What is Land Equivalent Ratio [LER] ? 20 words
The ratio of land area, which is to be allotted for sole cropping, so as to produce an equivalent yield, is termed Land Equivalent Ratio. The efficacy of land use concerning intercropping systems is, in fact, measured by this ratio.

The Himalayas play a crucial role in shaping the climate of India. This vast mountain range, stretching across five countries (India, Nepal, Bhutan, China, and Pakistan), significantly influences weather patterns, precipitation, and overall climate conditions in the Indian subcontinent. Here’s an in-depth look at how the Himalayas impact India’s climate:
1. Barrier to Cold Winds
Blocking Cold Winds: The Himalayas act as a formidable barrier that prevents the cold Arctic winds from Central Asia from entering India. This helps keep the northern plains of India warmer during the winter months.
Temperature Regulation: By blocking these cold winds, the Himalayas contribute to maintaining relatively moderate winter temperatures in the northern parts of India compared to the extreme cold experienced in Central Asia.
2. Monsoon System
Monsoon Winds: The Himalayas play a vital role in the onset and progression of the Indian monsoon. During the summer, the high temperatures in the Indian subcontinent create a low-pressure area, drawing moisture-laden winds from the Indian Ocean.
Orographic Rainfall: When these moist monsoon winds hit the Himalayan range, they are forced to ascend. As they rise, they cool down and release their moisture in the form of heavy rainfall, particularly on the southern slopes of the Himalayas and in the foothill regions.
Distribution of Rainfall: This process leads to substantial rainfall in regions like the northeastern states and the Indo-Gangetic plains, significantly influencing the agricultural patterns and water availability in these areas.
3. Source of Major Rivers
River Systems: The Himalayas are the source of many of India’s major rivers, including the Ganges, Brahmaputra, and Indus. These rivers are fed by the glaciers and snowmelt from the Himalayas.
Water Supply: The perennial nature of these rivers ensures a continuous supply of water for irrigation, drinking, and industrial purposes, which is essential for the sustenance of millions of people in the northern and eastern parts of India.
4. Microclimates
Local Climate Variations: The diverse topography of the Himalayas creates various microclimates in the region. For example, the southern slopes experience heavy rainfall, while the northern side, in the rain shadow area, receives much less precipitation.
Biodiversity: These microclimates support a wide range of flora and fauna, contributing to the rich biodiversity found in the Himalayan region.
5. Glacial Influence
Temperature Regulation: The glaciers and snowfields of the Himalayas play a crucial role in regulating temperatures by reflecting sunlight and keeping the region cooler.
Climate Change Indicator: The health of Himalayan glaciers is also a key indicator of climate change. Rapid melting of these glaciers due to global warming can have significant impacts on water availability and river flow patterns in the long term.
6. Impact on Weather Extremes
Cyclones and Storms: The presence of the Himalayas affects the intensity and path of cyclones and storms. The mountains can deflect and weaken storms moving from the Bay of Bengal and the Arabian Sea, thereby influencing weather extremes in the region.
In summary, the Himalayas are not just a majestic mountain range but a critical climatic regulator for India. They influence the monsoon patterns, provide water resources, create diverse habitats, and act as a shield against harsh weather conditions, making them indispensable to the region’s climate and ecological balance.

India has always been in touch with nature right from its Agricultural areas self and also reflected in its culture. The most popular Hindu beliefs and everything rooted in mythology consider nature as divine, deifying animals, rivers, forests. A belief in the sacredness of nature is inherent in the Indian Way of Life. This has made it easier for India to balance it’s cultures and the geography with the surrounding natural environment.
The ancient text like Vrikshayurveda lays emphasis on identification of the nature and requirement of the soils and plants in order to cultivate crops in an effective manner. Indian farming has adherence to monsoon and is also safe for diversification of species. Throughout centuries and millennia, small families’ farms have been using seasons and climates, being built to conserve water and soil for growing local food. Crop-growing people hold a god called rain in high esteem and refer to the ground as being a mother figure. There is a great and nurturing attitude to nature prevalent throughout Indian agriculture.
Indian culture has been traditionally associated with the land due to the celebrations of traditional festivity based on the agricultural calendar and phenomena of nature. There are songs and dances to welcome the rains and also for the harvest. Favours of nature are appreciated through NATURE POETRY and geometrical designs of MUGHAL GARDENS and RAJASTHAN FORTS. In Indian arts and crafts, flowers and leaves as well as natural dyes serve as the way to pay homage to the divinity of beauty of growth and the food it offers.
Thus it is seen that Indian culture respects the relationship between humanity and nature where nature is considered as divine, alive and necessary for life’s sustenance and to achieve individual fulfilment. It is this cultural attitude that has been adopted in the conduct of farming in such a way as to sustain both the farmers and the soil.

India’s diverse landscape is a testament to its rich geological history, presenting a fascinating array of physiographic divisions. At the northern border, the Himalayan Mountain Range rises majestically, with its snow-capped peaks and towering summits. This range, stretching from Jammu and Kashmir to Arunachal Pradesh, forms a natural barrier and influences the climate across the subcontinent.
Descending from these lofty heights, the Northern Plains spread out in a broad expanse. Fertile and alluvial, this region is nourished by the Ganges, Yamuna, and other rivers, making it the country’s agricultural heartland.
To the south, the Peninsular Plateau dominates with its rugged terrain, ancient rocks, and rich mineral resources. It is flanked by the Coastal Plains, which stretch along the western and eastern shores, offering stunning landscapes and thriving ecosystems. The Desert Region of the west, particularly the Thar Desert, adds a contrasting element with its arid conditions and unique beauty. Finally, India’s Islands—including the Andaman and Nicobar Islands in the Bay of Bengal and the Lakshadweep Islands in the Arabian Sea—complete the country’s physiographic mosaic, each adding their own charm to India’s geographical diversity.
