“…Biofuels are also major energy sources in the urban areas of the developing countries [Barnes et al, 2001]. In the developed world biofuels are important [Hall, 1991], but provide a smaller fraction of total energy consumed Blandon, 1983].…”

[1] We present an assessment of biofuel use and agricultural field burning in the developing world. We used information from government statistics, energy assessments from the World Bank, and many technical reports, as well as from discussions with experts in agronomy, forestry, and agro-industries. We estimate that 2060 Tg biomass fuel was used in the developing world in 1985; of this, 66% was burned in Asia, and 21% and 13% in Africa and Latin America, respectively. Agricultural waste supplies about 33% of total biofuel use, providing 39%, 29%, and 13% of biofuel use in Asia, Latin America, and Africa, and 41% and 51% of the biofuel use in India and China. We find that 400 Tg of crop residues are burned in the fields, with the fraction of available residue burned in 1985 ranging from 1% in China, 16-30% in the Middle East and India, to about 70% in Indonesia; in Africa about 1% residue is burned in the fields of the northern drylands, but up to 50% in the humid tropics. We distributed this biomass burning on a spatial grid with resolution of 1°Â 1°, and applied emission factors to the amount of dry matter burned to give maps of trace gas emissions in the developing world. The emissions of CO from biofuel use in the developing world, 156 Tg, are about 50% of the estimated global CO emissions from fossil fuel use and industry. The emission of 0.9 Pg C (as CO 2 ) from burning of biofuels and field residues together is small, but nonnegligible when compared with the emissions of CO 2 from fossil fuel use and industry, 5.3 Pg C. The biomass burning source of 10 Tg/yr for CH 4 and 2.2 Tg N/yr of NO x are relatively small when compared with total CH 4 and NO x sources; this source of NO x may be important on a regional basis.

“…The authors have made some modifications based on Reference 5 which result in much higher use than the lEA indicates. Hall (6) estimates that total use is some 50% greater than these revised values.…”

“…Carbon storage can best be 'maximized' when ecosystems are allowed to remain undisturbed or (re)grow to maturity (e.g., climax vegetation), whereas harvest of biomass will result in a reduction of on-site carbon storage. Trade-offs between these two options have been discussed widely (Hall, 1991;Kirschbaum, 2003;Marland and Schlamadinger, 2002;Rosillo-Calle and Hall, 1992;Winjum et al, 1998). One major argument in favour of bioenergy use is the time frame: fossil fuel substitution has the potential to be carried out indefinitely, thus replacing -at least in the calculation -fossil-fuel borne carbon emissions over long periods of time, while carbon sequestration strategies are time-limited and effective only until the ecosystems reach maturity.…”
