Global water demand will increase dramatically even if agricultural production practices become more water-efficient (OECD, 2012). This increase will be driven mainly by growing demand for electricity generation and manufacturing in emerging markets such as Brazil, China and India (Figure 12.11). Groundwater depletion is projected to become a severe challenge for agriculture and urban water supplies, and though water supply should improve overall, it appears likely that more than 240 million people will not have access to drinking water by 2050 (OECD, 2012). This does not bode well for disaster risk reduction.
