NATURE’S SUPERHEROES IN THE FIGHT AGAINST CLIMATE CHANGE

Coastal ecosystems such as mangroves, tidal marshes and seagrasses play a significant role as carbon sinks in the fight against climate change. They sequester and store large quantities of carbon in both the plants and the sediment below. Conservation and restoration of coastal ecosystems has the potential to help mitigate climate change while supporting many countries’ adaptation efforts and contributing to their sustainable development goals. 

Coastal ecosystems such as mangroves, tidal marshes and seagrasses play a significant role as carbon sinks in the fight against climate change. They sequester and store large quantities of carbon in both the plants and the sediment below. Mangroves, for example, store three to five times more carbon per area than many terrestrial forests.

Conservation and restoration of coastal ecosystems has the potential to help mitigate climate change while supporting many countries’ adaptation efforts and contributing to their sustainable development goals. Yet, too often they are destroyed to make way for development, or for the exploitation of resources, and are excluded from future planning.

Destruction of these ecosystems results in the release of carbon back into the atmosphere, further fuelling climate change. It is estimated that more than 1 billion tons of carbon dioxide are released annually from degraded coastal ecosystems - more than the emissions of the UK, France and Italy combined.

Resilient to natural hazards, they also contribute to disaster risk reduction, providing coastal protection against floods, storms, tsunamis and sea level rise.

Coastal ecosystems have a critical role to play in helping us mitigate and adapt to climate change, making it all the more urgent that we act now to protect and restore these ecosystems and increase marine protected areas.

And what is blue carbon? It is the carbon stored in coastal and marine ecosystems – taken from the atmosphere and oceans and stored as "blue" carbon.

IUCN is working with many partners and members on sustainable coastal management around the world. Some of the key initiatives that have helped propel international action on blue carbon can be found in the full article here: https://digital.iucn.org/marine/blue-carbon/

Report: Blue Infrastructure Finance, where all win

16 Apr 2020 - All coastal and marine ecosystems are critical to human well-being and global biodiversity. Mangroves, coral reefs, and seagrass beds are examples of these.

16 Apr 2020 - All coastal and marine ecosystems are critical to human well-being and global biodiversity. Mangroves, coral reefs, and seagrass beds are examples of these. But urban and rural infrastructure investments are having a heavy negative impact on these sytems, and it is increasing over time.

To find out how to turn this around, IUCN brought together a group of leading experts – with finance, conservation and engineering backgrounds – to explore how infrastructure finance and Nature-based Solutions (NbS) can work hand in hand to make infrastructure investments better, more durable, and financially more attractive.

For a turnaround to happen, developers, policy makers, and financiers must be familiar with blue infrastructure in coastal areas. One of the key objectives of this report is to enable all these important groups to answer at least three questions:

  • What is NbS?
  • What are resilience-planning approaches?
  • What are means for obtaining blue infrastructure finance?

Answering these questions will allow blue solutions to win for all involved, from the developers to the policy-makers and financiers, to the local communities, and finally to the biodiversity on which we all depend.
