World Wetlands Day, marked on February 2 — the day on which the Convention on Wetlands was adopted in Ramsar, Iran, in 1971 — is an annual acknowledgement of the importance of wetlands to life and sustainability on our planet. The 2022 theme focuses on a call to action through behaviour, activism, monetary investment, and political support, to ensure that the world's precious and vulnerable wetland ecosystems are restored and protected from further degradation. Although wetlands cover less than 10 per cent of the earth’s surface, a whopping 40 per cent of all plant and animal species live or breed there. Quite apart from being a food source for humans and animals, wetlands are crucial to climate balance, as they contribute to water regulation, filtering and flood management. In Small Island Developing States (SIDS) like the Caribbean, which are at the receiving end of the worst impacts of climate change, wetlands are integral to the fight against global warming by stabilising greenhouse gas emissions and storing carbon within their biomass and soil (carbon sinks). This despite the fact that climate change has already brought with it negative side effects, including decreased levels of fresh water, deforestation and sea-level rise. Unfortunately, many regional wetland areas, like the mangrove forests in Trinidad and Tobago at the southern end of the archipelago, are threatened by pollution and sargassum, the proliferation of which has been linked to warmer ocean temperatures as a result of climate change. Trindad's Pointe-a-Pierre Wildfowl Trust, one of the country's best known wetlands defenders, posted images on its Facebook page in celebration of World Wetlands Day, even as it pledged to continue “the conservation and preservation of Wetlands and all their inhabitants.” Another Trinidad-based NGO, SpeSeas, tweeted: As part of #WorldWetlandsDay, we would like to draw attention to sustainable use of our very own wetlands, the Nariva Swamp, Caroni Swamp & Buccoo Reef/ Bon Accord Lagoon complex and encourage their protection and conservation efforts pic.twitter.com/Y8okrVVkbL — SpeSeas (@SpeSeas) February 2, 2022 Marine biologist Jahson B. Alemu I added: This #wetlandsday I've been thinking a lot about the awareness-action gap & what I can do better to #ActForWetlands and #climatechange. I think for starters I'd like to build more inclusive narratives around OUR identity & wetlands. Happy wetlands day #rewet #reforest #restore — Jahson B. Alemu I, Ph.D (@jahson_alemu) February 2, 2022 In addition to their functionality, wetlands are also quite beautiful. In honour of World Wetlands Day, here's a glimpse of a few of the Caribbean's most breathtaking wetlands, starting from Guyana on the mainland and moving north up the island chain.

In addition to taking in and rehabilitating injured birds, the Pointe-a-Pierre Wild Fowl Trust does a lot of research, advocacy and education outreach about the environment in general and wetlands in particular.

With its substantial estuarine mangrove system, the Caroni Swamp, which borders the Gulf of Paria on Trinidad's western coast, is one of the island's two designated Ramsar sites. The second is the mainly freshwater Nariva Swamp, located on the eastern coast. (Tobago's Buccoo Reef is the country's third Ramsar site.) Not only do wetlands like these purify water and protect the coastline from erosion, as well as the ill effects of storms and flooding, they are also wonderful locations for eco-tourism and environmental education.

This picturesque lagoon, located within the Tobago Plantations resort, has a thick area of mangrove through which a boardwalk has been constructed above the mangrove roots. The lagoon itself is a mix of fresh and salt water. The Graeme Hall Nature Sanctuary contains the last major mangrove wetland in Barbados. A staging point for thousands of migratory birds, it was closed in 2019 due to a dispute with the Barbados government. Photo by David Stanley on Flickr, CC BY 2.0.
