This study analyses the sustainable development in terms of access to basics services, water resources management and external support from Donors. 103 countries are analysed according to 22 variables that include the access to basic services, urbanisation process, uses of water resource, freshwater availability, governance and Official Development Assistance. The measure of Human Development has progressed for all countries except one, during 1995-2010 period. Countries are clustered in 5 reference profiles, where profiles 4 and 5 are considered the poorest and mostly include African countries. The mid-term changes concern 16% of the countries, where most of them are related to governance and Development Assistance aspects. 5% shifts are temporary changes due to the country specificity. Changes from or to the profiles 4 and 5 are deeper analysed providing potential explanations.展开更多
