Current Situation

Mafia Island is Tanzania’s most important sea turtle nesting site. More than 250 green turtle nests are laid there each year and the critically endangered hawksbill turtle is also known to nest on the tiny islands around Mafia. However, nesting beaches are on the east coast of the island and are continually covered in large amounts of plastic waste that washes in on the east African current from as far away as Indonesia and the Philippines. The amount of plastic debris on the nesting beaches poses a significant threat to nesting sea turtles and emerging hatchlings and also threatens the long term sustainability of a developing sea turtle ecotourism project.

Sea Sense has organised a number of beach clean-up events in Mafia Island and delivers an ongoing waste management education programme to communities. However, plastic debris is constantly washed up with every incoming tide and hence it is necessary to develop a more creative and sustainable solution to the plastic problem on sea turtle nesting beaches in Mafia.
