Evidence gap maps are an important tool for informing strategic policy, programme and research priorities.
Evidence gap maps (EGMs) consolidate what we know about what works in particular development sectors or thematic areas.
They provide a visual display of completed and ongoing systematic reviews and impact evaluations in a sector or sub-sector, structured around a framework of interventions and outcomes. EGMs are a useful tool for development decision makers, researchers and donors looking for evidence to inform programme investments and identify where there is an urgent need for more research or rigorous evaluation.
3ie’s interactive online platform allows users to explore the evidence included in a particular EGM, including links to each included study and review.

Evidence gap map on social, behavioural and community engagement interventions
The purpose of this gap map, developed in collaboration with WHO and PMNCH, is to assess the evidence available on social, behavioural and community engagement interventions related to reproductive, maternal, newborn and child health programmes in low and middle-income countries. This map was produced by the World Health Organisation and 3ie. Financial support was provided by the Partnership for Maternal, Newborn & Child Health (PMNCH), the Norwegian Agency for Development Cooperation (NORAD), and the United States Agency for International Development (USAID).
The EGM includes both completed and ongoing studies.
Map of maps
The purpose of this map of evidence maps, funded by Centre of Excellence for Development Impact and Learning and The Department for International Development UK, is to present the findings related to sustainable development in low-and middle-income countries. The authors catalogued evidence maps within a framework of intervention sectors adapted from the World Bank categorisation and outcomes classified according to the Sustainable Development Goals.
Agricultural risk and mitigation gap map
The purpose of this evidence gap map, funded by The Department for International Development UK, is to assess the evidence on agricultural insurance interventions that aim to improve smallholder farmer resilience in low-and middle-income countries.
State-society relations evidence gap map
This evidence gap map (EGM) consolidates evidence on interventions to improve state-society relations in low- and middle-income countries. The map draws on a systematic search and inclusion/exclusion of studies to take stock of the volume and characteristics of evidence published between 2000 and 2016.
Science, technology, innovation and partnerships evidence gap map
This evidence gap map, part of a project funded by the US Global Development Lab at USAID, assesses the impact evaluation and systematic review evidence base for how science, technology, innovation and partnerships accelerate development outcomes in low- and middle-income countries.
Adolescent sexual and reproductive health evidence gap map
This evidence gap map, part of a project funded by the William and Flora Hewlett Foundation, assesses the evidence available on the effects of adolescent sexual and reproductive health programming in low- and middle-income countries.
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.
Water, Sanitation and Hygiene evidence gap map
This evidence gap map includes 23 systematic reviews and 139 impact evaluations of WASH interventions. Evaluations collected data on health and non-health impacts. 3ie completed the map in 2014 and we will update it in early 2018.
