Climate change is an inevitable phenomenon that is being experienced globally in various forms such as temperature rise. Sea level rise, droughts, floods, hurricanes, landslides, etc. According to the forth assessment report of the IPCC project even with immediate implementation of mitigation strategies global climate change will continue for decades. Climate change is inflicting serious consequences on human wellbeing and will continue to inflict damages in the future. It is estimated that mean global temperature will rise by 1.8 ºC - 4.0 ºC by end of the 21st century (Izaurraade, 2009). 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 end of the 21st century will exceed the most extreme temperature 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 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).

...local agriculture and food security, this paper attempts to give an overview of observed and projected climate change in Sri Lanka, its impact on the agriculture sector and climate change adaptation strategies through reviewing recent literature on climate change. To develop appropriate strategies and institutional responses to climate change targeting smallholder farmers it is necessary to have a good understanding about the local farming environment in terms of farmer perception about climate change, key issues faced by farmers in overcoming climate adversities, local knowledge and strengths on climate change adaptation. There is a dearth of such research studies undertaken in Sri Lanka therefore; this paper presents a case study undertaken on a farming community in the intermediate zone to demonstrate how farmers perceive and respond to climate adversities.
Climate change is a global problem because this Earth is home to many, and the artificial sources causing climate changes have been caused by many people over the course of many years. The changes can be seen on a day-to-day level through the rise in average surface temperatures (Figure 3A, Figure 3B). Climate change will change landscapes and increase sea levels due to the melting of ice and changes in water runoff; put wildlife at risk of extinction; increase the risk of drought, wildfires, and floods; lead to increased likelihood of storm damage due to stronger storms and storms occurring in previously not at risk regions; and cause a development in more heat related illness (“Climate Change: Threats and Impacts”). The repercussions of climate change will affect every nation, and major changes will have to be made for everything from farming to fashion. With every way of life at risk and every person and nation making contributions, whether extreme or minute, climate change is undoubtedly a global
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.
Climate change is currently generally regarded as a major global issue that is especially acute in developing countries. This study focuses on the impacts of climate change and variability on smallholder farmers, their vulnerability and coping strategies on a micro-scale in a developing country.
While it is evident that climate change will greatly affect temperature and precipitation over the coming decades, these changes in patterns will also have numerous effects on agriculture as extreme weather events can lead to disruptions within the food system. Climate change will make it more difficult to produce enough food for the world’s increasing population due to the alterations of planting and harvesting times, as well as the accessibility and quality of water. The USDA Technical Report found that increases in temperature, coupled with more variable precipitation, would reduce productivity of crops, with these effects outweighing any benefits of increasing CO2 (Murray 4). Along with the reduction of crop productivity will be an increase
The causes of climate change are also known to them that though it is not only the human action playing role but it is the main cause of climate change. The effects of climate change does include harm and loss of environment and organisms but it also has impact on the human health. Semenza (2014) displays an assessment report which states that throughout the 21st century, the rapidly occurring climate change will lead to increase in number of humans with ill health in many regions mainly in those of developing countries where citizens face low income. Semenza (2014) also mentions how there are physiological limits to intense heat exposure and the global climate change will turn some parts of the world which are currently highly populated into uninhabitable even if the global temperature rises by 7 degrees Celsius. Johnson (2014) states how El-Niño-related hydroclimate variability will lead to being intensified under global warming mainly in areas as southern Asia which are already stressed by different droughts, floods, and crop yields. Dettinger, Udall, and Georgakakos (2015) mentions how climate change puts risk and threat on water resources in the western United States to an extent that no other part of the country matches it. Dettinger, Udall, and Georgakakos (2015) also states how recent research and studies strictly point a limited number
Leading to our planets slow demise, global climate change is an important issue that has sparked fascinating research on its causes, as well as its future effects. There has been significant change in weather patterns and climate over the past century. Sea levels are rising, ice caps are shrinking, and extreme unexpected disasters are occurring all over the world at an alarming rate. This means devastating outcomes for the future of planet earth, along with all of earth’s inhabitants. Earth is home to billions of people, as well as countless species. The despondent truth is that humanity is to blame for global climate change.
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.
Global temperatures have noticeably been rising since the mid 1800’s.The average temperature has increased by 0.6 ± 0.2°C since 1860 according to (John Sweeney, 2003)with accelerated warming apparent in the latter decades of the 20th century. The legitimacy of global warming had long been debated, however in a report by (IPCC, 2007) it states that warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global average sea level. Simulations on models such as EC-Earth provide us with predictions for future climate change. Depending on levels of emissions an increase of 1 to 5.5 degrees celsius is expected in average global temperatures by 2100.
Over 650 million Indians depend on climate-sensitive sectors like agriculture, forestry and fishery for their livelihoods. The adverse impacts of water availability due to change in rainfall, increased flooding in certain areas and recession of glaciers combined with increased water demand due to demographic development and climate change could threaten food security, destabilize the natural ecosystems including species that sustain the livelihood of rural households and impact the coastal system due to sea level rise and increased extreme weather events (Garg et al. 2007).
Climate change effects the food systems through crop production. Changes to rainfall, which can either lead to drought or flooding, will have impacts on production (food availability). This will have further effects on markets, as food prices will change (food access).(Gregory et. al. 2005). However, there are some doubts to wether climate change is even occurring.
...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.
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
It’s impossible for poor rural women and their communities to cope with the effects of climate change when both are perpetually in crisis mode. Their capacity to adapt must be strengthened. Compared to men in poor countries, women face additional cultural, social and economic barriers that make them more vulnerable to climate change. They have limited access to productive assets such as land, credit, and extension services, and they continue to lack voice and decision-making power on agriculture policies and programs. As a result, they are in many cases the first casualties of volatile climate conditions, falling into food insecurity and malnutrition. This reality demands a gender analysis toward climate change mitigation” (Hunger report 22) This being said, our increase in involvement improving women’s rights for education, ability to voice their opinions and breaking cultural norms that restrict them will result in less stress as well as more food. This will break the cycle of poverty. Educating women agriculturally will benefit them and increase their involvement in growing and cultivating produce, which will lead to them selling what they make and gives in increase in their home’s
