Small-scale fisheries in developing regions are particularly vulnerable to climate change, but the assessment of climate-induced changes and impacts are often hampered by the data poor-situation of these social-ecological systems. Based on 40 years of scientific and local ecological knowledge, we provide a coherent narrative about the effects of a marine hotspot of climate change on a small-scale fishery across different geographical and temporal scales. We applied a mixed-methods approach to assess biophysical changes, social-ecological impacts, and the incremental spectrum of actions implemented at multiple levels to increase the adaptive capacity of a small-scale clam fishery. The warming hotspot here analyzed was the fastest-warming region in the South Atlantic Ocean. Long-term changes in wind intensity and direction were also noticeable at a regional scale. Both sea surface temperature and winds showed a clear shifting pattern in the late 1990 s. These climate-related stressors determined ecosystem and targeted population changes (e.g. clam mass mortalities, slow stock recovery rates after ecological shocks, habitat narrowing), and favored harmful algal bloom-forming organisms. Climate-induced drivers also affected the human component of the social-ecological system, preventing fishers from securing a fulltime livelihood and limiting the fishery economic potential. Adaptive responses at multiple levels provided some capacity to address climate change effects, and transformative pathways are being taken to adapt to climate-induced changes over the long-term. Transformative changes were fostered by the local perception of environmental change, shared narratives, sustained scientific monitoring programs, and the interaction between knowledge systems, facilitated by a bridging organization within a broader process of governance transformation. The combination of autonomous adaptations (based on linking social capital and fishery leaders agency) and government-led adaptations were essential to face the challenges imposed by climate change. Our results serve as a learning platform to anticipate threats and envision solutions to a wide range of small-scale fisheries in fast-warming regions worldwide. 相似文献
Neoliberal policies of effort limitation and privatization have reduced commercial salmon and other fishing opportunities available to the coastal, predominantly Alaska Native, villages of southern Alaska. However, there are a variety of circumstances, including the manner in which the current commercial fishery is prosecuted, that lead to surpluses of unharvested salmon, and potentially other species, available in certain areas. This paper will define the concept of “foregone harvests”, discuss the environmental and managerial conditions that lead to “foregone harvests” and describe the possibilities such conditions create for the development of small-scale, local and community-based fisheries. Case studies of possible Huna Tlingit (Hoonah) and Kaigani Haida (Hydaburg) salmon fisheries will be presented. Alternative arrangements of salmon fisheries and institutions in southeast Alaska are presented through case studies of the villages of Yakutat and Metlakatla. These examples demonstrate how such fisheries could be built on local and traditional knowledge, as well as currently used subsistence technologies resulting in new economic opportunities compatible with local cultural patterns and interests and buttressing local identities and commitments. 相似文献
Political acceptability is an essential issue in choosing appropriate climate policies. Sociologists and behavioural scientists recognize the importance of selecting environmental policies that have broad political support, while economists tend to compare different instruments first on the basis of their efficiency, and then by assessing their distributional impacts and thus their political acceptability. This paper examines case-study and empirical evidence that the job losses ascribed (correctly or incorrectly) to climate policies have substantial impacts on the willingness of affected workers to support these policies. In aggregate, the costs of these losses are significantly smaller than the benefits, both in terms of health and, probably, of labour market outcomes, but the losses are concentrated in specific areas, sectors and social groups that have been hit hard by the great recession and international competition. Localized contextual effects, such as peer group pressure, and politico-economic factors, such as weakened unions and tightened government budgets, amplify the strength and the persistence of the ‘job-killing’ argument. Compensating for the effects of climate policies on ‘left-behind’ workers appears to be the key priority to increase the political acceptability of such policies, but the design of compensatory policies poses serious challenges.
Key policy insights
Public perception of, and support for, climate policies is substantially reduced in the presence of large negative shocks, especially job losses.
Climate policies can be perceived as negative for employment, especially in areas where polluting industries represent a large share of employment and in occupations and sectors already damaged by globalization and automation.
Policymakers should distinguish between small and large distributional effects of climate policies, and find the appropriate combination of revenue recycling schemes, industrial and retraining policies as well as compensation packages to increase the support for such policies.
The Paris Agreement and the Sustainable Development Goals (SDGs) set ambitious targets for environmental, economic and social progress. Climate change mitigation policies play a central role in this process. To maximize the benefits and minimize the negative effects of climate change mitigation policies, policymakers need to be aware of the indirect and often complex social and inequality impacts that these policies may have and the pathways through which these impacts emerge. Better understanding of the distributional and inequality impacts is important to avoid negative social and distributional outcomes as countries ratchet up their climate policy ambition in the post-Paris context. This paper synthesizes evidence from the existing literature on social co-impacts of climate change mitigation policy and their implications for inequality. The analysis shows that most policies are linked to both co-benefits and adverse side-effects, and can compound or lessen inequalities depending on contextual factors, policy design and policy implementation. The risk of negative outcomes is greater in contexts characterized by high levels of poverty, corruption and economic and social inequalities, and where limited action is taken to identify and mitigate potentially adverse side-effects.
Key policy insights
The risk of adverse social outcomes associated with climate change mitigation policies, including worsening inequality, increases as countries ratchet up their ambition to meet the Paris Agreement targets. Many policies that have so far only been piloted will need to be up-scaled.
Negative inequality impacts of climate policies can be mitigated (and possibly even prevented), but this requires conscious effort, careful planning and multi-stakeholder engagement. Best results can be achieved when potential inequality impacts are taken into consideration in all stages of policy making, including policy planning, development and implementation.
Climate change mitigation policies should take a pro-poor approach that, in best case scenarios, can also lead to a reduction of existing inequalities.
