Homo sapiens, as the highest biological species, develops and upgrades its ideas about the environment, and changes its behaviour to
the natural factor; this way, it changes the institutional norm, which has the greatest impact on human behaviour. Natural ecosystems
maintain their balance themselves. Regarding artificial systems such as agro-systems, when the anthropogenic impact violates their
adaptive capacity, development becomes unsustainable. The current research is aimed at finding the synergy between EU policy and
the management of land resources. The policies with the most influence are the Green Deal and the CAP, and are the main subject
of this research. Their impact on land management is shown using a scientific method, and includes the review of literature sources,
expert methods, and ad hoc evaluation, plus SWOT analysis. In agriculture, a number of policies have changed in order to create
synergies between the biological factor and the institutional environment. There is potential for synergy between policy and good
management.
