Organised by: Thomas Kastner Alexandra Marques 00:00 Thomas Kastner: Assessing and evaluating the impact of the consumption of land-based products on biodiversity: current state-of the art and future directions 12:59 Jonathan Green: Linking supply chain actors and the global trade of agricultural commodities to impacts on species 28:36 Abhishek Chaudhary: Phylogenetic diversity loss associated with global food production consumption and trade 43:35 Rüdiger Schaldach for Jan Goepel: Quantifying and evaluating Germanys biomass consumption on the way to a bioeconomy 2050: a scenario approach 54:17 Philipp R Semenchuk: Multi-scale analysis of the global biodiversity footprints of large cities 1:09:09 Alexandra Marques: A consumption-based indicator for water purification In land systems biodiversity is key to the maintenance of ecosystem functions which in turn underpin the supply ecosystem services harnessed by human societies. While agricultural and forestry activities are essential for human survival and well-being they are also one of the major drivers of global biodiversity loss and ecosystem degradation. Ultimately the consumption of land-based products is the main force behind the demand for land and the intensity of land use. Increasing globalization and industrialization is telecoupling consumption in one place to production in remote regions. To devise land-use strategies that address both production and conservation targets proper accounting tools that link consumption activities to their biodiversity impacts are essential. Main challenges in establishing such accounting tools include: quantifying different dimensions of biodiversity and its temporal trends at large scales the attribution of these trends to individual land-based products and land-use processes and the disentangling of complex international supply chains. These peculiarities are the main culprits why the development of consumption-based tools for biodiversity and ecosystem services lags behind recent advances in accounting of other environmental pressures and impacts. In this session we bring to together researchers at the forefront of consumption-based accounting of biodiversity and ecosystem services. Recent developments will be discussed highlighting the potential robustness and limitations of different approaches. The potential of consumption-based accounting to contributing to an alignment of production and conservation targets in land systems and to minimize trade-offs between the two will be critically explored. The 4th Open Science Meeting of the Global Land Programme was held from April 24-26 in Bern Switzerland. More info at Follow us on Twitter: ,
