The Biodiversity Integrated Assessment and Computation Tool (B-INTACT)

The Biodiversity Integrated Assessment and Computation Tool (B-INTACT) uniquely seeks to provide a thorough biodiversity assessment of project-level activities in the Agriculture, Forestry and Other Land Use (AFOLU) sector, taking on both a quantitative and a qualitative approach. The quantitative approach considers a set of relationships for anthropogenic impacts on biodiversity from land use changes, habitat fragmentation, infrastructure and human encroachment, expressed in the mean species abundance (MSA) metric. Non-quantifiable impacts to biodiversity from project activities are assessed with a qualitative appraisal.

The tool aims to (i) quantify the biodiversity impact of various investments at project and policy-level using globally recognized environmental assessment methodologies; (ii) provide decision-makers with a set of policy indicators to help making informed decisions; (iii) extend the scope of environmental assessments to capture biodiversity concerns which are not accounted for in conventional carbon pricing; and (iv) support countries in accessing funds from international financial institutions and mechanisms to fund projects, programmes and policies.


The quantitative methodology is largely based on the Global Biodiversity (GLOBIO) Model Version 3.6 developed by the Netherlands Environmental Assessment Agency (PBL).

The social value of biodiversity is computed using summary values extracted from the Ecosystem Service Valuation Database (ESVD).
