Land Use And Land Cover Changes

The human race all around the world wonders if the climate is changing due to human activity or if it is just a natural occurrence. At certain parts of the Earth's surface, the climate can be observed much differently than other locations. As the years go by the average temperature of the Earth increases by little intervals. There are several different reasons why people believe the climate is changing every year. However, the increase of worldwide population and production of heat to the atmosphere is due to the increase of human activities that take place on a daily basis. Human activity is the main cause of the global climate change. The human impact on climate exceeds any known changes due to natural processes. The impact of this human activity is often misunderstood when looking at climate change.

Climate change is a issue that widely talked today. As the National Weather Service reports, the hottest temperature records are extending all over the United States since year 2010 (Schlesinger, William H, 2014). It is obvious that our world is heating. Global warming become more and more seriously. With the increase of temperature, many environment problems occur to have huge impact on our urban life, including: the sea level rise, air pollution and drought. These environment problems also endanger our area in a large part.

Due to the immense anthropogenic release of green house carbon emissions into the atmosphere, there has been and will be major detrimental effects on human resources and the ecosystem. For example, by the middle of the 21stcentury, River runoff will increase by 40% in northern latitudes and also in a few tropical areas, while in dry regions it will decrease by 30%. Some of these tropical areas have already reported and are experiencing water droughts that will only get worse (Gillman 2008). In addition, if temperatures continue to increase to 1.8-5.4 degrees, food productivity and resources will be affected. When the temperatures reach the lower latitudes of what is predicted, there will be a slight increase in food productivity for a little while. However, when the temperatures reach the higher end of the latitudes, food productivity will

“Arid and semi-arid environments, which represent a substantial portion of Earth's surface, have remained poorly studied. Yet water scarcity and salt content, changes in rainfall, flash floods, high rates of aquifer exploitation and growth of desert regions are all signs that suggest climate change and human activities are also affecting these arid and semi-arid zones” (Buis).

Climate change is influenced by the greenhouse effect which is the increase of Carbon dioxide, Methane, Ozone and Nitrogen Oxide. On one hand, the presence of these gases in the atmosphere make the earth habitable with respect to regulating the earth’s temperature. However, an increase in the concentration of these gases results in trapping energy in the atmosphere and this in turn increases earth’s temperature. “Global greenhouse gas emissions have grown since pre-industrial times, with an increase of 70% between

climate change is one of the greatest challenges of our time. It is undisputedly clear that human are partly responsible for global warming through deforestation burning fossil fuels and other changes we have caused to the land. There has not only been a significant increase in temperature across the globe but the seal level has rose 20cm in the past century alone. the (Intergovernmental panel of climate change, IPCC) has also tracked the “unprecedented recent rise in atmospheric carbon dioxide and other greenhouse gases since the beginning of the industrial revolution.” It is alarming that the emissions of greenhouse gas continue to rise globally and it is deeply concerning that all countries, particularly developing countries, are vulnerable

In all these cases, the impact of human activity on the environment has increased. Through industrialization, for instance, carbon emissions into the atmosphere in increased. On the other hand, by clearing natural vegetation for human activities, such as agriculture and settlements, the natural cycles of gases are interfered with. In all these cases, the long term effect is climate change. The impact of climate change on human life has

The term “Global change” addresses recent changes in climate and climate variability, growth of the human population, percentile of total population living in urbanized areas, safe water accessibility and storage, plus trade and travel. Due to human activity these changes are occurring on a global scale, affecting

According to Foley et al. (2005, p.570) the advent of contemporary agriculture as well as forestry has been one of the major events in human history. Whether by stepping up practices on existing forests, pastures, croplands or by clearing natural ecosystems; human land use practices are radically changing the earth’s climate as well as exploiting an even larger share of the earth’s environment in the process. In support of this, Bonan (1997, p.449) suggested that the earth’s surface is persistently modified by continued natural as well as human activities.

Change in climate is becoming a major concern on a global scale, as it has had a tremendous impact on urban environment. Oxford dictionary defines climate change as:

Climate change is a natural phenomenon that occurs over time. However, humans have accelerated the pace of climate change due to greenhouse gas emissions, compounding the greenhouse gas effect, and leading to harm to the planet (United). This paper will focus on human-caused climate change. Climate change has the potential to impact all levels of society, ranging from the individual to businesses. Climate change has serious implications for health and wellness, the economy, agriculture, and infrastructure, along with other aspects of society. Given the rapid pace of climate change due to global warming, societal changes are necessary. It is impossible to expect society to continue to flourish in the face of a changing planet if adaptation does not occur. This adaptation must promptly take place on the part of both individuals and larger entities.

Climate change is viewed as new global threat for the population all around the world. Climate change can be define as “Disturbance in environment and climate patterns with respect to increased level of atmospheric carbon dioxide, methane and nitrogen ratio”. Climate change is now tagged as critical security problem for present and upcoming generations with the passage of time. It is now predicted that these climate changes will increase the risk of violent conflict. Climate change is not only affecting the quality of life, but it is also causing limited access to natural resources that are essential in sustaining human life. It is also restricting access to opportunities and services that are helping people to retain standard quality living conditions. Disturbance in ecological and social system is a threat to living lives that have greater dependency on natural resources. These negative changes are dangerous and sudden transitions are threatening basic relationship between human security and social system.

In fact, since the beginning of the industrial revolution, human activities such as the burning of fossil fuels, deforestation and agriculture have caused the concentrations of greenhouse gases in the atmosphere to increase substantially. A marked rise in the global temperature has been related to these human activities and CO2 emissions, and this temperature rise is believed to be the result of an enhancement of the natural Greenhouse effect. And as a result, global warming arises.This awareness has led many researchers to investigate possible causes and effects of this temperature rise. However, as much knowledge about the climate system is lacking, numerous researches on that issue have led to a great deal of debate. At the moment, the way the climate system will respond to these human activities is difficult to predict, for too many processes are not understood well enough. One absolute reality though is the fact that the global climate system will respond to increasing temperatures. Moreover, this response could have irreversible consequences for the habitability

One cannot shy away from the fact that climate change has been caused by some of the human-based activities on the environment. These activities have been at an increasing rate over the past years generated a wave that cannot be stopped by anyone since our natural environment is no longer independent, but being interfered by humans. We know that different economies are trying their best to up their game through urbanization, technological advancements, and globalization, however, it is not all good at all since there are alterations in both the economic and social patterns on the globe. Land, air, and water are the top most endangered natural resources in the environment since their degradation is increasing each day and every night (McMichael & Confalonieri, 2015).

Nowadays, one of the most difficult problems is Global Warming. It is obvious that increasing in earth's temperature has made significant negative effects on earth's climate during the last few
