By examining the shift towards multifunctional agriculture, the chapter underscores the EU’s commitment to balancing agricultural productivity with environmental sustainability. It explores the legal frameworks and policy instruments that support this integration, emphasizing the importance of maintaining ecological balance and promoting sustainable practices. The chapter concludes by addressing the challenges and opportunities in fully realizing the potential of ecosystem services within the EU’s agricultural landscapes, advocating for continued research, innovation, and collaborative efforts to advance sustainable development.
