write down the factor which can lead to degradation
Answers
Explanation:
Some of the factors responsible for land degradation are (i) loss of vegetation occuring due to deforestation (ii) unsustainable fuel wood and fodder extraction (iii) shifting cultivation (iv) encroachment into forest lands (v) forest fires and over grazing (vi) non-adoption of adequate soil conservation measures (vii) improper crop rotation (viii) indiscriminate use of agro-chemicals such as fertilisers and pesticides (ix) improper planning and management of irrigation systems (x) extraction of ground water in the competing uses of land for forestry, agriculture, pastures, human settlements and industries
Answer:
Land degradation is a global problem largely related to agricultural use, deforestation and climate change. Causes include:
Land clearance, such as clearcutting and deforestation
Agricultural depletion of soil nutrients through poor farming practices
Livestock including overgrazing and overdrafting
Inappropriate irrigation[9] and overdrafting
Urban sprawl and commercial development
Vehicle off-roading
Quarrying of stone, sand, ore and minerals
Increase in field size due to economies of scale, reducing shelter for wildlife, as hedgerows and copses disappear
Exposure of naked soil after harvesting by heavy equipment
Monoculture, destabilizing the local ecosystem
Dumping of non-biodegradable trash, such as plastics
Invasive Species
Climate change
Loss of soil carbon
