| description | Soil erosion hazard in tropical Africa is a serious threat towards sustained productivity. The available basic research information on soil, climate, and land use is rather sketchy and indicates that the severity of the erosion hazard may be attributed to soil characteristics, low soil loss tolerance, and climatic factors that lead to accelerated soil erosion following a change in land use. Researchers in the tropics have yet to establish appropriate methods for monitoring and estimating, precisely and by simple techniques, soil erodibility and erosivity in relation to soil and rainfall characteristics. There is a little information on the soil loss tolerance or acceptable levels of soil loss. |

Les renseignements disponibles provenant des recherches de base sur les caractéristiques des sols, le climat et l'utilisation du sol sont plutôt vagues et ils indiquent que la sévérité de l'érosion éventuelle peut être attribuée aux caractéristiques des sols, à la faible tolérance de ces sols en ce qui concernent les pertes et aux facteurs climatiques lesquels conduisent à une érosion accélérée après modification de l'utilisation du sol. Les chercheurs sous les tropiques ont encore à établir une méthodologie approprié pour suivre et estimer avec précision et par des techniques simples I'érodibilitë du sol et l'érosivité en relation avec les caractéristiques des sols et de la pluie. Il y a peu d'informations sur la tolérance des pertes des sols et le seuil acceptable de pertes en sol. 1981-06 2017-05-23T08:36:10Z 2017-05-23T08:36:10Z Conference Paper https://hdl.handle.net/10568/81171 en fr Limited Access International Association of Hydrological Sciences Lal, R.
