Success and limiting factors:
Main success factors include:
- The case study is a good example where cooperation of various stakeholders was key for a comprehensive approach and a commonly accepted solution;
- The engagement of various stakeholder during the various phases of the project and decision-making process; The Cost-Benefit Analysis (CBA) and Multiple-Criteria Decision Analysis (MCDA) were helpful tools in this process;
- Technical project of adaptation measures have been initiated by the Klaipėda city municipality, being realized in a first stage of the Smeltalė River Park;
- Including climate change adaptation measures into existing development plans of local municipalities (Klaipėda city development plan).
Budget, funding and additional benefits:
The preliminary costs of dyke system on both watersides of the Smeltalė river is about 5 million Euros (including river bed canalization works, but without land taxes). The calculations were made by Vilniaus Hidroprojektas Ltd. in 2010.
Moreover a survey for stakeholders about Cost-Benefit Analysis (CBA) and Multi Criteria Decision Analysis (MCDA) was prepared and distributed. It consisted of 8 questions about possibilities to use these methods for the Smeltalė River basin. A damage cost assessment scheme for the Smeltalė river basin flood events was made according to respondents’ answers. The most feasible and most important criteria are related to infrastructure and building value assessment. Meanwhile, ecological and social criteria are quite difficult to assess. The nine different MCDA methods were used to assess the adaptation measures. According to the 7 of 9 MCDA methods the best adaptation measure appears to be – the complex embankments and dykes system on both watersides of the river. Meanwhile, the most favourable measure gleaned from the questionnaire is the best choice using only 2 of 9 MCDA methods – the dyke system on both watersides of the Smeltalė river.
