The growing demand for agriculture-related NCOs has rendered the market failure related to its provision into a relevant issue for policy makers. This was clearly illustrated, in 1992, by the extension of the EC agri-environmental schemes to all Member States. These schemes remunerated farmers for the environmental and landscape management services they provide for free to society. Hence, these payments exemplify the interest of pricing non-market agriculture-related good and services. If monetary estimates for their value to consumers (demand-side) are available then payments for their provision could be made according to demand.
