Holistic and multi-transdisciplinary approaches, where multiple goals are achieved in order to improve resilience in societies and ecosystems in the short, medium, and long term, are ideal, even utopian. Hence, science has come together with practical experiences that highlight the importance of working at a ‘landscape’ level. Landscapes, as socio-ecological systems, are key for sustainability and sustainable development, and they represent a realistic unit to interconnect local, national, and ultimately global scales. International efforts regarding holistic natural resources management approaches are not new; however, they are currently pointing to an Integrated Landscape Approach (ILA). Based on a documentation review and analysis, the present article review aims to promote the disambiguation of the ILA concept and provide an updated synthesis knowledge on the ILA. Especially for the forest sector, the ILA has been identified as particularly beneficial, strongly highlighted by the scientific literature, and with an infrastructure of organizations that are encouraging it. The paper presents the rationale of the science behind the concept, as well as the main principles, we identified a variety of definitions with some significant points of overlap, we highlight the inclusion of ILAs in the current international arena and the relationship of ILA’s and Jurisdictional Approaches, and we make a review of the ILA in a challenging world of rapid change. Our review recognizes ILAs socio-ecological management strategy to reconcile conservation, development, climate change, and human well-being goals. ILAs naturally have a social and idealistic construction behind it, which might be just as necessary andsignificant as the journey toward sustainability itself.
