A study looks at how households adapt to slow-moving environmental changes such as groundwater depletion.

Like in many parts of India, Karnataka’s groundwater is a vital source of irrigation water, but has been depleted by a combination of a prolonged, multi-year drought and intensive extraction. Worsening agro-climatic and environmental conditions are threatening the incomes of smallholder farmers and hampering the continued progress in poverty eradication.

Zero budget natural farming can lead to huge savings in fertiliser subsidy, says study

A recent study by the Council on Energy, Environment and Water offers insights into Zero Budget Natural Farming (ZBNF) vis-à-vis its effect on the economics of agriculture in Andhra Pradesh. The study titled ‘Can Zero Budget Natural Farming Save Input Costs and Fertiliser Subsidies? Evidence from Andhra Pradesh’ compares costs of ZBNF inputs and practices with the costs of chemical inputs such as fertilisers and pesticides for the farmer.

A study highlights the need to scale down the export of rice, maize, buffalo meat and other items to conserve groundwater in India.

The recent trade war between the United States and China was, among other things, about virtual water - the hidden water in products. Producing anything, whether it is soyabean or clothes, uses water, and has a water footprint. Even after production, shipping and trading also have a hidden water cost.

A study calls for solutions that can benefit farmers and the environment and positively impact India's nutrition indicators.

A new study finds that introducing coarse cereals such as millet and sorghum could improve India’s national food supply in many ways. The study by the Data Science Institute at Columbia University found that India’s agricultural policies have largely focused on the single objective of maximizing production, and not enough attention has been given to nutrition, climate, and environment.
