Ocean Evidence Gap Map (2021-2022)


We are living through an era of rapid social and environmental change, particularly for the world’s oceans. This rate of change is seemingly matched by the generation of information (and misinformation) regarding potential solutions to achieve sustainability changes across scales. 

Evidence synthesis is a powerful tool to draw insights from multiple sources to guide evidence-based decision-making and identify areas where more targeted research is needed. Nonetheless, traditional approaches to synthesize evidence are inadequate to meet the needs of today’s end-users. 

Evidence synthesis research is usually discipline-specific as well as time- and resource-intensive, and it involves software that is inaccessible to many. Over the last few years, researchers have increasingly used machine learning and a broad mix of proprietary and open-source applications for evidence synthesis. Yet many of these tools are developed in silos with little effort to integrate approaches, and they still require considerable time, expertise and resources to implement. To support ocean conservation science and practice, there is a need for resource-efficient synthesis approaches that are accurate, accessible and reproducible. 

Project Description 

This project will convene a network of synthesis experts and end-users from scientific, philanthropic and implementing organizations to pursue several aims, including to:

  • Assess the efficiency, performance and usability of existing machine learning tools and approaches for evidence synthesis
  • Develop an integrated assemblage of efficient and accessible tools and approaches – known as an evidence pipeline – to support future evidence synthesis research in various sustainability fields
  • Utilize the evidence pipeline to advance the marine conservation evidence base in collaboration with practitioners and policymakers

The project team will identify and prioritize challenges and needs for progressing cost-effective evidence synthesis and potential candidate state-of-the-art solutions. Team members will focus on methods developed by previous teams, identifying ways to facilitate integration of a diverse array of open-source tools and approaches. 

Next, the team will evaluate the efficiency, performance and usability of various candidate tools for improving parts of the synthesis process. The output will be the development of an evidence pipeline to support efficient and robust synthesis from search string development through reporting, to be shared with the broader academic and practitioner community.
