An octopus's garden

The octopus is prized as the most intelligent of all marine species – immortalised in stories, poems and songs worldwide. In Madagascar it is also a vital source of income. Hazel Healy takes a journey into a pioneering Madagascan closure system which is enabling one particular species of octopus to flourish and protecting incomes for the most vulnerable. She learns how the system was first developed and how it is inspiring other coastal communities in Kenya and Indonesia. Hazel also learns how the success of the system has sparked greater support for ambitious marine management efforts more widely, including the creation of permanent marine reserves in Madagascar.
