Poverty, food insecurity, climate change and biodiversity loss continue to persist as the primary environmental and social challenges faced by the global community. As such, there is a growing acknowledgement that conventional sectorial approaches to addressing often inter-connected social, environmental, economic and political challenges are proving insufficient. An alternative is to focus on integrated solutions at landscape scales or 'landscape approaches'. The appeal of landscape approaches has resulted in the production of a significant body of literature in recent decades, yet confusion over terminology, application and utility persists. Focusing on the tropics, we systematically reviewed the literature to: (i) disentangle the historical development and theory behind the framework of the landscape approach and how it has progressed into its current iteration, (ii) establish lessons learned from previous land management strategies, (iii) determine the barriers that currently restrict implementation of the landscape approach and (iv) provide recommendations for how the landscape approach can contribute towards the fulfilment of the goals of international policy processes. This review suggests that, despite some barriers to implementation, a landscape approach has considerable potential to meet social and environmental objectives at local scales while aiding national commitments to addressing ongoing global challenges.
There is a growing disconnect between the international conferences where grand solutions for tropical conservation are designed and the complex local realities in tropical landscapes where plans need to be implemented. Every tropical landscape is different and no ''one size will fit all.'' There is a tendency for global processes to prescribe simple generalized solutions that provide good sound bites that can be communicated with political actors and the media. Sustainable outcomes in tropical landscapes require locally adapted, unique approaches supported by long-term processes of learning and adaptation. Tropical biologists and conservationists can play a key role by establishing effective local-global links and by directly engaging in local policy discourses while remaining connected to evolving political imperatives.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
