What is rangeland degradation

Degradation and desertification. We define degradation as a decrease in plant species diversity, plant height, vegetation cover and plant productivity.

What causes rangeland degradation?

The proximate causes of rangeland degradation include overgrazing, unsustainable fuel wood (including shrubs) use, mining, and plowing of rangelands with subsequent loss of soil productivity.

What is the cause and effects of rangeland degradation in Ethiopia?

Based on different studies on different rangelands of Ethiopia, the possible causes of rangeland degradation are heavy grazing, recurrent drought, rangeland cultivation, bush encroachment, human population pressures, shortage of rainfall, inappropriate uses of land resources and soil erosion (Teshome et al., 2016).

rangeland, also called Range, any extensive area of land that is occupied by native herbaceous or shrubby vegetation which is grazed by domestic or wild herbivores.

What do you understand land degradation?

Land degradation is the reduction or loss of the biological or economic productivity and complexity of rain—fed cropland, irrigated cropland, or range, pasture, forest or woodlands resulting from natural processes, land uses or other human activities and habitation patterns such as land contamination, soil erosion and …

What are those potential threats to rangelands?

Land degradation, biodiversity loss and climate change are major threats to the rangelands and to the livelihoods of rangeland populations. Rangeland degradation reduces productivity, which weakens livelihood opportunities, increases exposure to risk, and exacerbates poverty.

How is rangeland used?

Globally rangelands are used to raise livestock for food and fiber, harvest renewable and non-renewable energy and mineral resources, provide habitat for wildlife, and open space for human enjoyment and recreation. …

What are the main drivers of rangeland degradation?

Natural causes of rangeland degradation include climate change and variabilities, Photo: CIAT aridity and desertification, drought, as well as alien species invasion.

What are the types of rangeland?

Rangeland is uncultivated land that is suitable for grazing and browsing animals. Rangeland is one of the major types of land in the world. (Other types are: forest, desert, farmland, pasture, and urban/industrial.)

What is the importance of rangeland?

Rangelands may very well represent the last frontier of clean air to breathe and space to play. Rangelands are a natural renewable resource and they can be managed ecologically and be made to remain productive and environmentally stable forever and ever.

What do you mean by land degradation explain the causes of land degradation?

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. Well, it is caused by soil water erosion, wind erosion,loss of nutrients, physical deterioration and salinization.

What are the 5 causes of land degradation?

The major causes of land degradation include, land clearance poor farming practices, overgrazing, inappropriate irrigation, urban sprawl, and commercial development, land pollution including industrial waste and quarrying of stone, sand and minerals.

What is the difference between land degradation and soil degradation?

This definition applies to forest and non-forest land: forest degradation is land degradation that occurs in forest land. Soil degradation refers to a subset of land degradation processes that directly affect soil.

What is range ecosystem?

Rangeland ecosystem services are the benefits that society receives from rangelands. They include the provisioning of food, wood and medicinal resources, and services that contribute to climate stability, control of agricultural pests, and purification of air and water.

How rangelands can be improved?

Strategies such as removal of undesirable plant species (e.g. mechanical, chemical, biological control methods), seeding desirable plants that compete with undesirable species, and using tools such as grazing or prescribed fire as means for restoration.

How do you manage rangelands?

Rangeland management is characterized by extensive, rather than intensive strategies. Foremost among the management strategies for rangelands is grazing management and prescribed fire. Herbicides are used particularly on areas with a history of poor management (i.e., lack of fire and overgrazing).

How important are rangelands to human and wildlife?

Suggested Citation:”1 RANGELANDS ARE IMPORTANT.” National Research Council. … Federal and non-federal rangelands provide grazing areas for wild herbivores such as deer, antelope, and elk. Many species of fish and wildlife depend on rangelands and their associated streams and lakes for habitat.

How much of our rangeland is headed to desertification?

AS much as 85 percent of the rangeland in the Western United States — about 685 million acres — is being turned into desert by overgrazing and other problems, according to a study prepared for the United Nations Environment Program.

Why is desertification bad?

Desertification affects topsoil, groundwater reserves, surface runoff, human, animal, and plant populations. Water scarcity in drylands limits the production of wood, crops, forage, and other services that ecosystems provide to our community.
