Men can cook: Effectiveness of a men’s engagement intervention to change attitudes and behaviors in rural Ethiopia

Graduation model interventions seek to address multiple barriers constraining households’ exit from poverty, however, few explicitly target restrictive gender norms. Using a randomized controlled trial design, combined with three rounds of data, we investigate the impacts on gender equitable attitudes and behaviors of a graduation program that seeks to address multiple constraints for those in poverty and improve restrictive gender norms in Ethiopia. We find that at 1-year follow-up all treatment arms lead to improvements in men’s gender equitable attitudes and their engagement in household domestic tasks as reported by both men and women; but at 3-year follow-up, impacts are only sustained in the treatment arms that introduced men’s engagement groups after the 1-year follow-up survey to further promote improvements in equitable gender norms.

PSNP and sustainable land management in Ethiopia: A formative qualitative investigation

PSNP and sustainable land management in Ethiopia: A formative qualitative investigation

The Productive Safety Net Program (PSNP) is Ethiopia’s national safety net program, launched in 2005 and currently in its fifth phase. The objective of the PSNP is to protect households’ food consumption and assets, reduce their vulnerability to shocks, and address underlying causes of extreme poverty (MoA FSCD 2020). Households who have an adult available to work are required to take part in public works that focus on building infrastructure and improving the natural resource base (MoA FSCD 2020). As such, these projects are partially designed to contribute to disaster risk reduction and climate change adaptation and mitigation. However, there is limited evidence about how sustainable land management (SLM) activities are conducted under the PSNP on both publicly and privately operated lands, and how the uptake of these activities and their benefits differ by gender.

The effectiveness of cash and cash plus interventions on livelihoods outcomes: Evidence from a systematic review and meta-analysis

The effectiveness of cash and cash plus interventions on livelihoods outcomes: Evidence from a systematic review and meta-analysis

Cash transfer programs have become increasingly popular tools for fighting chronic poverty and food insecurity in lowand middle-income countries (Fiszbein and Schady, 2009; USAID, 2022; WFP, 2023). Cash transfers offer recipients flexibility by permitting them to finance immediate consumption needs or to increase future income streams through investments and savings. Moreover, these programs are generally feasible to implement and scale across diverse contexts. While studies consistently show cash transfers effectively reduce poverty in the short term, the evidence on their long-term impact is less clear.
