Hello fellow Critters

I'd be very grateful if people could send me suggestions for who is writing the best stuff about agri-environment schemes/high nature value farming and rural policy at the moment. I am working in England - so particularly interested in work from/about here - but also interested to hear about the rest of Europe and wider.

Academic research of interest, but also suggestions for grey literature and good commentators very welcome. 

Many thanks in advance, 
Beth
