Quenching the thirst of rapidly growing and water-insecure cities in sub-Saharan Africa

摘要

It is in the water sector that Africa faces some of its more pressing challenges, which are exacerbated with the sprawl of megacities. The gap between water requirements and available water resources is widening. While the urbanization process is still accelerating, acute seasonal and chronic water shortages are already encountered in almost all major cities. Unless the direction is radically changed, sub-Saharan Africa is headed towards an urban water crisis of alarming proportions. Based on city experiences in Africa and comparison to those in India, we draw lessons and suggest response options for tackling urban water crisis risks in Africa.
