Biomass Crises in India: The Case of Fuelwood

Even though many continue to hold on to the notion of a fuelwood crisis in India (try a search on it) it is quite apparent that the crisis hasn’t materialised as feared. For a useful summary see this RFF paper on the subject.

What happened? Briefly, in rural India people responded by substituting fuels and augmenting production. The RFF paper cited above provides one such illuminating case study from Madhya Pradesh.

To know what is happening with bio-fuels on all-India basis is extremely hard as data is not available but we do know a few things. Biomass increases have come from agricultural residues (agricultural production has grown 2.5% CAGR for the past 55 years); dung (livestock population up 1% CAGR along with increased fodder availability); and woody biomass from trees grown on private, community and government lands. Of course all incremental production is not available as fuel and woody biomass has reduced in many areas.

I wish to focus, however, on a potentially far-reaching development that may be underway - increasing use of LPG in rural areas. According to the NSSO “The proportion of households using LPG increased six-fold in rural India from about 2% in 1993-94 to 11.7% in 2004-05. See also this note by the NSSO for primary energy use. Since kerosene is not used in rural areas for cooking it may be safely inferred that such use is replacing bio-fuels.

In urban areas too LPG use has grown rapidly. The proportion of households using LPG doubled in urban India from 29.5% in 1993-94 to 59% in 2004-05. See the two sources cited above. But LPG in urban India may be replacing SKO (Superior Kerosene Oil) rather than bio-fuels, the latter still continue to the primary cooking fuel for about 20% of the households.

It is instructive to see what is happening with LPG. The tables below give some data:

Both tables reflect the stupendous rates of the growth in number of LPG customers and use. SKO has stagnated as it gets phased out as cooking fuel and also but less so for lighting. The high rates of LPG use, far in excess of per capita income growth, in certain periods, suggest latent demand not met due to supply constraints.

These constraints have now largely disappeared due to increases in domestic refining capacities and import facilities at ports in the past 10-20 years. In addition, huge gas discoveries in KG basin and ample foreign exchange reserves will make supplies a non-issue within a couple of years. Supplies have not yet been fully eased in rural areas as affordability is much more than indicated by the 11% households presently using LPG.

The constraint of the initial high capital cost has been eased in several states by providing subsidies on the purchase of stoves, smaller cylinders are provided in hilly areas but perhaps the largest factor may be growing incomes of households and a desire for clean and convenient fuel.

Use of LPG is still quite low, especially in rural India but is growing rapidly. It seems such rates may be sustained. If so, for the vast numbers of women living in abysmal conditions in the country, this development may turn out to be more meaningful and have a more durable positive impact than having a woman president.
