The Green Revolution was primarily aimed at increasing agricultural productivity in India to meet the growing demand for food due to a rapidly increasing population.

Organic farming practices were not a key technology introduced during the Green Revolution in India. The focus was on increasing productivity through the use of high-yielding varieties of seeds, chemical fertilizers, and pesticides.

M.S. Swaminathan is widely regarded as the father of the Green Revolution in India for his pioneering work in developing high-yielding varieties of wheat and rice.

Punjab was the first state in India to adopt the Green Revolution technologies, particularly the high-yielding varieties of wheat, and became known as the 'breadbasket of India'.

The Green Revolution had a profound impact on food production in India, leading to a significant increase in food production, reducing the country's dependence on food imports, and improving the nutritional status of the population.

Cotton was not a major beneficiary of the Green Revolution in India. The focus was primarily on increasing the production of food grains such as wheat and rice.

The Green Revolution in India had some negative consequences, including increased use of chemical fertilizers and pesticides leading to environmental degradation, displacement of small and marginal farmers, and exacerbation of regional disparities in agricultural development.

Declining water resources is not a key challenge faced by Indian agriculture today. The other options are all major challenges that need to be addressed to ensure sustainable agricultural development.

The current focus of agricultural research and development in India encompasses developing drought-resistant and climate-resilient crop varieties, promoting sustainable and organic farming practices, and improving irrigation and water management systems.

Farmers in India can adapt to the challenges of climate change and ensure sustainable agricultural practices by adopting crop diversification and intercropping techniques, using water-efficient irrigation methods, implementing soil conservation measures, and promoting agroforestry.
