This forest data assessment was conducted as part of the five-year Global Transformation of Forests for People and Climate: a focus on West Africa project, funded by the Swedish International Development Cooperation Agency (Sida). This document aims to provide quality data to support decision-making and sustainable management of forest and land resources at both national and subregional levels. It also seeks to develop processes that could be replicated in other subregions within Africa and outside the region. This document is one of the outputs of the project and provides information on existing forest data in the Economic Community of West African States (ECOWAS) countries, critical information gaps on forest condition and land use and land cover dynamics, and capacity development needs.
