The impact of climate change:
Climate change is a global phenomenon, and its impacts have been witnessed in different areas in the world. The change in climate can be monitored through a number of aspects:
1- An increase in the temperature mean: In 2010, the world witnessed the warmest year since 1800, 19 countries have set new rise in the national temperature, among these 19 countries, five were Arab countries. The temperature in Kuwait during this year reached 52.6°C, then rose again to reach 53.5°C in 2011. Morocco and Mauritania are expecting a temperature increase by 5°C by the end of this century. This high rates in temperature can affect crops that need low temperature such as olives. Furthermore, high temperature rates can have a negative

In Syria, the rainfall is expected to decline by more than 20% over the next 50-70 years. In addition, rainfall in Morocco has declined by about 40% in spring since 1960, and Djibouti is experiencing less rainfall by 80% since 2007 . Given a fact that 74.5% of temporary crops areas, and about 59.6% of permanent crops areas in Arab countries are rainfed (table ), any decrease in the amount of rainfall will definitely affect the agricultural production in the region. On the other hand, the severe increase in the level of rainfall can cause floods, and leads to catastrophic consequences.
5- Rise in the sea level: Rise in the sea level is a globally expected phenomenon. Levels of oceans and seas are globally monitored through satellites. Since 1870 to 2013, total rise in the sea level is approximately 18 centimetres. Meanwhile, coastal areas in Arab countries are threatened by the rise in the sea level, this includes Alexandria in Egypt. Studies have expected rise in the sea level by 0.5 to one metre in the next century, this rise is expected to flood 30% of the city, which will definitely cause damages to humans, buildings, and the agricultural land through salinization .
In conclusion, climate change have different effects on the agricultural sector in Arab countries. However, the expected effects of climate change on Arab countries vary from one area to another. These effects can be summarized by region as
Global Warming, much of what does or does not happen forty years from now rests on our actions or inactions taken between now and then. The crucial question is whether we should pour all our resources into mitigation – reducing our carbon emissions. According to scientists who study the climate there are other environmental problems; “we now face a global crises in land use and agriculture that could undermine the health, security, and sustainability of our civilization”.
In Australia the climate is expected to become significantly warmer. Noting that the impacts of climate change will vary from region to
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
Climate change refers to shifts in the mean state of the climate or in its variability, persisting for an extended period of decades or longer (Ziervogel and Zermoglio, 2009). It is the change in average atmospheric behavior, and change in the patterns of variation around this behavior (Rumbach and Kudva, 2011). The Intergovernmental Panel on Climate Change (IPCC) declared that climate change is unequivocal as evidenced by observed changes in several global and regional climatic indicators (IPCC, 2007). At the country level, climate change refers to observable changes and permutations (undefined geographic variations) of temperature, rainfall and extreme climate events and their single or collective impacts on various agricultural production (Lasco, et al., 2009).
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.
The changes in the quantity and timing of precipitation and the availability of water will profoundly affect people and other life forms. Ecosystems will change and wildlife behavior and habitat as well as crop yields will eventually be affected. Climate change will also have an impact on water-related economic activity – not just agricultural methods, for example skiing areas, may experience decreased snowfall, having an adverse impact on the economies of mountain towns and cities.
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 a long-term change in regional or global climate patterns. From the mid twentieth century to now, there has mostly been a significant increase in average global temperatures. Climate change is a major issue in the world today, and a lot of people feel very differently about the cause of it. The common argument is whether climate change is a natural occurrence or if the recent increase in temperatures is because of humans. Climate change is a natural cycle in the Earth’s weather.
According to National Geographic, Many human societies depend on specific crops for food and clothing. When the climate changes in the area that they are living, they can’t grow crops in this field.Also, scientists believe that tropical diseases will expand to some regions where the temperature is extremely high. (Natural Geographic). This shows how people who depend on growing crops for survival are affected due to the change of climate. According to gto Environmental Protection Agency, climate change affects fisheries. When climate changes, the ranges of many fishes and shellfish decreases. Marine species have temperature ranges at which they can survive. Also, diseases that affect aquatic life will occur when the water is warm. Furthermore, changes in temperature affect the timing of reproduction. For example, in the Northwest warmer temperature changes the lifestyle of salmon. This leads to a decline in salmon population. (EPA) Climate change which is caused by greenhouse gases has an enormous impact on Food
Climate change is one of the major issues surfacing on 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.
Historical temperature yield relationships indicate 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). Developing countries are said to be more vulnerable than developed countries to climate change due to already stressed marginal production environment, heightened exposure to extreme events and scarcity of capital for development and dissemination of adaptation measures (Fischer et al., 2005; Tubiello et al., 2008;) .... ... middle of paper ... ...
As defined by the Oxford dictionary, climate change is, “a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.” (Oxford Dictionaries) Moreover, evidence of climate change can be found all over the world, and in many different forms, but is especially prevalent in certain regions. For instance, in Southeast Asia, specifically the nation of the Philippines, signs of climate change can be observed frequently, if not regularly. One major ...
Climate change is the long-term shift in weather patterns in a specific region or globally. Climate change refers to changes in a regions overall weather patterns. These include temperature changes, precipitation and cloud cover (www.ecolife.com).
...o climate change. All of these have caused an impact on the ability to produce crops and grow agriculturally. Climate change has been increasing the number of droughts, floods, health hazards of employees, natural disasters, and sea level elevations. All of these put in danger the crop productivity resulting in famines and food price increments. Climate change affects agriculture in every country differently due to its location. Countries such as Canada and Russia are being affected positively by climate change since it has enabled the country to prosper agriculturally. Other countries cannot handle drastic temperature changes, such as Sudan and Bangladesh, whose agricultural growth has been affected negatively by the climatic changes. Agriculture is fundamental in a country, creating a balance between agriculture and the increasing climatic changes would be ideal.
Climate change is caused due to the release of few carbon compounds into the atmosphere, which drastically brought the weather changes all over the world. Climate change is not confined to a single region. It has become an important issue all over the world for the past few years.
