This article describes a systemic approach to the functioning of a hedgerow landscape with environmental implications. After analysing land-use/land-cover and landscape trends, identifying and ranking the driving forces of change, the systemic analysis highlights the scales of change and the stakeholders involved in the evolution of these landscapes. This approach shows the complexity of land-use change processes in intensive agricultural areas with a highly fragmented landscape. It is an essential preliminary step in simulating future changes in agricultural practices and evaluating their environmental impacts. This is key to the implementation of sustainable policies.
