As a result of various regulatory reforms, the Common Agricultural Policy (CAP) has gradually achieved value and environmental awareness. However, the most recent studies carried out in the fields of environmental assessment and spatial planning seem to indicate that agricultural policies have not been very effective in achieving landscape aims. Understanding how the CAP affects the landscape can help us to improve its effectiveness and foster a more efficient territorial and targeted approach. This paper aims to show a replicable method for evaluating rural landscape changes and understanding the possible role of CAP as one of the main driving forces. The analysis was conducted in the Piedmont Region (Italy) at the supra-local and local scales by observing land use changes and landscape changes. The main results show that the CAP seems quite effective in maintaining the territorial presence on rural landscapes and in preventing the spread of forests. However, it seems less effective in limiting urban and peri-urban sprawl. The research also shows that in areas with high CAP support, factors that produce negative effects on landscape have increased. In conclusion, the author shows a possible way for the CAP to achieve the landscape purposes.
