Question

Explain the dependence of agriculture on the available water.​

Answer 1

Answer:

Water is a critical input for agricultural production and plays an important role in food security. ... Currently, agriculture accounts (on average) for 70 percent of all freshwater withdrawals globally (and an even higher share of “consumptive water use” due to the evapotranspiration of crops).

Answer 2

Answer:

Water is a critical input for agricultural production and plays an important role in food security. Irrigated agriculture represents 20 percent of the total cultivated land and contributes 40 percent of the total food produced worldwide. Irrigated agriculture is, on average, at least twice as productive per unit of land as rainfed agriculture, thereby allowing for more production intensification and crop diversification.
