2008). It is clear that the impact of land degradation is a drain on economic growth in Typology of Global Impacts of Land Degradation Global impacts of land degradation can be classified in several ways, by the environmental system affected; by impact on ecosystem service; by type of LD process; by production system/eco-region impacted on or by type of management practice that causes the degradation. Resilience of Landlocked Developing Countries to the Impacts of Climate Change, Desertification, Land Degradation and Drought that was held on 18 These in - Soil degradation refers to negative changes in the physical, chemical, and biological properties of the soil, whereas vegetation degradation is the reduction in the number of species and the vegetational composition. Definition. Soil is a complex body and forms the thin outer layer of the earth. The immediate impact of land degradation is on soil productivity leading to impacts on peoples welfare. It takes many forms, It blights a significant proportion of the land surface, and as much as one-third (1/3) of the worlds population suffer disproportionately from its effects (Dogo, 2014). Land is a vital resource to humankind, like air and water. Usually land degrad ation is described in terms of the loss A temporary or permanent decline in the productive capacity of the land. The impacts of land degradation include a reduction in crop and pasture productivity and fuel wood and non-timber forest products, which are closely linked to poverty and food insecurity. Land degradation is a decline of the economic and biological productivity of land because of human treatment. Various scientific methodologies have been employed to assess land degradation globally. Land degradation means:Loss of natural fertility of soil because of loss of nutrients.Less vegetation cover ADVERTISEMENTS:Changes in the characteristic of soil.Pollution of water resources from the contamination of soil through which water sweeps into ground or runoff to the water bodies.Changes in climatic conditions because of unbalanced created in the environment.

Andersonb, Robert Costanzac, Ida Kubiszewskic a Department of Geography and the Environment, University of Denver, United States b School of Natural and Built Environments, University of South Australia, Australia c Crawford School of Public Policy, The Stocking and Murnaghan (2001) indicate that land degradation includes all productivity-reducing effects that are due to inappropriate use, implying that degradation is a result of human activities. Land degradation has multidimensional effects on the biodiversity of the earth and the global economy. The resultant ecological impacts of land degradation in Ethiopia include loss in the chemical, physical and/or i t also negatively affects the worlds ability Download PDF. These effects are far-reaching with off- site costs (referred to in Chapter 2) extending well beyond the site where land degradation has occurred. MATERIALS AND METHODS Study Area little attention to socio-economic factors that affect the land conservation efforts (Buyinza et al. Land degradation has many negative impacts on agriculture and environment. Download File PDF Land Degradation In Ethiopia Causes Impacts And analyze the patterns, driving factors and proximate causes, and the socioeconomic impacts of soil degradation. Socio-economic impact Land degradation Human-made conditions g. y g. ernance e cacy. Soil degradation through erosion, nutrient loss results in undesirable physico-chemical soil properties and there by considerably depresses crop yield. This obviously leads to land degradation. For example, South Africa has made provisions to avoid, reduce and reverse land degradation by being a signatory to several multilateral climate and environmental agreements. Degraded lands are more susceptible to the adverse effects of climatic change such as increased tem- 19 It includes soil degradation, human impact on water resources, deforestation and the decline of rangelands used for grazing. Forest degradation occurs when the ecosystem functions of the forest are degraded but where the area remains forested rather cleared (Anon., 2010). INTRODUCTION Forests and the benefits they provide in the form of wood, food, income, and watershed protection have an important and critical role in enabling people to secure a stable and adequate This paper is based on the study carried out in Mt. 2009). Degraded lands are more susceptible to the adverse effects of climatic change such as increased tem- It was estimated that the original forest cover was approximately six billion hectares (Bryant et 19 It includes soil degradation, human impact on water resources, deforestation and the decline of rangelands used for grazing.

Land Degradation: 9 Main Causes of Land Degradation The major causes of land use and cover change (LUCC) and land degradation in the area were population Steps to prevent land degradation through existing environmen - tal agreements often provide significant scope for action to reduce land degradation. Land degradation has negative consequences on agriculture. Review Article; Published: 13 November 2018; Land degradation and poverty. land degradation related to vegetation and biodiversity. 32% of total geographical area in India (Table 1 and Figure 1) is affected by desertification and land degradation processes (SAC, 2016). 2. In addition, land degradation directly affected the type of plant grown on the area, reduced availability of potable water, lessened volumes of surface water, depletion of aquifers and biodiversity loss. The rate of degradation has increased dramatically with growth in human populations and technology. The term land degradation involves both soil and vegetation degradation. i t directly affects the livelihoods of millions of people, many of them poor and vulnerable in the worlds drylands, where more than 500 million hectares of land is degraded. The soil finds its way into beds of streams and rivers, thus reducing their capacity to contain water which causes floods. The combined reclassification is shown in the following map and table (Figures 4 and 5). Land degradation is the process of deterioration of soil or loss of fertility of soil. Land degradation is a great threat for the future and it requires great effort and resources to ameliorate. The paper addresses the hypothesis that, in Tanzania, impacts of land degradation can be reduced through the application of incentive market based mechanisms that could be implemented by the land users to ensure dual benefits i.e. The conversion of land to other progress reduces the amount of land of open spaces and environmental facilities for residents. The degradation also impacts our wildlife, plants, animals and micro-organisms. This severely constrains the scientific knowledge which WG 1 can synthesize and evaluate. this review paper was to assess concepts of rangeland degradation by giving due emphasis to Yabello rangelands from data available from different studies, to know major causes of rangeland degradation and its impact and to identify and recommend the most appropriate methods used for rehabilitation of the Yabello degraded range lands. That research considered three aspects of land use changes: economic, social and environmental. Soil Degradation Ann Verdoodt Academic Year 2011-2012 Compilation of course notes by Prof. Donald Gabrils and new materials by Prof. Ann Verdoodt IFPRIs IMPACT model is a partial-equilibrium simulation model that determines supply, demand, and prices in a competitive market for 16 crop and livestock commodi-ties in 36 countries and regions as functions of specified initial conditions (Rosegrant et al., 2001). land and securing it from further degradation, we cannot save the land from the impacts of climate change, replenish underground sources to meet present and future water demands, diffuse ethnic tensions or reverse migration flows. This chapter first considers briefly the history of land degradation with some comparisons between the old and new worlds and consideration of the data or evidence. Recently India published report cum Atlas on land degradation and desertification mapping of India which shows 29. 20 Each year this degradation costs the world 6.3 17 Policy Impacts on Land Degradation 221 and locally some pieces of cropland, and thus named the Mu Us Sandy Land.The eld investigations by Huang and Zhang (2006) identied as the main herbaceous and shrub species in this sandy land Artemisia ordosica, Stipa bungeana, Juniperus vulgaris, and Caragana intermedia. Over 1 billion people today have no access to water, and demand will increase by 30% by 2030 The ecological economics of land degradation: Impacts on ecosystem service values Paul C.

Similarly, during the Gadaa of Guyyoo Gobbaa (20082016), the loss of palatable species (96.08%), bush encroachment impacts of land degradation and which are those? {4.1.6, 4.2.1, 4.2.3, 4.3, 4.6.1, 4.7, Table 4.1} Climate change exacerbates the 1. Often land degradation is perceived as having only negative effects for land users and society alike. Land degradation affects Ethiopian economy and also has many negative impacts on agricultural productivity by reducing the fertility of agricultural land. The paper addresses the hypothesis that, in Tanzania, impacts of land degradation can be reduced through the application of incentive market based mechanisms that could be implemented by the land users to ensure dual benefits i.e. "hotspots" ofland degradation and "brightspots" of land improvement, and recommended policy action to reduce degradation and promote land improvement. 1.1 Impact of land degradation on productivity Land degradation is here defined as the decline in biophysical functions of a tract of land. Land degradation is a decline of the economic and biological productivity of land because of human treatment. Elgon catchment aimed at making an assessment of the socioeconomic impact of land degradation in the mid-hills of Mt. The resources which are affected include water, air and soil. Elgon catchment aimed at making an assessment of the socioeconomic impact of land degradation in the mid-hills of Mt. This paper assesses the harm that human-induced land degradation poses on terrestrial ecosystems. Land degradation is caused by human activities and natural processes and is little attention to socio-economic factors that affect the land conservation efforts (Buyinza et al. Key b. Soil erosion and land degradation through various means further affect the physical viability of the soil profile and the environment in terms of solid, water, air ratio as well as chemical and biological balances. These, in turn diminish the availability of nutrients and water to the plants and ultimately the productivity of the land. The damage to soil, loss of habitat, water shortages, and Download Free PDF Download PDF Download Free PDF View PDF. Now let us briefly study about both of these. It is the process of human-beings affecting the atmosphere. Year 10 Geography S1 Land Degradation Todays task is to read Chapter 11.2 The Causes and impacts of An effort to curb natural resources degradation, particularly land degradation in farmland and communal grazing land and thus improve rural livelihood has been attempted by the Ethiopia government in partnership with sustainable land management project in Zeiy watershed in Godere district of Majang zone, Gambela region. Degradation impacts are visible on more than 90% of the arable land in the country. The UN Convention to Combat Deserti cation (CCD), of which Kenya is a signatory, recognizes land degradation as a global development and environment issue. Very often [] LDNwith conservation, sustainable use, and restoration as its three pillarsprovides an effective framework. Demand is What is Land Degradation Burning Issues Free PDF Download. The land degradation issue for world food security and Land degradation classes Biophysical land degradation classes are identified by the combination of the overall status in provisioning biophysical ecosystem services and the trend of these services (Biomass, Soil, Water and Biodiversity) as described above. The effects of land degradation may be experienced by future generations, affecting how they can use the land. The huge population of livestock needs to be fed and the grazing lands or pasture areas are not adequate. 2. Land degradation is the reduction of the useful qualities and productiveness of soil because of the natural and anthropogenic factors. Desertification, a phenomenon referring to land degradation in arid, semi-arid and dry sub-humid regions as a result of climatic variations and human activities, is considered as one of the most severe environmental and socio-economic problems of recent times. Land degradationthe deterioration or loss of the productive capacity of the soils for present and futureis a global challenge that affects everyone through food insecurity, higher food prices, climate change, environmental hazards, and the loss of biodiversity and ecosystem services. There is loss of not only water and plant nutrients but ultimately soil itself is lost, which, in turn, affects crop productivity. Elgon catchment area. environmental impacts of land degradation include a rapid loss of habitat and biodiversity, modifications of water flows, and sedimentation of reservoirs and coastal zones (Project Development Facility 2007). Land degradation is not only the erosion of soil but also the alteration of the lands surface because of the impact of water, wind and human activity. Land degradation processes are on-going over large part of the Earth land surface (Figure 3). Climate Change and Land Climate change exacerbates land degradation Land degradation is a driver of climate change through emissions of GHGs and reduced uptake of carbon Gross emissions from Agriculture, Forestry and Other Land Use make up 1/3 of total global emissions Land accounts for 61% of anthropogenic methane emissions. The agricultural impacts of land degradation are, loss of soil nutrient, Soil erosion effects, reduction of crop yield, silting up of reservoir and It 1.1 Impact of land degradation on productivity Land degradation is here defined as the decline in biophysical functions of a tract of land. effect is severe if it Land degradation may be caused by i.e. This study therefore seeks to identify the main impact of land degradation on livelihoods of the study area in direct and Combating desertification and land degradation and mitigating the effects of drought will secure long-term socio-economic benefits for people living in the drylands and reduce their vulnerability to climate change. impacts of land degradation and a good assessment base of the proximate and root causes. Evaluation of grazing impacts on land degradation processes is a difficult task due to the heterogeneity and complex interacting factors involved. Land degradation is the result of complex interaction among, physical, chemical, biological, socio-economic and political issues of local, national or global nature. CISL Research Webinar Series: Led by the Prince of Wales Fellows, this series of one-hour webinars allowed attendees to engage directly with our Fellows about their research. The most important factors reducing soil productivity by soil The causes of land degradation can be divided into natural hazards, direct causes, and underlying causes. There is massive land disturbance due to use of land for large scale excavation ,dumping of overburden, making industrial and service building ,roads and other infrastructure , township etc. Chapter 2 summa rizes perspectives on the global trends and effects of land degradation. However, The soil finds its way into beds of streams and rivers, thus reducing their capacity to contain water which causes floods. It was estimated that the original forest cover was approximately six billion hectares (Bryant et We propose and define a hazardous impact (HI) indicator and a method to quantify this degradation and promote sustainable land use under the pressure resulting from population growth. 20 Each year this degradation costs the world 6.3 In 2008, another related research has conducted on impacts of land uses changes. Land degradation occurs slowly and cumulatively and has long lasting impacts on rural people who become increasing vulnerable (Muchena 2008). Soil erosion is one of the most destructive phenomena of land degradation. The Prince of Wales Global Sustainability Fellowship in Nutrition in the first 1000 days of life, supported by Brighter Living Foundation. Land degradation refers to any diminishment of biodiversity and ecosystem functioning that negatively impacts the provisioning of ecosystem services and ultimately impedes poverty eradication and sustainable development. 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. Land degradation resulting from various natural and anthropogenic activities including the loss of organic matter, decline in soil fertility, erosion, and the effects of toxic chemicals is a serious global environmental problem and it may be triggered by climate change (DeFries et al., 2012; Lal, 1997). Thirty per cent of the earth s land area or abou t 3.9 billion hectares is covered by forests. environmental sustainability and improved human welfare of the land users. Key Research into the nature, extent and causes of land degradation is then reviewed; it is necessary to understand the There is much less information on the impact on the ground of these actions. water erosion, deforestation, soil compaction, desertification, salinization, waterlogging and many more.
