Mira Kamdar: The threat of global food shortages

Last month, the wheat fields in Punjab stretched in amber-tinged waves as far as the eye could see, promising bountiful harvests. Nothing hinted at the grave crisis that has gripped the state, driving farmers to suicide and unemployed youth to the comforts of heroin. Dubbed "the breadbasket of India," Punjab is in the throws of a serious crisis, one that bodes ill for the future of agriculture at a time when the world faces an acute food crisis.

Punjab's grand narrative, a success story of bumper harvests, conceals dangerous subplots of pesticide poisoning, water shortages, soil salinity, fertiliser runoff, skyrocketing cancer rates, farmer indebtedness and drug addiction. Viewed in the context of a report released on April 15 by the Assessment of Agricultural Knowledge, Science and Technology for Development (IAAKSTD), an intergovernmental entity initiated by the World Bank and the United Nations Food and Agricultural Organisation (FAO), Punjab's saga is a case study in how industrial agriculture boosts yields in the short term, but leads to the long-term destruction of the land on which agriculture depends and of the social and environmental context with which it's intimately linked.

The result of three years of study undertaken by 400 experts, the IAAKSTD report comes to an urgent conclusion: "Business as usual is not an option." Robert Watson, IAAKSTD director, warns that if radical changes aren't made in how we produce and distribute our food, "the world's people cannot be fed over the next half-century," and we will be left with "a world nobody wants to inhabit."

In the early decades of independence, a fledgling Indian democracy had trouble meeting its basic food needs. By the mid-1960s, facing mass famine, the proud young nation had to go begging for emergency food assistance. The Green Revolution arrived in India shortly thereafter. Yields skyrocketed. Attaining self-sufficiency in food was a proud achievement for a nation weaned on the Gandhian notion of swadeshi, or national self-sufficiency. In 1995, India catapulted into the ranks of the world's food exporters. Even those who lamented a starkly inefficient distribution system that left many hungry admitted that India did produce enough food.

Nowhere in India did the Green Revolution work its magic as it did in Punjab. Punjab became the poster-child for the power of agricultural science to extract from the Earth an unprecedented level of productive capacity. New hybrid seeds, massive irrigation projects and synthetic fertilisers transformed ordinary crops into the equivalent of athletes on steroids. Mechanisation arrived in the form of tractors, reducing man-hours required in the fields. With just 1.5 per cent of the nation's land, Punjab produces 20 per cent of India's wheat and 12 per cent of its rice.

But Punjab's agricultural miracle can no longer keep pace with India's growing need for food. Every year, India adds 18 million people to its population, the equivalent of an Australia. Nor can it compensate for the rest of the country's lower agricultural productivity. India's booming services and industrial sectors together drove overall economic growth last year to a record level of 9.7 per cent. However, agriculture, on which 70 per cent of India's people still depend for survival, actually contracted from a lacklustre 3.8 per cent growth rate to a dismal 2.8 per cent rate.

Meanwhile, India's emerging middle classes demand more food, especially more animal products such as milk, eggs, poultry and meat
