Consequences Of Climate Change On Food Systems

People’s food choices are affecting climate change in many different ways.This happens because there is a lot of people who want selective foods and want it on demand without wait.This affects climate change because it makes the food industry do whatever they can to distribute and process the foods even if that means destroying the environment.

Some of that is deforestation, but the use of fossil-based fertilizers and the burning of biomass are the other two major drivers (Climate Institute). On the other side of the spectrum, as the Earth warms, changes that can be expected that relate to agriculture include a shift in agriculture zones away from the equator, a short-term boost in agricultural productivity through carbon dioxide pumping into the atmosphere, changes in rainfall, and changes in production patterns (Climate Institute). This will include some increased productivity, but it will also mean greater food insecurity, shifting land politics, and a scramble to adjust to new production patterns. Any improvements in productivity will be isolated and short-term. Shifts in where foods can be grown will reward the wealthy and punish – often fatally – the poor farmer who will have the seeds that have been married to the particular soil in which they are grown for centuries and millennia. Food crises will lead to food riots worldwide – which have already

Changes in climate have affected the growth of crops. Particularly climate change has increased the amount precipitation fall in North Dakota.

Shifts in temperature and precipitation will be a shock to fragile ecosystems which depend on specific climatic conditions. Many species will be unable to adapt as fast as their environment changes and face sharply reduced numbers or extinction. Scientists estimate that a warming of just 2 degree will put as many as 30% of the world's species at risk of extinction. Plants and animals aren’t the only ones feeling the pressure of changing ecosystems. Many regions will face severe water shortages in a warmer world, creating the potential for conflict. It is believed that the genocide in Sudan’s Darfur region is at least in part a response to water shortages resulting from global warming.

The practice of Drought Tolerant Maize showed excellent consequences under reduced rainfall and warm climate. Moreover, climate information and early warning system were applied in sub-Saharan Africa. They aimed to provide evidences of risk of significant changes in climate ahead and to tack action that can decrease possible risks. In contrast, because of insufficient and incomplete understanding of the impact of climate change on the agriculture, Australia introduced climate change adaptations, which covers obtaining knowledge about how the communities confront the climate change in the

This is a global issue, however the greatest impact would be on Canada, where we are technically advanced in farming. There was a study that showed the relationship between weather related disasters and crop yields from over the globe. The authors of the study outlines how the world’s food supply is vulnerable because of climate change. This creates a strain on the world as there needs to be food grown that would supply the growing population. Navin Ramankutty (the senior author on the study and a professor of global food security and sustainability) states, “The food system is already stressed in many ways.” He also says that with climate change, we are adding more stress on it. Navin and his colleagues at UBC and McGill University took information from a database that had 2 800 weather disasters in 177 countries from 1964 to 2007. The results that they got indicated the impacts on food production from heat waves, and droughts. The study found that recent droughts impact on food production increased by 7-per-cent compared to the droughts from the decades past. This was the effects of climate change. Dr. Ramankutty’s study warns the world food

The Impact that agriculture has on climate change is one of the largest in the world. Climate effects temperature and water availability, weather extremes and flooding and changing CO2 levels in the atmosphere. All of this impacts a shift in crop production patterns across agro ecological zones.

Today’s world is facing many challenges given the growing concerns and current repercussions of environmental climate change and demands of a growing global population. Not only is climate change effecting the worlds ecosystems, human health and fresh water resources, it is drastically effecting the worlds agriculture. Unpredictable weather such, as rising temperatures, colder temperatures, excessive flooding, and droughts are just a few of the increasing weather instabilities, which are challenging and threatening today’s agriculture growth and production. As such, crop yields continue to decline and present a risk to future food security. As a world, we are facing an adaptation deficit leaving us very vulnerable and thus, we must seek to

Due to the immense anthropogenic release of green house carbon emissions into the atmosphere, there has been and will be major detrimental effects on human resources and the ecosystem. For example, by the middle of the 21stcentury, River runoff will increase by 40% in northern latitudes and also in a few tropical areas, while in dry regions it will decrease by 30%. Some of these tropical areas have already reported and are experiencing water droughts that will only get worse (Gillman 2008). In addition, if temperatures continue to increase to 1.8-5.4 degrees, food productivity and resources will be affected. When the temperatures reach the lower latitudes of what is predicted, there will be a slight increase in food productivity for a little while. However, when the temperatures reach the higher end of the latitudes, food productivity will

Weather can take a huge toll on crop and cattle. It can make them stress out. Which can affect the way the crops turn out and cattle growth or milking. Water levels, rainfall amount, hay or grain prices, and prices of livestock is major key. As a producer weather can make huge impact on my plans both long term and short term.

"We call them dumb animals, and so they are, for they cannot tell us how they feel, but they do not suffer less because they have no words” (Anna Sewell). There is undeniable evidence that animals are being affected by climate change. Even though the effects are difficult to measure, there are many different ways animals are being affected. With the loss of predator and prey species it affects the life cycles in the food chain. The earth’s climate change causes habitats such as snow, ice, or forest areas to alter, resulting in loss of habitat and food accessibility as well as causing extinction.

Drought is another factor of climate change that causes severe damages to agriculture and livestock. The effects of drought on agricultural production and livestock holding can be a detrimental issue and result in quality dissatisfaction of products. The agricultural industry can be affected by drought both economically and environmentally. The economical effects of drought on crops and animals can lead to the loss of money and time. When droughts occur farmers lose money because they will have to spend more money earned from their

Climate change otherwise known as global warming has been an ongoing issue for decades. Beginning in the 19th century, climate change has increasingly affected Earth and its atmosphere. Rising levels of carbon dioxide are warming the Earth’s atmosphere, causing rising sea-levels, melting snow and ice, extreme fires and droughts, and intense rainfall and floods. Climate change has and will continue to affect food production, availability of water, and can add to many health risks in humans and animals. In fact, in an article by Justin Gillis titled, “Scientists Warn of Perilous Climate Shift Within Decades, Not Centuries” he focuses on a paper written by a former NASA climate scientist, James E. Hansen, explaining the effects of climate change on Earth today. Although many believe Hansen’s theories in the paper are quite far-fetched, the author mentions, “Despite any reservations they might have about the new paper, virtually all climate scientists agree with Dr. Hansen’s group that society is not moving fast enough to reduce emissions of greenhouse gases, posing grave risks” (Gillis). Gillis validates the fact that climate change has been rapidly expanding throughout Earth and society has not been able to reduce it fast enough. Many negative risks are being posed and will continue to mount if the issue of climate change is not taken seriously. Although climate change negatively affects nearly all aspects of Earth, it poses a big

Firstly, climate change has a big impact with world hunger. Climate change may affect food systems in several ways ranging from direct effects on crop production (e.g. changes in rainfall leading to drought or flooding, or warmer or cooler temperatures leading to changes in the length of growing season), to changes in markets, food prices and supply chain infrastructure (Gregory, Ingram & Brklacich, 2005, p.2139). It can trigger a natural disaster like drought and flood, which can have an extreme effect with the problems in the sources of food. In one hand, drought is a common scenario in farm lands in which

These climate change can have wide ranging, often unanticipated, effects on the environment and on socio- economic and development related sectors, including agriculture food security,
