Social Science — CBSE Class 10 board question

Two ways to solve the problem of land degradation:

1. Afforestation – Planting trees and proper management of grazing helps restore degraded land and prevents further soil erosion.
2. Control of mining activities – Proper discharge and disposal of industrial effluents and wastes after treatment reduces land and water degradation.

The textbook lists several methods — afforestation, shelter belts, controlled overgrazing, stabilisation of sand dunes, and proper industrial waste disposal. For a 2-mark question, name two distinct methods with a brief reason each. Avoid listing only headings without explanation — examiners expect one supporting line per point.
