Can new technology solve labour shortages in farming?

There is considerable interest in the potential of new technology for making farming more productive and less reliant on difficult to obtain labour. I think that the development and application of these technologies should form a key part of a domestic agricultural policy post Brexit, but no one should pretend that they offer a quick, readily available and affordable fix.

Big farms already use semi-autonomous satellite-guided tractors and combines, which can drive in straight lines without overlapping. However, these big machines also tend to compact the soil, affecting its long-term viability and plant growth.

Harper Adams University, using government funding from Innovate UK, have adopted machinery to drill, spray and harvest crops autonomously using open source software, cameras, lasers and sensors. They used drones and scout vehicles to monitor the field and collect data by bringing back soils and crop samples.

The first crop is slightly wobbly where the tractor failed to keep to its line. The first hands free crop is expected to yield only 4.5 tonnes per hectare, compared with 6.8 tonnes using conventional methods.

In the horticulture sector, where labour problems are particularly acute, machines to pick strawberries and apples are being deployed, but they pick at only one third of the rate of a human and miss 15 per cent of the crop. Moreover, the machines can cost something approaching £200,000. Most farmers reckon that their large scale deployment is at least a decade off.

However, it is clear that one narrative that is being put forward (see Matt Ridley in The Times today is that access to cheap labour has held back the introduction of new technology in British farming.

The deputy president of the NFU has told a meeting at the Liberal Democrat conference that future growth in agriculture will be driven by overseas labour. There was no sign of government action on labour and trade issues: Lack of action

Lib Dems lack say in farm policy-making

Defra is just one of three government departments that does not include a Lib Dem minister. Moreover, all the ministers in the department have strong farming links, inclining them towards a productionist agenda.

Lib Dem farm spokesman Andrew George, the MP for West Cornwall and the Isles of Scilly, has criticised the Conservative stranglehold on posts. Differences have emerged on the proposed badger cull and the decision to abolish the Agricultural Wages Board.

Mr George has been trying to work with the Secretary of State, Caroline Spelman, to have some say about how budget cuts are made. However, he has admitted that he was 'not yet in the inner circle of Defra ministers'.

Most disagreements are likely to be over matters of domestic policy such as the two that arisen already, rather than attitudes towards the CAP where both parties share a relatively liberal, market oriented stance. However, the Lib Dems are particularly attuned to the concerns of smaller farmers from whom they receive electoral support.

Spel(l)ing it out

New Defra supremo Caroline Spelman went down well at her first Farm Council as she has a fluent command of French and German which facilitated informal discussions with ministers. She has built up informal links with German agriculture minister Isle Aigner on the issue of lighter regulation and is planning a bilateral meeting with French minister Bruno le Maire.

She is taking a relatively reformist stance on CAP, noting that there are four constituencies to be satisfied. She told Farmers Weekly 'Farmers need a good deal from CAP reform. So, too, do consumers, taxpayers and the environment. It is a four-pronged approach to how we reform the CAP.'

Rumours have been circulating that Defra will be abolished or rebadged and substantially restructured. However, the minister said: 'I am not a huge fan of big structural change. In my experience, messing around with structures can end up costing money as well as saving money. It is not my top priority.'

Reading the farming press one gets the sense that farmers have realised that it is not bonanza time, particularly given the fiscal constraints. Cost and responsibility sharing on animal health is still very much on the agenda and the commitment on a bovine TB cull is very qualified.

All four Defra ministers have strong farming connections which is how the Conservatives tend to recruit their ministers and there are no Lib Dems in the department, somewhat surprising given their rural focus. However, this is not necessarily a MAFF (Ministry of Agriculture) in all but name. As far as CAP reform is concerned, the personnel may have changed, but British interests in value for money have not. Indeed, they are likely to be emphasised even more.
