The socio-economic development plan for Sekong mentions increasing forest cover as one of its major objectives. This study focuses on natural regeneration (NFR) forests and what it would cost the country if NFR schemes were not undertaken. In a country where poverty alleviation is of prime importance, estimating the contribution of NTFP harvesting for sustaining livelihoods would demonstrate the importance of NFR schemes in achieving its poverty alleviation goals.

This publication attempts to address the challenge of using water ecosystem valuation to strengthen river basin management, and to demonstrate its practical utility for decision making.
