s:1191:"%T The potential of agroforestry for soil conservation: Part 1 - erosion control 
%A Young A 
%X Soil conservation in its broader sense covers erosion control, the maintenance of soil fertility, and thus sustainable land use. This Working Paper, which forms Part I of the review as a whole, covers agroforestry in erosion control. Trends in soil conservation research and policy are reviewed, and assessed with respect to their significance for agroforestry. Attention is given to predictive models, the importance of soil cover, land evaluation, effects of erosion on land productivity, and economic and policy aspects. The impact of agroforestry on erosion is reviewed with respect to effects of trees on the causative factors of erosion, and examples of agroforestry practices in erosion control. The different lines of evidence are summarized in terms of the probable effectiveness of specified agroforestry practices as a means of erosion control. The combination of a high apparent potential with sparse data means that there is a clear need for research. The objectives and design of research are discussed. The conclusions from the review are given in the Summary which follows.
