Articulating and Assessing Biodiversity Impact

The Biodiversity Impact Assessment Framework (referred to as BIAF in this report) is based on assessing three components of biodiversity: extent, condition and importance. It involves identifying the impact pathways that directly or indirectly link planned or current activities to one of the five factors causing biodiversity loss (change in sea and land use, direct exploitation, climate change, pollution and invasive species).

The report explains in more detail the BIAF methodology and some of the challenges involved, and summarises four case studies to illustrate its application. The pilot application of the BIAF (including the four case studies described in this document) shows that the method provides plausible and interpretable results to support decision-making.
