Sava White Book – The River Sava: Threats and Restoration Potential

Weißbuch Save_Cover (c) EuroNaturThe Sava is one of the most interesting and complex rivers in Europe. Along its course of 926 kilometres, the Sava features the entire spectrum of different rivers habitats. Together with tributaries, the Sava basin constitutes one of the best preserved and most diverse river systems in Europe. Unfortunately, like so many other European rivers, the Sava stands at a crossroad: on the one hand improving the ecological condition of water bodies is a clearly defined goal of the European Union. On the other hand, flood protection, recreational use and transport capacities, etc. are to be increased as well. Moreover, hydropower developments, sediment exploitation and navigation upgrades put further strain on the river.

In which direction is the Sava going? This is the very question we asked ourselves within the context of the “Save the Blue Heart of Europe” campaign. Our answer is this White Book. It shall serve as an extensive and comprehensive overview of the situation of the Sava. However, what makes this White Book truly unique is that it is the first study offering suggestions for area-specific ecological flood control and river restoration projects. In other words, we show where former alluvial areas could be naturally flooded once again and in which sections the Sava’s river bed should be given more space.

Financing for hydropower in protected areas in Southeast Europe

coverbildSoutheast Europe is experiencing a wave of hydropower projects. In a region with a deadly combination of Europe’s last wild rivers, rampant corruption and inadequate nature protection, the potential for damage is immense. A recent study by Dr Ulrich Schwarz (see study “Hydropower Projects in Protected Areas on the Balkans” below) found that almost half of the planned projects are in protected areas. This research aims – to the extent possible given the secrecy around the financial sector – who are the main actors involved in financing hydropower projects in the region, both overall and inside of protected areas. The extensive analysis shows that multilateral development banks are playing a key role. The European Bank for Reconstruction and Development (EBRD), the European Investment Bank (EIB), and the World Bank’s International Finance Corporation (IFC) have extended loans totalling EUR 818 million to no less than 75 hydropower projects, including 30 directly affecting protected areas like national parks, Natura 2000 sites, and Ramsar sites.

Hydropower Projects on the Balkan Rivers – Update

TitlebildIn a follow-up study of the initial “Hydromorphological Status and Dam Projects” study from 2012 (U. Schwarz), we included small hydropower plants as well, when previously only those over 1 MW were recorded. A total of 2,683 future hydropower projects have been recorded on the Balkan Peninsula.  Additionally, 714 existing dams were found in this region. Based on four size categories the 2,683 planned HPPs are distributed as follows: 68 very large projects (> 50 MW), 178 large projects (10-50 MW), 867 medium projects (1-<10 MW) and 1,570 small projects (0.1-< 1 MW) were identified.

Hydropower Projects in Protected Areas on the Balkans

TitelbildThis study aims to quantify the number of hydropower projects that are planned within protected areas on the Balkan Peninsula. A total of 1,640 projected hydropower plants (HPPs) have been examined based on a detailed and categorised network of protected areas. A total of 535 planned projects or 32% of the projects are planned in strictly protected areas. In addition, 282 HPPs (17 %) are projected inside other protected areas with a weaker protection status. Altogether, 817 or 49% of all projected HPPs fall in protected areas, which points to the fact that this practice is the rule rather than an exception. This indicates a very high pressure of hydropower on protected sites.

The Huchen Hucho hucho in the Balkan region

TitelblattDistribution and future impacts by hydropower development

The Huchen or Danube Salmon is one of the most enigmatic species of Europe’s freshwater fauna. It is a sensitive indicator species for some of the most ecologically valuable rivers in the Danube drainage. Historically, the species was wide-spread across the entire Danube basin. Since the late 19th century, however, Huchen populations declined by two thirds and the remaining populations are now highly endangered by hydropower development. But knowledge on the distribution of the Huchen on the Balkan Peninsula has been incomplete.

Within the context of the international campaign “Save the Blue Heart of Europe”, 18 scientists from 7 countries explored for the first time, in which rivers between Slovenia and Montenegro the Huchen can still be found. The results clearly show that the Balkan rivers constitute the last big hot spot for this species. Self-sustaining populations of Huchen were found in 43 rivers with a total length of 1,842 kilometres. This corresponds to 65 percent of all known Huchen stretches worldwide. However, 93 hydropower plants are projected directly in stretches with healthy Huchen populations. Experts predict a population decline of up to 70%, if these dams become reality.

Compliance of HPP Plans in Mavrovo National Park in Macedonia with EU legislation

TitelplatzThe compliance with EU legislation and guidelines of all hydropower projects inside the Mavrovo National Park in Macedonia  was analyzed by the Ökobüro – an environmental alliance based in Austria. Legal experts conclude that the projects strongly violate EU law. Particularly alarming is the lack of environmental data leading to false and misleading environmental assessments. Another important aspect is that the cumulative effects of several projects planned in the area (a total of 22 hydropower facilities!) would have had to be considered before even starting project permitting procedures. This was not the case. Find the study here: Nature destruction under the guise of energy security? Analysing EU law compliance of HPP Plans in Mavrovo NP in Macedonia

Hydromorphological Status and Dam Projects

Titelphoto River AssessmentIn preparation for the campaign, we examined the hydromorphology of 35,000 river-kilometres and came to a pleasing conclusion: 80% is still in good condition – that is the highest percentage in all of Europe. In addition, we did research on the proposed and planned dam projects in the Balkan region. Find the study about hydromorphology and the dam projects here:

Balkan fish and molluscs

Titelbild FishThe Balkan region is Noah’s Ark for Europe. Europe’s fly fishers have known it all along, but now there is scientific proof: the Balkan region is the most important hotspot for threatened fish species. This is also true for freshwater bivalves and freshwater snails.

In his study, renowned fish expert Dr Jörg Freyhof verified the importance of Balkan rivers for Europe’s fauna. 69 fish species can only be found in the Balkan region (endemic types). 28% of endangered freshwater fish species find habitat in these rivers. The percentage is even higher in regards to bivalves and snails: 40% of all endangered mollusc species in Europe can be found here.

Here is another fact: if the dams are being built, underwater biodiversity will be reduced drastically. 75% of all fish species and 70% of bivalves and snails would not be able to adapt to the new environment and would either die or decrease significantly in numbers.
