Slovenia - Glinscica

OVERVIEW OF DEMO AIM

Slovenian demo (Glinščica catchment area) is situated within the borders of the Municipality of Ljubljana that spans roughly 275 km2 and has a population of 284,000 inhabitants. The demo site covers 7.01% of Ljubljana’s surface area, includes 5 of its districts (Dravlje, Šiška, Rožnik, Vič, Šentvid) and accounts for 8.17% (23,200) of its population, which should all be considered stakeholders in flood management. Originating at 409 m.a.s.l., the headwaters in the steep hill slopes of Toško Čelo give the Glinščica Stream a torrential character which, together with climate change (less frequent, but higher intensity rainfall) and hard regulations, results in regular flooding of the Vič and Rožna dolina districts of Ljubljana. The aim of Slovenian demo is to prepare an integrated catchment management plan for the Glinščica catchment area, valuate the ecosystem services provided by the implementation of restoration and management measures developed within the project and to develop and deploy economic and/or financial instruments (in the form of nature assurance schemes) for effective business models in the field of ecosystem services, green infrastructure and river restoration that would highlight the importance of understanding the value of ecosystems in the long run.

Nature Based Solutions

Since the catchment approach to flood management has never been considered in Slovenia and it is also not existing for the Glinščica Stream, the nature based solutions appropriate for this cases study will be selected as part of the NAIAD project. Considering the natural features of the Glinščica catchment, different NBS will be considered first for the hilly and wooded areas around the source, second for the agriculturally developed middle reaches and third, for the semi- to fully urban areas as the stream reaches the city of Ljubljana. We will focus on NBS that primarily prevent flooding, as this is the main challenge identified for this region, but multiple benefit measures will be sought through ecosystem services approach to further increase the value of ecosystems addressed. In terms of co-benefits the Glinščica catchment is an important source for Ljubljana’s aquifers recharge and irrigation and it is promoted by Municipality of Ljubljana as the green wedge of Slovenia’s capital, so all these services will be considered important co-benefits when selecting the appropriate NBS in the catchment.

Key Stakeholders

The main entities in the Glinščica catchment area affected by floods are the Municipality of Ljubljana, Local Fishing Association - RD Dolomiti, citizens, farmers and companies, including governmental bodies located in the area. However, the most important role in the decision making process have the national agencies within the Ministry for the Environment and Spatial Planning (e.g. Directorate for water of the Republic of Slovenia, Slovenian Environmental Agency, Institute of the Republic of Slovenia for Nature Conservation, etc.) and within the Ministry for Forestry, Agriculture and Fisheries (e.g. Fisheries research institute of Slovenia). So both these groups of stakeholders need to be considered and possibly brought together to realize and work jointly towards a common goal.

Main Outcomes Sought

The Glinščica catchment Integrated Management Plan developed in the project will serve as a case study of the state-of-the-art approaches and concepts to integrated spatial management as well as an example of the most advanced methods available up to date. As such, it will be presented to the relevant stakeholders to start a process of modernization of the outdated and inadequate management practices still applied today.

Methods and data to be used

With the support of the WP5 we will apply the methods prepared in the WPs 2, 3 and 4 to our demo and thus develop locally tailored natural assurance schemes. The specific data requirements will be discussed and selected based on the methodological WPs, but will include data on natural features of the catchment, social and economic impact of floods, biodiversity information, etc.

INSURANCE VALUE OF ECOSYSTEMS

Ecosystem insurance value is a new concept in Slovenian territory. However, several types of insurance against natural disasters exist, for example house and auxiliary facility insurance, insurance of farm animals, crop and stock insurance, insurance of agricultural buildings, machinery and equipment and insurance of business buildings, machinery and equipment. The main insurance companies are Insurance companies Triglav, Sava, Grawe, Generali and Adriatic Slovenica.
