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.
