Vesistöhoito

Vesistöhoito, meaning water body management or aquatic ecosystem management, refers to the systematic planning and implementation of measures to protect, restore, and sustainably utilize inland water bodies. This encompasses lakes, rivers, streams, and groundwater, and their associated ecosystems. The primary goals of vesistöhoito are to ensure good ecological status, maintain biodiversity, and provide ecosystem services such as clean water for human consumption, recreation, and supporting aquatic life.

The practice involves a range of activities. Hydrological management might include regulating water flow, managing water levels, and controlling invasive species that disrupt natural water dynamics. Water quality improvement is a significant component, involving the reduction of pollution from agricultural runoff, industrial discharge, and wastewater. This can be achieved through measures like improving wastewater treatment, promoting sustainable land use practices in surrounding areas, and restoring riparian zones.

Ecological restoration efforts often focus on improving habitat conditions for native species. This can involve removing artificial barriers to fish migration, creating or restoring wetlands, and reintroducing native vegetation. Monitoring is a continuous process, with regular assessments of water quality, biodiversity, and the effectiveness of implemented measures. Vesistöhoito also considers the social and economic aspects, balancing environmental protection with human needs and activities, such as fishing, boating, and water abstraction. The overarching aim is to create resilient and healthy aquatic ecosystems for present and future generations.
