Rwanda |
Project time |
February – December 2009 |
Objectives/scope |
Improvement of the knowledge on wood energy supply and demand in the Country, in order to support sound policy formulation and planning, and the strengthening of national capacities. |
Institutional settings |
Project TCP/RWA/3103 - Rationalisation de la filière bois-énergie. Project executed with FAO financial and technical support by the National Forest Authority, Ministry of Natural Resources (MINIRENA), with participation of other national institutions and ministries. |
Scale/resolution |
Raster cell resolution = 50 m |
Demand features |
Residential consumption in rural and urban areas). In order to map the consumption, a population distribution model was created using 2002 census data, “10 households” map points and updated urban areas (Google Earth). |
Supply features |
The land cover base map was produced merging recent map of plantations and natural forests with LCCS-based Africover Map of Rwanda. The available woody biomass resources were estimated and mapped based on plantations inventory data, productivity by LCCS classes derived from WISDOM East-Central Africa and one ad-hoc survey of trees and shrubs in rural areas (interpretation of high-resolution orthophoto over a systematic sample of non-forest areas). Two variants were considered: one “business as usual” (BAU) and one “managed” (MAN) with higher productivity based on the observation of basic management prescriptions. |
Integration features |
The supply/demand balance was estimated and mapped at pixel level in a local context of 1.5 km and by administrative unit (Sector, District). Several balances were produced, depending on the supply and demand variants considered (BAU-BAU; BAU-AME; MAN-BAU; MAN-AME) (see Figure A3.28). In addition, balance mapping was done considering that a fraction of the woody biomass be replaced by farm residues. |
Woodshed/bio-shed analysis |
The overall negative balance prevent the delineation of sustainable supply zones. At current conditions none of the major cities can have sustainable woodsheds. |
Integration with other aspects |
Balance conditions and poverty parameters were combined to quantify and identify the populations living concomitant conditions of woodfuel deficit and extreme poverty, which represent a condition of severe vulnerability (see figure_in “Thematic coverage” Section). |
Findings/conclusions |
The national supply/demand balance, according to current situation shows an annual deficit of 1.8 Mt.(oven-dry). With improved management and conversion efficiencies (but the same plantation area) the balance could raise to a deficit of “only” 0.75 Mt. |
