Thesis Topic: Offsetting approved harmful anthropogenic impacts in the 21st century – Insights into global offsetting practices, habitat banking as an alternative offsetting mechanism and application of habitat enhancement in northern boreal lake systems
Seminar Abstract:
Land-use change via human development is a major driver of biodiversity and habitat area loss as well as ecosystem function impairment. To reduce these impacts, billions of dollars are spent on environmental offsets, to compensate for authorized negative impacts. This research program evaluated offsetting success across different temporal and spatial scales with the focus on aquatic ecosystems and under consideration of special use cases like residual harm and habitat banking. Data based systematic reviews and model development were complemented by habitat enhancement field studies in northern boreal lake systems. Field studies focussed on benefit provision of large woody debris for aquatic communities measured in the northern boreal beta-diversity and habitat utilization. Studies evaluating offset project effectiveness and individual mechanisms, remain rare. Our conducted studies can be used to inform and improve current best practice, identify future research and policy needs and guide regulatory agencies and stakeholders alike.
