The features of desertification and its reasons

Stone walls are placed around the trenches to prevent the trenches from closing up again.

What is Desertification?

This is driven by a number of factors, alone or in combination, such as drought, climatic shifts, tillage for agriculture, overgrazing and deforestation for fuel or construction materials.

Firewood and charcoal are examples of wood being used as fuel. Trees play a major role in controlling global warming. Their economies are powerless to break the fatal cycle of poverty that leads them to face up to emergencies by taking on more and more increasingly untenable debt.

Read here more about 51 facts about deforestation. This will allow water to be managed at the scale of entire river basins and help determine how industry, agriculture and mining can fairly share this limited resource. The establishment of biosphere reserves, forest reserves and national parks to protect the environment is commendable, but this does very little to help the people who have no other place to go.

This is not intended to say that range abuse is not taking place on some ranches, because it is. Climate change plays a huge role in desertification. It also has suitable habitats for various endangered species. However, limited controlled fires can play an important role in the management of dryland herding and farming systems, promoting nutrient cycling and forage quality.

They hereby create a symbiotic relation with the trees, increasing the surface area of the tree's roots greatly allowing the tree to gather much more nutrients from the soil.

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.

But agricultural production will also have to become more efficient. In other cases, when policy and market conditions were favorable, it led to positive interactions between the two groups. Our misuse and abuse of land and water is changing fertile land into deserts.

There is evidence that the desertification process has taken place which has resulted in some undesirable water regime and vegetation changes. Additionally, properly spaced and pruned trees can increase crop yields.

For some, there are numerous barriers to their implementation. This wall is a much larger-scale version of what American farmers did in the s to stop the great Midwest dust bowl.

These salt-flats are one of the most promising desert areas for seawater agriculture and could be revitalized without the use of freshwater or much energy. Paleodeserts are large sand seas now inactive because they are stabilized by vegetation, some extending beyond the present margins of core deserts, such as the Saharathe largest hot desert.

Considering that rangelands are producing only a fraction of their potential due to degradation, it is very likely that they are not meeting national demands and needs for whatever reason.

The second strategy is to sell off everything owned, including agricultural equipment, to cope with the monetary needs of development e. This results in mass migrations out of rural areas and into urban areas, particularly in Africa.

These migrations into the cities often cause large numbers of unemployed people, who end up living in slums.

Desertification

When it rains, trees absorb and store large amount of water with the help of their roots. In Jordan, it was estimated that Bedouins annually uproot million fodder shrubs just for cooking and in the Sudan, million acacia shrubs are annually destroyed for the same purpose FAO, Decision-makers are understandably averse to invest in arid zones with low potential.

This usually strips the soil of nutrients, which in turn kills the plant life, which in turn starts the process toward becoming a desert biome as time goes on. Most people associate dryland regions with a hot and dry climate. These can be reversed and crop production increased with implementation of improved cultural practices.

Studies have shown that, in many environments, the rate of erosion and runoff decreases exponentially with increased vegetation cover. In some areas, the increase in cultivation has been driven by increased irrigation which has often been unsustainable.

Water erosion and reduced soil conservation in semi-arid Burkina Faso negatively affects ecosystem services Source: By putting these together, we can prevent the issue from becoming even more widespread in the areas that have already been affected.

According to Chinese reports, there have been nearly 66, trees planted in China's great green wall. Environmental organizations [54] work in places where deforestation and desertification are contributing to extreme poverty.Desertification can have far reaching physical and socio-economic impacts in the affected areas.

Fighting desertification in China

Physical impacts The direct physical impacts may include increased frequency of wind and water erosion of soil. Desertification in China is a major problem for Beijing, as the country’s deserts are growing, threatening environmental, economic, and political stability.

The Green Wall of China Following the creation of the People’s Republic of China (PRC) inthe country embarked on. Context - Desertification is the persistent degradation of dryland ecosystems.

Desertification Top 10 List

It threatens the livelihoods of some of the poorest and most vulnerable populations on the planet. Desertification is largely caused by unsustainable use of scarce resources.

“Desertification is a type of land degradation in which a relatively dry land region becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife. It is caused by a variety of factors, such as climate change and human activities. Rocky features of Southern Africa include plateaus and mountains, such as the Drakensberg range.

Southern Africa is the epicenter of Africas well-known reserves, which protect animal species such as lions, elephants. Synopsis. Mongolia’s efforts to combat desertification are outlined.

There is a new action plan and a strategy is in place. Legislative reform has sought to make new provisions for securing land users rights and securing tenure over grazing lands.
