ASPECTS OF EUTROPHICATION MANAGEMENT IN TROPICAL/SUB-TROPICAL REGIONS

Abstract

In 1981, the UNESCO in association with the IIASA and OECD recognized that tropical/-sub-tropical water bodies may respond differently to eutrophication management techniques than heretofore expected on the basis of temperate lake studies. However, little information on the eutrophication process and eutrophication management appeared to be available in the literature. This paper reports on the results of a survey of the published literature dealing with eutrophication and eutrophication management in tropical/sub-tropical regions, and highlights the modifying effects of seasonality, climate and hydrology on the eutrophication process in these regions. Nevertheless, the causes and correctives of eutrophication do not differ except in degree from those in temperate regions.
