Assessment Agency: National institute for strategic policy analysis - PowerPoint PPT Presentation

PBL Netherlands Environmental Assessment Agency: • National institute for strategic policy analysis • Environment, nature, spatial planning • Independent, policy oriented, scientifically sound Stefan van der Esch | PBL 1

Outline • Policy cycle • Stages determine data needs • Use of earth observation data in policy development • Examples: land subsidence and the Global Land Outlook • Portals • Missing links • What would we like to know? Permission via UNCCD Secretariat, Global Land Outlook 1 Stefan van der Esch | PBL 2

Uses in policy • Deforestation and REDD • Air quality • Climate and climate change • Land use and land use change • Crop yield predictions • Early warning and emergency responses Permission via UNCCD Secretariat, Global Land Outlook 1 Stefan van der Esch | PBL 5

Land subsidence Steps: • Satellite data • Processing and combining • Causes, effects, consequences • Scenarios/extrapolation (future problem) – models • Goals, ambitions (political) • Response inventory • Response evaluation • Costs action/inaction • Policy decisions on measures • Implementation • Evaluation and monitoring Stefan van der Esch | PBL 6

Global Land Outlook • PBL: outlook component • Wageningen University, Utrecht University, EC Joint Research Centre Stefan van der Esch | PBL 7

Global Land Outlook • Where (in the world) is land condition changing? • By how much? • Is management or climate driving that change? • What are future impacts? • What options do we have? • How effective are they? Stefan van der Esch | PBL 8

Takeaways : Missing links? • Land management • Use for policy is most often not direct • Soils, land degradation, forest • Demands (speed, resolution, degradation repetition, accuracy) change • Livestock, yields dependent on phase in policy cycle • Water quality, rivers? • Attribution (determining causes of • People, economics, distribution observed change) is where it often (e.g. land tenure) gets difficult. But necessary to • Ocean floor identify effective response options. • Talk to science-policy organizations. Stefan van der Esch | PBL 14
