Abstract

Land erodibility assessment in developing countries is often constrained by the lack of a methodology capable of assessing, from limited and often incomplete soils and climatic data, the potential erosion risk of agricultural lands. This book describes the Land Erodibility Assessment Methodology (LEAM) designed primarily for use in developing countries. LEAM assesses the potential erosion risk of lands in quantitative and operational terms by using information contained in soil surveys based on Soil Taxonomy. Assessment of potential erosion risk is based on three land characteristics: 1) slope hazard, 2) rainfall erosivity risk, and 3) intrinsic soil erodibility. Each land characteristic is subsequently defined by other land characteristics such as slope steepness and length, soil moisture regime, and particle-size class and mineralogy class. The LEAM rating framework provides basic information as to whether a given land has a certain potential risk,and describes the agricultural limitations associated with the risk
