Public awareness of environmental problems and the need to work towards their solution have been heightened at international conferences for over two decades.Knowledge of the range of environmental perspectives and attitudes, and understanding the reasons for them, are important requirements for decision-making when dealing with global environmental issues. It is argued that culture may impact on environmental views and attitudes may shape worldwide views that give rise to them.In this study, Australian, Maldivian and Indonesian trainee teacher communities served as sources of data to examine the influence of culture on environmental attitudes. The three communities examined viewed the term 'environment' differently, and that was one reason for different environmental attitudes being exhibited.It was also found that knowledge about environments was obtained from different sources, and some individuals and communities exhibited both pro-New Environmental Paradigm and pro-Human Exemptionalist Paradigm views simultaneously. This is inconsistent with a western view of environmentalism. The findings have implications for environmental education curricula and the negotiation of global environmental issues.Doctor of Philosophy (PhD)

We examined how fast- and slow-growing families (based on height at 10 years) of Pinus banksiana Lamb. are affected by a climate altered by CO$ sb2$ during their first growing season. Our primary objective was to evaluate the possibility that genotypes performing best under present conditions may not necessarily do best under projected warmer climate. Seedlings were grown for six months in two climatic environments (350 $ mu$L/L CO$ sb2$ x present temperatures and 700 $ mu$L/L CO$ sb2$ x 4$ sp circ$C warmer temperatures) and with 100 ppm and 5 ppm nitrogen.The CO$ sb2$T$ sp circ$ environment had a significant effect on most biomass components of seedlings and water-use efficiency but not on height and other growth variables. The nitrogen fertilization was generally the most significant effect of the treatments for most growth variables.
All the families responded in a similar way to variations in the growing environments except for WUE. Family differences were more important for measurements of height and growth variables than for biomass components. The architecture of seedlings was also highly variable between families. Norm of reaction graphs were built for several growth variables to outline which families were overall most successful in an enriched CO$ sb2$T$ sp circ$ environment. Of the 15 families studied, four of them were classified as most successful in a projected high CO$ sb2$T$ sp circ$ climate.

Global climate change is anticipated to raise the overall temperatures and is likely to increase future mortality attributable to heat. Predicting future health consequences of higher temperatures at the regional, national and global level based on historical temperature-mortality relationships can be challenging due in part to the uncertainties in the location-specific temperature-mortality relationship, the heat threshold, and how populations will adapt or acclimatize. This study reviews published estimates of the warm season temperature-mortality relationships around the world and explores the heterogeneity in terms of the magnitude of the relationship and the threshold. We also investigate the potential effects of adaptation and acclimatization on the estimates of excess heat-related deaths based on empirical evidence, and propose a method that can be used in future projections to address the uncertainties. This study contributes to the literature of projecting the future public health burden of heat-related effects, which provides valuable information to climate policy decision making.

Jiménez, Godínez Miguel Ángel. "Global change and local economic restructuring : the case of Mexico City." Thesis, London School of Economics and Political Science (University of London), 2015. http://etheses.lse.ac.uk/3080/.
Анотація:
This thesis is about economic transformation in Mexico City between 1980 and 2000. It explores the extent to which Mexico City’s economic restructuring process has been caused by trade liberalisation. The thesis assesses the extent to which industries located in Mexico City reacted to a reorientation in production focus, characterised by the shift from national to international markets. It analyses in detail the pace and geography of neo-liberal economic change, and its effects upon a specific location. It also evaluates the role played by global economic agents in gauging the forces influencing economic restructuring in Mexico, and particularly in Mexico City. At the core of this restructuring process is the change in regional industrial location patterns in Mexico, as well as the decline of manufacturing – with regard to production and employment – in Mexico City and its rise as a service centre. The thesis therefore engages with current debates on new economic geography on the one hand and globalisation on the other, focusing attention on the possible emergence of a group of “global” urban centres embedded in a broader network of cities in developed and developing countries alike, which connect global production circuits and coordinate global/regional markets. More concretely, the thesis focuses on the automotive and consumer electronics industries with the aim of understanding the causes and effects of economic events in terms of location decisions, particularly those made by transnational corporations. By placing the empirical processes of economic restructuring within the theoretical context of trade liberalisation and globalisation, I seek to make an original contribution to social science debates about the way industry reacts to economic signals and how global processes, despite taking place in specific locations, have wide-reaching effects upon social welfare, mainly though the transformation of local labour markets.

Consumption has emerged as a pivotal concept in environmental sustainability debates. Since the 1992 Earth Summit, there has been an increasing focus on the role that consumption and consumer lifestyles play in global environmental change. Agenda 21 called on countries to promote more 'sustainable consumption' patterns and lifestyles. Despite these recommendations, there are significant political and ideological challenges to implementing effective sustainable consumption policies at a global and national level. This thesis explores the politics of sustainable consumption in New Zealand. Using critical discourse analysis and in-depth semi-structured interviews with nine consumers, I employ post-structural and cultural geography theories to unpack the problematic nature of sustainable consumption. In particular, I examine dominant environmental and consumption discourses to explore why barriers to sustainable consumption exist. It is important to examine these issues from a socio-cultural perspective, as the dominant hegemonic discourses relating to the environment and sustainability shape both policy responses and public understandings of environmental change and sustainability issues. Prevailing policy responses to environmental change in New Zealand construct the 'environmental problem' in narrowly scientific and economic terms. Concern has centred on 'managing' carbon emissions, rather than addressing the underlying drivers of environmental degradation which lie in current political-economic structures and consumption levels. As such, environmental policy has been embedded within an ecological modernisation discourse which links sustainability with notions of 'progress' and efficiency. Under this discourse, the consumer has been repositioned as an important 'political' agent responsible for fostering sustainable consumption and environmental care. Through largely non-political and non-regulatory measures, consumers have been encouraged to reduce their 'carbon footprints' by considering the environmental impacts of their daily personal consumption habits. This approach has individualised and depoliticised environmental issues, obscured the complexities of personal consumption and sustainability, and left limited options for participation in processes of change.

The aim of this thesis was to examine the way individual responses to global climate change are determined by intrapersonal, social and experiential factors through three streams of research. The first stream employs cross-sectional and experimental methods to demonstrate that the influence of climate change information on behavioural intentions among two African populations is largely conveyed indirectly through perceived threat and concern. My findings support a view that a failure to account for the indirect effects of knowledge may have resulted in a systematic underestimation of its importance as a basis for environmental action. In the second stream, I sought to resolve previous inconsistencies in the evidence for a link between flooding experiences and climate change engagement. Using secondary data analysis, I found that political affiliation modulates the link between flooding experience and preparedness to engage in climate change mitigation behaviour in the UK, such that the indirect links between flooding experience and preparedness to reduce energy use, and willingness to pay higher prices for energy efficient products, was stronger among left-leaning voters. These results were followed up with four experimental studies in which flooding experience was operationalised with a mental simulation technique. The experiments were designed to examine how values and attribution may moderate the effects of flooding experiences on climate change attitudes, but they did not yield any conclusive findings. Finally, I examined the interplay between descriptive and injunctive social norms as influences of behavioural engagement with climate change using cross-sectional and experimental data. I found that social norms may influence behavioural engagement with climate change indirectly through their effects on individuals' perceptions of, and emotional responses to, the problem. However, the nature of this influence may also be dependent on the convergence of the two norm types and the level of individuals' intrinsic prioritization of pro-environmental outcomes.

Climate change is quickly becoming an important global concern with considerable and varied long-term consequences. In order to lessen the effects of this phenomenon it is necessary to institute regulatory policies that control carbon dioxide emissions, since they have been shown to directly correlate with temperature changes. Despite the prevalence of climate change initiatives, both internationally and within the United States, there is no comprehensive national policy with respect to the issue. The public and political conditions in the United States are presently ideal for the institution of a federal climate change policy, the most effective of which involves the incorporation of multiple emissions reductions measures

Анотація:
This thesis argues that international regimes exist within the international legal order. The use of regime theory to explain international regulation of an issue-area, although first introduced as a legal concept, has been primarily explored in the discipline of international relations. That discipline has for the most part, however, under-emphasised international law. In an effort to promote interdisciplinary research on the nature of the international legal order, this thesis explores the concept of international regimes within the international legal order, using examples of global environmental change. A discussion of the schools of thought within international law is undertaken, with the policy-oriented approach to be utilised in this thesis. The policy-oriented school, which views international law as a process, can incorporate the process of regime formation and development within its framework. An examination of the general international law applicable to climate change and ozone layer depletion is then undertaken, to help explain the need for regime formation in those areas. A discussion of the role of regimes within international law follows, including their formation, maintenance, source of legal obligation, and compliance mechanisms. The strength of a regime's normative or shared expectations, or norms and rules, depends on the shaping of cognitive expectations, or knowledge. These cognitive expectations are in turn dependent on the degree to which uncertainty regarding issues critical to the particular regime has been overcome. An examination of the critical issues particular to climate change and ozone layer depletion is made, as well as how regimes can overcome uncertainty. This is followed by a discussion of regime catalysts. Analyses of the ozone layer depletion and climate change regimes are then made, and an argument for their inclusion as law within the policy-oriented school is made. The thesis concludes that regimes are present within the international legal order and play a vital role in maintaining that order. Thus, this thesis aims to make an original contribution to the discipline of international law through the study of regimes, which signal the presence of the international legal order where it has previously been ignored or deemed nonexistent.

Анотація:
Recent science policy has stressed the need for academic research to be 'relevant' to the needs of society. Greatest emphasis has been placed on research that supports wealth creation, but other goals such as supporting the quality of life and the effectiveness of public policy have also been highlighted. University research is increasingly seen as a key resource in addressing challenges such as global environmental change. Connected to these developments in science policy, academic commentators have suggested that a new 'mode' of research is emerging - research conducted 'in the context of application'. However, there are significant questions over whether the current organisation of research in the university sector can facilitate this 'relevant' mode of research. This thesis investigates the tensions around the conduct of socially relevant research in British universities. It puts forward a novel conceptual framework for investigating the factors affecting the conduct of relevant research, arguing that researchers are influenced by five factors: academic disciplines, research institutions, research funding sources, personal motivations, and wider policy 'discourses'. The thesis analyses the pressures towards relevant research and the characteristics of such research, which tends to be inter-disciplinary, problem-centred and interactive. The thesis details how the factors identified in the conceptual framework affected the work of a group of social scientists involved in global environmental change research during the 1990s. The thesis demonstrates that 'relevant' research may bring not only a range of benefits but also certain potential 'hazards' to researchers conducting relevant research. There are therefore significant tensions around its implementation, tensions that the thesis suggests can be traced to the institutionalisation of academic research in universities. These tensions have significant implications for the implementation of relevant research in universities

The response of global soil respiration (Rs) to climate change determines how long the land can continue acting as a carbon sink in the future. This dissertation research identifies how temporal and spatial variation in environmental factors affects global scale Rs modeling and predictions of future Rs under global warming. Chapter 1 describes the recommend time range for measuring Rs across differing climates, biomes, and seasons and found that the best time for measuring the daily mean Rs is 10:00 am in almost all climates and biomes. Chapter 2 describes commonly used surrogates in Rs modeling and shows that air temperature and soil temperature are highly correlated and that they explain similar amounts of Rs variation; however, average monthly precipitation between 1961 and 2014, rather than monthly precipitation for a specific year, is a better predictor in global Rs modeling. Chapter 3 quantifies the uncertainty generated by four different assumptions of global Rs models. Results demonstrate that the time-scale of the data, among other sources, creates a substantial difference in global estimates, where the estimate of global annual Rs based on monthly Rs data (70.85 to 80.99 Pg C yr-1) is substantially lower than the current benchmark for land models (98 Pg C yr-1). Chapter 4 simulates future global Rs rates based on two temperature scenarios and demonstrates that temperature sensitivity of Rs will decline in warm climates where the level of global warming will reach 3°C by 2100 relative to current air temperature; however, these regional decelerations will be offset by large Rs accelerations in the boreal and polar regions. Chapter 5 compares CO2 fluxes from turfgrass and wooded areas of five parks in Blacksburg, VA and tests the ability of the Denitrification-Decomposition model to estimate soil temperature, moisture and CO2 flux across the seasons.
Cumulatively, this work provides new insights into the current and future spatial and temporal heterogeneity of Rs and its relationship with environmental factors, as well as key insights in upscaling methodology that will help to constrain global Rs estimates and predict how global Rs will respond to global warming in the future.Ph.

Despite high adaptive capacity, national climate change legislation in the industrialized world has been varied in its application and success. Many governments and scholars cite national security as grounds for climate change mitigation, despite the indirect threat that climate change poses to traditional security activities. The particular contribution of this thesis will be to discuss the viability of securitization as a strategy for creating a political coalition strong enough to bypass resistant domestic actors (particularly the energy industry) and pass meaningful climate change legislation; whether securitization gives a government enough support, from enough actors, to mitigate climate change. Robyn Eckersley and Peter Christoff’s work on the influence of domestic actors, national discourses, and strategies of capital accumulation on climate change policy development will form the foundation of this thesis. Particular focus will be placed on critical energy infrastructure in both of the case study countries due to its characteristics as a national security priority, its importance to the growth of the economy, and the part that this infrastructure plays in both causing and adapting to climate change. This thesis is attempting to discover the institutions and ideas that may enable a state to tackle one of the biggest and most complex common goods issues in history. In particular, can the invocation of security, as it is proposed in much of the securitization literature, elevate climate change to such a vital position in politics that ‘veto players’ lose their ability to veto? If veto players are more amenable to mitigation when climate change is presented as a security threat, then a more aggressively securitized policy may be called for.

Анотація:
The formal access of transnational actors (TNA) to international organizations (IO) has increased steadily over the past five decades, and a growing body of literature is at the moment concerned with the theoretical and normative implications of these developments. However, very little is known as of yet about who the TNAs in global governance are, where they come from, which issue areas they focus on, and when and where they choose to participate. Using analytical tools from interest group theory, in particular a subfield called population ecology, this study describes and explains the chronological development of two populations of TNAs in global governance, namely the observer communities of the United Nations Framework Convention on Climate Change and the United Nations Convention on Biological Diversity. TNAs’ financial resources and their geographical proximity to global governance venues emerge as important factors influencing their capacity to participate, causing these TNA populations to be stratified and volatile.

Les changements environnementaux globaux (CEG) menacent les écosystèmes marins et les populations humaines qui en dépendent. Une recherche scientifique croissante tente d’évaluer les impacts des changements environnementaux sur les écosystèmes et les services écosystémiques, notamment pour guider les politiques publiques. Focalisée sur les systèmes socio-écologiques (SSE) des récifs coralliens, cette thèse analyse les approches proposées dans la littérature et conçoit de nouvelles méthodologies, évaluations et indicateurs pour guider la science et l’action publique. Nous montrons qu’une stratégie de recherche régionale doit prendre en compte la complexité et produire de meilleures projections des impacts des CEG sur les récifs coralliens et les services associés. Nous cartographions des indicateurs à l’échelle globale pour évaluer où la dépendance des sociétés aux récifs coralliens sera affectée par les menaces globales dues à un niveau de CO2 élevé. Nous analysons comment la science répond aux impacts des CEG sur les récifs coralliens et nous identifions des pistes pour la recherche. Enfin, nous opérationnalisons une facette de la vulnérabilité, la capacité d’adaptation écologique, pour servir d’outil pour évaluer l’effectivité des actions locales dans un contexte de CEG. Ce manuscrit contribue à des avancées théoriques et méthodologiques sur l’évaluation des impacts, de la vulnérabilité et de l’adaptation aux CEG. Il développe des approches interdisciplinaires pour l’étude des SSE et des services écosystémiques, ciblant les récifs coralliens comme étude de cas. Enfin, il analyse l’émergence d’un champ scientifique sur les solutions aux GEC pour les récifs coralliensGlobal environmental change (GEC) in the ocean threatens marine ecosystems and the people who depend on them. A growing scientific effort is attempting to evaluate the impacts of environmental changes on ecosystems and ecosystem services and guide policy-making to respond to this global issue. Focusing on social-ecological systems of coral reefs, this thesis critically reviews the approaches put forward in the literature to understand gaps and to design new methodologies, assessments, and indicators to guide science and policy. Our findings show that a regionally targeted strategy of research should address complexity and provide more realistic projections about the impacts of GEC on coral reefs ecosystems and ecosystem services. We map global-scale indicators to understand where human dependence on coral reef ecosystems will be affected by globally-driven threats expected in a high-CO2 world. We then analyze how science is responding to the challenge posed by GEC on coral reefs and to identify gaps in research.Finally, we attempt to operationalize an overlooked component of vulnerability assessments, ecological adaptive capacity, to serve as a tool to help assess where local actions can be effective in the context of climate change. This manuscript contributes to theoretical and methodological advances to evaluate impacts, vulnerability and adaptation to GEC. It develops interdisciplinary approaches for the study of social-ecological systems and ecosystem services, targeting coral reefs as a case study. Finally, it synthesizes critically the emergence of a scientific field on solutions to GEC for coral reef social-ecological systems

The most devastating effects of climate change may be avoided if humans reduce activities that produce greenhouse gases and engage instead in more sustainable ecological behaviors. The current mixed methods study of 279 undergraduate students explored whether environmental worldview, belief in climate change, knowledge of climate change, personal efficacy, and intention to address climate change influenced participants’ engagement in ecological behavior. Results indicated that those with a stronger intention to address climate change and a more ecocentric worldview reported significantly more ecological behavior. Next, the study examined whether participants’ intentions to address climate change mediated the relationship between their belief in climate change and engagement in ecological behavior and whether intentions mediated the relationship between efficacy and ecological behavior. Intentions to address climate change did not mediate the relationship between belief and ecological behavior but fully mediated the relationship between efficacy to address climate change and ecological behavior.

Per molti anni i biocarburanti sono stati considerati un’alternativa verde e sostenibile ai carburanti fossili allo scopo di ridurre le emissioni di gas ad effetto serra (GHG) nel settore dei trasporti. Per questa ragione, negli ultimi anni, molte politiche europee hanno promosso la produzione e il consumo di biocarburanti. Tuttavia recentemente sono sorti dubbi sulla loro effettiva sostenibilità. In particolare, molti studi scientifici affermano che se aggiungiamo alle emissioni che derivano dal ciclo di vita dei biocarburanti, quelle provenienti dal cambiamento d’uso del suolo indiretto (iLUC), i benefici ambientali di alcuni biocarburanti potrebbero assottigliarsi notevolmente.
Alimentato da questi dubbi, l’obiettivo di questa tesi è quello di prevedere le conseguenze economico-ambientali a livello globale di un aumento di consumo di biodiesel in Europa dal 2001 al 2020, applicando i parametri stabiliti dalla Direttiva RED e verificare se i criteri di sostenibilità definiti dalla RED stessa verranno soddisfatti.
A questo scopo, è stato utilizzato il modello di equilibrio generale GTA-BIO, un modello in grado di analizzare i collegamenti tra biocarburanti, agricoltura, commercio internazionale e le conseguenze ambientali in termini di cambiamento d’uso del suolo ed emissioni.
I risultati della simulazione confermano i dubbi della letteratura scientifica sulla sostenibilità dei biocarburanti di prima generazione.
La domanda di biodiesel in Europa dopo l’implementazione degli obiettivi della RED risulterebbe essere così elevata che la UE necessiterebbe di aumentare fortemente l’importazione di materie prime per la produzione di biodiesel, una delle cause della perdita prevista di benessere economico. Inoltre, l’incremento del consumo di biodiesel in Europa dovrebbe comportare una diversione di intermedi e fattori produttivi da altri settori, soprattutto da quelli che competono per la terra. La diminuzione dell’offerta di piante destinate all’alimentazione umana o alla mangimistica (poiché sostituite da piante per biocarburanti) causa un aumento dei loro prezzi e di quelli degli output che dovrebbero originare (cibo e mangimi). Il conflitto tra il settore del cibo e quello dei biocarburanti è la forza motrice del cambiamento d’uso del suolo indiretto; infatti, all’aumentare dei prezzi delle commodities agricole, i produttori hanno interesse ad aumentarne la produzione su terreni precedentemente non agricoli (es. foreste e pascoli). Secondo la simulazione, la maggior parte del cambiamento d’uso del suolo avviene in Europa, soprattutto a discapito delle foreste. Le emissioni totali di GHG che ne conseguono si attestano sui 168 gCO2/MJ all’anno per 20 anni, il che significherebbe il mancato rispetto dei requisiti di riduzione delle emissioni stabilite dalla RED.For many years, biofuels have been considered a cleaner, greener alternative to fossil fuels in order to reduce greenhouse gas (GHG) emissions in the transportation sector. For this reason, in recent years, many European policies has tried to promote biofuels production and consumption. However, some concerns on the actual sustainability of biofuels have arisen. In particular, scientific studies have pointed out that additional emissions from indirect land-use change (iLUC) could cancel out biofuels benefits on climate change. Fueled by these concerns, the objective of this dissertation is to forecast the global economic and environmental consequences of an increase in European biodiesel consumption from 2001 to 2020 levels, applying the parameters established by the EU RE Directive and verify if the sustainability criteria imposed by the RED itself will be satisfied. For this purpose, I used the GTAP-BIO general equilibrium model, a model capable of analyzing the linkages between biofuels, agriculture, international trade, and the environmental consequences in terms of land-use change and greenhouse gas (GHGs) emissions. The results of the simulation confirm the already strong concerns on the sustainability of first generation biofuels brought to light by other scientific studies. The demand of biodiesel in Europe after the implementation of the RED targets is so high that the EU needs to import heavily biodiesel feedstock from other regions and this is one of the causes which entails a welfare loss. Additionally, the increase in biodiesel consumption in the European Union entails a diversion of intermediates products and factor endowments from other sectors, in particular for those sectors that compete for land. The decrease in supply for food and feed crops (which are substituted by fuel crops) drives their prices (and the relative output prices i.e. food/feed) to go up. The conflict between food and biofuel sectors is also the driving force for the indirect land use change (iLUC), which is a market-mediated effect, since the price increase creates incentives to convert areas formerly not used for food production (i.e. forests and pasture) into agricultural land. We estimate that most cropland conversion arises within Europe, mainly at the expense of forests. Looking at the GHG emissions triggered by these land use changes, the results suggest a total emission of 168 gCO2/MJ per year over 20 years of biodiesel production, which would mean that the GHG reduction requirements established by the policies could not be fulfilled.

Contemporary debates about the conservation of natural ecosystems and resources owe most of their influence to the rise of sustainable development, or, sustainability. Since its inception, ‘sustainability’ has become the dominant paradigm for addressing global ecological problems, as well as a strong motivator for changing patterns of behaviour at the level of individual people. The World Commission on Environment and Development (WCED) introduced this framework into global proenvironmental discourse in 1987, and it has since been the source of many debates and discussions within and between academic disciplines. One of the central issues has been the opposition between agency and structure. This is the problem of whether to appeal to agency (theories of individual behaviour change) or structure (theories of social practice) when addressing global environmental problems, as these fields are generally characterised as necessarily opposed to one another. However, each of them at least conceives of a particular kind of agency, meaning that both make an appeal to ‘the individual’ in one way or another. The ultimate aim of this thesis, then, is to reconfigure the way in which individual people are framed by and thus implicated in contemporary discussions about sustainability. In order to do this, I will be drawing heavily on Pierre Bourdieu’s (1984) concept of the ‘cultural intermediary,’ as well as Stuart Hall’s (cf. Grossberg, 1986) theory of ‘articulation.’ I propose a framework that characterises proenvironmental groups as ‘intermediaries,’ as each of these groups acts as a ‘mediator’ or ‘point of articulation’ between the structural dimensions of sustainability and the individual people that they address. I will analyse this framework by appealing to two close studies of two different intermediaries: Greenpeace, and its ‘Save the Reef’ campaign, and Sydney’s Inner West Council, and its ‘Home Eco Challenge.’

Public awareness of environmental problems and the need to work towards their solution have been heightened at international conferences for over two decades.Knowledge of the range of environmental perspectives and attitudes, and understanding the reasons for them, are important requirements for decision-making when dealing with global environmental issues. It is argued that culture may impact on environmental views and attitudes may shape worldwide views that give rise to them.In this study, Australian, Maldivian and Indonesian trainee teacher communities served as sources of data to examine the influence of culture on environmental attitudes. The three communities examined viewed the term 'environment' differently, and that was one reason for different environmental attitudes being exhibited.It was also found that knowledge about environments was obtained from different sources, and some individuals and communities exhibited both pro-New Environmental Paradigm and pro-Human Exemptionalist Paradigm views simultaneously. This is inconsistent with a western view of environmentalism. The findings have implications for environmental education curricula and the negotiation of global environmental issues.

A 2°C increase in global mean temperature (ΔTg) has been widely adopted as a benchmark for dangerous climate change. However, there has been a lack of research into the implications of 2°C, or any other degree of warming, for Africa. In this thesis changes in African temperature and precipitation associated with 1°C, 2°C, 3°C, 4°C, and beyond are investigated for the first time, using output from 350 climate model experiments: a collection of simulations from international modelling centres (CMIP3), two Perturbed Physics Ensembles (PPEs), and a group of five regional models. The models project temperature and precipitation anomalies which increase in magnitude and spatial extent as global temperature rises, including a wet signal in East Africa, and drier conditions for African rainforests. The models consistently show that the evolution of change with global warming is gradual, even at 4°C and beyond; but the amplitude and direction of precipitation change at each ΔTg increment vary between models and between datasets. The PPEs project precipitation signals which are not represented by CMIP3, in particular a large drying (>0.5 mm day-1 °C-1) of western Africa. There are also important differences between global and regional models, especially in southern and West Africa (>1 mm day-1). Analysis of atmospheric circulation responses suggests that the higher resolution projections are no more credible in this case. Some of the variation between models can be understood as the result of untrustworthy simulations, leading to constraints on the PPEs, and casting doubt on the strong drying of west Sahel; but model evaluation is found to be limited by observations in the case of the Congo Basin. The implications of global warming are different depending on which models are consulted. The findings emphasise that caution should be exercised in the application of climate model data to inform mitigation debates.

The aim of this thesis is to investigate efforts to transform global environmental change research through co-design and co-production (involving non-academic actors in research governance and conduct). Social scientific work to date on this topic has largely taken an evaluative perspective, outlining challenges of and guidelines for co-production on the ground. By contrast, there is little work on how co-production is conceptualised and put into practice through (international) research governance. Yet institutions aiming to govern research are significant arbiters of meaning and power; their efforts to change research are worthy of investigation. The thesis is based on a qualitative case study of Future Earth, a major international research initiative on global environmental change (GEC) and sustainability. Future Earth is unique in its ambition to internationally coordinate and co-design/co-produce new GEC/sustainability research at a global scale. The study is grounded in co-productionist, interpretive science and technology studies, drawing on ideas about political imaginaries of science and experimental approaches to engagement. It is based on thematic analysis of data from documents, interviews, focus groups and observation of Future Earth’s emergence and development between 2010 and 2015. The analysis suggests that visions of Future Earth were ambitious, diverse and sometimes ambiguous, evoking two potential institutional forms: a unified, cohesive ‘flagship’, or a ‘rich tapestry’ of varied initiatives. Ambiguity persisted in how co-production and related concepts were understood, with varying definitions motivated by different rationales for increased (or limited) involvement of non-academic stakeholders, from ensuring relevance to democratising expertise to preserving the objectivity or independence of science. These notions of appropriate engagement were underpinned by disparate conceptions of the value of research (as a service to society, site of democratic deliberation, or public good), reproducing (and challenging) established models of science and democracy. The thesis argues that, from an experimental perspective, this ambiguity in visions of (co-production in) Future Earth can be seen to enable flexibility and allow differences to co-exist. This might require new, perhaps radical, thinking about how to organise, conduct and value research and its outcomes, with an increased emphasis on fostering, appreciating and productively working with diversity and institutional indeterminacy.

The potential for an adaptive response to global climatic change was evaluated for an annual C$ sb3$ weed, Brassica juncea, by performing a selection on fecundity for eight generations. During the selection, atmospheric carbon dioxide and temperature were gradually increased from current levels (370 $ rm mu L cdot L sp{-1}$ CO$ sb2$, 20$ sp circ$C) to conditions predicted during the next century by climate models (650 $ rm mu L cdot L sp{-1}$ CO$ sb2$, 23.6$ sp circ$C) including heat stress events at 32$ sp circ$C/26$ sp circ$C day/night), At the end of the selection, a reciprocal transplant experiment was conducted to identify genetic differences between control selection lines of plants and those selected under increasing CO$ sb2$ and temperature. I observed a genetic adaptation of early vegetative growth elevated CO$ sb2$ and temperature, which resulted in to 63% more biomass and 11% higher photosynthetic rates. Reproductive biomass, however, was decreased during the selection, mainly due to temperature stress, which disrupted flower development and induced strong maternal effects, counteracting the selection on fecundity.

Includes bibliographical references (leaves 106-111).The Breede River catchment in the South Western Cape is already under pressure for its water resources due to its supporting a variety of different land uses. The predominant land use in this catchment is agriculture, which demands the majority of river water for irrigation. The Department of Water Affairs and Forestry are currently investigating the future demand for water from the river, in this respect it is important to know what effect climate change will have on the change in river flow. Self Organising Maps (SOMs) are used to identify changes in the circulation systems contributing to the rainfall of the region and from this the potential change is assessed for the Breede River flow under future climate change. It is assessed that the runoff in the Breede River is expected to change under all the models of ECHAM4, CSIRO and HadAM. The magnitude of this alteration is calculated by using the change in the SOM node frequencies between the present and the future data. This is then subtracted from the present runoff data supplied by DWAF. A source of runoff decrease in the future is agricultural irrigation. The increase in irrigation under climate change is determined by inserting future climate data into an agricultural model. Once the increased amount of water used in irrigation is determined, it is subtracted from the projected future runoff. From this it is determined whether the river will be ecologically sustainable under climate change.

Анотація:
Includes bibliographical references.Changes to global climate patterns, as predicted by many climatologists, will impact on ecosystems in numerous ways. The nutrient-rich waters of marine upwelling environments enable prolific plankton growth, which in turn supports vast shoals of pelagic fish. The nutrient supply is dependent on the strength and direction of winds, which govern the upwelling process as well as turbulence. A change in climate may thus affect the food supply and feeding conditions required by pelagic fish populations. This thesis investigates predicted changes in wind patterns in the southern Benguela system and assesses how these changes may impact on the recruitment of the Cape anchovy, Engraulis capensis. A general circulation model (NCAR Climate System Model) is used to compare a future simulation under double C02 conditions with a simulation of the present day wind regime. Climate change effects on anchovy in the other main upwelling systems, off the coasts of California, Peru and Morocco are also examined. Wind speeds and turbulence off the Agulhas Bank in the southern Benguela system are expected to remain suitable and potentially become even more conducive to spawning in the future. The results show similar mean wind speeds to present day values, a decrease in mean turbulence, a decrease in the frequency of extreme wind speeds and a decrease in the frequency of extreme turbulence during the anchovy spawning season (i.e. September-February). An increase in Lasker events is expected at the Eastern Bank Grid Cell, which suggests that this area may become the preferred spawning habitat in the future. The Cape Town Grid Cell also shows suitable conditions in the future simulation for anchovy spawning and may thus become an alternative spawning location. The West Coast shows an increase in alongshore wind stress and thus an increase in upwelling in the future simulation from November - February. This is likely to increase planktonic food availability and ultimately anchovy recruitment. Future simulations from the Climate System Model show that the upwelling systems off the coasts of California, Peru and Morocco are likely to continue supporting anchovy spawning and may become even more suitable in terms of wind and turbulence regimes.

This synthesis article joins the authors of the special issue "Gender perspectives in resilience, vulnerability and adaptation to global environmental change" in a common reflective dialogue about the main contributions of their papers. In sum, here we reflect on links between gender and feminist approaches to research in adaptation and resilience in global environmental change (GEC). The main theoretical contributions of this special issue are threefold: emphasizing the relevance of power relations in feminist political ecology, bringing the livelihood and intersectionality approaches into GEC, and linking resilience theories and critical feminist research. Empirical insights on key debates in GEC studies are also highlighted from the nine cases analysed, from Europe, the Americas, Asia, Africa and the Pacific. Further, the special issue also contributes to broaden the gender approach in adaptation to GEC by incorporating research sites in the Global North alongside sites from the Global South. This paper examines and compares the main approaches adopted (e.g. qualitative or mixed methods) and the methodological challenges that derive from intersectional perspectives. Finally, key messages for policy agendas and further research are drawn from the common reflection.

Satellite geodesy plays an important role in earth observation. This dissertation presents three applications of satellite geodesy in environmental and climate change. Three satellite geodesy techniques are used: high-precision Global Positioning System (GPS), the Gravity Recovery and Climate Experiment (GRACE) and Interferometric Synthetic Aperture Radar (InSAR). In the first study, I use coastal uplift observed by GPS to study the annual changes in mass loss of the Greenland ice sheet. The data show both spatial and temporal variations of coastal ice mass loss and suggest that a combination of warm atmospheric and oceanic condition drove these variations. In the second study, I use GRACE monthly gravity change estimates to constrain recent freshwater flux from Greenland. The data show that Arctic freshwater flux started to increase rapidly in the mid-late 1990s, coincident with a decrease in the formation of dense Labrador Sea Water, a key component of the deep southward return flow od the Atlantic Meridional Overturning Circulation (AMOC). Recent freshening of the polar oceans may be reducing formation of Labrador Sea Water and hence may be weakening the AMOC. In the third study, I use InSAR to monitor ground deformation caused by CO2 injection at an enhanced oil recovery site in west Texas. Carbon capture and storage can reduce CO2 emitted from power plants, and is a promising way to mitigate anthropogenic warming. From 2007 to 2011, ~24 million tons of CO2 were sequestered in this field, causing up to 10 MPa pressure buildup in a reservoir at depth, and surface uplift up to 10 cm. This study suggests that surface displacement observed by InSAR is a cost-effective way to estimate reservoir pressure change and monitor the fate of injected fluids at waste disposal and CO2 injection sites.

Includes bibliographical referencesDrought is one of the natural hazards that threaten the economy of many nations, especially in Southern Africa, where many socio-economic activities depend on rain-fed agriculture. This study evaluates the capability of Regional Climate Models (RCMs) in simulating the Southern African droughts. It uses the Standardized Precipitation-Evapotranspiration Index (SPEI, computed using rainfall and temperature data) to identify 3-month droughts over Southern Africa, and compares the observed and simulated drought patterns. The observation data are from the Climate Research Unit (CRU), while the simulation data are from 10 RCMs (ARPEGE, CCLM, HIRHAM, RACMO, REMO, PRECIS, RegCM3, RCA, WRF, and CRCM) that participated in the Regional Climate Downscaling Experiment (CORDEX) project. The study also categorizes drought patterns over Southern Africa, examines the persistence and transition of these patterns, and investigates the roles of atmospheric teleconnections on the drought patterns. The results show that the drought patterns can occur in any season, but they have preference for seasons. Some droughts patterns may persist up to three seasons, while others are transient. Only about 20% of the droughts patterns are induced solely by El Niño Southern Oscillation (ENSO), other drought patterns are caused by complex interactions among the atmospheric teleconnections. The study also reveals that the Southern Africa drought pattern is generally shifting from a wet condition to a dry condition, and that the shifting can only be captured with a drought monitoring index that accounts for temperature influence on drought. Only few CORDEX RCMs simulate the Southern African droughts as observed. In this regard, the ARPEGE model shows the best simulation. The best performance may be because the stretching capability of ARPEGE helps the model to eliminate boundary condition problems, which are present in other RCMs. In ARPEGE simulations, the stretching capability would allow a better interaction between large and small scale features, and may lead to a better representation of the rain producing systems in Southern Africa. The results of the study may be applied to improve monitoring and prediction of regionally-extensive drought over Southern Africa, and to reduce the socio-economic impacts of drought in the region.

Includes bibliographical referencesThis thesis explores the relationship between the commercial insurance industry, global environmental change (GEC) and what Beck (1992; 1999) termed the 'risk society'. In recent decades, there have been growing concerns that many of the risks impacting contemporary society have undergone fundamental changes. Many of these risks are increasingly being linked to the unintended consequences of humankind's remarkable progress in science and technology, and have been described as debounded, given that they so often transcend both geographical and temporal boundaries (Beck 1992). Within the risk society, the commercial insurance industry - which relies on statistical (actuarial) analysis to help it assess and manage its risk exposure - has been described as demarcating the frontier barrier between bounded (i.e. insurable) and debounded (i.e. uninsurable) risk. However, this claim has been a highly contested one, leading to calls for more empirical data to help clarify how commercial insurance is actually responding under conditions of uncertainty. Of all the debounded risks, GEC has emerged as one of the risk society's most recognisable. Now understood to be a result of the anthropogenic emission of greenhouse gasses, particularly since the onset of the industrial revolution, its impacts have risen so sharply in recent decades that it has prompted claims that Earth has moved away from the era of the Holocene and into the Anthropocene (Crutzen 2002). Given that at least 40% of the cost of environmental catastrophes is now borne by commercial insurance, GEC provides an excellent opportunity to gain a deeper understanding of how the industry is responding to debounded risk at the risk society's frontier barrier. Early commentators suggested that the commercial insurance industry would be well motivated to respond proactively to GEC, by taking a more mitigative approach to managing its drivers at both the global and local levels. However, the industry, so far, has been described as more adaptive of its own business activities than mitigative. This raises questions about whether such claims are true across all three of the insurance industry's activities - as risk carriers, risk managers and as investors, why they have responded in such ways, and what implications this has for broadening our understanding of the complex relationship between commercial insurance, debounded risk and the risk society's frontier barrier. To consider these questions, a collective case study was undertaken with a variety of commercial insurance companies, re-insurers, asset managers, clients, brokers, industry associations and regulators across South Africa, Germany, Switzerland, the United Kingdom and Belgium. The research identified how commercial insurers have indeed responded more by adaptation of their business activities than mitigation of the drivers of GEC. This is mainly through the use of defensive underwriting to help them manage their exposure. However, the research extends this analysis by highlighting some of the nuances of the industry's response. This includes its focus on centralisation, the influence of the existing paradigm framing its understanding of risk, and by highlighting the irony that the area of insurers' activities, initially believed to be most suited for responding to GEC (i.e. their investment portfolios), have, in practice, been the area recording the least response. In exploring why this is so, the study draws on understandings of the Anthropocene to argue that commercial insurers are finding their existing risk assessment tools progressively out-dated in a world where risk is no longer as predictable as it once was. This is further compounded by increasingly plural access to the risk society's science and technologies, which, in some instances, are undermining the role commercial insurance plays as society's primary financial risk manager. This raises questions around the role commercial insurance plays in demarcating the risk society's frontier barrier which, ultimately, has far broader implications for why so many of society's institutions are struggling to adapt to risk in the 21st Century.

Uttryck som återvinning, energismarta lösningar, förnyelsebar elproduktion ochhållbar avfallshantering får alltmer uppmärksamhet.

Dessutom är det oftast de som både har pengar och makt attverkligen påverka utgången av konsumerandet.Något annat som blir allt vanligare bland företagens arbetsmetoder är att bedriva sinverksamhet i projektform. I vissa fall har själva företagsidén blivit att man nischat sig helt tillatt skapa och leda projekt åt andra företag, så kallade managementkonsulter.Detta visar alltså flera åtskiljda växande intressen på frammarsch, men bedrivs de utan någrasamband? Företagens befintliga miljöarbete består mestadels i att sätta upp mål vilkaförhoppningsvis kan leda till någon form av certifiering eller intyg på att en viss nivå haruppnåtts. Dessa miljömål har ofta bristfälliga uppföljningar samtidigt som det finns en uppsjöav olika rapporteringsmodeller och certifieringar vilket försvårar kontinuerlig uppdatering avaktuell status inom området.Denna uppsats är gjord på uppdrag av företaget CGI Sweden vilket i vår uppstartsfas hetteLogica.

Humanity currently faces an existential crisis: anthropogenic climate change. In order to guarantee our survival on a stable planet, immediate mitigation and adaption strategies must be implemented. However, institutions are failing to live up to the task and a concrete action plan is currently non-existent, as climate governance struggles with fragmentation, commitment, and challenges posed by neoliberalism. Since the top-down approach is insufficient, extra-institutional actors are arising as leaders for the environmental agenda. This study narrows down on Greta Thunberg and assesses her capacity in leading the climate movement. The applicability of frame theory (Benford and Snow, 2000) will be tested to understand the mobilisation potential of Greta’s discourse. The main focus of this examination is to analyse how Greta has used diagnostic, prognostic, and motivational collective action frames in order to place the limelight on the seriousness of climate change and correspondingly how this has led to civil society mobilisation. Through a discourse analysis of her speeches, it was discovered that the framing perspective plays a role in meaning construction for the movement.
