Progress in Water, Sanitation and Hygiene (WASH) coverage and potential contribution to the decline in diarrhea and stunting in Ethiopia

Inadequate safe water supply and poor sanitation and hygiene continue to be important risk factors for diarrhoea and stunting globally. We used data from the four rounds of the Ethiopian Demographic and Health Survey and applied the new World Health Organization (WHO)/UNICEF Joint Monitoring Program (JMP) service standards to assess progress in water, sanitation and hygiene (WASH) coverage between 2000 and 2016. We also performed an age-disaggregated pooled linear probability regression analysis followed by a decomposition analysis to determine whether changes in WASH practices have contributed to the changing prevalence of diarrhoea and stunting in children under 5 years of age. We observed a significant increase in the coverage of safe drinking water and adequate sanitation facilities over the period. At the national level, the use of a basic water source increased from 18% in 2000 to 50% in 2016. Open defecation declined from 82% to 32% over the same period. However, in 2016, only 6% of households had access to a basic sanitation facility, and 40% of households had no handwashing facilities. The reduction in surface water use between 2000 and 2016 explained 6% of the decline in diarrhoea observed among children aged 0–5 months. In children aged 6–59 months, between 7% and 9% of the reduction in stunting were attributable to the reduction in open defecation over this period. Despite progress, improvements are still needed to increase basic WASH coverage in Ethiopia. Our findings showed that improvements in water and sanitation only modestly explained reductions in diarrhoea and stunting.

Joint Forces: The Impact of Intrahousehold Cooperation on Welfare in East African Agricultural Households

Joint Forces: The Impact of Intrahousehold Cooperation on Welfare in East African Agricultural Households

In low- and middle-income countries, poor cooperation between members of smallholder agricultural households may lead to inefficient allocation of productive resources. This study estimates the causal mediating effects of cooperation between spouses on household welfare and public goods provision in Ugandan and Tanzanian monogamous smallholder coffee farming households. The random encouragement to participate in an intensive training program coaching couples in farming as a household enterprise and participatory intrahousehold decision making, which stimulates cooperation and, in turn, household welfare and public goods provision, enables estimating causal mediating effects while avoiding challenges of endogeneity. Spousal cooperation has positive mediating effects on household welfare, measured by total household income per capita and food security, and on household public goods provision, measured by the adoption intensity of agronomic practices and use of improved seed for food crops. Spousal cooperation has larger effects on total household income per capita with longer duration of marriage.

Predicting poverty with vegetation index

Predicting poverty with vegetation index

Accurate and timely predictions of the poverty status of communities in developing countries are critical to policymakers. Previous work has applied convolutional neural networks (CNNs) to high‐resolution satellite imagery to perform community‐level poverty prediction. Although promising, such imagery has limitations in predicting poverty among poor communities. We provide the first evidence that a publicly available, moderate‐resolution vegetation index (the normalized difference vegetation index [NDVI]), can be used with CNNs to produce accurate poverty predictions contemporaneously among poor communities heavily dependent on agriculture. We also show that the NDVI can effectively detect consumption variation over time. To our knowledge, this is the first attempt to use remote sensing data to predict future‐period consumption expenditure at the community level.

Virtual Event – Local vs Global? The role of trade in building food system resilience

As the COVID-19 pandemic continues to wreak havoc on the global economy and put pressure on food supply chains, debate has resurged about the role of trade in protecting food security. Though food supply chains have proved fairly resilient during the outbreak, many countries have faced both severe disruptions in supply and shifts in food […]
