Mangroves are salt-tolerant trees and shrubs that grow in tropical and subtropical coastal intertidal regions where freshwater mixes with seawater. They provide natural capital and ecosystem services such as protecting coastlines from floods and storms. While clearing mangroves for wood or shrimp farming can generate under $10,000 per hectare, retaining mangroves and accounting for their flood protection services can value them at over $16,000 per hectare, demonstrating the economic importance of valuing natural capital. Mangroves play a key role in coastal ecosystems and economies.

renewable and non-renewable resources (e.g.
plants, animals, air, water, soils, minerals) that
combine to yield a flow of benefits to people.

11. Natural capital- What is the true value
of Mangroves?
.Natural capital is a stock, and from it flows ecosystem
services or benefits. These services can provide economic,
social, environmental, cultural or spiritual benefits

Thailand, which has moved towards more
environmentally sustainable growth by attempting to
place a value on its mangrove swamps.
Chopping down mangrove for wood gives a return of
less than $1,000 per hectare; removing the
mangroves to make room for a shrimp farm might
generate nearly $10,000 per hectare; but if the
mangrove swamps were retained and their
importance in providing a barrier against floods was
taken into account, they could be valued at more than
$16,000 per hectare.
