Advocacy coalitions and the transfer of nutrition policy to Zambia por Harris, Jody

“…Analysis was based on two established political science theories: policy transfer theory and the Advocacy Coalition Framework. Policy changes in Zambia are shown to result from the international community’s nutrition agenda, transferred to national policy through the normative promotion of certain ways of understanding the issue of malnutrition, largely propagated through advocacy, technical assistance and funding. …”

Trust, hope, and collective action in fragile political settings: a qualitative comparative analysis of water user groups in Tunisia por Bhalla, S., Garrick, D., McDermott, C. L.

“…Specifically we find that: (1) social cohesion and the expectation that other water users stick to local, often informal, rules were found to increase collective action, i.e. fee recovery, under systemic fragility; (2) resource scarcity, i.e. aquifer depletion, can serve as a driver of both conflict as well as cooperation, depending on conjoint social-ecological interactions; and, finally, (3) conflict is more frequently associated with low-hope environments, where users are unable to perceive the possibility of positive system change. These insights seek to inform more realistic policy reforms that are sensitive to a fragile water governance system prone to social unrest.…”
