Description:
This is a paper on reclamation of lowland tropical forests. It argues that due to rapid population growth, grass fallow is increasingly the choice of subsistence agriculturalists. When fallow systems are shortened, weed growth explodes and soil fertility declines which result in soil losses and nutrient depletion. Thus, the length of the fallow period becomes a critical factor for the long-term sustainability of these temporarily cleared plots.

Description:
This is a paper that tries to improve the debate over the soil-degradation consequences of developing-country agriculture on several fronts. First, Part II notes some inadequacies in recent writings on soil degradation trends. Part III re-thinks the requirements for a good empirical test of how agriculture and the soil really interact over the long run. That sets the stage for new historical soil data from China and Indonesia, two countries on which much of the soil-degradation debate has long centered.
