Agriculture has been the backbone of India’s economy for centuries, and it continues to play a vital role in the country’s economic development. The sector’s significance and contribution to the GDP have evolved over the decades, influenced by various factors such as technological advancements, government policies, and changing consumer preferences.
Significance of Agriculture in India’s Economy:
- Employment: Agriculture is the largest employer in India, providing employment to around 54% of the workforce (approximately 263 million people).
- Food Security: India is self-sufficient in food production, producing a significant portion of the food consumed domestically.
- Economic Growth: Agriculture contributes around 18% to India’s GDP, making it a crucial sector for economic growth.
- Rural Development: Agriculture is critical for rural development, as it provides income opportunities and social services to rural communities.
Contribution to GDP:
- Historical Context: In the 1950s and 1960s, agriculture contributed around 50% to India’s GDP.
- Post-Green Revolution (1970s-1980s): With the introduction of high-yielding varieties of crops and irrigation facilities, agricultural productivity increased, and its contribution to GDP rose to around 35%.
- 1990s-2000s: The liberalization of the economy led to increased competition and specialization, causing agricultural growth rates to slow down. Its contribution to GDP dropped to around 20%.
- 2010s-present: The agricultural sector has experienced a moderate growth rate, with its contribution to GDP stabilizing around 18%.

Model Answer
Deserts, which cover about one-fifth of Earth’s land area, possess significant resource potential despite their harsh environments. These resources can be harnessed through appropriate technology and sustainable practices.
1. Mineral Resources
For example, the Salar de Atacama in Chile is known for its vast lithium reserves, which are crucial for battery production.
2. Energy Resources
Many desert regions, including the Middle East and Africa, hold substantial petroleum deposits. The Sahara has significant oil shale reserves, while regions like the Arabian Peninsula have mega aquifer systems that provide water for agriculture and human consumption.
Deserts also possess strong potential for renewable energy, particularly solar and wind power, due to their abundant sunlight and consistent winds. Large-scale solar farms are operational in deserts like the Mojave Desert (USA) and Atacama Desert (Chile).
3. Agriculture and Tourism
Despite the arid conditions, xerophytic vegetation and certain crops like date palms, figs, and almonds thrive in desert environments. For example, Israel has successfully transformed the Negev Desert into arable land.
Deserts also attract tourists due to their unique landscapes and cultural heritage, with destinations like the Pyramids of Giza (Egypt) and Jaisalmer’s Desert Safari (India).
