Forests cover approximately 50% of Estonia’s land area and play a vital role in carbon storage, biodiversity maintenance, and the economy. Climate change poses threats to forest ecosystems through increased drought stress, pest outbreaks, and a higher incidence of wildfires.

Through detailed forest mapping, including species composition, canopy density, and health indicators, authorities can monitor forest vitality and detect early signs of stress or disease. Remote sensing technologies allow for near real-time surveillance of forest conditions, enabling timely interventions such as controlled burns or pest management. Mapping also supports sustainable forest management practices that enhance resilience and carbon sequestration capacity.

Water Bodies: Tracking Lakes, Rivers, and Flood Risks

Estonia is home to thousands of lakes and a dense network of rivers and wetlands, which are integral to its biodiversity and water supply. Climate change impacts such as altered precipitation patterns and temperature increases affect water levels, water quality, and the frequency of floods and droughts.

Geospatial mapping of hydrological features helps track changes in lake and river extents, identify areas prone to flooding, and monitor water quality parameters. This information is essential for water resource management, flood mitigation planning, and protecting aquatic ecosystems. It also supports the design of green infrastructure solutions, such as wetlands restoration, to enhance natural flood defenses.

Urban Zones: Planning for Flood-Resistant Infrastructure and Green Spaces

Urban areas in Estonia, including Tallinn and Tartu, face unique challenges as climate change increases the risk of urban flooding, heatwaves, and air pollution. Mapping urban landscapes at fine scales enables planners to identify flood-prone neighborhoods, heat islands, and areas lacking green infrastructure.

By integrating spatial data on building footprints, drainage systems, and green spaces, city planners can develop targeted strategies to enhance urban resilience. These include constructing permeable surfaces to reduce runoff, expanding urban forests and parks to mitigate heat, and retrofitting buildings for energy efficiency and flood resistance. Furthermore, mapping supports community engagement by providing accessible visualizations of risks and adaptation options.
