Management of the Neman River
basin with account of adaptation
to climate change
The main results
The programme of pilot projects on
adaptation
to
climate
change
in
transboundary basins under the UNECE
Convention on the Protection and Use of
Transboundary
Watercourses
and
International Lakes (Water Convention) has
started in 2010
The pilot projects mainly focus on developing
adaptation strategies which lay the ground for
further action.
Main aim of the project is to improve integrated river basin
management and transboundary cooperation in times of a
changing climate in the Neman river basin. The project aims to
strengthen the capacity to adapt to climate change of the
countries sharing the Neman river through supporting dialogue
and cooperation on the needed steps to design an adaptation
strategy in the transboundary context. It will aim to reach a
common understanding on future water availability and water
use taking into account possible climate change impacts.
“One of the priority areas in the field of environment during the
Lithuanian Presidency will be climate change issues. They are
relevant to the whole of Europe, including our country as well”,
Minister of Environment of Lithuania Valentinas Mazuronis

The main features of changes
 Statistically significant increase in annual, winter and
summer temperature (largest changes were observed in
January);
 Statistically significant increase in winter precipitation;
 Maximum spring flood discharge decreased and the
minimum winter flow increased statistically significant in
large part of territory;
 Peak of spring flood and the dates of minimum winter
flow tends occur earlier in the whole basin area.
Near-term future (2021-2050) projections
Climate projections for the whole Nemunas basin was made
with using CCLM model outputs
The regional CCLM model runs are driven by
the initial and boundary conditions of the Global
Circulation Model ECHAM5/MPI-OM. Realizations
of the ECHAM5/MPI-OM model were dynamically
downscaled to a smaller grid using the CCLM
model.
Two greenhouse gas emission scenarios
were used
A1B (relatively high-emission scenario)
B1 (low-emission scenario)
Near-term forecast 2020-2050 was made
Two different hydrological models were used
for the purpose to foreseen runoff changes:
Lithuanian side used WatBal model;
Belarusian side used hydrology-climatic
calculations model (HCCM) based on the
The regional CCLM model covers a large part of
joint solution of the equations of water and the European territory with a high spatial
heat-energy balances
resolution (20 km  20 km).
Climate projections in the
Neman River basin
The main features of foreseen changes
 Mean annual air temperature in the basin territory will increase by 1,7 °C
according to A1B scenario and 1,4 according to B1 climate scenario. For all months
of the year the air temperature rise is projected. The largest changes under both
climate scenarios will likely occur during the cold season of year.
 The annual precipitation amount will increase by 73 mm according to A1B
scenario and by 28 mm according to B1 scenario. The largest positive changes are
foreseen for winter and spring according to A1B scenario, while the most rapid
rise are predicted for autumn according to B1 (negative changes are possible in
some months).
 CCLM model outputs data foresee decrease in sunshine duration in the first half of
the 21st century (relatively the largest sunshine duration decrease will be
observed during the winter months).
 Due to cold season air temperature rise and changes in precipitation composition
snow cover parameters should decline in the future.

Projections of runoff
changes in the Niemen
River basin
Modeling results show that forecasted runoff changes in the near term future are
very similar with observed during the last 50 years.
According modeling results:
 Mean annual runoff will increase insignificantly (decrease in Belarusian part and
increase in Lithuanian part of the basin is very likely).
 The projected maximum spring flood runoff will decrease in the majority of
Nemunas basin. The decrease of maximum monthly runoff is likely to be related
to warmer winters with more frequent thaws. The earlier start of spring flood is
also very likely. As the consequence inundation risk will generally decrease in the
major part of the basin.
 Minimum winter flow will increase. It can be related to the earlier start of spring,
increased winter precipitation and increased frequency of thaws.
 Predicted summer changes are insignificant in the large part of the basin.
Increase in northern part and slight decrease in the southern part of the basin is
modeled.
 Drought probability can increase in the second part of warm period of year.

Forecasted water use for the industry of Belarus will
grow by 0.5-2.0% per year in case of optimistic
scenario of economic development which will also
have slight impact on runoff regime. However, it
was determined that the impact of climate change
will be more important on runoff in the Neman
River Basin on the territory of Belarus in comparison
with forecasted impact of water use changes.
Pilot implementation of common Lithuanian and Belarusian approach for assessment
of water quality of surface waters in the entire Niemen River Basin taking into account
Lithuanian experience for selected list of water quality monitoring stations (WQMS)
and for selected list of water quality parameters including preparation a series of
basin-wide maps regarding classification of surface waters quality.

Average decrease of dissolved oxygen content in surface water in summer forecasted as
0.25 mg/l in Belarus due to climate change. It is comparable with forecast for Lithuania
(Paul Buijs)
Increase of mineralization estimated on 3-10%
Correlation with water temperature and other WQPs were not found take into account
climate change because other factors more significant
Possible increase of nutrient and hydrobiological characteristics deterioration because of
dissolved oxygen content decrease
Development of the preliminary recommendation for improvement of water
management in connection with climate change adaptation (draft proposals on
adaptation measures for particular sectors of economy) for Belarus
Water users most affected to climate
change due to their depends from
water supply from surface waters:
Industry (19);
hydroelectric power plants (11);
Recreation (17);
agriculture including fish industry
(16)
Signing of the Agreement between Belarus, Lithuania,
Russian Federation and European Union and
development of the Neman Water Resources
Management Plan for the entire river basin will be help
to solve most important challenges in adapting to
climate change in the transboundary context.
