Their report, Enhancing Arable Biodiversity, published today after a five-year study, identifies six techniques, to encourage arable wildlife, that would help reverse the declines of species such as skylarks, yellow wagtails and yellowhammers.
The study, by the 21 farming, environment and research groups that form SAFFIE - Sustainable Arable Farming For an Improved Environment – says farm profits would not be affected provided the government gave farmers appropriate support.
James Clarke, SAFFIE Project Director, said: “More than 20 per cent of farmland is arable and half of that is used for autumn-sown crops, which means fields and margins in summer can be too dense for birds seeking nesting sites and food for their young.
“Winter cereals are important for food and biofuels. The measures suggested by the SAFFIE research could enhance farmland biodiversity and are compatible with modern arable farming. This is a real opportunity for the government to meet its targets for reversing the decline of farmland birds. It’s about providing bed and breakfast for farmland birds.”
Research for the £3.5 million SAFFIE project was carried out on 36 farms in England and Scotland.
It found that skylark plots – small bare patches in arable fields – together with strips of grasses and wild flowers on field edges, increased the numbers of some birds by between three and four fold.
Plant diversity and open spaces in these strips were important because they encouraged beetles, which are sought by birds as food for their young, and allowed birds access to them. Using an herbicide to control fast growing grasses allowed other plants, bees and butterflies to flourish.
Skylark plots were incorporated in the government’s environmental schemes two years ago but take-up has been low. The researchers, who included ADAS, the RSPB and the Crop Protection Association, believe changes to these schemes, based on SAFFIE findings, would prompt more farmers to take part.
James Clarke said: “We don’t want uniform fields or field margins and are not suggesting that all farmers should do the same thing. But we need a diversity of habitat and if we have that, we’ll have a wide variety of thriving wildlife.”
Jonathan Tipples, a farmer and the SAFFIE Project Chairman, said: “We set out to develop measures to encourage wildlife that would be acceptable to commercial farmers. Thanks to the hard work and good science of everyone involved in the project, we now have six practical ways to enhance biodiversity in winter cereals.”
Graham Wynne, RSPB Chief Executive, said: “Measures for wildlife can be used by farmers without harming a farm’s profits. The recommendations SAFFIE is making could make an enormous contribution to helping farmland species recover their numbers and making rural businesses more sustainable. We very much hope the government and Natural England will take these proposals on board.”
Anne Buckenham, Policy Director, Crop Protection Association, said: “This is an outstanding example of Government, scientists, NGOs, levy payers and industry working together successfully to develop solutions for the benefit of biodiversity whilst maintaining crop yields. Farmers can receive £30/ha from environmental schemes. We now need to make sure the opportunities SAFFIE has developed are incorporated in the forthcoming review of environmental stewardship schemes.”
Dr Ann Davies, Defra - Head of Policy for Entry Level Stewardship, said: “This type of research is fundamental to the on-going development of Environmental Stewardship and the SAFFIE recommendations will help us make evidence-based decisions about changes to the Scheme.”

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
