The impact of untreated effluent from dye industries and domestic sewage that are discharged into the irrigation tank in Pandravedu village in South India was assessed through physico-chemical analysis of water samples and focus group discussion with the community. Thirty-six samples were collected from the study area across three seasons and analysed in the laboratory. The irrigation water quality indices computed indicated that the levels of sodium, salinity and hardness exceeded the permissible limits of irrigation standards. Consequently, rice yield had reduced by 40% in the region, thereby affecting the livelihood of the farmers. The colour of fishes in the tank also changed and their consumption contributed to health-related issues in the village.Keywords

Globally, water constraint is gaining increasing public attention as a critical environmental dilemma due to population growth, urbanization, rapid industrialization and expansion and intensification of food production that need to be addressed. Water scarcity is a reality in many areas today, and it is being exacerbated due to climate change creating critical distress in the future. According to the United Nations, the world’s population is expected to grow by one-third to over 9 billion by 2050, demanding 55% more water, while the amount of freshwater will not increase.Full Text
