Opening the DEFRA treasure trove will create opportunities for new types of applications in
agri-tech, says expert adviser

3D visualisations of landscapes, real time data on water quality and levels, market data on stocks of cereals held on farms and usage of cereals by maltsters – these are just some of the diversity of data to be made available by the Department for Environment, Food and Rural Affairs (DEFRA) in June, creating potential for new business models.
DEFRA's transition to becoming a department that is 'open by default' will unlock a treasure trove of data with agricultural potential. Ellen Broad, Expert Adviser to the Secretary of State, says: "Over the course of this next six months, DEFRA will be releasing more data to do with things like groundwater and waterways, erosion, animal movements and plants, all of which could have exciting potential. Because all of these datasets are openly licensed, they're free for agricultural companies to access, use and share for their own purposes."

Agriculture in other European countries are benefiting from open data. In the Netherlands, the Boer & Bunder project has aggregated information about cropping, soil types, and crop cover (using NDVI*) to individual fields units using geo-positioned land parcel data. The portal uses historic data obtained from 1.9 million hectares of farmland over the last six years.

Robert Allen, Technical Manager at Greenvale AP, says knowing the history of the land is invaluable when assessing its potential.

"The increase of contract farming and land rentals make understanding field history and rotation increasingly challenging, as fields could be cultivated by a different grower each year. Open access to rotational history data, like the Boer & Bunder platform, would allow land renters and owners to ensure good rotational practices are maintained."

The aim of the Boer & Bunder project is to demonstrate how open data is a useful tool for growers, and to create a platform to generate ideas as to how data can be exploited, leading to new products and services.

Last year the Environment Agency released data collected by one of the most advanced visualising systems. The process LIDAR (Light Detection And Ranging) uses a laser to scan and map the landscape from above and is widely considered to be the best method for collecting very dense and accurate elevation data across the landscape.

LIDAR data has been used to help the work of the Environment Agency, creating flood models, assessing coastal change and analysing how land is used, and it is now available for wider use.

Ellen Broad continues: "Already we've seen the release of key datasets like the LIDAR 3D height data being picked up and used for a range of external purposes, by national parks, urban planners, agricultural data companies, even gamers! This shows the range of potential applications for this data. "
