The specific objective of the project is “Improved ecological state and water quality in the cross-border rivers Koitajoki and Tohmajoki”. The objective is in line with Priority 3: Clean and comfortable region to live: Element 4: Using nature in the promotion of health and wellbeing, because the project aims to produce updated data about the pollution status of the cross-border rivers for establishing management plans to support, restore and protect biodiversity in the river areas. This supports maintenance of recreational activities in nature that promote health and wellbeing of the locals and tourists on both sides of the border.
