A group of scientists under the leadership of Andy Challinor from the University of Leeds in the UK stated that within two years, climate change will affect the corn crop in Africa, and about a decade later, the impact of global warming will have an impact on many cereal varieties. These climate scientists fear this could lead to famine in Africa and food shortages in the rest of the world.
The researchers explained that with the increase in mean annual temperature on the continent, the future fertility of different plants in Africa will be reduced during the period during in which they grow. This means that the harvest will begin to produce less accumulated biomass, and this naturally has a negative impact on how abundant the crop is. As shown by the climate models developed by experts, in the next 10-30 years, the affect on the fall harvest will be so significant that it will affect the entire world. The reduction in greenhouse gas emissions, in all likelihood, will not stop this process will not stop, but will only slow it down a little, the researchers note.
One of the chosen answers for the problem by the scientists was a call for the creation of new varieties of corn and cereal. However, in order for this approach to be effective, researchers will have to act quickly. To date, the breeding of new varieties is most often a very slow process, while global warming, especially in Africa, may soon play a negative role.
Scientists presented the results of their study in the scientific journal, Nature Climate Change.
