3. Answer the following questions in about 120 words.
(i) Explain land use pattern in India and why has the land under forest not increased much since 1960-61?
Ans: Land Use Pattern in India and Forest Land Increase Since 1960-61
India’s land use pattern is diverse, influenced by physical factors like topography, climate, and soil types, as well as human factors such as population density and technological advancements. The major categories of land use include agricultural land, forest land, pasture, and wasteland. Currently, approximately 54% of the land is under net sown area, while forest cover is around 22%, which is significantly lower than the desired 33% as per the National Forest Policy of 1952.
The limited increase in forest land since 1960-61 can be attributed to several factors. Deforestation for agricultural expansion, urbanization, and industrial development has led to the degradation of forest areas. Additionally, improper land management practices and overgrazing have further hindered forest regeneration. Conservation efforts have not been sufficient to counteract these pressures, resulting in minimal growth in forest cover over the decades.
In conclusion, while India has a rich variety of land uses, the challenges of deforestation and land degradation have significantly impacted the growth of forest areas, necessitating more effective conservation strategies.
Recommendations:
Encourage sustainable agricultural practices to reduce pressure on forest land.
- Implement stricter regulations on land use to protect forest areas.
