The report explores the anthropogenic and natural drivers of land degradation, and the potential environmental and socioeconomic benefits of SLM; examines the role of SLM in addressing the critical challenge of global food security; describes the key processes of land degradation and their impacts, as the basis for developing good practice guidance on SLM that is scientifically sound and robust; The GEF is the financial mechanism for the United Nations Convention to Combat Desertification (UNCCD), and has a mandate to invest in global environmental benefits from production landscapes. The journal focuses on: 1. what land degradation is; 2. what causes land degradation; 3. the impacts of land degradation 4. the scale of land degradation; 5. the history, current status or future trends of land degradation; 6. avoida… In agriculture we can find a huge amount of literature regarding environmental management and adoption of technology for sustainable farming. The 2017 Future Policy Award (FPA) identifies and honors policies and laws around the world that are effectively combating desertification and land degradation. Zinc is a vital element that plays an important role in many biological processes. The coverage of the subject is global, but much of this, particularly deforestation and desertification, is concentrated in Third World countries. Land degradation is the human-induced loss of biodiversity, productivity, and ecosystem functions from terrestrial and aquatic environments. The two ends converge to give a zero-net rate of land degradation. ISBN 978-3-642-16013-4. ► Location specific interventions are essential to mitigate and rehabilitate degradation. In recent years, over-water pumping of underground aquifers, has led to land subsidence, especially in arid and semi-arid regions. No bypass flow or lower amounts ofbypass flow were observed in the micro-sprinkler irrigated field compared to the drip It negatively affects plant mechanisms such as formation of proteins, nucleic acid, lipids and carbohydrates which reduces the final crop growth and production. This is considered to … The analysis reveals that outcomes of high population growth rates are increasing population density and number of people below poverty line. Soil erosion is one of the most destructive phenomena of land degradation. Loss of natural fertility of soil because of loss of nutrients. The major causes of land degradation in Ethiopia are the rapid population increase, severe soil loss, deforestation, low vegetative cover and unbalanced crop and livestock production. Due to lack of knowledge Land degradation effects on a global scale 2.6 billion people depend directly on agriculture, but 52% of the land used for agriculture is moderately or severely affected by soil degradation. It is non-renewable resource which is degraded day by day. 143 million hectares are now under SLM, benefitting more than 80 million smallholders. they enhanced the availability of nutrients to the plants. -J.W.Cooper. Other hand land degradation is a continuing deterioration of environment and production. GEF will also make targeted investments to sustain and rebuild productive areas, mitigate the effects of drought, increase resilience, and prevent conflict and migration. Land degradation can also be caused by activities such as the quarrying of stone, ore, etc and the indiscriminate disposal of plastics and other material that are non-biodegradable. saline/sodic waters are increasingly used in many arid and semi-arid regions of the world. Land degradation—the deterioration or loss of the productive capacity of the soils for present and future—is a global challenge that affects everyone through food insecurity, higher food prices, climate change, environmental hazards, and the loss of biodiversity and ecosystem services. However, according to the agricultural point of view microbes are very well beneficial for helps in different biological transformation such as organic matter conversion and biological nitrogen fixation. This paper addresses issues related to the application of remote sensing technologies for the identification and mapping of land degradation features, with special attention to the LAC region. help plants in nutrient uptake by conversion of unavailable nutrients into available form. The report is intended to provide information and guidance on fostering SLM, to a wide range of stakeholders involved in agriculture, environmental management and sustainable development. 2. drip and micro-sprinkler. Amongst various sources of land degradation the highest share is of desertification which is about 2.6 billions ha, followed by about 2.0 billion ha by soil degradation and 0.5 billion ha from deforestation. The three GEF Impact Programs form a major component of the GEF delivery towards combating land degradation and deforestation. Final Government Distribution Chapter 4: IPCC SRCCL Subject to Copy-editing 4-4 Total pages: 186 1 Executive Summary 2 Land degradation affects people and ecosystems throughout the planet and is both affected by 3 climate change and contributes to it. Dryland landscapes cover approximately 40 percent of the world’s land area and support two billion people. For this purpose the study considered several variables such as agriculture, industry, trade and GDP of Pakistan. Agriculture directly depends on the broader environment and uses about a 3rd of the world's land surface. It is also caused by human activities that pollute or degrade the quality of soils and land utility. (hydrology) Lowering of a stream bed. The Food Systems, Land Use, and Restoration (FOLUR) Impact Program provides the opportunity for an integrated approach to implementing sustainable land management to increase the prospects for food security for smallholders and communities that are dependent on farming for their livelihoods. This paper makes an attempt to study the various causes of land degradation and its ways to overcome it and also aims at creating awareness among different sections of people. Population pressure contributes to land degradation and soil erosion, thus affecting productive resource base of the economy. Essentially, LDN is about managing land more sustainably to reduce degradation, while increasing rates of land restoration. Globally, about 25 percent of the total land area has been degraded. The demand for productive land is high and competition over various land uses is intense.
