Much of the earth is degraded, is being degraded, or is at risk of degradation. Vegetation is damaged or destroyed Desertification reduces the ability of land to support plant life. Desertification is the process by which land dries up eventually over time and the land turning to desert. For example, trees can be used to preventsoil erosion and reduce polluted runoff into nearby bodies of water. When unfavourable agro-climatic conditions are combined with an absence of infrastructure and access to markets, as well as poorly adapted production techniques and an underfed and undereducated population, most such zones are excluded from development. Due to the extreme variability in precipitation levels in dry lands and various other regional climate patterns, the precise impact of human activities on desertification is difficult to identify. Today the economies of Africa are the weakest in the world, and the desperation of the rural population has also had adverse effects on the environment.
Polluted sources of drinking water Vegetation plays an important role in cleaning our water. Barren soils lack this green filter, and therefore, more of these harmful substances enter our groundwater reservoirs. Improper farming practices, for one. In a country like Burkina Faso in sub-Saharan Africa, everything comes from the immediate surrounding area. It extended from around what is today northeast Afghanistan to Pakistan and northwest India an area of 1. One less difficult solution that has been proposed, however controversial it may be, is to bring about a cap on the population growth, and in fact to turn this into a population decay, so that each year there will gradually exist fewer and fewer humans who require the land to be depleted even further in order to grow their food. A country´s wealth is built up slowly over a century, but it can be demolished in less than a decade.
It is caused by a variety of factors, such as through particularly the current and through the of soil through human activity. But what causes the removal of vegetation? Unprotected, dry soil surfaces blow away with the wind or are washed away by flash floods, leaving infertile lower soil layers that bake in the sun and become an unproductive hardpan. This means no crops for humans and no grazing crops for animals. Will this lead to the break-up of the European Union? The is a high-profile example of one method that has been finding success in this battle with desertification. Selective production and export , such as those in the European Union and the U.
One reason for land abuse is the mismanaging of irrigation, an issue of dryland agriculture for centuries. Regarding stopping desert, the first plces to plant trees, indigenous durable trees not fast growing crap for timber, is as high up as possible, where the rain usually falls first. Plantations A smaller, but none the less significant, reason for the removal of natural forests is the planting of tropical tree crops such as rubber, oil palm, and eucalyptus, more so because the rate of plantation establishment is less than rates of deforestation. Agree, The government itself is the problem. The reduce in plants causes desertlike conditions. General Assessment of Progress in the Implementation of the Plan of Action to Combat Desertification, 1978-1984.
The overriding need of the next few decades is to evolve strategies that inextricably tie conservation and development together. Also, contact the Directorate of Resource Conservation to inform them on overgrazing and poor land management. Excessive ploughing of land may also cause soil erosion. In both developed and developing countries much could be achieved through a change in attitudes toward forests - from one of seeing the potential for exploitation to one of seeing the need and desirability to conserve and make exploitation more rational and sustained and less wasteful. Worldwide, overgrazing is the main major.
Essay: What is desertification, where is it found, and what are the causes? Flooding can also negatively affect the water supply, which we will discuss next. Moreover,overcultivation of crops causes decrease in nutriens in soil,so it leads to desertification by declining soil fertility. The future is already in place. The following are a few suggestions appropriate for immediate action to fight against deforestation and desertification in a reasonably long-term perspective: strengthen the planning and organization of ecological, silvicultural, and socio-economic research; strengthen research on particular subjects such as certain social and cultural aspects of rural life, natural resource accounting, etc. Also, contact the Directorate of Resource Conservation to inform them on overgrazing and poor land management.
Events such as flooding, dust storms, and pollution, all become stronger in areas with heavily degraded soils. Furthermore, less or no rainfall adds to the drought conditions, and the climate turns hotter and drier, causing more and more desertification. Desertification is the deterioration of land in arid climates due to loss of vegetation and soil moisture. Loose soil bury plants, or their roots become exposed and cannot fulfill their function. Because of overgrazing, plants are eaten by mammals before they grow and multiply,then lands become arid.
This has destroyed many villages in its path. A shepherd guiding his sheep through the high desert outside , Scientists agree, that there is a natural cause for the existence of desert in the place where is now the : a natural climate cycle cause a lack of water in this area from time to time. The worldwide programme was aimed at stopping the process of desertification and at rehabilitating affected land. Submitted by: Justyne Gibson Social Studies Fair Project Mrs. Hence, they have serious socio-economic implications too. The following rains will again result in flash floods followed by drought as nothing left to keep the rain water long enough to provide foe any sustainable local growth. However, with an increase in degradation of land and drought in various African countries specially the southern African drought of 1992 , the need for unified international action became apparent.
These definitions are not confined to advancing frontiers of sand that engulf pastures and agricultural land, as often shown visually in the media. Furthermore,deforestation reduces the protection of soil and because of rainforest destructions there is not enough water, the surface of soil becomes arid that leads to desertification. These people include many of the world's most vulnerable, marginalized, and politically weak citizens. The immediate cause is the removal of vegetation. This paper focuses on terrestrial degradation - which may be defined as the loss of utility or potential utility or its reduction, or the loss or change of features or organisms that cannot be replaced Barrow, 1991 - and on deforestation and desertification in particular.
It is quite natural that when the land is deserted, and the number of arid and semi-arid regions goes on increasing, there is no evaporation, which ultimately results in less rainfall. This mixture varied with time, place, and culture, since the harsh conditions forced people to be flexible in their use of the land. They may essentially strip the land of everything that it has before moving on to another plot of land. In conclusion the Sahara desert is the worlds most hottest and largest deserts know today and it is obvious that as large as the Sahara is, it took millions of years for desertification to have such a. Desertification is a self-continuing process.
