  1. Consequences for land use and water Plant/KeGr Jan Verhagen & Peter Troch

  2. Climate Change Impacts GHG emissions Vulnerability Mitigation Adaptation

  3. Context • No regret measures • Precautionary principle • CAP, WTO • International treaties (FCCC, CBD, CCD, RAMSAR) • Nota’s VROM/LNV/DGIS/V&W • Participation in NoE/IP of EC FP 6 • Sustainable development and global change • Global change and ecosystems • Water cycle/Monitoring

  4. Climate policies • Mitigation: emission reduction and C sequestration • Vulnerability and adaptation: sustainable development • Variability & extremes: risk management & flip over effects

  5. Research questions • What are the combined effects of global change on functions and services of land and water? • What can land and water management contribute to mitigate climate change? • What is the interaction with current land and water use and what are the social and economic consequences? • What are barriers and opportunities to increase the adaptive capacity of land use and water systems?

  6. Impacts • Direct: energy balance, temperature, CO2, rainfall • Indirect: pest & diseases, floods, salt intrusion • Vulnerability • Areas: coastal zone, river valleys, (semi)-arid, peatlands. • Groups: poor (low adaptive capacity), countries with economies rooted in climate sensitive sectors (agr./forestry)

  7. The role of Land use • Mitigation • carbon sequestration: forest, nature, agriculture • emission reduction: agriculture/animal husbandry • Adaptation • changes in farm and forest management • changes in landscape patterns/land use change

  8. The role of water • Mitigation • ground water management in peat lands • Adaptation • Water resource conservation • “ruimte voor water” • Risk management

  9. Wageningen/CCB • The Carbon Challenge • conservation of existing C pools • sequestration by increasing the size of C pools (forest, agriculture, land use change) • Adaptation (sustainable development) • Crop level (selection, stress tolerance) • Farm/forest level (management) • Regional level (choices of functions, integration)

  10. Wageningen/CCB • Water resources (co-operation with IVM and CKO) • Acceleration of hydrological cycle • Floods and droughts • Monitoring, modeling and data assimilation • Ecosystems • Integrated approach

  11. Wageningen/CCB • Hotspots in the developing world • Densely populated (coastal) areas • Marginal areas • Sharper tools (integration and scale linkages) • Integrated natural resource management • Integrated water management • Multifunctional land use
