Economics of bio-digesters in the Solomon Islands

The Choiseul Integrated Climate Change Adaptation Programme (CHICCHAP) aims to reduce the vulnerability of the Lauru people of Solomon Islands to natural hazards, food insecurity and climate change threats. To support this aim, the Solomon Islands Government is trialling a swine manure
digester in Choiseul Province. The treated swine manure could be used to fertilise crops, while also providing biogas as an alternative to kerosene and firewood and reducing harmful run-off of pig waste. Drawing on an existing demonstration digester in Honiara, a study was conducted to examine the economic dimensions of adopting digesters in Choiseul.
