Conteúdo: | Both conceptual and data problems exist when developing simulation models of soil conservation systems for the humid tropics. However, the time is ripe for soil scientists, agronomists and economists to pool their expertise to develop such models. Simulation models may be constructed from data collected from a variety of sources, and hence progress can be rapid; this feature represents one of the chief advantages of simulation methods (Angus et al., 1974), especially for regions which do not have a long history of agricultural research-a feacture of many of the food crop producing areas in the humid tropics. Often these are the same regions where the pressures on agricultural land are greatest, where the productivity of land and labour is declining (Lagemann et al., 1976), and where the threat of erosion is greatest. In such regions the continual demand for more productive and profitable crop production systems can make life very difficult for agricultural researchs relying on field and laboratory methods. THe increasing avaibility of computer systems should enable these researchers to complement more traditional research methods with simulation procedures. THis  approach offers the possibilities of: a) increasing the number of new cropping systems that may be examined for a given bundle of research resources; b) reduncing the time taken to obtain information on system performance under varying economic and weather conditions; c) markedly reducing the time and research resources required to examine the long-run...
