The main water-related risks for Asia according to the IPCC
heat stress, storms and extreme precipitation, flooding, landslides, air pollution, drought and water scarcity. These risks are amplified for those lacking the essential infrastructure and services or living in exposed areas. Climate change impacts are projected to slow down economic growth, make poverty reduction more difficult, further erode food security, and prolong existing and create new poverty traps, the latter particularly in urban areas and emerging hotspots of hunger. Climate change is also projected to increase the displacement of people, especially those who experience higher exposure to extreme weather events, particularly in developing countries with low income.
In their latest assessment report, the IPCC has several key messages on water-related challenges at the global and regional level. Below we highlight some of the key risks identified by the IPCC for Asia. 121 Key regional risks include increased flood damage to infrastructure, livelihoods and settlements and increased drought-related water- and food-shortages, the latter already a medium risk in the near term (2030–2040). Climate change is projected to reduce renewable surface water and groundwater resources in most dry subtropical regions, intensifying competition for water among sectors, and to undermine food security especially in rural areas,
which are expected to experience major impacts on water availability and supply, food security, infrastructure and agricultural incomes. There is large agreement between models that wheat, rice and maize production will decline increasingly towards the end of the century if adaptation measures are not implemented, even with moderate climate change. If global temperature increases by about 4°C or more above late 20th century levels, climate change combined with increasing food demand would pose large risks to food security globally.
Urban areas are also increasingly at risk from climate change, including risks associated with
