Economic analysis of soil erosion effects in alley cropping, no-till and bush fallow systems in South Western Nigeria. uri icon

abstract

  • Presents results of economic analysis carried out in southwestern Nigeria to determine the profitability of alternative land use systems, taking into account the short and long-run impact of soil erosion on agricultural productivity. The fallow systems include 1. two continuous cultivation alley cropping systems with leucaena hedgerows, 2. the continious cultivation no-till farming system and 3. two traditional bush fallow systems. The results shows that where access to new forest land is 'costless', slight yield damage from erosion will not detract significantly from the immediate profit advantage of traditional bush fallow systems, with longer fallow systems, with longer fallow periods
