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 is it important to protect land from degradation?
However, soils play an important role in land degradation and conservation as they directly influence other “land” elements such as vegetation (through supplying nutrients and plant available moisture) and water (buffering and filtering function), and through these men and animals.
How do humans affect land degradation?
Human interventions which are causing land degradation are (1) deforestation , (2) overgrazing by livestock, (3) mismanagement of agricultural land, (4) overexploitation of the vegetative cover for domestic use, and (5) (bio)industrial activities.
What is land degradation How can we solve the problem of land degradation?
(i) Afforestation over deforested areas . (ii) Proper management of grazing on permanent pastures. (iii) In areas where, desertification has taken place, growing thorny bushes. (iv) Proper discharge and disposal of industrial effluents after treatment.
