    Maize is an important staple crop for the majority of the population in Uganda. However, in tropical and subtropical climates, maize is frequently contaminated with aflatoxins, a group of cancer-causing and immuno-suppressive mycotoxins produced by Aspergillus section Flavi fungi. In Uganda, there is limited knowledge about the causal agents of aflatoxin contamination. The current study determined both the aflatoxin levels in pre-harvest maize across Uganda and the structures of communities of aflatoxin-producing fungi associated with the maize.

    Management practices such as tillage, crop rotation, irrigation, organic and inorganic inputs application are known to influence diversity and function of soil microbial populations. In this study, we investigated the effect of conventional versus organic farming systems at low and high input levels on structure and diversity of prokaryotic microbial communities. Soil samples were collected from the ongoing long-term farming system comparison trials established in 2007 at Chuka and Thika in Kenya. Physicochemical parameters for each sample were analyzed.

    Cocoa agroforestry systems differ in the diversity of shade tree species composition. Though cocoa benefits from shade, there is a lack of species-specific information on shade trees that enhance soil fertility and yield.
    We examined how soil characteristics and cocoa yield were affected by eight commonly retained forest tree species, compared with unshaded control plots over a 3-year period.

    The manual is designed to assist the reader with information about soybean value chain and its management in times of climate change. It is comprised of six chapters of coordinated content as summarized below. First chapter of this manual is focused on the soybean and its development and also describes the status of soybean in Uganda and its significance.

    Fonio (Digitaria exilis(Kippist)Stapf) and Bambara groundnut (Vigna subterranea(L.)Verdc.) are native crops grown at a small scale in Mali that have potential to support agricultural productivity under climate change. A community biodiversity management approach was explored in this study as a means to reinforce the cultivation of these crops by increasing farmers’ access to intraspecific diversity and developing capacities of community institutions for their management. The research involved six communities in Ségou and Sikasso regions.

    Cassava-maize intercropping is a common practice among smallholder farmers in Southern Nigeria. It provides food security and early access to income from the maize component. However, yields of both crops are commonly low in farmers’ fields. Multi-locational trials were conducted in Southern Nigeria in 2016 and 2017 to investigate options to increase productivity and profitability through increased cassava and maize plant densities and fertilizer application.

    Micro Small and Medium-Enterprises (MSMEs) in many developing countries play an important role in the agri-food systems. They provide employment opportunities as well as source of foods for urban consumers. In Kenya, the MSMEs provide an interesting disruption in the rapidly growing traditional markets. Efficient sourcing of foodstuffs is one of the challenges faced by MSME food vendors in Nairobi. Traditionally small-scale food vendors travel by informal buses to wholesale wet markets several times a week to source limited volumes of fresh fruit and vegetables.

    Diet quality is a critical determinant of human health and increasingly serves as a key indicator for food system sustainability. However, data on diets are limited, scattered, often project-dependent, and current data collection systems do not support high-frequency or consistent data flows. We piloted in Rwanda a data collection system, powered by the principles of citizen science, to acquire high frequency data on diets. The system was deployed through an unstructured supplementary service data platform, where respondents were invited to answer questions regarding their dietary intake.

    Across a wide range of inequality measures, survey data measure lower levels of inequality in 2019/20 compared to a decade earlier in 2010/11. The latest survey data put Malawi’s Gini Coefficient at 0.38. The 20% richest households consume about half of the country’s total consumption. The poorest 20% account for only 6% of total consumption. Differences between districts or regions are not the primary contributors to inequality. Differences across households within the same region or district contribute much more to total inequality.

    Smallholder production systems in low-income countries suffer the most from the impacts of climate change but receive the least benefit from climate adaptation programs. This is due to governance structures that make it difficult for governments and organizations to effectively reach marginalized communities. Technical, financial, and institutional support is provided in vertical siloes, limiting coordination between national government departments and hindering integrated climate interventions.
