Climate change is a significant and growing threat to food security—already affecting vulnerable populations in many developing countries, and expected to affect ever more people in more places, unless action is taken beginning today.

This new IFPRI report examines the current and potential strategies to fight hunger. It endeavors to respond to the challenge of growing food sustainably without degrading our natural resource base.

According to this global hunger Index 2012 prepared by IFPRI, India lags behind in improving its GHI score despite strong economic growth. It has analyzed the level of hunger in 120 countries and provides recommendations on how to use land, water and energy for sustainable food security.

As the global population grows and incomes in poor countries rise, so too, will the demand for food, placing additional pressure on sustainable food production. Climate change adds a further challenge, as changes in temperature and precipitation threaten agricultural productivity and the capacity to feed the world

Agriculture is extremely vulnerable to climate change. Higher temperatures eventually reduce yields of desirable crops while encouraging weed and pest proliferation. Changes in precipitation patterns increase the likelihood of short-run crop failures and long-run production declines.
