TRANSCRIPT

  • How to value ecosystem goods and services in agriculture at increasing land use pressure ?

    Katarina Hedlund Lund university, Sweden

  • Land use projectionsProduction of goods is increasingFood, biofuels, timber, water useNatural habitats are decliningMitigating climate changeIncreased pressure on land for production of biomass

  • Agricultural land use EU biofuel strategy 1% (produced in EU)6%10% of total area202010%43% of total areaNowicki 2006

  • Current land use in Europe

  • Biofuel production AgricultureNatural grasslandsLand use demands

  • How do we conserve ecosystem services and biodiversity ?Agri-environmental schemes:Extensification

    Protected areasHeterogeneity in landscapes

  • EU common agricultural policy CAPImplemented nationally as rural development plans with additional national fundingCAP (12 000 million /yr), 47% of EU budgetFarming is 5% of European economyCAP subsidiesArea based income supportRural development actionsAgri-environmental schemes

  • Ecosystem services threatened byintensive agriculture

    Natural enemiesPollinationResistance to pests & invasive speciesNutrient cyclingWater retentionCarbon retention

  • Intensification and above ground servicesIncreased heterogeneity may give higher diversityEffect is scale dependentNot true for all species Tscharnkte et al. 2007

  • Soil ecosystem services

    Nutrient cyclingN, P retention and availability to plants Water retentionAggregate structure, organic matter Carbon retentionFuels microbial activity, mitigates climate change

  • Soil ecosystem services-the workers

  • Soil servicesReduced under intensive management

  • SOILSERVICE Conflicting demands of land use: Soil biodiversity and the sustainable delivery of ecosystem goods and services in Europe http://www.kem.ekol.lu.se/soilservice/index.html value soil ecosystem services. predict sustainability of ecosystem services, by field and modelling studies. Build scenarios to identify economical and social drivers of land use

  • Economic valuationa dynamic approach

    Ecosystem services in agriculture- Dynamic network of interacting organisms Responding to changes in land use Depending on spatial and temporal scales
