Farmers’ Perceptions of Climate Change and Agricultural Adaptation Strategies in Rural Sahel 总被引:17,自引:3,他引:14
Farmers in the Sahel have always been facing climatic variability at intra- and inter-annual and decadal time scales. While
coping and adaptation strategies have traditionally included crop diversification, mobility, livelihood diversification, and
migration, singling out climate as a direct driver of changes is not so simple. Using focus group interviews and a household
survey, this study analyzes the perceptions of climate change and the strategies for coping and adaptation by sedentary farmers
in the savanna zone of central Senegal. Households are aware of climate variability and identify wind and occasional excess
rainfall as the most destructive climate factors. Households attribute poor livestock health, reduced crop yields and a range
of other problems to climate factors, especially wind. However, when questions on land use and livelihood change are not asked
directly in a climate context, households and groups assign economic, political, and social rather than climate factors as
the main reasons for change. It is concluded that the communities studied have a high awareness of climate issues, but climatic
narratives are likely to influence responses when questions mention climate. Change in land use and livelihood strategies
is driven by adaptation to a range of factors of which climate appears not to be the most important. Implications for policy-making
on agricultural and economic development will be to focus on providing flexible options rather than specific solutions to
uncertain climate. 相似文献

The invasion of Salvinia molesta in the Lower Senegal River Delta in Mauritania and Senegal in 1999 posed a serious threat to the socioeconomic conditions of the local people as well as to wetland biodiversity. Eventually, an effective biological control of S. molesta was obtained by means of the weevil Cyrtobagous salviniae, which was introduced in the river in Senegal and Mauritania in May 2000 and in Senegal in April 2001. In October 2001, it became apparent that the weevils were doing a magnificent job. The color of the plants was turning from green to dark-brown or black, and subsequently the plants started to sink to the bottom. Detailed monitoring of the dispersal of C. salviniae in November-December 2001 confirmed the visual observations of the outcome of biological control. In April 2002, it could be concluded that S. molesta was no longer a problem in the Senegal River. 相似文献
