Explain How Global Climate Change May Affect Food System

The staggering amount of damage by global warming and climate change this year was only a fraction of what global warming and climate change are capable of. Many research conducted all over the world points towards correlations between global warming and increasing tropical storms, and if global warming and climate change aren’t handled correctly they could lead to mortifying effects for the future of the US. Food production is an important part of a functioning society but unfortunately global warming and climate change interrupts it in the

There are many adaptation strategies for farmers to meet the growing challenge of climate change, such as breed and seed selection, water conservation and adjusting the timing of farming operations. These adaptations along with investment in agricultural production are required to maintain and enhance global food security.

Food security is a worldwide concern because of the increases in the price of food, food shortage and other various reasons similar to these. These issues are addressed not only by governments but also by many non-governmental organizations. Clearly the issue of food security is a human right that is of the most importance.

food security is a state where all people in a country have enough access to safe nutritious food to have a sustainable lifestyle. there are three key factors to have a successful food security which include food availability, food accessibility and the ability and resources to use food appropriately and efficiently. all the farmers in the world produce more than enough food to meet the needs of everyone on earth. but there are some major risk factors for the food security such as climate change, armed conflict and water scarcity. but how are these thing affecting our food security?

Due to climate change both the land and the marine distribution is changing, causing numerous problem for human beings. The direct impact of climate change is on the food availability due to redistribution of species, since the areas that are suitable for crop production will either become too dry or will be under water creating a shortage of food worldwide. Animals are migrating to new areas to increase their survival chance, making it difficult for humans to access the same food that they once had before the migration. Fishes are the best example of species shift, due to climate change, the water temperature is rising causing the fishes to travel deep down into the ocean where it is cooler. As the fish travels further down, harvesting fish will become expensive causing economic crises eventually affecting the human well-being. On the other hand, the changing climate change is also posing new health risks for humans, such as some countries are now suffering from malaria, a disease transmitted by mosquitoes. Due to a rise in worldwide temperature, mosquitoes can travel to numerous suitable places. An indirect effect of climate change will be the stress that the plants are facing now. Because of lack of trees on land, the carbon dioxide rate in the atmosphere is increasing which is raising the temperature and melting the tundra region, thus raising the water level. Because of climate change, humans are encountering various problems that can only be solved if the governments take initiative and find a solution for the situation. If world leaders wait any longer, a major catastrophic situation can occur that will dramatically affect human

Some problems with the global food system are its limited Food Access and its food waste. The inability to access sufficient amounts of food is an issue that happens to populations around the globe. Worldwide, about 795 million people suffer from chronic undernourishment, and about fifteen percent of households in the U.S. lack food to some degree. More than 29 million Americans live in places where they do not have a supermarket within a mile of their home. On top of the absence of these markets, limited mobility, economic barriers, and a lack of fresh food options prevent certain low-income communities from obtaining healthy and affordable food. This problem has only been exacerbated by the farm policy incentives that drive an excess production of sweets, fats, and meats, and producers choosing to cut costs through extensive food processing and use of high fructose corn syrup and hydrogenated soy oil to increase

There is no doubt that climate is a considerable element of agricultural production. However, along with climate change, extreme weather has tended to be more frequent and more intense, which has affected farming destructively. As a result, the drought that occurred in sub-Saharan Africa has become continual and long duration, which resulted in poor harvests. In addition, climate change restricted weather risk management. Similarly, long-time climate change is threatening agricultural development in Australia and has reduced agricultural production capacity and challenged traditional farming and irrigation measures. Interestingly, in most rural areas of Australia, farmers acknowledged “a changing climate”, rather than “climate change”.

Food security is historically defined as the overall regional, national as well as global food supply and shortfalls in supply as associated to requirements (Foster, 1992). The same author contended that, even though, the increased observation of differences in the sufficiency of food intake by certain groups despite overall adequacy of supply, the term has been applied recently at a local, household, or individual level and it has been widened beyond notions of food supply to include elements of access (Sen, 1981), vulnerability (Watts and Bohle, 1993), and sustainability (Chambers, 1989). Different organizations, scholars and institutions define food security differently. However, basic concept remains the same.

The United Nations predicts that the population will go up by at least two billion people by the year 2050. Eighty percent of this new population will be in sub-Saharan Africa and in South and Southeast Asia. These are the areas where climate change will be the most felt. Intergovernmental Panel on Climate Change states that the world’s food supply is in trouble because there has been crop yield drop for corn, wheat, and rice. There are also some places the crops have stopped growing altogether. Climate change’s biggest threat could be on the world’s food supply. Something must happen should to help this issue at hand. This is where the debate of modern technology, such as genetically modified crop, should be used to help the oncoming food dilemma.

Along with the devastation that will follow the increase in natural disasters, global warming will soon prove to be a burden on our agricultural market as well. According to the Environmental Protection Agency (EPA), the “changing climate could cause soils to become drier and drier, and crop failures could become more widespread.” What burdens will this place on the global economy? It will affect the poorest countries first, mostly due to the fact that the majority of these “poor” countries have a high dependency on agriculture as a means of living and trade. Another affect on our agriculture will be the disruption in our food supply according to author and Boston Globe editor Ross Gelbspan, “global warming could result in insect

The four most important global crops are maize, wheat, rice, and soybeans a new analysis found, but the change in weather because of global warming has a large effect on food production globally (Limb, 2015). Global warming has also caused a rise in sea level, and droughts also pose a problem for trying to feed the whole population, and raises the prices of staple foods (Puckett, 2011). In Canada we have the high, middle, and low class, with lower class people struggling to make ends meet, and put meals on the table. The rise in food prices makes this harder, not only for those in other countries but for people in our own country, potentially right next door. Individual grain prices were shown to have doubled in no time at all during past production problems (Limb, 2015). Food shortage is a world wide problem, it does not just affect those in under developed countries, it effects those close to us. If we are not going to become more mindful about our decisions, then the decline in staple foods, and the incline in food prices will continue to get worse. This is the fault of global failure, and will continue to be unless the entire world does something about it.

The current global food system is highly fuel- and transport-dependent. Fuels will almost certainly become less affordable in the near and medium term, making the current, highly fuel-dependent agricultural production system less secure and food less affordable. It is therefore necessary to promote food self-sufficiency and reduce the need for fuel inputs to the food system at all levels.

The human need for food is one of the inherent and physiological needs; it is the most important factor for the survival and life. Food is an essential need, and human is forced to obtain food to quench the hunger. Proper nutrition and balanced is good for growth and leads to better health and longer lifespan. Initially, eating was only to crunch hunger, and feeling of hunger forced the human to consume everything that was available regardless of the quality and nutrition. Later, humans learned how to use the land and nature to provide their variety of food to consume. The urbanization and social life have caused many changes in the way human consume nutritional food. Today in regard to the growth of population and their need for food producing is one of the human concerns in contemporary society. As it is forecasted that by 2050 the world population will be 9.6 billion people. Due to the growing population and changing diets, the world will need to produce 69% more food (Ranganathan, 2013). Now, this question comes in mind that how this amount of quality food should be produced for the population. Although, we have advanced technology, several factors such as climate change and soil quality of the lane will restrict the production of food around the world. Thus, these factors will give negative impact and restriction in the different region. We will face a difficult challenge of overtime to meet with these four principles: access,

Climate change has also had a negative impact on the aquatic life. For instance, fish normally thrive and reproduce in cool waters. Global warming results in a very high rise in temperatures; however, the effect is not normally felt since water covers more than two-thirds of the earth’s surface and therefore absorbs much of the rise in temperature. The Ocean temperatures have therefore risen to very high levels that are not conducive for reproduction of fish; this has resulted in a significant reduction in the population of fish species with others becoming extinct while others try to migrate to regions where ocean temperatures are lower (Harley et al., 2006). The reduction in the population of fish has resulted in a great imbalance in the ecosystem and food chain as other ocean creatures that would feed on fish have to look for other predators or also die.

Rosenzweig and Parry (1994) conducted a study that employed this approach. They examined climate change effects on worldwide grain production and the distribution of these effects between developed and developing countries up to 2060. The scenario that was used predicted that worldwide grain production could decrease between 1% and 8% and prices would go up between 24% and 145%. The inclusion of farmer adaptations at the farm level helped to mitigate these impacts to the extent that the projected change in world grain production varied between -2.5% to 1%, and that of global prices fluctuated between -5% to
