Work done since the 2nd IDMP CEE workshop till now (April 2014 – October 2014)
1. On the base of WorldClim dataset
http://www.worldclim.org/node/1 more than 100
maps (air temperature, precipitation and De
Martonne index) were created for the 4 GWP CEE
countries:
• Current (1950-2000) climate conditions and De
Martonne index;
• Future (2050 and 2070) climate conditions and
De Martonne index; (RCP2.6, RCP4.5, RCP6,
and RCP8.5).

2. Determination of the vulnerability zones of the current
climate and years of 2050 and 2070
(RCP2.6, RCP4.5, RCP6, and RCP8.5)
Country determination of vulnerability zones is based on the following values of the
index of de Martonne (IDM):

Forest areas on pilot territory by De Martonne classes in present climate and in RCP's (thouth. ha)
All climatic scenarios forecast sufficient aridization of climate on the whole pilot territory by 2050 and 2070 years that is unfavorable for forest vegetation.
All scenarios forecast significant aridization in northern part of the pilot territory and disappearance of moderately humid climate (D-zone), with the most productive forests.

Forest areas by climate classification in present and in RCP 2,6
2070
2050
Present climate (1950-2000)
RCP 2,6 is the “optimistic” scenario of climate change that is characterized by aridization of climate on the pilot territory by 2050, more significant on the north (Sumy region) where climate will change from moderately humid to moderately arid, less on center (Kharkiv region) – change form slightly humid to moderately arid and appearance of semiarid climate on the south (Lugansk region).
By 2070 this scenario provides slight more humid climate comparing to 2050 but not to the present climate values: in Sumy region – slight humid climate is expected, in Kharkiv and Lugansk – moderately arid (only on east of Lugansk region semiarid climate will remained).
![Page 16: Third IDMP CEE workshop: Assessment of drought impact on forest ecosystems by Galia Bardarska](https://reader034.vdocuments.us/reader034/viewer/2022042714/556140d5d8b42a162a8b5692/html5/thumbnails/16.jpg)
Forest areas by climate classification in present and in RCP 4,5
2070
2050
Present climate (1950-2000)
RCP 4,5 is characterized by gradual aridization of the climate on the whole territory by 2070: all territory of Lugansk region and southern and central districts of Kharkiv region will become semiarid, and all remaining part of the pilot territory will become moderately arid.
![Page 17: Third IDMP CEE workshop: Assessment of drought impact on forest ecosystems by Galia Bardarska](https://reader034.vdocuments.us/reader034/viewer/2022042714/556140d5d8b42a162a8b5692/html5/thumbnails/17.jpg)
Forest areas by climate classification in
present and in RCP 6,0
2070
2050
Present climate
(1950-2000)
According to RCP 6,0 sufficient aridization of climate is expected: by 2050
Sumy and northern part of Kharkiv region will become moderately arid, while
on the remaining part of Kharkiv and all Lugansk the climate will be semiarid.
By 2070 the large part of the territory will become moderately arid, only in
eastern and central districts of Lugansk region it will be semiarid climate.

Forest areas by climate classification in present and in RCP 8,5
2070
2050
Present climate (1950-2000)
The worst climatic conditions for forest vegetation are expected according to RCP8.5 scenario: by 2050 the large territory (all Lugansk, all Kharkiv regions and southern districts (Lebedin, Trostynets and Ohtyrka) and northern districts (Seredino-Buda and Shostka) of Sumy region will become semiarid; than climate will become drier and by 2070 the whole pilot territory will have semiarid climate.

Tree species productivity (growing stock) in different climate condition (m3 per ha)
In present climate the most favorable climate conditions for forests in terms of timber productivity
are in moderately humid climate.
Productivity of Oak, Pine and Ash decrease on 40% in moderately arid climate comparing to
moderately humid.
Some of tree species (eg spruce) can only grow in humid climates and when climatic conditions
will change, spruce will disappear.

Final outputs at the moment
Discussions on maps of different scenarios and determination of vulnerability zones in each country. After common approval of the results, the report of Milestone 3 will be presented in October, 2014.
Difficulties
There are some problems with actual forests data.
Production of more than 100 maps and its checking took much more time than planned before.

Changes from the original plan
The future period 2100 was changed with 2070 according to IPCC AR5. PRG approved the change of the year 2100 for the future period into 2070.
Links with other IDMP CEE activities
There is a link with Act. 2.1, but also with other activities which will be confirmed after Budapest meeting.

Plans for the final period (October 2014 – March 2015)
- to the end of 2014: preparing the report of Milestone 3, establishment of programs for forest adaptation measures and mitigation the negative effect of climate change on them in 4 GWP CEE countries, organization of NCDs,
- March 2015: preparing the final report on Act. 5.2 according to PRG comments and dissemination of data (publications, CDs production etc.).

forests between 4 GWP CEE and establishment of
recommendations for forest adaptation measures and
mitigation actions.

Problems expected
Limited computer resources to process high resolution gridded climate and forestry data.
Change from the original plan
Regarding the actual local problems, new documents on climate changes impact and PRG comments the final content of Act.5.2 case will be up-dated.
Implementation of the results and follow-up activities
Some results of the Act. 5.2 would be involved in second RBMPs. There are different ideas for follow-up projects regarding the relation between water and forests.
