Desertification covers the entire process of major land degradation, with deserts being the ultimate stage. Desertification control, mitigation and reversal will be a difficult and long-term process, and the government should continue to play and enhance its roles (Qi et al., 2012). Despite being closely related, drought and desertification are different. Build these at gully heads as well. Desertification is indirectly linked to global warming and all other environmental changes. Desertification has been described as “the greatest environmental challenge of our time” and climate change is making it worse. Desertification is a process by which fertile land becomes desert, typically as a result of drought, deforestation, or inappropriate agriculture. 1) What is involved ? They now cover about 5 million square km (about 2 million square miles) and account for roughly one-third of all croplands worldwide. The ways to control desertification are crop rotation, controlled grazing and wind brakes. However, the current desertification control measures only focus on re-establishing vegetation and controlling soil wind erosion, and fail to explore the direct causes of desertification. Seventy percent of the African continent is subject to desertification. How desertification can be controlled? Desertification can mean two things. Desertification can be reduced by adopting the following strategies: Planting more trees - the roots of trees hold the soil together and help to reduce soil erosion from wind and rain. Crop Rotation: Crop rotation is the cultivation of different crops in a specified order on the same fields, in gap to a one- crop system or to random crop sequences. The United Nations Convention to Combat Desertification (UNCCD) came into force in 1996. Before cultivation, such areas were often vast grasslands. Runoff is concentrated into a narrower area as it travels across lands. Desertification affects as much as one-sixth of the world's population, seventy percent of all … The National Desertification Control Office is located in the Ministry of Forestry in order to coordinate regular programmes and activities; coordination points have been created at different levels of local government. Unrelated to the Volcani, but located nearby in Rehovot, is the Faculty of Agriculture of the Hebrew University. Worldwide, desertification affects about 1 billion people and 2 billion hectares of land -- an area the size of the United States and Canada combined. Each member of the Qiemo Desertification Control Station is in charge of 66.7 hectares of forests and each 0.067 hectares of forests has nearly 300-meter long drip tube, so each member has to take care of about 300,000-meter long drip tube. Ningxia Hui Autonomous Region, in northwestern China, has been in a battle against the desert since the 1950s. Such declines may be the result of climate change, deforestation, overgrazing, poverty, political instability, unsustainable irrigation practices, or combinations of these factors. Firstly, it can mean the process of expansion of an existing desert. Desertification is a type of land degradation whereby previously fertile soil is transformed into arid land. Salinization of irrigated land is still occurring and the dryland saline seep problem is getting worse. Desertification, then, we can infer, is the process by which a space becomes a desert. 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 … You can build a paved flume, or lined channel, to lead the water to a safe drainage system. Since overpopulation indirectly contributes to desertification through excessive pollution and a contribution to global warming, population control measures should be taken in order to mitigate this issue. Population control. The loss of fertile land to desertification has brought an end to many majestic civilizations throughout the human history. Desertification is the process through which fertile land becomes desert. The UN maintains that 1.5 billion people are affected by desertification. At present, desertification probably has been stabilized, with some improvement in plant cover of rangelands and in control of erosion and waterlogging over the past 30 years. 8. Over … It is a global issue of huge importance, though its effects are felt especially strongly in Africa. Defining Desertification and Drought. A shift to renewable energy sources like solar power is … Desertification, the process by which natural or human causes reduce the biological productivity of drylands. Jianlong said this at a UN Convention to Combat Desertification (UNCCD) meeting held in Guiyang, capital of southwest China’s Guizhou Province. 10 top ways Israel fights desertification ... as well as pest resistance and biological control methods that use fewer resources and chemicals. It can be caused by climate change, drought, and irresponsible agriculture practices. 2) Who use this means ? Desertification - Desertification - Rain-fed croplands: Drylands also support rain-fed crops. Figure 8 Severe soil erosion leads to desertification As we have seen throughout this topic, soil erosion often goes hand in hand with desertification. Presenting simple methods, especially in terms of soil arrangement, to control drought and desertification. Changes in lifestyles and practicing sustainable practices like saving energy, water and reducing waste eventually leads to a decrease in desertification. Control of Desertification: 1. As the effects of climate change undermine livelihoods, inter-ethnic clashes are breaking out within and across states and fragile states are turning to militarization to control the situation.

"Desertification is a fancy word for land that is turning to desert," begins Allan Savory in this quietly powerful talk. This work aimed to review the aspect of desertification, its concept, causes and its control with special reference to Sudan. This project is to control the fast-growing desertification in Inner Mongolia. control models of desertification, especially the numerous results from research carried out for the UN Convention to Combat Desertification. Hassan reiterated the Federal Government’s commitment to empower the communities to control desertification, address unemployment and check rural-urban drift. "In short, each of us has to walk more than 20 kilometers every day for patrolling the woods," said Yasin. For instance, this could mean setting restrictions for … China’s practices in desertification control could provide valuable knowledge for sustainable desertified land management on a global scale. A World Bank-supported project has been helping to control desertification, revegetation, and introduce other ecological protection measures. Desertification includes land degradation in arid, semi-arid and dry sub humid areas resulting from various factors, including climatic variations and human activities. Therefore, desertification control should not concentrate only on enhancing the carrying capacity of desertified lands but also on decreasing population pressure. China’s Law of Prevention and Control of Desertification is the world’s first integrated law dedicated to combating desertification. The points where the concentrated runoff reaches a slope are particularly vulnerable to erosion. Other than stopping desertification and erosion, the wall would protect water sources, such as Lake Chad, which has been drying up for decades, and restore or create habitats for biodiversity. oj4. It appeared that there was a wide controversy among scientists on the concept of desertification and its causes. China plans to help control desertification along artery roads in eight Central Asian and African countries, said Zhang Jianlong, Director of the National Forestry and Grassland Administration. The main activity is to implement the program that can lead to financial independence for the local residents and its community, in addition to the greening activities to restore their grassland.
