Experts say that the world will need 50 percent more food by 2050 as the population will increase by four million at that time. However, due to scarcity of food production due to climatic changes, a famine would be unavoidable, say experts.

The US study shows that malnourishment is developing widely across the world and the current rate of 18 percent malnourished people in the world is likely to rise to 27 percent in the next forty years.

The studies along the same lines conducted before say that global warming and pollution due to ozone damage affects crops and hence they yield too less which causes malnourishments. Unavailability of nutritious food makes people find artificial substitutes which often damages their health.

The authors of the study also said that the impact of air quality on crops is not recognized widely considering the rise in temperatures all over the world. The major food crops such as rice, wheat, corn and soy are likely to be affected globally which will result in a scarcity of food and lead to a widespread famine.

These four primary crops constitute 50 percent of the food consumed worldwide and hence it is very important that these food crops should be produced in high quantities. The climatic changes impact the production of these crops in different ways. For instance, wheat is impacted by ozone exposure and corn is affected by heat.

However, one solution could be regulating the air quality of the region which will help reduce the ozone content in the region and it can in turn save the crops. However, the regions where air-quality regulations are not in place, crops will be impacted by the air pollution.

‘Ozone is something that we understand the causes of, and the steps that need to be taken to improve air quality”, said Professor Heald of civil and environmental engineering at MIT.
