Participatory Guarantee Systems (PGS) and short organic supply chains have emerged as promising solutions for smallholder farmers to provide organic produce to nearby consumers. PGS is an institutional innovation that builds trust among producers, traders and consumers through a low-cost transparent and participatory certification mechanism. They have particularly gained a foothold among smallholder farmers in middle- income countries, where third-party certification costs are often unaffordable.

Innovation portfolio management enables not only commercial actors but also public sector organisations to systematically manage and prioritise innovation activities according to concurrent and diverse purposes and priorities. It is a core component of a comprehensive approach to innovation management and a condition to assess the social return of investment across an entire portfolio. The OECD Observatory of Public Sector Innovation (OPSI) has worked in this space for a number of years.

The OECD Mission Action Lab critically examines the practice of missions and mission-oriented policies as well as their suitability to different problem contexts. Addressing complex challenges comes first, methods come second. The Lab is, thus, not promoting "missions" as the one and only instrument to address complex problems or societal transitions. Rather, we aim to understand when and how mission as an approach to public policies is useful and, sometimes more importantly, when it is not.

Despite the concept's widespread popularity, the terminology surrounding missions can come across as convoluted. This is understandable, given that the term - which denotes ambitious, time bound, cross-sectoral and measurable policy objectives to address grand societal challenges such as climate change mitigation, biosphere restoration or tackling health inequities - has proven to be both deceptively intricate and remarkably versatile.
