Policy-makers who factor the planet's multi-trillion dollar ecosystem services into their national and international investment strategies are likely to see far higher rates of return and stronger economic growth in the 21st century. Some countries have already made the link to a limited extent and are glimpsing benefits in terms of jobs, livelihoods and economic returns that outstrip those wedded to older economic models of the previous century. This report calls on policy-makers to accelerate, scale-up and embed investments in the management and restoration of ecosystems. It also calls for more sophisticated cost benefit analysis before policy-decisions are made. The report cites a study on mangroves in south Thailand on the conversion of mangroves into shrimp farms.
