1. Network Based Tools and Indicators for Landscape Ecological Assessments, Planning, and Design
Abstract : Land use change constitutes a primary driving force in shaping social-ecological systems world wide, and its effects reach far beyond the directly impacted areas. Graph based landscape ecological tools have become established as a promising way to efficiently explore and analyze the complex, spatial systems dynamics of ecological networks in physical landscapes.

2. The influence of multiscale hyporheic flow on solute transport : Implications for stream restoration enhancing nitrogen removal
Abstract : Stream water that flows into and out of streambeds is called hyporheic exchange flow (HEF).It continuously interacts with groundwater and thereby affect the water quality of local streamreaches as well as downstream recipients by providing an environment where solutes andenergy can be retained and degraded.

3. On the contribution of forest bioenergy to climate change mitigation
Abstract : Greenhouse gas (GHG) emissions have to be drastically reduced to keep global warming below 2 degrees. Bioenergy can play a role in climate change mitigation by substituting for fossil fuels. READ MORE

4. Estimation of forest parameters using 3D satellite data : stereogrammetry, radargrammetry and interferometry
Abstract : Accurate data about the forest are needed both in climate research and forest management planning. This thesis focuses on using different types of three-dimensional (3D) satellite data sources to accurately estimate forest variables, primarily above-ground biomass (AGB) and tree height (H).

5. Harvesting from land and sea : Social relationships, trade networks, and spatial connectivity in changing social-ecological systems
Abstract : In the era of global change, the connectivity of aquatic and terrestrial food production systems across spatial scales is increasing. At the same time, diverse actors that participate in food systems, from production to consumption, face the need to adapt their daily activities to an increasingly changing context. READ MORE
