The land degradations can be controlled by management of
deforestation, manag-ing irrigation, managing urban sprawl, managing min-ing and quarrying
, managing agricultural intensifica-tion and land reclamation.
What are the 5 causes of land degradation?
- Deforestation: Forests play an important role in maintaining fertility of soil by shedding their leaves which contain many nutrients. …
- Excessive Use of Fertilizers and Pesticides: …
- Overgrazing: …
- Salination: …
- Water-logging: …
- Desertification: …
- Soil erosion: …
- Wasteland:
How can we prevent land degradation?
- Curb industrial farming. Tilling, multiple harvests and agrochemicals have boosted yields at the expense of sustainability. …
- Bring back the trees. Without plant and tree cover, erosion happens much more easily. …
- Stop or limit ploughing. …
- Replace goodness. …
- Leave land alone.
What are the main 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 are the causes of land degradation How can it be controlled?
- By restoring forests and grass cover, soil erosion and flood can be checked. …
- Shifting cultivation can be replaced by crop rotation practices. …
- Adequate drainage should be made to prevent salinity of soil.
What is land degradation and what are its major causes?
Land degradation is caused by multiple forces, including
extreme weather conditions, particularly drought
. It is also caused by human activities that pollute or degrade the quality of soils and land utility. … Desertification is a form of land degradation by which fertile land becomes desert.
What are the causes and effects of land degradation?
The two most significant direct causes of land degradation are
the conversion of native vegetation into crop and grazing lands, and unsustainable land-management practices
. Other factors include the effects of climate change and loss of land to urbanisation, infrastructure and mining.
Which two factors are responsible for land degradation?
Solution:
Deforestation and the indiscriminate use of chemical pesticides and fertilisers in agricultural lands
are two factors contributing to land degradation.
What is an example of land degradation?
Land degradation occurs when the economic and biological productivity of land is lost, primarily through human activities. This can happen, for example, when:
Fertile soils erode away
, … Soils are degraded by acid pollution and heavy metal contamination.
What is land degradation in simple words?
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 is the problem of land degradation?
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
.
Why land is considered an important resource?
(iii) Why is land considered an important resource? Answer: Land is considered an important resource
because it can be put to use for various purposes like agriculture, forestry, mining, building houses, roads and setting up of industries
.
What are the effects of degradation?
The effects of soil erosion go beyond the loss of fertile land. It has led to
increased pollution and sedimentation in streams and rivers
, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
Why is it important to protect land from degradation?
In all countries where the degradation problem is a threat,
land conservation efforts need to be increased
. … Furthermore, managing and mitigating land degradation can also contribute to protecting soil biodiversity and carbon stocks in terrestrial ecosystems for sustainable agriculture, health and life.
Which is a natural factor for land degradation?
Taking the form of desertification, deforestation, overgrazing, salinization, or soil erosion, land degradation can be caused by biophysical factors, such
as the natural topography of an area or its rainfall, wind, and temperature
; and unsustainable land management practices, such as deforestation, soil nutrient mining …
What are the factors that are responsible for environmental degradation?
Environmental degradation is a result of the dynamic inter play of socio-economic, institutional and technological activities. Environmental changes may be driven by many factors including
economic growth, population growth, urbanization, intensification of agriculture, rising energy use and transportation
.
