Evidence Gap Map

What is an evidence gap map?

An evidence gap is a thematic collection of empirical knowledge in a domain or discipline. They help clarify and map key concepts that underpin a research area. They also help researchers and decision-makers: 

  • Identify overall gaps in the research and evidence base;
  • Report on the types of evidence, such as observational studies, impact evaluations–that are being published in the field;
  • Capture how a research field is evolving, and whether there is enough evidence in any one area to evaluate more specific questions;
  • Explore the indicators and methods of analysis currently being used in the domain

How is an evidence gap map created?

For studies to be included in the evidence gap map, they must be interventions that have been tested with relevant populations, as compared to research and development that might be promising, but is ultimately unproven on the ground. In addition:

  • A targeted population. Ideally including description and rationale for why a particular user group was asked to participate in the study;
  • Geographies of interest. Country must be a recipient of Official Development Assistance (ODA) Funds
  • Identifiable interventions or services. Ideally a clearly defined digital agricultural service, program or product that was introduced and used by a target population;
  • Measurement of outcomes. A description and measurement of the impact(s) of using the services.
