Mangroves are vital ecosystems that provide coastal protection against storms and erosion, filter water, store vast amounts of carbon to combat climate change, and serve as critical nurseries for marine life, supporting fisheries and biodiversity.
They also offer significant economic benefits, including a source of food, medicine, and building materials for coastal communities.
Despite the numerous benefits, Ghana’s illegal mining and uncontrolled plastic wastes are significantly impacting mangroves in Ghana’s marine ecosystem.
The Illegal Mining Effect
Illegal mining, also known as galamsey, is polluting water bodies and degrading mangrove ecosystems. This activity involves the use of hazardous chemicals like mercury and cyanide, which contaminate water sources and harm aquatic life.
Such mining operations often lead to the destruction of mangrove habitats, causing loss of biodiversity and disrupting the ecosystem.
Mercury levels in water bodies affected by illegal mining exceed safe thresholds, posing health risks to humans and marine life.
Plastic Waste
In recent times, plastic waste is entering Ghana’s ecosystems, including mangrove habitats, causing harm to the environment and wildlife. Mangroves can trap plastics and sediments, but excessive plastic pollution can still harm the ecosystem.
Plastic pollution, combined with overfishing and habitat destruction, is depleting fisheries and affecting the livelihoods of fishing communities
Conservation Efforts
Many non-governmental organizations and fragmented governmental initiatives are currently running to help in mangrove restoration. Initiatives like the Mangrove Blue Carbon Pilot Program aim to restore mangrove forests, promote sustainable livelihoods, and mitigate climate change.
Among major actors in the mangrove restoration effort is ‘Hen Mpoano’ (meaning “Our Coast” in Akan) is a Ghanaian non-governmental organization dedicated to sustainable management of coastal and marine ecosystems. Based in Takoradi, Western Region, they’ve been working since 2013 to promote inclusive and integrated management of coastal resources.
Hen Mpoano focuses on restoring degraded mangrove ecosystems, promoting vegetation, and marine life through education and community engagement. They’re currently working on planting 200,000 mangrove seedlings in Ghana’s Greater Amanzule Wetlands.
The organization designs and implements sustainable livelihood interventions to reduce poverty and food insecurity in coastal communities.
Hen Mpoano engages with policymakers to advocate for policies promoting sustainable use of coastal and marine resources.
Hen Mpoano’s efforts aim to benefit approximately two million people in Ghana who depend on coastal ecosystems for their livelihood by promoting sustainable management of coastal resources; the organization contributes to Ghana’s commitment to restore 1.7 million hectares through tree planting by 2030.
