A social analysis of the Red de Protección Social (RPS) in Nicaragua por Adato, Michelle, Roopnaraine, Terry, Álvarez, Fabiola Alvarado, Peña, Leticia Böttel, Castrillo, Gladys Meléndez

“…What is so important about CCTs is that first, they take a systematic approach to assuring a basic income safety net for the poor, rather than relying on more diffuse, indirect process of poverty reduction, e.g. through demand-driven infrastructure programs; and second, they aim to do more than just put short-term cash in people‘s hands—important as this aspect of safety nets is—but also to invest in the long-term human capital of future generations. …”

Disease and antimicrobial resistance surveillance for Nile tilapia pathogens in Lake Victoria, Kenya por Teplitz, E.M., Mwainge, V.M., Wacira, T.N., Ogwai, C., Mayianda, M.J., Ochieng, Linnet, Patel, Ekta, Getchell, R.G., Aura, C.M., Fiorella, K.J.

“…To gain a more comprehensive understanding of fish health in Lake Victoria, our study applied: (1) survey of cage farmer accounts, perceptions and responses to fish kill events; (2) rapid-response investigation to a significant tilapia mortality event; (3) active disease surveillance; and (4) antimicrobial resistance (AMR) testing of bacterial pathogens via disk diffusion. There were 82 fish kills recalled from 2020 to 2023 with total mortalities exceeding 1.8 million tilapia; yet, only 39% of farmers reported to Kenyan institutions and 17% of farmers attempted medical treatment. …”

Effect of eight tillage treatment on a tropical Alfisol: Maize growth and yield por Lal, R.

“…The 1500 h soil temperature on the ridged seedbed (H) at 5 cm depth exceeded 40°C, and was about 10°C more than in no-till with mulch (A). The oxygen diffusion rate (ODR) at 10 cm depth was the most in the no-till mulch and the least in the furrow bottoms. …”

Signaling, screening, or sunk costs? Experimental evidence on how prices affect agricultural technology adoption in East Africa por Van Campenhout, Bjorn, Abate, Gashaw T., Colen, Liesbeth, Kramer, Berber

“…Free samples are a widely used strategy to introduce new products or technologies, offering prospective users the opportunity to gain firsthand experience and potentially facilitate diffusion through social networks. However, concerns remain that giving away products for free may reduce their perceived value, increasing the risk that recipients will underutilize, repurpose, or resell the product rather than use it for its intended purpose. …”

Adoption impact and heterogeneity of mobile agricultural advisory technologies among smallholder farmers in Nigeria por Abioye, O., Fadare, D.A., Omitoyin, S.A., Ogunniyi, A.I., Olinya, P., Shaibu, A., Nwilene, F.E., Akande, A.

“…Gender-disaggregated analysis reveals nuanced heterogeneity: while men exhibit slightly higher baseline adoption probabilities, the effects of education and training substantially narrow the gender gap, suggesting that capacity-building interventions can promote gender-inclusive technology diffusion. To validate robustness, a Rosenbaum bounds sensitivity test confirms that the positive yield effects remain stable against potential endogeneity from unobserved factors. …”
