Based on the successful lesson sharing at the first NCA forum, “Natural Capital Accounting for Better Policy,” organized by the Netherlands Ministry of Foreign Affairs and the WAVES Global Partnership in The Hague on November 22– 23, 2016, this publication presents a rich and diverse set of case studies from 12 countries that take stock of NCA, how it engages decision makers, and how it improves policy. This report offers an initial synthesis of achievements, challenges, lessons, tentative principles, and productive ideas for next steps, drawing on experiences and interactions among a range of countries, from low- to high-income countries and those with long or short experience with NCA. The aim is to help NCA developers and policy makers in all countries learn how to obtain good natural capital information to influence real-life policy decisions.
