General circulation models: model label, country of development, period for which the data were used, the approximate horizontal resolution of data
• As the simulations of future climate with GCMs are based on a number of emission scenarios, usually SRES A2 and B2, the local climate change projection were additionally scaled to other marker SRES emission scenarios (A1T, A1b, A1Fl, B1)

-based on direct GCM output interpolated to geographic location 21.5°E and 41.5°N with regard to the period 1990.
Mean: average across different emission scenarios and different GCMs, Low/High: minimum/maximum across different scenarios averaged across different GCMs.

Deficiencies of direct GCM outputs
• only a rough description of expected climate change (mostly the changes of average conditions on the level of entire country).
• spatial and temporal variability of meteorological parameters and heterogeneous climate/ topography not considered
• can present a benchmark for more detailed methods for regional projection of future climate change

Projected global averaged surface warming at the end of the 21st century and examples of some projected regional impacts (Europe)
(IPCC AR4)
…. In Southern Europe, climate change is projected to worsen conditions (high temperatures and drought) in a region already vulnerable to climate variability, and to reduce water availability, hydropower potential, summer tourism and, in general, crop productivity….
…. high confidence that many semi-arid areas (e.g. Mediterranean basin) will suffer a decrease in water resources due to climate change…
Drought Management Centre for Southeastern Europe –
DMCSEE
• South East Europe Program • Aim of the project: improve drought preparedness and help
to reduce drought impacts• Co-funded by the European Union and the partner
countries• 2009-2011, 2.2 M EUR• 15 institutes from 9 countries (Slovenia, Hungary, Bulgaria,
Greece, Croatia,Serbia, Montenegro, FYROM, Albania)• Lead partner: Environmental Agency of Slovenia• Hydrometeorological Service of Republic of Macedonia
joined the project in December 2010 • Web: www.dmcsee.org

Conclusions
• Different climatic regions of Macedonia will respond slightly different on large scale climate changes
• Need for further investigations for critical review of present results with awareness of all the associated uncertainties
• Drought management policies and tools are necessary for adaptation measures
• International cooperation and sharing knowledge
