From subsidies to nutrition: Investigating effects among cohort children from the Subsidy Reinvestment programme in Nigeria.

This study investigates the effect of a nationwide maternal health programme that targets both demand- and supply-side factors on the nutritional status of children under five years old whose mothers were potentially exposed to the programme. We employed a difference-in-differences approach by matching programme beneficiary facilities to the districts and communities where households reside. The data are drawn from the 2008, 2013, and 2018 rounds of Nigeria's Demographic and Health Surveys (DHS), comprising responses for approximately 120,000 children.

Using mixed methods to construct and analyze a participatory agent-based model of a complex Zimbabwean agro-pastoral system.

Complex social-ecological systems can be difficult to study and manage. Simulation models can facilitate exploration of system behavior under novel conditions, and participatory modeling can involve stakeholders in developing appropriate management processes. Participatory modeling already typically involves qualitative structural validation of models with stakeholders, but with increased data and more sophisticated models, quantitative behavioral validation may be possible as well.
