Evidence gap maps are an important tool for evidence-informed policies and strategic research prioritisation.
Evidence gap maps (EGMs) consolidate what we know about what works in particular development sectors or thematic areas.
3ie’s EGMs identify evidence from systematic reviews and impact evaluations and provide a graphical display of areas with strong, weak or non-existent evidence on the effects of development programmes and initiatives.
EGMs are useful to policymakers and development practitioners looking for evidence to inform policies and programmes. For donors and researchers, these maps can help identify areas where there is an urgent need for more rigorous research evidence.
3ie has recently developed a new interactive and dynamic online platform which allows users to explore the evidence included in a particular EGM, with links to user-friendly summaries of all studies.

Forest Conservation Gap Map
This evidence gap map examines the high-quality evidence available in the area of forest conservation in low-and middle-income countries. Our clearest finding is that there a paucity of high-quality evidence in areas significant for policy such as the effect of forest-related climate change policies, trade laws and management, or education and awareness campaigns on environmental and social outcomes in forests.
Land Use Change and Forestry Evidence Gap Map
The purpose of this evidence gap map is to assess the evidence available on the effects of land-use change and forestry programmes on greenhouse gas emissions and human welfare outcomes. Our clearest finding is that there is a major gap in the evidence addressing effects on both emissions and human welfare outcomes, including food security. Moreover, few studies measured greenhouse gas emissions or food security directly.
Youth and transferable skills Evidence Gap Map
The purpose of this evidence gap map is to provide easy access to the best available evidence on the outcomes of transferable skills programming for youth in low- and middle-income countries and to highlight where there are important gaps in this evidence base. Transferable skills, often referred to as soft, non-cognitive or life skills, provide youth with the tools and confidence to succeed in term of employment, health and personal well-being.
Evidence for Peacebuilding Evidence Gap Map
The purpose of the evidence map is to provide easy access to the best available evidence on the outcomes of peacebuilding interventions in conflict affected settings in low- and middle-income countries. Interventions were mapped in five thematic areas including legitimate politics, security, justice, economic foundations and revenues and social services.
Water, Sanitation and Hygiene Evidence Gap Map
The purpose of this evidence map is to provide easy access to evidence on the effects of water, sanitation and hygiene interventions in low- and middle-income countries. The map includes both impact evaluations and systematic reviews of interventions that include provision of water supply and safe drinking water, sanitation and hygiene-related education, as well as sector-level programmatic interventions to improve governance and access.
Primary and Secondary Education Evidence Gap Map
This evidence gap map aims to facilitate evidence-informed decision making in education by providing easy access to all existing systematic reviews and impact evaluations of the effects of education interventions. The map includes evidence on interventions designed to improve access to education and learning outcomes for primary and secondary school children in in low- and middle-income countries.
Productive Safety Nets Evidence Gap Map
This evidence gap map consolidates impact evaluation and systematic review evidence on the effects of productive social safety net programmes on extreme poverty and related outcomes in low- and middle-income countries. Productive social safety nets are safety net programmes that include livelihood or income generating components to expand market opportunities for the extreme poor.
