Reliable data is crucial for effective policy-making and resource allocation in public services, particularly in sectors like healthcare, agriculture, and HIV/AIDS. However, the dispersion of research papers across the web and grey literature, along with their technical nature, makes it challenging for decision-makers to access and understand critical information. This complexity is especially problematic in low and middle-income countries where data-driven insights are essential for impactful initiatives. Evidence Gap Maps (EGMs) serve as a valuable solution to this challenge. By providing a thematic, visual overview of existing research and highlighting gaps in knowledge, EGMs offer an accessible and centralized knowledge tool that aids policymakers and researchers in making informed decisions, thereby reducing research wastage and driving impactful initiatives.
