Climate change: Agriculture in danger

Marine Gauthier, Hina Idris and Audrey Rose Lussier 

Our world is hugely affected by global warming. It affects human health, forests, oceans and so on and so forth. But one of the impacts that really affect our daily life negatively concern agriculture. One of our basic need is to eat, therefore, negatives effects of climate change on agriculture is bad for human’s healthy consummation of food. Flooding and droughts are two main direct consequences of climate change that affects crop yields and breeding.

 

In the first place, flooding affects seed’s season and the crops. Flooding causes lack of oxygen in soils which leads to the increase of disease infections that put crop stands at a high risk. Then, all the agriculture soils that are flooded prevent the farmers to harvest the seeds. Which leads to food price increasing, reduce food availability and more demand of food than there is to supply the population. A study shows that in order to feed all the world-wide population in the next few years, we should increase world food production by at least 30% to achieve global demand. The thing is we probably won’t be able to sustain that much food because of the climate change and the impacts that we point out. Extreme events like droughts and floods could reduce as much as 50% of the average yields during growing condition which is a lot. A good example happened this year in Canada and in certain part of the United State while many farmers haven’t been able to grow wheat because of the rain that occurs during the season used to sow. This real event will probably repeat during the coming years over and over again if we don’t start paying attention and being careful about the global warming. Also, the global hunger will certainly persist and expanse. Droughts cause also an inability for the seeds to grow because of a lack of water, which leads to dry fields and a lot of money from farmers for irrigation.

 

Furthermore, heat waves are causing extreme temperature that attracts many species of insects to flee away and migrate into some new countries which unbalance the ecosystem of those. They are contributing to the decrease of the crops yields because they’re eating them. The simple reason of this event is our pesticides are not able to repel them. Also, extreme heat waves can reduce overall harvest by 10% over 50 years. Because in North America we use the same methods of farming for a large area, if one part of the field is affected than the chances that the entire field will be damage are high. If the government don't improve agriculture systems and don’t put efforts in order to succeed to do this than our agriculture methods won’t resist the shocks that climate change brings.

 

Even though, climate change has many bad repercussions on agriculture, scientist found that carbon dioxide has some good impacts on plants and crops. A research showed that carbon has the capacity to fertilize plants and also contributes to the health of crops. This is a very interesting fact. Unfortunately, global warming in general is far from helping the environment!
