WASH and Nutrition Synergies: The Case of Tunisia
基于联合国儿童基金会营养概念框架，估计了水、环境卫生和个人卫生投资与儿童发育迟缓的关联，发现不同居住地和贫富群体需要不同的干预组合，为突尼斯制定针对性营养策略提供依据。
This paper develops a simple econometric strategy to operationalise the United Nations Children’s Fund’s (UNICEF’s) conceptual framework for nutrition. It estimates the extent to which child stunting correlates with investments in water, sanitation, and hygiene (WASH) across population groups (poor and nonpoor) and residence (urban and rural). Moving away from estimating single intervention marginal returns, the empirical framework of intervention packages is tested in Tunisia, a country with notable but uneven progress in reducing stunting. A successful nutritional strategy will thereby require mapping the distinctive intervention packages by residence and socio-economic status, away from universal policies, that more strongly correlate with reduction in stunting.
