Any change to land use should deliver long-term benefits, Lancaster said, and good productive land should be protected from "inappropriate use".
The council could help farmers by lobbying Government on such policy, Cameron said.
More processing and adding value to the district's agricultural produce would be good, Lancaster said.
Better broadband and better roads would be helpful on many levels, Street said — including for farm tourism, which was increasing.
He added that having revitalised towns would be attractive to young farmers and their partners.
All six agreed it was good for the district to have a diverse economic base and lots of social connections — both factors adding to its resilience.
