At this stage, we performed the vulnerability assessment by using the current status of the basins. In the future, pressures on environment and water resources may become even higher due to the predicted population growth (UN, 2009) and climate change (IPCC, 2007). The total population within these 10 basins is subject to an increase from 1.7 billion people to 2.4-2.6 billion people by the year 20250,depnding on the scenario, according to the gridded future population dataset presented by Grubler et al. (2007). The average annual growth is particularly high in South Asian Basins (0.9-1.2% for GBM and 1.8-2.0% for Indus ) (Table 1).Within Indus Basin the total population is predicted to increase 144-175% by year 2050. For Southeast Asian river basins the annual growth rate is between 0.5 and 0.9% except Salween where the population is predicted to decrease around 14-16% in total (table 1). The growth rate is smallest in Chinese basins varying from -0.1-0.0% in Pearl River to 0.6% in Yellow River (Table 1).
