Reconciling yield gains in agronomic trials with returns under African smallholder conditions

Décembre, 2019
Global

Increased adoption of improved agricultural technologies is considered an essential step to address global poverty and hunger, and agronomic trials suggest intensification in developing countries could result in large yield gains. Yet the promise of new technologies does not always carry over from trials to real-life conditions, and diffusion of many technologies remains limited.

Assessing the ability of Sentinel-2 derived vegetation indices to explain inter-field yield variation in the context of index insurance - A case study of paddy rice inHaryana and Odisha, India

Décembre, 2019
India

Smallholder agriculture in the Global South is characterised by high degree of risk, which disincentivises investment in productivity gains and limits rural development. Index Insurance aims to overcome the limitations of traditional insurance to insurance farmers against exposure to climatic extremes. Based on two study sites in India, Haryana and Odisha, this study

Urochloa grasses swap nitrogen source when grown in association with legumes in tropical pastures

Décembre, 2019
Global

The degradation of tropical pastures sown with introduced grasses (e.g., Urochloa spp.) has
dramatic environmental and economic consequences in Latin America. Nitrogen (N) limitation to
plant growth contributes to pasture degradation. The introduction of legumes in association with
grasses has been proposed as a strategy to improve N supply via symbiotic N2 fixation, but the fixed
N input and N benefits for associated grasses have hardly been determined in farmers’ pastures.

Value chain analysis of Chaya (Mayan Spinach) in Guatemala

Décembre, 2019
Guatemala

Chaya is a highly nutritious perennial leafy vegetable native to Mesoamerica. This drought-resistant crop has low production and consumption levels in Guatemala, but has the potential to help agriculture and food systems be more nutritious and resilient. This study analyzed the value chain of chaya in Guatemala, and identified bottlenecks and opportunities for its use-enhancement. This research, the first of its kind applied to this crop in Guatemala, combined Rapid Market Appraisal tools.

Evaluation of feed resources for local goat production under traditional management systems in Golomoti EPA Dedza and on-station at Bunda Campus, LUANAR, Malawi

Décembre, 2019
Malawi

The on-station study was conducted at Sakhula, Bunda College (LUANAR), and on-farm in Golomoti Extension Planning Area (EPA). The objectives of the study were to assess constraints to goat production, to assess pre-weaning body weights of local Malawi goat kids, to analyze the nutrient content of selected tree and grass fodder species and to evaluate effect of feeding goats with Faidherbia albida pods and Gliricidia sepium based supplements on feed intake, growth rate and carcass quality.

Distribution, prevalence, and severity of damages caused by nematodes on yam (Dioscorea Rotundata) in Nigeria

Décembre, 2019
Nigeria

Nigeria is the main yam-growing country of the world. In the country, various plant-parasitic nematodes have been reported constraining yam production and the storability of tubers. This study established the damage level of nematodes on white yam tubers (Dioscorea rotundata) across the major production areas in the country for management purposes.

CRP 2020 Reviews: Roots, Tubers and Bananas

Décembre, 2019
Global

In 2020 the CGIAR CAS Secretariat is conducting independent reviews of the 12 CGIAR Research Programs (CRPs), including this one of RTB. The reviews will provide information on quality of science and effectiveness in each CRP. This review covers the Phase II years of 2017 through 2019, with a view to identifying lessons for future research modalities.

Vietnam reduced additional 1.5MtCO2-eq/year through outscaling low-emission technologies in rice production with IRRI-CCAFS' contributions and increases Agriculture-Nationally Determined Contributions mitigation target by 16MtCO2-eq by 2030.

Décembre, 2019
Global

In its updated Nationally Determined Contributions, Vietnam raised the Agriculture-greenhouse gas mitigation target by 16MtCO2-eq; 100% of Ag-unconditional target will come from rice. With IRRI-CCAFS contributions, climate-smart rice production was introduced to 17,000 extension staff and 75,800 farmers within Vietnam's extension programs; while the Vietnam-Sustainable Agriculture Transformation project almost doubled the low-emission technology adoption area, reaching 163,418ha. Alternate Wetting and Drying and rice straw removal are outscaled in An Giang province.

Exploring black soldier fly frass as novel fertilizer for improved growth, yield, and nitrogen use efficiency of maize under field conditions

Décembre, 2019
Tanzania

Black soldier fly frass fertilizer (BSFFF) is increasingly gaining momentum worldwide as organic fertilizer. However, research on its performance on crop production remains largely unknown. Here, we evaluate the comparative performance of BSFFF and commercial organic fertilizer (SAFI) on maize (H513) production. Both fertilizers were applied at the rates of 0, 2.5, 5, and 7.5 t ha-1, and 0, 30, 60, and 100 kg nitrogen (N) ha-1. Mineral fertilizer (urea) was also applied at 0, 30, 60 and 100 kg N ha-1 to establish the N fertilizer equivalence (NFE) of the organic fertilizers.

Climate Services for Resilient Development (CSRD) Partnership’s work in Latin America

Décembre, 2019
Colombia

The Climate Services for Resilient Development (CSRD)
Partnership is a private-public collaboration led by USAID,
which aims to increase resilience to climate change in
developing countries through the development and
dissemination of climate services. The partnership
began with initial projects in three countries: Colombia,
Ethiopia, and Bangladesh. The International Center for
Tropical Agriculture (CIAT) was the lead organization for
the Colombian CSRD efforts – which then expanded to
