Indigenous people often rely on natural resources for their livelihoods. This reliance increases their vulnerability towards the impacts of climate change, and coping with increased climate variability is a significant challenge for such communities. This research, conducted among the Sa’ban tribe of Long Banga in interior Sarawak, Malaysia, explored observations of local climate change, climate change impacts and tribal adaptation strategies. The results show that drought, wildfires and uncertain weather conditions are the Sa’ban’s primary concerns. However, the tribe have demonstrated their adaptation strategies through the use of traditional ecological knowledge (TEK).

The history of biosystematics research and its impacts on climate goes before political ramifications. Climate change is altering the environments and likely to result in changes in the distribution of species, flowering times; migrate and adapt to the new environmental conditions; or extinction. Adaptive capacity is the ability of the plants to adapt to the impacts of climate change. Adaptation process is going in nature through phenotypic plasticity, natural selection or migration or polyploidization. The options are not mutually exclusive. Phenotypic plasticity may be the most efficient way of adaptation to a new environment. Polyploidization may increase tolerance to diverse ecological conditions and the high incidence of polyploidy in plants indicates its adaptive significance. Population having polyploid pillar complex is a good backup support towards microevolution and speciation, a mode of adaptation. The paper discusses about these biosystematics approaches towards adaptation to new environmental conditions resulting from climate change. It also discusses about the role of taxonomists under the changed circumstances. It is evident from the review that a set of biosystematics data along with other ecological and conservation information needs to be included in Flora and Monographs. It reveals that it was as far as worked out at the Paris Botanical Congress 1954 and put up by Stebbins in a series of proposals, termed as “Stebbins’ Ten Points” that needs further enrichment.

Planning for adaptation to climate change requires regionally relevant information on rising air and ocean temperatures, sea levels, increasingly frequent and intense storms, and other climate-related impacts. However, in many regions there are limited focused syntheses of the climate impacts, risks, and potential adaptation strategies for coastal marine areas and sectors. We report on a regional assessment of climate change impacts and recommendations for adaptation strategies in the NE Pacific Coast (British Columbia, Canada), conducted in collaboration with a regional planning and plan implementation partnership (Marine Plan Partnership for the North Pacific Coast), aimed at bridging the gaps between climate science and regional adaptation planning. We incorporated both social and ecological aspects of climate change impacts and adaptations, and the feedback mechanisms which may result in both increased risks and opportunities for the following areas of interest: “Ecosystems”, “Fisheries and Aquaculture”, “Communities”, and “Marine Infrastructure”. As next steps within the region, we propose proactive planning measures including communication of the key impacts and projections and cross-sectoral assessments of climate vulnerability and risk to direct decision-making.

Full textAbstract:
Abstract Infectious diseases result from the interactions of host, pathogens, and, in the case of vector-borne diseases, also vectors. The interactions involve physiological and ecological mechanisms and they have evolved under a given set of environmental conditions. Environmental change, therefore, will alter host-pathogen-vector interactions and, consequently, the distribution, intensity, and dynamics of infectious diseases. Here, we review how climate change may impact infectious diseases of aquatic and terrestrial wildlife. Climate change can have direct impacts on distribution, life cycle, and physiological status of hosts, pathogens and vectors. While a change in either host, pathogen or vector does not necessarily translate into an alteration of the disease, it is the impact of climate change on the interactions between the disease components which is particularly critical for altered disease risks. Finally, climate factors can modulate disease through modifying the ecological networks host-pathogen-vector systems are belonging to, and climate change can combine with other environmental stressors to induce cumulative effects on infectious diseases. Overall, the influence of climate change on infectious diseases involves different mechanisms, it can be modulated by phenotypic acclimation and/or genotypic adaptation, it depends on the ecological context of the host-pathogen-vector interactions, and it can be modulated by impacts of other stressors. As a consequence of this complexity, non-linear responses of disease systems under climate change are to be expected. To improve predictions on climate change impacts on infectious disease, we suggest that more emphasis should be given to the integration of biomedical and ecological research for studying both the physiological and ecological mechanisms which mediate climate change impacts on disease, and to the development of harmonized methods and approaches to obtain more comparable results, as this would support the discrimination of case-specific versus general mechanisms.

As part of numerous efforts on adapting to climate change in Nepal, an approach of Ecosystem-based Adaptation (EbA) is being demonstrated in the Panchase Mountain Ecological Region (PMER). Partners under the project entitled Ecosystem-based Adaptation in Mountain Ecosystems in Nepal have been implementing activities to reduce vulnerability of the PMER to climate change and enhance resilient capacity of communities and ecosystems in the region to cope with adverse impacts of climate change already being witnessed. This article places focus on the process of EbA planning and preliminary lessons learned through the project activities in particular at local and ecological level. Reflection and suggestion on EbA planning presented in the article is expected to help all stakeholders in the Himalayan region and beyond design and implement future climate change adaptation activities to be more effective and efficient while empowering local communities and ensuring social, economic and environmental sustainability.

Full textAbstract:
Climate Change 1995 is a scientific assessment that was generated by more than 1 000 contributors from over 50 nations. It was jointly co-ordinated through two international agencies; the World Meteorological Organization and the United Nations Environment Programme. The assessment was completed by the Intergovernmental Panel on Climate Change (IPCC) with a primary aim of reviewing the current state of knowledge concerning the impacts of climate change on physical and ecological systems, human health, and socioeconomic factors. The second aim was to review the available information on the technical and economic feasibility of the potential mitigation and adaptation strategies.

Full textAbstract:
The Sundarbans is the world’s largest coastal river delta and the largest uninterrupted mangrove ecosystem. A complex socio-ecological setting, coupled with disproportionately high climate-change exposure and severe ecological and social vulnerabilities, has turned it into a climate hotspot requiring well-designed adaptation interventions. We have used the fuzzy cognitive maps (FCM)-based approach to elicit and integrate stakeholders’ perceptions regarding current climate forcing, consequent impacts, and efficacy of the existing adaptation measures. We have also undertaken climate modelling to ascertain long-term future trends of climate forcing. FCM-based simulations reveal that while existing adaptation practices provide resilience to an extent, they are grossly inadequate in the context of providing future resilience. Even well-planned adaptations may not be entirely transformative in such a fragile ecosystem. It was through FCM-based simulations that we realised that a coastal river delta in a developing nation merits special attention for climate-resilient adaptation planning and execution. Measures that are likely to enhance adaptive capabilities of the local communities include those involving gender-responsive and adaptive governance, human resource capacity building, commitments of global communities for adaptation financing, education and awareness programmes, and embedding indigenous and local knowledge into decision making.

Full textAbstract:
Much of the climate discourse of today is held the reduction of greenhouse gases (GHG) emissions and reducing humanity’s ecological footprint on Earth. However, as climate change is already impacting our planet, adaptation measures to climate change are also required. Rising temperatures, the multiplication of intense precipitation events and related pluvial and river floods, drought events and water scarcity, the increase of frequency of wildfires represent a few of the multiple climate change impacts that governments and citizens have to deal with.
For ecological reasons, climate change affects areas very differently based on geographic location and urban centers represent climate ‘hotspots’ as areas with high vulnerability. As a consequence of this, cities and towns play a crucial role in tackling climate change effects.
The aim of this essay is to analyze the legal aspects of climate change adaptation set by local governments to prevent and manage damages related to climate-related risks. More in detail, after determining the international, European and national legal framework on adaptation, the purpose of the article is to identify the legal instruments used by local administrations to develop adaptation measures. In particular, the analysis focuses on the legal aspects related to three dimensions of local adaptation: urban greening as a nature-based solution for heat waves risks; the management of water-related risks; the civil protection planning function of municipalities. Considering the impacts of the mainstreaming process on planning tools, special attention is directed towards the integration and coordination issue between the different urban and sectoral planning instruments required by the Italian multi-level governance legal system.

The impacts of climate change have caused the changes in temperature, seasons, rainfall, sea level, storms, floods, drought, and extreme temperatures. Communities that are at the forefront to get the impacts of climate change are coastal and small island communities, one of which is tourism places. Karimunjawa is as one of areas that get the impact of the climate change. However, in a period of seven years, the development of tourism in Karimunjawa village has experienced a large increase as evidenced by the increasing number of foreign and domestic tourists. This paper aims to describe the phenomenon of adaptation and livelihood resilience in tourism-based villages on Karimunjawa Island as a socio-ecological system by applying the adaptive cycle as an exploratory diagnostic, dynamics, and direction tool of change in the socio-ecological system. This research utilizes a qualitative analysis of the livelihood adaptation strategies adopted by the informants. From the result of this study, it can be perceived that strategies to strengthen the resilience of communities, and especially the poor, must be based on a combination of the most effective measurable and increased commitment to the asset base and measures to provide better services. Therefore, local adaptation strategies are aimed at building livelihood resilience are very important because they will greatly affect the ability of communities to face the impacts of climate change. Tourism development policies in rural areas are very effective in building adaptation capacity and livelihood resilience of local communities. Local government institutions, particularly provincial governments, play an important role in fostering an enabling environment for local adaptation.

Climate change and flooding in Asian cities pose great challenges to the environmental and human security of the population and their governance systems. This paper examines the intersections of ecological-environmental and social vulnerability and the adaptive responses of urban poor communities and commercial-industrial establishments in Metro Manila to floods and other climate change-related effects, such as storm surges and sea-level rise (SLR). These weaken the communities’ ecological-environmental systems, threaten the well-being and security of the people and strain the resources of city governments. Disaggregating the ecological-environment vulnerabilities of a city/community according to specific places/spaces (or place-based vulnerabilities) that lead also to variable patterns among different groups (e.g., gender, income group, sector) of adaptive responses to flooding. Drawing a systematic sample of urban poor households and industrial-commercial establishments along the Pasig-Marikina River Basin of Metro Manila, this study utilised household surveys, key informant interviews, focus group discussions (FGD) and secondary data sources, in analysing the sources of their vulnerability and adaptive responses. Existing studies generally focus on the vulnerability and adaptation of urban-rural populations and do not highlight the interaction of place-based vulnerabilities with sector-specific vulnerabilities that reconfigure flood impacts and responses among the urban poor communities and commercial-industrial establishments during and after floods. In particular, poor and female-headed households residing in highly degraded environments or places/spaces within and across urban poor communities suffered higher damages and losses compared to better-off households and establishments. The interaction of these drivers of vulnerability further heightens and compromises the environmental and human security needs of poor people, their communities and those in the private sector that local/national government agencies need to respond.

AbstractResilience thinking – an approach for understanding and managing change – is increasingly central to climate change adaptation law and policy. Yet the influence of adaptation law and policy on the distribution of climate impacts is often overlooked in studies of socio-ecological resilience to climate change. This article demonstrates how environmental justice scholarship helps to address this gap in the literature relating to adaptation law and resilience. Drawing on existing literature, the article identifies four principles to promote resilience and justice through climate adaptation laws. Climate adaptation laws must (i) prepare for, and respond to, change; (ii) address the distributive effects of climate change and adaptation; (iii) promote participation in adaptation processes; and (iv) cross sectors and scales. Each criterion can be implemented in part through existing legal processes, but might also be further supported by incremental law reform. Developing both resilience and justice dimensions will enhance the effectiveness of adaptation laws in addressing climate impacts.

Understanding local community perceptions on impacts, causes, and responses to climate change is vital for promotion of community resilience towards climate change. This study explored local ecological knowledge (LEK) held by local communities on climate change trends and impacts in the Middle Zambezi Biosphere Reserve (MZBR), Zimbabwe. The objectives of the study were to (i) investigate local community perceptions on trends and causes of climate change, (ii) identify biophysical impacts of climate change at the local level, and (iii) explore the ecosystem-based adaptation strategies towards climate change. The study used a mixed methods approach where a household questionnaire survey (n=320), key informant interviews (n=12), and focus group discussions (n=8) were used to collect data between April 2015 and October 2016. Results from the study show that local communities have observed decreasing rainfall and increasing temperatures as key indicators of climate change. Local communities observed water scarcity, changes in vegetation phenology, livestock and wildlife mortalities, and food shortages due to drought as the major impacts on their livelihoods. LEK can contribute to adaptive management strategies that enhance resilience of socioecological systems (SES) in the face of climate change by providing information on the status and use of biophysical components of the environment and by highlighting potential local adaptation strategies that can sustain key livelihood practices.

Coastal climate change impacts challenge policy and decision makers to adopt more effective adaptation measures. The ecosystem-based management approach can shift adaptation towards a more holistic, integrated and sustainable path. However, as countries work on strategies to adapt to climate change, the questions of if and how such agendas consider and operationalise ecosystem-based management remains. As one of the world’s largest coastal countries, Brazil can have a prominent role in advancing the implementation of ecosystem-based management to coastal zones. By analysing two national Brazilian climate change adaptation institutions, this article evaluates and discusses the country’s advances in promoting climate change adaptations based on ecosystem-based management principles. Our findings show that, although Brazil has incorporated many ecosystem-based management principles to climate change adaptation at the national level, greater attention should be given to operationalizing principles related to acknowledging uncertainties, sustainability, democracy and knowledge production and application. The challenges to implement these principles mirror historical challenges of Brazilian coastal management policies, such as balancing development and conservation, promoting social participation and implementing effective social-ecological assessments and monitoring programs. Policy makers, scientists and communities should be aware of the need to strengthen ecosystem-based management principles in the current adaptation agenda in order to enhance its capacity to foster adaptation and just coastal sustainability.

Full textAbstract:
Any adaptation activity needs a reliable evidence basis for the climate itself as well as for the exposition and sensitivity of the social, economic or ecological system and its elements. This requires an assessment of recent climate impacts as well as potential future climate change impacts in order to select tailor-made adaptation measures. For a methodologically coherent assessment, the Intergovernmental Panel on Climate Change (IPCC) had introduced the requirement of a parallel modeling approach which means that demographic and socioeconomic changes are projected in parallel to the changes of the climatic system. This paper discusses a conceptual framework of a parallel modeling approach and presents its application in four case studies of climate change impact assessments in Germany, covering the national, regional and local scale. The results from the different applications prove the hypothesis that the change in sensitivity (i.e., demographic change, economic change and change in land-use patterns) often determines the magnitude of climate- and weather-related impacts in the near future significantly. The case studies, however, also show that adaptation processes have to be organized in a collaborative way, which takes the knowledge, and also the concerns of the addressees into full account. A broad mandate from all social groups is especially needed when political decisions are based on uncertain knowledge — which is the case whenever climate change impacts are assessed.

The impacts of climate change put pressure onto environmental and natural resources, which in turn increases the vulnerability of ecosystems and human communities. This makes social participation essential for biodiversity conservation. This article addresses the community perceptions of the adaptations made to climate change in the El Vizcaino Biosphere Reserve (REBIVI), in Baja California Sur (Mexico), one of the largest natural protected areas in Latin America. Workshops with local communities defined the Socio-ecological Assets for Conservation (SEACs) and prioritized the adaptation strategies and actions by multicriteria analysis. The conclusions point out that a combination of ecosystem-based adaptation (EbA) and communities-based adaptation (CbA) is the most appropriate pathway to affront the adverse impacts of climate change. Thus, a socioecological approach for land and biodiversity use planning has to be implemented if both human welfare and conservation are to be effectively promoted. The process is necessary and very important, as is the participation of the local residents in the implementation and monitoring of the adaptation actions.

A comprehensive assessment of the impacts of climate change on agro-ecosystems over this century is developed, up to 2080 and at a global level, albeit with significant regional detail. To this end an integrated ecological–economic modelling framework is employed, encompassing climate scenarios, agro-ecological zoning information, socio-economic drivers, as well as world food trade dynamics. Specifically, global simulations are performed using the FAO/IIASA agro-ecological zone model, in conjunction with IIASAs global food system model, using climate variables from five different general circulation models, under four different socio-economic scenarios from the intergovernmental panel on climate change. First, impacts of different scenarios of climate change on bio-physical soil and crop growth determinants of yield are evaluated on a 5′×5′ latitude/longitude global grid; second, the extent of potential agricultural land and related potential crop production is computed. The detailed bio-physical results are then fed into an economic analysis, to assess how climate impacts may interact with alternative development pathways, and key trends expected over this century for food demand and production, and trade, as well as key composite indices such as risk of hunger and malnutrition, are computed. This modelling approach connects the relevant bio-physical and socio-economic variables within a unified and coherent framework to produce a global assessment of food production and security under climate change. The results from the study suggest that critical impact asymmetries due to both climate and socio-economic structures may deepen current production and consumption gaps between developed and developing world; it is suggested that adaptation of agricultural techniques will be central to limit potential damages under climate change.

Agriculture the major economic and social activity in the globe. It is understood that agriculture is highly sensitive to climatic variability and likely to be affected most to predicted climate change. The fourth assessment report of Intergovernmental Panel on Climate Change (IPCC) has reconfirmed that the phenomenon of existence of climate change in recent decades is due to anthropogenic activities. It is also revealed the availability of wide array of adaptation options for agro-ecosystem to cope up with the impact of climate change. However, it is important to design more extensive adaptation strategies to reduce vulnerability of agriculture and rural poor to impacts of climate change. Climate change impacts and responses are presently observed as autonomous adaptation in the physical and ecological systems as well as in human adjustments to resource availability and risks at different spatial and trophic levels. But these strategies are not enough to reduce the current anthropogenic driven climate change, so there is a need to adopt the planned adaptation. This paper reviews the findings based on the series of studies carried across the globe on the potential adaptation strategies to alleviate the impact of climate change by improving the resilience of the agro-ecosystems. Adaptation strategies have to be in place to reduce vulnerability to climate change through developing consensus between industrialized countries and developing countries at global scale, whereas new public policies in place at national regional and local level is prudent to support adaptation research, insurances, incentives to farmers to adapt new technologies.

The impacts of climate change especially on water resources are beginning to manifest both globally and regionally. More disturbing is the fact that developing countries, particularly those in sub-Saharan Africa, are the most affected by these impacts due mainly to their high exposure, sensitivity, and low adaptive capacity. For Ghana, the general climate change has manifested in rising temperatures, declining rainfall, high extreme weather conditions, and rising sea levels. In response to these challenges, the country has developed national adaptation strategies for implementation at regional, district, community, and individual levels. Key among the strategies for reducing the impacts of climate change on the water are the conservation of water resources, improving and sustaining the quality of water, and increasing the availability of water for domestic and agricultural purposes. However, the level of vulnerability to climate change is influenced by both social and spatial factors because of the different ecological zones whose characteristics significantly influence both the physical and socio-economic dimensions of the various areas differently. Additionally, the decentralized implementation of the national climate change adaptation strategy has largely failed to achieve any significant results due to a lack of capacity on the part of the implementation partners at the various levels, as well as the overambitious nature of the strategy. A more ecologically tailored approach with an emphasis on the district and community levels is recommended for going forward. Improvements on the various components of vulnerability with regard to water management are recommended for reducing the effects of droughts.

AbstractVector-borne diseases are exceptionally sensitive to climate change. Predicting vector occurrence in specific regions is a challenge that disease control programs must meet in order to plan and execute control interventions and climate change adaptation measures. Recently, an increasing number of scientific articles have applied ecological niche modelling (ENM) to study medically important insects and ticks. With a myriad of available methods, it is challenging to interpret their results. Here we review the future projections of disease vectors produced by ENM, and assess their trends and limitations. Tropical regions are currently occupied by many vector species; but future projections indicate poleward expansions of suitable climates for their occurrence and, therefore, entomological surveillance must be continuously done in areas projected to become suitable. The most commonly applied methods were the maximum entropy algorithm, generalized linear models, the genetic algorithm for rule set prediction, and discriminant analysis. Lack of consideration of the full-known current distribution of the target species on models with future projections has led to questionable predictions. We conclude that there is no ideal ‘gold standard’ method to model vector distributions; researchers are encouraged to test different methods for the same data. Such practice is becoming common in the field of ENM, but still lags behind in studies of disease vectors.

Widespread implementation of nature-based solutions like green infrastructure, provides a multi-functional strategy to increase climate resilience, enhance ecological connectivity, create healthier communities, and support sustainable urban development. This paper presents a decision-support framework to facilitate adoption of green infrastructure within communities using the Climate Change Local Adaptation Action Model (CCLAAM) developed for this purpose. It also presents an ecosystems-based approach to bridging the gap between climate change mitigation and adaptation actions in Ontario, Canada. Green infrastructure could be a viable strategy to address multiple climate change impacts and support the implementation of the UN Sustainable Development Goals (SDGs).

The eco-system in the Qinghai-Tibet Plateau (QTP) is extremely fragile, and highly vulnerable to climate change. Knowledge of the changes in the ecological conditions is vital to mitigate the impact of climate change. In this study, we investigated the trend of ecological conditions of the QTP using the remotely sensed ecological index (RSEI), which is the first PCA (principal component analysis) axis of the four indexes derived from the MODIS (Moderate resolution Imaging Spectroradiometer) images captured in the growing season of 2000–2020. The four indexes, i.e., NDVI (normalized difference vegetation index), heat (land surface temperature, LST), wetness (tasseled cap wetness index, WET) and dryness (normalized difference impervious surface index, NDBSI), were calculated on the Google Earth Engine platform. Using land use cover change (LUCC) data, long-term meteorological records and the supplementary annual livestock production, we explored the drivers of spatiotemporal changes in the RSEI. The results show the following points: (1) the ecological conditions of the QTP have remarkable spatiotemporal variations. There were two ecological degradation periods, one of them occurred in the central region during 2005–2010, mainly attributed to the rising temperatures and decreasing precipitation. The other occurred during 2015–2020, driven primarily by overgrazing in the southwest. From 2000 to 2005, it was a period of rapid ecological restoration in the ecologically fragile northeast region. (2) The contribution rate of pc1 was stable at 60%, while the contribution rate of pc2 remained below 40%, indicating that pc1 demonstrated most of the characteristics of the four indexes. The correlation coefficients between NDVI and WET with pc1 are both positive, while LST and NDBSI have negative correlation coefficients, i.e., negative effects. This is consistent with the actual situation. (3) Overgrazing caused grass degradation in the southwest area of the QTP, which might be the main reason for the poor ecological conditions (i.e., low RSEI value) during 2015–2020. (4) Temperature and precipitation showed an increasing trend during the study period. A warmer and wetter climate is expected to have profound impacts on the ecosystems in QTP and practices should be concentrated on identifying climate-sensitive ecosystem components and designating adaptative options.

AbstractMany rural communities in the western United States are surrounded by public lands and are dependent on these landscapes for their livelihoods. Climate change threatens to affect land-based livelihoods through both direct impacts and public land agency decision-making in response to impacts. This project was designed to understand how Bureau of Land Management (BLM) permittees, including ranching and recreation-based businesses in Colorado, are vulnerable to both climate change and management responses and how permittees and the BLM are adapting and could adapt to these changes. We conducted 60 interviews in two BLM field offices to gather permittee and agency employees’ observations of change, impacts, responses, and suggestions for adaptive actions. Data suggested that permittees are dependent on BLM lands and are sensitive to ecological and management changes and that current management policies and structures are often a constraint to adaptation. Managers and permittees are already seeing synergistic impacts, and the BLM has capacity to facilitate or constrain adaptation actions. Participants suggested increased flexibility at all scales, timelier within-season adjustments, and extension of current collaborative efforts to assist adaptation efforts and reduce impacts to these livelihoods.

The research presented in this paper studied the functional linkages between risk and adaptation appraisal and the psychosocial discourse variables that influence the outcomes for adaptive capacity of island communities to the impact of climate change. Qualitative data was gathered from focus group discussions and semi-structured interviews in five, purposively selected communities of the Maldives, from June to December 2015. The findings showed that risk appraisal was enhanced by direct experiences encountered and social construction of climate change. We found that a negative appraisal of adaptation arises due to lack of resources, fatalism and wishful thinking. While objective adaptive capacity was low, a higher subjective adaptive capacity was observed. The results also showed that people’s ecological knowledge of the reef-island systems depended on their livelihood practices, and that changes to modern livelihood practices can lead to loss of deep ecological knowledge and lead to dependency on external data only for adaptation. The findings add to the research on importance of meanings, ideas, behaviours and values of people, and the agency of such variables for positive appraisal of risks and adaptation.

The traditional knowledge of indigenous people is often neglected despite its significance in combating climate change. This study uncovers the potential of traditional ecological knowledge (TEK) from the perspective of indigenous communities in Sarawak, Malaysian Borneo, and explores how TEK helps them to observe and respond to local climate change. Data were collected through interviews and field work observations and analysed using thematic analysis based on the TEK framework. The results indicated that these communities have observed a significant increase in temperature, with uncertain weather and seasons. Consequently, drought and wildfires have had a substantial impact on their livelihoods. However, they have responded to this by managing their customary land and resources to ensure food and resource security, which provides a respectable example of the sustainable management of terrestrial and inland ecosystems. The social networks and institutions of indigenous communities enable collective action which strengthens the reciprocal relationships that they rely on when calamity strikes. Accordingly, the communities maintain their TEK through cultural festivals and oral traditions passed from one generation to another. TEK is a practical tool that helps indigenous communities adapt to climate risks and promotes socio-ecological resilience, which upholds social empowerment and sustainable resource management.

Full textAbstract:
The challenges that climate change poses for marine ecosystems are already manifesting in impacts at the species, population, and community levels in Australia, particularly in Tasmania and tropical northern Australia. Many species and habitats are already under threat as a result of human activities, and the additional pressure from climate change significantly increases the challenge for marine conservation and management. Climate change impacts are expected to magnify as sea surface temperatures, ocean chemistry, ocean circulation, sea level, rainfall, and storm patterns continue to change this century. In particular, keystone species that form the foundation of marine habitats, such as coral reefs, kelp beds, and temperate rocky reefs, are projected to pass thresholds with subsequent implications for communities and ecosystems. This review synthesises recent science in this field: the observed impacts and responses of marine ecosystems to climate change, ecological thresholds of change, and strategies for marine conservation to promote adaptation. Increasing observations of climate-related impacts on Australia’s marine ecosystems—both temperate and tropical—are making adaptive management more important than ever before. Our increased understanding of the impacts and responses of marine ecosystems to climate change provides a focus for “no-regrets” adaptations that can be implemented now and refined as knowledge improves.

Abstract Drought is a natural part of the historical climate variability in the northern Rocky Mountains and high plains region of the United States. However, recent drought impacts and climate change projections have increased the need for a systematized way to document and understand drought in a manner that is meaningful to public land and resource managers. The purpose of this exploratory study was to characterize the ways in which some federal and tribal natural resource managers experienced and dealt with drought on lands managed by the U.S. Department of the Interior (DOI) and tribes in two case site examples (northwest Colorado and southwest South Dakota) that have experienced high drought exposure in the last two decades. The authors employed a social–ecological system framework, whereby key informant interviews and local and regional drought indicator data were used characterize the social and ecological factors that contribute to drought vulnerability and the ways in which drought onset, persistence, severity, and recovery impact management. Results indicated that local differences in the timing, decisions, and specific management targets defined within the local social–ecological natural resource contexts are critical to understanding drought impacts, vulnerabilities, and responses. These findings suggest that manager-defined social–ecological contexts are critically important to understand how drought is experienced across the landscape and the indices that are needed to inform adaptation and response strategies.

Abstract. This special issue (SI) shows that environmental justice perspectives are especially useful for analysing current socio-ecological conflicts. These perspectives help to bridge epistemological and ontological gaps in inter- and transdisciplinary settings and promote normative and justice-oriented discussions on environmental struggles within and beyond the academy. Currently, the following two interrelated environmental crises and their impacts regularly make headlines: climate change and the impacts of the unsustainable use of the oceans. Still, for a large part of the global population – not only but especially in the Global North – both crises remain abstract, mainly becoming visible through news coverage of plastic waste in the oceans, storm surges and droughts, and through documentaries on sea-level rise and the destruction of ecosystems. However, the destruction of marine and coastal habitats and the effects of climate change are increasingly affecting people's daily lives. The effects of climate change, pollution, and marine resource overuse are creating serious disruption to livelihoods and leading to new socio-ecological conflicts and new claims. This SI aims to reflect and explore climate and marine narratives, environmental knowledge claims, multiple ontologies, climate change adaptation, and the spatial and temporal shaping of socio-ecological struggles for climate and marine justice in more detail. Furthermore, it takes up current strands of climate and marine justice scholarship and explores avenues for further research.

Full textAbstract:
Robust evidence exists that certain extreme weather and climate events, especially daily temperature and precipitation extremes, have changed in regard to intensity and frequency over recent decades. These changes have been linked to human-induced climate change, while the degree to which climate change impacts an individual extreme climate event (ECE) is more difficult to quantify. Rapid progress in event attribution has recently been made through improved understanding of observed and simulated climate variability, methods for event attribution and advances in numerical modelling. Attribution for extreme temperature events is stronger compared with other event types, notably those related to the hydrological cycle. Recent advances in the understanding of ECEs, both in observations and their representation in state-of-the-art climate models, open new opportunities for assessing their effect on human and natural systems. Improved spatial resolution in global climate models and advances in statistical and dynamical downscaling now provide climatic information at appropriate spatial and temporal scales. Together with the continued development of Earth System Models that simulate biogeochemical cycles and interactions with the biosphere at increasing complexity, these make it possible to develop a mechanistic understanding of how ECEs affect biological processes, ecosystem functioning and adaptation capabilities. Limitations in the observational network, both for physical climate system parameters and even more so for long-term ecological monitoring, have hampered progress in understanding bio-physical interactions across a range of scales. New opportunities for assessing how ECEs modulate ecosystem structure and functioning arise from better scientific understanding of ECEs coupled with technological advances in observing systems and instrumentation.

Abstract The two principal policy approaches to global climate change include mitigation and adaption. In recent years, the interest in adaptation and “resilience” has increased significantly in part because anthropogenic climate change appears unavoidable and mitigation agreements are difficult to achieve. This article takes a critical look at the emerging discourse over climate change adaptation and resilience. By drawing upon critiques of environmental resource management and adaptive comanagement, this paper argues that taking the concept of adaptation for granted as an appropriate bottom-up strategy for coping with anthropogenic climate change not only ignores the political and economic contexts in which this environmental strategy developed, but might also unintentionally subvert the vulnerable communities it intends to benefit. Using an ethnographic case study of the 2004 Boscastle Harbour flood in North Cornwall, England, this paper explores the paradoxical way in which adaptation and resilience work within the apparatus of the neoliberal state, which aims to shift responsibility for social and environmental problems to the individual. By better understanding the political and economic processes embedded in the concepts of adaptation and resilience, researchers will be more effective at finding equitable solutions to human ecological problems. Adaptation to the adverse effects of climate change is vital in order to reduce the impacts of climate change that are happening now and increase resilience to future impacts (United Nations Framework Convention on Climate Change).

This paper summarizes current knowledge about the optical properties of greenhouse gases and general climate-warming influences. It explains the influence of this new phenomenon on the major ecosystems of the world, and considers the process of deforestation. It then analyzes the warming trends in Ontario based on data from two weather stations with continuous records of more than 120 years, to determine the rate of warming in the Great Lakes-St. Lawrence Region. The results indicate a temperature increase of about 0.76 °C per century and an 8% increase in annual total precipitation.Current climate change models indicate that for a scenario of 2 × CO2 levels some general, probable prognoses can be made, including a temperature increase of up to 4.5 °C, which might be disastrous for existing forest ecosystems. Specifically, the consequences of climate warming on (a) northward shifts of ecological conditions, (b) forest productivity, and (c) forest physiology and health, are examined. In the context of global warming, the paper then recommends practical management measures necessary to ensure adaptation of existing forest ecosystems to the warming that is already developing. These measures are intended to provide a no-risk environment for existing forests until rotation age. Next, a wide range of mitigative measures is examined with a view to securing the long-term preservation of forest ecosystems to avoid major ecological disruptions and, gradually, to reverse climate warming. Application of these measures requires international consensus, but countries that apply these recommendations first have a chance to profit from them due to the "CO2 fertilization" effect. Key words: climate change, silviculture, forest management

Full textAbstract:
River flows in the Murray–Darling Basin, as in many regions in the world, are vulnerable to climate change, anticipated to exacerbate current, substantial losses of freshwater biodiversity. Additional declines in water quantity and quality will have an adverse impact on existing freshwater ecosystems. We critique current river-management programs, including the proposed 2011 Basin Plan for Australia’s Murray–Darling Basin, focusing primarily on implementing environmental flows. River management programs generally ignore other important conservation and adaptation measures, such as strategically located freshwater-protected areas. Whereas most river-basin restoration techniques help build resilience of freshwater ecosystems to climate change impacts, different measures to enhance resilience and reoperate water infrastructure are also required, depending on the degree of disturbance of particular rivers on a spectrum from free-flowing to highly regulated. A crucial step is the conservation of free-flowing river ecosystems where maintenance of ecological processes enhances their capacity to resist climate change impacts, and where adaptation may be maximised. Systematic alteration of the operation of existing water infrastructure may also counter major climate impacts on regulated rivers.

Full textAbstract:
Coastal social-ecological systems are vulnerable to climate change with impacts distributed unequally amongst human communities. Vulnerability assessments, an increasingly popular methodology for understanding variability in vulnerability and its components, often fail to include or recognize the perceptions of individuals in the focal system. Perceptions of climate vulnerability are influenced by experiences, social networks, and cognitive biases, and often differ from vulnerability as measured by subject experts. Because perceptions influence human behavior, including if and how people take adaptive action, a failure to recognize perceptions can lead to ineffective adaptation plans and an incomplete understanding of system vulnerability. Here, as part of a novel, multi-method effort to evaluate vulnerability to climate change in the California Current social-ecological system, we survey fishers from Washington, Oregon, and California to understand their perceived vulnerability and investigate what factors drive variability in their views. We find that while there is a connection between some factors known to influence vulnerability of fishers, including vessel size and the diversity of fishing portfolios, the most significant predictor of higher perceived vulnerability was environmental worldview, specifically a belief that climate change is occurring. Motivation to adapt is also influenced by the sentiment that the impacts of climate change are more urgent and consequential than other problems; thus, we also evaluate how concern levels for environmental issues compare to other challenges that may affect fishing success and wellbeing. While just under half think that they will be personally harmed by climate change, generally the fishers were more concerned about issues like costs and regulations than they were about environmental impacts. This assessment of perceptions highlights the importance of communication and addressing cognitive barriers to adaptation in the effort to develop climate resilient fisheries and fishing communities in the United States.

Abstract For decades, many Australian coastal communities have been changing, in varying degrees, from traditional “fishing towns” to “mining”, “tourism”, or “retirement” towns. However, environmental changes, such as climate change, have increased the vulnerability of these communities and their capacity to continue to successfully adapt is unknown. A framework for the assessment of socio-ecological vulnerability is used to provide information on the response to change in Geraldton, Western Australia. Geraldton has traditionally been a port and fishing town and has recently become a hub for the expanding mining industry. An innovative historical assessment of adaptive capacity using sustainable livelihoods analysis with indicators of social, economic, human, financial, physical, and natural capital is used to calculate socio-ecological vulnerability over time. The framework integrates adaptive capacity with environmental change, resource dependence, and the socio-economic importance of the fished species during four census years: 1921, 1954, 1981, and 2011. The earlier years are characterized by high adaptive capacity and low socio-ecological vulnerability in keeping with strong economic growth and low unemployment rates following the First and Second World Wars. The years 1981 and 2011 showed markedly higher socio-ecological vulnerability and lower adaptive capacities. This result was due to progressively greater exposure to climate change and the high socio-economic importance of fished species, as well as relatively poor physical, social, and natural capital. With continuing environmental and economic change, the fishing industry and the broader Geraldton population is likely to become increasingly vulnerable. Proactive rather than passive adaptation may speed the recovery and reduce a decline in the fishing industry and local economies. The paper briefly discusses potential adaptation in Geraldton which may be useful as a guideline for other coastal communities.

The global climate system is changing faster than earlier projections with variable rates across the geographic scale. The impacts are also perceived heterogeneously across the places and communities. This study explores gender differentials in impact-perception in the Kaligandaki river valley in central Nepal. Research used primary data collected from 360 households, 75 Key Informants and 24 Focus Groups Discussion as well as through construction of nine Historical Timeline Calendars from three clusters – Meghauli (lower basin), Lumle (middlepart) and Upper-Mustang (upper-basin). The impact perception was assessed under seven social-ecological variables in the unipolar Likert Scale. The impact perception does not significantly differ across the gender of respondents while testing the means of perception scores and probably it is due to the impacts that have been experienced at profound level. The test of independence of gender to level of impacts indicates no significant association. This research also tried to check if other social-economic variables such as age of respondents and landholding size of household as well as self-reported economic status of households were significantly associated with some of the impacts. However, the number of cells with expected counts less than 5 in chi-square test turned to be more than 20 percent so they were considered to be invalid. Nevertheless, impact perception is significantly associated with the places of residence or study clusters, which indicates that local social-ecological system matters in climate change impacts. The qualitative information however, suggests otherwise that women feel higher level of risk and impacts, and is related to their concern over the welfare of family members and livelihood resources. Since risk perception is found to be related to spatial characteristics, this research recommends for development and implementation of targeted and localized adaptation policies. None the less, those policies must also recognize the women’s concerns on climate change impacts.

The Antarctic biota has evolved over the last 100 million years in increasingly isolated and cold conditions. As a result, Antarctic species, from micro-organisms to vertebrates, have adapted to life at extremely low temperatures, including changes in the genome, physiology and ecological traits such as life history. Coupled with cycles of glaciation that have promoted speciation in the Antarctic, this has led to a unique biota in terms of biogeography, patterns of species distribution and endemism. Specialization in the Antarctic biota has led to trade-offs in many ecologically important functions and Antarctic species may have a limited capacity to adapt to present climate change. These include the direct effects of changes in environmental parameters and indirect effects of increased competition and predation resulting from altered life histories of Antarctic species and the impacts of invasive species. Ultimately, climate change may alter the responses of Antarctic ecosystems to harvesting from humans. The unique adaptations of Antarctic species mean that they provide unique models of molecular evolution in natural populations. The simplicity of Antarctic communities, especially from terrestrial systems, makes them ideal to investigate the ecological implications of climate change, which are difficult to identify in more complex systems.

Abstract We investigate the perceptions and impacts of climate change on 11 Indigenous communities in Northern British Columbia and Southeast Alaska. This coastal region constitutes an extremely dynamic and resilient social-ecological system where Indigenous Peoples have been adjusting to changing climate and biodiversity for millennia. The region is a bellwether for biodiversity changes in coastal, forest, and montane environments that link the arctic to more southerly latitudes on the Pacific coast. Ninety-six Elders and resource users were interviewed to record Traditional Ecological Knowledge (TEK) and observations regarding weather, landscape, and resource changes, especially as concerns what we term Cultural Keystone Indicator Species (CKIS), which provide a unique lens into the effects of environmental change. Our findings show that Indigenous residents of these communities are aware of significant environmental changes over their lifetimes, and an acceleration in changes over the last 15–20 years, not only in weather patterns, but also in the behaviour, distributions, and availability of important plants and animals. Within a broader ecological and social context of dwelling, we suggest ways this knowledge can assist communities in responding to future environmental changes using a range of place-based adaptation modes.

Abstract The study examines the seasonality in climate and extreme weather events, and its effect on cattle production in the Guinea Savannah ecological zone of Nigeria. The study uses both quantitative and qualitative approaches. Climate data of 34 years were used to examine the trends in rainfall pattern and climate variability while household survey was used to appraise the herders’ awareness of climate variability/change impacts and adaptation strategies. Cumulative Departure Index (CDI) method was used to assess the extreme weather events while descriptive statistics and multinomial logistic (MNL) regression model were used to identify the factors that determined herders’ adaptation strategies to climate change. The results revealed a significant spatiotemporal variation in both rainfall and temperature with CDI ranging from -1.39 to 3.3 and -2.3 to 1.81 respectively. The results revealed a reduction in the amount of water available for cattle production. From survey results, 97.5% of the herders identified drought as the major extreme weather event affecting livestock productivities in the study region. In the herder’s perception, the droughts are more severe in recent years than 34 years ago. The results from MNL revealed that extreme weather events, such as drought, has a positive likelihood on migration, at a 10% level of significance, the events has led to migration of cattle herders from the northern part of the study area toward the southern part in recent years.

Climate change has caused substantial losses, especially to smallholder farmers whose main source of livelihood is derived from agriculture. Climate change impacts can be reduced by enhancing coping and adaptation strategies. This study explores the coping and adaptation strategies of smallholder farming communities in the Limpopo Province, South Africa. As part of the assessment and analysis of drought, multiple sources of data were consulted, including 200 households’ socio-economic information, focus group discussions, and interviews. Extreme drought events are increasing, impacting negatively on smallholder farmers’ livelihoods. Adaptations to changing weather patterns were observed in smallholder farmers through planting early-maturing plants and drought-tolerant crops, altering planting dates, crop diversification, and irrigating in addition to non-farming activities. There is a need to enhance these context-based adaptation strategies to reduce risks and vulnerability and increase household resilience. Several socioeconomic developments and significant ecological deterioration appear to limit opportunities for long-term adaptation to drought.

Full textAbstract:
Land use plays a crucial role in climate change adaptation and mitigation, as the reasonable design of land use distribution can positively impact these things. Therefore, research interest in climate change adaptation and mitigation strategies in land use and management has been growing. However, the adaptation and mitigation strategies have been handled separately at different dimensions and spatial levels. In this study, we presented a modeling framework for land use optimization that integrates climate change adaptation and mitigation, developed the model, and then applied it to Huailai County, wherein environmental and socioeconomic conditions are sensitive to climate change. The regional land use optimization model was combined with a linear programming model and a modified cellular automata model. Subsequently, the climate change adaptation and mitigation constraints, including ecological water demand, spatial suitability, and carbon sequestration, were incorporated into the model. The results indicate that most regions in the study area could adapt to and mitigate climate change with a constant land use pattern, and the land use conversion region under different climate change scenarios was primarily located in the topography transition region. The optimization results also reveal trade-offs between climate change adaptation and mitigation that were manifested with an increase in carbon sequestration and ecological water demand accompanied by decreases in the net income of agricultural production. Thus, it is necessary to simultaneously incorporate climate change adaptation and mitigation into land use optimization and management, and the proposed model provides a feasible method to incorporate them and balance their trade-offs in land use pattern optimization at a regional scale.

Climate change has started impacting species, ecosystems, genetic diversity within species, and ecological interactions and is thus a serious threat to conserving biodiversity globally. In the absence of adequate adaptation measures, biodiversity may continue to decline, and many species will possibly become extinct. Given that global temperature continues to increase, climate change adaptation has emerged as an overarching framework for conservation planning. We identified both ongoing and probable climate change adaptation actions for greater one-horned rhinoceros conservation in Nepal through a combination of literature review, key informant surveys (n = 53), focus group discussions (n = 37) and expert consultation (n = 9), and prioritised the identified adaptation actions through stakeholder consultation (n = 17). The majority of key informants (>80%) reported that climate change has been impacting rhinoceros, and more than 65% of them believe that rhinoceros habitat suitability in Nepal has been shifting westwards. Despite these perceived risks, climate change impacts have not been incorporated well into formal conservation planning for rhinoceros. Out of 20 identified adaptation actions under nine adaptation strategies, identifying and protecting climate refugia, restoring the existing habitats through wetland and grassland management, creating artificial highlands in floodplains to provide rhinoceros with refuge during severe floods, and translocating them to other suitable habitats received higher priority. These adaptation actions may contribute to reducing the vulnerability of rhinoceros to the likely impacts of climate change. This study is the first of its kind in Nepal and is expected to provide a guideline to align ongoing conservation measures into climate change adaptation planning for rhinoceros. Further, we emphasise the need to integrating likely climate change impacts while planning for rhinoceros conservation and initiating experimental research and monitoring programs to better inform adaptation planning in the future.

AbstractThe enhanced or reduced growth of juvenile masu salmon (Oncorhynchus masou masou) may result from climate changes to their environment and thus impact on the eco-evolutionary dynamics of their life-history choices. Male juveniles with status, i.e., if their body size is larger than a threshold, stay in the stream and become resident males reproducing for multiple years, while those with smaller status, i.e., their body size is below the threshold, migrate to the ocean and return to the stream one year later to reproduce only once. Since juvenile growth is suppressed by the density of resident males, the fraction of resident males may stay in equilibrium or fluctuate wildly over a 2-year period. When the threshold value evolves, the convergence stable strategy may generate either an equilibrium or large fluctuations of male residents. If environmental changes occur faster than the rate of evolutionary adaptation, the eco-evolutionary dynamics exhibit a qualitative shift in the population dynamics. We also investigated the relative assessment models, in which individual life-history choices are made based on the individual’s relative status within the juvenile population. The eco-evolutionary dynamics are very different from the absolute assessment model, demonstrating the importance of understanding the mechanisms of life history choices when predicting the impacts of climate change.

Adaptation and mitigation to the adverse impacts of rising weather and climate extremes require businesses to respond with adequate marketing strategies promoting sustained economic development. Unfortunately, the connections exploring such relationships have not been extensively investigated in the current body of literature. This study investigated the five marketing categories relating to sustainable practices (sustainable marketing, social marketing, green marketing, sustainable consumption and ecological marketing) within core research themes of climate change, global warming and sustainability from a bibliometric approach using the Scopus API. Additional topic modelling was conducted using the Latent Dirichlet Allocation (LDA) unsupervised approach on downloaded abstracts to distinguish ideas communicated in time through research and publications with co-occurrences of major Intergovernmental Panel on Climate Change (IPCC) Assessment Reports and Google search queries. The results confirmed marketing strategies aligned with the theme of sustainability with little work from small developing island nations. Additionally, findings demonstrated that research exploring business strategies through green marketing directed to green consumers with sustainable supply chain management had been dominantly increasing in the literature over recent years. Similarly, social marketing associated with green consumers was a common concern for the public and academics, rising over the years with strong influence from the published IPCC Assessment Reports. This study did not explore other published databases, including climate change-related meeting transcripts and published speeches from corporate and world leaders.

Protected areas are the most common and most important strategy for biodiversity conservation and are called for under the United Nations' Convention on Biological Diversity. However, most protected areas have been designed to represent (and in theory protect for perpetuity) specific natural features, species and ecological communities in-situ, and have not taken into account potential shifts in ecosystem distribution and composition that could be induced by global climatic change. This paper provides an overview of the policy and planning implications of climate change for protected areas in Canada, summarizes a portfolio of climate change adaptation options that have been discussed in the conservation literature and by conservation professionals and provides a perspective on what is needed for the conservation community in Canada to move forward on responding to the threat posed by climate change. Key words: climate change, protected areas, parks, conservation, system planning, impacts, adaptation

Abstract Starting from the fact that the principles of agro-ecology become fundamental principles for the development of a green economy, especially in the context of current climate change, the effective capitalization of the ecological conditions of an agricultural area is one of the main objectives of agricultural science and practice. Identifying and formulating adaptive technological solutions can guide any producer to capitalize different climate and soil conditions. The sandy soils in Southern Oltenia offer less favourable ecological conditions, and the cultivation of watermelons is now profitable enough for such conditions. Growers are, however, interested in getting the most productive yields, early and profitable, even under the conditions of climate change. The current paper quantifies the grafting of watermelons in the conditions of the sandy soils of Dăbuleni, with poor soil supply, with meteorological drought phenomena and agricultural drought risk, in terms of quality and quantity of production under the climatic conditions in 2015-2017. The results, correlated with the climatic conditions, recommend the cultivation of grafted watermelons, offering the producers in the area a niche of ecological adaptation, ensuring the resistance of plants to abiotic, thermo-hydric stress factors, and improving the resistance to low temperatures, heat and drought.

Abstract Climate change is a serious threat to local communities in West Africa. This study evaluated climatic trends and the perceptions of farmers to climate change in central Côte d’Ivoire. We surveyed 259 households across three agro-ecological zones. The knowledge of farmers about climate change was compared to observed trends of various climatic parameters from meteorological records (1973-2016). Results from trend analysis and descriptive analysis showed that the minimum, maximum and mean temperatures and rainfall showed a significant upward trend in all ecoregions. The average temperature and amount of rainfall increased by 3.2% (0.89°C) and 166.58% (645.5 mm) respectively over the 44 years. Local farmers perceived an increasing trend in temperature (all respondents) and a decreasing trend in rainfall (91.51%). Most of the respondents identified deforestation (76.83%), natural climate variation (50.97%) and wildfires (31.27%) as the main causes of these climatic disturbances, which induced plant dieback (92.66%), poor crop growth (59.46%) and crop loss (20.46%). The impacts on people and their assets encompassed a decrease in household income (63.71%), demolition of roofs (44..4%) and walls (43.91%) of houses, the scarcity of water points (39.38%) and the emergence of new diseases (30.89%). These climatic disturbances resulted in specific endogenous on-farm and off-farm strategies to adapt to the impacts of observed changes on their livelihoods.

Climate change has been considered, at a global level, as one of the main anthropogenic drivers of environmental transformation, especially on biomes, ecosystems and the most vulnerable population. In this regard, the concept of resilience has been widely used in ecology to explain the ecosystem transition thresholds by which forests and other habitats are able to restructure in the face of various external disturbances. However, the concept of resilience in facing climate change impacts and risks through the lens of socio-environmental risks in Brazil is still underdeveloped, especially at the biome level. This article uses the theory of critical transitions to ecological niche distribution modeling in future global warming scenarios by the end of the century, in order to highlight the change in ecological resilience of the Amazon, Caatinga, Cerrado, Atlantic Forest and Pampa biomes, and how the changes in resilience can lead to an increased exposure, vulnerabilities and risks to socio-environmental security. This article shows how an interdisciplinary approach bringing together modeling of biome resilience may be a tool to support decision making and public policies on mitigation and adaptation to climate change and reduce risks to socio-environmental security.
