Agroforestry may not prevent water-logging but it certainly is of great help in these ways: it protects water quality by intercepting sediments and agricultural chemicals. It reduces streambank erosion; it reduces evaporation and plant transpiration and protects certain zones from agricultural runoff. Waterlogging is a global problem.
It affects about one billion hectares and the food security of at least 75 countries. Since the social, economic and environmental costs of farming techniques are high, agroforestry is now the best and most efficient solution to water conservation, quality and maintenance.
