The drinking water crisis in India arises due to the overuse, pollution, and unequal distribution of water resources. Rapid urbanization, industrial growth, and population pressure have increased the demand for clean water while reducing its availability.


Step 1: Over-extraction of Groundwater.

Excessive withdrawal of groundwater for agricultural and domestic purposes has lowered water tables in many regions, creating scarcity.


Step 2: Pollution of Water Sources.

Industrial effluents, agricultural chemicals, and sewage discharge into rivers and lakes have contaminated many water sources, making them unsafe for drinking.


Step 3: Unequal Distribution and Poor Management.

Water resources are unevenly distributed across India. Inadequate planning and poor infrastructure contribute to the crisis, particularly in drought-prone and densely populated areas.


Step 4: Climate Change.

Irregular rainfall patterns, prolonged droughts, and depletion of glaciers due to climate change further reduce the availability of clean water.


Step 5: Conclusion.

Therefore, sustainable water management, pollution control, and public awareness are essential to address India’s drinking water crisis.
Quick Tip: Conserve water by reducing wastage, recharging groundwater, and protecting natural water bodies from pollution.

Naturalisation of humans refers to the process by which humans adapt themselves to the natural environment and utilize it according to their needs. It involves the adjustment and harmonious relationship between human beings and nature.


Step 1: Understanding the Concept.

Naturalisation indicates the way humans depend on nature for their survival and development. In earlier stages of human evolution, people were completely dependent on natural forces like climate, vegetation, and landforms.


Step 2: Significance.

It shows the close interdependence between humans and their surroundings. Humans learn to use natural resources wisely while maintaining ecological balance.

The Green Revolution in India refers to a period of agricultural transformation that began in the 1960s, marked by the introduction of high-yielding variety (HYV) seeds, chemical fertilizers, pesticides, and advanced irrigation methods. It aimed to make India self-sufficient in food production.


Step 1: High-Yielding Variety (HYV) Seeds.

The use of HYV seeds for crops like wheat and rice significantly increased agricultural productivity, particularly in states like Punjab, Haryana, and Uttar Pradesh.


Step 2: Use of Chemical Fertilizers and Pesticides.

To enhance soil fertility and protect crops from pests, chemical fertilizers and pesticides were widely adopted during this period.


Step 3: Expansion of Irrigation.

The Green Revolution led to the development of canal systems and tube wells, ensuring the availability of water throughout the year for cultivation.


Step 4: Mechanisation of Agriculture.

The use of modern machinery such as tractors, harvesters, and threshers reduced manual labour and increased efficiency in farming operations.


Step 5: Impact on Economy.

It transformed India from a food-deficient to a food-surplus nation and improved the income of farmers, especially in the northwestern regions. However, it also caused regional imbalances and environmental challenges.
Quick Tip: The Green Revolution made India self-sufficient in food production but also highlighted the need for sustainable agricultural practices.

Water pollution refers to the contamination of water bodies such as rivers, lakes, and oceans due to the discharge of harmful substances like industrial waste, sewage, and chemicals. It affects aquatic life, human health, and the environment.


Step 1: Causes of Water Pollution.

Major causes include industrial effluents, agricultural runoff containing fertilizers and pesticides, domestic sewage, and oil spills. These pollutants degrade the quality of water and disturb the natural ecosystem.


Step 2: Effects of Water Pollution.

Contaminated water leads to the spread of diseases, death of aquatic organisms, and loss of biodiversity. It also disrupts the food chain and reduces the availability of safe drinking water.


Step 3: Control Measures.

Water pollution can be controlled through proper waste treatment, reducing the use of chemical fertilizers, promoting afforestation, and enforcing strict pollution control laws.
Quick Tip: Clean water is essential for all forms of life; preventing water pollution ensures health, sustainability, and ecological balance.

Intensive subsistence agriculture is a type of farming practiced mainly in densely populated regions where farmers cultivate small plots of land with maximum effort to obtain high yields. This type of agriculture is commonly found in South, Southeast, and East Asia.


Step 1: Meaning.

Intensive subsistence farming involves the use of small landholdings with intensive labor to produce food mainly for the farmer’s family consumption, with little surplus for sale.


Step 2: Characteristics.

The main characteristics of intensive subsistence agriculture are:

1. Small landholdings and high population pressure.

2. High use of manual labor and traditional tools.

3. Multiple cropping and use of fertilizers to increase productivity.

4. Irrigation facilities to support cultivation throughout the year.

5. Production mainly for subsistence, though some surplus may be sold.


Step 3: Example.

This type of agriculture is common in countries like India, China, and Indonesia where rice and wheat are the dominant crops.


Step 4: Conclusion.

Hence, intensive subsistence agriculture is labor-intensive, highly productive per unit area, and supports large populations in developing countries.
Quick Tip: Intensive subsistence farming uses limited land efficiently through labor and irrigation to meet food needs of large populations.
