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.

Addressing 21st century development challenges requires investments in innovation, including the use of new approaches and technologies.

Despite the potential of AE/O, their full benefits cannot be realised in most countries due to political and institutional barriers and lock-ins, including incentives and funding that favour "business as usual" food systems. Overcoming present and future challenges will require educated and empowered stakeholders to support AE/O agriculture in their fields.
