Abstract:
The aim of this study to quantify the water footprint (WFP) of crop production, animal’s products and human population for district Prayagraj U.P, India. Assessment of water used in agricultural for food production is essential to scrutinize the dynamic behaviour of crop production and its water footprint. Water consumption and crop productivity form the basis to calculate the water footprint of a specific crop. Water footprint is essential for the quantified total water consumption of crop production. In the present study Water footprint assessment for selected nine crops namely, Wheat, Paddy, Barley, Jowar, Sugarcane, Potato, Bajra, Oilseed and Pulses have been carried out. The research based on assesses water use in these selected crops grown in the study area. Water footprint of paddy production is maximum (5952.38 m³/ton) followed by Oilseed (5142.86 m³/ton), Pulses (4629.63 m³/ton), Jowar (4591.84 m³/ton), Bajra (4591.84 m³/ton), Barley (3214.29 m³/ton), Wheat (2826.09 m³/ton), Sugarcane (478.26 m³/ton) while minimum in Potato (343.14 m³/ton). In this paper the calculation of water footprint for different types of animal products. The following animal categories viz. Cow, Buffalo, Goat, Sheep, Pig and Poultry were also considered. Water footprint of milk production of Cow is maximum (5628 lit/kg) followed by Buffalo (5212.50 lit/kg) while minimum is for Goat (1303 lit/kg). Water footprint for pig meat, goat and sheep meat (mutton) and other meats indicate the large volume of water used for their production. Water footprint of meat from Goat is 13402.29 lit/kg, Sheep 16018.67 lit/kg, Pig 15876 lit/kgand for Chicken 4498.67 lit/kg while water footprint of Egg is 192.80 lit/egg. Water footprint of human is 48.82 m³/capita/year and it includes water used by the people for their life activities as drinking, servicing, bathing and washing our clothes. On an average, water used per capita is 133.75 lit/day in district Prayagraj. Total water footprint of district Prayagraj is 16565.39 m³/capita/year sharing 3281.22 m³/ton of agriculture, 13235.35 m³/animal/year of animals and 48.81 m³/human/year of human.
