The long road to improving the water quality of the Western Bug River (Ukraine) - A multi-scale analysis

- We analyse water quality along a river basin and identify relevant pollution sources.
- Administrative, spatial and temporal scales have to be equally considered for the analysis.
- Wastewater sector is identified as dominant polluter due to deteriorated infrastructure.
- River basin management approach has the potential to overcome conflicting scales.
- To improve water quality substantial reforms and investments are required.

SummaryRiver basin management (RMB) was introduced to combat high levels of water pollution across Ukraine. The Western Bug River provides an example of how water quality is impacted by industrial and domestic wastewater discharges as well as pollution from agriculture and mining activities.The paper draws from a broader interdisciplinary study which aims to outline the sources of pollution within the upper Western Bug River catchment and identify the driving institutional forces behind this enduring environmental problem. The results of this study show that the administrative and spatial scales concerning river catchment management in the Western Bug River basin are not aligned. Furthermore, the temporal scale is often conflicting with the two above mentioned scales. The current political and financial situation of the State, as well as outdated administrative structures hinders effective water governance and results in low water quality. Despite these findings, there is also some evidence that in the longer term the RBM approach could succeed in the Western Bug River, especially if political and legal reforms are properly implemented and enforced.
