Project aims

The project aimed to produce an excel-based tool which can be used to assess the public goods provided on a farm. These are split into separate areas of public good:

  • Soil management,
  • Biodiversity,
  • Landscape and heritage,
  • Water management,
  • Manure management and nutrients,
  • Energy and carbon,
  • Food security,
  • Agricultural systems diversity,
  • Social capital,
  • Farm business resilience,
  • Animal health and welfare.

The tool provides a clear, easy-to-follow results page which a farmer can use to identify areas where there is potential for improvement and areas where the farm is above average.

ORC's role

ORC undertook the entire project.

Key achievements

The project developed the Public Goods Tool, which is a comprehensive sustainability assessment tool for farming systems. It offers a rapid and succinct overview of a farm’s performance, using a range of environmental, economic and social indicators. The tool can be used to identify areas for improvement and monitor changes over time. The assessment process is carried out with an advisor or researcher, with readily available sources of data being used to save time/avoid duplication of effort. The advisory focus of the tools facilitates a dialogue between the assessor and the farmer assessed. This allows for the identification of possible solutions to issues highlighted. The assessment process can also draw attention to the positive contributions a farm is making to society, above and beyond the food and other products leaving the farm gate.

Positive feedback from farmers and advisors involved in the pilot

“An assessment can really help give validity to what you’re doing and help you to focus on what you need to look at next or where there’s potential for doing something new”.

“It brings out stuff that is at the back of your mind to the forefront.”

“It has been a really useful exercise and I would encourage others to take advantage of it”

Next steps

A number of developments are planned for the coming years

  • The tool is also used within the SOLID research project to compare the performance of farms with regard to individual indicators (e.g. energy use or nutrients). See SOLID D11 report
  • We are working with the Swiss Research Institute of Organic Agriculture (FiBL), pooling our expertise to further develop methods for sustainability assessment and monitoring for organic farms.Ekhaga Sustainability Assessment
  • The use of the tools for Scottish conditions is currently explored by researchers from SRUC
  • Aberystwyth University will be involved in the use and development of the tool in Wales
  • The tool is being used within a TSB funded forage protein project that is working with Waitrose dairy, beef and lamb supply chains to encourage farmers to produce higher protein forage crops, reducing their reliance on external soya imports. More here
  • Development of system specific benchmarks for (organic and non-organic) farming systems, particularly with regard to nutrient budgeting and energy use
  • On-farm validation of the assessment results (e.g. through soil sampling, biodiversity assessment)
  • Weighting of the spurs included within the tool by location and/or farmer preference

Following the pilot, Defra commented that to make the tool as useful as possible in the wider farming context some of the questions should be modified to remove the focus on organic farms and to ensure that scoring is not weighted in favour of organic farming. ORC has undertaken to make the necessary modifications to the tool and now plans to carry out further testing of the tool on 35 conventional farms (spread across a range of farm types: cereals, dairy, general cropping, beef and sheep, mixed) in Spring 2014.
