On-Farm Experimentation: a global movement to accelerate the transformation of agriculture

PRESS RELEASE - A new generation of on-farm experimental activities, co-created with farmers, is opening up alternative innovation pathways in agriculture. An international team of researchers from 9 countries (Argentina, Australia, Canada, China, France, Malaysia, Morocco, the United Kingdom and the United States) has been formed to establish the fundamental principles of the OFE (On-Farm Experimentation) movement and to make the case for its formal recognition and support. The team, whose members in France include INRAE and the #DigitAg Institute, published its conclusions this December in Nature Food. The team demonstrate that the OFE collaborative learning model, which is gaining global momentum, could boost the agroecological and digital transitions in agriculture.

Experimenting on farm has been part of the research toolkit for nearly two centuries and is now being reinvented as part of a growing shift towards open innovation practices. An international team of scientists has come together to explain how On-Farm Experimentation, or “OFE”, has attracted participants around the world and why the approach differs from previous research practices, arguing that it has the capacity to transform agriculture.

Over 30,000 farms are involved in OFE: what are the principles behind it?

OFE embeds experimental research within the real-world activities of individual farms through mutually beneficial collaborations between farmers, researchers and other members of the agri-food sector. In practice, OFE initiatives take the form of a step-by-step process in which the farmer and scientist define together an investigation’s terms of reference and set up experiments that are tailored to the particular circumstances of the farm.

The team reported on experiences gained from 11 OFE initiatives around the world and estimated that over 30,000 farms are involved in OFE, even though the approach has not yet been formalised and has only rarely received institutional support in a systematic way.

Despite the sheer diversity of goals, approaches, sociotechnical ecosystems and geographical locations involved, the team was able to identify six guiding principles for OFE:

  • Real systems – experiments are conducted on farm and are embedded in farm management;
  • Farmer-centric – experiments are driven by the farmer’s questions and are performed collaboratively involving, as a minimum, both farmer and scientists;
  • Evidence-driven – experiments are based on the analysis of farm-specific data, which may be facilitated (though not dictated) by digital technologies;
  • Specialist-enabled – experiments draw on the contributions of external experts, making it possible for new tools to be introduced and varied viewpoints to be considered;
  • Co-learning – experiments are built around ongoing discussion between the participants who, in designing and carrying out the experiments jointly, share their visions and experiences, learning from each other and further developing ideas together;
  • Scalable – experiments create knowledge that is valuable locally for individuals, and that is also intended to stimulate broader insights.

A pragmatic mechanism to foster locally-relevant knowledge and renew research questions

As we engage in transitions for our agricultural systems through agroecology, data technology, food, One Health etc., it is important to establish a better understanding of the transformational potential of OFE, whose principles incorporate those of open innovation.

Many approaches, past and present, have used frameworks similar to that of OFE, notably farmer-participatory research. What distinguishes OFE is the value it creates for each participant: farmers can explore practices directly related to their own farming needs, while researchers gain access to field data and informal knowledge that enrich their research and open up new pathways. Different knowledge types – produced not only by scientists and farmers but also by advisors and other industry partners – are jointly put to work, making OFE a pragmatic mechanism to accelerate the creation of locally-relevant and directly applicable knowledge.

In France, OFE can be seen in operation in the DEPHY farm network, with nearly 3000 farmers working to test out pathways for the reduction of pesticide use in partnership with expert advisors and researchers. Another project, the Occitanum Living Lab, was recently set up in the Occitanie Region. Coordinated by INRAE and involving 48 partners, Occitanum supports farmers in testing digital technologies and helps them to work in partnership with researchers to assess their economic, environmental and social performance.

The six OFE principles bring into focus the profound changes that have occurred in the ways agricultural experimentation is conducted. Not just a tool to validate lab-based theories, experimentation is becoming a genuine method to stimulate the production of local and applied knowledge. The process renews research questions: how do we hybridise plural knowledge (formal, informal, local, generalisable, data-mined)? What is the nature of the data that supports the construction of knowledge? How do we measure the value it creates, and distribute this value fairly? To address these questions and to boost the fundamental transformational changes that agricultural systems need, the team argue that the OFE movement and its community must be supported and strengthened.


OFE2021, the first international conference on OFE initiatives, was organised in October 2021 in Montpellier by INRAE’s #DigitAg Institute and the ISPA (International Society for Precision Agriculture), with a focus on digital technologies. It provided a forum for the 170 participants from 36 countries to engage in wide-ranging discussions on OFE, exploring value creation, data analysis, innovation ecosystems and public policies that put farmers at the heart of agricultural innovation.

H2020 IPMWorks: reducing pesticide use by building a European farm network based on the French DEPHY model

PRESS RELEASE - Reducing pesticide use 50% by 2030 is the goal of the European Union's Green Deal and Farm to Fork strategy. Throughout Europe, agricultural policies have prioritised engaging with farmers, whose commitment is essential in the quest to change agricultural practices. Drawing upon the experiences of the French farm network DEPHY, the H2020 IPMWORKS project will build a European farm network with a two-fold objective: to demonstrate integrated pest management (IPM) strategies, which use small quantities of pesticides, and to promote the adoption of such strategies via knowledge exchange and peer-to-peer learning among farmers. IPMWORKS was officially launched in the autumn of 2020 and will run for a period of 4 years. The project is coordinated by INRAE and has brought together 31 partners in 16 European countries. These partners include ACTA, the network of French agricultural technical institutes, and APCA, the assembly of French chambers of agriculture.

LACCAVE: a ten-year research partnership to adapt viticulture to climate change

PRESS RELEASE - LACCAVE, a ten-year research project on the adaptation of viticulture to climate change, is coming to an end. Initiated in 2012, the project involved some 100 researchers to study conditions in which the French wine industry can be adapted to climate change. It was financed and coordinated by INRAE, and carried out in partnership with the CNRS, several French universities, including Montpellier SupAgro and Bordeaux Sciences Agro agronomy schools, as well as the major professional organizations in the sector: the INAO, FranceAgrimer, the Chambers of Agriculture, the IFV, and interprofessional and appellation unions. LACCAVE was officially brought to a close in Montpellier with a scientific seminar (24-26 November) and a series of conferences and participatory workshops at the SITEVI agricultural trade fair (30 November-2 December). The findings of the researchers in attendance underline the fact that the impacts of climate change on vineyards are increasing. Nevertheless, solutions for adaptation are available if average temperature increases are contained to less than 2°C and if the joint mobilisation of the industry, public authorities and research continues.

Agroecological transitions, between determinist and open-ended visions

Debates around agroecology most often focus on the depth and radicality of the change and relate to different visions of agroecology, which tends to eclipse the ontological relationships of actors (or researchers) to the very 'change process' itself. This book is an endeavor to explain relationships to change in agroecological transitions, referring to two contrasting and ideal-typical ontological relationships to change, the determinist perspective and the open-ended perspective. Many diverse cases of agroecological transitions are discussed, in order to highlight the fact that these perspectives are not always exclusive in transition process but that they can be articulated successively or combined complementarily
