Estimating multidimensional development resilience

Estimating multidimensional development resilience

Existing measures of resilience are typically based on a single well-being indicator. This is problematic in contexts where households face deprivations across multiple dimensions. We develop a multidimensional resilience measure, integrating probabilistic moment-based resilience measurement approaches with multidimensional poverty measurement methods. Applying these to household panel data from Ethiopia, we show that univariate and multidimensional resilience measures based on expenditure-based poverty, dietary diversity, and livestock asset holdings can yield varied inferences on the ranking of households as well as potential impact of development interventions. Univariate resilience measures constructed using consumption expenditure, dietary diversity and livestock asset holdings show distinct temporal and spatial distributional patterns. But while univariate measures are weakly correlated with one another and with different well-being metrics, multivariate measures exhibit much stronger rank correlations. When we contrast univariate measures of resilience to multidimensional measures of resilience, we find that the latter vary less over the study period; multidimensional resilience measures seem to capture more “persistent or structural” vulnerability and associated capacity of households. We also demonstrate the differences in these univariate and multivariate measures, including the potential of the composite multidimensional resilience measures for supporting targeting processes.

Does small-scale irrigation affect women’s time allocation? Insights from Ethiopia

Does small-scale irrigation affect women’s time allocation? Insights from Ethiopia

Small-scale irrigation (SSI) interventions have received increasing attention as a potential pathway for women’s empowerment in sub-Saharan Africa. One key aspect of women’s empowerment that SSI can influence is women’s time burden. Hypothesized benefits of SSI for women are less energy exertion and reduced labor in agriculture. Yet, these hypotheses have not been tested empirically. We explore how household adoption of different SSI technologies affects the time allocation of women in the household, using two rounds of intrahousehold panel survey data from Ethiopia. Two different approaches are used to address potential endogeneity issues related to time-constant and time-varying factors that may be correlated with both SSI and time use: an instrumental variables-correlated random effects approach and a fractional multinomial logit-correlated random effects with control function approach. The results suggest that household use of SSI in general is associated with an increase in women’s leisure time. The results further suggest that household use of motor pumps is associated with an increase in women’s leisure time and reductions in the time they spend on farming and personal care. Given that women often provide the labor for irrigation using manual, labor-intensive methods, such as watering cans, buckets, or hand- or foot-powered treadle pumps, the results suggest that SSI using motorized methods has the potential to free up women’s time in farming and enable more leisure time. These findings have broad implications for women’s empowerment and labor allocation. Future research using new and more comprehensive data could explore the mechanisms for the findings in this study and determine if SSI enables women to improve their ability to allocate their time to activities they prefer.

Using a list experiment to measure intimate partner violence: Cautionary evidence from Ethiopia

Using a list experiment to measure intimate partner violence: Cautionary evidence from Ethiopia

While indirect response methods are increasingly used in surveys to measure sensitive behaviours such as intimate partner violence, important questions persist around how respondents understand and react to these methods. This article presents evidence from a list experiment measuring multiple forms of intimate partner violence in rural Ethiopia. We find that the list experiment does not generate estimates of intimate partner violence that are higher than direct response questions; rather, prevalence estimates using the list experiment are lower vis-à-vis prevalence estimates using the direct reports, and are sometimes even negative. We provide suggestive evidence that this pattern may reflect ‘fleeing’ behaviour by respondents who do not wish to be associated with statements indicating their exposure to intimate partner violence.

HER+ Sustainable Land Management Trial in Ethiopia: Endline Survey

2025International Food Policy Research Institute
Details

HER+ Sustainable Land Management Trial in Ethiopia: Endline Survey

The HER+ Sustainable Land Management Study is a randomized controlled trial evaluating a bundled intervention that provides training and inputs (including 4-6 fruit tree seedlings, vegetable seeds, and tools) to encourage extremely poor rural Ethiopian households to adopt three complementary sustainable land management (SLM) practices: fruit tree planting, composting, and home gardening. The baseline survey was conducted in May-June 2023, followed by the intervention, with the endline study completed in May-June 2024. The study covers 95 sub-districts, with 20 households randomly selected in each sub-district from among beneficiaries of the Productive Safety Net Program (PSNP) who met pre-specified eligibility criteria, resulting in a total sample of 1,900 households. The data presented here is from the endline survey.

Simulated Future Climates for Ethiopia Using MIT-IGSM HFDs Based on CMIP5

Simulated Future Climates for Ethiopia Using MIT-IGSM HFDs Based on CMIP5

The dataset consists of high-resolution climate projections spanning 50 years, capturing spatial and temporal variations in temperature, precipitation, and extreme weather events. These climate inputs were combined with agricultural models to simulate the frequency, intensity, and impact of weather events on the yields of key crops, such as maize, in Ethiopia. It integrates hybrid frequency distributions (HFDs) from the Massachusetts Institute of Technology Integrated Global Systems Model (MIT-IGSM) with detrended gridded historical climates from Princeton Global Forcings. Using a Gaussian quadrature routine, 455 representative climate scenarios were selected for Ethiopia under each emissions scenario (SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5). This comprehensive dataset provides critical insights into the risks posed by climate change to food security and serves as a valuable resource for researchers and policymakers aiming to develop adaptive strategies for sustainable agriculture.

SPIR II Group Problem Management Plus (gPM+) Baseline Survey in Tigray, Ethiopia

Details

SPIR II Group Problem Management Plus (gPM+) Baseline Survey in Tigray, Ethiopia

This study’s objective is to evaluate the effectiveness of a low-cost psychotherapy intervention, group Problem Management Plus (gPM+), in improving mental health, child development, and related outcomes among rural Ethiopian households. gPM+ was delivered in separate arms by government-employed Health Extension Workers (HEWs) or stipended Local Facilitators (LFs) engaged by an NGO. Participants were drawn from the Productive Safety Net Program (PSNP) in Tigray, targeting individuals aged 18–64 years who showed signs of moderate to moderately severe depression. Villages across four districts were randomized into three arms: control, gPM+ delivered by HEWs, and gPM+ delivered by LFs. The study will be evaluated through a baseline, one-month and 12 month follow-up surveys. The data included here is from the screening and baseline surveys. The screening survey was conducted on 16,872 households to identify eligible individuals for the study, immediately followed by a baseline survey on the 3,744 households with an eligible respondent. The baseline survey collects information on household and individual characteristics including mental health, economic activities, and social behaviors. The data is organized by survey modules, screening modules include modules SA and SB, baseline modules include modules A-K. Module Z is last module on interview status filled out for all households that were screened.
