Abstract

Abstract In this paper the effect of fertile top soil degraded by environmental factors such as acid rain and wind on crop yield is studied by considering a single-sector economic growth model. It is shown that if these environmental factors continue to increase without control, the fertile top soil depth tends to zero and consequently the crop yield becomes negligible. However, if suitable measures are taken to fertilize the top soil and to control the acid rain, the crop yield may be maintained at a desired level.
