Until recently, soil conservation received relatively low priority in the plans of most developing countries. Priority was generally given to programs of a more spectacular nature or to those that produce quick, obvious returns for the time and money invested. Generally, there was a feeling that land was plentiful and soil erosion was not a serious problem. Over the past decade, this attitude has changed interest in soil conservation. There are a number of reasons for this change in attitude: Soil erosion and other forms of land degradation are now so far advanced in many countries that their effects are obvious to even a casual, untrained observer; Population numbers have grown rapidly in most developing countries, and this is resulting in an acute shortageland in all countries not well endowed with reserves of unused land; Many of the large dams built in the 1960s and 1970s, such as the Mangla and Tarbella dams in Pakistan, are silting up much more quickly than expected because of the high rates of soil erosion in the catchment areas. The effects of drought in Africa over the last decade are now being closely linked with soil degradation; The woldwide interest and publicity given to environmental matters over the last 10 to 20 years are now having their effect, and the public at-large is now much more aware and interested in the protection of the environment than ever before. Turning this interest into effective programs is not an easy task, however. No one is sure how much land is lost annually because of ...
