In this essay, the effects of climate change on agriculture and how to manage it shall be discussed. Climate change has and will greatly affect agriculture. As time progresses, the effects of climate change will worsen and become detrimental. Mendelsohn and Dinar (2009:1) state,” if future climate scenarios lead to a widespread reduction in food supply, there could be massive problems with hunger and starvation”. Climate change is a change in global climate patterns which is mainly caused by the increased levels of atmospheric carbon dioxide produced by fossil fuels. The writer chose this topic because climate change is a global problem that will pose a threat to people’s lives around the world and must be dealt with sooner than later. One of the impacts of climate change is that as the temperatures in cooler parts of the world change and become warmer, this will allow that place to be more habitable to other different types of food crops, thus expanding the area in which these crops can be grown. For example, less frequent freezes will allow crops like citrus to be planted and gro...
For years to come there will always be a speculation on whether the climate change has really taken place or not. Many believe that large companies launched this topic in order to benefit from it in profit, as there are also those who are convinced that this are consequences that have emerged from human mistakes in understanding the environment. As humans are struggling to trust one another whether it is just a big conspiracy or not or environment changing itself, we are slowly starting to feel the effects of climate change. Because of the gasses (CO2) that are in the air, atmosphere is getting warmer, thereby triggering the Greenhouse effect. Almost 70% of emitted gasses in air are CO2, which leads us to believe that this is the main cause of Global Warming. Since it is billions and billions of metric tons per year that are being released in air, many scientists conclude that temperature will most likely be more higher in twenty years from now, than it was in near past.
Climate change has become of the world’s major issue today. The earth’s climate is always changing in a very fast and also in different ways. Climate changes affect our lives psychologically, emotional and also physically. Climate change is defined as a long term change in the earth’s climate, especially a change due to the increase in the average atmospheric temperatures. Due to this change in temperature, a lot of changes has occurred in our environment, these changes include rising sea levels, flooding, melting of polar ice caps, hotter days, colder nights and heat waves. These climate changes plays an important role in shaping our natural ecosystem, our human economics and also the most important, it affects the human race. For
One of the biggest problems facing the world today is global warming. The main reason behind it is the production of carbon dioxide from our cars, factories, power plants and other greenhouse gases, which is having a heating effect on the atmosphere, and this affects our ocean weather and agriculture, thereby dangerous to human life. “In Climate Crisis at the End of Our Fork “Anna Lappe gives her views on how global warming can lead to many problems, what are its probable causes and potential solutions to it. Whereas in “Research and Development on Climate Change and Greenhouse Gases in Support of Climate Smart Livestock Production and a Vibrant Industry” Scholtz discusses the impact of global warming and continued, uncontrolled release of greenhouse gases on the livestock industry and consequently food security as well as
The effects of climate are felt throughout the world, all living things are affected with it. The effects of climate change are affecting directly the human life. It has been noticed that around the globe, seasons are shifting, temperatures are climbing and sea levels are rising. The world compares to century ago, it has changed drastically and it is becoming worse with climate change. Climate change will rapidly alter the lands and waters which we all depends upon for survival which will leave our children thus the future generation with a different world. In the time to come if not much is done for the case of climate change, There will be shortage of food and drinks, many new illnesses and diseases and some part of the world will become in appropriate for living things to live due to natural disaster. It can be that with the rapid Global warming and climate change, one-fourth of Earth’s species could be headed for extinction by the year 2050.
With the rapid growth of our global population pouring into the next millennium, we will witness an ever-growing hunger rate around the world. That is unless we call for a revolution on the global scale. The Green Revolution which already sprouted in the early part of the century only need to add a bit more momentum and we will see a bright future for the human race, a future without hunger and starvation ¡V hopefully.It is becoming increasingly difficult for the planet to support its overwhelming population. And since the amount of arable land available is becoming scarce, we must seek ways to dramatically improve crop yields of existing cropland.
Although, the sun is great for crops a little too much of it and not enough rain can damage a farmer’s crops in a blink of an eye. In order to keep their crops developing and hydrated crop farmers invest in a pricey irrigation system. An irrigation system protects crops from becoming dehydrated from little rain and help them grow. However, an irrigation system can damage crops by drowning them with too much water if it rains the next day after the farmers use it. Therefore, farmers have to know when the perfect time to use the irrigation system on their crops. Furthermore, Summer affects produce farmers by drying out their product and the soil. In order to increase the yield of their produce in the Summer, they put fertilizer in the soil to help their crops grow. Additionally, many produce farmers start to plant winter crops in order for them to be ready to harvest in the coming Spring time.Similarly, Summer has affected animal farmers as well. Animal farmers have to produce an air conditioning system for their livestock to keep them cool in the harsh, hot temperatures of Summer. Summer affects livestock farmers by the increase in the use of water and electricity to keep their animals cool and hydrated. In addition, the livestock farmers cost of feed will increase to help their animals gain weight for the harsh Winter
http://www.pacificecologist.org/archive/14/food-security-climate-change.pdf Dr. Jon Barnett evaluates and discusses the impact of climate change and how it will increase threats to food security, through its impacts on food production, health, infrastructure, the ability of countries to import food, and the ability of households to purchase food. Barnett debates the impact of international business and trade and how it has caused an influx of cheap food that have little nutritious value. He suggests more immediate reactions to climate change because the traditional ways of life found on the South Pacific islands are at risk Morrell W, & Scialabba El-Hage, N. (2009).

Wheat likes to grow in 70 to 75 F temperatures. It needs lots of sunshine, low humidity and 12 to 15 inches of rain. “Moderate warming and more carbon dioxide in the atmosphere may help some plants to grow faster. However, more severe warming, floods, and drought may reduce yields” (Climate Impacts on Agriculture and Food Supply). This means crops can produce more wheat when there are good temperatures and carbon dioxide. Less wheat is produced when there is bad weather such as floods or very little rain. According to the website, “Dealing with drought could become a challenge in areas where rising summer temperatures cause soils to become drier.” (Climate Impacts on Agriculture and Food Supply). Dry soil destroys wheat crops. In summary, temperatures and water are very important to soil because it affects how much wheat is produced. So, without good temperatures, rain, and soil there wouldn’t be enough wheat to produce
...cause and effect relationship of climate and human activity, and climate and human need, the ability to redesign the way we produce and cultivate food staples can be created. With this ability the longevity of agricultural systems can influence a decrease in food prices, in turn increasing the number of food secure populations.
A lot of factors affect changing scenario of crop production, for example, lower agricultural productivity of certain crops, costly and inadequate supply of inputs, reduced crop varieties, low level of production diversification, high level of land fragmentation, reduced indigenous and communal farming practices
However one may argue, that will be more beneficial for the Philippines to strengthen its BPO industries rather its agricultural industry because of the possible threats of global warming and climate change. However, this could be refuted with the development in varieties of crops that will endure changes in climate, making farming more favorable.
Recently, there was a news about multiple farmers’ suicide in Southern part of India as a result of annual crop failure. In areas like southern India, these incidences are quite relevant as the climate there is always dry and arid. But it gets shocking when crops deteriorates some other developed nations. The rate of crop failure is increasing and is becoming more relevant everywhere. Agriculture failure is affecting almost all agrarian areas. No other factors contribute more to this catastrophe than the climate change, also known as global warming. The elevation in the Earth’s average temperature as a result of burning fossil fuels and other natural or human activities produces carbon dioxide, which acts like a heat trapping gas and affects the earth in various ways. Among the most affected areas of climate change, agricultural sector is facing some serious threats through factors like increasing temperature, extreme precipitation, and droughts, etc. Today, agriculture comprise most of the world food supply, but the rising global warming is rapidly limiting the production around the globe.
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) purported that climate change has severe consequences for food security in developing countries. There are numerous factors that are solely responsible for this change which are both natural and man-made. Climate change has led to a decrease in quality and quantity of plant produce and livestock because of heat stress, drought and an increase in plant and animal diseases.
A new global climate model predicts that in the coming decade, the surface air temperature is likely to exceed existing records (Smith et al., 2007). Growing season temperatures in the tropics and subtropics by the end of the 21st century will exceed the most extreme temperatures recorded in the history (Battistic and Rosamond, 2009). Agriculture is considered to be one of the most vulnerable sectors to climate change. Although at present, the overall impact of climate change on global agricultural productivity is not reliably estimated (Gornall et al., 2010). Many studies show serious implications on agricultural productivity, for instance IFPRI(2009) projects that in South Asia by 2050 climate change will reduce production of rice, wheat and maize by 14%, 44% to 49% and 9%-19% respectively relative to no climate change situation.
Climate change is currently affecting agriculture because it is causing prolonged droughts, violent flooding, sea level to rise, and also health related issues. Droughts and flooding utterly affect agriculture because it damages cultivation since the amount of water applied to crops and farming is fundamental to the...
