These plans include methods of rotational grazing, when certain areas are left to rest for up to two years, with replanting of native plants and shrubs where needed. Cancer rates and mortality, types and causes, Endocrine disrupting properties of pesticides. This paper takes a fresh look at two of the major environmental hazards affecting the planet, namely deforestation and desertification, in terms of the nature and magnitude of the problem as faced by the developing world, and their causes and effects. Generally used definition of drought says that it is a period of unusually low precipitation that is long enough to cause water scarcity and deplete soil moisture to the point where vegetation (including crops) dwindles [1]. Mixed farming practices in these zones, whereby a single farm household combines livestock rearing and cropping, allows a more efficient recycling of nutrients within the agricultural system. There's hope, though. In fact, natural deserts do not even have to be close to areas where desertification happens. The current practices of land management that have been implemented since the beginning of conventional agriculture consist of either over grazing or no grazing also known as over rest. Over grazing by livestock, such as cattle, sheep, and goats leave the soil bare with minimal chance for recovery due to the extreme daily changes in temperature within the soil microclimate. No grazing or over rest causes hardened algae to form on the surface, which increases runoff and prevents plants from getting sufficient water. Overtime, plants will decay via oxidation and the soil becomes bare for the same reasons already stated. Both practices lead to the same end result of desertification. From above mentioned examples, we can also tell that there isn’t one universal solution that will work in all affected areas. The results from both of these grand projects seem wonderful, but in both cases appears also criticism and doubts about the data consistency and possible consequences of such a large-scale ‘artificial’ transformation of the landscape. Found inside – Page 160Could the process of desertification be reversed, or at least be controlled? There has been a persistent tendency to look at desertification in a literal, linear fashion as the relentless “advance ofthe Sahara,” in the process ... Deforestation and desertification in developing countries. What is desertification, and can it be reversed? Furthermore, dead plant material also covers soils and protects them from drying out, while at the same time supplies soils with organic material and nutrients released during its decomposition [15]. Because dryland desertification can be remedied . Major policy interventions and management approaches are needed to prevent and reverse desertification. In order to prevent and reverse desertification, major policy interventions and changes in management approaches are needed. According to the Right Livelihood Award Foundation, by employing these methods, Sawadogo has planted 40 hectares of forest, creating a self-sustainable ecosystem on previously barren land. We don't have to relearn the lessons of past . Land degradation and desertification are global problems and that can be reversed through international cooperation. Methods, that had been once forgotten, have actually proven to work amazingly well in restoring degraded lands of the Sahel. According to some scientists this is problematic in already dried out and damaged regions like these, because if there are too many trees out of sudden, they draw too much water from the ground and actually exacerbate soil dryness, stealing remaining soil moisture from crops and other vegetation [10,11]. Zai involves digging up a hole of two to five inches deep (5 to 15 centimeters) for each plant. Fortunately there are solutions, and governments (local, state and federal) have a real and measurable opportunity to not only pioneer an approach to land management that would mitigate the perils of climate change, but also do it while generating more income for both the public and private sectors. Desertification is a problem because 40 percent of the earth’s surface is susceptible to this form of land degradation. 1. This measure helps to catch and store rainwater directly where it is needed–in the soil by the plant’s roots. Will they leave? Such strategies should be employed at the local and global level in an effort to prevent, reduce or reverse the process of desertification. Improved ecology, which will promote greater diversity in plant and animal life, Reduce or eliminate erosion caused by wind and rain, Reduce or eliminate the need for animal confinement facilities, Heal lands that have been impacted by construction activities, Position forward thinking government agencies to be at the vanguard of climate change mitigation, An improved ecology rather than bare ground, lands would become more desirable to developers, ranchers, farmers, and recreationalists. As the UNCCD states, partnerships and cooperation at all levels are needed at this moment. Found inside – Page iiSome 45 papers were delivered at the conference, falling into the categories of this volume: Overview, Potential Germplasm for Arid Lands, Introduction, Domestication and Dissemination of Arid Land Plants, Land Rehabilitation, and ... Desertification has been described as the "the greatest environmental challenge of our time" and climate change is making it worse. This volume deals with land degradation, which is occurring in almost all terrestrial biomes and agro-ecologies, in both low and high income countries and is stretching to about 30% of the total global land area. Can desertification be reversed? Scientists still question whether desertification, as a process of global change, is permanent or how and when it can be halted or reversed. As recognized by the UNCCD, such interventions are to be implemented at local to global scales, with the active engagement of stakeholders and local communities. Naturally, herbivores cover long distances during the day, grazing along the way, trampling vegetation, spreading seeds, maintaining diversity of plants and fertilizing soil with their dung. Desertification can also be avoided by creating economic opportunities in drylands urban centers and areas outside drylands. Desertification is the process through which fertile land becomes desert. Applying a combination of traditional technology with selective transfer of locally acceptable technology is a major way to prevent desertification. A common example of crops that complement each other is maize and beans. Despite of looking horribly dry and damaged, natural drylands will turn green and lush again; soils will mend; water creeks will start flowing and wells will refill with water. It uses a planning procedure for grazing herds that mimics the movement and grazing patterns of the wild herds of old, minimizing . For example, Food and Agriculture Organization (FAO) recommends planting Mesquite trees on grazed lands, which is a leguminous plant that provides pods rich in protein. It can be caused by climate change, drought, and irresponsible agriculture practices. Thanks to the cooperation of the International Fund for Agricultural Development with the Bedouin herders, 930 thousand hectares of the steppe have been regenerated and another 320 thousand are in the process of restoration [8]. For generations researches have concluded that both wild and domesticated grazing animals are a major cause of desertification, which is generally true. What researches have failed to understand is that the grazing animals are not the problem. And how can we prevent the problem getting any worse? This means that desertification could destroy everything we need for our health and survival, everything that brings us joy as well. In 1867, Mark Twain described Israel as a "desolate desert", but through new techniques in irrigation and farming, as well as reforestation in the Negev, significant gains have been made over the last hundred years there. Alvaro del Portillo 12.455 Santiago, Chile Like the benefits of increased education or improved governance, the protection, restoration, and enhancement of ecosystem services tend to have multiple benefits (C2.2.3, CF.SDM). It dries out and hardens, making it increasingly difficult for any following rainfall to penetrate below the surface. It is the spread of arid areas caused by a variety of factors, such as climate change (particularly the current global warming) and overexploitation of soil as a result of human activity. Libya is a country that is greatly affected by desertification as the environment is 95% desert or semi desert. 6. It affects a third of the Earth's land, resulting in poverty and hunger for millions of people in dryland environments. Enabling policies that involve local participation and community institutions, improve access to transport and market infrastructures, inform local land managers, and allow land users to innovate are essential to the success of these practices. For example, a key traditional adaptation was transhumance for pastoral communities, which in many dryland locations is no longer possible. In areas where desertification processes are at the early stages or are relatively minor, it is possible to arrest the process and restore key services in the degraded areas. Traveling through Niger, it is almost impossible to imagine that it was once densely wooded . Overfarming or drought can change the soil so that rain no longer penetrates, and the plants lose the water they need to grow. Found insideThe question in the title of this book draws attention to the shortcomings of a concept that has become a political tool of global importance even as the scientific basis for its use grows weaker. I believe that we can reverse the desertification process. Required fields are marked *. That’s the reason why forests and free-standing trees need to be protected in order to prevent spreading of desertification. (NOTE: Statements in this talk have been challenged by scientists working in this field. Further measures like planting of perennial legumes on grazed lands enrich soils of nitrogen and provide additional nutrients for animals. According to the data collected by the China’s forestry administration office, that has been monitoring land cover changes in the country, between 1999 and 2014, areas covered in deserts have decreased [10]. Can Livestock Grazing Stop Desertification? Drawing on cultural history and local knowledge and experience, and reinforced by science, dryland communities are in the best position to devise practices to prevent desertification. Harappan Civilization. Is there a link between desertification, global climate change, and biodiversity loss? Drought can lead to desertification. The following lists potential financial, environmental, and social benefits. Non-desert soil is a mixture of mineral and organic matter. That’s the problem they are facing, but they also have the same ambitious plan how to ward off encroaching sand. Reversing desertification. This means that the degradation is mainly caused by our land use activity, when we alter natural ecosystems and, consequently, rain cycles in arid and semi-arid areas. To be even more specific, in many cases, it is women who perform these tasks. Another popular approach to diversifying farm production is intercropping–when farmers plant two or more crops in one plot. The combination of high variability in ecosystem conditions in drylands and high levels of poverty leads to a situation where societies are vulnerable to a further decline in human well-being. Found inside – Page 398If precipitation increases, then it is expected that vegetation can grow and desertification can be reversed. Consequently, the occurrence of dust storm will reduce. Otherwise, vegetation eventually will die and the region will return ... Throughout the history, sand dunes have always been retreating or slowly expanding into adjacent areas when given the chance. As explained by Savory, water and carbon . Desertification has been described as "the greatest environmental challenge of our time" and climate change is making it worse. "What we're looking at is man-made desertification," said Josh Tickell in his recent keynote speech at Driving Value Through Sustainability Across the Supply Chain. Desertification is a form of land degradation caused by poor land management of dry-lands rather than spreading of existing deserts. It doesn’t matter who shares these memories and from which country that person is, their story is the same. On contrary to other grazing methods, holistic planned grazing is based on the principle of rational grazing, which focuses on carefully planned exposure of plants to grazing rather than limiting the number of animals. Societal and policy responses vary according to the degree of desertification that a society faces.This intensity of responses needs to be reflected accordingly in National Action Programmes stipulated by the UNCCD and their subsequent implementation. In 1994, the United Nations Convention to Combat Desertification (UNCCD) was established in order to manage and develop land that has succumbed to desertification. Sawadogo has revived two traditional farming methods, Zai and cordons pierreux. We must fight back against desertification and reverse its effects while we still can. At Urban Farm U, we believe growing your own food creates a happier, healthier life. They generate relatively high income per land and water unit in some places. Found inside – Page 19They also focus on awareness - raistify measures to prevent and reverse it . ing , education and training , in both developing and develSuccess in combating desertification will require an oped countries . Desertification can only be ... Can desertification be reversed? The good news is that desertification can be prevented. Many organizations, companies, and nonprofits are working on the issue of soil health. This is the first time that a global, baseline status report on land and water resources has been made. Many consider desertification a permanent process that cannot be reversed. Implementation of such practices in drylands requires institution building, access to markets, technology transfer, capital investment, and reorientation of farmers and pastoralists (C22.4.4). All rights reserved. Storm-water ManagementIn a traditional sense storm-water management is a term used by engineers to describe mitigation strategies for controlling nuisance storm-water inundation to major flooding within human settlements. Under these scenarios water is looked at as a problem that could create safety issues for people or cause damage to property. The solution to mitigate these issues is rooted in engineered drainage infrastructure, such as, retention or detention basins, concrete lined channels, culverts, and storm drain systems, which includes storm sewers, manholes, and inlet structures. Living among the dust with diminishing resources? June 15, 2018. For example, scientists have already noticed that trees from the Green Wall in China caused water level decline in the Yellow River—the most important source of water for farmers and communities along its long channel. Several ways that can be used to prevent desertification include the use of significant policy interventions. It consists of placing lines of stones along slopes and contours on the land to help rainfall soak in, and to stop topsoil washing away. Water management - water can be stored in earth dams in the wet season and used to irrigate crops during the dry season. When productive land quickly loses topsoil and plant life, scientists call this desertification. How are desertification and human well-being linked?
