    Challenges and opportunities in mapping land use intensity globally
    (Amsterdam : Elsevier, 2013) Kuemmerle, Tobias; Erb, Karlheinz; Meyfroidt, Patrick; Müller, Daniel; Verburg, Peter H.; Estel, Stephan; Haberl, Helmut; Hostert, Patrick; Jepsen, Martin R.; Kastner, Thomas; Levers, Christian; Lindner, Marcus; Plutzar, Christoph; Verkerk, Pieter Johannes; van der Zanden, Emma H.; Reenberg, Anette
    Future increases in land-based production will need to focus more on sustainably intensifying existing production systems. Unfortunately, our understanding of the global patterns of land use intensity is weak, partly because land use intensity is a complex, multidimensional term, and partly because we lack appropriate datasets to assess land use intensity across broad geographic extents. Here, we review the state of the art regarding approaches for mapping land use intensity and provide a comprehensive overview of available global-scale datasets on land use intensity. We also outline major challenges and opportunities for mapping land use intensity for cropland, grazing, and forestry systems, and identify key issues for future research.

    A conceptual framework for analysing and measuring land-use intensity
    (Amsterdam : Elsevier, 2013) Erb, Karl-Heinz; Haberl, Helmut; Jepsen, Martin Rudbeck; Kuemmerle, Tobias; Lindner, Marcus; Müller, Daniel; Verburg, Peter H.; Reenberg, Anette
    Large knowledge gaps currently exist that limit our ability to understand and characterise dynamics and patterns of land-use intensity: in particular, a comprehensive conceptual framework and a system of measurement are lacking. This situation hampers the development of a sound understanding of the mechanisms, determinants, and constraints underlying changes in land-use intensity. On the basis of a review of approaches for studying land-use intensity, we propose a conceptual framework to quantify and analyse land-use intensity. This framework integrates three dimensions: (a) input intensity, (b) output intensity, and (c) the associated system-level impacts of land- based production (e.g. changes in carbon storage or biodiversity). The systematic development of indicators across these dimensions would provide opportunities for the systematic analyses of the trade-offs, synergies and opportunity costs of land-use intensification strategies.

    Identifying a Safe and Just Corridor for People and the Planet
    (Hoboken, NJ : Wiley-Blackwell, 2021) Rockström, Johan; Gupta, Joyeeta; Lenton, Timothy M.; Qin, Dahe; Lade, Steven J.; Abrams, Jesse F.; Jacobson, Lisa; Rocha, Juan C.; Zimm, Caroline; Bai, Xuemei; Bala, Govindasamy; Bringezu, Stefan; Broadgate, Wendy; Bunn, Stuart E.; DeClerck, Fabrice; Ebi, Kristie L.; Gong, Peng; Gordon, Chris; Kanie, Norichika; Liverman, Diana M.; Nakicenovic, Nebojsa; Obura, David; Ramanathan, Veerabhadran; Verburg, Peter H.; van Vuuren, Detlef P.; Winkelmann, Ricarda
    Keeping the Earth system in a stable and resilient state, to safeguard Earth's life support systems while ensuring that Earth's benefits, risks, and related responsibilities are equitably shared, constitutes the grand challenge for human development in the Anthropocene. Here, we describe a framework that the recently formed Earth Commission will use to define and quantify target ranges for a “safe and just corridor” that meets these goals. Although “safe” and “just” Earth system targets are interrelated, we see safe as primarily referring to a stable Earth system and just targets as being associated with meeting human needs and reducing exposure to risks. To align safe and just dimensions, we propose to address the equity dimensions of each safe target for Earth system regulating systems and processes. The more stringent of the safe or just target ranges then defines the corridor. Identifying levers of social transformation aimed at meeting the safe and just targets and challenges associated with translating the corridor to actors at multiple scales present scope for future work.
