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

декабря, 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

декабря, 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.

Genetic identity, epidemiology and management of faba bean (Vicia Faba L.) gall disease in Ethiopia

декабря, 2021
Ethiopia

Ethiopia is the world’s second largest producer of faba bean (Vicia faba L.), and the crop has largest share of area and production of all pulses grown in Ethiopia. Faba bean is valued for its source of protein, income, and animal feedstock, and an important rotational crop. However, its current productivity is very low due to an emerging faba bean gall (FBG) disease and other biotic constraints. Initially, FBG disease-causing pathogen remained unconfirmed, but it was assumed to be caused by Olpidium sp.

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

декабря, 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).

Digital sequence information is changing the way genetic resources are used in agricultural research and development: implications for new benefit-sharing norms

декабря, 2021
Bermuda

This paper analyses the ways in which CGIAR Centers use digital sequence information (DSI) in their efforts to conserve and sustainably utilize the world’s most important crop and livestock genetic diversity.

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

декабря, 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.

Polycentrism: A case study on water access and management in community-based water tenure in Makopa and Simukale villages

декабря, 2021
Global

The objective of this study is to map community solutions to deal with climate variability and how information is mobilized into or interfaces with the next layer of government interventions that brings new perspectives in understanding how local solutions can be better mobilized into external solutions to climate change adaptation through horizontal and vertical integration processes, with a focus on living community-based water tenure in rural Zambia.

Just transitions for a Climate-Resilient Development in Africa – Transforming Dialogue into Action

декабря, 2021
Global

CCDA-X1, hosted by the Government of Namibia, convened on the theme: “Just transitions for a Climate-Resilient Development in Africa – Transforming Dialogue into Action” in collaboration with Africa’s civil society organisations, academia, development partners, regional and international organisations and the private sector.
The conference resulted in the following key messages to be taken forward to COP27 by Namibia.

The government of Ucayali, Peru, adopts deforestation-free, low- emissions strategies to strengthen cocoa and palm oil value chains

декабря, 2021
Peru

The strategies developed to promote deforestation-free, low- emission cocoa and oil palm value chains have been officially adopted by the regional government of Ucayali to guide public and private stakeholders towards improved sectorial and agricultural development. Both documents have been developed by the Alliance of Bioversity and CIAT in the framework of a project on “Business models to address drivers of deforestation in Peru” or Sustainable Amazon Businesses (SAB).

Policy Workshop on Co-learning Opportunity for the Water, Energy, Food and Ecosystems (WEFE) Nexus in Nepal

декабря, 2021
Nepal

Within Nepal, water, energy, food, and ecosystems (WEFE) are vital resources not merely for the current generation, but also for future ones, especially to satisfy the demands of a growing population and to respond to socio-economic changes. The WEFE nexus approach realizes that the management of water, energy, food, and ecosystems must be undertaken in a holistic way. Nevertheless, governments, investors, and other stakeholders face challenges in the management of WEFE resources, particularly in the face of climate change.
