Adaptation to climate variability and change in agriculture

Transcription

1 Adaptation to climate variability and change in agriculture Reducing Vulnerability to Climate Variability and Change in Macedonian Agricultural Systems Skopje, 12 May 2010 Ana Iglesias Universidad Politécnica de Madrid, Spain 1

2 Agriculture cannot solve the problem, but can be part of the solution EC white paper (2009): agriculture is the sector most impact in the EU, but the one that has largest potential for adaptation

3 Reasons for concern Managing the unavoidable (adaptation) Lessons from the EU initiatives Measures that make sense today and in the future: building adaptive capacity Some challenges: uncertainty, synergies between adaptation and mitigation 3

4 Reasons for concern Possible effect Confidence level Optimal location of crops (zones) change high Crop productivity change high Irrigation requirements increase high Soil salinity and erosion increase medium Damage by extremes increase medium Environmental degradation increase medium Pests and diseases increase medium 4

5 Managing the unavoidable Lessons from EU initiatives EU White paper on adaptation National Adaptation Strategies EU funded research 5

6 Adaptation questions What components of the farming system are particularly vulnerable, and may thus require special attention? Can optimal management decrease vulnerability to climate? What are the characteristics of optimized crop varieties? Will climate change significantly affect agricultural water demand fro agriculture? Can the water/irrigation systems meet the stress of changes in water supply/demand? 6

9 Crop production (Iglesias et al., 2007) Crop yield changes under the HadCM3/HIRHAM A2 and B2 scenarios for the 2080s and for the ECHAM4/ RCA3 A2 and B2 scenarios for the 2080s and ECHAM4/ RCA3 A2 scenario for the 2020s compared to baseline (Iglesias et al. 2007) 9

10 Decline of high quality crops Regulations may limit opportunities 10

11 Heat stress and drought in summer Floods, water-logging Environmental degradation New crops, energy crops 11

19 Role of RD (CAP) A flexible framework Axis 1 Farm modernization Restoring & prevention Farm advisory services Training Axis 2 Agri-env measures Payments linked to WFD Axis 3 Diversification into nonagricultural activities Leader 19

20 Rural development policy is a EU policy that will permit in the future: to face these differential impacts of climate change that will exacerbate territorial disparities To contribute to solidarity Provides a flexible framework to contribute to develop actions at the local level 20
