The study examines the global pattern and impacts of droughts through mapping several drought-related characteristics - either at a country level or at regular grid scales. It appears that arid and semi-arid areas also tend to have a higher probability of drought occurrence. It is illustrated that the African continent is lagging behind the rest of the world on many indicators related to drought-preparedness and that agricultural economies, overall, are much more vulnerable to adverse societal impacts of meteorological droughts. The study also examines the ability of various countries to satis

Using recent advances in modeling climate-related risks and adjusting state of the art catastrophic risk modeling techniques to drought, the study conducts an innovative long-term assessment of drought risks in Andhra Pradesh, India, and suggests strategies to reduce their impact, under several economic, drought management and climate change scenarios. The analysis deepens an understanding of climate risk adaptation strategies, including implications for agricultural and catastrophic risk insurance.

This report describes the development of the near real-time drought monitoring and reporting system for the region, which currently includes Afghanistan, Pakistan and western parts of India. The system is based on drought-related indices derived from high-resolution remote-sensing data (MODIS). The unique feature of the study is the development of regression relationships between drought-related indices obtained from MODIS and AVHRR data, which have different pixel-resolution and optical characteristics. The goal is to make the system available, via Internet, to all stakeholders in the region.
