Climate Change On Food Security Environmental Sciences Essay

Roughly a billion people around the world live their life in constant fear of what to eat at night or how to provide for their familys and humanitys failure to give them better improvement has been one of its most uncontrollable flaws. This research paper talks about the negative effects of climate change on food security. Long term change in the earth’s climate especially a change due to an increase in the average atmosphere is what we call climate change, and many people are affected by it right now all around the world. Food security is a scenario that prevails when all individuals, at all times, have physical, social, and economic access to adequate, safe, and healthy meals that fits their nutritional needs and meals choices for an effective and healthy life, but the negative effect, the adverse external effect changes these situation for people. Climate change has severe significance for food production and availability of food all over the world. Trying to view the overall impact of climate change on our food can be tough. Constant Changes in the climate change like, drought and floods could pose as a challenge for farmers and fishers. Right now climate change is already having a great influence to the quality and to the quantity of food produced causing it to increase malnourishment. The topic of climate change and food security is a very sensitive issue to touch upon since food is one of the most important parts of our daily life. Imagine a year where there is no rainfall, or a cold weather in a wrong time of year, or even floods, they all can have a great deal of impact on local crop yields and livestock production. However not everyone around us is aware of these issues, therefore this paper informs people to realize that climate change can affect every part of food production like the impact of climate change on food availability. This paper manly focuses to inform people about the changes that climate change can bring to food production and what are the consequences of not being able to produce food.

Impacts on Food Production and Availability

Joseph Schmidhuber and his associates examined the effect of climate change on food security all around the world. The article reviews the impact of climate change and how it has a big impact on food production and food price. Climate change is most definitely to affect the manufacture of food in several ways. The more known impact of climate change on the volume and quality of food produced is the effect of weather patterns that are constantly changing over time, in addition these changes are varied based mainly on location and the effect might be greater in different populations (Schmidhuber et al., 2007). Worldwide the weather conditions are to become more unreliable than present, with the increase in the rate and asperity of intense events such as cyclones, floods, hailstorms, and droughts. By providing greater changes in crop yield and local food resources and greater threats of landslides and erosion damage, they can adversely affect the balance of foods resources and thus foods security (Schmidhuber et al., 2007).

Liliana Hisas (2011) looks at the issues by assessing and collaborating population growth, food development, nutrition and undernourishment, and connecting these factors to climatic change, to measure the effects on food development. Recuperating more area fit for farming production is unlikely. Hisas’s research has shown that globally the amount of area that is useful for farming will remain the same in 2080 as it is today, because increases in useful land in some regions will be mostly balance by failures in others. It is the other two elements, water and different climate condition’s which would most significantly affect food development globally due to climatic changes. The expected effects of climatic change on food development are farming in low-latitude areas, due to reduced water accessibility and adverse water balances; and water resources in mid-latitude and dry low-latitude areas, due to changes in rainfall (Hisas, 2011: 16). Wulf Killmann (2008) investigates in the article paper a wider view and examines the multiple effects that global warming and climatic change could have on food systems and food security. It also explains the adverse effect of not having enough food and not being able to produce food to feed a nation. Greater temperature ranges lead to heat pressure for vegetation, improving sterility and decreasing overall development. Greater temperature ranges also increases water loss from vegetation and dirt, enhancing water supplies while decreasing water accessibility. In many locations, growing seasons are changing, environmental locations are moving, and rain fall is becoming more unforeseen and not reliable both in its time and its volume. This is leading to greater doubt and increased risks for farm owners and potentially deteriorating the value of traditional farming knowledge such as when to plant particular crops (Killmann, et al., 2008).

Agriculture is important for food security in two ways, it generates the food people eat and it provides the main earnings for 36 % of the globe’s total employees. In the intensely booming nations of Japan and the Hawaiian, this share varies from 40 to 50 %, and in sub-Saharan Africa, two-thirds of the working population still earns a living from agriculture. If farming growth in the low-income developing nations of Japan and Africa is seriously affected by global warming, the earnings of huge numbers of the non-urban inadequate will be put at danger and their access to meals uncertainty will be increased. Effects on the food production will impact food supply at the international and regional levels. Worldwide, higher results in in moderate areas could balance out lower results in in exotic areas. However, in many low-income nations with limited financial capacity to trade and high dependency on their own development to cover food requirements, it may not be possible to balance out problems in regional supply without increasing dependency on food aid. Effects on all forms of farming development will impact the earnings and access to foods. Manufacturer groups that are less able to deal with climate change, such as the non-urban inadequate in developing nations, risk having their safety and wellbeing composed (Killmann, et al., 2008).

To be food secure, a nation, family, or individual needs regular access to adequate food resources. The concept of food stability represents the accessibility and availability to food. Climate uncertainty is an important aspect in a constant food supply. For example, the expected improvement in rate and asperity of intense events such as flooding and droughts can create significant changes in crop and local food resources. In addition, agriculture workers and others who rely on farming earnings in a region where extreme weather activities are increasing would be at high chance of losing their income and, their ability to purchase food (Hisas, 2011: 23). It also will lower the lifestyle conditions of farm owners, fisherman and forest-dependent individuals who are already inferior and food insecure. Hunger and lack of nutrition will increase. Non-urban areas reliant on farming in a weak environment will face an immediate chance of increased crops failing and lack of livestock. Mostly at danger are individuals living along shorelines, in floodplains, hills, dry areas, and the arctic. In general, the inadequate will be at probability of food uncertainty due to lack of resources and lack of sufficient insurance policy (Killmann, et al., 2008). Climate change will have a great effect on all aspect of food security, like food availability, food stability, and food consumption. The value of the many matter and the overall effect of climate change on food security will be different across areas and over time and, most of all, is identified by the overall position that a country has achieved as the effects of climate change has set in.
