Recommended: An essay about food security and three causes
Food security is the term of the availability at all times to access the basic food that they need (Moir & Morris 2011). Food security is a wicked problem as it is just not a level of difficulty, but it is more about the complexity, interacting evolving in a dynamic social context. There is no right solution, even-though you solved one problem there will be other problems emerge non stop and usually stays in a long term (Camilus 2008). The issues that existed in food security as a wicked problem, including climate change that also causing availability in regarding to agricultural production, particularly in tropical regions such as Thailand.
Firstly, the gradually worsening of the climate change effects causing our world lives such as drought and floods which posing many challenges to farmers and ranchers in the agricultural sector. In Thailand, the suffered from big flood in the past two years and the changed in temperature are likely to cause the habit of ranges of many species to shift and lead to a lessen yield of crops that will decline by 17 percent in 2050 (GLF Committee 201...
The plants we grow for food needs specific resources to thrive, which includes the night temperature and enough water. A changing climate could create a lot of problems. Climate change could make it too hot and also make it too cold to grow crops in some areas of the world and also climate change can cause drought, which is made by the unavailability of water for irrigation. Climate change is likely to cause stronger storms and more floods, which will damage the crops. . Latin America and Southern Asia is seeing it in lethal storms and floods whereas Europeans are experiencing it in melting glaciers, forest fires and disastrous heat waves (Pearce, 2006). Deforestation is another anthropogenic factor that is causing climate change because of the need for fossil fuel, agricultural lands are being used. Forests are being burnt down by humans on a daily basis. As agricultural lands becomes less in need of growing population, people extend their space by cutting and clearing forest. The land beneath the forest sometimes tends to be unproductive and lacks the natural chemicals for a growing. The plantation will serve as a source of food for a few years after then the land becomes useless because of its infertility, it nutrients get depleted and used up. Deforestation results in numerous problems such as destruction of our natural resources, ecosystem, wildlife,
As explained by Rosenzwig, “We are already seeing major impacts of climate change on agriculture: droughts leading to crop loss and salinization of soils, flooding causing waterlogged soils, longer growing seasons leading to new and more pest pressures, and erratic weather shifting harvesting seasons” (854). We know agriculture and fisheries are highly dependent on specific climatic condition. Increases in temperature and carbon dioxide can be beneficial for some crops in some places. But to realize these benefits, nutrient levels, soil moisture, water availability, and other conditions must also be met. Changes in the frequency and severity of droughts and floods have posed challenges for farmers and ranchers. Meanwhile, warmer water temperatures are likely to cause the habitat ranges of many fish and shellfish species to shift, which could disrupt ecosystems. Overall, this climate change has made it more difficult to grow crops, raise animals, and catch fish in the same ways and same places as we have done in the
Traditional agriculture requires massive forest and grassland removal to obtain land necessary to farm on. Deforestation and overgrazing has caused erosion flooding, and enabled the expansion of deserts. But with drainage systems, leveling, and irrigation provided by the Green Rev, all this terra deforming will unlikely happen again. We can retain clean air and lessen the global warming effect caused by deforestation.Many people argue that a revamp in agriculture will be way too expensive and unrealistic especially for those poor farmers in third world countries. However many times, they exaggerate the price.
One of the wicked problems or super wicked problems that human faced recently is climate change, this issues is no longer environmental issue but it is shifting to broader aspects such as political, socio-economic and policies frames.
There are many problems confronting our global food system. One of them is that the food is not distributed fairly or evenly in the world. According “The Last Bite Is The World’s Food System Collapsing?” by Bee Wilson, “we are producing more food—more grain, more meat, more fruits and vegetables—than ever before, more cheaply than ever before” (Wilson, 2008). Here we are, producing more and more affordable food. However, the World Bank recently announced that thirty-three countries are still famine and hungers as the food price are climbing. Wilson stated, “despite the current food crisis, last year’s worldwide grain harvest was colossal, five per cent above the previous year’s” (Wilson, 2008). This statement support that the food is not distributed evenly. The food production actually increased but people are still in hunger and malnutrition. If the food were evenly distributed, this famine problem would’ve been not a problem. Wilson added, “the food economy has created a system in w...
Food insecurity defined, is ‘the state of being without reliable access to a sufficient quantity of affordable, nutritious food’ (Oxforddictionaries.com, 2014). This in turn leads to hunger, which can have three possible meanings; 1) ‘the uneasy or painful sensation caused by want of food; craving appetite, also the exhausted condition caused by want of food’, 2) ‘the want or scarcity of food in a country’, and 3) ‘a strong desire or craving’ (Worldhunger.org, 2014). Food insecurity also leads to malnutrition, with 870 million people in the world or one in eight, suffering from chronic undernourishment (Fao.org, 2014). From this alarmingly high figure, 852 million of these people live in developing countries, making it evident that majority of strategies used to solve this problem should be directed at them (Fao.org, 2014). The world produces enough food to feed everyone, with an estimated amount of 2,720 Kcal per person a day (Worldhunger.org, 2014). The only problem is distri...
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 scale 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. Historical temperature yield relationship indicates that at the global scale warming from 1981-2002 very likely offset some of the yield gains from technology advances, rising CO2 and other non climatic factors (Lobell and Field, 2007).
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...
One of the most complex issues in the world today concerns human population. The number of people living off the earth’s resources and stressing its ecosystem has doubled in just forty years. In 1960 there were 3 billion of us; today there are 6 billion. We have no idea what maximum number of people the earth will support. Therefore, the very first question that comes into people’s mind is that are there enough food for all of us in the future? There is no answer for that. Food shortage has become a serious problem among many countries around the world. There are many different reasons why people are starving all over the world. The lack of economic justice and water shortages are just merely two examples out of them all.
Since 1960s both minimum and maximum temperatures have exhibited a rising trend; with minimum increasing by a range of 0.7-2.0 degrees Celsius and maximum by 0.2-1.3 degree Celsius varying by region and season. Notable also is variability of rainfall patterns such as below normal rainfall in the long rains season and more during the short rainfall season, some regions have recorded more intense rainfall and downpours that have resulted to floods and infrastructural impairments. Extinction or near extinction of flora and fauna, changes in flowering and maturity patterns in crops are all attributable to climate change. These changes have had and are expected to have far reaching impacts on the economic sectors of the economy. Some of the expected sectoral impacts are discussed

There are those that believe our planet has reached its maximum capacity to sustain humanity and we need to reduce our population to rectify it. It is also said that our planet is well capable of providing both the nutrition and caloric needs for humanity, both now and into the future as well. Regardless of where one’s opinion of the facts fall between these two arguments, global food security is not where it should be. Uneven development could be argued to be a cause of this. But it is not the only issue affecting the planet.

It could, however, be argued that with the exponential growth of the human population intensive agriculture in the long-term reduces the rate at which new areas of land have to be cultivated, effectively reducing the need for extensification and environmental damage.

Global warming is one of the main causes, which leads to the lack of water and drought. A drought-like condition exists in most of India’s part. Government of India states that 68% of the country is disposed to the drought, which (consequences are) leads to massive migration of people to more favorable places, famine, conflicts among inhabitants. India is known in the world as one of the biggest producers of water-intensive crops such as rice, sugarcane and wheat. According to a survey done by Grail Research, approximately 82% of total water is used for agricultural consumption and 90% of it is employed for irrigation of rice, wheat and sugarcane (Grail Research, LLC, 2009). There are several solutions which could lead to the decr...
