Growth in milk consumption and reductions in child stunting: Historical evidence from cross-country panel data.

Agricultural and food policies are increasingly being tasked with doing more to improve the nutritional status of low-income populations, especially reductions in child stunting. Which specific food sectors warrant additional policy attention is less clear, although a growing body of research argues that increased animal-sourced food consumption in general, and increased dairy consumption specifically, can significantly reduce the risks of stunting, as well as deficiencies in micronutrients and high quality protein. However, experimental research on dairy's impacts on child growth in developing countries is very limited, and non-experimental evidence is confined to cross-sectional surveys.

Exploring the association between agricultural production systems and household diets in Viet Nam.

The government of Viet Nam promotes an integrated and diversified production system that focuses on the symbiotic relationship of livestock, aquaculture, and fruits and vegetables (F&V), locally known as (VAC). The expectation is that this system can prevent soil degradation, while improving dietary quality and income. This study examines the correlation between VAC production systems and diets using cross-sectional data from the 2016 round of the Viet Nam Household Living Standards Survey (VHLSS).

Irrigation improves weight-for-height z-scores of children under five, and Women's and Household Dietary Diversity Scores in Ethiopia and Tanzania.

Evidence on the potential for agricultural intensification to improve nutrition has grown considerably. While small-scale irrigation is a key factor driving agricultural intensification in sub-Saharan Africa, its impact on nutrition has not yet been thoroughly explored. In this study, we assess the impact of adoption of small-scale irrigation in Ethiopia and Tanzania on household and women's dietary diversity, as well as children's nutrition.

Plant different, eat different? Insights from participatory agricultural research.

We examine the association between on-farm production diversity on household dietary diversity in Malawi using microdata collected as part of an environmentally sustainable agricultural intensification program. The program primarily focuses on the integration of legumes into the cropping system through maize-legume intercropping and legume-legume intercropping. Relative to staple cereals such as maize, legumes are rich in micronutrients, contain better-quality protein, and lead to nitrogen fixation.

Analyzing the Drivers of Household Dietary Diversity: Evidence from Burkina Faso.

Background: The diets of millions of poor individuals lack adequate amount of essential nutrients.

Objective: To examine the determinants of household dietary diversity in Burkina Faso and assess whether the choice of a diversity metric matters.

Methods: Using survey data from 2014, we construct 3 metrics-Household Dietary Diversity Score (HDDS), Berry Index (BI), and Healthy Food Diversity Index (HFDI).

Re-examining the effects of drought on intimate-partner violence.

Droughts are associated with several societal ills, especially in developing economies that rely on rainfed agriculture. Recently, researchers have begun to examine the effect of droughts on the risk of Intimate-Partner Violence (IPV), but so far this work has led to inconclusive results. For example, two large recent studies analyzed comparable data from multiple sub-Saharan African countries and drew opposite conclusions.

Welfare effects of weather variability: Multi-country evidence from Africa south of the Sahara.

Climate change and weather variability pose serious threats to food and nutrition security as well as ecosystems, especially when livelihoods depend heavily on natural resources. This study examines the effect of weather variability (shock) occurring up to three planting and growing season prior on per capita monthly household expenditure in rural Tanzania, Uganda, and Ghana. The analyses combine monthly temperature (1950-2013) and precipitation (1981-2013) data with data from several rounds of household surveys conducted between 1998 and 2013.

Trade-offs and synergies between yield, labor, profit, and risk in Malawian maize-based cropping systems.

Land degradation, population growth, and chronic poverty in Eastern and Southern Africa challenge the sustainability of livelihoods for smallholder farmers. These farmers often manage soils depleted of nutrients, apply limited amounts of mineral fertilizer, and take decisions about their cropping systems that involve multiple trade-offs. The rotation of cereals with legumes bears agronomic and ecological merit; however, the socio-economic implications of the cereal-legume rotation require a deeper understanding.

Promotion and Persistence of HIV Testing and HIV/AIDS Knowledge: Evidence From a Randomized Controlled Trial in Ethiopia.

We use data from a randomized controlled trial in Ethiopia and examine the causal effects of HIV/AIDS education, home-based voluntary HIV counseling and testing (VCT), and conditional cash transfers (CCT) for facility-based VCT on HIV/AIDS knowledge and demand for HIV testing. HIV/AIDS education significantly increases HIV/AIDS knowledge but has a limited effect on testing take-up. However, when HIV/AIDS education is combined with either home-based VCT or CCT for facility-based VCT, take-up increases substantially by about 63 and 57 percentage points, respectively.
