What does farmer’s despair over crop failure have in common with dengue fever, which is ravaging Delhi and other cities of India? Seemingly nothing. But dig a little deeper and you will find that in both cases variable and erratic weather is at the root of these tragic events. There is another connection: lack of governmental policy, action and, quite frankly, callous neglect that has made both events even more horrific and painful. Last fortnight, I wrote about the killing fields of India, where unseasonal, extreme and deficient rainfall had driven farmers to despair.
