Poor drainage is found on about 11.3% of agricultural land in Latin America where physiography promotes flooding, high groundwater tables, or stagnant surface water (waterlogging). Waterlogging drastically reduces oxygen diffusion into the soil causing hypoxia which is the main limitation that re...

The logic of voluntary contributions to an indivisible public good is studied, firstly in a simple game-theoretical framework, then in an empirical investigation of a case of watershed development in the Ethiopian Highlands. The former approach emphasises the difference between the problem under ...
