Coverage

Brazil

Project time

2007

Objectives/scope

Identify fuelwood deficitary areas i.e. fuelwood hot spots by overlapping fuelwood consumption estimates from the residential, commercial and industrial sector with accessible and available resources for the year 2005.

Institutional settings

UNAM – Universidad de São Paulo (USP) - Centro Nacional de Referência em Biomassa (CENBIO)

Scale/resolution

Minimum Administrative Unit: County (5807 units)

Demand features

A re-assessment of fuelwood consumption census data for year 2005 from the statistics bureau (IBGE). Fuelwood consuming sectors considered were: a) residential (e.g. every day cooking), b) agro-industrial (mostly seed drying activities), c) commercial (hotels & restaurants) and d) industrial (wood for charcoal for the pig iron industry).

Supply features

Re-classified world land cover map (17 classes) from MODIS data, crop and projected over the Brazilian territory and linked to fuelwood productivity estimates from the literature review. MODIS raw data was obtained between 2000 and 2001.

Integration features

Mapping of supply/demand balances at the county level.

Woodshed/bio-shed analysis

Not implemented

Integration with other aspects

Not implemented

Findings/conclusions

The report constitutes the first country-wide supply-demand analysis at the county level. The analysis highlighted between 3 to 10 sub-national fuelwood hot spots depending on varying input assumptions. The most critical situations coincide with fuelwood demand census data for pig iron production. The study didn’t include woody plantations, not detected by the land cover map resolution, and flows between native forest harvesting areas and siderurgic facilities. Almost no critical areas appeared over the Amazon basin.
