“…Adoption of ISFM requires up-front investments of substantial labor; it also takes several years to realize its benefits (Jayne et al, 2019). For example, Schmidt, Chinowsky, Robinson, and Strzepek (2017) show that soil and water management investment must be maintained for at least 7 years to achieve significant increases in value of production. Therefore, resource-rich farmers are more willing to make such investments than resource-poor farmers who tend to prioritize their immediate needs for sustenance (Jayne et al, 2019).…”

Given the stagnant agricultural productivity and persistent food insecurity in low‐income countries—notably in sub‐Saharan Africa (SSA)—there has been continued interest in the adoption of new technology and its impact on productivity in these regions. To increase crop yields and sustain yield gains, recent case studies of technology adoption unanimously recommend the adoption of integrated farm management systems, particularly in SSA. On the other hand, there have been increasing numbers of studies on social network or farmer‐to‐farmer technology extension. These studies explore more efficient extension systems than traditional public‐sector extension approaches. This article reviews both recent case studies of technology adoption and its productivity impacts as well as studies on agricultural extension to identify common findings, shortcomings, and major remaining issues.

“…Several recent studies in Agricultural Economics have examined the determinants of adoption (and/or impacts on outcomes other than child nutrition) of some of these practices or other land management practices in SSA (e.g., Abdulai, ; Amare & Shiferaw, ; Manda, Alene, Gardebroek, Kassie, & Tembo, ; Schmidt, Chinowsky, Robinson, & Strzepek, ; Wainaina, Tongruksawattana, & Qaim, ; Wossen, Berger, & Di Falco, ).…”

Does sustainable intensification of maize production enhance child nutrition? Evidence from rural Tanzania

Food insecurity, child malnutrition, and land degradation remain persistent problems in sub-Saharan Africa. Agricultural sustainable intensification (SI) has been proposed as a possible solution to simultaneously address these challenges. Yet there is little empirical evidence on if agricultural management practices and inputs that contribute to SI from an environmental standpoint do indeed improve food security or child nutrition. We use three waves of data from the nationally-representative Tanzania National Panel Survey to analyze the child nutrition effects of rural households' adoption of farming practices that can contribute to the SI of maize production. We group households into four categories based on their use of three soil fertility management practices on their maize plots: "Nonadoption"; "Intensification" (use of inorganic fertilizer only); "Sustainable" (use of organic fertilizer, maize-legume intercropping, or both); and "SI" (joint use of inorganic fertilizer with organic fertilizer and/or maize-legume intercropping). The results from multinomial endogenous treatment effects models with the Mundlak-Chamberlain device suggest that use of practices in the "SI" category is associated with improvements in children's height-for-age and weight-for-age z-scores relative to "Nonadoption," particularly for children aged 25-59 months. These effects appear to come through improvements in both crop income and productivity.

“…incentives for modern input use and adoption of new technology. These investments and policies are particularly important because in many parts of the country land degradation is reducing yields, necessitating further investments in sustainable land management, as well as increased fertilizer use to enable even moderate yield gains (Schmidt et al 2017).…”

Climate change impacts on crop yields in Ethiopia

We present results of model simulations of maize, wheat, and sorghum yields in Ethiopia through 2085. The analysis draws on climate outcomes from 32 global climate models and an agronomic crop model to estimate effects on the yields of these cereals of expected higher temperatures and, for most of Ethiopia, increased rainfall. The simulation results suggest that climate change will likely have only relatively small effects on average yields of maize, wheat, and sorghum in Ethiopia up to 2055, as agronomic conditions for cultivation of these crops may actually improve in large parts of the country. Nonetheless, yields will need to increase over time to enable cereal production to keep pace with expected demand growth due to increases in population and per capita incomes. Moreover, even if future changes in climate have only moderate impacts on average crop yields in Ethiopia, there is growing evidence that weather outcomes are likely to become more variable in the future, implying that severe droughts and floods may very well have a greater impact on cereal production in the future than in the past.
