Explain the benefits of the Indira Gandhi Canal in its command area.
Show Hint
Solution and Explanation
Regional planning and sustainable development, specifically the impact of major irrigation projects in arid regions.
Step 2: Meaning
The Indira Gandhi Canal is a massive irrigation project that brought water from the Harike Barrage in Punjab to the dry Thar Desert regions of Rajasthan, transforming the local ecology and economy.
Step 3: Analysis
• Ecological Transformation: The constant availability of irrigation water has increased soil moisture and facilitated widespread afforestation, greening a historically barren desert landscape.
• Agricultural Shift: It has allowed farmers to transition from traditional, low-yield drought-resistant crops (like gram and bajra) to highly profitable commercial crops (such as wheat, cotton, groundnut, and mustard).
• Economic Boost: The massive increase in agricultural production and improved livestock rearing have directly elevated the income levels and food security of the regional population.
• Drinking Water: It has provided a reliable, permanent source of drinking water for both humans and livestock in districts that historically faced severe water scarcity.
Step 4: Conclusion
The Indira Gandhi Canal has acted as a vital lifeline for western Rajasthan, converting a dry desert into a productive agricultural zone and drastically improving the standard of living.

Read the passage carefully and answer the questions that follow:
Hunting and Food Gathering
The earliest human beings depended on their immediate environment for their sustenance. They subsisted on: (a) animals which they hunted; and (b) the edible plants which they gathered from forests in the vicinity. Primitive societies depended on wild animals. People located in very cold and extremely hot climates survived on hunting. The people in the coastal areas still catch fish though fishing has experienced modernisation due to technological development. Many species, now have become extinct or endangered due to illegal hunting (poaching). The early hunters used primitive tools made of stones, twigs or arrows so the number of animals killed was limited. Gathering and hunting are the oldest economic activity known. These are carried out at different levels with different orientations. Gathering is practised in regions with harsh climatic conditions. It often involves primitive societies, who extract both plants and animals to satisfy their needs for food, shelter and clothing. This type of activity requires a small amount of capital investment and operates at very low levels of technology. The yield per person is very low and little or no surplus is produced.- Examine the role of climate, water availability, and soil fertility on the distribution of world population.
