Land consumption is currently one of the major problems affecting green spaces, natural or agricultural. This issue is very important both for agricultural system functionality and, consequently, for its permanence. This paper proposes an analyzing tool of land use changes to support planning policies, in order to highlight the major determinants of land use that affect the permanence of agricultural activity. The case studies are Lodi, Milan and Monza Brianza Provinces, in Lombardy Region. One of the most important results are that exogenous variables, like population density or real estate value of residential buildings, are the most influencing agricultural land loss.Land consumption is currently one of the major problems affecting green spaces, natural or agricultural.
