Human well-being is entirely dependent on ecosystem and biodiversity, yet these resources and their own values are being degraded dramatically as the human society is developed. Ecosystem service could be a criterion for valuing natural resources, regarding the preservation of natural resources and their uses. Nevertheless, the Millennium Ecosystem Assessment identified the systematic under-valuation on ecosystem service and the failure to capture its value. The partial solution to internalize ecosystem service lies in policy making that takes into account the full value to this- the benefits gained from ecosystems to individuals, communities, economy, and the costs of those benefit.
Considerable progress in the measurements and valuation of ecosystem service has been made, and a large number of case studies and demonstration projects have been undertaken. The valuation of ecosystem service has been widely accepted in the environment community, but the challenge remains as ‘How to engage the development-oriented perspective (the view that prioritizes development over ecosystem service) and national policy.’
To meet this challenge, ecosystem valuation should focus on integrating values of ecosystem service into environmental assessment. In order to integrate ecosystem service assessment into environmental assessment, it is necessary to predict the changes that are expected to occur and prepare the measures for such changes. Since ecosystem service contains ecological, social and economic values, it is urgently needed how to measure these values into an integrated framework.
In this workshop, we will discuss the methodologies and the case studies of ecosystem service that have been developed domestically and internationally, including the evaluation on how to integrate ecosystem service assessment into environmental assessment and why such integration is important.
