Coverage

Mozambique

Project time

November 2007 – April 2008

Objectives/scope

To enhance the capacity of the country in the formulation of sound wood energy policies and the sustainable management of biomass resources.

Institutional settings

Agriconsulting SpA. Wood Energy Component of the Consolidation Phase of the Integrated Assessment Of Mozambican Forests (AIFM) - Direcção Nacional de Terras e Florestas (DNTF), Ministry of Agriculture. Activity funded by Italian Cooperation.

Scale/resolution

Raster cell resolution = 250 m. Administrative = Posto Administrativo (PA; 427units)

Demand features

Residential consumption in rural areas, small cities (vilas) and larger urban areas (cidades). In order to map the consumption, a population distribution model was created (see Figure 4 in Section 2 “Demand Module”.;
The commercial consumption, (some 10% of urban residential consumption) was based on some data on Maputo covering bakeries, food stalls, restaurants and hotels.
Tobacco drying was the most important industrial consumption that could be estimated and mapped

Supply features

New forest inventory data allowed a detailed definition of non-industrial assortments and thus the estimation and mapping of the productivity accessible and potentially available for energy uses (see Fig. 7 and 8 and Annex 4 for accessibility analysis). Construction material was estimated with reference to an earlier study on hpuse-building requirements and mapped in relation to rural population.The spatial distribution of woody biomass stock and sustainable biomass productivity was done using the MODIS Tree Cover Percent values as proxy of spatialization (see Fig. 10).
Indirect supply sources included mainly the forest industries. By-products potentials were assessed by combining survey data and sector statistics and mapped with reasonable approximation.

Integration features

Local balance: Pixel-level balance and “local neighborhood balance were produced (see examples in Fig 12) with main reference to the energy-subsistence residential consumption.
The “Commercial” balance was produced including several legal and management constraints in order to asses and map the resources effectively available for commercial charcoal production and other bioenergy initiatives (see Fig 13).

Woodshed/bio-shed analysis

Woodshed analysis for Maputo and for Beira-Chimoio was carried out considering “conservative” and “liberal” commercial balances. In addition, two different management regimes were assumed: a 100% regime, and a 50% (see Fig 16 for Maputo woodsheds) . An analysis of deforestation/degradation risk zoning was done within the Maputo woodshed in which, within the estimated sustainable supply zone, the risk level was set to be inversely proportional to the distance from the city.

Integration with other aspects

Not applied but highly recommended.

Findings/conclusions

WISDOM gained a central role in the inter-institutional Advisory Group that supports the formulation of the National Biomass Plan. The process used and promoted important synergies among the DNTF, the University, energy agencies and other parties of the advisory group.
Definition of critical data gaps and weaknesses for further investigations.
