The demands for natural resources will increase day by day as the population increases the demand for consuming natural resources also increases. As human interference with nature will lead to the degradation of our environment. Clear cutting the forests for development has already caused a threat to the biodiversity and many other natural resources. In this case it becomes very important for us to manage our natural resources for future generations. We are facing many environmental challenges, and it is very important to make
Human intervention has caused many dysfunctions to the environment, some of which have left damages on the ecosystem that eliminates other sources of necessity to other living things. Ever since humans start to harvest the Earth 's resources, many landscapes have been altered to fit the lifestyles of countless inhabitants. So people ought to be aware of other types of environmental challenges that the planet is facing. Some of the challenges that the planet is facing include overpopulation of human beings that leads to natural resources depletion, deforestation and loss of biodiversity, acid rain and ocean acidification, pollution and waste disposal. Every citizen of this earth has to overcome these challenges together in order to conserve, restore and preserve this damaged ecosystem.
1.0 GENERAL INTRODUCTION Deforestation especially in the tropics has been one of the resultant forces of land use change in the world today and its avoidance has not been realized eligible as a Clean Development Mechanism (CDM) in the Marrakesh Accords. Avoidance of deforestation is not yet eligible as CDM activity mainly because of leakage related issues (Kanninen, et al., 2007). Deforestation involves a permanent process of land-use change which could be a result of forests conversion into croplands and pastures. However, the process of deforestation could also be a temporary or partial forest trees removal due to shifting cultivation and selective logging (Moutinho & Scwartzman, 2005) i.e. converting forest from its original course to
Abstract: - The paper examined the relationship of population to the environment and with growing population, poverty and urbanization the environment is degrading. Conducted an analysis of changes and trends over last fifty years, the study reveals that the country 's population growth is imposing an increasing burden on the country 's limited and continually degrading natural resource base. The natural resources are under increasing strain, even though the majority of people survive at subsistence level. Population pressure on arable land contributes to the land degradation. The increasing population numbers and growing affluence have already resulted in rapid growth of energy production and consumption in India.
Deforestation is a problem that is increasing dramatically over years leading a lot of effects that are harmful for the earth, animals and humans. There are a few problems that cause deforestation. First of all is the necessity of build infrastructure including houses and roads. Nowadays the demanding of new infrastructure is steadily growing that is why people need to log trees. Another reason why deforestation occurs is because climate change.
Let’s take Mali and Nigeria for an example. Mali and Nigeria are two countries in West Africa with great potential to increase their agricultural production. However, they have also recently experienced severe episodes of internal conflict, which have negatively influenced agricultural productivity and investment. Conflict can adversely affect agriculture in several ways. For example, conflict can disrupt the supply and distribution of inputs and outputs create price shocks and cause massive displacement of labor.
On the face value, one is prompted to conclude that Egyptians’ migration is anchored on unfavorable economic situations. However, closer inspection reveals that environmental degradation is a major cause which sees people move from region to region in Egypt. The study centers on how the environmental and climatic conditions arising from natural and man-made factors cause economic crisis. Afifi therefore points out that the economic situations in the Northern Africa, with particular concern to Egypt, causes migration with environmental factors as the root causes. This study is important to this paper because it illustrates how environment significantly impacts on the migration of people which consequently influences the economic system of a
Firstly, population growth is a major factor of deforestation because the demand for basic commodities such as food and shelter is likely to increase. Deforestation begins with human settlement escalating in near-forest areas which they produce their own food through subsistence agriculture. The use of traditional farming methods, the slash and burn technique by small-scale farmers is deemed destructive as suggested by Golden and Miller (1994, p. 14). This can be dangerous because these fires could expand and burn the remaining forested territories that they border and the affected soil is no longer suitable for farming. For instance, there was 62 000 square per kilometer of forest in Madagascar, but the current forest cover is only 10 000 square per kilometer (RAN, 1999).
1. Introduction: Adverse and unpredicted climatic conditions are the leading cause of the food security worldwide. It has adverse effects on water resources, crops production, hydropower, and human health worldwide (Nelson, Rosegrant, Koo, Robertson, Sulser, Zhu, & Magalhaes, 2009). Globally, the climate is changing rapidly over millennia but from the past few decades, greenhouse gases emission (GHG) have increased due to anthropogenic activities such as deforestation, land degradation, burning of fossil fuel and industrial revolution (Baig, & Amjad, 2014). Different factors are playing their role in the GHG emission but agriculture land is also considered a source of GHG emission (Rosegrant, Ewing, Yohe, Burton, Saleemul, & Valmonte-Santos,
Uwatt’s assertion is axiomatic in that these activities have manifested their negative effects in the ravaging soil erosion which has come to constitute a serious plight to Nigeria’s ecological landscape and Nigerians over the recent years. These devastating activities of man, Nwadialor posits, manifest their overall impact in the “destabilisation of the natural equilibrium, of environment− which in most cases end up in environmental pollution”(69). From every indication, deforestation can be considered the springboard of the mind-boggling damage wreaked by the 2012 flood which left thousands without shelter, and in which the funds that would probably have been used to provide infrastructure or meet other needs were dissipated on the aftermath of the evitable flood. The cutting and burning of trees has also contributed immeasurably to
