CAP reforms, from the Nineties to Mid Term Review, aim to start important structural measures, that improve relationship between agriculture and environment. In this context the multifunctionality in agriculture seems to be a condition to produce environmental and landscape externalities, but there are not many studies about positive externalities analysis and evaluation. This paper regards agriculture landscapes, that have aesthetic, ecological and cultural value. The authors present some results of the national research "Landscape-environmental measures in rural development regional policies". They particularly examine critically the components of integration and interaction among different dimensions of landscape actions: the dimension concerning the territorial and local planning, the one about the economic instruments of policy (effectiveness and efficiency in agri-environmental measures), the other about the evaluation (monetary and not).
