Analysis of food system drivers of deforestation highlights foreign direct investments and urbanization as threats to tropical forests
https://hdl.handle.net/10568/149225
Abstract
Approximately 90% of global forest cover changes between 2000 and 2018 were attributable to agricultural expansion, making food production the leading direct driver of deforestation. While previous studies have focused on the interaction between human and environmental systems, limited research has explored deforestation from a food system perspective. This…

Isolation, genome analysis and tissue localization of ceratobasidium theobromae, a new encounter pathogen of cassava in Southeast Asia
https://hdl.handle.net/10568/152318
Abstract
In Southeast Asia (SEA) fastidious fungi of the Ceratobasidium genus are associated with proliferation of sprouts and vascular necrosis in cacao and cassava, crops that were introduced from the tropical Americas to this region. Here, we report the isolation and in vitro culture of a Ceratobasidium sp. isolated from cassava with symptoms of witches'…

Enhanced scab resistance in apple conferred by Rvi6 and polyploidy is linked with distinct shifts in the phenolics profile
https://hdl.handle.net/10568/175765
Abstract
Apple (Malus × domestica Borkh.) production is threatened by scab, caused by the fungus Venturia inaequalis. One defense mechanism of apple trees against fungal pathogens such as V. inaequalis is the biosynthesis of antifungal compounds. Amongst these, phenolic compounds are particularly hypothesized to correlate with scab resistance, thereby offering a putative route…

The potential impact of banana Xanthomonas wilt on food systems in Africa: modeling scenarios of policy response and disease control measures
https://hdl.handle.net/10568/131569
Abstract
Banana Xanthomonas wilt (BXW) is one of the most important diseases threatening banana production in Africa south of the Sahara (SSA). In this study, we examine the potential impacts of BXW on banana production, demand, and food security in SSA, if the disease spread across all banana-producing countries in the region. The analysis is based on a…

Validation of enteric methane emissions by cattle estimated from mathematical models using data from in vivo experiments
https://hdl.handle.net/10568/178436
Abstract
Several authors have developed equations to estimate methane (CH4) emissions by cattle according to variables such as dry matter and nutrient intake, live weight, or weight gain. Mathematical models using these variables show a large variability of results, being necessary to identify those which provide more precise and accurate predictions. For this reason, the…

The interactive effect of temperature and fertilizer types determines the dominant microbes in nitrous oxide emissions and the dicyandiamide efficacy in a vegetable soil
https://hdl.handle.net/10568/138610
Abstract
Heat waves associated with global warming and extreme climates would arouse serious consequences on nitrogen (N) cycle. However, the responses of the functional guilds to different temperatures, especially high temperature and the cascading effect on N2O emissions remain unclear. An incubation study was conducted to…

Why building participatory dashboards is key for sustainable food system transformation
https://hdl.handle.net/10568/149241
Abstract
In recent years, numerous examples of food system dashboards have been developed with the goal of offering users the opportunity to monitor or assess (their) national food systems. One of the many challenges faced by these initiatives has been to strike an acceptable balance between the complexity, local-specificity, and multi-sectoral nature of these food systems while also ensuring that the…

Near-infrared spectroscopy and wet chemistry dataset for forage nutritional quality assessment in Urochloa humidicola
https://hdl.handle.net/10568/174967
Abstract
Assessing the nutritional quality traits of pastures is crucial for germplasm and breeding evaluations, enabling the selection of high-quality forages to enhance livestock productivity. However, traditional laboratory analytical methods are logistically demanding and costly, particularly in large-scale trials, underscoring the need for rapid, precise, and high-throughput…

Mapping the climate and agronomic digital advisory services landscape in West and Central Africa: A step towards making food systems productive and climate resilient
https://hdl.handle.net/10568/178548
Abstract
This study explores and examines the availability of digital agricultural solutions (DAGs) to enhance agricultural resilience in the face of climate change. The countries under study—Burundi, Ivory coast, Democratic Republic of Congo (DRC), Ghana, Nigeria, and Rwanda—display varying levels of vulnerability, suffering from low…

Integrating science for simultaneously addressing loss and damage from climate change and strengthening social protection
https://hdl.handle.net/10568/177140
Abstract
Expanding social protection to at-risk communities in climate-vulnerable countries is proposed to become a core pillar of addressing loss and damage associated with climate change. Conceptual advances have been made but remain disconnected from realities: expanding the currently low coverage of social protection in climate-vulnerable countries will require significant…

Foodomics: A data-driven approach to revolutionize nutrition and sustainable diets
https://hdl.handle.net/10568/131527
Abstract
Globally, we are failing to meet numerous nutritional, health, and environmental targets linked to food. Defining food composition in its full chemical and quantitative diversity is central to data-driven decision making for supporting nutrition and sustainable diets. "Foodomics"-the application of omics-technology to characterize and quantify biomolecules to improve wellbeing-has the potential to…

Abstract
The Southern African Mission in Mozambique (SAMIM) has been relatively under-researched in view of its conception among Mozambicans. This study used views, insights and attitudes of Mozambicans in Johannesburg, South Africa on the relevance of the SAMIM‟s counterinsurgency efforts in Cabo Delgado. While the deployment of the SAMIM‟s…

Global hotspots of climate change adaptation and mitigation in agriculture
https://hdl.handle.net/10568/135022
Abstract
As countries prioritize climate action under the Paris Agreement, determining the overlap in agricultural areas requiring both adaptation and mitigation (A&M) interventions could lead to more efficient use of resources and support for farmers. Here, we identify global priorities for A&M by evaluating global datasets on greenhouse gas (GHG) emissions and climate hazards related to agriculture. We show that…
