π°Mangrove restoration has a financing problem. And it starts with the models we use to consider it.
Most planning frameworks treat restoration as a one-off expense with fixed returns. But this misrepresents how ecosystems work and systematically undervalues their services.
Restored mangroves don't deliver their full value on day one. While seedlings develop, carbon sequestration is modest. But mature trees can store up to three times more carbon than in their early years.
π In other words: the returns compound.
That's unlike built infrastructure (like seawalls), which actually depreciate with time.
π This means that every year a restoration project goes unfunded, it is a year of compounding returns lost.
Decision-makers will keep underinvesting in restoration as long as they see it as a static cost on a balance sheet, instead of an appreciating asset.
