Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly more arid. It is the spread of arid areas caused by a variety of factors, such as through climate change (particularly the current global warming) and through the overexploitation of soil through.
The loss of fertile land to desertification has brought an end to many majestic civilizations throughout the human history. For example, the destruction of the native tropical forest in the Indus Valley opened up a pathway for the desert to claim more and more land, leading to.

Chad had secured a $ million credit from the IMF in Junebut release of those funds hinged on restructuring the Glencore debt. Chad had already cut public spending to try to meet the terms of the IMF program, but that prompted strikes and protests in a country where nearly 40% of the population lives below the poverty line.

Africa, the second-largest continent, is bounded by the Mediterranean Sea, the Red Sea, the Indian Ocean, and the Atlantic is divided in half almost equally by the Equator.
Africas physical geography, environment and resources, and human geography can be considered separately. Africa has eight major physical regions: the Sahara, the Sahel, the Ethiopian Highlands, the savanna, the.
Human Population Growth "The massive growth in the human population through the 20th century has had more impact on biodiversity than any other single factor." --Sir David King, science advisor to the UK governmentA first look at 8 Billion Angels.
8 Billion Angels OFFICIAL TRAILER from terry spahr on Rewilding Institute Position on PopulationThe core assumptions [ ]. INTRODUCTION. Humans have sought to understand the relationship between population dynamics and the environment since the earliest times (1, 2), but it was Thomas Malthus’ Essay on the Principle of Population in that is credited with launching the study of population and resources as a scientific topic of s’ famous hypothesis was that population numbers tend to grow Author: Alex de Sherbinin, David Carr, Susan Cassels, Leiwen Jiang.
Desertification can be prevented if educations and learning are spread to the population. Teach the population how to farm and how to carefully use the resources is the first step to preventing land degradation. The society will be in a better shape and healthier conditions if the environments are clean and well taken cared of.

An overview of studies conducted in the s and s reveals a strong relationship between population growth and deforestation in Central America, East and West Africa, and South Asia, but a much less clear association in Amazonia (South America) and Central Africa.

Desertification is the process of ecological degradation by which economically productive land becomes less productive, in some cases leading to the development of a desert-like landscape.

Michener. Imeson, A. Desertification, Land Degradation and Sustainability. Hoboken, NJ: Wiley, DOI: / E-mail Citation» This book focusses on how desertification processes operate at different scales (local to global) and how adaptive management decisions need.
In Sub-Sahara Africa the society is altering due to desertification and the effects it has on society and furthermore desertification is easy turning and it is a chief job in Africa due to the African tropical conditions and the sloppiness of the people ‘s work toward the land.
The same kind of deforestation is occurring today in tropical rainforests, which are cleared to develop cropland to feed a burgeoning population. The effects of tree loss on soil are significant.
Trees and shrubs shield the ground from the force of raindrops and provide shade that reduces surface soil temperature, which in turn reduces evaporation. this result is desertification. According to our book, Discovering Physical Geography, desertification is “the process through which a formerly vegetated landscape gradually becomes desert-like (Page number).” The process of desertification is an ongoing issue that has inflicted major harm to landscapes all around the globe.

Oliver and R. Fairbridge, eds., Hutchinson Ross. The relationship between population growth and growth of economic output has been studied extensively (Heady & Hodge, ).Many analysts believe that economic growth in high-income countries is likely to be relatively slow in coming years in part because population growth in these countries is predicted to slow considerably (Baker, Delong, & Krugman, ).
2. Promote family planning. Simply educating men and women about contraception can have a big impact. When Iran introduced a national family planning programme inits fertility rate fell from births per woman to in a decade.
A similar effort in Rwanda saw a threefold increase in contraception usage in just five years. There are over 7 billion reasons to include population studies in your classroom.

A new and more effective approach was required at all levels within the framework of sustainable development. Fertility, growth rate, population density, and population by age group, from by country and year. Measure DHS USAID's Demographic and Health Surveys collects data on population, contraception practices, maternal and child health, HIV, nutrition, education, and more in over 90 countries.
Desertification is a term that has been in use since at least when Aubreville, a perceptive and well-informed botanist and ecologist, published a book on "Climate, Forets, et Desertification de l'Afrique Tropicale" (Aubreville, ).
Population pressure, a rate subject to slight variation depending on local death rates. is the point of “leveling off” that population projections foresee when a society has completed the demographic transition.
Desertification may become a more serious problem in coming decades. Causes and Impacts of Land Degradation and Desertification: Case Study of the Sudan.
Desertification. Desertification has been defined as land degradation in arid, semi-arid, and dry sub-humid areas resulting from various factors, including climatic variations and human activities.
