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 caused by deforestation, overgrazing, and inappropriate irrigation practices affects about 16% of Latin America and the Caribbean (LAC). © 2008-2021 ResearchGate GmbH.

Combined use of morphometric and physical techniques made it possible to explore the they enhanced the availability of nutrients to the plants. desertification. “Desertification and land degradation are major threats to agricultural productivity in our country. Land degradation means: 1. dynamic flow behaviour in these complex soils. Agriculture directly depends on the broader environment and uses about a 3rd of the world's land surface. solutions. Less vegetation cover Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. 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. Land Degradation & Development Edited By: Chris Barrow, Martin Brandt, Jan Frouz, Vanessa Wong, Yakov Kuzyakov, Gerardo Ojeda and Jan Nyssen Impact factor: 3.775 The recent food crises were not accidents and they are not over. Access scientific knowledge from anywhere. And as fertile soil washes away, agricultural producers move on, clearing more forest and continuing the cycle of soil loss. A major hazard of deterioration of structural In recent years, over-water pumping of underground aquifers, has led to land subsidence, especially in arid and semi-arid regions. capita agricultural land, forest and water resources. (hydrology) Lowering of a stream bed. Due to rapid changes in climatic conditions, deforestation, desertification, erosion, salinization, waterlogging, and organic matter depletion lead to land degradation. It signifies a regression from a higher to lower state, owing to descend in land capability, productivity, and decline of biodiversity. Land degradation and desertification are among the big environmental issues in India. Moreover, the partial or total occlusion of the (macro) pores in the micro-sprinkler irrigated field. 2013. There is loss of not only water and plant nutrients but ultimately soil itself is lost, which, in turn, affects crop productivity. Thus, land degradation more than climate change is likely to pose significant challenges for overall wheat production in the future. Moreover, variables like trade, industry and agriculture have positive relation with GDP growth rate. Land degradation affects 1, 5 billion people globally. The world population is projected to increase by about 35 percent to 9.7 billion in 2050, with rising demands for agricultural products including food, feed, fiber, and fuel. is causing land degradation and reduces the microbial population which ultimately negatively affect the plant growth. Agricultural land is necessary component for food production, shelter and fiber for mankind, Book details Roy H. Behnke and Michael Mortimore (editors) The End of Desertification. The relevance of bypass flow on the water balance in a Mediterranean climatic context as Fig. It aims to support investment in SLM by the Global Environment Facility (GEF), particularly investments in pursuit of Land Degradation Neutrality. Degrading the buffer zone of the drylands increases drylands' vulnerability to degradation. Salinization is closely associated with the process of desertification. and hydraulic properties was recognized even at low ESP values (ESP<5) in dilute The analysis reveals that outcomes of high population growth rates are increasing population density and number of people below poverty line. In this study, we have analyzed the role of agriculture sector share in Gross Domestic Product (GDP) of Pakistan economy by using time series data from 1975-2012. Global Land Degradation: . In Burkina Faso, several multilateral partners financed the Sustainable Rural Development Program implemented by IFAD in the North Central Plateau. Whilst soil degradation is recognised as a major aspect of land degradation, other processes which affect the productive capacity of cropland, rangeland and forests, such as lowering of the water table and deforestation, are captured by the concept of land degradation. This form of study reports the potential physical effects of environmental change on agriculture. ► Current degradation assessments and impact give divergent and unverified outcomes. showed that bypass flow corresponded with about 70-74% of cumulative yearly rainfall, Our investments to arrest and reverse desertification and deforestation cover a wide range sectors — from crop and livestock production to water resource management. Microbes Land degradation is caused by multiple forces, including extreme weather conditions, particularly drought. 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. decreasing all over the world. These exchanges were effective in And as fertile soil washes away, agricultural producers move on, clearing more forest and continuing the cycle of soil loss. Land degradation stretches to about 30 % of the total global land area and about three billion people reside in degraded lands. In terms of outcomes, the land related conflicts significantly decreased, 109 cases of access to land, services, and infrastructures were solved, and 26,000 producers were given sustainable access to land for cultivation and market gardens, 67% of beneficiaries being women. Some major factors like … ► Process-based approaches can link degradation and impact at different levels. (geology) The wearing down of the land surface by processes of erosion and weathering. crop evapotranspiration and underestimation of the hazard of land degradation and alternated use of a high salinity solution to distilled water showed that exchange of solutes The condition of the soil is one of the best indicators of land degradation. regarding their importance, people think about the negative impact of microorganisms because in many cases microbes Since 2006, when land degradation became a focal area, the GEF has invested more than $1.069 billion in resources for at least 190 projects and programs that encourage use of sustainable land management practices (SLM) to support national and regional development priorities. When land is degraded, soil carbon and nitrous oxide is released into the atmosphere, making land degradation one of the most important contributors to climate change. and land degradation are also occurring. Globally, about 25 percent of the total land area has been degraded. Climatic change affects agriculture by emissions of greenhouse gases such as nitrous oxide, methane and carbon dioxide. There are many ways to mitigate drought under field conditions but the best and the easiest method is foliar application. Land is a vital resource to humankind, like air and water. Land degradation is one of the world’s most pressing environmental problems and it will worsen without rapid remedial action. effect of irrigation on soil structure and bypass flow phenomena of a Sicilian cracking soil 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. Land degradation which is also seen as a decline in land quality caused by human activities, has been a major global issue since the 20th century and it has remained high on the international agenda in the 21st century. The land degradation assessment is the latest in a recent suite of global studies that highlight the deterioration of humanity’s home. Environment is the primary determinant for the productivity of agriculture. Land degradation is, however, difficult to grasp in its totality. Land degradation is defined as a process of human-induced activity that results in undesirable changes or disturbances to land, resulting in permanent or temporary decline in the productive capacity of land and reduction in ecosystem goods and services (Arthur and Jeannett, Reference Arthur and Jeanette1995; FAO, 2000). The coverage of the subject is global, but much of this, particularly deforestation and desertification, is concentrated in Third World countries. 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. In recent decades there have been numerous global and regional targets and initiatives to halt and reverse land degradation. It is estimated that nearly 2 billion ha of soil resources in the world have been degraded, namely approximately 22% of the total cropland, pasture, forest, and woodland. Desertification includes land degradation in arid, semi-arid and dry sub humid areas resulting from various factors, including climatic variations and human activities. If this trend continues, 95 percent of the Earth’s land areas could become degraded by 2050. Soil erosion is one of the most destructive phenomena of land degradation. It negatively affects food production, livelihoods, and the production and provision of other ecosystem goods and services. The direct sources of these emissions are use of tillage practices, fossil fuels, manuring of livestock and use of fertilized agricultural soils in large proportion. In agriculture we can find a huge amount of literature regarding environmental management and adoption of technology for sustainable farming. This two-way relation among environmental change and agriculture is gaining great importance. processes was recognized on the basis of hydraulic conductivity values determined by the Typically, one gram of soil having more than 90 million bacteria The results of the study showed positive and significant relation between the GDP and agriculture in Pakistan. It poses a serious threat to biodiversity loss [ 3 ], food and energy security [ 4 ], land desertification [ 5, 6 ], sustainable socio-economic system development and human living environments [ 7 ]. Soil provides base for agriculture crop production and microbial activity is very important to improve soil health for Land degradation is one of the world’s most pressing environmental problems and it will worsen without rapid remedial action. Land degradation is a widespread global problem, particularly severe in the developing countries, which has led to the valid concerns about food security and environmental quality (Bhattacharyya et al., 2015; Gomiero, 2016). The three GEF Impact Programs form a major component of the GEF delivery towards combating land degradation and deforestation. The GEF is well-placed to help countries implement convention decisions and facilitate coordinated investments in sustainable land management practices, including LDN.
