One of the biggest changes to global agriculture is less about the food itself as it is about the water we use to grow it. In some areas, farmers are using freshwater resources - including groundwater - at an alarming rate. The GRACE satellites enable scientists to discover changes to underground aquifers by monitoring changes in the Earth's gravity. In northern India, farmers rely heavily on irrigation to grow crops, and the resulting massive aquifer depletion creates an uncertain future for the region.

The Sudan is not waiting for GMO foods.

They are waiting for the world to get out of their hair and let them keep the profits of their own oil.

The government of India need to help their farmers/people to build water reservoir or little pools to store the water from monsoon rain season for agriculture.

It is clear for me now that we have provided a self-limiting mechanism for the human population.
