The emissions of greenhouse gases together with other anthropogenic activities has caused a change in global climatic conditions with corresponding negative effects on agricultural productivity, biodiversity and other socio-economic indices. Studies reveal that the impacts of climate change are felt most severely by the vulnerable, who have fewer adaptive capacities. In Africa, for example, little is known about local narratives on the ‘causes’ of climate change, and how such narratives influence climate change coping and adaptation strategies in specific local settings. Where do the ‘local’ and the ‘global’ intersect in the search for effective coping measures – and do they? Using a qualitative approach, this paper reveals how local conceptions of climate change appear to be rooted in ‘politics’ and spiritual forces. The paper highlights not only the major points of divergence between local interpretations and ‘Western’ conceptions about climate change, but also important areas of convergence between the two ideational domains. 相似文献

Recent government legislation, which calls for the eradication of trout from ecosystems where they may cause harm, could damage the tourism appeal of many South African catchments. However, no South African studies have tried to quantify the economic impact of removing trout from rivers and streams. This study aimed first to value the Rhodes trout fishery, North Eastern Cape, South Africa, and second to assess whether the trout fly fishing industry in Rhodes could form the foundation for the implementation of a local economic development initiative. Overall, the study found that the trout fishing industry directly generates approximately R5 658 240 per annum, and sustains a minimum of 39 direct job opportunities for the community of Rhodes, and can therefore provide the impetus for the creation of a tourism-based local economic development programme. 相似文献

This paper provides evidence on the economic impact of climate change on agriculture in the Central Highlands of Afghanistan by exploring the climate sensitivity of crop net revenue per unit of land. A Ricardian model and a novel 2017 dataset for 1502 farmers in three central provinces along with 34 years of weather information are used to study the impact of variations in seasonal precipitation and annual temperature. The findings suggest a significant and nonlinear effect of climate factors on crop net revenue. The impact of seasonal precipitation is found to vary across space and time. The effect of increased annual temperature is found to be generally positive and significant—both statistically and economically. The predicted impact of future climate change is largely beneficial, mainly due to warming. 相似文献
