Nutritional Interventions and Food Security An Empirical Analysis of CSB, LNS, and Ration Cycles in Haiti (WFP)

Context and Objectives

Haiti continues to face a protracted food security crisis driven by structural poverty, high market dependence,
macroeconomic volatility, and recurrent climatic shocks, leaving most vulnerable households reliant on markets
at a time of severely constrained purchasing power and persistently high food prices. In this context,
nutrition‑sensitive assistance—particularly through Corn–Soy Blend (CSB) and Lipid‑based Nutrient Supplements
(LNS)—remains essential to stabilizing household food consumption, yet constrained resources and access
challenges require careful trade‑offs between ration size, duration, and distribution regularity. Drawing on a
multinomial logit analysis of 6,601 households, this report shows that program design and delivery cadence
are decisive and provides decision‑oriented evidence to guide donor investments toward sustained, predictable,
and well‑targeted assistance, prioritizing multi‑cycle continuity and reliable delivery over short‑term volume to
achieve durable and cost‑effective food security gains in Haiti.
