Consumer demand heterogeneity and valuation of value-added pulse products: a case of precooked beans in Uganda
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/97153
Abstract
Background
This study investigated consumer demand heterogeneity and valuation of a processed bean product—“precooked beans” with substantially reduced cooking time. Common bean is the most important source of protein for low- and middle-income households in Uganda. Its consumption is, however, constrained by…

Quantifying process-based mitigation strategies in historical context: separating multiple cumulative effects on river meander migration
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/56598
Abstract
Environmental legislation in the US (i.e. NEPA) requires defining baseline conditions on current rather than historical ecosystem conditions. For ecosystems with long histories of multiple environmental impacts, this baseline method can subsequently lead to a significantly altered…

Drought Response in Wheat: Key Genes and Regulatory Mechanisms Controlling Root System Architecture and Transpiration Efficiency
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/89637
Abstract
Abiotic stresses such as, drought, heat, salinity, and flooding threaten global food security. Crop genetic improvement with increased resilience to abiotic stresses is a critical component of crop breeding strategies. Wheat is an important cereal crop and a staple food source globally.…

Whole genome sequencing of elite rice cultivars as a comprehensive information resource for marker assisted selection
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/66000
Abstract
Current advances in sequencing technologies and bioinformatics revealed the genomic background of rice, a staple food for the poor people, and provided the basis to develop large genomic variation databases for thousands of cultivars. Proper analysis of this massive resource is expected to give novel…

The role of crop diversification in improving household food security in central Malawi
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/91953
Abstract
Background
This paper concerns the role of crop diversification in improving household food security in central Malawi. In this country, the agricultural sector is dominated by smallholder farming and rain-fed food production systems that are facing increasing challenges from land degradation and declining soil fertility. Maize is…

Recommendation domains to scale out climate change adaptation in cocoa production in Ghana
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/103745
Abstract
Climate change is threatening cocoa production in West Africa and guidance towards site-specific adaptation is required. We developed recommendation domains with common degree of impact requiring incremental, systemic or incremental adaptation effort to provide decision support for interventions to scale out adaptive practices.…

Biosynthesis of cyanogenic glucosides in Phaseolus lunatus and the evolution of oxime-based defense
Bioversity-CIAT Alliance (Bioversity-CIAT Alliance)
https://hdl.handle.net/10568/108996
Abstract
Lima bean, Phaseolus lunatus, is a crop legume that produces the cyanogenic glucosides linamarin and lotaustralin. In the legumes Lotus japonicus and Trifolium repens, the biosynthesis of these two αâhydroxynitrile glucosides involves cytochrome P450 enzymes of the CYP79 and CYP736 families and a UDPâglucosyltransferase…

https://hdl.handle.net/10568/110033
Abstract
It is now well-documented that gene knockout (loss-of-function) alleles have played a prominent role in crop evolution during domestication, diversification, and improvement. This includes dramatic examples from the very origins of agriculture to the monumental yield increases of the Green Revolution. Recent advances in the…

Abstract
In this paper we aim to evaluate the effects of a 3-year resilience intervention (the SUR1M project in Niger) on the beneficiaries of the project. The evaluation was structured around the project's theory of change and designed to evaluate three elements along that theory of change: the types of responses beneficiaries…
