Unit 1:
|
World food production varies by several percent from year to year, largely as a result of weather conditions. Some agricultural regions are more sensitive to changes in climate than others. The most sensitive regions are often in the developing countries where less advanced technology is available to minimise the impact of droughts and floods and where soils, terrain and climate are less suited to agriculture.
A key task facing those concerned with conducting climate impact assessments is to identify those regions most likely to be vulnerable to climate change. This will, hopefully, allow countries to adapt so that the impact of climate change is minimised.
