<s>[INST] The next text is a question of a member of the European parliament:"More than 50 % of the field margins in my constituency (the South West of England) are over two metres. The Commission and the Court of Auditors have recently instructed MAFF to reduce the amount of subsidies given to farmers whose field margins are over two metres. If farmers in the south-west do not wish to lose an average of £ 969 per year, they will have to plough right up to, and possibly cut back, their hedges. This will damage wildlife and remove land vital for preventing soil erosion on steep fields. It will run counter to the environmental goals adopted by the EU.  The UK has asked the Commission to increase the """"""""set-aside"""""""" margin to three metres for the UK. In the interests of promoting environmental conservation, will the Commission agree to rethink its approach, at least in the case of farmers who have traditionally maintained wide field margins?"
