Climate Change Could Raise Food Shortage Globally: Study

The purpose of the article “Climate Change Could Raise Food Shortage Globally: Study” is to discuss the extreme consequences that Climate Change can have on our food supply. In the article, the author explains that in the near future, a global shortage in food could occur due to Climate Change. Climate Change is an environmental issue that has only been worsening as it continues to result in extreme weather changes. Richard Betts, a University of Exeter professor, predicts that Climate Change is expected to cause many more extreme rainfalls as well as droughts. He also explains how the extreme weather changes will have different effects on different countries. Climate Change is projected to cause more intense rainfalls, consequently leading to floods which will halt food production. In addition, with an increase in temperature, Climate Change is also projected to cause more droughts which will consequently harm agricultural processes. Extreme weather changes like floods and droughts which are ultimately caused by Climate Change will only put our food production processes at risk. With food production processes at risk, a shortage in food around the world is to come.


Climate Change is an environmental issue that is only worsening and is almost impossible to stop. However, us humans have a great effect on Climate Change and we can certainly take the necessary steps required to lessen its impact on our environment and on our lives. For example, we can make sure to power our houses with renewable energy sources. In addition, we can use LED lightbulbs which use far less energy than regular lightbulbs. It is very difficult to completely eliminate Climate Change, however, making small changes like the ones previously stated as well as others can definitely go a long away and can make a difference.




I have chosen to respond to your summary, as food shortage and increased vulnerability of food sensitivity as a result of climate change is a topic that is not talked about as much as others; when thinking of climate change, most will automatically think of global warming affecting wildlife habitat, along with the intense heat melting ice, thus rising sea levels. With that said, the extreme rainfalls and droughts caused by climate change will, in fact, affect crops and agricultural processes. However, crops are not the only factor that is affected by this, but fisheries are also affected by this issue, due to overexploitation and pollution. Though, one contradiction is the fact that yes, climate change does affect food production, but food production itself partially contributes to the causes of climate change. That being said, food production is one of the causes of environmental degradation and is a highly significant emitter of greenhouse gases into our atmosphere; agriculture contributes to approximately 15% of all emissions and may be as high as 30% if taking into consideration other food production methods (Grantham Research Institute & Clark, 2012, p.1). Therefore, there seems to be some sort of ironic cycle connecting both food production and climate change.

In conclusion, I do agree with what you have said about us, humans, having to make changes in our daily lives in order to make our environment healthier by the second. In order to help something like climate change stop, we need to take measures in our own hands for the planet we live on; food production could be completed in healthier and less harmful ways, thus improving our climate change and other factors damaging our ecosystems. Consequently, in return, vulnerability of food sensitivity will decrease and the cycle will continue non-viciously.

I chose to comment on your summary because I was interested in knowing the extent of the damage caused by climate change on the depletion of food supplies around the world. I also want to acquire more knowledge on the living conditions of people in developing countries in order to raise awareness on issues such as this one, which we are fortunate enough in Quebec to not experience. I found many examples of countries that are currently going through climate change-induced food shortages just as you pointed out. For instance, according to a 2012 UN report, “one in four households in sub-Saharan Africa cannot access adequate food”. (Masipa, 2017) Unfortunately, things are only getting worse as South Africa is described as being a vulnerable area to the effects of climate change. (Masipa, 2017)
In 2007, the Intergovernmental Panel on Climate Change predicted that “agricultural productivity will decline from 21% to 9% by 2080 due to climate change in sub-Saharan Africa” (Masipa, 2017) Another example is Bangladesh, a poor and very populated country, where floods due to the sea-level rise happen often, as “[about] 10 percent of [the country] is barely one metre above the sea level.” (Gulsan & SM, 2013). In fact, the annual rate at which the sea level increases in Bangladesh is more than the double of the global rate. (Gulsan & SM, 2013) The shrinking of the coastal land is a huge problem for the agricultural sector, on which “almost 70 percent of country population depends [...] for their livelihoods.” (Gulsan & SM, 2013)

I agree with you that we as individuals should make changes in our daily lives to reduce the effects of climate change. I also think it is important to raise awareness about this issue by talking about it to our friends and further educating ourselves on the extensive impacts it produces around the world.
