This panel session will engage all participants in a discussion about the challenges of intensifying cool temperate agriculture, and the potential for agricultural systems research to address these challenges.

The scene for a 45 minute discussion will be set by four 10 minute presentations from global, regional and local perspectives.

It builds on field trip 3 – The Midlands.
