Abstract Rice hoja blanca (RHB) is one of the most serious diseases in rice-growing areas in tropical Americas. Its causal agent is RHB virus (RHBV), transmitted by the planthopper Tagosodes orizicolus Müir. Genetic resistance is the most effective and environment-friendly way of controlling the disease. So far, only 1 major quantitative trait locus (QTL) of Oryza sativa ssp. japonica origin, qHBV4.1, that alters the incidence of the virus symptoms in 2 Colombian cultivars has been reported.

This article pulls together the state of knowledge on the degree to which wheat-based systems in Bangladesh, India, Nepal, and Pakistan, are feminizing. It is not yet possible to make definitive statements. However, it is clear that wheat-based systems are undergoing far-reaching changes in relation to “who does what” and “who decides.” There are some commonalities across all four countries. Intersectionalities shape women’s identities and abilities to exert their agency. Purdah is a cultural norm in many locations. Nevertheless, each country displays different meta-trends.

Mixed farming systems (MFS) are the main food source and exist across almost all agroecological regions in the Global South. A systematic scoping review was conducted to identify the status of integrated crop-livestock research in MFS of the Global South. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol was used to identify 210 studies (excluding reviews) addressing productivity, resilience, challenges, opportunities, and perceptions of integrating crops and livestock in the Global South from the Scopus and Web of Science database.

Although Ghana is a leading global cocoa producer, its production and yield have experienced declines in recent years due to various factors, including long-term climate change such as increasing temperatures and changing rainfall patterns, as well as drought events. With the increasing exposure of cocoa-producing regions to extreme weather events, the vulnerability of cocoa production is also expected to rise. Supplemental irrigation for cocoa farmers has emerged as a viable adaptation strategy to ensure a consistent water supply and enhance yield.

Agroforestry-based food systems play a critical role in many dryland regions of the word, including Tunisia. These farming systems offer a range of benefits such as diversification of food and income resources for local communities, biodiversity conservation, and environmental resilience. Fig trees, olives, carob, and honey are common features of these Mediterranean agroforestry landscapes, and their produce is a traditional staple in many cuisines.

Livestock food systems largely contribute to the overall food systems’ greenhouse gas (GHG) emissions and are thus put at the centre of global policy and research agendas on mitigation and adaptation. An additional growing concern on the prevalence of globalised animal product value chains and the specialisation of agricultural markets and their environmental pressures over supply networks further adds to this debate.

Amidst global efforts to combat deforestation, achieve net-zero carbon goals, and comply with rigorous certification standards, agro-industries are facing mounting pressure to substantiate their commitment to sustainable practices. The European Union Deforestation-Free Regulation (EUDR) introduces an extra layer of scrutiny, compelling the adoption of a strategic approach to address environmental concerns.

Agriculture has played a crucial role in supporting smallholder livelihoods in Bangladesh. Despite being actively involved in various stages of production, including seed sowing, harvesting, and postharvesting, women's contributions are often undervalued. They are often regarded as a cheap labor force and are not given meaningful roles in the supply and value chains. One of the primary challenges they face is the lack of access to and ownership of land, which results in limited and unequal access to resources such as credit, services, markets, and information on modern technologies.

We studied spatial patterns of kinship in the offspring of the endangered Lodoicea maldivica, a dioecious palm that produces the largest seed of any plant. Previous research has suggested that restricted seed and pollen dispersal in populations resulted in strong spatial genetic structure. We used microsatellites to genotype young plants and their potential parents at four sites across the species’ entire natural range.
