Recent advances on power, politics, and pathways in climate change adaptation aim to re-frame decision-making processes from development-as-usual to openings for transformational adaptation. This paper offers empirical insights regarding decision-making politics in the context of collective learning through participatory scenario building and flexible flood management and planning in the Eastern Brahmaputra Basin of Assam, India. By foregrounding intergroup and intragroup power dynamics in such collective learning spaces and how they intersect with existing micropolitics of adaptation on the ground, we examine opportunities for and limitations to challenging entrenched authority and subjectivities. Our results suggest that emancipatory agency can indeed emerge but is likely to be fluid and multifaceted. Community actors who are best positioned to resist higher-level domination may well be imbricated in oppression at home. While participatory co-learning as embraced here might open some spaces for transformation, others close down or remain shut. 相似文献
Climate adaptation for coastal infrastructure projects raises unique challenges because global-scale environmental changes may require similar projects to be completed in many locations over the same time frame. Existing methods to forecast resource demand and capacity do not consider this phenomenon of a global change affecting many localities and the resulting increased demand for resources. Current methods do not relate to the most up-to-date climate science information, and they are too costly or too imprecise to generate global, regional, and local forecasts of “climate-critical resources” that will be required for infrastructure protection. They either require too much effort to create the many localized designs or are too coarse to consider information sources about local conditions and structure-specific engineering knowledge. We formalized the concept of a “minimum assumption credible design” (MACD) to leverage available local information (topography/bathymetry and existing infrastructure) and the essential engineering knowledge and required construction materials (i.e., a design cross-section template). The aggregation of the resources required for individual local structures then forecasts the resource demand for global adaptation projects. We illustrate the application of the MACD method to estimate the demand for construction materials critical to protect seaports from sea-level-rise-enhanced storm surges. We examined 221 of the world’s 3,300+ seaports to calculate the resource requirements for a coastal storm surge protection structure suited to current upper-bound projections of two meters of sea level rise by 2100. We found that a project of this scale would require approximately 436 million cubic meters of construction materials, including cement, sand, aggregate, steel rebar, and riprap. For cement alone, ∼49 million metric tons would be required. The deployment of the MACD method would make resource forecasts for adaptation projects more transparent and widely accessible and would highlight areas where current engineering knowledge or material, engineering workforce, and equipment capacity fall short of meeting the demands of adaptation projects. 相似文献
The stakes for alleviating poverty and avoiding unbridled climate change are inextricably linked. Climate change impacts will slow down and may even reverse trends in poverty reduction. The pathways consistent with global warming of no more than 2?°C require strategies for poverty alleviation to make allowance for the constraint of low-carbon development. Existing climate funds have failed to target poverty alleviation as a high-priority strategy for adaptation or as a component of low-carbon development. This article proposes a funding window as part of the Green Climate Fund in order to foster synergies targeting greater satisfaction of basic needs, while making allowance for adaptation and mitigation. This financial mechanism is based on indicators of the satisfaction of basic needs and could respond to the claims of the developing countries, which see alleviating poverty as the first priority in climate negotiations. It defines a country continuum, given that there are poor people everywhere; all developing countries are therefore eligible with a mechanism of this sort.Policy relevanceThe Intergovernmental Panel on Climate Change (IPCC) calls for substantial emissions reductions and adaptation strategies over the next decades to reduce the high risks of severe impacts of climate change over the 21st century. Industrialized countries and developing countries alike recognize the need to mitigate climate change and to adapt to it. But they face many challenges that lead to an ‘emissions gap’ between an emissions level consistent with the 2?°C increase limit and the voluntary pledges that they have made thus far in the climate negotiations (United Nations Environment Programme. (2014). The Emissions Gap Report 2014. A UNEP synthesis report). In this arena, many developing countries underline that their first domestic priority is the satisfaction of basic needs. In the run-up to the next climate negotiations at the 21st Conference of the Parties (COP 21) in Paris, the proposed poverty-adaptation-mitigation funding window could contribute to alleviate the conflict between development and climate goals in developing countries. In this sense, it could spur developing countries to integrate more ambitious emissions limitations pledges into their Intended Nationally Determined Contributions. This could in turn entice industrialized countries to act similarly. In the end, it could pave the way to an ambitious climate agreement in Paris at COP 21. 相似文献
There has been a growing recognition regarding the use of social networks to engage communities in government actions. However, despite increasing awareness of social networks, there is very limited evidence for their application in relation to climate policy. This study fills this gap by assessing the potential of social networks for engaging local communities in climate adaptation policy, drawing on a case study of the Shoalhaven region in Australia. Participants from key representative groups were recruited using a purposive snowball sampling technique (N?=?24). By mapping knowledge acquisition and diffusion networks in relation to climate adaption at the local scale, this study identified key nodes within the networks. Findings demonstrate that although climate adaptation information was acquired from a diverse range of sources, the sharing knowledge networks were far more dispersed. Furthermore, although 165 knowledge sources were identified, three nodes had coverage cross the entire network, and as such acted as boundary spanners within the sharing network. This research demonstrates the utility of social network analysis to reveal the underlying knowledge networks and structures that influence community engagement pathways and in doing so outlines key implications in relation to engaging local communities in climate policy and action.Policy relevanceThe rapid development of adaptation as a mainstream strategy for managing the risks of climate change has resulted in the emergence of a broad range of adaptation policies and management strategies globally. However, the success of these initiatives is largely dependent on their acceptance and uptake by local communities, which to date remains a significant challenge. Accordingly, policy makers require novel approaches to overcome barriers to community engagement so as to enhance the likely success of community engagement pathways. This article demonstrates the value of using social network analysis to reveal the underlying knowledge network structures. This approach makes it possible to identify key individuals within a community who can disseminate adaptation information quickly across broad geographic ranges. By utilizing this approach, policy makers globally will be able to increase the extent to which adaption initiatives are accepted and adhered to by local communities, thus increasing their success. 相似文献
The agri-food sector has contributed significantly to climate change, but has an important role to play in climate change mitigation and adaptation. The agri-food sector has many potential win–win–win strategies that benefit mitigation and adaptation, and also deliver gains in rural income and land management. Post-Soviet transition economies provide a good model for understanding some of the barriers to adaptation and mitigation in the agri-food sector, due to their significant unmet agricultural potential combined with inefficient energy use. Ukraine is used as a case study to explore the barriers and bridges to addressing climate change in a post-Soviet state. A variety of stakeholders and farmers were interviewed about mitigation and adaptation and the current response capacity. Grounded theory analysis revealed themes that are perceived to function as barriers including: pandering, oligarchs and market interventions; corruption and transparency; and survival, freedom and law enforcement. Foreign involvement and investment emerged as a bridge to overcoming these barriers. The results indicate that significant progress in climate mitigation and adaptation in the agri-food sector in Ukraine will only be achieved if some of the wider political and social issues facing the country can be addressed.

Ukraine has considerable potential for both agricultural production and climate change mitigation; however, this potential can only be met by identifying and addressing barriers currently impeding progress. This article found that barriers to effective climate change are perceived to stem from wider post-Soviet transition issues. These wider issues need to be addressed during the implementation of climate policy since they are viewed to be important by a wide variety of stakeholders. International negotiations have provided little incentive for Ukraine to achieve effective mitigation, and corrupt practices further impair mitigation projects. In addition, export quotas currently function as a maladaptive climate policy and reduce both farmers' capacity in Ukraine and international food security. Meanwhile, foreign involvement, not just financial investment, but also the investment of ideas can provide a bridge to effective climate policy. The international community needs to provide a legal framework and assist Ukraine in adopting transparent processes in order to successfully execute climate policy. 相似文献
India has 64 Mha under forests, of which 72% are tropical moist deciduous, dry deciduous, and wet evergreen forest. Projected changes in temperature, rainfall, and soil moisture are considered at regional level for India under two scenarios, the first involving greenhouse gas forcing, and the second, sulphate aerosols. Under the former model, a general increase in temperature and rainfall in all regions is indicated. This could potentially result in increased productivity, and shift forest type boundaries along attitudinal and rainfall gradients, with species migrating from lower to higher elevations and the drier forest types being transformed to moister types. The aerosol model, however, indicates a more modest increase in temperature and a decrease in precipitation in central and northern India, which would considerably stress the forests in these regions.Although India seems to have stabilized the area under forest since 1980, anthropogenic stresses such as livestock pressure, biomass demand for fuelwood and timber, and the fragmented nature of forests will all affect forest response to changing climate. Thus, forest area is unlikely to expand even if climatically suitable, and will probably decrease in parts of northeast India due to extensive shifting cultivation and deforestation. A number of general adaptation measures to climate change are listed. 相似文献
