The main scope of this study is to review and present constrains and practices across the sectors of forest and water resources management, flora and fauna biodiversity. The hypothesis is that common practices in the forest field combined with inefficient and obsolete legislation are responsible for delays in the implementation of a national forest policy, which will promote sustainability. A systematic reviewing methodology was applied so to ensure a rigorous and repeatable method of sustainability constraints identification and evaluation. The identification of the constraints can promote the improvement of legislation, the revision of common practices concerning the forest sector and finally can help the forest managers to better understand how to work effectively within legal, regulatory and operational environments deriving from forest policy.
