New paradigm?

Current paradigm – New paradigmFarmer

•Cultivation•Theoretical base•Known properties

- Coverage- Non-response- Known and tested

variables•Skills well developed if in short supply•Infrastructure •Process•Security of supply of inputs

• Lacks statistical properties• Unknown coverage/bias• Doesn’t necessarily have the

measures you want/need• Lack of standardisation• Needs alternative theoretical

framework• Growing on someone else’s

land?• Future supply uncertain
