Higher temperatures, wildlife extinction, rising sea levels, droughts, floods, heat-related diseases and economic losses are among the consequences of climate change. Climate change disproportionally affects the poorest and most marginalized communities living in vulnerable regions, among them indigenous peoples, whose livelihoods depend on natural resources. 

Bangladesh is one of the world’s most vulnerable countries affected by climate change. During the monsoon period, the Haor region of Bangladesh becomes completely inundated with 4-8 metres of water for around 6-7 months of the year. Flash fl oods are common, and in some years 80-90 per cent of crops are lost because of extreme weather events. The situation is expected to worsen as a climate
change-related shift towards pre-monsoon rainfall is coinciding with the paddy rice pre-harvest period. This severely affects food output in the Haor, which provides up to 16 per cent of national rice production.

Prendre en compte les priorités des petits exploitants en matière d’adaptation

Climate change is the most compelling challenge facing the world today. It affects rural smallholders across the developing world, with effects that pose a grave threat to their own, and to the world’s food security.

La pêche et l'aquaculture apportent une contribution importante à la sécurité alimentaire et aux moyens de subsistance, tant à l'échelle des ménages qu'au niveau local, national et mondial. Toutefois, si la production aquacole se développe rapidement à l'échelle planétaire, en particulier en Asie et en Afrique, nombre de pêches à travers le monde sont en grand danger du fait des pressions anthropiques, notamment la surexploitation, la pollution et la modification des habitats.

​Le Groupe intergouvernemental sur l’évolution du climat (GIEC) a soulevé un dilemme difficile entre développement agricole et atténuation des changements climatiques.
