EFFECTS OF AGRICULTURAL PRACTICES ON THE POLLUTION OF SURFACE WATER IN BENIN REPUBLIC
Journal Title: Larhyss Journal - Year 2017, Vol 30, Issue 30
Abstract
The contamination of surface and groundwater in a watershed is mainly due to poor agricultural practices. These include excessive use of fertilizers for high yields, irrigation practices and the use of pesticides. These practices can lead to nutrient flows, chemicals, and pathogens to water resources and disrupt ecosystems. Benin Republic has diverse agricultural areas. Massive use of inputs and pesticides in agriculture, especially in cotton culture is an important source of chemical pollution. Sediments, aquatic organisms and especially vegetables of cotton areas of north Benin are contaminated with chlorinated pesticides. In gardening’s perimeter, the heavy metals are found in soil and water. There is also a bacterial pollution due to the composition of compost used in these areas. To remedy this situation, the financial and material resources available need to be strengthened substantially to enable training of farmers and to allow the development of appropriate techniques to prevent and. This article analyzes the available scientific knowledge regarding the various existing agricultural practices in Benin Republic and suggests possible solutions to reduce the risk of contamination of this aquatic ecosystems.
