SPREAD OF THE DESERT
The spread of the desert is threatening specific species of the food crop since time immemorial. Therefore, there is aneed for the forest coverage to be increased. Trees will serve as the natural sink of carbon thus will control the greenhouse gasses effect. This enables crop growing since the control of carbon gases in the atmosphere helps gives conditions favourable for crops in general. According to research done by scholars, it is possible for greenhouse gases to deteriorate the growth of crops since carbon gases combine with the moisture in the atmosphere which eventually lead to acid rain. In the end, the acid rai lowers the pH value of the soil. Similarly, destruction of the food crops by the strong winds can be as well controlled by the afforestation program called agroforestry. Crop species like coffee do well under agroforestry program and they at as wind breakers in the farm (Ripple et al.2013).
Crop diversity
It is evident that the ultimate result of the climate change is crop failure for particular species of crops and this will lead to food shortage. Therefore, farmers are advised to embrace diversity and cultivate those crops that can easily cope with the present state of the climate to avoid food scarcity. This may be practiced through intercropping in the entire process. The approach will also help in the controlling of the pests and diseases of the crops that have emerged as a result of the change in the climate. Intercropping of Napier grass with maize plantation can effectively assist in the control of pests and diseases for this particular crop.
Conclusion
From the research above it can be deduced that climate change is likely to have a significant impact on the food security of a particular region Therefore, there is need to keep vigilant on the climate stability probably through the human activities that we take part in that might have an adverse impact on the entire climate. For instance, the increase in temperature that is under the projection, changes in the patterns of the precipitation, changes in the extreme weather events and finally reduction in the availability of water may results into the reduced productivity in agriculture. Increase in the frequency of extreme weather conditions and their severity will always interrupt the delivery of the food generated from the food crops (Bajželj et al. 2014).
From an international perspective, the issue of climate change should be collectively addressed by all the states. The growth rate in aggregate productivity of the crops to 2050 will just continue to be under the control of the technologies. This will be done along with the modern methods of farming to meet the ever-increasing food demand in various parts of the world. In case there are no proper measures put in place in ensuring that the impacts of the climate on food crop production, there is likely to be a crisis.
The decreasing crop yields and the population increase is likely to put excess pressure on the already system of the food production which is fragile. This is one of the reasons why experts have warned that Africa is likely to suffer from over 13% of her population dying from malnutrition diseases. In case, such a situation presents itself then over 65% of the workers will lose their employment. This is because there are those who are employed either directly or indirectly by the agricultural sector.
