P1MC – the Program One Million Cisterns for Drinking Water and P1+2 – the Program One Piece of Land and Two Types of Water are: community based programs of “Mainstreaming Rainwater Harvesting” in the context of participative and integrated land and water management in the rural area of SAB.

Drinking water for the families 800,000 cisterns of 16,000 L for drinking water have been already constructed by the organized civil society with money from the government in the last 15 years. 578,689 cisterns alone by ASA – Association of Semi-Arid Civil Society Organizations. Furthermore, since 2012, the Ministry of National Integration is constructing PVC cisterns, provided by a multinational company, but criticized because of technical quality problems and lack of community involvement.
