Valuation of ecosystem services on example of river alluvial land
Seják, J. ; Pokorný, J.
In the first decade of 21st century the concept of ecosystem services became one of the most frequently used, especially in interdisciplinary research activities tied with the Earth and life sciences. However, only slightly this concept penetrated into the real advanced market economies that consume decisive part of world natural resources and ecosystem services. In this paper the causes of current unsatisfactory situation in ecosystem service values implementation are analyzed, main valuation methods are described and specified on example of ecosystem services of river alluvial land. Two ecosystem methods developed in the CR are presented.

Dialogue between ecologists and water managers - analyses
Pithart, David
The dialogue between ecologists and water managers in the Czech Republic is analysed. The benefit of this dialogue reflects the need of harmonizing the usual tasks of water management with potential risks of global climate change and permanent threatening of biodiversity. The obstacles of the dialogue are of different character and are listed as follows: 1.Different area and time scale of responsibilities. 2. Difficult harmonization of technique and nature, 3. Different ethical concepts, dealing with the role and position of human in the nature, 4. Different understanding of water cycle 5. Insufitient quantification of some aspects of water cycle 6. Fear of autonomous decisions, resulting in need of very complex and uneffective law system 7. Psychological barriers in initialization of multidisciplinary dialog and teams. 8. Lobbying and corruption. As one of the possible tools to overcame some of the barriers, the concept of ecosystem services is presented.

Retention of nutrients in floodplains
Vymazal, Jan
Nitrogen and phosphorus transformations in floodplains are manifold and very intensive. However, the intensity of the processes depends very much on climatic and geomorphological conditions and also vegetation may play very important role. Probably the most important process responsible for nitrogen removal in floodplains is denitrification which takes place in anoxic/anaerobic soil and litter layers. Substantial removal of nitrogen may also occur via accumulation in the aboveground plant biomass. This process, however, does not remove nitrogen from the system unless the biomass is harvested. The most important process responsible for phosphorus retention in floodplains is sorption on sediment particles deposited during the flood. Removal via plant harvesting may also add to phosphorus removal.

Ecosystem services of a floodplain
Pithart, David ; Křováková, Kateřina ; Dušek, Jiří ; Žaloudík, Jiří
Natural segments of river floodplains have preserved the ability to provide a scale of ecosystem services. The aim of this study is to evaluate in a monetary way the selected ecosystem services of a natural segment of river Lužnice floodplain, Czech republic, based on the analysis and quantification of ecosystem processes and structures. Evaluated services are flood protection, carbon sequestration, biodiversity refugium and production of hay, wood and fish.

Ekosystems services of river floodplain
Pithart, David ; Benedová, Zdeňka ; Křováková, Kateřina
The book of abstractcs contains contributions from the conference „Ecosystem services of river floodplains“, held in Třeboň, Czech republic, in april 2008. The articles deals with functions of river floodplains in the landscape, ecosystem services concept, water, nutrient and carbon retention, biodiversity, floodplain morphology and its development, hydrological aspects of river flooplains, andd water management policies and revitalizations.
