Data-driven decentralized breeding increases prediction accuracy in a challenging crop production environment
https://hdl.handle.net/10568/114893
Abstract
Crop breeding must embrace the broad diversity of smallholder agricultural systems to ensure food security to the hundreds of millions of people living in challenging production environments. This need can be addressed by combining genomics, farmers’ knowledge, and environmental analysis into a data-driven decentralized approach (3D-breeding). We tested this idea as a proof-of-…

Separate and joint interests: Understanding gendered innovation processes in Ugandan farm systems
https://hdl.handle.net/10568/116297
Abstract
Agricultural innovation is considered paramount in solving poverty, food insecurity and malnutrition in the global south and notably in the East-African highlands. However, processes of change surrounding innovation in agriculture, and potential gender differences in their impacts, are often poorly understood. This paper resorts to principles from Farming Systems Research (FSR) and social…

Quantifying residual soil moisture through empirical orthogonal functions analysis to support legume-based cropping systems
https://hdl.handle.net/10568/159313
Abstract
This study investigates spatiotemporal variability of residual soil moisture during the OND (October-November-December) season in Ethiopia and its implications for crop productivity. Employing advanced statistical techniques, we analyze spatial and temporal distribution of soil moisture across Ethiopia from 1981 to 2020, focusing on selected crops including legumes:…

AcEXPA1, an α-expansin gene, participates in the aluminum tolerance of carpetgrass (Axonopus compressus) through root growth regulation
https://hdl.handle.net/10568/173773
Abstract
Aluminum (Al) toxicity is a major mineral toxicity that limits plant productivity in acidic soils by inhibiting root growth. Carpetgrass (Axonopus compressus), a dominant warm-season turfgrass widely grown in acidic tropical soils, exhibits superior adaptability to Al toxicity. However, the mechanisms underlying its Al tolerance are largely unclear, and…

Indigenous communities' perceptions reveal threats and management options of wild edible plants in semiarid lands of northwestern Kenya
https://hdl.handle.net/10568/130625
Abstract
Background: Understanding how local communities perceive threats and management options of wild edible plants (WEPs) is essential in developing their conservation strategies and action plans. Due to their multiple use values, including nutrition, medicinal, construction, and cultural as well as biotic and abiotic pressures, WEPs are exposed to…

Predicting the future climate-related prevalence and distribution of crop pests and diseases affecting major food crops in Zambia
https://hdl.handle.net/10568/126941
Abstract
Environmental factors determine the suitability of natural habitats for crop pests and often facilitate their proliferation and that of the crop diseases they carry. Crop pests and diseases damage food crops, significantly reducing yields for these commodities and threatening food security in developing, predominantly agricultural economies. Given its impact on…

Breaking down silos: Conservation areas for Amazonian flagship terrestrial and freshwater species
https://hdl.handle.net/10568/176187
Abstract
Research into the threats affecting flagship terrestrial and freshwater species in the Amazon has operated within disciplinary and ecological silos, neglecting the interconnectedness between these species and ecosystems. In this study, we aimed to bridge these divides by identifying Amazon areas harboring high jaguar densities and high richness of migratory freshwater species, highlighting the…

Genetic differentiation in Khaya Ivorensis A. Chev., a threaten tree of evergreen African rainforests
https://hdl.handle.net/10568/158278
Abstract
Phylogeographic studies on widespread rainforest species from West and Central Africa often reveal genetic discontinuities. These discontinuities can originate from past barriers to gene flow resulting from long-lasting population fragmentation during glacial periods, according to the forest refuge hypothesis. This study 69 nuclear SNPs, 13 plastid SNPs, and 24 mitochondrial SNPs to…

Abstract
This paper reviewed a body of literature on climate adaptation options in sub-Saharan Africa's (SSA) smallholding agriculture and complemented it with a case study involving experts interviews, focus group discussions, large-scale household surveys, and farmer practices observation while drawing insight…

Ten simple rules for switching from face-to-face to remote conference: An opportunity to estimate the reduction in GHG emissions
https://hdl.handle.net/10568/115908
Abstract
In the context of wolrd pandemics, many face-to-face conference are to be canceled in profit or virtual ones. This publication propose ten simple rules and many other recommandations in order to turn a face-to-face conference into a remote virtual one and take into account the GHG emission reduction.

MeWRKY IIas, subfamily genes of WRKY transcription factors from cassava, play an important role in disease resistance
https://hdl.handle.net/10568/127678
Abstract
Cassava (Manihot esculenta Crantz) is an important tropical crop for food, fodder, and energy. Cassava bacterial blight (CBB) caused by Xanthomonas axonopodis pv. manihotis (Xam) occurs in all cassava growing regions and threatens global cassava production. WRKY transcription factor family plays the essential roles during plant growth, development, and abiotic or biotic…

Improving efficiency of knowledge and technology diffusion using community seed banks and farmer-to-farmer extension: experiences from Malawi

Abstract
Background: Agri-innovations are mostly delivered to farmers through private and public sector-led institutions around the world, with various degrees of success in Malawi. These distribution systems, on the other hand, do not meet everyone’s production and productivity needs, particularly those of smallholder farmers. Alternative gap-flling systems…

Abstract
Many seafood products marketed as “sustainable” are not. More exacting sustainability standards are needed to respond to a fast-changing world and support United Nations SDGs. Future fisheries must operate on principles that minimise impacts on marine life, adapt to climate change and allow regeneration of depleted biodiversity, while supporting and enhancing the health, wellbeing and resilience of people and…

Abstract
Standard tools that can quantitatively track the impacts of higher global demand for animal-sourced food to their local environmental effects in developing countries are largely missing. This paper presents a novel integrated assessment framework that links a model of the global agricultural and food system, a landscape-level environmental impact assessment model, and an…
