1 Anomalies of global air temperature during the last Millennium, relative to the period 1902-1980

2 Anthropogenetic related risks 1998 Global temperature 1998 – the warmest

3 ECHAM4 Global Climate Model

4 GCM simulated changes in monthly precipitation in Bulgaria for the 2050s, relative to 1961-1990 Climate Change Scenarios for Bulgaria

5 ECHAM4 climate change scenario for air temperature in May at the 2020s (2.8 o x 2.8 o ) GCM LIMITATIONS

6 (MAGICC/SCENGEN) ECHAM4 GCM scenario of annual air temperature in Europe during the 2050s (A2 SRES emission scenario), (A2 SRES emission scenario), relative to 1961-1990

7 Change in summer mean temperature (oC) for the HadCM3 and PCM climate models coupled with the A2 SRES scenario for 2080

8 Change in summer precipitation (mm/month) for the HadCM3 and PCM climate models coupled with the A2 SRES scenario for 2080

9 Departures of the CERES simulated yield of maize at the Bulgarian region, relative to 1991-2000

10 WINTER WHEAT 2011-2020 HadCM3 – A2 vs. 1981-1990 Bulgaria Poland

11 WINTER WHEAT 2071-2080 HadCM3 – A2 vs. 1981-1990 Bulgaria Poland

12 MAIZE 2011-2020 HadCM3 – A2 vs. 1981-1990 Bulgaria Poland

13 MAIZE 2071-2080 HadCM3 – A2 vs. 1981-1990 Poland

14 HadCM3 SOYBEANS 2011-2020 HadCM3 – A2 vs. 1981-1990 Bulgaria Poland

15 SOYBEANS 2071-2080 HadCM3 – A2 vs. 1981-1990 Poland

16 ADAPTATION OPTINS  Zoning crop production in agricultural land areas with elevation below 1000 m agricultural land areas with elevation below 1000 m  Change in crops  Change in sowing dates  Change in irrigation  Change in crop hybrids andcultivars

17 ADAPTATION OPTINS  Change in fertilization  Change in management practices  Change in management of diseases andpests control  Governmental policy and strategies in the field of agriculture
