Participatory Guarantee Systems Toolkit

This toolkit is aimed at anyone working to build local food systems as it addresses solidarity based initiatives such as Community Supported Agriculture (CSA) and Participatory Guarantee Systems (PGS).


PGS and CSA are similar in their overall objectives of improving livelihoods of organic producers and increasing access to safe and nutritious food for consumers. Both PGS and CSA enhance transparency and shared decision-making processes, prioritizing a solidarity approach where the responsibilities for implementing sustainable agriculture practices are shared by the community.


The toolkit is composed of a series of tools:


"PGS Guidelines. How to develop and manage Participatory Guarantee Systems for Organic Agriculture"

These guidelines make the cornerstone of the toolkit. They highlight how, although developed independently in different countries and cultural contexts, PGS initiatives around the world share a common set of key elements and features. This revised edition of the PGS guidelines also propose a step by step approach for implementing PGS and introduce other important concepts like marketing and organisational arrangement.

"Policy Brief: How Governments can Support Participatory Guarantee Systems (PGS)"

 Published for the first time in 2011, this Policy Brief on PGS is a landmark in IFOAM’s advocacy work. The document targets policy makers and advocates that wish to support PGS not only through recognition in their national organic regulatory systems, but also through different form of support aiming at promoting rather than regulating. For additional tips on how to ensure public support to PGS development you can check the dedicated section of the Guidelines for public support to organic agriculture.

Template Checklist for Peer Reviews for Crop Production

The peer review provides a mechanism through which compliance to the standards and norms can be verified by peers. It also provides for knowledge exchange whereby all involved parties learn more about the standards and each other’s farming practices. Users are encouraged get inspiration and adapt the content of this checklist according to their needs. Designing, testing and adopting the right peer review based on  the standards adopted is a fundamental step for every PGS initiative and for those CSA initiatives introducing farm visits in their everyday activities. This checklist comes together with a basic list of objectives and requirements that should be addressed in each organic standards, with a focus on crop production. This list is taken from the COROS (Common Objectives and Requirements for Organic Standards - also called “IFOAM Standards Requirements”).    




"Synergies between Community-Supported Agriculture (CSA) and Participatory Guarantee Systems (PGS)"

Usually, CSAs are implemented through a strong partnership between one or several producers and a group of consumers who pay upfront to receive a share of the harvest. This publication, produced by URGENCI and Miramap, analyses needs and benefits that motivate CSA groups to include a PGS in their  structures. The reasons span from the necessity of  preserving the meaning of the CSA concept (i.e. with respect to the founding principles of CSA) to continuously improve the agricultural practices and the solidarity partnership.

PGS Brochure

The PGS Brochure

The PGS Brochure explains what the key elements and features of PGS are. The diversity of organic agriculture and guarantee systems, among which PGS, is highlighted. This Brochure is available in different languages: English, French, Spanish, Portuguese, Italian, German, Albanian, Japanese.




A direct witness from Christophe Nothomb, ex coordinator of the PGS program of the CSA initiative GASAP (link is external)(Belgium). This organisation of producers and consumers has started since 2016 to experiment with PGS and the initiative is now fully operational. Learn how they started to set up and pilot their system.








Case Study

Showcases the needs and benefits for French CSAs to include formalised farm visits to better structure the partnership between consumers and producers and improve practices such as breaking free from chemical inputs dependence. The case study focuses on the experience of the Basque Country CSA network and was produced by Miramap



Global Comparative PGS Case Study 

The study shows that PGS is an important platform for the development of these social processes that in turn positively impact PGS initiatives in different ways, thereby improving the sustainability and impacts of the PGS. It finds that PGS has the potential to make a significant contribution to the reduction of food insecurity and to improved nutrition among farmers in rural areas.
