Wastewater Use in Agriculture- A Case Study in Periurban Area of Mymensingh District

Abstract

Wastewater (ww) is important for the farmers of developing countries for the production of field crops and short rotation plantations (SRPs) during the shortage of irrigation water. Wastewater is rich in nitrogen, phosphorus, zinc and other heavy metals. In principle ww can be easily diverted to farmers filed with a very low cost. Other important matter is the appropriate selection of SRPs for the supply of firewood to farmers and the SRP will reduce the deforestation rate in the country by supplying biomass for firewood. Recently the authors conducted field works in some municipalities to know the peoples interest for ww and SRPs use in Bangladesh. This study reveals that during the period from November to May, there is an acute shortage of water and ww will be the only source of water to use in crop cultivation and SRPs production in Bangladesh.
