Climate change and food production: Challenges and opportunities for research Luis Garrote and Ana Iglesias Technical University of Madrid ENV-NCP-TOGETHER Brokerage Event Malta 31 August 2012
2 climate and CO2 changes water availability land productivity technology development population trade, prices uncertaintydiscount rate A view of the problem from the academic side
Research questions about the future Knowledge needed Support to policy Models, Impacts, forecasting 3 How can food production deal with an uncertain future? Global projections of crop productivity and water availability (World, EU) Adaptation and policy How do we prioritise adaptation to overcome the resulting risks? Assessment and strategy planning process
Research questions about the future Knowledge needed Models, Impacts, forecasting 4 How can food production deal with an uncertain future? Adaptation and policy How do we prioritise adaptation to overcome the resulting risks? 4 Support to policy 4 Many projects provide policy support WASSERMed HIGHNOON enviroGRIDS
2 assertions Scenario analysis Adaptive capacity 5 Understanding uncertainty is useful for facing agricultural challenges Understanding and reducing vulnerability does not demand accurate predictions of the impacts of climate change 1 key issue can climate change science map the future agriculture?
Output: Agro- climatic regions that include climate, farm types, irrigated areas, adaptive capacity Output: Database of simulated crop responses to climate, environment, and adaptive management 12 ClimateCrop model 3 5 4 Output: Land productivity and water demand estimated functions Crop models (DSSAT) Agricultural production functions Climate change analysis Agro- climatic regions Climate change policy analysis Output: Land productivity and water demand estimates responding to climate and farm adaptive management Output: Land productivity and water demand estimates responding to climate and policy (environmental and energy) 6
