Gillian Petrokofsky

GP2-1Dr. Gillian Petrokofsky focuses on action research to support evidence-based decision making in forestry and land-use. She works in multidisciplinary teams to engage communities of interest, who collectively contribute to exploring and solving contemporary problems facing the sector.

Evidence Based Forestry

Gillian Petrokofsky leads a collaborative project co-ordinated by the Center for International Forestry Research (CIFOR), with its international partners to establish the Evidence-Based Forestry (EBF) Initiative from 2012-2015 and continues to work on outputs from that initiative with scientists in Partner insistutions – CATIECIRADICRAF and IUFRO and universities across the world. The Initiative reflects the Partner institutions’ leading roles in generating evidence for policy processes about forests and forestry, defined broadly in the contexts of both landscapes and sustainable development. The EBF Initiative was established to facilitate and promote use of systematic methods for informing decisions and actions about forests and forestry. The EBF initiative is supported with resources contributed by UK DfID’s Know For Program Grant.


To date, the EBF initiative work has established a mechanism for introducing evidence-informed frameworks  to conduct systematic reviews and systematic maps that conform to standards of existing collaborations. Protocols and completed reviews are published in Open Access peer-reviewed journals, and summaries for policy makers and other stakeholders are published in a variety of accessible ways, inlcuding Policy Briefs, blogs and podcasts. An international project – T20Q (Top Twenty Questions for Forestry & Landscapes) – to determine high priority research and policy questions ran during 2014 in collaboration with the Sylva Foundation, an established partner of the Oxford Long-term Ecology Laboratory and Biodiversity Institute. Outputs from that project are being used to inform future priorities for systematic reviews.
