Landscape approaches have become en vogue in the past couple of decades. Originating from nineteenth-century landscape geography, this renewed popularity since the 1980s is fueled by debates on-among others-nature conservation, landscape restoration, ecosystem services, competing claims on land and resources, sectorial land-use policies, sustainable development, and sense of place. This review illuminates the ambition and potential of these landscape approaches for interdisciplinary and cross-sectoral collaboration. To show this, we work with a T-shaped interdisciplinary model. After a short history of the landscape approaches, we dive into their key dimensions-from ecology to economics and culture to politics. Thereafter, we bring these dimensions together again and reflect on the integrative potential of landscape approaches for offering common ground to various disciplines and sectors. Two examples of applications are also dealt with: a landscape governance framework and a landscape capability framework.
