In Bangladesh, the intensification of agriculture is indispensable due to its ever increasing population, the food security needs, and land scarcity. Severe agro-climatic events (e.g. flash floods, seasonal water scarcity and salinity intrusion in coastal land) pose further difficulties to crop production. To meet the growing demand of food under these harsh conditions, farmers are using a variety of pesticides indiscriminately; a sharp increase of their use was observed during the last decades. The government of Bangladesh fosters the pesticide use to amplify the agricultural frontiers and to increase output per acre of land. Residues of pesticide applied on agricultural land may enter into the aquatic environment through drain, runoff and spray drift, thereby contaminating this environment. Hence, this PhD thesis aimed to investigate the human health issues and ecological risks on aquatic ecosystems posed by the large scale use of pesticides in Bangladesh.
By September we will present an overview of SENSE dissertations on this page, with links to the full texts of the dissertations.
