![Figure 7; Selected key impacts for Africa.” 23. The natural variability of ramfall and temperature are the main climatic factors behind variability in agriculture.*’ Any change in climate variability will therefore have an impact on food production, with both positive and negative impacts on food security.” Dryland and rain-fed agriculture are the mainstays in tropical regions. In these regions crops already grow at the limit of their temperature tolerance and yields are likely to decrease with even a small increase in temperature.” More frequent droughts will also reduce crop yields in many parts of the world. But in developed countries, where multi- cropping and irrigation are used, climate change could increase yields. In Bangladesh, the delta’s high fertility has attracted many farmers; more than eighty per cent of the population in the delta depend on the land for a living. But, as flooding becomes more frequent, soil salinity is increasing. Ultimately, people will be displaced not only by rising sea levels and more frequent floods but by a loss of their livelihood.” The distribution of pests and vector-borne diseases could be extended into previously unaffected areas.” Identifying winners and losers from climate change is difficult because of a number of variables, most important of which is the capacity to adapt.
