Global steel giants ArcelorMittal (MT) and Posco are leading $80 billion in planned spending in India, an investment that would vault the country ahead of Japan as the second-biggest steelmaker. There's one hurdle: India's farmers and their water supply. The farmers refuse to move from irrigated land in three states that hold more than half of India's reserves of iron ore, a key material used in the making of steel....

In our frantic search for solutions to our water crisis, we tend to overlook the self-evident relationship between water, food, and energy. It is still not too late. As my colleague Tony Allan, a Stockholm Water Prize laureate says so pithily, the three are the corners of a triangle with politics and emotion at its center.

With a gas-guzzler of an economy, India had been spending tens of billions of dollars annually to import petroleum. And so its 2009 policy on biofuels mandated that by 2017, India would have enough biofuel production to cover at least 20 percent of the country’s oil consumption. The government has in fact been encouraging the cultivation of jatropha curcas for the past seven years, believing that would be the fastest way...

In 2007-08, food prices soared. Mozambique and 30 poor countries endured food-price riots. Russia led a procession of grain exporters to restrict sales. And the world had to face up to changes in the pattern of food demand, reversing decades of declining...

And it is happening right across our home. From the cold desert of Ladakh to the plains of Bihar and Jharkhand, extreme weather conditions have played havoc. In neighbouring Pakistan, unprecedented floods, and that too in the arid region of Sindh, have hit more than...
