The earth has been in a state of continuous change since a long time ago. Land-use and land-cover changes (LULCC) induced by human and natural processes a major role in global as well as regional scale patterns of the climate and other aspect of the earth system (Ramachandra et al., 2012). Now a day’s Global warming is highly increasing because of massive land-use land-cover (LULC) changes and land-cover by itself is a fundamental variable that affects many aspects of the natural environment. The change in land-use land-cover leads to environmental change, rainy season fluctuation, increase sea surface temperature (SST) and land surface temperature (LST). This massive land-use and land-cover change is due increase the need of land for settlement and agricultural. Land is scarce (limited) natural resource, which cannot be changed when the number of population increases. Land-use should correspond to land capacity and at the same time it should, respect global climate system and the environment (FAO/UNEP, 1999). Land-use is converting over time and the most important driving force of land-use changes is the human need. Human population is increasing and it causes transformation of natural ecosystems into human landscapes. Human settlements, the need for farmland and, especially, industrial areas and large urban areas significantly modify their environment. Changing from permeable and moist land uses to impermeable and dry one with paving and building material can have a
Throughout Cronon’s novel, Changes in the Land, he addresses the many ways that the colonists affected the environment of the new world and its inhabitants. He accomplishes this by concentrating on the history of this time period while still including references to the science and ecology that help to fill in the blanks of the information not supplied by historical documents, letters, and other records kept by the colonists living in New England at the time. Using information and documents from the colonists, we are able to get an idea of what the area of New England looked like at that time, but due to inaccuracies and biases on the part of the colonists we can’t be sure that our view of the area is completely accurate. Cronon makes these

Annotated Bibliography: How Climate Change Is Affecting Our Planet Controversy statement: Climate change is been debated for over centuries now. People all around the world are taking action and reducing burning fossils to minimize the gasses in the atmosphere. Many people believe that climate change doesn't exists. But there are a lot of controversial topics that proves that climate change is real. In my opinion, climate change is slowly killing us and destroying our planet.
Landslides may cause the loss of lives and properties. Deforestation causes the soil to lose its stability. Decreasing of trees causes there is lack of tree leaves to protect the soil from the collision of raindrops and also causes the lack of tree roots to hold the soil. Thus, the soil is exposed directly to the raindrop. The top layer of soil is easily washed away by the heavy rainfall.
Global warming is a big problem that we have to face nowadays. If you search Google for the word “global warming’, you will get over 70 million pages of results. The subject has certainly drawn a lot of attention. And now I will talk more about “what is global warming” , the cause and the effects it has on the earth and also some possible solutions for this problem.
Objectives of study 1. Study the factors causing the rise in global warming. 2. To analyze the consequences of this constant inclination in the temperature of earth. 3.
Over population often puts pressure on a country to produce more. This leads to poor farming practices, overgrazing and monoculture. The constant land degradation and low rainfall causes desertification in arid and semi-arid areas. The desertification results in unproductive farmland which increases the pressure to produce food even more.
Agriculture is the modification of Earth’s surface through the cultivation of plants and animals through the cultivation of plants and animals to obtain economic gain. It was also a key development for the rise of the domestication of animals. Although, its origins cannot be documented for certainty because agriculture began before recorded history, scholars believe that it was started in Southwest Asia. Also, agriculture entails selective breeding of animals with combinations of inherited characteristics that benefits humans. Around the world, agriculture’s steps are the same, but the type of animals that were raised or cultivated differently.
Introduction Overpopulation is the excessive population of an area to the point of overcrowding and it is an undesirable condition in every country where the number of existing human population rises to an extent exceeding the carrying capacity of ecological setting. Overpopulation can be result from an increase in births, an increase in immigration, a decline in mortality rates and other factors that may cause overpopulated environment. Therefore, this can cause influence as lack of the available essential materials for survival like water, shelter, social amenities and other because of the numbers of people might be more than the materials for survival. In such condition, this regularly contributes to environmental deterioration, worsening
Climate change is the most rising issue of the modern world that is threatening our planet from the last few decades. In the simplest definition, the term climate change refers to the rising of the planet’s temperature, particularly an increase in the average atmospheric temperature. It should be noted that in the last few decades, many scientists and ecologists has discovered the Earth temperature is increasing at an alarming rate and has affected the planet in numerous of way. The constant change in the climate due to various causes is threatening the preservation of the Earth and its human life. It should be noted that the climate change is linked with several of the human activities that are further directed towards the global warming.
2.8.2 Urbanization Urbanization led many areas becomes more modernized. Lowland areas have been reclaimed by taking land from the hills. There are also small rivers that filled up to be used as a building site. Activities such as these are a common factor of flooding. In the past, creeks and valleys turned into water flow, now the area has been covered with soil.
Researches show that the average temperature of the planet has been changed during the last decades, as a result, many problems join with it and climate change is considered as the biggest problem around the world. Climate change is one of the results of global warming and it has so many negative disadvantage impacts on earth, including; increasing the events of natural
And one of the old solutions for this concern is to increase number of cultivation lands and exploit new fish stocks. But the competition for land from other human activities makes this an increasingly unlikely and costly solution .for example food producers are experiencing grater rivalry for land, water energy and the need to curb the many negative effects of food production on the environment becoming increasingly clear (Tilman et al. ,2001;
Global climate change constitutes arguably the single most important threat to mankind. From the onset of the industrial revolution, greenhouse gas emissions (GHGs), including carbon dioxide (CO2) have increasingly built up in the atmosphere, causing the climate to warm up slowly but steadily (IPCC, 2014). NASA predicts that 2016 will mark the hottest year on record. The effects of global warming are ubiquitous: Greenland’s glacier and the Arctic ice cap are melting, ocean levels are rising, occurrences of extreme weather are increasing, including hurricanes and areas of either intense drought or flooding. Collectively, these changes and their direct consequences are an imminent danger and they directly affect other urgent issues humanity is
Background Jakarta has a population of about 9.6 million people and in the last three decades, urban development of Jakarta has grown very rapidly in many sectors starting from industry, trade, and transportation until real estate. The increase in Jakarta’s population and urban development had cause several environmental problems including land subsidence. Land subsidence is a gradual settling or sudden sinking of the Earth 's surface owing to subsurface movement of earth materials. The level of soil in Jakarta is slowly degrading due to the disturbance of the soil consistency, and the water level in the soil is slowly decreasing, and now the sea level in Jakarta is higher than the ground level. In another word, Jakarta has been experiencing
