(i) Explain land use pattern in India and why has the land under forest not increased much since 1960-61?
(ii) How have technical and economic development led to more consumption of resources?
Answer: (I) The land use pattern in India involves diverse uses, including agriculture, forestry, mining, construction, and other activities. Since 1960-61, the land under forest in India has not increased significantly due to several factors:
- The growing population has led to increased demand for food, resulting in the conversion of forest land to agricultural land.
- Rapid urbanization and industrialization have required more land, often at the expense of forest areas.
- Over the years, forests have been overexploited for timber, fuelwood, and other resources, leading to deforestation.
- While there have been policies aimed at increasing forest cover, their implementation has often been ineffective or insufficient.
(ii) Technical and economic development has led to more consumption of resources on account of various factors such as:
- Technological advancements have enabled mass production in industries, increasing the consumption of natural resources like minerals, fossil fuels, and water.
- Economic development has fueled urbanization, leading to the construction of more buildings, roads, and infrastructure, thereby consuming large amounts of materials like cement, steel, and energy.
- Technological advancements in transportation have resulted in more vehicles and travel, increasing the consumption of fossil fuels.
