Sustainable and Thriving Environments for West African Regional Development

The Sustainable and Thriving Environments for West African Regional Development (STEWARD) project is a join investment of Economic Growth, Agriculture and Trade Bureau (EGAT), USAID/West Africa and the US Forest Service. It is implemented by Bioclimate Research & Development (BR&D).

LTS provide technical support to the STEWARD Project. The objective of this is to provide an assessment of biomass stocks and biomass stock change between 2007 and 2010 in a specified area of Sierra Leone/Guinea border region.

The assessment is undertaken using multi-regression analysis of RADAR data and generation of biomass maps using a range of biomass-backscatter equations.

Based on best output validation, LTS will then calculate statistics on forest area and biomass stock loss within the time frame investigated.

The project also aims to achieve:

  • Agreement of change classification criteria and project-specific deforestation threshold
  • Advice on RADAR data purchasing from RESTEC
  • Multi-regression analysis of RADAR data and generation of biomass maps using different biomass-backscatter equations
  • Multi-validation of outputs against field data provided by BR&D
  • Generation of biomass stock change statistics and maps

West Africa Forest Strategy

The Upper Guinea High Forest in the West African countries of Guinea, Sierra Leone, Liberia, Ivory Coast and Ghana represents a diversity of ecosystems made up of savannas, semi-deciduous tropical forests and tropical rain forests. Loss of forest cover and degradation of forested land continues at a rapid pace. The West African Forest Strategy (WAFS) formulation process required an assessment of the sector to provide the World Bank with strategic direction aimed at creating a sustainable and productive forestry sector that fuels growth. The WAFS contributed to the fine tuning of a wider African Forestry Strategy and assisted the World Bank in consolidating its support to forestry in the region and aimed to provide a more systematic engagement on forestry issues at a regional level. LTS undertook a forest sector analysis using a gap model framework, a policy options analysis and developed the strategy and financing instruments. Please click here to read the report.

Environmental Impact Assessment of the Bumbuna Hydro Electric Dam

The Bumbuna Hydroelectric Project (BHP) was located on the Seli River, about 250 km northeast of Freetown, Sierra Leone. It consists of an asphalt-faced rock-filled dam (88 meters high), two multipurpose tunnels and a powerhouse at the base of the dam with a design capacity of 50 MW. The BHP is the first stage of a five-stage program for 275 MW ultimate capacity. A single-circuit 161 kV transmission line transfers Bumbuna’s power to Freetown and intermediate towns. An Environmental Impact Assessment (EIA) for the Bumbuna Hydroelectric Project was prepared in 1995. However, the original EIA was prepared under the constraints of an emerging civil war and was out of date and non-compliant with current World Bank operational guidelines. In 2004, LTS participated in a consortium responsible for updating the EIA. Our specialist team conducted a rapid biodiversity and land management assessment of the reservoir and immediate catchment areas in order to determine whether endemic or rare species and land-based livelihoods will be adversely affected by the project.
