The Impact Assessment and Public Policy Division serves as a critical bridge between grassroots innovations and systemic change by evaluating their societal influence and shaping policies to amplify their reach. At the heart of its mission is conducting in-depth research on diverse innovation ecosystems, analyzing policy gaps, challenges, and opportunities to design interventions that empower grassroots innovators. The division strives to construct evidence-based resources such as policy briefs, white papers, and innovation roadmaps, offering actionable insights for strengthening support frameworks. It is dedicated to curating a dynamic repository of case studies and impact reports, documenting how grassroots technologies drive socio-economic progress, from rural livelihoods to environmental sustainability. To foster collaboration, the division organizes policy dialogues, seminars, and roundtables, convening innovators, industry experts, academics, and policymakers to co-create inclusive solutions. Central to its work is developing rigorous impact assessment frameworks to evaluate the technical viability, scalability, and societal benefits of NIF-supported innovations, ensuring their alignment with community needs. By synthesizing research into quality publications, the division translates grassroots success stories into tools for advocacy, education, and decision-making. Ultimately, this division not only measures the ripple effects of innovation but also champions policies that transform grassroots ingenuity into engines of equitable development.
