This assay is based on El Nino as a frequent event, the impacts El Nino attributes on South African economy, food security, farm practices and labour relations. It also includes what global warming is, its causes and difference between global warming and climate change. Furthermore, discuss why global warming and climate change effects serve on developing countries.
According to Accuweather (2019), El-Nino is a routine climate pattern that occurs when the sea surface temperatures in the Tropical Pacific Ocean rise above normal level for a long period of time. El Nino can also be described as an unusual warming of the surface of the tropical Pacific Ocean which we can name the ‘warm phase’ of a phenomenon called El Nino-Southern oscillation.
The Pacific Ocean must be warmer than usual which depends on the atmospheric pressure and warm winds blowing over the ocean. The easterly trade winds lose momentum or strength, then turn into westerlies. According to Petersen et.al. (2017:135) this allows the warm water to move irregularly and causes the upwelling of cooler water from deep in the ocean. This reverses the ocean currents along the equator. This also allows moisture-rich air to rise and develop into rainstorms which may result in floods or drought in certain areas. El Nino requires warm water on the Pacific Ocean, atmospheric pressure, trade winds and the rise of moist air to occur.
The El Nino event increases the risk of having heavy rainfall which result in floods and in some places because of reduced rain this result in drought. This does affect the South African economy, food security and labour relations. This type of even can induce dry conditions and decrease water table, raising concerns over water availability. Crops need water and during cropping season, less water made it difficult for farmers to produce goods in time and this resulted is food inflation. Due to dry conditions brought by El Nino some farmers who are involved in mixed farming had a greater challenge because their live stocks also developed certain diseases and could no longer sell then stock without treating them which is expensive and this left most farmers bankrupt and in deep debts. More problems occurred some farm owners had to fire some farm workers because of the debts they had to pay. After El Nino period the South African economy suffers as most farmers lose their jobs and the government gets strained as it must support farm owners financially to provide employment. In some places in South Africa they experienced heavy rain which contributed into creating floods. These floods ruin the infrastructure that would have to be fixed by the government. Some floods wash away crops and fertilizers which end up in rivers and lakes. If the fertilizers end in rivers and lakes this causes eutrophication which makes the aquatic life vulnerable and those farmers involved in marine agriculture cannot sell the fishes and other aquatic animals. According to the journal of sustainable development (2017), South African economy mostly depends on agriculture and resources that are extracted from underground, during El Nino period it becomes difficult for workers to produce goods and sell them in good quality, and this decreases the economy and leads to a lot of unemployment and no food security.
Global warming is the average atmospheric temperature increase on earth, occurs when CO2, pollutants and other greenhouse gases collect in the atmosphere and absorbs excess sunlight and solar radiation. These pollutants and greenhouse gases can trap heat from escaping the atmosphere and this causes the planet’s heat to increase even more, this is well known as greenhouse effect (Wired, 2018: par. 2).
According to Schar & Jendritzky (2004) there is always a risk of hot summers by just observing the emissions of greenhouse gases and using the comparison of observed summer temperatures to whether they are man-made warming or natural warming, while Climate change is created by burning fossil fuels and producing CFCs which add heat to the earth’s atmosphere because they also contain carbon dioxide that is also produced during greenhouse emissions and a is the average weather for a place that occurs at a place over seasons. The climate change is mostly caused by the carbon dioxide and methane. Methane is release from burning fuels and carbon dioxide has natural sources such as decomposition and animal respiration. Deforestation also contributes as one of the causes of climate change because of the reduced amount of plant life available was supposed to turn carbon dioxide into oxygen.
Most developing countries do not have necessary equipment to warn them about upcoming climate change or global warming because these equipment is expensive and because they are major greenhouse gases emitters the countries lack finance to buy clean technology that will adapt to reduce global warming nor climate change. Global warming and climate change serve on developing countries because of various reasons. According to Nancy Bindell, she states that poor people in developing countries feel the impact because of a vulnerable geography and being unable to cope with the damage caused by severe weather patterns. Already some developing countries struggle with access to water, after these weather patterns the people who live in such places are left without necessities and this threatens their live hood. Furthermore, those in developing countries who depend on natural resources for food and income suffer the effects of such phenomenon.
