area / workshops / TW52 / presentations.

Austria

LP, Gerhard Kuschnig, (Vienna Waterworks, MA 31)

� Rax, Schneeberg, Wildalpen, Hochschwab are shown and its protection areas, pastures

(active, abandoned),

� Problem: determine the risk as a function of hazard and vulnerability

o Risk: microbial contamination of spring

o Hazard: cattle

o Vulnerability: Determined by natural background (soil, geology, vegetations,…)

� Question: under climate change circumstances: does risk change?

o Vulnerability changes: increased precipitation – increased infiltration, increased

erosion

o Change in vegetation – effects have to be estimated

o Does hazard change due to CC? Hazard: emissions, driving forces, human activities,

physical, chemical, biological and microbiological, impacts on ecosystems, counter

measures

� Which information is needed for evaluation?

o For steady state

o For CC-scenarios

Roland Köck from the University of Applied Life Sciences (Vienna)

Land use category forestry



page 4 of 16

� The use of land use maps

o The VWPZ is situated in a karstic environment

o Stability of soil formation is of crucial importance (e.g. Information of humus depth is

an important information)

� Possibilities to simulate soil information

o A simulation model (PICUS v1.4)

o Ökogramm: Ellenberg

Remarks

Miso Andielov: Which data are we supposed to gather? Answer: You should find out, which are the

tree species on your sites. You can also enhance the data by personal findings.

Slovenia

PP4 – presentation by Barbara Cencur Curk, University of Ljubljana and Branka Bracic Zeleznik (Public

Ulility JP Vodvod - Kanalizacija

� Test area Mura valley it is dense agricultural area

� Pollutions in the water fields

o Desetil atrazine: are decreasing due to an analysis and measures

o Nitrates in the water are shown

Remarks

Gerhard Kuschnig: How will it change due to climate change? Answer: Farmers try not to use

pesticides anymore.

Hungary

PP6 – Judith Zachar

� Test areas: Bükk (karst) Nyírség (porous)

� Evaluate land use changes since the 1950s

� There are 5 categories: changes mainly in forest and settlements (increase)

o Wetland, lake, river

o Forest

o Open areas

o Grape, orchard

o Settlements

� Water quality: Nitrate content is increasing a lot after 1995. Shallow groundwater is nitrate

contaminated. Deep groundwater is not nitrate contaminated.

Romania

PP08 presented by Ana Popovici, Romanian Academy (Bucharest)

� Evaluation of existing land uses

o Land use maps for test areas – Corine Land Cover 1990. 2000 and 2006 (EEA)



page 5 of 16

o Identification and analysis of the main land use changes over the post-socialist period

� Land use categories

o Agricultural land

o Built-up areas

o Industrial and commercial units

o Inland marches, water covered areas

o Forest

� Clue-S model (the Conversion of Land Use and its Effects at Small regional extend)

� GEPIC provides a practical tool for simulating crop yield and crop water productivity (CWP) by

integrating the EPIC model (Environmental Policy Integrated Climate) with GIS

Petru Enciu presents Land use and water quality data.

� Water has been analyzed of water quality trends

o Oltenia Plain: chloride, nitrates, nitrite, ammonium will increase in test areas.

� Future water supply: deep water

o Banat Plain: arsenium (increased skin cancer) and manganese is too high up to 38 times (Bega –timis interstream quality)

� Future water supply still unknown

o Ivanda Village: because of salts used as medical water (groundwater)

Bulgaria

PP11 Ivan Marinov presents the test area Struma river basin.

� Forest land distribution

o Forest vegetation types (for watersheds) and forest cover and age of forest (30 years

of measurement)

� Water quality

o Quality of surface water with 16 hydrometric stations

o Nitrogen concentrations increase slightly

o Complex index SS – a slight decrease

� Analysis of trends in water quality: important to focus on a smaller scale

Serbia

IPA 1: Sasa Milanovic

� Beljanica and Stara Planina land use is shown on diagrams and images (CORINE maps) in the

future soil maps are going to be developed

� Groundwater Quality is high

IPA 2 partner Zeljka Rudic , Jaroslav Verni Insitute, Serbia, Belgrade; presents the Land use



page 6 of 16

� Water quality is presented (chloride is high)

Croatia

10% P: presentation by Ozren Hasan - Croatian Geological Survey (Zagreb)

� Presentation of test areas: Vrankso lake, Cres Island, Bokanjacko blato: data is available up to

the 1950s, but there is no data before WW2.

� Water quality: increase of chlorides in seasonal as well as total values in Cres due to tourists (danger of seawater intrusion)

� Blasko polje: nitrites decreases due to sanitary zones

Italy

Fulvio Celico, University of Molise

� Land use maps were gathered

� Maps of soil thickness

� Contamination changes in autumn and spring

o After freezing of the soil, a significant decrease in viable cells within the soil is

observed

o Expected impact of microbial contamination of spring water seems to be “temperature depended”, thus: an increase in contamination in winter season is

expected where freezing won´t occur, due to decrease of cell death

o An increase in contamination in autumn could be observed in case of significant

increase of summer temperature, due to increase in cell growth

Excursion: Watermill Mura

� Application of DSPIR in different landuse scenarios using expected future landuse and

estimated future water quality data

Roundtable discussions

� Q1: Identification of Drivers, Pressures, States, Impacts for each landuse type and related

indicators.



page 7 of 16

� Q2: Identification of landuse needs to be taken into account to understand if they are

compatible with future climate scenarios.

� Q3: Identification of methods necessary to analyze factors and mechanisms which influence

the transport of selected contaminants.
