Dr. Vandana Shiva: climate change, drought, and India's looming food and water crisis

Intensification of drought, floods and cyclones is one of the predictable impacts of climate change and climate instability. The failure of monsoon in India and the consequent drought, has impacted two thirds of India, especially the bread basket of India’s fertile gangetic plains. Bihar has had a 43% rainfall deficit, Jharkhand – 47%, Uttar Pradesh – 64%, Haryana – 61%, Punjab – 26%, Himachal Pradesh – 63%, Uttarakhand – 42%.

In the final analysis, India’s food security rests on the monsoon. Monsoon failure and widespread drought implies a deepening of the already severe food crisis triggered by trade liberalization policies which has made India the capital of hunger. It also implies a deepening of the water crisis which compelled me to write “Water Wars”.

The monsoons recharge the groundwater and surface water systems. This year, because of drought there will be reduced recharge. Since 1966, as a consequence of the introduction of the Green Revolution model of water intensive chemical farming under World Bank and US pressure, India has over exploited her ground water, creating a water famine. I had written about this in 1984 in my book, “The Violence of the Green Revolution”. Chemical monocultures of the Green Revolution use of ten times more water than the biodiverse ecological farming systems.

In the 1970’s the World Bank gave massive loans to India to promote ground water mining. It forced states like Maharashtra to stop growing water prudent millets like jowar which needs 300 mm of water and shift to water guzzling crops like sugarcane which needs 2500 mm of water. In a region with 600mm rainfall and 10% ground water rechange, this is a recipe for water famine (see Navdanya’s “Financing the Water Crisis).

A new study led by Matthew Rodell of Nasa’s Goddard Space Flight Center in Maryland published in “Nature” has shown water levels in North India have fallen by 1.6 inches (4 centimeters per year, between August 2002 and August 2008. More than 26 cubic miles (109 cubic km) of ground water have disappeared from aquifers between 2002 and 2008. Most of this ground water has been extracted for chemical, green revolution style farming.

Not only has water wasteful chemical agriculture mined ground water, it has also mined soil fertility and contributed to climate change. Chemical fertilizers destroy the living processes of the soil and make soils more vulnerable to drought. Chemical fertilizers also produce nitrogen oxygen, a greenhouse gas which is 300 times more potent the carbon dioxide.

The solution for the climate crisis, the food crisis, or the water crisis, under which India is reeling, the same biodiversity based organic farming systems.

Biodiverse ecological farms address the climate crisis by reducing emissions of Green House gases such as nitrogen oxide, and absorbing carbon dioxide in plants and in the soil. Biodiversity and soils are the most effective carbon sinks. They also help adapt to climate change and drought by increasing soil organic matter which increases the moisture holding capacity of soil, and hence provides drought proofing of agriculture.
