About Ag.Impact

Enhancing the impact of agricultural research

The Centre for Agricultural Research Impact, or Ag.Impact, is a UK not-for-profit dedicated to enhancing the impact of agricultural research.

We work with research institutions and funders to help them make grounded, open and strategic decisions. We do this by convening and advising those involved in agricultural research and generating evidence to inform their decisions.

Ag.Impact launched in 2025, spinning out from the Centre for Effective Innovation in Agriculture (CEIA), a partnership of five universities.

Our work is supported by the Elizabeth Creak Charitable Trust, which previously funded CEIA.

Our team.

Although we have just launched Ag.Impact, our team has worked together to strengthen the public benefit of agricultural research for far longer.

Through CEIA, we supported members of the Agricultural Universities Council to develop their first joint research strategy. We also supported Defra’s development of the ADOPT funding programme for farmer-led innovation. This drew on our previous experiences establishing the Innovative Farmers network, in turn informed by work on agricultural research governance dating back over 20 years.
