iii) Pollution of water bodies due to the discharge of industrial effluents, use of pesticides, insecticides, and fertilizers used in agriculture, make the river water hazardous for human consumption.
iv)Inefficient use of water for agriculture is another reason for scarcity of freshwater.Traditional techniques of irrigation cause maximum water loss due to evaporation, drainage, percolation, water conveyance, and excess use of groundwater.
v)Reduction in traditional water recharging areas. Rapid construction is ignoring traditional water bodies that have also acted as groundwater recharging mechanism.
