    The adoption of sustainable agricultural mechanization (SAM) can sustainably increase productivity, and increase ecosystem resilience. Thirty (30) baby trials and One mother trial were established to expand access to smallholder farmers to SAM technologies and generate and share scientific evidence on the performance of SAM technologies, services and information in Ghana. The demonstration trials utilize participatory research and extension approaches by using existing partnerships.

    This study seeks to increase the efficiency of yam breeding practice using farmers’ insight at the trait and socioeconomic levels. A three-staged multisampling procedure was employed and 792 yam farmers from four geopolitical zones, comprising 10 states and the Federal Capital Territory, Abuja in Nigeria were randomly selected. Farmer’s preference criteria and factors pertinent to improving the efficiency of yam breeding in Nigeria were documented.

    The uptake of conservation agriculture and farm mechanization in Southern Africa has been slow and low. As a result, most smallholder farmers continue to grow crops under degraded soils using conventional tools and human powered farm operations. This leads to low productivity. Therefore, spatially visualizing areas where conservation agriculture and farm mechanization can be targeted can be crucial to guide targeting and scaling.

    Livestock are a critically important component of the food system, although the sector needs a profound transformation to ensure that it contributes to a rapid transition towards sustainable food systems. This chapter reviews and synthesises the evidence available on changes in demand for livestock products in the last few decades, and the multiple socio-economic roles that livestock have around the world. We also describe the nutrition, health, and environmental impacts for which the sector is responsible.

    This report presents the consolidated outputs of the CGIAR researchers involved in the first cohort of the CGIAR Food Systems Accelerator. The Food Systems Accelerator was established to bolster Ukama Ustawi, a CGIAR initiative focused on transforming agri-food systems in East and Southern Africa (ESA). This program, spanning from 2022 to 2024, aligned scientists with agribusinesses to bring CGIAR innovations to scale in ESA.

    The intensification of agricultural systems in sub-Saharan Africa (SSA) is necessary to reduce poverty and improve food security, but increased nutrient applications in smallholder systems could have negative consequences for water quality, greenhouse gas emissions, and air quality.

    Developing optimal strategies for nutrient management of soils and crops at a larger scale requires an understanding of nutrient limitations and imbalances. The availability of extensive data (n = 1,781) from 2-yr nutrient omission trials in the most suitable agroecological zone for maize (Zea mays L.) in Nigeria (i.e., the northern Guinea savanna) provides an opportunity to assess nutrient limitations and imbalances using the concept of multi-ratio compositional nutrient diagnosis (CND).

    The Amazon Basin features a vast network of healthy, free-flowing rivers, which provides habitat for the most biodiverse freshwater fauna of any basin globally. However, existing and future infrastructure developments, including dams, threaten its integrity by diminishing river connectivity, altering flows, or changing sediment regimes, which can impact freshwater species.
