All about alpine rivers - a sort of ...

These days I've found a nice GIS datatset of alpine rivers in Tyrol (running waters as vector lines, many point informations like hydropower plants, sources etc.). Moreover the dataset is creative commons licensed (Attribution 3.0 Austria (CC BY 3.0 AT)).

Data source: Land Tirol - data.tirol.gv.at (GIS: GRASS GIS; DEM: SRTM)

Maybe it's already out there, it would be fine to have such a detailed river/hydro dataset for the entire Alps, particularly as a base for an open minded discussion about new hydropower plants nowadays.

And keep the idea of sustainable water use in the sense of the Alpine Convention (1, 2, 3, 4, 5, 6) , Natura 2000 and Water Framework Directive in mind.

Natura 2000 and land cover changes - how to manage?

Natura 2000 is the centrepiece of EU nature and biodiversity policy. It's an EU-wide network of protected areas established under the Habitats Directive and Bird Directive.

The Corine programme (Coordination of Information on the Environment) has established a computerised inventory on the land cover (100x100m) in Europe and delivers summaries for the period 1990-2000 and 2000-2006.

Some analysis results by intersecting the Natura 2000-protected areas and lande cover changes in Austria for these two periods (processed in GRASS GIS).

1990 - 2000: 122 km2 land cover change within Natura 2000-protected areas Austria

Natura 2000-sites and landcover changes 1990-2000 (DEM: SRTM)

• Glacier and perpetual snow to open spaces with little or no vegetation: 72,6%
• Non-irrigated arable land, pastures, natural grassland and land principally occupied by agriculture, with significant areas of natural vegetation to artificial surfaces: 6,2%
• Non-irrigated arable land, pastures to forest: 1,7%

2000 - 2006: 63 km2 land cover change within Natura 2000-protected areas in Austria

Natura 2000-sites and landcover changes 2000-2006 (DEM: SRTM)

• Glaciers and perpetual snow to open spaces with little or no vegetation: 53,3%
• Non-irrigated arable land, pastures, natural grasslands and land principally occupied by agriculture, with significant areas of natural vegetation to artificial surfaces: 3,6%
• Pastures and natural grassland to forests: 0,8%

We are currently witnessing a steady loss of biodiversity (1) (2). Land cover/use and biodiversity are connected, especially in the cultural landscape (3). As shown by the results, two main drivers for such changes can be identified: changes in "natural"/physical factors (e.g. temperature, preciptation - climate change) and human activities.

The European Commission adopted the EU biodiversity strategy 2020 to halt the loss of biodiversity and ecosystem services in the EU by 2020.

Protected areas may be considered as nucleus of a sustainable development, though common trends of landuse changes (associated with influence on biodiversity) seems to occur also inside.

How to manage these processes (4) (5) (6)?
