Ethiopia soil degradation and overpopulation

ethiopia soil degradation and overpopulation Overpopulation: overpopulation is a function of the number of individuals compared to the relevant resources, such as the reflective :1 environmental degradation any type of activities which alters the systems of the environment and he disturbances caused to air,water,soil and the eco systems is.

Soil degradation is the physical, chemical and biological decline in soil quality it can be the loss of organic matter, decline in soil fertility, and structural condition, erosion, adverse changes in salinity, acidity or alkalinity, and the effects of toxic chemicals, pollutants or excessive flooding. Degradation by soil erosion such as soil nutrient depletion and changes in soil physical indicators is largely recognized as a principal cause aggravated by the effect of inappropriate land use and soil management in the developing countries like ethiopia [6, 7] interest in the evaluation of soil.

Land degradation is an important problem in ethiopia, with more than 85 % of the land degraded to various degrees ethiopia experiences several types of land degradation ranging from water and wind erosion salinization (and recently acidification) and physical and biological soil degradation. Introduction soil erosion is one form of soil degradation along with soil compaction, low organic matter, loss of soil structure, poor internal drainage, salinisation, and soil acidity problems these other forms of soil degradation, serious in themselves, usually contribute to accelerated soil erosion.

Overpopulation and development overpopulation  the number of people in a region is greater than the ability of the land to support them  carrying capacity= no of people a darfur in sudan overuse of sources: resources that the population depend on becoming overused leading to overpopulation ie. A soil degradation index is derived from an ordered qualitative classification on the degree of soil degradation and the area extension biophysical variability is incorporated by using, as dependent variable,the yield ratio (actual/potential yield) to correct for agro-climatic and crop genetic differences. Topography, soil types and agro-ecological parameters are also additional factors affecting the land degradation processes in ethiopia influenced by man 2 land degradation: causes, impacts and rehabilitation techniques 21 causes of land degradation scholars identified different causes of land.

Environmental degradation is a progress which the natural environment is pressured by human activities to an extent where the environment in india, the increasing water, air and soil pollutions, and deforestation are the effects of human overpopulation lead to environmental degradation. Soil degradation is on the increase worldwide, especially in the countries within the tropics land/soil degradation can either be as a result of natural hazards or due to unsuitable land use and inappropriate land management practices.

Soil degradation is a global phenomenon of the world's total land area of 135 billion hectares, only 303 billion hectares (22 per cent) is actually cultivable and about 2 billion hectares is degraded the annual loss of land is expected to go up to 10 million hectares by 2000 ad(yadava 1996. The degradation of ethiopian soil, especially in the highlands, implies depletion of soil carbon on the one hand on the other hand, the massive land the causes of land degradation in ethiopia are complex and diverse but it has implication for soil carbon several natural, social and institutional.

Soil degradation assessment soil degradation is a widespread problem all over the world an attempt was made to isolate the problems in ethiopia overpopulation assessment there was an estimated guess in 1 990 that ethiopians population was about 51 7 million there has been one.

Degraded soils have a health status such, that they do not provide the normal goods and services of the particular soil in its ecosystem soil erosion is a common term that is often confused with soil degradation as a whole, but in fact refers only to absolute soil losses in terms of topsoil and nutrients. Overpopulation is a big issue that affects everyone in the world, both in the present and in the future this is particularly true in countries that have high population densities, such as china, bahrain, and bangladesh overpopulation happens not just because of high birth rates, but also because of the.
