This volume contains presented papers from a workshop on sustainability in the context of nature conservation economics organized at the International Academy for Nature Conservation on the Island of Vilm in October 2007. The papers are divided into four parts: weak vs. strong sustainability and risk assessment, natural capital, scope and boundaries of economic valuation of nature’s goods and services, and practical examples of nature conservation economics. The book gives an overview on the current debate in the sphere of nature conservation economics and sustainability.
