Cambodia is one of the most vulnerable countries to climate change because of the predicted changes in temperature and precipitation, the share of labour in agriculture, and low adaptive capacity due to widespread poverty. This study uses climate data from four general circulation models (GCMs) to evaluate the impact of climate change on agriculture in Cambodia by 2050.
An evaluation of crop yields was undertaken as well as exploring potential gains from changing fertiliser levels and using irrigation to compensate for rainfall changes. A survey of 45 communes was also conducted using focus group discussions on agricultural practices.
Results indicated that in response to extreme weather, only 7 to 16 per cent of farmers report changing crop variety and only 20 per cent of farmers report changing planting dates. The report recommends that farmers expand their capacity to adapt and concludes that there is room to increase the use of chemical fertilizers.
