Using Crop Models for Sustainability and Environmental Quality Assessment

Abstract

In this article, the question of how various aspects of sustainability can be studied is outlined, with particular reference to ways in which the efficiency of the agricultural research and development process can be enhanced. The role of crop simulation models as useful tools in sustainability research and in the assessment of environmental impact is discussed with reference to some of the collaborative model development and application activities of the International Fertilizer Development Center (IFDC). Despite the fact that much development work is needed on crop simulation models, there are few practical alternatives to address the complex and interactive nature of sustainability issues and environmental impact assessments.
