IPCC's current conceptualization of 'vulnerability' needs more clarification for climate change vulnerability assessments.

In this Short Communication, we raise the concern that the existing conceptualization of 'vulnerability', introduced in the IPCC Fifth Assessment Report (AR5), is not facilitative for standalone vulnerability assessments and that this conceptualization has not been well accepted by the vulnerability researchers. We identify three key reasons for low adoption of the AR5 conceptualization in climate change vulnerability assessments, and urge the IPCC Working Group II to clarify how the current conceptualization of 'vulnerability' can facilitate standalone climate change vulnerability assessments. We propose treating 'exposure' not only as a precondition for vulnerability but also as a secondary driver of vulnerability to capture the influence of differential exposure.

Operationalizing the feedback between institutional decision-making, socio-political infrastructure, and environmental risk in urban vulnerability analysis.

Urban adaptation to climate change is likely to emerge from the responses of residents, authorities, and infrastructure providers to the impact of flooding, water scarcity, and other climate-related hazards. These responses are, in part, modulated by political relationships under cultural norms that dominate the institutional and collective decisions of public and private actors. The legacy of these decisions, which are often associated with investment in hard and soft infrastructure, has lasting consequences that influence current and future vulnerabilities. Making those decisions visible, and tractable is, therefore, an urgent research and political challenge in vulnerability assessments. In this work, we present a modeling framework to explore scenarios of institutional decision-making and socio-political processes and the resultant effects on spatial patterns of vulnerability. The approach entails using multi-criteria decision analysis, agent-based models, and geographic information simulation. The approach allows for the exploration of uncertainties, spatial patterns, thresholds, and the sensitivities of vulnerability outcomes to different policy scenarios. Here, we present the operationalization of the framework through an intentionally simplified model example of the governance of water in Mexico City. We discuss results from this example as part of a larger effort to empirically implement the framework to explore sociohydrological risk patterns and trade-offs of vulnerability in real urban landscapes.

Managing household socio-hydrological risk in Mexico city: A game to communicate and validate computational modeling with stakeholders.

Residents of Mexico City experience major hydrological risks, including flooding events and insufficient potable water access for many households. A participatory modeling project, MEGADAPT, examines hydrological risk as co-constructed by both biophysical and social factors and aims to explore alternative scenarios of governance. Within the model, neighborhoods are represented as agents that take actions to reduce their sensitivity to exposure and risk. These risk management actions (to protect their households against flooding and scarcity) are based upon insights derived from focus group discussions within various neighborhoods. We developed a role-playing game based on the model's rules in order to validate the assumptions we made about residents' decision-making given that we had translated qualitative information from focus group sessions into a quantitative model algorithm. This enables us to qualitatively validate the perspective and experience of residents in an agent-based model mid-way through the modeling process. Within the context of described hydrological events and the causes of these events, residents took on the role of themselves in the game and were asked to make decisions about how to protect their households against scarcity and flooding. After the game, we facilitated a discussion with residents about whether or not the game was realistic and how it could be improved. The game helped to validate our assumptions, validate the model with community members, and reinforced our connection with the community. We then discuss the potential further development of the game as a learning and communication tool.

Does external funding help adaptation? Evidence from community-based water management in the Colombian Andes.

Despite debate regarding whether, and in what form, communities need external support for adaptation to environmental change, few studies have examined how external funding impacts adaptation decisions in rural resource-dependent communities. In this article, we use quantitative and qualitative methods to assess how different funding sources influence the initiative to adapt to water scarcity in the Colombian Andes. We compare efforts to adapt to water scarcity in 111 rural Andean communities with varied dependence on external funding for water management activities. Findings suggest that despite efforts to use their own internal resources, communities often need external support to finance adaptation strategies. However, not all external financial support positively impacts a community's abilities to adapt. Results show the importance of community-driven requests for external support. In cases where external support was unsolicited, the results show a decline, or "crowding-out," in community efforts to adapt. In contrast, in cases where communities initiated the request for external support to fund their own projects, findings show that external intervention is more likely to enhance or "crowds-in" community-driven adaptation.

Integration of urban science and urban climate adaptation research: opportunities to advance climate action.

There is a growing recognition that responding to climate change necessitates urban adaptation. We sketch a transdisciplinary research effort, arguing that actionable research on urban adaptation needs to recognize the nature of cities as social networks embedded in physical space. Given the pace, scale and socioeconomic outcomes of urbanization in the Global South, the specificities and history of its cities must be central to the study of how well-known agglomeration effects can facilitate adaptation. The proposed effort calls for the co-creation of knowledge involving scientists and stakeholders, especially those historically excluded from the design and implementation of urban development policies.

Sense of Agency, Affectivity and Social-Ecological Degradation: An Enactive and Phenomenological Approach.

In the last few years, there has been an interest in understanding the impact of environmental change and degradation on people's affective life. This issue has become particularly pressing for populations whose form of life is heavily dependent on ecosystem services and functions and whose opportunities for adaptation are limited. Based on our work with farmers from the Xochimilco urban wetland in the southwest of Mexico City, we begin to draw a theoretical approach to address and explain how environmental degradation impacts people's affective life and sense of agency. Farmers who were part of our project referred to a sense of despair and helplessness toward the loss of the ecosystem and their traditional farming-based form of life. From the perspective of phenomenology, enactivism and ecological psychology, we argue that the loss of this form of life in the area is related to the degradation of socio-ecological systems, limiting the opportunities for people to relate meaningfully to others and the environment. We posit that losing meaningful interaction with the environment generates a feeling of loss of control while leading farmers to feel frustrated, anxious and stressed. Such affective conditions have a direct impact on their sense of agency. In terms of adaptation, the negative interaction between degradation, affective states and a diminished sense of agency can create a downward spiral of vulnerability, including political vulnerability.

Public sector reform and governance for adaptation: implications of new public management for adaptive capacity in Mexico and Norway.

Although many governments are assuming the responsibility of initiating adaptation policy in relation to climate change, the compatibility of "governance-for-adaptation" with the current paradigms of public administration has generally been overlooked. Over the last several decades, countries around the globe have embraced variants of the philosophy of administration broadly called "New Public Management" (NPM) in an effort to improve administrative efficiencies and the provision of public services. Using evidence from a case study of reforms in the building sector in Norway, and a case study of water and flood risk management in central Mexico, we analyze the implications of the adoption of the tenets of NPM for adaptive capacity. Our cases illustrate that some of the key attributes associated with governance for adaptation--namely, technical and financial capacities; institutional memory, learning and knowledge; and participation and accountability--have been eroded by NPM reforms. Despite improvements in specific operational tasks of the public sector in each case, we show that the success of NPM reforms presumes the existence of core elements of governance that have often been found lacking, including solid institutional frameworks and accountability. Our analysis illustrates the importance of considering both longer-term adaptive capacities and short-term efficiency goals in public sector administration reform.

Adaptive capacity and social-environmental change: theoretical and operational modeling of smallholder coffee systems response in Mesoamerican Pacific Rim.

Communities who rely directly on the natural environment for their survival typically have developed risk management strategies to enable them to avoid dangerous thresholds of change to their livelihoods. Development policy appropriate for natural resource-based communities requires an understanding of the primary drivers of social-ecological change, the ways in which affected households autonomously respond to such drivers, and the appropriate avenues for intervention to reduce vulnerability. Coffee has been, and still remains, one of the most important commodities of the Mesoamerican region, and hundreds of thousands of smallholder households in the region are dependent in some way on the coffee industry for their livelihood stability. We used the Analytical Network Process to synthesize expert knowledge on the primary drivers of livelihood change in the region as well as the most common household strategies and associated capacities necessary for effective response. The assessment identified both gradual systemic processes as well as specific environmental and market shocks as significant drivers of livelihood change across the region. Agronomic adjustments and new forms of social organization were among the more significant responses of farmers to these changes. The assessment indicates that public interventions in support of adaptation should focus on enhancing farmers' access to market and technical information and finance, as well as on increasing the viability of farmers' organizations and cooperatives.

An obsolete dichotomy? Rethinking the rural­urban interface in terms of food security and production in the global south.

The global food system is coming under increasing strain in the face of urban population growth. The recent spike in global food prices (2007­08) provoked consumer protests, and raised questions about food sovereignty and how and where food will be produced. Concurrently, for the first time in history the majority of the global population is urban, with the bulk of urban growth occurring in smaller-tiered cities and urban peripheries, or 'peri-urban' areas of the developing world. This paper discusses the new emerging spaces that incorporate a mosaic of urban and rural worlds, and reviews the implications of these spaces for livelihoods and food security. We propose a modified livelihoods framework to evaluate the contexts in which food production persists within broader processes of landscape and livelihood transformation in peri-urban locations. Where and how food production persists are central questions for the future of food security in an urbanising world. Our proposed framework provides directions for future research and highlights the role of policy and planning in reconciling food production with urban growth.

Crisis, transformation, and agency: Why are people going back-to-the-land in Greece?

Transformations are fundamentally about agency: human intention, motivation, and power to influence and to resist. Most studies focus on deliberate system-level transformations, usually guided by a set of influential actors. However, system-level transformations may also occur as the result of the cascading effects of multiple individual transformations in response or in anticipation to various crises. Little is known about how crises foster these individual transformations, and how these may relate to different types of system-level change. This article fills this gap by looking at how crisis fosters two different types of agencies-internal and external-and how these link to individual transformations in the case of Greece's back-to-the-land movement whereby urbanites sought to reconnect with land-based livelihoods during the economic crisis (2008 onwards). The article draws on the qualitative analysis of 76 interviews of back-to-the-landers to further understand why people are going back-to-the-land (their motivations), how these relate to the concept of agency and individual transformation, and what implications might there be for system-level social-ecological transformations. This article makes three key points. First, crises create different opportunity contexts that may lead to rapid changes in what is valued in the broader social discourse. While social values and discourses are usually considered to be "deep levers" and slow to change, we found that they can rapidly shift in times of crises, challenging notions of the role of fast vs. slow variables in system transformations. Second, agency is needed to respond to crises but is also further catalyzed and enhanced through crisis; activating one's internal agency leads to personal transformations as well as collective transformations (linked to external agency), which are mutually co-constitutive. And third, systemic-level transformation emerges through multiple pathways including through the aggregation of multiple individual transformations that may lead to emergent system-level changes.

Nested and teleconnected vulnerabilities to environmental change.

The vulnerability of distant peoples and places to global change in environment and society is nested and teleconnected. Here, we argue that such vulnerabilities are linked through environmental change process feedbacks, economic market linkages, and flows of resources, people, and information. We illustrate these linkages through the examples of the global transmission of severe acute respiratory syndrome (SARS) and the interdependent vulnerabilities and adaptations of coffee farmers in Vietnam and Mexico. These cases demonstrate that the vulnerability of specific individuals and communities is not geographically bounded but, rather, is connected at different scales, so that the drivers of their exposure and sensitivity are inseparable from large-scale processes of sociocultural change and market integration. Aggregate outcomes of government policies, trends in global commodity markets, and even decisions by individuals to improve livelihood security can have negative repercussions, not only locally, through transformations of ecological systems and social relations, but also at larger scales.

Chiapas' Delayed Entry into the International Labour Market: A Story of Peasant Isolation, Exploitation, and Coercion.

This manuscript presents a synthetic view of Chiapas' migration history over the last century through a thorough examination of relevant English and Spanish-language literature sources. Unlike most Mexican states, Chiapas did not heavily rely upon migration, especially international migration, as an economic strategy until very recently. The reasons that underlie Chiapas' late adoption of economic migration include socio-political and economic structural factors that shaped rural and agrarian policy and demographic trends. This paper evaluates these structural factors with regards to several migration theories to assist our understanding of how and why Chiapans were prevented or discouraged from leaving their native communities. The paper concludes by detailing the perfect cascade of climatic, demographic, economic and political factors that ultimately forced Chiapans to resort to international migration as a major economic diversification strategy.
