than the extensively studied Porites genus. This thesis provides the first examination of fossil samples, and provides analysis of both pristine and altered specimens. The 4.5 ka P. pini coral has allowed investigation of the palaeoclimate record in a sample that has been exposed to diagenesis. XRD, petrographic and SEM analyses have revealed widespread secondary aragonite growth, dissolution and secondary calcite within the coral, which would have occurred due to marine and freshwater diagenesis. However, primary growth textures have been retained in some areas of the coral. δ¹⁸O and δ¹³C values range from -3.47‰ ± 0.03‰ (2σ) to -5.45‰ ± 0.02‰ (2σ), and 3.43‰ to -0.49‰, with means of -4.82‰ and 1.12‰, respectively. These values are significantly more positive that the mean δ¹⁸O of four Platygyra corals from the Pacific region, which range from -4.82‰ to -5.10‰. There are two reasonable explanations for this. Secondary aragonite, which is detected throughout the milled section of coral, causes positive shifts in coral δ¹⁸O, an effect which is likely to have altered the geochemical record of this particular coral. But the fact that SST in the southern Indo Pacific Warm Pool (IPWP) during the mid Holocene were 1.2° C cooler than present must also be acknowledged, as cooler temperatures also impart a shift toward higher δ¹⁸O, due to equilibrium fractionation processes. SST reconstruction using the temperature dependence equation from a modern Platygyra coral reveals an SST range of 18.5-27.6° C, and mean of 24.7° C. The present day mean annual SST of 28° C suggests that mid Holocene temperatures less than 26.8° C are unrealistically cool, highlighting the fact that isotopic fractionation during diagenesis has affected coral chemistry. However, the presence of interannual periodicity indicates that ENSO was operating, and the magnitude of isotopic fluctuation through the 10 year record is similar to that found in modern and other Holocene corals. We suggest that although absolute isotopic and SST values are unreliable, prohibiting the extraction of high resolution climate records, insights into the behaviour of broad scale, seasonal and interannual climate processes may still be obtained.
A strong annual periodicity has been detected when analysing the stable isotopic values recorded in the 2.7 Ma P. lamellina coral. This indicates that seasonal SST fluctuations were the dominant influence on this coral. Ranges of -4.67‰ ± 0.03‰ (2σ) to -5.48‰ ± 0.02‰ (2σ) and 0.88‰ to -1.12‰ for δ¹⁸O and δ¹³C, respectively, are similar to modern Platygyra coral results, suggesting that this coral has been preserved in pristine condition. Palaeo-SSTs have been reconstructed using a modern Platygyra temperature dependence equation, providing a range of 24-27.7° C and a mean of 25.9° C. Foraminiferal data from sediment cores in the greater Indo-Pacific suggest that mean annual SSTs at this time were ~ 2-3° C cooler than present. The coral record I present supports this statement, providing new insights into our understanding of tropical palaeoclimates. This coral has been entrained within a turbidite deposit on the sea floor that has subsequently been uplifted during the emergence of Timor, with U/Pb dating allowing further constraints of the stratigraphic age of the deposit. Tectonic narrowing is postulated to have caused major changes to the Indonesian Throughflow (ITF) from 4-2 Ma, and been a driver of major global climate change beginning in the late Pliocene. This means that fossil Platygyra corals Timor Leste could provide unique time slices of information about this important time in global climate history.
This study confirms that G. retiformis, P. pini and P. lamellina corals are excellent candidates for further, detailed investigations. They provide the opportunity to develop new coral proxies which are both abundant throughout the tropics and distributed over a wide latitudinal range. Their prevalence in both modern and fossil reefs means that once modern samples of each species have been calibrated against modern SST and SSS, these corals will provide reliable, quantitative palaeoclimate proxies, with potential for data capture throughout the Indo-Pacific and mid latitudes. Geochemical coral archives are a crucial tool in the study of climate processes, and we believe that these species are ideally suited to enhancing and refining our current understanding of earth’s climate system.

Full textAbstract:
Over the past century, glaciers throughout the tropics have predominately retreated.
These small glaciers, which respond quickly to climate changes, are becoming
increasingly important in understanding glacier-climate interactions. The glaciers on Mt.
Jaya in Irian Jaya, Indonesia are the last remaining tropical glaciers in the Western
Pacific region. Although considerable research exists investigating the climatic factors
most affecting tropical glacier mass balance, extensive research on the Mt. Jaya glaciers
has been lacking since the early 1970s.
Using IKONOS satellite images, the ice extents of the Mt. Jaya glaciers in 2000,
2002, 2003, 2004, and 2005 were mapped. The mapping indicates that the recessional
trend which began in the mid-19th century has continued. Between 1972 (Allison, 1974;
Allison and Peterson, 1976) and 2000, the glaciers lost approximately 67.6% of their
area, representing a reduction in surface ice area from 7.2 km2 to 2.35 km2. From 2000
to 2005, the glaciers lost an additional 0.54 km2, representing approximately 24% of the
2000 area. Rates of ice loss, calculated from area measurements for the Mt. Jaya glaciers
in 1942, 1972, 1987, and 2005, indicate that ice loss on Mt. Jaya has increased during
each subsequent period. Preliminary modeling, using 600 hPa atmospheric temperature, specific humidity,
wind speeds, surface precipitation, and radiation values, acquired from the NCEP
Reanalysis dataset, indicates that the only climate variable having a statistically-significant
change with a magnitude great enough to strongly affect ice loss on these
glaciers was an increase in the mean monthly atmospheric temperature of 0.24ðC
between 1972 and 1987. However, accelerated ice loss occurring from 1988-2005
without large observed changes in the weather variables indicates that a more complex
explanation may be required. Small, though statistically-significant changes were found
in regional precipitation, with precipitation decreasing from 1972-1987 and increasing
from 1988-2005. While, individually, these changes were not of sufficient magnitude to
have greatly affected ice loss on these glaciers, increased precipitation along with a
rising freezing level may have resulted in a greater proportion of the glacier surface
being affected by rain. This may account for the increased recession rate observed in the
latter period.

Full textAbstract:
A policy mechanism known as REDD+ (‘Reducing Emissions from Deforestation and forest Degradation, and enhancing forest carbon stocks and conservation’) is designed to contribute to climate change mitigation efforts and simultaneously support developing countries’ national development agendas. This is effected by providing REDD+ host countries with financial incentives to produce measurable reductions in carbon emissions beyond what would have occurred without REDD+. Indonesia is a key target of the REDD+ mechanism for several reasons, eg: (i) its forests support 10% of the world's remaining tropical rain forests and represent the fourth largest forest carbon stock globally, (ii) 80% of its GHG emissions result from deforestation and forest degradation, and (iii) it has the potential to reduce up to 120 million tons of CO2 per year. Consequently, to date Indonesia has received donor’s commitments of nearly US$2 billion for REDD+ development. Given this profile, Indonesia’s success in implementing REDD+ can contribute significantly to the efficacy of REDD+ globally. However, achieving this potential is undermined by a set of long-standing problems inherent within Indonesia’s forest institutions, including issues of corruption, coordination, uncertainty in the forests’ legal system, capacity to manage forests at multiple levels of government, and the use of forest concessions to consolidate political power. This thesis asks the primary research question: “How do REDD+ institutions effect governance reform within Indonesia’s existing national and sub-national forest institutions?” 'Institutionalism', in particular the concept of 'institutional interplay' is the main conceptual framework deployed and grounded in the context of the vertical interplay between the internationally-formulated REDD+ mechanism and Indonesia's forest institutions. Guided by the themes that emerged from the data collected, this research explored and expanded certain analytical approaches within the perspectives of institutionalism and governance, namely ‘historical institutionalism’, ‘clientelism’, 'critical juncture', ‘policy networks’ and ‘social learning’. This thesis adopted the ‘four paper route’ and employed mixed methods of data collection (ie interview, shadowing, and policy document review). It found that during the process of institutional interplay as REDD+ institutions deployed the principles of good governance, advanced a robust system of measurement, reporting and verification of reductions in carbon emission, attracted large funding, and involved a broad range and multi-scale of actors, the REDD+ mechanism produced 'collateral benefits'. The tangible form of these benefits was the production of new policy instruments, eg the 'national REDD+ strategy' (paper 2), 'one map initiative' (paper 3), and ‘village agreement’ (paper 4) through which a significant body of evidence showed the capability of REDD+ to effect governance reform within and beyond Indonesia's forestry sector. Paper 1, revealed how policy actors perceived REDD+ and as such provides the basis of these three papers. The positive results of institutional interplay that occurred were determined not only by the characteristic of REDD+ institutions themselves but also by the existence of domestic reformists and the national reform agenda.

Full textAbstract:
The IPCC's report in 2018 projects global warming will increase by 1.5oC in 2030, which makes contribution of each country to control their emissions becomes significant. This study seeks to investigate what entitlement human beings have over the absorptive capacity of the atmosphere as well as the harm it caused by elaborating the Entitlement Theory of Justice, thereto, finding out how the burden of climate change should be distributed according to the Polluter Pays Principle (PPP) and the Equal per Capita Shares Principle (ECSP). Furthermore, this study seeks to investigate Indonesia's part in increasing the burden of climate change and whether Indonesia should be held responsible for its part by comparing data of Indonesia's emissions to some developed countries' emissions. Humanity has a collective ownership over the absorptive capacity of the atmosphere, which implies that every individual has equal share of this absorptive capacity. A violation of this equal share should be compensated. The PPP suggests countries, who has the most cumulative amount of emissions from the past to present, to compensate and bear the climate change burden. While, the ECSP suggests countries, who emit more than their equal share per capita, to bear the climate change burden and reduce their emissions. Indonesia, despites massive amounts of CO2 released by its deforestation and annual haze, contributes insignificant to climate change due to both its cumulative and per capita emissions are considerably low compared to developed countries and even lower than acountry with large population size such as China.

Die vorliegende Studie analysiert die Politische Ökonomie von Forstplantagen in den Tropen. Die Analyse der Makroebene zeigt dabei eine globale Perspektive auf, sowie historische Veränderungen von Paradigmen in Bezug zu Waldplantagen. Der zweite Teil der Studie analysierte Plantagen auf der Mikro-Ebene im Hinblick auf divergente geographischen Zusammenhänge, nämlich Paraguay und Indonesien. Fallstudien eignen sich hierbei, um ein vielfältiges Spektrum von Waldplantagen darzustellen, sowie Beispiele für die in der Makroebene abgeleiteten Paradigmen zu illustrieren. Abschließend verbindet die Studie die Entwicklungen der Makro-Ebene mit Belegen aus der Mikro-Analyse. Hierauf ableitend werden Empfehlungen für die Anlage zukünftiger Plantagen getätigt.
Die Methodik wurde den Untersuchungsebenen in einem iterativen Prozess angepasst. Der Umfang variiert dabei von Makro- bis Mikroanalysen, sowie vom theoretischen bis zum empirischen Niveau. Auf der Makroebene wurde eine Politische-Ökonomie-Analyse und eine Untersuchung desrelevanten historischen Materials durchgeführt. Weiterhin wurden Plantagen Paradigmen anhand ausgewählter Indikatoren abgegrenzt. Für die Mikroebene wurden Fallstudien mit lokalen Interviews durchgeführt, welche Daten für eine Mehrkriterienanalyse (MCA) lieferten. Die Kombination der Mikro- und Makroanalyse erfolgte durch eine Korrelationsanalyse und wurde durch eine Diskussion abgerundet.
Das Forschungsergebnis aus der globalen Analyse ist eine Typologie von sechs Paradigmen und deren Untervarianten, welche als theoretisches und analytisches Werkzeug in der Forschung zu Plantagen dienen können. Die Paradigmen wurden klassifiziert als: i) das vorindustrielle P.; ii) das kolonial industrielle und national industrielle; iii) das Schutzparadigma; iv) das soziale P.; v) das neo-liberale und modifiziert neoliberale P. und vi) das globalpolitische Paradigma.
Die Ergebnisse der Fallstudien und MCA zeigen zum einen sichtbare Mängel in Plantagen unter verschiedenen Paradigmen auf und unterstreichen zum anderen positive Effekte bestimmter Paradigmen. Die MCA Bewertungspunkte zeigen zum Beispiel, dass manche Paradigmen mit dem Kriterium Landkonflikt korrelieren, oder präsentieren unterschiedliche lokale Beteiligung auf verschiedenen Plantagen, illustrieren Vorteile, die Plantagen für unterschiedliche Interessengruppen bringen. Die MCA bewertet weiter die Wirtschaftsleistung der Plantagen und vergleicht Faktoren, wie Nutzenverteilung, Rentabilität, Marktzugang und Rahmenbedingungen für Investitionen. Sie analysiert soziale Faktoren, wie Arbeitssicherheit, Zugang zu Dienstleistungen, Beteiligung oder Personalmanagement. Weiterhin werden Umweltprobleme durch die Studie aufgegriffen, z.B. Landnutzungsänderungen, Wasser- oder Boden- Auswirkungen, Lebensraumfunktion usw.
Wie die vergleichende Analyse zeigt, ist die modifizierte Neoliberale Paradigma Plantage (Outgrower-Scheme) besonders geeignet, um sowohl soziale als auch wirtschaftliche Vorteile zu sichern (90 % und 84 % in den entsprechenden Feldern gegenüber dem hypothetischen Idealtyp Plantage). Andere Forschungsergebnisse deuten auf wichtige Erkenntnisse bei der Plantagenentwicklung hin, die auf der Plantagen-Ebene und bei der Gestaltung nationaler Rahmenbedingungen für den Plantagensektor berücksichtigt werden sollten. Handlungsempfehlungen für die forstwirtschaftliche, epistemische Gemeinschaft zur Gestaltung der weiteren Diskurse in Bezug auf globalen Plantagen werden ebenfalls diskutiert.

Full textAbstract:
Lack of urgency regarding climate change adaptation has caused limited actions to be applied in public asset management in Indonesia. In addition, the costs associated with adaptation of assets can be high in some cases. However, these costs will likely be even higher in the long-term, if responses are delayed. Furthermore, studies suggest adaptation to climate change will enable public assets to adjust to future changes, minimise negative impacts, take advantage of new opportunities and maintain sustainable services. Research in response to climate change, in assets or infrastructure in general, and public assets in particular, has been conducted in several developed countries, such as Australia and the United Kingdom. However, climate change adaptation (CCA) research related to public asset management (PAM) is considered lacking in Indonesia. This research aims to develop a framework for CCA for incorporation in PAM and apply the developed framework to Indonesia.

Full textAbstract:
Climate variability and climate change have become important research topics also in economics. The objective of this thesis is not to forecast the future but to learn from the past by studying how two important climate change-related topics have affected Indonesian households. Delayed monsoon onset, El Niño, will become more frequent with climate change whereas palm oil production is a contributor to climate change. The first essay examines how variability in monsoon onset affects rural households' welfare in terms of household expenditure and farm profits. Using the Indonesia Family Life Survey (IFLS) data I find that households in the middle tercile of the expenditure distribution face the biggest albeit temporary losses from delayed monsoon onset. Half of the expenditure decline is due to increase in household size. Conditional on onset, rainfall intensity has only minor effects. The second essay uses the IFLS data to study how schooling and child labour are affected by delayed monsoon onset. The probability of continuing from primary to secondary school is reduced when a delayed onset coincides with the transition year. In other respects, monsoon onset does not affect education of rural children. However, riskier distribution of rain postpones school entry for young children. Moreover, delayed onset increases child labour. Using district-level data on palm oil production and area planted and national household survey (SUSENAS) the third essay studies the impact of oil palm expansion on household expenditure and health. Instrumental variable estimates exploit the historical production and district forest area as an exogenous source of variation. I find that smallholder production has a weak negative impact on household expenditure but this effect is not present among rural households. More, total production increases incidence of asthma in Kalimantan. The findings suggest that palm oil is not a panacea to increase rural welfare.

Full textAbstract:
This thesis focuses on using photovoltaic produced electricity to power air conditioners in a tropical climate. The study takes place in Surabaya, Indonesia at two different locations the classroom, located at the UBAYA campus and the home office, 10 km away. Indonesia has an average solar irradiation of about 4.8 kWh/m²/day (PWC Indonesia, 2013) which is for ideal conditions for these tests. At the home office, tests were conducted on different photovoltaic systems. A series of measuring devices recorded the performance of the 800 W PV system and the consumption of the 1.35 kW air conditioner (cooling capacity). To have an off grid system many of the components need to be oversized. The inverter has to be oversized to meet the startup load of the air conditioner, which can be 3 to 8 times the operating power (Rozenblat, 2013). High energy consumption of the air conditioner would require a large battery storage to provide one day of autonomy. The PV systems output must at least match the consumption of the air conditioner. A grid connect system provides a much better solution with the 800 W PV system providing 80 % of the 3.5 kWh load of the air conditioner, the other 20 % coming from the grid during periods of low irradiation. In this system the startup load is provided by the grid so the inverter does not need to be oversized. With the grid-connected system, the PV panel’s production does not need to match the consumption of the air conditioner, although a smaller PV array will mean a smaller percentage of the load will be covered by PV. Using the results from the home office tests and results from measurements made in the classroom. Two different PV systems (8 kW and 12 kW) were simulated to power both the current air conditioners (COP 2.78) and new air conditioners (COP 4.0). The payback period of the systems can vary greatly depending on if a feed in tariff is awarded or not. If the feed in tariff is awarded the best system is the 12 kW system, with a payback period of 4.3 years and a levelized cost of energy at -3,334 IDR/kWh. If the feed in tariff is not granted then the 8 kW system is the best choice with a lower payback period and lower levelized cost of energy than the 12 kW system under the same conditions.

Des coquilles de bénitiers géants (Famille Tridacnidae) ont étés utilisées pour reconstruire des conditions climatiques au cours des dernières périodes interglaciaires dans l’ île de Sulawesi , en Indonésie. Des analyses géochimiques sur des coquilles modernes, ont montré que ces organismes enregistrent effectivement la variation de l ’environnement dans lequel ils habitent , en termes de : température, salinité, précipitations et apports en nutriments . Le s résultat s principaux ont été la reproductibilité du signal géochimique dans deux espèces différentes et l’enregistrement des anomalies climatiques liées au phénomène La Niña en 2010. La datation à travers l’Uranium - Thorium a mis en évidence des récifs formés lors du début de la dernière période interglaciaire (MIS - 5) et de l’avant dernière interglaciaire ou MIS - 7. La comparaison entre reconstructions modernes et fossiles a donné comme résultats : 1) des conditions de température en moyenne plus froides et avec une saisonnalité réduite pour ces deux périodes (début du MIS - 5 et MIS - 7), liée à des conditions plus sèches.2) Ces paramètres répondent systématiquement aux variations du niveau marin et témoignent la forte interaction entre la circulation atmosphérique et océanique dans la région .3) La variabilité interannuelle SST/SSS présente des oscillations dans la même amplitude qu’aujourd’hui pour la période du MIS - 5, cependant pour le MIS 7, ces oscillations sont réduites autour de 50 % par rapport à l’actuelle . 4) Le Mg/Ca présente une forte variation taxonomique, des études complémentaires sont nécessaires pour enlever le facteur biologique du signal géochimique. 5) Le Ba/Ca et le 13C sont potentiellement liées aux processus d’upwelling et/ou variations de salinitéGiant clam shells (Tridacnidae family) were used to reconstruct climatic conditions during the last interglacial periods in Indonesia's Sulawesi Island. Geochemical analyzes on modern shells have shown that these organisms actually record the variation of the environment in which they live, in terms of: temperature, salinity, precipitation and nutrient inputs. The main results were the reproducibility of the geochemical signal in two different species, as well as the recording of the climatic anomalies related to the La Niña phenomenon in 2010. Uranium-series dating revealed reefs formed at the beginning of the last interglacial period (MIS-5) and the penultimate interglacial or MIS-7. The comparison between modern and fossil reconstructions gave the following main results: 1) colder average temperature conditions with reduced seasonality for both periods (beginning of MIS-5 and MIS-7) due to drier conditions.2) These parameters respond systematically to a decrease / increase of the sea level and testify the strong interaction between the atmospheric and ocean circulation in the region3) The interannual variability of SST / SSS presents oscillations in the same amplitude as today for the MIS-5 period, however for MIS 7, these oscillations are reduced around 50% compared to the current interglacial4) The Mg/Ca ratio has a strong taxonomic variation, additional studies are needed to remove the biological factor related to geochemical signal. 5) Ba/Ca present a potential use as tracers of upwelling processes and/ or variations in salinity. Giant clam shells (Tridacnidae family) were used to reconstruct climatic conditions during the last interglacial periods in Indonesia's Sulawesi Island. Geochemical analyzes on modern shells have shown that these organisms actually record the variation of the environment in which they live, in terms of: temperature, salinity, precipitation and nutrient inputs. The main results were the reproducibility of the geochemical signal

Full textAbstract:
The Intertropical Convergence Zone (ITCZ) is a key component of
Hadley cell circulation. In the Indo-Pacific Warm Pool (IPWP)
region, the seasonal migration of the ITCZ defines much of the
precipitation variability over the Maritime Continent. The
seasonal migration of the ITCZ in this region is also closely
related to the Australasian monsoon, which brings critical
rainfall to Asia and Indo-Australia, cumulatively home to
approximately 40% of the global population. On interannual
timescales, rainfall in the IPWP region is also connected with
zonal climate variability of the El Niño-Southern Oscillation
and Indian Ocean Dipole systems. Understanding the IPWP’s
climate sensitivities is therefore crucial to the improvement of
long-term prediction of rainfall and drought.
Abrupt changes in Atlantic Meridional Overturning Circulation
(AMOC) are known to have affected the strength of the Asian
monsoon during glacial and deglacial climate states. However,
there is still much uncertainty around the hydroclimate response
of the IPWP region to abrupt climate changes in the North
Atlantic. Speleothems are powerful archives for paleoclimatic
reconstruction, providing absolute-dated and often
highly-resolved records of past climate. Several speleothem
oxygen-isotope (δ18O) records from the central IPWP and Asian
summer monsoon regions provide decadally-resolved time-series of
past rainfall variability since the last glacial period. Many
studies have suggested a southward shift in the ITCZ in the IPWP
region during phases of reduced AMOC. However, existing IPWP
proxies have seasonal biases and conflicting responses, making it
difficult to determine the true extent of North Atlantic forcing
in this climatically important region. In Chapter 2 of this
thesis, I present a precisely-dated, high-resolution record of
eastern Indian Ocean hydroclimate variability spanning the last
16 ky (thousand years) from δ18O measurements in an
aragonite-calcite speleothem from central Sumatra. This
represents the western-most speleothem record from the IPWP
region and fills an important spatial gap in terrestrial
hydroclimate, facilitating assessment of Warm Pool sensitivity at
its lateral extent.
Petrographic and geochemical analysis reveals that the sample is
principally composed of aragonite but is punctuated by intervals
of primary calcite growth. In addition to mineralogical
determination by Raman spectroscopy, trace element analysis by
laser ablation ICP-MS reveals strongly antiphased behaviour
between magnesium and strontium attributed to the strong
preference of those elements for the calcite and aragonite
lattices, respectively. In Chapter 4, this relationship is
utilized to develop a quantitative correction for the stable
isotope fractionation offset between the two calcium carbonate
polymorphs identified in the speleothem and to quantify
partitioning coefficients for those elements into aragonite.
The corrected δ18O record demonstrates a clear deglacial
structure that includes 18O enrichment during the Younger Dryas
(~12.9-11.7 ka; thousand years ago) and 18O depletion during the
Bølling-Allerød (~14.7-12.9 ka), similar to the pattern seen in
speleothems of the Asian and Indian monsoon realms. In contrast,
other speleothem records from the IPWP show slight increases or
no change in δ18O during the Younger Dryas. To better interpret
the spatial pattern of speleothem δ18O change during the Younger
Dryas, Chapter 3 uses back-trajectory air parcel analysis to
identify primary moisture source regions and seasonal
distributions of moisture to IPWP speleothem sites. This
information is evaluated alongside modelled GISS ModelE-R vapour
source distributions to evaluate how moisture sources may have
changed during simulated hosing events analogous to the Younger
Dryas.
Chapter 4 considers the environmental controls that could account
for the mineralogy of the Sumatran speleothem sample. Shifts
between aragonite and calcite phases in the speleothem are partly
driven by environmental variability, with aragonite associated
with drier phases like the Younger Dryas and calcite generally
associated with increased detrital material. However, these
changes are more likely to be related to cave hydrology and
filtration rates than directly reflective of rainfall amounts.
Together, this research establishes a robust basis for
interpreting the climatic history retained in the 16 ky
speleothem δ18O record for Tangga Cave and provides context
relative to other speleothem records from the Indo-Pacific Warm
Pool region. This work demonstrates the extended reach of North
Atlantic abrupt forcing into the eastern tropical Indian Ocean,
supporting this conclusion with systematic analysis of the modern
hydroclimate system through use of isotope enabled climate models
and back-trajectory air parcel analysis.

Full textAbstract:
Climate change impacts have been shown to increase the social, economic and ecological vulnerabilities of poor groups in coastal communities of Asian countries. Mangunharjo village in Semarang city, Indonesia, has been identified as vulnerable to sea level rise, coastal erosion, tidal inundation and flooding, and the well-being of residents is threatened due to loss of livelihoods. In order to secure their future, the community has to enhance its resilience to climate change impacts, however, additional factors are undermining thepotential of a resilient and prosperous village. As resilience theory carried out in practice could negatively affect already marginalized people if trade-offs are not identified, a complementing theory is needed. This study develops a novel joint framework of resilience theory and environmental justice for analyzing the potential of enhancin gthe community’s resilience. It also explores what is needed for the village in order to increase its resilience. The framework revealed to be successful in identifying root problems and highlighted deficiencies in current resilience strategies. Moreover, the incorporation of environmental justice broadened the perspective of what could weaken the resilience ofthe village. Hence, an environmental justice perspective complements resilience theory as it identifies potential trade-offs and analyzes whose resilience is enhanced. The framework is argued to be a useful tool to secure resilience of a social-ecological system of various scales, however, further research is needed onthe optimal linkages of the two theories.

Full textAbstract:
[EN] Climate change has occurred in Indonesia, for example, increasing the surface air temperature, including in the Upper Citarum watershed. This phenomenon leads to a lack of water in the dry season, which lowers agriculture production and remains a great obstacle for agricultural activity. Meanwhile, human activity has produced severe LULC changes within the Upper Citarum watershed. This occurs due to the demands of the ever-increasing population growth in the region. As a result, rice field and forested areas have been sacrificed to compensate the urban increment. The general objective of this dissertation is to understand and analyze the impact of climate and LULC changes on the hydrological process and their relationship with historical and future changes by using spatially distributed modeling on the Upper Citarum tropical catchment. The distributed model TETIS has been implemented to obtain the results of past and future scenarios on the water and sediment cycles. Annual historical bathymetries in the reservoir were used to calibrate and validate the sediment sub-model involving Miller's density evolution and trap efficiency of Brune's equation. Climate change has been considered under RCP 45 and RCP 85 trajectories. Meanwhile, to overcome the LULC problem, historical and future LULCs have been studied. LCM model was used to forecast the LULC in 2029. The forecasted results of LCM model show, on one hand, a continuation in the expansion of urban areas at the expense of the contiguous rice fields. The results determined that deforestation and urbanization were the most influential factors for the alteration of the hydrological and sedimentological processes in the Upper Citarum Catchment. Thus, it decreases evapotranspiration, increases water yield by increasing all its components; overland flow, interflow and baseflow. The changes in LULC are currently producing and will produce in the future, a relatively small increment of erosion rates, increasing the area exceeds Tsl erosion. Sediment yield will increase in 2029 as the result of erosion increment. Other LULC scenarios such as conservation, government plan and natural vegetation scenarios are expected to have an increment in total evapotranspiration, the water yield is expected to decrease. Flood regime, erosion and sedimentation are reduced dramatically. Hence, it leads to a massive increment of reservoir and hydropower lifetime signed by a very long period of the lifetime. Climate change alters the magnitude of water balance and can be identified from the shift of infiltration, overland flow, interflow, baseflow and water yield. Those increments finally change the flood regime, catchment erosion. RCP 85 trajectory gives a bigger impact compared to RCP 45 trajectory on hydrological and sediment cycle. . LULC change results a bigger impact on water balance, flood regime, erosion and sedimientation. The combination of climate and LULC change give a bigger impact on the flows of water balance, erosion, flood, sedimentation and will be catastrophic for the hydropower operation of the Saguling Dam.[ES] El cambio climático ha afectado a Indonesia, por ejemplo, incrementando la temperatura del aire en la superficie, incluso en la cuenca del Upper Citarum. Este fenómeno conduce a la falta de agua en la estación seca, reduciendo la producción agrícola lo que es un gran obstáculo para su actividad. Además, la actividad humana ha producido cambios severos en LULC en la cuenca del Upper Citarum, Indonesia. Esto se debe al elevado crecimiento de la población en la región, por el que se han convertido campos de arroz y áreas boscosas en suelo urbano. De esta forma, el objetivo general de esta tesis es comprender y analizar el impacto de los cambios climáticos y LULC en el proceso hidrológico y su relación con los cambios históricos y futuros mediante el uso de modelos distribuidos espacialmente en la cuenca tropical del Upper Citarum. El modelo distribuido TETIS se ha implementado para obtener los resultados de escenarios pasados y futuros en los ciclos de agua y sedimentos. Se usaron batimetrías históricas anuales en el embalse para calibrar y validar el submodelo de sedimentos que involucra la evolución de la densidad de Miller y la eficiencia de retención de la ecuación de Brune. Con el fin de arrojar más luz sobre estos problemas, el escenario de cambio climático se ha implementado en base al modelo de cambio climático bajo las trayectorias RCP 45 y RCP 85. Además, para intentar resolver el problema LULC, también se ha implementado el LULC histórico y futuro. El modelo LCM se usó para pronosticar el LULC en 2029 y los resultados muestran, por un lado, una continuación en la expansión de las áreas urbanas a expensas de los arrozales contiguos. Los resultados determinaron que la deforestación y la urbanización fueron los factores más influyentes para la alteración de los procesos hidrológicos y sedimentológicos en la cuenca del Upper Citarum. Por lo tanto, disminuye la evapotranspiración, aumenta la producción de agua al aumentar todos sus componentes; escorrentía, interflujo y flujo base. Los cambios en LULC están produciendo y producirán, un incremento relativamente pequeño de las tasas de erosión, aumentando el área excede la erosión de Tsl. La producción de sedimentos aumentará en 2029 como resultado del incremento de la erosión. Se espera que otros escenarios de LULC como la conservación, el plan gubernamental y los escenarios de vegetación natural tengan un incremento en la evapotranspiración total, y se espera que la producción de agua disminuya. El régimen de inundación, la erosión y la sedimentación se reducen drásticamente. Por lo tanto, habrá un incremento de la vida útil del embalse y la energía hidroeléctrica. El cambio climático altera la magnitud del equilibrio hídrico y puede identificarse a partir del cambio de infiltración, escorrentía, interflujo, flujo base y producción de agua. Esos incrementos finalmente cambian el régimen de inundación y erosión de la cuenca. La trayectoria RCP 85 tiene un mayor impacto en comparación con la trayectoria RCP 45 en el ciclo hidrológico y de sedimentos. El cambio de LULC tiene un mayor impacto en el balance hídrico, el régimen de inundación, la erosión y la sedimentación. La combinación del cambio climático y LULC tiene un mayor impacto en los flujos de equilibrio hídrico, erosión, inundación, sedimentación y será catastrófico para la operación hidroeléctrica de la presa Saguling.
[CA] El canvi climàtic ha afectat Indonèsia, per exemple, incrementant la temperatura de l'aire en la superfície, inclús en la conca de l'Upper Citarum. Aquest fenomen conduïx a la falta d'aigua en l'estació seca, reduint la producció agrícola, el que és un gran obstacle per a la seua activitat. A més, l'activitat humana ha produït canvis severs en LULC en la conca de l'Upper Citarum, Indonèsia. Açò es deu a l'elevat creixement de la població en la regió, motiu pel qual s'han anat convertint camps d'arròs i àrees boscoses en sòl urbà. D'aquesta manera, l'objectiu general d'aquesta tesi és comprendre i analitzar l'impacte dels canvis climàtics i LULC en el procés hidrològic i la seua relació amb els canvis històrics i futurs per mitjà de l'ús de models distribuïts espacialment en la conca tropical de l'Upper Citarum. El model distribuït TETIS s'ha implementat per a obtindre els resultats d'escenaris passats i futurs en els cicles de l'aigua i sediments. Es van usar batimetries històriques anuals en l'embassament per a calibrar i validar el submodel de sediments que involucra l'evolució de la densitat de Miller i l'eficiència de retenció de l'equació de Brune. Amb la finalitat de donar més llum a aquests problemes, l'escenari de canvi climàtic s'ha implementat basant-se en el model de canvi climàtic davall les trajectòries RCP 45 i RCP 85. A més, per a intentar resoldre el problema LULC, també s'ha implementat el LULC històric i futur. El model LCM es va usar per a pronosticar el LULC en 2029 i els resultats mostren, d'una banda, una continuació en l'expansió de les àrees urbanes a costa dels arrossars contigus. Els resultats van determinar que la desforestació i la urbanització van ser els factors més influents per a l'alteració dels processos hidrològics i sedimentològics en la conca de l'Upper Citarum. Per tant, disminuïx l'evapotranspiració, augmenta la producció d'aigua en augmentar tots els seus components; escorrentia, interflux i flux base. Els canvis en LULC estan produint i produiran, un increment relativament xicotet de les taxes d'erosió, augmentant l'àrea excedix l'erosió de Tsl. La producció de sediments augmentarà en 2029 com a resultat de l'increment de l'erosió. S'espera que altres escenaris de LULC com la conservació, el pla governamental i els escenaris de vegetació natural tinguen un increment en l'evapotranspiració total, i s'espera que la producció d'aigua disminuïsca. El règim d'inundació, l'erosió i la sedimentació es reduïxen dràsticament. Per tant, hi haurà un increment de la vida útil de l'embassament i l'energia hidroelèctrica. El canvi climàtic altera la magnitud de l'equilibri hídric i pot identificar-se a partir del canvi d'infiltració, escorrentia, interflux, flux base i producció d'aigua. Eixos increments finalment canvien el règim d'inundació i erosió de la conca. La trajectòria RCP 85 té un major impacte en comparació amb la trajectòria RCP 45 en el cicle hidrològic i de sediments. El canvi de LULC té un major impacte en el balanç hídric, el règim d'inundació, l'erosió i la sedimentació. La combinació del canvi climàtic i LULC té un major impacte en els fluxos d'equilibri hídric, erosió, inundació, sedimentació i serà catastròfic per a l'operació hidroelèctrica de la presa Saguling.

Full textAbstract:
Indonesia launched a sovereign green sukuk in 2018 to fund green projects that can contribute to addressing climate change and achieving the Sustainable Development Goals. This issuance also marked the first sovereigngreen sukuk issuance in the world. Since then, Indonesia has issued five sovereign green sukuks and has mobilized 3.23 billion USD from these issuances. The money raised from these sovereign green sukuks has been directed to five eligible sectors: sustainable transportation, energy efficiency, renewable energy, waste toenergy and waste management, and resilience to climate change for disaster risk areas. This study aims to assess firstly how the money raised by the Indonesian sovereign green sukuk flows to the renewable energy powerplant projects. Secondly, this research also aims to identify what kind of barriers influence the flows of greensukuk money to the renewable energy power plant projects. A literature review is carried out to outline the barriers that have been known to exist in green bond and green sukuk financial flows from the previous research. Meanwhile, an exploratory single case study is employed to explore the flow of money and identify the barriersin Indonesia. The findings were analyzed using thematic analysis. Results show that there are two key actors in implementing the flow of money: the Ministry of Finance and the Ministry of Energy and Mineral Resources. The Ministry of Finance has a role as an issuer of the sovereigngreen sukuk. On the other hand, The Ministry of Energy and Mineral Resources has a role as the project ownerin the renewable energy sector. Therefore, it requires good coordination between them since each ministry hasdifferent responsibilities and priorities. Meanwhile, there are three frameworks that determine the mechanismof the flow of finance. Firstly, the state budget. Secondly, the Law No. 19/2008 concerning Sovereign Sukuk and its subordinate legislation, which is the Government Regulation No. 56/2011 concerning Project Financingthrough Sovereign Sukuk Issuance. Lastly, the Republic of Indonesia Green Bond and Green Sukuk Framework.The involvement of these frameworks shows that the implementation of the sovereign green sukuk must alignto the management of the state budget, must be compliant with the sovereign sukuk law and its subordinate legislation, and must follow the green principles according to the Republic of Indonesia Green Bond and Green Sukuk Framework. This study also shows two main barriers: the lack of coordination between ministries and the lack of capacity in some of the regional governments. The lack of coordination between ministries has affected the formulation of the impact report. Since the impact report is one of the key components in the sovereign green sukuk, the delay in delivering the impact report and the lack of quality in providing theinformation in the impact report can diminish the investor’s confidence. Meanwhile, the lack of capacity insome of the regional governments to manage and operate the renewable energy power plants funded by the green sukuk has led these projects could not give the impact as expected in reducing emission and achieving the SDGs target in the rural areas. Based on these results, this study suggests these recommendations: (1) The Ministry of Finance should consider establishing a directorate dedicated to exclusively handling green finance; (2) The ministries that own the projects should raise their awareness in reporting the impact of the green projects; (3) The coordination between the ministries should be improved in ensuring solid implementation in the issuance, allocation, and reporting phase; (4) The Ministry of Energy and Mineral Resources should ensure that the plan to build renewable energypower plants from the green sukuk are well-planned and well-executed. (5) The regional governments should increase their technical and financial capacity to ensure the sustainability of the renewable energy power plantsthey manage.

The purpose of this thesis is to explore how the unpredictability of climate change and natural disasters impact the risk perception of Swedish companies. The literature chapter that has been elaborated in this study describes theories that are associated with effects of climate change and natural disasters, risk management and knowledge. Further on, the research has been conducted with a qualitative method in order to gain a profounder understanding of the topic and how it influences the risk perception of Swedish companies. The study has further on been following a abductive research approach since the area of research was rather unexplored. We present the results of our study by answering to the research questions in the conclusion chapter that have been derived from the analysis. Furthermore, the conclusion chapter involves that the risks perception of the studied companies differentiates depending on the level and type on knowledge that the companies hold.

Full textAbstract:
L’humanité fait face aux défis urgents de réduire l’impact environnemental de l’agriculture, de changer les régimes alimentaires et d’accroître la production alimentaire. Le palmier à huile est une plante pérenne tropicale emblématique de ces défis. Alors que sa culture peut être à l’origine d’impacts environnementaux, le palmier à huile peut produire, en conditions optimales, 7 à 10 fois plus d’huile alimentaire que les cultures oléagineuses annuelles. Dans ce contexte, améliorer la durabilité de la production d’huile de palme est crucial, tant pour réduire les impacts environnementaux négatifs que pour garantir la sécurité alimentaire. L’application de fertilisants azotés (N) a été identifiée comme une source majeure d’impacts environnementaux dus à la culture du palmier. Des analyses de cycle de vie de l’huile de palme ont été réalisées pour quantifier les impacts et identifier des améliorations de pratiques agricoles. Cependant, les seuls modèles d’émissions disponibles pour estimer les pertes de N dans l’environnement sont généralement valides pour les cultures annuelles et en climat tempéré. L’utilisation de tels modèles dans l’analyse de cycle de vie peut mener à des résultats très incertains ou à une faible sensibilité aux pratiques. L’objectif global de ce travail de recherche était d’aider à l’identification de pratiques pour réduire les pertes de N dans l’environnement. Le cœur du travail était le développement d’un modèle estimant toutes les pertes de N dans les plantations, tout en étant sensible aux pratiques. L’étude s’est concentrée sur les flux de N dans les plantations de palmiers sur sols minéraux. Nous avons réalisé quatre étapes pour mener à bien cette recherche. Premièrement, nous avons mené une revue de littérature de tout le savoir existant concernant les flux et pertes de N dans les plantations. Deuxièmement, nous avons comparé 11 modèles existants, pouvant être utilisés pour prédire les pertes de N dans les plantations. Troisièmement, nous avons réalisé une analyse de sensibilité de Morris approfondie du modèle mécaniste APSIM-Oil palm. Quatrièmement, nous avons construit IN-Palm, un indicateur agri-environnemental pour les pertes de N dans les plantations. Nous avons utilisé la méthode INDIGO® et l’approche de modélisation par arbres de décisions flous pour développer IN-Palm, et nous avons validé cet indicateur en utilisant des mesures de lixiviation de N d’une plantation à Sumatra, Indonésie. Notre revue de littérature et notre comparaison de modèles ont montré que les particularités du palmier à huile peuvent affecter significativement les dynamiques et pertes de N. Nous avons identifié des manques de recherche et des incertitudes sur les pertes de N, leurs déterminants et la modélisation des particularités du palmier. Nous avons identifié les déterminants des pertes de N et du rendement dans le modèle mécaniste APSIM-Oil palm. Nous avons développé IN-Palm, qui utilise 21 variables d’entré facilement accessibles pour estimer chaque voie de perte de N. Les prédictions de lixiviation de N par IN-Palm étaient acceptables, et IN-Palm s’est montré efficace pour tester des changements de pratiques agricoles. Cette recherche constitue une synthèse exhaustive des connaissances et modèles disponibles pour les flux et pertes de N dans les plantations. L’un des principaux résultats est un nouvel indicateur agri-environnemental, IN-Palm, sensible aux pratiques et conditions locales, de même qu’utilisable en tant que modèle d’émission dans des approches holistiques. Cet indicateur peut être une base utile pour de futures recherches sur l’utilisation d’indicateurs agri-environnementaux pour réduire l’incertitude des analyses cycle de vie, et pour de futures adaptations à d’autres plantes pérennes tropicalesHumanity faces the challenges of urgently decreasing the environmental impact of agriculture, shifting diets and increasing food production. Oil palm is a tropical perennial crop emblematic of these challenges. While its cultivation can be associated with environmental impacts, oil palm can produce 3 to 7 t of edible oil ha-1 in optimal conditions, which is 7 to 10 fold higher than in annual oil crops. In this context, improving palm oil production sustainability is crucial for both reducing negative environmental impacts and ensuring food security. Application of synthetic nitrogen (N) fertilisers was identified as a major source of environmental impacts associated with the cultivation of oil palm. Life cycle assessments of palm oil have already been performed to help quantify impacts and identify potential improvements of management practices. However, the only available emission models to estimate N losses to environment are generally valid for annual crops and temperate climate conditions. The use of such general models in life cycle assessment may lead to very uncertain results or to low sensitivity of assessments to management practices. The overall objective of this research work was to help identify management practices to reduce N losses in the environment. The core of the work was hence to develop a model that estimates all N losses in oil palm plantations, while being sensitive to management practices. The study focused on N fluxes in industrial oil palm plantations on mineral soils. We performed four steps in order to complete the objectives of this research work. First, we conducted a literature review of all the existing knowledge about N fluxes and losses in plantations. Second, we compared 11 existing models that may be used to predict N losses in plantations. Third, we performed an in-depth Morris’s sensitivity analysis of one of the models, the APSIM-Oil palm process-based model. Fourth, we used all the information identified in the previous chapters, together with expert knowledge, to build IN-Palm, an agri-environmental indicator for N losses in oil palm plantations. We used the INDIGO® method and the fuzzy decision tree modelling approach to develop IN-Palm, and we validated this indicator using a field dataset of N leaching from a plantation in Sumatra, Indonesia. Our literature review and model comparison showed that oil palm peculiarities may impact significantly N dynamics and losses. We identified research gaps and uncertainties about N losses, their drivers and the modelling of oil palm peculiarities. We identified the main drivers of N losses and yield in the APSIM-Oil palm processbased model. We built IN-Palm, which uses 21 readily available input variables to estimate each N loss pathway. IN-Palm predictions of N leaching were acceptable, and IN-Palm has shown efficient to help testing management changes. This research constitutes a comprehensive synthesis of the available knowledge and models for N fluxes and losses in oil palm plantations. One of the main results is a novel agri-environmental indicator, IN-Palm, operationally-oriented, sensitive to local practices and environmental conditions, as well as potentially useable as an emission model for holistic approaches such as life cycle assessment. The INDIGO® method and fuzzy decision tree modelling approach were shown to be very well adapted for building agri-environmental indicators in contexts of knowledge scarcity. This indicator can be a useful base for further research about using agrienvironmental indicators to reduce uncertainty in life cycle assessment, and for future adaptations for other tropical perennial crops

Full textAbstract:
Humanity faces the challenges of urgently decreasing the environmental impact of agriculture, shifting diets and increasing food production. Oil palm is a tropical perennial crop emblematic of these challenges. While its cultivation can be associated with environmental impacts, oil palm can produce 3 to 7 t of edible oil ha⁻¹ in optimal conditions, which is 7 to 10 fold higher than in annual oil crops. In this context, improving palm oil production sustainability is crucial for both reducing negative environmental impacts and ensuring food security.
Application of synthetic nitrogen (N) fertilisers was identified as a major source of environmental impacts associated with the cultivation of oil palm. Life cycle assessments of palm oil have already been performed to help quantify impacts and identify potential improvements of management practices. However, the only available emission models to estimate N losses to environment are generally valid for annual crops and temperate climate conditions. The use of such general models in life cycle assessment may lead to very uncertain results or to low sensitivity of assessments to management practices.
The overall objective of this research work was to help identify management practices to reduce N losses in the environment. The core of the work was hence to develop a model that estimates all N losses in oil palm plantations, while being sensitive to management practices. The study focused on N fluxes in industrial oil palm plantations on mineral soils.
We performed four steps in order to complete the objectives of this research work. First, we conducted a literature review of all the existing knowledge about N fluxes and losses in plantations. Second, we compared 11 existing models that may be used to predict N losses in plantations. Third, we performed an in-depth Morris's sensitivity analysis of one of the models, the APSIM-Oil palm process-based model. Fourth, we used all the information identified in the previous chapters, together with expert knowledge, to build IN-Palm, an agri-environmental indicator for N losses in oil palm plantations. We used the INDIGO® method and the fuzzy decision tree modelling approach to develop IN-Palm, and we validated this indicator using a field dataset of N leaching from a plantation in Sumatra, Indonesia.
Our literature review and model comparison showed that oil palm peculiarities may impact significantly N dynamics and losses. We identified research gaps and uncertainties about N losses, their drivers and the modelling of oil palm peculiarities. We identified the main drivers of N losses and yield in the APSIM-Oil palm process-based model. We built IN-Palm, which uses 21 readily available input variables to estimate each N loss pathway. IN-Palm predictions of N leaching were acceptable, and IN-Palm has shown efficient to help testing management changes.
This research constitutes a comprehensive synthesis of the available knowledge and models for N fluxes and losses in oil palm plantations. One of the main results is a novel agri-environmental indicator, IN-Palm, operationally-oriented, sensitive to local practices and environmental conditions, as well as potentially useable as an emission model for holistic approaches such as life cycle assessment. The INDIGO® method and fuzzy decision tree modelling approach were shown to be very well adapted for building agri-environmental indicators in contexts of knowledge scarcity. This indicator can be a useful base for further research about using agri-environmental indicators to reduce uncertainty in life cycle assessment, and for future adaptations for other tropical perennial crops.

Full textAbstract:
Literature on the integration of cross-cutting issues, or policy integration, has given little attention to how policy-making processes allow for policy integration as well as present barriers. There is also little evidence of how sectoral ministries respond to crosscutting issues and in what way they are affected by pressure to address such issues, including those promoted by ‘competing’ agencies. Climate change presents a significant and important issue for integration into many areas of public policy. Many government ministries and departments are tasked with responding to climate change mitigation and adaptation objectives. Forestry is a key sector in building a response to climate change and so an investigation into how policy-makers and policy-making processes have responded to climate change can shed light on the integration of cross-cutting issues. The thesis reports on investigation into how the Ministry of Forestry, Indonesia, has responded to climate change and into the organisational arrangements developed in the response to climate change. The research developed an innovative framework for the analysis of policy integration, generating conclusions in relation to the policy process, organisational arrangements and the influence of key actors, including policy champions and boundary spanners.

Full textAbstract:
An idealized box model of the Indian Ocean is used to examine the hypothesis proposed by Godfrey and Weaver (1991) that the buoyancy-forced Leeuwin Current off the west coast of Australia is a manifestation of a basinwide thermohaline circulation driven by the Indonesian throughflow.The stronger Sverdrup circulation dominates the thermohaline circulation in most of the model ocean except near the eastern boundary.
The western boundary currents apparently play a very minor role in this basinwide thermohaline circulation. This differs from the warm water route proposed by Gordon (1986), and supports the alternative hypothesis that the heat from the equatorial Pacific is returned to the South Atlantic via the eastward-flowing Antarctic Circumpolar Current rather than past the Agulhas Retroflection.
The Indonesian throughflow is shown to significantly affect the surface heat fluxes and the meridional heat transport in the Indian Ocean. The role of the throughflow in maintaining the very warm climate of the Indian Ocean (a net exporter of heat) is described.
Large-scale, fairly long period ($>$100 days) barotropic eddies are found in the western portion of the basin for some solutions.

Full textAbstract:
The tropical warm pool waters surrounding Indonesia are one of the equatorial heat and moisture sources that are considered as a driving force of the global climate system. The climate in Indonesia is dominated by the equatorial monsoon system, and has been linked to El Niño-Southern Oscillation (ENSO) events, which often result in severe droughts or floods over Indonesia with profound societal and economic impacts on the populations living in the world's fourth most populated country. The latest IPCC report states that ENSO will remain the dominant mode in the tropical Pacific with global effects in the 21st century and ENSO-related precipitation extremes will intensify. However, no common agreement exists among climate simulation models for projected change in ENSO and the Australian-Indonesian Monsoon. Exploring high-resolution palaeoclimate archives, like tree rings or varved lake sediments, provide insights into the natural climate variability of the past, and thus helps improving and validating simulations of future climate changes.
Centennial tree-ring stable isotope records | Within this doctoral thesis the main goal was to explore the potential of tropical tree rings to record climate signals and to use them as palaeoclimate proxies. In detail, stable carbon (δ13C) and oxygen (δ18O) isotopes were extracted from teak trees in order to establish the first well-replicated centennial (AD 1900-2007) stable isotope records for Java, Indonesia. Furthermore, different climatic variables were tested whether they show significant correlation with tree-ring proxies (ring-width, δ13C, δ18O). Moreover, highly resolved intra-annual oxygen isotope data were established to assess the transfer of the seasonal precipitation signal into the tree rings. Finally, the established oxygen isotope record was used to reveal possible correlations with ENSO events.
Methodological achievements | A second goal of this thesis was to assess the applicability of novel techniques which facilitate and optimize high-resolution and high-throughput stable isotope analysis of tree rings. Two different UV-laser-based microscopic dissection systems were evaluated as a novel sampling tool for high-resolution stable isotope analysis. Furthermore, an improved procedure of tree-ring dissection from thin cellulose laths for stable isotope analysis was designed.
The most important findings of this thesis are: I) The herein presented novel sampling techniques improve stable isotope analyses for tree-ring studies in terms of precision, efficiency and quality. The UV-laser-based microdissection serve as a valuable tool for sampling plant tissue at ultrahigh-resolution and for unprecedented precision. II) A guideline for a modified method of cellulose extraction from wholewood cross-sections and subsequent tree-ring dissection was established. The novel technique optimizes the stable isotope analysis process in two ways: faster and high-throughput cellulose extraction and precise tree-ring separation at annual to high-resolution scale. III) The centennial tree-ring stable isotope records reveal significant correlation with regional precipitation. High-resolution stable oxygen values, furthermore, allow distinguishing between dry and rainy season rainfall. IV) The δ18O record reveals significant correlation with different ENSO flavors and demonstrates the importance of considering ENSO flavors when interpreting palaeoclimatic data in the tropics.
The findings of my dissertation show that seasonally resolved δ18O records from Indonesian teak trees are a valuable proxy for multi-centennial reconstructions of regional precipitation variability (monsoon signals) and large-scale ocean-atmosphere phenomena (ENSO) for the Indo-Pacific region. Furthermore, the novel methodological achievements offer many unexplored avenues for multidisciplinary research in high-resolution palaeoclimatology.Die tropischen Gewässer um Indonesien sind eine der äquatorialen Wärme- und Feuchtigkeitsquellen, die als treibende Kraft des globalen Klimasystems betrachtet werden können. Das Klima in Indonesien ist geprägt durch das Australisch-Indonesische Monsunsystem. Weiterhin besteht eine Verknüpfung mit El Niño-Southern Oszillation (ENSO) Ereignissen, die oft zu schweren Dürren oder Überschwemmungen in der Region mit tiefgreifenden gesellschaftlichen und wirtschaftlichen Folgen führen. Der neueste IPCC-Bericht legt dar, dass ENSO auch in den nächsten 100 Jahren das vorherrschende Klimaphänomen im tropischen Pazifik bleiben wird. Ferner wird davon ausgegangen, dass sich die ENSO-bezogenen Niederschlagsextrema intensivieren werden. Wenig Übereinstimmung herrscht jedoch bislang zwischen den Klimasimulationsmodellen in Bezug auf die voraussichtlichen Veränderungen von ENSO und dem Australisch-Indonesischen Monsunsystem. Hochaufgelöste Paläoklima-Archive, wie z.B. Jahrringe oder warvierte Seesedimente, geben Auskunft über die natürliche Klimavariabilität der Vergangenheit und können somit dazu beitragen, die Computersimulationen der künftigen Klimaentwicklung zu verbessern und zu validieren. Hundertjährige stabile Jahrring-Isotopenchronologien | Das Hauptziel dieser Doktorarbeit war es, dass Potenzial von tropischen Jahrringen zur Aufzeichnung von Klimasignalen herauszustellen und deren Evaluierung als Paläoklimaproxys. Im Detail wurden stabile Kohlenstoff- (δ13C) und Sauerstoff- (δ18O) Isotopenverhältnisse in Teakbäumen analysiert, und die ersten gut replizierten hundertjährigen (AD 1900-2007) stabilen Isotopenchronologien aus Java (Indonesien) erstellt. Dabei wurden verschiedene klimatische Einflussgrößen getestet, ob diese signifikante Korrelationen mit den Jahrringparametern aufzeigen. Weiterhin wurden hochaufgelöste intra-annuelle Sauerstoffisotopenzeitreihen erstellt, um den Transfer des saisonalen Niederschlagssignals in den jeweiligen Jahrring zu bemessen. Die ermittelte Sauerstoff-Isotopenchronologie wurde anschließend auf mögliche ENSO Signale hin untersucht. Methodische Errungenschaften | Ein zweites Ziel dieser Arbeit war es neue Verfahren zur Analyse stabiler Isotope in Baumjahrringen zu entwickeln und zu optimieren. Zwei verschiedene UV-Lasermikrodissektions-Systeme wurden getestet als neues präzises Präparationswerkzeug für stabile Isotopenstudien. Darüber hinaus wurde eine verbesserte Methode für die Probenaufbereitung stabiler Isotopenmessungen anhand von Zellulose-Dünnschnitten entwickelt. Die wichtigsten Ergebnisse dieser Doktorarbeit sind: I) Die hier vorgestellten neuartigen Techniken zu Probenvorbereitung verbessern die Analyse stabiler Isotope für Jahrringstudien in Hinsicht auf Präzision, Effizienz und Qualität. Es wurde gezeigt, dass die UV-Lasermikrodissektion eine wertvolle Technik ist, um die Beprobung von Pflanzengewebe in höchster Auflösung und beispielloser Präzision durchzuführen. II) Es ist gelungen, einen Leitfaden für ein modifiziertes Verfahren der Zelluloseextraktion an Gesamtholz-Dünnschnitten und der anschließenden Jahrringaufbereitung zu erstellen. Diese neuartige Methode optimiert die Analyse stabiler Isotopenzeitreihen in zweierlei Hinsicht: schnellere und effiziente Zelluloseextraktion und präzise Trennung der Jahrringsequenzen in inter-annueller bis intra-annuelle Auflösung. III) Die hundertjährigen stabilen Jahrring-Isotopenchronologien weisen signifikante Korrelationen mit dem regionalen Niederschlag auf. In den hochaufgelösten stabilen Sauerstoffisotopenwerten spiegelt sich deutlich das Niederschlagssignal der Trocken- und der Regenzeit wieder. IV) Die stabile Sauerstoffisotopenzeitreihe zeigt signifikante Korrelationen mit verschiedenen ENSO Phasen. Dies betont, dass die verschiedenen ENSO Phasen bei der Interpretation von tropischen Paläodaten zu berücksichtigen sind. Die Ergebnisse der Dissertation zeigen, dass saisonal aufgelöste stabile Sauerstoffisotopenchronologien von indonesischen Teakbäumen ein geeigneter Proxy für mehrhundertjährige Rekonstruktionen der regionalen Niederschlagsvariabilität (Monsun-Signale) und großräumiger Ozean-Atmosphären-Systeme (ENSO) für den Indopazifik ist. Darüber hinaus bieten die neuartigen methodischen Errungenschaften viele neue Ansätze für multidisziplinäre hochaufgelöste Studien in der paläoklimatologischen Forschung.

Full textAbstract:
A combined air-conditioning and water heating system using carbon dioxide as refrigerant has been investigated theoretically and experimentally. A computer program simulates the combined system has been developed and verified with experimental data. Effects of the following parameters to the system performance were examined: ratio of hot water load to rejected heat from air-conditioning system (load ratio), evaporation temperature, cooling medium temperature, inlet water temperature, hot water temperature, discharge pressure, and presence of internal heat exchanger. Main results were coefficient of performance and cooling capacity. It was concluded that there is an optimum pressure where the system reaches the highest coefficient of performance. Variation of coefficient of performance of the combined system with discharge pressures is similar to that of the airconditioning system without heat recovery. Load ratio affects the performance of the air-conditioning side. Coefficient of performance of the air-conditioning side (cooling-COP) increased with increasing load ratio. Optimum discharge pressure was affected by load ratio. Improvement of cooling-COP depends on both cooling medium and inlet water temperatures. The cooling-COP was lower at higher cooling medium temperature and higher inlet water temperature. When inlet water temperature is higher than cooling medium temperature, the cooling-COP will be lower compared to the airconditioning system without heat recovery. The system performance decreased as hot water temperature increased. The decrease is due to a need for higher discharge temperature to achieve maximum cooling-COP. Internal heat exchanger plays an important role in achieving higher system performance. Coefficient of performance is higher for the combined system with internal heat exchanger. The length of internal heat exchanger affects the cooling-COP and the location of the optimum discharge pressure. Estimation results used for calculating annual energy consumption in various type of buildings show that the largest energy saving can be achieve in hospitals, followed by in hotels and in multifamily buildings. Simple comparison of combined CO2 system with separated R22 and stand-alone water heating system show better total system efficiency for CO2 system.

Full textAbstract:
Au cours des dernières décennies, l'Indonésie a connu des transformations spectaculaires des terres avec une expansion des plantations de palmiers à huile au détriment des forêts tropicales. L'Indonésie est actuellement l'une des régions ayant le plus haut taux de transformation de la surface terrestre dans le monde à cause de l'expansion des plantations de palmiers à huile et d'autres agricultures qui remplacent les forêts à grande échelle. Comme la végétation est un modificateur du climat près du sol, ces transformations à grande échelle ont des impacts majeurs sur les variables biophysiques de surface telles que la température de surface, l'albédo, les indices de végétation (NDVI), sur le bilan énergétique de surface et le partitionnement énergétique.Ce travail de thèse vise à quantifier les impacts des changements d’usage des terres en Indonésie sur les variables biophysiques de surface. Pour évaluer ces changements à l'échelle régionale, des données de télédétection sont nécessaires.Étant une variable clé de nombreuses fonctions écologiques, la température de surface (LST) est directement affectée par les changements de la couverture terrestre. Nous avons analysé la LST à partir de la bande thermique d'une image Landsat et produit une carte de température de surface avec une haute résolution (30m) pour les basses terres de la province de Jambi à Sumatra (Indonésie), une région qui a subi de grandes transformations au cours des dernières décennies. La comparaison des LST, albédo, NDVI et évapotranspiration (ET) entre sept différents types de couverture terrestre (forêts, zones urbaines, terres incultes, plantations de palmiers à huile jeunes et matures, plantations d'acacias et de caoutchouc) montre que les forêts ont des températures de surface inférieures à celles des autres types de couvert végétal, ce qui indique un effet de réchauffement local après la conversion des forêts vers des plantations. Les différences de LST atteignaient 10,1 ± 2,6 ºC (moyenne ± écart-type) entre les forêts et les terres déforestées. Les différences de températures de surface s'expliquent par un effet de refroidissement évaporatif des forêts, qui compense l'effet de réchauffement de l'albédo.Basé sur des différences observées dans les variables biophysiques entre les plantations de palmiers à huile jeunes et matures, nous avons analysé trois images Landsat couvrant une chronoséquence de plantations de palmiers à huile pour étudier la dynamique des variables biophysiques de surface pendant le cycle de rotation de 20-25 ans des plantations de palmiers à huile.Nos résultats montrent que les différences entre les plantations de palmiers à huile à différents stades du cycle de rotation du palmier à huile se reflètent dans les différences du bilan énergétique de surface, du partitionnement énergétique et des variables biophysiques. Au cours du cycle de rotation des plantations de palmiers à huile, les différences de température à la surface diminuent graduellement et se rapprochent de zéro autour du stade mature de la plantation de palmiers à huile de 10 ans. Parallèlement, le NDVI augmente et l'albédo diminue à proximité des valeurs typiques des forêts. Le bilan énergétique de surface et le partitionnement énergétique montrent des tendances de développement liés aux variables biophysiques et à l'âge des plantations de palmiers à huile. Les nouvelles plantations et les jeunes plantations (<5 ans) ont un rayonnement net plus faible que les plantations de palmiers à huile matures, mais ont des températures de surface plus élevées que les plantations de palmiers à huile matures. (Suite et fin du résumé dans la thèse)Over the last decades, Indonesia has experienced dramatic land transformations with an expansion of oil palm plantations at the expense of tropical forests. Indonesia is currently one of the regions with the highest transformation rate of the land surface worldwide related to the expansion of oil palm plantations and other cash crops replacing forests on large scales. As vegetation is a modifier of the climate near the ground these large-scale land transformations have major impacts on surface biophysical variables such as land surface temperature (LST), albedo, vegetation indices (e.g. the normalized difference vegetation index, NDVI), on the surface energy balance and energy partitioning.Despite the large historic land transformation in Indonesia toward oil palm and other cash crops and governmental plans for future expansion, this is the first study so far to quantify the impacts of land transformation on biophysical variables in Indonesia. To assess such changes at regional scale remote sensing data are needed.As a key driver for many ecological functions, LST is directly affected by land cover changes.We analyze LST from the thermal band of a Landsat image and produce a high-resolution surface temperature map (30 m) for the lowlands of the Jambi province in Sumatra (Indonesia), a region which experienced large land transformation towards oil palm and other cash crops over the past decades. The comparison of LST, albedo, NDVI, and evapotranspiration (ET) between seven different land cover types (forest, urban areas, clear cut land, young and mature oil palm plantations, acacia and rubber plantations) shows that forests have lower surface temperatures than the other land cover types, indicating a local warming effect after forest conversion. LST differences were up to 10.1 ± 2.6 ºC (mean ± SD) between forest and clear-cut land. The differences in surface temperatures are explained by an evaporative cooling effect, which offsets an albedo warming effect.Young and mature oil palm plantations differenced in their biophysical. To study the development of surface biophysical variables during the 20 – 25 years rotation cycle of oil palm plantations, we used three Landsat images from the Jambi province in Sumatra/Indonesia covering a chronosequence of oil palm plantations.Our results show that differences between oil palm plantations in different stages of the oil palm rotation cycle are reflected in differences in the surface energy balance, energy partitioning and biophysical variables. During the oil palm plantation lifecycle the surface temperature differences to forest gradually decrease and approach zero around the mature oil palm plantation stage of 10 years. Concurrently, NDVI increases and the albedo decreases approaching typical values of forests. The surface energy balance and energy partitioning show a development patterns related to biophysical variables and the age of the oil palm plantations. Newly established and young plantations (< 5 years) have less net radiation available than mature oil palm plantations, yet have higher surface temperatures than mature oil palm plantations. The changes in biophysical variables, energy balance and energy partitioning during the oil palm rotation cycle can be explained by the previously identified evaporative cooling effect in which the albedo warming effect is offset. A main determinant in this mechanism is the vegetation cover during the different phases in the oil palm rotation cycle. NDVI as a proxy for vegetation cover showed a consistent inverse relation with the LST of different aged oil palm plantations, a trend that is also observed for different land use types in this study.

Java, l'île principale de l'archipel indonésien a vu la construction, depuis les années 1960, de nombreux grands barrages. Leurs rôles sont multiples, passant du contrôle des flux liquides (écrêtage des crues et soutien des étiages) à l'approvisionnement en eau des grandes agglomérations urbaines et des terres agricoles. Ils jouent également le rôle important de fournisseur d'énergie. Depuis leur mise en eau, on assiste à un comblement rapide des réservoirs liés à des taux d'érosion qui figurent parmi les plus élevés du monde. La diminution importante de leur efficacité entraîne par conséquent de nombreuses répercussions néfastes sur le milieu et les sociétés. Les objectifs de cette recherche sont ainsi de déterminer, avec des approches multiples (SIG, télédétection, base de données hydro-climatiques, sondages lacustres...), les taux et les rythmes de remplissage de ces réservoirs, agissant comme indicateurs de l'érosion dans leur bassins-versants respectifs. Il s'agira de mettre en évidence les facteurs principaux influant sur cette forte sédimentation et de mettre en place des outils permettant de venir en aide aux organismes chargés de la gestion des bassins-versants javanaisSince the Sixties, a large number of dams have been built in the Indonesian archipelago's main island, Java. Their rôle are multiple, going from liquid flows control (flood – peak shaving and low flow support) to water supply of great urban areas and agricultural lands. They also are an important energy supplier. After their watering, a fast filling of the tanks related to rates of erosion that appear among the highest in the world, has been observed. This significant efficiency decrease involves multiple negative impacts on environment and utilities. Through a multiple approach (GIS, remote sensing, hydroclimatic databases, lake surveys...), the objectives of this research are to determine the sedimentary transfer rates and pace within the studied basins, which act as erosion indicators in their respective basins. The key determinants affecting this high sedimentation will be highlighted and a software will be developed with the aim to provide Javanese river basins authorities with new tools

Climate change and increasing variability will have especially profound adverse impacts upon the lives of rural communities in developing countries. However, households have differing asset bases and livelihood strategies, and therefore may have variable levels of vulnerability. Designing appropriate climate adaptation strategies must take these differences into account. This study examined the heterogeneity of vulnerability amongst rural communities in Lombok, Indonesia, and considers implications for climate adaptation policy interventions. Three villages, with differing natural resource bases, were selected as case studies: forest, rain-fed agriculture, and coastal fisheries and aquaculture. Based on a questionnaire survey (n=250), a household typology was generated. Cannon's (2008) vulnerability framework was applied to analyse the factors driving vulnerability for each household type in the villages. Interviews (n=72) with individuals from different household types were also employed to determine their perceptions about vulnerability and adaptation preferences. Participatory focus group discussions and social network mapping were also utilised to triangulate causes of vulnerability and dependencies between household types.
Three main key conclusions emerged. First, although climate variability contributes to increased livelihood vulnerability, the degradation of traditional institutions through modernisation and social change was considered to be a more serious problem. In particular, traditional institutions are an important source of adaptive capacity for poorer households. Second, community structures are complex, with different household types depending on one another for support. Social cohesion and mutual assistance are important for maintaining livelihood activities both in difficult times and during normal daily situations. Third, current development programs do not account for this variability of household types, their adaptation needs or the linkages between them. As a result, wealthier households benefit more than poorer ones, and there is little evidence of 'trickle down' benefits from rich to poor. This inequality could potentially lead to maladaptation.
These patterns were similar across all case study villages. However, the dynamic interactions among households types differed based on the strength of social cohesion and local institutions. Therefore adaptation policies must be better designed and be more egalitarian. Specifically they must restore and maintain traditional institutions and social capital. The 'vulnerability components framework' from Cannon (2008) was used to identify necessary intervention points for different household types. These components are interlinked to each other and enable understanding of what causes some people to be more at risk of a hazard than others.

Research Doctorate - Doctor of Philosphy (PhD)The climate evolution of the southern sub-equatorial tropics during marine isotope stage (MIS)5a/b and the Holocene is explored using geochemical tracers from speleothems on Flores island, Indonesia. Oxygen isotope measurements from two precisely-dated stalagmites reveal that the Australian-Indonesian monsoon increased during the Younger Dryas (YD) cooling event, when Atlantic meridional overturning circulation was relatively weak. Monsoon precipitation intensified even more rapidly from 11 to 7 ka ago, when the Indonesian continental shelf was flooded by global sea-level rise. Analysis of oxygen (δ18O) and hydrogen (δD) isotope ratios from speleothem fluid inclusions shows that inclusion-δ18O values vary in phase with speleothem calcite δ18O during the Holocene, confirming that calcite δ18O primarily reflects variations in the δ18O of meteoric rainfall. Cave drip-water temperatures, reconstructed from coupled measurements of δ18O in speleothem calcite and fluid inclusions, remained relatively constant through the Holocene but were significantly cooler during the YD, consistent with the high northern latitudes. To help confirm the stable isotope records, trace elements were used to reconstruct the position of the austral summer inter-tropical convergence zone and east Indonesian rainfall variability during the Holocene. Mg/Ca and Sr/Ca ratios correlate significantly with one another, and with δ18O and δ13C, throughout the record suggesting that the trace element ratios were dominated by prior calcite precipitation, a process whereby degassing in the vadose zone during periods of low recharge causes deposition of calcite and disproportionate loss of Ca2+ ions (relative to Mg2+ and Sr2+) ‘upstream’ of the stalagmite. Comparison of speleothem δ18O time-series from Flores and Borneo shows that they vary in unison for much of the Holocene. However, there is an exception during the mid-Holocene when a distinct anomaly in δ18O in the Borneo record, possibly caused by a change in the circulation of the Australian-Indonesian summer monsoon (AISM) in response to a period of positive IOD-like conditions in the eastern Indian Ocean, occurred between the two regions. A stalagmite reconstruction of Indo-Pacific climate through the interval 84 - 91 ka shows that the lower-frequency oxygen isotope trend indicates that the AISM was largely controlled by local summer insolation during this time, while the carbon isotopes show a pattern that is closer linked with northern polar-latitude ice-core records. Most notably, an abrupt decrease in the temperature-controlled δ13C values at the MIS 5a/b transition occurs in parallel with GIS 21 in the GISP2 δ18O and CH4 records highlighting the strong connection between the IPWP and North Atlantic during the last glacial period.
