Scaling up the adoption of EbA solutions using behaviour-centred design: The case of Vetiver grass for riverbank erosion control in Fiji

Implemented by the International Institute for Sustainable Development (IISD) and Rare


EbA, like other climate solutions, requires substantial human behavioural changes. But so far, the role and implications of behaviour change have largely been overlooked, oversimplified, or incomplete. A more nuanced understanding of the determinants of human behaviour – and the role of behavioural change – in supporting the scaling up of climate adaptation solutions and the implications for developing and implementing ambitious climate policies is needed. Using a pilot case of the adoption of Vetiver grass for riverbank rehabilitation to reduce damages from floods in Fiji, this project aims to understand how to design behaviourally informed EbA solutions and the differences it can bring for scaling up actions. The implementation of a pilot approach in a vulnerable river catchment in Fiji – as well as the development of policy recommendations to incentivise the uptake of EbA in Fiji – strengthens the evidence base for applying behavioural analysis in the implementation and scaling up of EbA solutions. Insights gained from the project should inform the design and implementation of other ongoing and future EbA programs and related policies in Fiji and beyond.
