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.

The four main Rabi crops of India are:
(1) Wheat
(2) Barley
(3) Gram (Chickpea)
(4) Mustard
Step 1: Understanding Rabi Crops.
Rabi crops are those crops that are sown in the winter season (October–December) and harvested in the summer season (April–June). They require cool weather for growth and warm conditions for harvesting.
Step 2: Regions of Cultivation.
Rabi crops are mainly grown in northern and northwestern states of India such as Punjab, Haryana, Uttar Pradesh, and Madhya Pradesh.
Step 3: Importance.

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.

Step 1: Define land degradation. Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. It means a decline in the quality and productivity of the land.

Step 2: Analyze the options as causes of degradation.

Soil alkalinity: High levels of alkaline salts in the soil make it infertile and unsuitable for agriculture.
Soil erosion: The removal of the top, fertile layer of soil by wind or water reduces land productivity.
Waterlogging: Excessive accumulation of water in the soil's root zone suffocates plants and leads to salinization, degrading the land.

Step 3: Conclude based on the analysis. All three are major causes of land degradation.
