Drought is a complex natural hazard with social and environmental implications. Satellite information is increasingly used to support decision-makers in preventing or coping with the negative impacts of drought. The integration of local and scientific knowledge to support drought monitoring is still far from being the main procedure in the development of drought monitoring and early warning systems. This study aimed at assessing the degree of convergence between satellite information on the effect of droughts on rangeland vegetation, from time series analysis, and farmers’ perception of drought in North-West Patagonia, Argentina. We characterised the scientific evidence of drought in terms of duration, spatial distribution, most severe years and recovery for the period 2000–2018 by identifying inter-annual NDVI changes. Farmers’ perceptions and experiences of drought were studied with open-ending interviews, with respect to occurrence, duration and recovery for that period. Satellite information matched farmers’ perception of drought at a regional scale, emphasising the value of remote sensing tools in supporting regional policy decision-making. However, farmers’ perceptions and recall of past drought impacts were more diverse than satellite information at a local level, highlighting the need for knowledge integration at finer scales. 相似文献

Anxieties over the potential impacts of climate change, often framed in apocalyptic language, are having a profound, but little studied effect on the contemporary Western urbanscape. This article examines the ways in which current theorizations of ‘ecological gentrification’ express only half the process, describing how green space is used for social control, but not how ecology is used as a justification regime for such projects. As urbanites seek out housing and living practices that have a lower environmental impact, urban planners have responded by providing large-scale regeneration of the urbanscape. With the demand for this housing increasing, questions of inequality, displacement and dispossession arise. I ask whether apocalyptic anxiety is being enrolled in the justification regimes of these projects to make them hard to resist at the planning and implementation stages. The article shows that, in capitalizing on collective anxiety surrounding an apocalyptic future, these projects depoliticize subjects by using the empty signifier, ‘Sustainability’, leading them into an immuno-political relationship to the urbanscape. This leaves subjects feeling protected from both responsibility for, and the impacts of, climate change. Ultimately, this has the consequence of gentrification coupled with potentially worsening consumptive practices, rebound effects and the depoliticization of the environmentally conscious urbanite. 相似文献

Tourism, as all human activities, is dependent on the natural environment and its respective ecosystem services (ES). Different user groups manage and consume these touristic ES differently, resulting in discrepancies and potential conflicts. Despite the urgency to find inclusive local approaches for sustainable development, tourism studies still analyze socio-economic and ecological impacts separately and lack integrated social–ecological approaches to improve foresight in tourism planning. Based on a growing concern regarding the future of Costalegre on the Jalisco coast of Western Mexico, we analyze through interviews, surveys, and participant observation the dependence of tourism on specific ecosystem services and conduct a scenario analysis which shows present and future implications for the social–ecological system. Furthermore, this analysis shows in detail how different scenarios change ES provision and people's livelihoods. Key findings include identifying freshwater provision and cultural ES as the most important touristic ES. At a regional scale, peasants in ejidos are the main ES stewards, whereas high-class tourism facilities constitute important local stewards. Benefits, mainly access to freshwater and the beach, are unequally distributed, provoking conflicts among different ES user groups that may escalate in the near future. Improved communication between all user groups and strengthening of key political actors seem to be the most immediate recommendations to ensure the long term sustainability of this particular region. This work may contribute to improved planning and decision-making as our ES based scenarios are a first step to integrate social–ecological knowledge into improved decision-making. At a local scale, the study reveals the most likely future development options and their social and ecological consequences. It could also serve as a baseline for informed policy making. 相似文献
