Abstract Plant-based animal product alternatives are increasingly promoted to achieve more sustainable diets. Here, we use a global economic land use model to assess the food system-wide impacts of a global dietary shift towards these alternatives. We find a substantial reduction in the global environmental impacts by 2050 if globally 50% of the main animal products (pork, chicken, beef and milk) are substituted—net reduction of forest and natural land is almost fully halted and agriculture and land use GHG emissions decline by 31% in 2050 compared to 2020.

Biofortified beans are being promoted in Burundi to solve malnutrition issues among rural households. The study was conducted in Muyinga and Gasorwe communes, where biofortified bean varieties were disseminated. This study aims to understand gender roles and practices in households and farms and how these roles and practices influence participation and uptake of biofortified beans. Lastly, it looks at the role of extension in increasing the uptake of agricultural technologies like biofortified bean varieties.

“Groundwater is the hidden water resource,” says Dr Andrew Ross, an honorary research fellow at the Australian National University’s Fenner School of Environment and Society. “It accounts for more than 99 percent of liquid freshwater on Earth, half of all drinking water and a quarter of the water used for irrigation, serving 38 percent of the world’s irrigated land.”

In Solomon Islands, many fishers, fish vendors and processors live and work in remote locations without
access to electricity, roads, clean water or landing-site facilities. Some may also lack the skills, knowledge or
capital to invest in new equipment or put their ideas into practice. As a result, fish is often handled in ways
that cause spoilage or contamination with dirt or bacteria, which can reduce income earned and make
consumers sick or hesitant to eat fish.

Rice production in sub-Saharan Africa (SSA) has increaed ten-fold since 1961, whereas its consumption has exceeded the production and the regional self-sufficiency rate is only 48% in 2020. Increase in rice production has come mainly from increased harvested area. Yield increase has been limited and the current average yield in SSA is around 2 t ha−1.

The link between climate change and conflict has been widely studied in the past decade. Despite empirical evidence leading to ambiguous, sometimes contradictory, conclusions, it is generally accepted that climate-related security risks are manifested through a non-linear and complex interplay between climate threats, sources of vulnerability, and drivers of conflict. The effects of this “vicious circle” are underlined by socioeconomic and political factors acting as drivers of insecurity.

The inventory of CSA approaches, practices, and technologies was compiled as an output of the CSA Writeshop that CCARDESA convened in October 2022 under the auspices of the AICCRA and GCCA+ projects with the primary objective of developing the CSA Handbook as well as a training manual for use in SADC region. The CSA Handbook has provided an elaboration of best-bet CSA options that have been categorized along the three pillars of CSA: increased productivity, adaptation, and mitigation.

The concept of regenerative agriculture has rapidly gained momentum among agri-food companies, governments, NGO’s and farmers. Although there is no widely accepted definition, different interpretations of this concept emphasize the importance of restoring and enhancing soil to generate multiple benefits for society and for farmers. The premise is that regenerative agriculture, by strengthening soil health and associated ecosystem services, helps to make agroecosystems more productive and resilient, while improving farmers’ livelihoods.

The impacts of climate change in Eastern and Southern Africa (ESA), are already well known to farmers. Over 2 million people in Kenya face threat of food insecurity due to climate change. Maize production is particularly vulnerable to climate change. It is projected to face not only 15% climate-related declines in yield without adaptation but also challenges from diminished cropland suitability and poor agronomic inputs and management; degraded environmental bases with declining soil fertility and degraded water systems are already apparent.
