Although much of our food in the past was grown locally on land that did not require irrigation, would it still be practical to obtain all of our essential food at an affordable price without relying on irrigated land? explain why or why not?

Solution

It may not be possible.

The demand for food will keep increasing due to rising incomes and an additional two or three billion people to feed. Agriculture needs to change to meet that demand. To meet projected demands, the efficiency of water use (crop produced \'per drop\') will need to improve in both irrigated and rainfed zones.

An estimated 870 million people still lack sufficient caloric intake, while a billion or more suffer from micronutrient deficiencies. Another 1.4 billion suffer from overweight or obesity. Progress in reducing poverty and hunger has slowed down in recent years.

Food prices began to rise slowly around 2004 and have fluctuated much since 2007, highlighting the vulnerability of global food supplies and re-vitalizing interest in farming and related issues after a long period of neglect. Global food demand will continue to increase for at least another 50 years – against a backdrop of growing competition for land, water, labor and energy and under threat from climate change.
