Use of satellite imagery has been recommended for monitoring Table 1 provides a summary of previous studies on the cost of salt-induced land degradation. Environmental degradation is a serious problem for humanity. Delaying the implementation of proven actions to combat land degradation will result in the necessary steps becoming progressively more difficult and costly. Table 1. Thus, the rehabilitation of degraded lands is critical. Severe land damage accompanies large-scale of agriculture. Nevertheless, in the search for sustainable global futures, land degradation has once again come to the fore. These biosurfactants are also involved in biofilm formation and can also interact with various microbial proteins. Land degradation is the blanket term usually used to describe a number of land and soil degradation issues Land and soil degradation can take many forms - up to 36 of degradation types exist Each origin and flow pathway has different implications for water quality with respect to solute and sediment load, and the manifestation of erosion, waterlogging, or soil salinity. These include pressure on land, land/soil degradation, forests, habitat destruction and loss of biodiversity, changing consumption pattern, rising demand for energy, air pollution, global warming and climate change and water scarcity and water pollution. However, although the information generated has been technically sound, 2015).In spite of this, land degradation has become a global problem occurring in most terrestrial biomes and agro-ecologies, in both low income and highly industrialized countries (Le et al. Using these two data sets, Crosson calculated the weighted average cumulative loss on the 8.7 billion hectares of land in crops, permanent pasture, and forest and woodland to be 4.6% (slightly less than 0.1 percent annually over the 45 years to 1990). Plant-based biosurfactants have excellent emulsification properties, although they are expensive to produce on an industrial scale. 5 1. Understanding the complexity of the numerous and interacting socioeconomic and biophysical causal factors underlying land degradation and the problems of modern agriculture in the tropics and subtropics is difficult. pressure has increased land degradation, primarily through deforestation. Current estimates are that land degradation affects 2 billion hectares (38% of world cropping area) (Eswaran et al., 2006), with soil erosion affecting 83% of the global degraded area (Bai et al., 2008). Opinions about the causes of land degradation and desertification, but especially about the solutions, are very divided. in the 1990s. Executive Summary The implementation of the Land Degradation Neutrality (LDN) pilot project in Namibia by the Ministry of Environment and Tourism (MET) has been accomplished through support from the Deutsche 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. This, in turn, suggests that the GR technologies adopted by farmers around the world since the end of World War II have not significantly damaged the capacity of the Earth's land to support global agricultural production.

Essay # 1. able land management, the op12 funding window was used by many countries in which land degradation— specifically desertification and deforestation—was considered a major threat to the global environment. Land and soil degradation can harm many plants. Sustainable ways to reduce land degradation and desertification demand research and advocacy of sustainable land management practices. This book is organized into two sections. The speech was a response to the treaty of the American Government for buying the land of native Americans. If the average yield of cereals is 2 t/ha, the total production of cereals on non-degraded land would be 1 000 000 tons, but since strong degradation causes a reduction of 75% of production, the total production on degraded land will be only 250 000 tons (i.e. Increased land degradation around a watering point on Dia islet (Crete) (photo by V. Papanastasis). managing fallow period and intensification of land use. Biosurfactants may also contribute to agricultural sustainability by acting as antimicrobial agents for disease control. This led to the more holistic concept of ‘land husbandry,’ including all farm-level production activities, argued as being a more effective tool for delivering conservation than technical, often structural, measures such as earth bunds (contour embankments to intercept runoff and sediment). agricultural practices (Boyd and Slaymaker, 2000; Carr, 2003; Nyangena and Sterner, 2008*).

Land degradation From Wikipedia, the free encyclopedia Serious land degradation in Nauru after the depletion of the phosphate cover through mining Land degradation is a concept in which the value of the biophysical environment is affected by one or more combination of human-induced processes acting upon the land. For example, the origin, quantity, and quality of water persisting at the soil surface can result from runoff, interflow, and return flow from the soil, high water table, high groundwater pressure, or a combination of these. Desertification is defined by the U.N. Convention to Combat Desertification as "land degradation in arid, semiarid and dry subhumid areas resulting from various factors, including climatic variations and human activities." Land degradation is in turn defined as the reduction or loss of the biological or economic productivity of drylands.

Conclusion. Land degradation can therefore be defined as the misuse of land or the deterioration in the quality of the land through excessive exploitation of the land. The problems are especially severe in Africa, where more than 80% of countries are nitrogen-deficient, and where nutrient loss has been estimated at 9–58 kg ha−1 year−1 in the 28 worst affected countries and 61–88 kg ha−1 year−1 in 21 others (Chianu et al., 2012). support of public institutions and sufficient cohesion of local communities, especially a strong Misdiagnosis can readily lead to prescription of costly and ineffective solutions. This book offers the scientific basis for the ample evaluation of badland management in India and some surrounding regions. (1991) at Wageningen University in the Netherlands is dated but still instructive. In this highly interactive cycle, a desire for security and wealth drives deforestation, overgrazing, and unsustainable use of soils and water, all of which cause agroecosystem degradation.

This leads to what is called the yield gap in food crops, which is the difference between the yield potential of new modern varieties and the yield actually achieved by a farmer (Tittonell and Giller, 2013). Land degradation is a global phenomenon that affects human societies at the local level where rural communities closely related to land resources are vulnerable. PART 2 APPENDICES Crosson (1995) did this by combining the data compiled at Wageningen with data from another global-scale study done by Harold Dregne and Nan-Ting Chou (1992) at Texas Tech University. Ecological restoration is identified as one of several key activities that can reverse this trend (MEA, 2005a). Jock R. Anderson, in Encyclopedia of Food Security and Sustainability, 2019. land. Éder de Vilhena Araújo, ... Taicia Pacheco Fill, in Microbial Endophytes, 2020. Land degradation in Sub-Saharan Africa remains a substantial problem in aggravating poverty, by reducing the availability of environmental goods and services to poor rural households and by increasing the labor time needed to seek for such goods. Soil fertility depletion, land degradation, desertification, and deforestation are known to be the root causes of food insecurity, malnutrition, and poverty in sub-Sahara Africa. This paper examines ants and their importance in ecosystem functioning, principally their ability to maintain or restore soil quality in rural environments, and their value as bioindicators of soil quality. Likewise, The study showed that about 2 billion ha of this land (23%) has been degraded to some extent (slightly, moderately, and strongly) in the period since the end of World War II to 1990. This provides an entry point for land degradation neutrality in Kenya which aims to stop, reduce and avoid further degradation.

"Local Perception of Land Degradation in Developing For vegetation, important indicators are the amount of biomass produced or left at the end of the grazing period, the plant cover (Papanastasis et al., 2003) and the species composition. The 1992 United Nations Conference on Environment and Development in Rio de Janeiro revived interest. Reactive oxygen species scavengers such as ascorbate, glutathione, and tocopherol act as antioxidants (Rouhier et al., 2008). In turn, farmers’ goals are defined by the Field research stations report soil losses 35 to 246 tons ha/yr, and farmers report declining Summary Desertification can be considered to be a subset of land degradation, occurring in more arid areas; though land degradation is usually defined as being caused by human actions. are in shrub land/grasslands; 4.4 M ha are in the crop land category and 169,276 are in wetlands. L.A. Lobry de Bruyn, in Invertebrate Biodiversity as Bioindicators of Sustainable Landscapes, 1999. 1.6 Discussion: Data and evidence for land degradation 34. Today, the fastest-growing section of the global funding mechanism (the Global Environment Facility, GEF), which supports the incremental cost of developing countries' efforts to comply with the international environment-development conventions, is for land degradation projects. mitigation. Eighty-four percent of this land had been degraded by wind and water erosion. The net result highlighted by this conceptual cycle of land degradation and social deprivation is that in developing countries where farmers are poor and must rely on a small piece of land for all their household needs, the benefits expected from existing agricultural technologies, such as improved crop varieties and livestock breeds, are constrained by a need for income to purchase the inputs essential for food production. 5 1. More recently (2000s), satellite-based imagery and remote sensing have been utilized to identify the magnitude and processes of land degradation at global, regional and national .

It is recognized that at all of the steps within this conceptual diagram, there are a range of socioeconomic and biophysical influences that will determine the speed of the downward progress at any particular site. Land degradation is defined as the temporary or permanent decline in the productive capacity of the land, and the diminution of the productive potential, including its major land uses (e.g., rain-fed arable, irrigation, forests), its farming systems (e.g., smallholder subsistence), and its value as an economic resource. The scenarios for irrigated land are based on the trend predicted for 1990-2010, with a slowly decreasing growth rate in the course of time. It is becoming increasingly evident that allowing the land to degrade is expensive both for the local owners and land users and the society and communities not only in the short term but also in the longer term (Costanza et al., 1997). order to insure short-term economic benefits. mitigating damage at the local level depends on the approach adopted. The causes of land degradation include the deforestation, cropland agriculture and overgrazing and it affects up to 1/3 of the world's people.
