Scaling readiness: learnings from applying a novel approach to support scaling of food system innovations

Dezembro, 2021
Global

Scaling of innovations is a key requirement for addressing societal challenges in sectors such as agriculture, but research for development programs struggles to make innovations go to scale. There is a gap between new complexity-aware scientific theories and perspectives on innovation and practical approaches that can improve strategic and operational decision-making in research for development

Capacities and needs assessment of gender research in CGIAR

Dezembro, 2021
Kenya

"In November 2020, CGIAR commissioned Michigan State University’s Center for Gender in Global Context (GenCen) to conduct a capacities and needs assessment (CNA) to determine, with the participation of stakeholders throughout CGIAR and (to a lesser extent) the broader agricultural research for development (AR4D) network, how the GENDER Platform could best strengthen the capacities needed to achieve the Platform’s desired outcomes. Four overarching questions guided the CNA:
• What is quality gender research?

Food composition table of selected local tree species in Burkina Faso. Version 1

Dezembro, 2021
Burkina Faso

Food composition tables (FCT) inform on the nutritional composition of foods consumed and are an essential resource for understanding and analyzing dietary intake data related to both individuals and communities, and for developing healthy recipes and food products. They are a fundamental piece of knowledge to support interventions related to improving nutrition, health, and food security in all contexts.

Estimation of soybean grain yield from multispectral high-resolution UAV data with machine learning models in west Africa

Dezembro, 2021
Global

Soybean (Glycine max (L.) Merr.) is a leguminous and oil crop with rapidly growing importance and demand in Africa following the increasing demand for oil and livestock and poultry feed in sub-Saharan Africa. However, soybean productivity is low in most countries of sub-Saharan Africa, especially in West Africa, where productivity is below one ton per ha. Hence, concerted soybean varietal development and testing efforts have been underway by the International Institute of Tropical Agriculture (IITA), collaborating with the various African and US-based soybean breeding programs.

Digital extension, price risk, and farm performance: experimental evidence from Nigeria

Dezembro, 2021
Nigeria

Despite decades of investment in agricultural extension, technology adoption among farmers and agricultural productivity growth in Sub-Saharan Africa remain slow. Among other shortcomings, extension systems often make recommendations that do not account for price risk or spatial heterogeneity in farmers' growing conditions. However, little is known about the effectiveness of extension approaches for nutrient management that consider these issues.

Report of the global online survey to identify key knowledge and capacity gaps on diagnostics and surveillance of pests & diseases in targeted countries

Dezembro, 2021
Global

An online survey was co-designed in collaboration with CGIAR Germplasm Health Units (GHUs) leaders and social scientists of the Plant Health Initiative (PHI), with the objective to identify and map the key knowledge and capacity gaps on lab/field detection, characterization, and surveillance of P&D of local and regional NPPOs in targeted countries. The questionnaire consisted of 43 open-ended, single and multiple-choice questions.

Receptor-like Kinases (LRR-RLKs) in response of plants to biotic and abiotic stresses

Dezembro, 2021
Global

Plants live under different biotic and abiotic stress conditions, and, to cope with the adversity and severity, plants have well-developed resistance mechanisms. The mechanism starts with perception of the stimuli followed by molecular, biochemical, and physiological adaptive measures. The family of LRR-RLKs (leucine-rich repeat receptor-like kinases) is one such group that perceives biotic and abiotic stimuli and also plays important roles in different biological processes of development.

Tephritid fruit fly species composition, seasonality, and fruit infestations in two central African agro-ecological zones

Dezembro, 2021
Global

Bactrocera dorsalis and several Africa-native Ceratitis species are serious constraints to fruit
production in sub-Saharan Africa. A long-term trapping and fruit collection study was conducted
(2011–2016) in two contrasting agro-ecological zones (AEZs) of Cameroon to determine fruit fly
species composition, seasonality, attraction to various lures and baits, and fruit infestation levels.
Ten tephritid species from genera Bactrocera, Ceratitis, Dacus, and Perilampsis were captured in traps.

Adaptability and Stability of Faba Bean (Vicia faba L.) Accessions under Diverse Environments and Herbicide Treatments

Dezembro, 2021
Global

The adaptability and stability of 37 faba bean (Vicia faba L.) accessions with different levels of tolerance to metribuzin or imazethapyr was assessed across 12 season–location–herbicide experiments. Significant Genotype x environment (GE) interaction was found for the days to flowering (DFLR), plant height (PLHT) and grain yield (GY). Performance and stability of the accessions regarding PLHT and GY were assessed using four different stability parameters: cultivar superiority, static stability, Wricke’s eco-valence and Finlay and Wilkinson’s regression model.

Identification of genomic regions associated with agronomic and disease resistance traits in a large set of multiple DH populations

Dezembro, 2021
Global

Breeding maize lines with the improved level of desired agronomic traits under optimum and drought conditions as well as increased levels of resistance to several diseases such as maize lethal necrosis (MLN) is one of the most sustainable approaches for the sub-Saharan African region. In this study, 879 doubled haploid (DH) lines derived from 26 biparental populations were evaluated under artificial inoculation of MLN, as well as under well-watered (WW) and water-stressed (WS) conditions for grain yield and other agronomic traits.

Phenotypic and Genetic Characterization and Design of Community-Based Breeding Programs for Two Indigenous Goat Populations of Ethiopia

Dezembro, 2021
Ethiopia

The aim of the dissertation was to undertake phenotypic and genetic characterization and design community-based breeding programs for two indigenous goat populations in Ethiopia, namely Arab and Oromo. The dissertation was based on five manuscripts. Papers I, II, IV and V were based on data generated from production system, morphological characterization and ranking experiments. Paper III was based on whole genome data generated from three indigenous goat populations (Arab, Fellata and Oromo).

High-Temperature and Drought Stress Effects on Growth, Yield and Nutritional Quality with Transpiration Response to Vapor Pressure Deficit in Lentil

Dezembro, 2021
Global

High temperature and water deficit are among the major limitations reducing lentil (Lens culinaris Medik.) yield in many growing regions. In addition, increasing atmospheric vapor pressure deficit (VPD) due to global warming causes a severe challenge by influencing the water balance of the plants, thus also affecting growth and yield.
