Agrochemicals use in horticulture industry in Tanzania and their potential impact to water resources

Abstract

The purpose of this review was to analyze the existing information on the use of agrochemicals (Fertilizers and Pesticides) in the Tanzanian horticulture industry especially the Northern regions and their potential to impacting water resources. Reports from studies done in Northern Tanzania have indicated the presence of significant levels of pesticides, phosphates, and nitrates in surface and groundwater. It is apparent that most of the horticultural farms in Northern Tanzania are located on gently sloping land adjacent to water bodies. The use of certain agrochemicals like pesticides and fertilizers has been associated with contamination of the environment and potential impacts to water resources and affect people.
