Mean winter precipitation will very likely increase in northern Asia and the Tibetan Plateau and likely increase in West, Central, South-East and East Asia. Summer precipitation will likely increase in North, South, South-East and East Asia but decrease in West and Central Asia. Droughts associated with summer ­drying could result in regional vegetation die-offs (Breshears et al. 2005) and ­contribute to an increase in the percentage of land area experiencing drought at any 2 Climate Change in South Asia 21 one time, for example, extreme drought increasing from 1% of present-day land area to 30% by the end of the century (Burke et al.

Also, in general, the projected warming over Asia is higher during northern hemisphere winter than during summer for all time periods. Recent modelling experiments indicate that the warming would be significant in Himalayan Highlands including the Tibetan Plateau and arid regions of Asia. Mean winter precipitation will very likely increase in northern Asia and the Tibetan Plateau and likely increase in West, Central, South-East and East Asia. Summer precipitation will likely increase in North, South, South-East and East Asia but decrease in West and Central Asia.

7 billion and increasing, the region is extremely vulnerable to any climate change that adversely impacts water supply and exacerbates frequency and intensity of droughts. Adaptation, based on choice of judicious land use and adoption of recommended soil/crop/nutrient/water management practices, is an important strategy. Restoring degraded soils and ecosystems and enhancing soil/ecosystem/social resilience is the goal. Sustainable management of soil and water resources can make a difference in successful adaptation to vagaries of changing climate.
