Tropical wetlands — long seen as the reservoirs of much of the world’s biodiversity — are dangerously in decline. Anthropogenic medications and climate variability have resulted in the loss of key ecosystem services and functions. This is a quick peek into the tropical life of a rural fisherman who relies on tropical wetlands as a source of job.Read More
In a classic Tragedy of The Commons scenario, industrial fishing vessels in Ghana are dredging up small pelagics reserved for the artisanal sector — having already depleted higher trophic species.

Climate change is magnifying these vulnerabilities to the extent that fishermen no longer go to the sea because 'there is no fish in the ocean'. Is the future already here?
Fish processors in Ghana trade-off between their livelihoods and exposure to cancer-causing toxicants such as PAHs. Climate-related shocks, overfishing, and other human activities are also shaping the mobility of migrant fishers.
