New York: As the world is facing a severe food crisis, agriculture needs to be reinvigorated to produce enough food to feed the burgeoning global population, UN Secretary-General Ban Ki-moon has said.

"After a quarter century of relative neglect, agriculture is back on the international agenda, sadly with a vengeance," the UN chief said Wednesday in an address at the start of the three-day high-level segment of the annual meeting of the Commission for Sustainable Development (CSD) in New York, WAM news agency reported Thursday.

"The onset of the current food crisis has highlighted the fragility of our success in feeding the world's growing population with the technologies of the first green revolution and subsequent agricultural improvements," he added.

The secretary-general pointed out that productivity growth has fallen, soils have become depleted and less fertile, water shortages have become very common as well as the farmland has been used for other purposes or has been degraded.

"Furthermore, public investments and donor support for agriculture have been declining," Ban underlined.

To breathe new life into agriculture, the UN chief said that a fresh generation of technologies and farming methods will be essential to usher in a second green revolution, one which permits sustainable yield improvements with minimal environmental damage and contributes to sustainable development goals.
