The document discusses changes and challenges in Zambia's nutrition policy environment since 1990 based on a mixed methods study. Key findings include: - Stunting in children under 5 has declined significantly from 1992 to 2014 but remains high at 40%. - Future studies on nutrition drivers should combine health and agricultural data and collect dietary data from different populations. - Zambia now has coherent nutrition policies across sectors but needs monitoring to ensure new policies still prioritize nutrition. - Strengthening the capacity of "boundary spanner" organizations and the three key nutrition institutions could help drive further progress. - More work is needed to strengthen intersectoral coordination at both national and local levels.
