The International Partnership for the Satoyama Initiative (IPSI) is a global network to promote collective efforts for sustainability in socio-ecological production landscapes and seascapes (SEPLS), and thereby to contribute to the realisation of “living in harmony with nature”. The Satoyama Development Mechanism (SDM) is a seed funding programme that supports selected projects proposed by IPSI members. This report centred on the way and the extent to which the SDM projects contributed to the IPSI Strategic Objectives, and to the Aichi Biodiversity Targets (ABTs) and the Sustainable Development Goals (SDGs). We further explored the possibility that the SDM projects were likely to induce transformative change, with particular focus on the policy uptake of the project outputs, the mobilisation of additional investments, partnership building and outreach. In addition, the report provides the results of a self-assessment of the performance of the SDM Secretariat.
