Balancing river ecosystems and hydropower requirements

The purpose of SHARE is to develop, test and promote a decision support system (DSS) to merge, on an unprejudiced base, both river ecosystems and hydropower requirements. The project openly pursues integrated river management aims.

The approach: merging scientific tools, local specificities and operational requirements

 Future available tools



Software & online tools

to weight and balance all river-related issues.

A guidebook for policy-makers

to take transparent and well informed decisions where hydropower is involved, thanks to a multicriteria approach (MCA) methodology that will include scientific knowledge related to HP and river management.

The MCA will be applied to assess different management alternatives where a single-criterion approach (such as cost-benefit analysis) falls short, especially where environmental, technical, economic and social criteria can’t be quantified by monetary values.

Databases focussed on the alpine region

to quickly identify applicable laws and competent authorities, from a local to an international scale;

to characterize alpine rivers typologies and to assess their vulnerability to hydropower installations;

to classify scenarios of water use optimisation.

A set of generally applicable and comparable indicators & monitoring standards

to assess hydropower effects on dissimilar water bodies’ health.

The partnership

SHARE is supported and implemented by 13 partners (universities, local authorities, NGOs). The leading partner is ARPA (Regional Agency for Environment) Valle d’Aosta. The project partnership embodies 5 different alpine countries & hydrosystems, profiles, status, end users, networks, expertises and concerns of all stakeholders in water management issues, such as: regional and local authorities, policy makers, hydropower companies, water authorities, nature protection agencies, NGOs, water suppliers. They can take part in and benefit from the project results as members of the national Permanent Technical Panel. The official observers represent the links with the outside of the project.

The project


SHARE – Sustainable Hydropower in Alpine Rivers Ecosystems – is a running project in line with the European Territorial Cooperation Alpine Space programme 2007-2013. As such it has been early approved and co funded by the European Regional Development fund. The project will formally take place from August 2009 to July 2012.
