Measuring Prosperity Session 10 – Evaluating and Realizing the Value of Nature: Insights from the Changing Wealth of Nations Database and Examples from Indonesia

Evaluating and Realizing the Value of Nature: Insights from the Changing Wealth of Nations database and examples from Indonesia

The Changing Wealth of Nations (CWON) series of reports provides a database and analysis of the world’s wealth accounts spanning 146 countries, annually from 1995 to 2018. It tracks human capital, a wide range of natural capital (including fisheries, forests, and mangroves), produced capital, financial capital, and more. The next version of the CWON database and report is currently in development. This presentation will look at key findings from CWON 2021 as well as discuss changes in the upcoming report. It then considers two examples of ecosystems valuation, conceptually linking wealth accounting to applied scenario analysis for informing policy. Examples are taken from Indonesia, which has a variety of initiatives underway to improve accounting of natural capital. The country has also embarked on significant investments in natural capital, including mangroves (towards a target of 600,000 ha restored or under improved protection by 2024), and forestry (towards net zero emissions from forest and land sectors by 2030). Ecosystems valuation – which demonstrates the considerable value of mangroves is a useful tool in the design of these investments.
