Coastal ecosystems worldwide support an estimated 80% of the global annual fish catch and provide an estimated US$12 trillion in socio-economic benefits known as “ecosystem services,” so it’s vital to understand how their characteristics influence how they are changing.
Engineers from UNSW Sydney have designed and built a system that biomimics tides to help restore vital coastal wetlands.
Over the last decades scientists have discovered that seagrass meadows, tidal marshes, and mangroves – “blue carbon” ecosystems – are among the most intensive carbon sinks in the biosphere. By sequestering and storing significant amounts of carbon from the atmosphere and ocean, blue carbon ecosystems help mitigate climate change. But conversion and degradation of these ecosystems can also release billions of tons of CO2 and other greenhouse gases into the ocean and atmosphere and contribute to global warming.
Protecting areas of ocean from destructive human activity could help prevent climate change, protect biodiversity, and at the same time increase the catch of fish, according to the most comprehensive analysis of its kind.
In recent times, communities in the Western Province of Solomon Islands have seen a drastic decrease in fish numbers in their common fishing grounds. Two coastal communities that rely on the ocean for survival are Nusa Baruku, on Gizo Island, and Babanga...The communities need assistance fro
Trees lost to drought and wildfires are not returning.
The climate crisis is pushing the planet’s tropical regions towards the limits of human livability, with rising heat and humidity threatening to plunge much of the world’s population into potentially lethal conditions, new research has found.
Oceans around the world face a litany of threats, from climate change to overfishing to pollution and more.
Flooding and erosion are growing problems for low lying coastal zones across the world. These phenomena are expected to worsen globally by 2-3 orders of magnitude by 2100.
Communities living close to hard-bottomed shallow shore are more likely to catch animals for seafood consumption in the rough season when other types of fishing often aren’t possible, a new study has found...The authors say that understanding the interactions between people and coastal ecosystems
