Impacts of resilience interventions – Evidence from a quasi-experimental assessment in Niger
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/105814
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…

Ground penetrating radar: a case study for estimating root bulking rate in cassava (Manihot esculenta Crantz)
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/83155
Abstract
Background
Understanding root traits is a necessary research front for selection of favorable genotypes or cultivation practices. Root and tuber crops having most of their economic potential stored below ground are favorable candidates for such studies. The ability to image and quantify subsurface root…

https://hdl.handle.net/10568/109682
Abstract
Heterogeneous and multidisciplinary data generated by research on sustainable global agriculture and agrifood systems requires quality data labeling or annotation in order to be interoperable. As recommended by the FAIR principles, data, labels, and metadata must use controlled vocabularies and ontologies that are popular in the…

Transformation in Practice: A Review of Empirical Cases of Transformational Adaptation in Agriculture Under Climate Change
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/97886
Abstract
Incremental adaptation may be inadequate to deal with rapid shifts and tipping points for food production under climate change. The concepts of transformative and transformational adaptation have emerged in recent years to address the need for major, non-marginal transitions in sectors, such as…

Genetic analysis of resistance to fusarium root rot in common bean
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/43481
Abstract
Fusarium root rot (FRR) is a major disease of common bean worldwide. Knowledge of the inheritance of resistance to FRR would be important in devising strategies to breed resistant varieties. Therefore, a 12 × 12 full diallel mating scheme with reciprocal crosses was performed to generate 132 F1 progenies, which were then advanced to the F3. The…

https://hdl.handle.net/10568/92857
Abstract
A diversity panel comprising of 296 indica rice genotypes was phenotyped under non-stress and water-deficit stress conditions during the reproductive stage in 2013 and 2014 dry seasons at IRRI, Philippines. We investigated the genotypic variability for grain…

Pullulanase Debranching of Various Starches Upgrades the Crystalline Structure and Thermostability of Starch‐Lauric Acid Complexes
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/93347
Abstract
Cassava, rice, and chickpea starches with different amylose contents and amylopectin structure are used to prepare helical inclusion complexes with lauric acid (LA) and to investigate the effect of pullulanase debranching on complex formation, crystalline structure, thermostability, and…

Abstract
Mineral deficiencies represent a global challenge that needs to be urgently addressed. An adequate intake of iron and zinc results in a balanced diet that reduces chances of impairment of many metabolic processes that can lead to clinical consequences. In plants, bioavailability of such nutrients is reduced by presence of…

Abstract
Two populations of interspecific introgression lines (ILs) in a common recurrent parent were developed for use in pre-breeding and QTL mapping. The ILs were derived from crosses between cv Curinga, a tropical japonica upland cultivar, and two different wild donors, Oryza meridionalis Ng. accession (W2112) and Oryza…
