New map of global land system archetypes

Land use is a major driver of global environmental change and many of the grand sustainbility challenges humanity faces in the 21st century. Unfortunately, our understanding of the global patterns of land use is limited, mainly because global data on land management intensity are scarce. A recently published in the journal Global Environmental Change combined a range of land use, environmental, and socio-economic datasets to provide a global map of land systems. This freely available map will be useful for assessing the environmental and social outcomes of changing land use. This study emerged from a collaboration between Humboldt-University Berlin and the Environmental Resaerch Centre (UFZ) in Leipzig and was jointly supported by the German BMBF and the Einstein Foundation Berlin.

Research frontiers for better understanding trade-offs between agricultural production and biodiversity conservation

How to balance agricultural production and biodiversity conservation has emerged as a central question in Land Use Science and Conservation Biology. A new paper by Ricardo Grau and co-authors, recently published in Current Opinion in Environmental Sustainability, identifies research frontiers in the analysis of trade-offs between agriculture and conservation. The paper highlights that assessments of alternative land use strategies, such as land sparing and land sharing, could benefit from an improved consideration of environmental heterogeneity (in biodiversity patters and agricultural productivity), teleconnections, and the socio-economic constrants of particular land use strategies.

Improving understanding of changes in land use intensity

Two new papers recently published in the journal Current Opinion in Environmental Sustainability address existing knowledge gaps surrounding land use intensity. In the first study, Erb and co-authors review the disciplinary context of research on land use intensity, discuss conceptualizations of indicators to measure land use intensity, and propose a new, systemic framework for addressing land use intensity. The second study by Kuemmerle and co-authors review approaches to map land use intensity globally, summarize existing quantitative, spatially-explicit metrics, and outline challenges and concrete steps forward to better characterize land use intensity and changes therein at the global scale. Both papers emerge from a Global Land Project (GLP) synthesis effort and research carried out within the EU FP7 Integrated Research Project VOLANTE.

New study highlights barriers to interdisciplinary research

Environmental problems are complex and require expertise from multiple disciplines, but environmental research that integrates natural and social science can be challenging. A new study in BioScience carried out by the 2009 class of fellows of the Coupled Human and Natural Systems Network (CHANS-Net) highlights both the benefits of and barriers to successful interdisciplinary resaerch. A comprehensive survey among environmental scientists showed that respondents identified many advantages and rewards of interdisciplinary research, but also revealed substantial barriers at the institutional level. The survey furthermore suggests that interdisciplinary training should begin as early as possible in scientists' careers.

Future land use effects on habitat connectivity

Maintaining habitat connectivity is a major challenge for conservation planners. Using an example from Southern Spain, a new paper by Maria Piquer-Rodriguez highlights how conservation planning for connectivity can be improved by considering future scenarios and and by identifying those landscape connectors that are at highest risk of being lost.

Biogeography class trip to the Museum für Naturkunde

After the final exam of the semester the Biogeography class had the opportunity to learn about research and conservation in action with a back-stage tour of the Museum für Naturkunde. Students had the chance to see the some of the 30 million objects in the Museum’s collection along with learning about behind the scenes cataloging and research techniques including amphibian studies in Western Africa and microscopic digitalization of specimens.
