The vastness of the Asian continent gives a different characterization of the arid, semi-arid and dry sub-humid areas of the region, making it equally difficult in formulating a single strategic approach to drought management. It is imperative to make a risk- analysis assessment of the Asian region in relation to the frequency of drought occurrence as well as its severity. Drought is a recurring climatic phenomenon that should be distinguished from climatic change. However, the frequency of drought is certainly affected by climate change. Historical analysis of climatic variations and drought occurrence is very important as a basis for risk assessment. Moreover, existing models of projected climatic change in the above regions as a result of the postulated greenhouse effect should also be used in risk assessment, particularly with regard to possible changes in aridity and drought frequency. Finally, an assessment has to be made of the possible effect of climatic change and drought on desertification, which ought to be exemplified by actual historical cases which can serve as a reference framework and database.

The overall objective of this theme is to enhance preparedness and strengthen institutional capacities to plan for drought preparedness and management with the end view of developing early warning systems and medium-range forecasting methodologies for improving food security.
