Impact of access to water and sanitation services on educational attainment

Abstract

a b s t r a c tChildren are prone to the contagion of waterborne diseases without adequate water and sanitation services. When not sick, children and their caregivers without proper access to such services have to allocate their leisure time in order to meet their water and sanitation needs. It is through these health and leisure time use changes that access to water and sanitation services impacts the educational attainment of children. This paper proposes a household utility maximization model in which access and sanitation services determine the child's health, which in turn affects the child's education and the household welfare.Comparative statics indicate that households consider the health gains to the market value of their leisure time, and the changes in the consumption of other goods. The model is applied to data from Brazil. In order to sort out the endogeneity between provision of water and sanitation services, and educational attainment, the paper uses an instrumental approach, based on the technical features of the water systems and an instrument that measures a proxy of water availability within the municipality territory. Estimates suggest that access to water and sanitation services has a positive and significant effect on schooling, when measured by the completed number of school years. These positive effects call for the expansion of the laggard sewerage systems in the country, both at home and at school.

Improved yet Unsafe: An Aquatic Perspective of Indian Infant Mortality

“…Mújica, Haeberer, Teague, Santos-Burgoa, and Galvão (2015) mentioned that equal right to improved drinking water sources among the American countries is of utmost importance to reduce infant mortality. Ortiz-Correa, Resende Filho, and Dinar (2016) opined that access to improved water sources along with sanitation are major determinants of infant mortality. Patel et al (2015) informed that lack of coverage of improved drinking water sources is one of the major causes of infant mortality in India.…”

“…According to the United Nations [4], water scarcity already affects every continent [5]. More than one billion people currently lack access to safe drinking water, and around 2.5 billion people lack access to improved sanitation.…”

Heading towards an unsustainable world: some of the implications of not achieving the SDGs

“…Clean water and proper sanitation would be unattainable for billions Due to the consequences of not reaching other SDGs as well (including increased infrastructure demand and climate consequences) people could be displaced and experience water stress. This situation would certainly affect education and health [ 45 , 46 ], among other sustainability goals By not increasing considerably the share of renewable energy in the global energy mix, the consequences would be mainly related to climate (e.g. substantial carbon emissions and reduced air quality) [ 47 ] in addition to probable conflicts for the consumption of fossil fuels.…”
