Climate Change Theory

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.

The purpose of this study is to help model one of the world’s most economically important crops, coffee. In this article Brunsell and his colleagues are trying to relate the variations in yield of coffee with microclimatic variations, as well as agricultural practices. In doing so this will help them better understand the impacts that global climate change will have on not only coffee crops but it could also even help them with other crop disturbances that will happen during climate change. This article is an important piece

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.

Agriculture helps the United States economy by contributing more than three hundred billion dollars each year. This number is kept stable by having consistent amount of agriculture farmed or raised each year and it is creating a sustainable food supply. Climate change is capable of destroying this stability and contribution from agriculture. Climate change is a serious problem that is currently happening and is destroying the agriculture’s productivity which has an impact on everyone.

One of the biggest problems in society due to the issue of climate change is the reduction and loss of crops and livestock, which can be

Maddison (2006) affirms that adaptation to climate change impacts requires farmers to understand that the climate has changed before they can identify adaptation measures and implement the appropriate technologies. Mitigation concentrates on reducing the causes of climate change while adaptation focuses on the impacts of climate change (Legesse et al., 2013). Adaptation to climate change impacts has two distinct perspectives, the perception of the potential risks of climate change and the ability to adapt to climate

(2014) built on this research by using the biophysical crop production simulation model APSIM (Agricultural Production Simulator, (Keating et al. 2003) with one of the hottest and driest future climate change scenarios (the CSIROMk3.5 A1FI scenario) to provide information on the impact of climate change on cotton yield and irrigation water requirements for the southern Queensland region. These simulations highlight the complexity of the cotton production system especially the ameliorating effect of CO2 fertilisation on growth that would otherwise be highly compromised with decreased rainfall. The simulations indicate yields increasing by 5.9% to 2030, but then decreasing by 3.6% to 2050.

These days, scientific-technology and agricultural technology have been developed. However, in spite of this advancement, weather and climate change has influence on many facets of agriculture on bad side. It can cause the instability of agricultural supply and demand due to frequent unusual weather, the new disease and insect pest and prevalence of weed grasses. On this wise, climate change in agriculture causes great damage.

field and blue skyClimate change could make it too hot to grow certain crops, and droughts caused by climate change could reduce the amount of water available for irrigation. Climate change is also likely to cause stronger storms and more floods, which can damage crops. Higher temperatures and changing rainfall patterns could help some kinds of weeds and pests to spread to new areas. If the global temperature rises an additional 3.6°F, U.S. corn production is expected to decrease by 10 to 30 percent.

Water Scarcity: Water is essential to the growth of crops, lack of water would drastically lower the amount of agricultural yields. Lake Chad, pictured on the side, is on the border of four countries and is a huge water source. However, over the past 40 years, this lake has been shrunk to 1/20 of its size. Due to Chad being a land-locked country, it is dependent on this lake for water. The disappearance of Lake Chad has decreased food production as many crops are suffering from dehydration. The inevitable future can be predicted, if the drought and overconsumption of water continues to occur, Lake Chad will soon completely disappear leaving four countries high and dry. Technology and

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”.

The data that has been presented will now be broken down and simplified as well analysed as to what it all means for the agriculture business sector. However, there may be additional information included to help support our findings. Presently the agriculture system is already struggling with the increased demand for food and renewable energy. Now with the climate change issues of temperature increases, raised sea levels, the issues of water scarcity, pollution, and soil degradation are also now playing a large factor in today’s struggles. Small differences in weather or more specifically temperature can affect a farmer’s crop more than we realise. Crops with a higher level of average temperature will require more water in order to stay

Climate change is one of the major issues surfacing earth over the past century. The earth’s temperature has increased over the years leading to detrimental effects on the economic and life sources of people, especially that of agricultural production and livestock. The Merriam-Webster online dictionary (2014), defined climate change as a change in global climate patterns apparent from the mid late 20th century. The Intergovernmental Panel on Climate Change, IPCC, (2007) predicts that by 2100 the increase in global average surface temperature may be between 1.8° C and 4.0° C. With increases of 1.5° C to 2.5° C, approximately 20 to 30 percent of plant and animal species are expected to be at risk of extinction. Moreover, the IPCC (2007)

We divided the time domain into three periods, baseline period (1990-2011) and mid future (2046-2065) and far future (2081-2099) periods for climate change scenario analysis in the present study. Moreover, the model requires good quality observed data (1990-2011) to calibrate with NASA (National Aeronautics and Space Administration) data which obtained from the Global Yield Gap Atlas (GYGA, http://www.yieldgap.org). Depending on projection data availability in five regions for an observed period (1990-2011) and two future periods (2046-2065) and 2081-2100) were taken into consideration for future yield simulation of rice. The predicted changes in climate and their impacts need to be assessed relative to the observed period. The observed climate (1990-2011) is significantly different from the climate of the past years, for example, 1961-1990. Similarly, some climate change studies have been used the daily observed weather data as a reference (baseline period) climate (Kumar et al. 2014). Table 1 illustrates the relative change of mean maximum and minimum temperature, total

Climate risks, such as flood, drought, typhoon, and weather variability are inherent in agriculture (Collier, Skees, & Barnett, 2009; Conway & Schipper, 2011; Fuchs, Berkeley, & Wolff, 2010; Lyu & Barré, 2017). Usually, erratic weather expose farmers to substantial production insecurity and serious financial hardship. The frequency and severity of such risks facing farmers may vary by agro-ecological set up, farming technology, and agricultural policy of respective countries. However, erratic weather born drought is the most damaging environmental phenomenon (Kogan, 1997; Thornton, Jones, Owiyo,
