Will Jatropha Impact Food Prices?

It wasn’t long ago that corn ethanol seemed like a win-win idea from all angles. In the US, farmers, environmentalists and politicians of all stripes piled on. A few did acknowledge that Brazilian sugarcane was a better idea, and even fewer did point out the risk to food prices, but overall their voices and better sense were drowned by a wave of euphoria around corn ethanol.

Energy prices, of course, are the main cause behind increase in food prices, but not many dispute the fact that corn ethanol had a role too. In hindsight, that relationship is not hard to grasp: when demand for corn surged, the price did too without a similar spike in supply. It’s economics 101 – basic supply and demand.

Now, consider another plant that’s being widely touted as the ideal source of biofuels – jatropha. Jatropha is not a food crop,and it can be grown in barren and waste land with relatively little water. What’s not to like, huh?

Well, let’s apply some basic economics principles to this situation. Whenever the market price for a certain product increases, there will be more willing suppliers of that product. And that will be true for jatropha seeds too.

Large areas of the country have increasingly experienced drought conditions. Maharashtra, Andhra Pradesh, Madhya Pradesh and Karnataka have seen thousands of farmer suicides in recent years because of crop failures due to drought. It is not far fetched to think some of these farmers might find it easier to grow jatropha than, say, rice.

Leveling rice and wheat yields per hectare is a worrying sign in itself. If fuel crops like jatropha intrude into this traditional crop land, the price pressures on food grain will be compounded.

As the euphoria around jatropha grows, it will pay to remember the harsh lessons learnt from the corn ethanol experience. India has more than enough waste and barren land suitable for jatropha – 63.85 million hectares – to make a significant dent in the nation’s energy needs even with low biodiesel yields (say 650 litres/hectare as opposed to published highs of 1800 or 2200 litres/hectare).

If jatropha is allowed to take over too much food grain land, however, the only way to compensate for that with very little fertile land left to cultivate, will be with efficiency increases in food crops. And that’s something the country has failed to achieve in the last few years.
