Understanding Ecosystem Engineering in Coastal Environments

Coastal ecosystems - mangroves, salt marshes, seagrades beds, and coral reefs - are among te most productiva and biodiverse habitats on Earth. They also serve as natural barriors against te intensifying effects of climate change.

Thee Role of Ecosystem Engineering in Climate Adaptation

Climate adaptation refers to actions taken to adjuss te actual or expected effects of climate change. For coasure area, this means reducting to hazards like sea- level rise, expected storm intensity, looding, and shoreline erosion.
