Mangrove ecosystems

Mangroves are among the most valuable ecosystems providing food and protection for a large number of marine and land-based organisms, livelihoods for coastal populations, and protection from ocean swell and other extreme weather events for low-lying coastal areas. In the wake of the 2004 Indian ocean tsunami there was a strong realization that much of the future devastation to human life and property could be avoided through the existence of healthy, properly-managed and conserved mangroves.

Mangroves are among the most important ecosystems on the planet. They provide food and protection for a huge variety of marine and land-based species, sustain livelihoods of coastal populations, and provide protection from ocean swell and extreme weather events. Today, however, the world’s mangroves are under threat from several sources including coastal development and the impacts of climate change.

This book presents the economic justification for including mangrove rehabilitation and restoration efforts in current tsunami reconstruction projects in Sri Lanka. The results provide a solid platform for the decision makers to select the best development strategies for the tsunami-affected communities by comparing the results provided by this study with the value of alternative uses of mangroves in these areas.

Building resilience into mangrove conservation plans requires an understanding of how mangroves will respond to climate changes, what factors help them survive these changes, and, consequently, which mangroves are most likely to survive these changes. This publication provides a welcome reference for all stakeholders in mangroves, especially coastal communities, to assist them in encouraging decision makers to apply resilience principles in all development and conservation programmes.

The Indian Ocean tsunami of 2004 and the catastrophic hurricane season in the Gulf of Mexico in 2005 have had tragic and devastating consequences for the global community and have drawn attention to the vulnerability of tropical coastal ecosystems. The lessons learnt from these events are critically relevant to future management of the coast. More than ever it is essential to consider the full value of ‘ecosystem services’ when making decisions about coastal development.
