effects of land degradation on human

Land degradation is, usually, the result of complex inter-relationships between biophysical and socio-economic issues which affect many people and their land, specially in the tropics and developing countries. Humans affect biodiversity by their population numbers, use of land, and their lifestyles, causing damage to habitats for species. Soil Density.

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). Over the years, … On human health. Desertification is the persistent degradation of dry land ecosystems by human activities and by climate change. Overgrazing occurs when animals such as cattle, goats, sheep, etc feed on the grass excessively. The interventions are manifold. The 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 … Originally humans lived in the Savanna biomes using its life as a source of food and materials. One of the most serious effects is erosion. [6] Pressure on land India faces the most acute pressure on agricultural land.

The Effect of land degradation on environment Land degradation is an ecological sensation that disturbing arid lands and effect the economic and nature of agronomic lands [5]. Assessing climate and human-induced impacts on land can provide information for decision makers to mitigate the effects of these phenomena. Forest degradation is land degradation that occurs in forest land. g Examples of reasons for degradation in Mediterranean areas. Land degradation also has serious knock-on effects for humans, such as malnutrition, disease, forced migration, cultural damage, and even war. Loss of fertility inland and persistent droughts are some of the contributing factors of several wars happening in Sudan and Syria.

A study by PBL Netherlands Environmental Assessment Agency shows that land restoration has global potential to contribute to multiple sustainability challenges, on food and agriculture, water, biodiversity and climate change. Desertification includes land degradation in arid, semi-arid and dry sub humid areas resulting from various factors, including climatic variations and human activities. Forests cover approximately 30% of the Earth’s land surface and provide critical ecosystem goods and services, including food, fodder, water, shelter, nutrient cycling, and cultural and recreational value. Land and soil degradation undermine the security and development of all countries. In some areas, the natural environment has been exposed to hazardous waste. A large part of these land productivity changes (>61% of the decrease, and >98% of the increase) is directly assigned to human activities, such as native forest growth or tree plantations (for the increase), or forest degradation, deforestation and loss of grassland productivity (for the decrease). Land degradation is often linked to sustainability in terms of keeping its productivity. Land is a vital resource to humankind, like air and water. A large part of these land productivity changes (>61% of the decrease, and >98% of the increase) is directly assigned to human activities, such as native forest growth or tree plantations (for the increase), or forest degradation, deforestation and loss of grassland productivity (for the decrease). Overpopulation has become one of the major environmental issues in the world as it has been damaging the natural environment and increasing pollution. land degradation is a critical global environmental issue. 2. Effects of Nuclear Earth-Penetrator and Other Weapons.Washington, DC: The National Academies Press. It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable. 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—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. Globally, about 24% of the global land area has been affected by degradation and over 1.5 billion people live on degraded lands. Optional work in which respondents are engaged for sustaining livelihoods . Economically, some estimates put the economically loss that land and soil degradation is responsible for at tens of billions of dollars worldwide annually The most obvious effect of overpopulation is the impact on the environment. 2011). Assessing the effects of human-induced land degradation in the former homelands of northern South Africa with a 1 km AVHRR NDVI time-series K.J.

Deforestation is the conversion of forest to non-forest land and can result in land degradation. Effects include land degradation, soil erosion and sterility, and a loss of biodiversity, with huge economic costs for nations where deserts are growing. Land degradation, as a decline in land quality caused by human activities has been a major global issue during the 20th century and will remain on the international agenda in the 21st century. Environmental degradation includes physical effects (such as disfigurement of the land surface), aesthetic degradation effects (such as scenic degradation), and ecological effects (such as disruption of biodiversity and deforestation). Desertification affects as much as one-sixth of the world's population, seventy percent of all drylands, and one-quarter of the total land area of the world. Desertification affects as much as one-sixth of the world's population, seventy percent of all drylands, and one-quarter of the total land area of the world. One negative effect humans have had on Earth is climate change. 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 causes of land degradation can be divided into natural hazards, direct causes, and underlying causes. Such activities are not limited to clearing or removing vegetation striping, but also excavating, filling, and storing materials, e.g., mining. The areal extent of global degraded areas varies depending on the definitions. Forests also store carbon, provide habitat for a wide range of species and help alleviate land degradation and desertification. Human impact on the environment or anthropogenic impact on the environment includes changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans, including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Noise pollution can cause irreparable damage to our ears when exposed to continuous large sounds like honking of vehicles on a busy road or machines producing large noise in a factory or a mill.
