Adaptation to climate change is defined as the range of actions taken in response to changes in local and regional climatic conditions (Smit et al., 2000). Climate change adaptation simply means reducing the vulnerability of people’s lives and livelihoods to risk posed by climate change. Agriculture adaptation measures can be categorised into policy level interventions, technology development and farm level management practices.
The government of Sri Lanka realising the importance of climate change adaptation has taken number of initiatives at policy level to address the concerns of climate change and among the initiatives; the most important is the recently formulated national climate change adaptation strategy. The national climate change adaptation strategy is structured into five strategic thrust areas of which the third thrust area is focused on minimizing climate change impacts on food security (NCCAS, 2010). Sri Lanka ratified UNFCC in 1993 and the Kyoto Protocol in 2002, thereby affirming commitments in the United Nations Framework Convention on Climate Change. Sri Lanka...
The general idea of the order listed in NDAA is the adaptation, defined as the adjusting to the effects of climate change in our environment, instead of addressing the very important topic of mitigation, which is the reduction of harmful greenhouse gases and other pollutants to slow the effects of climate change (Source 6).There are several problems that arise with this exclusion because this is a major threat to the survival
It is obvious that the community has been the source of some of the most creative and successful practices that have been proven to weather the problems of climate change. Henry Hurage, who is a farmer from Kenya, convinced 300 other farmers to follow practices he had learned in England. The result was that this particular group of farmers were the ones who fared the best when a drought had hit the area. They also became more self-reliant (McKibben, 2011). This is only one of the many examples of "experimental" innovations that communities all over the globe are adopting. However, whil...
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
The clock is ticking! Global Co2 emissions have increased exponentially since the industrialization of today’s developed world. Emissions have now passed the absorptive capacity of the earth and are accumulating in the earth’s atmosphere, warming the surface of the earth and inducing localized climatic changes. Climate change is often a localized issue. Many regions of the world will continue to become hotter, while others may experience highly variable weather patterns. Climate change poses a serious threat to ecosystems, economic sectors, and human welfare. Although almost entirely caused by the developed world, climate change will disproportionally affect the world’s poor.
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
“We are already seeing major impacts of climate change on agriculture; droughts leading to crop loss, salinization of soils, longer growing seasons leading to new and pest pressures, and erratic weather shifting harvesting seasons.”(Rosenzweig 1). Scientists all over the world like Rosenzweig believe regulations can reverse some of the damage already done to the earth. One negative effect from climate change is the rapid melting polar caps and glaciers, “As the climate warms, glaciers are melting. Yet millions of people depend on the planet’s 190,000 glaciers to supply water in dry seasons. Arctic sea ice is melting rapidly, a process that further speeds up climate change.”(Greenpeace 1). The melting ice caps also contribute to the rising sea level and could cause serious damage, enforcing regulations could slow down global warming therefore, the glacier problem could reduced by protecting and preserving

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
Climate Change and Sustainable Development This research paper is about climate change with the concept of sustainable development, meaning that it will approach the climate change problem in an economical way and try to solve it with the new growth theory. New growth theory argues that innovations, population growth, new technology, and creative destruction are connected to each other and that these connections will solve the climate change problem. The exponential technology growth, improved international private rights and improved use of human capital are some of those key terms that the theory is all about. The most important thing towards the solution is human capital.
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.
Given the importance of climate change impacts on 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 of 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.
Evidently there have been significant impacts on different sectors of the Philippines and its citizens. Unfortunately these impacts will only increase if action is not taken soon. Therefore, now more than ever, it is crucial to develop sensible strategies on the mitigation of climate change in the Philippines.
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...
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
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...
