Environmental importance: The coast and its adjacent areas on and off shore are an important part of a local ecosystem: the mixture of fresh water and salt water in estuaries provides many nutrients for marine life. Salt marshes and beaches also support a diversity of plants, animals and insects crucial to the food chain.

The high level of biodiversity creates a high level of biological activity, which has attracted human activity for thousands of years. W

Sea level rise: Sea level rises can considerably influence human populations in coastal and island regions and natural environments like marine ecosystems. Sea level rise is expected to continue for centuries. Because of the slow inertia – long response time for parts of the climate system, it has been estimated that we are already committed to a sea-level rise of approximately 2.3 meters for each degree of temperature rise within the next 2,000 years.

Coastal Cities' Futures Depend on Today’s Climate Decisions
Authors: climatecentral, Oct 12, 2021

Societies can adapt to sea level rise in three different ways: implement managed retreat, accommodate coastal change, or protect against sea level rise through hard-construction practices like seawalls or soft approaches such as dune rehabilitation and beach nourishment. Sometimes these adaptation strategies go hand in hand, but at other times choices have to be made among different strategies. For some human environments, such as so called sinking cities, adaptation to sea level rise may be compounded by other environmental issues such as subsidence. Natural ecosystems typically adapt to rising sea levels by moving inland; however, they might not always be able to do so, due to natural or artificial barriers. W

Blue Ventures is a registered charity focused on nurturing locally led marine conservation. The organisation partners with coastal communities that depend on marine resources.

Blue Ventures' marine management models aim to combine community-led resource management, community health, and alternative livelihood initiatives for the benefit of both the people and the environment.

The organisation operates in the Indian Ocean, Southeast Asia, and the Caribbean. Blue Ventures implements its own field programs in Madagascar, Belize, Indonesia, and Timor-Leste, and has small staffs in Comoros, Kenya, Mozambique, and Tanzania to support partners' projects.

Coral Reef Alliance

Headquartered in Oakland, California with field offices in Hawai‘i, Fiji, Indonesia and Honduras, CORAL unites communities to save coral reefs. Working with local people, communities, and partners—from fishermen and government leaders to divers to scientists—CORAL protects one of our most valuable and threatened ecosystems. International teams design long-term and lasting conservation programs that reduce local threats to coral reefs and are replicated across the globe.[1]

Citizens data initiative[edit | edit source]

Research shows that 634 million people - one tenth of the global population - live in coastal areas that lie within just ten metres above sea level.[2]
