Step 1: Understanding the Question:
The question asks for the proportion of India's total geographical area (328.7 million hectares) that is used for agricultural activities.
Step 2: Detailed Explanation:
• Land Use Pattern: India has one of the highest percentages of arable land in the world. The major land-use categories include forests, non-agricultural land, barren land, and agricultural land (Net Sown Area).
• Statistical Breakdown: According to the latest land-use statistics provided by the Ministry of Agriculture, the "Net Sown Area" in India is approximately 141 million hectares.
• Calculation: When including current fallow and other fallow lands, the total agricultural land area accounts for approximately 51% to 54% of the total reporting area.
• Global Comparison: This 51% is significantly higher than the global average of roughly 11%, making India an agrarian-intensive nation.
• Management Implications: With such a high percentage under agriculture, there is significant pressure on land resources, highlighting the need for agroforestry to integrate trees into these farming systems for ecological stability.
Step 3: Final Answer:
The total area under agricultural production is around 51 per cent of the total land area in India.
