The world needs to quadruple its annual investment in nature if the climate, biodiversity and land degradation crises are to be tackled by the middle of the century, according to a new UN report.
Investing just 0.1% of global GDP every year in restorative agriculture, forests, pollution management and protected areas to close a $4.1tn (£2.9tn) financial gap by 2050 could avoid the breakdown of natural ecosystem “services” such as clean water, food and flood protection, the report said.
