LysipheN: a gravimetric IoT device for near real-time high-frequency crop phenotyping: a case study on common beans
https://hdl.handle.net/10568/170092
Abstract
Climate instability directly affects agro-environments. Water scarcity, high air temperature, and changes in soil biota are some factors caused by environmental changes. Verified and precise phenotypic traits are required for assessing the impact of various stress factors on crop performance while keeping phenotyping costs at a reasonable level. Experiments which use a…

Digital artifacts reveal development and diffusion of climate research
https://hdl.handle.net/10568/131267
Abstract
Research for development organizations generate tremendous amount of accessible knowledge, but given their scale, time and resource constraints, the impact of outputs is not systematically analyzed. This is because traditional bibliometric analyses present limitations to synthesize accumulated knowledge and retrofitting indicators to historical outputs. To address these shortcomings, this study proposes an integrated,…

Cost-benefit analysis of prioritized climate adaptation strategies among smallholder farmers: Evidence from selected value chains across sub-Saharan Africa
https://hdl.handle.net/10568/119575
Abstract
Prioritization of adaptation options is complex. This study presents a multi-dimensional framework to evaluate how to allocate resources among competing alternatives. The main objectives of the study were to identify the prioritized climate-smart agricultural practices adopted among smallholder farmers in different value chains across…

Potential use of ash and lye to sterilize farm tools contaminated with Xanthomonas vasicola pv. musacearum
https://hdl.handle.net/10568/182093
Abstract
Tool sterilization is a critical component of managing Xanthomonas wilt of banana, because it disrupts a key transmission pathway of the causal agent Xanthomonas vasicola pv. musacearum ( Xvm ). Despite the availability of several sterilization options, uptake by smallholder farmers remains limited due to high costs, low accessibility, and practical constraints under field conditions…

National breeding programs and variety release processes: A systematic review of how the interactions shape diversity and adoption of dryland legumes and cereals in Africa
https://hdl.handle.net/10568/173832
Abstract
Dryland legumes and cereals are a good food source in Africa's drylands. However, their production is constrained by the limited availability of improved varieties and sustainable seed supply channels. The efficiency of breeding institutions and variety registration and release processes influence crop development…

Mate-choice for close kin is associated with improved offspring survival in Lodoicea maldivica, the largest-seeded plant in the world
https://hdl.handle.net/10568/138459
Abstract
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…

Biological control of the native endophytic fungus Pochonia chlamydosporia from the root nodule of Dolichos lablab on Fusarium wilt of banana TR4
https://hdl.handle.net/10568/173514
Abstract
Fusarium wilt of banana caused by Fusarium oxysporum f. sp. cubense , Tropical Race 4 (TR4) is a soil-borne disease, and it is devastating. At present, the biological control using antagonistic microorganisms to mitigate TR4 is one of the best strategies as a safe and green way. Yunnan has abundant and diverse microbial resources. Using the dual-…

Deconstructing leisure time and workload: case of women bean producers in Kenya
Bioversity-CIAT Alliance (Bioversity-CIAT Alliance)
https://hdl.handle.net/10568/113855
Abstract
Background: The notion of leisure became pronounced more than 20 years ago when women who worked on or out of the farm came home to a “second shift,” which entailed domestic work and childcare. This gap continues today not only between men and women but also among women and men. Women’s challenges in terms of their leisure arise out of or…

Abstract
Improving farming systems in resource-poor contexts is often difficult as farmers face multiple challenges to implement the innovations developed by researchers. Viable solutions may however be present within local communities by positive deviant farmers, i.e. farmers that outperform positively compared to others. This…

Gut-expressed vitellogenin facilitates the movement of a plant virus across the midgut wall in its insect vector
https://hdl.handle.net/10568/113983
Abstract
Many viral pathogens of global importance to plant and animal health are persistently transmitted by insect vectors. Midgut of insects forms the first major barrier that these viruses encounter during their entry into the vectors. However, the vector ligand(s) involved in the movement of plant viruses across the midgut barrier remains largely uncharacterized. Begomoviruses, many…

Abstract
Brachiaria humidicola (BH) (syn. Urochloa humidicola ) is an important forage grass in the tropics due to its capacity to grow in nutrient‐deficient soils, tolerate waterlogging, and inhibit soil nitrification. A major objective of BH breeding is to improve its nutritional quality. Therefore,…

Abstract
We study the effect of temperature on students' performance and how changes in the incentives to study alter this impact in the context of high-school exit exams in Colombia. We show that temperature increases have a negative impact on exam scores, particularly among urban students. Conversely, rural students exhibit slightly positive effects. Leveraging time-use data, we find evidence of individuals in rural…
