Abstract
This experiment was designed to determine the economic damage on cassava caused by different population levels of Phyllophaga menetriesi in the Cauca Department of Colombia. The experimental units consisted of one stem cutting and four densities of the insect in third instar (one, three, five and seven grubs)…

Experiential learning, narrative‐based learning, and insurance adoption: Experimental evidence from Kenya
https://hdl.handle.net/10568/173667
Abstract
We compare the impact of two extension modalities on knowledge accumulation and willingness to pay for a weather index insurance product among smallholder farmers in Kenya. One approach to extension is based on experiential learning and involves participation in an incentivized framed experiment (or game). The other is based on conventional “narrative-based” learning. While both…

Abstract
Crop diversity conserved in genebanks facilitates the development of superior varieties, improving yields, nutrition, adaptation to climate change and resilience against pests and diseases. Cassava ( Manihot esculenta ) plays a vital role in providing carbohydrates to approximately 500 million people in Africa and other continents. The International Center for Tropical Agriculture (CIAT) conserves the…

Suitability of root, tuber, and banana crops in Central Africa can be favoured under future climates
https://hdl.handle.net/10568/114704
Abstract
Context Climate change is projected to negatively impact food systems in Sub-Saharan Africa. The magnitude of these impacts is expected to be amplified by the extensive reliance on rainfed agriculture and the prevalence of subsistence farming. In the Great Lakes Region of Central Africa, smallholder farming households are largely dependent on root, tuber and banana crops. However, the…

Moth bean (Vigna aconitifolia): a minor legume with major potential to address global agricultural challenges
https://hdl.handle.net/10568/138382
Abstract
Moth bean (Vigna aconitifolia) is an orphan legume of Vigna genus, exhibiting wide adaptability and has the potential to grow well in arid and semi-arid areas, predominantly across different eco-geographical regions of Asia, particularly the Indian subcontinent. The inherent adaptive attributes of this crop have made it more tolerant towards a diverse array of abiotic and biotic…

Abstract
The Interspecific Urochloa recurrent selection breeding programme at CIAT aims to integrate desirable traits such as resistance and tolerance to spittlebugs (Hemiptera: Cercopidae), the main insect pest affecting these pastures in Latin America. Eleven successive cycles of selection were screened for antibiosis and tolerance to Aeneolamia varia…

Abstract
Common bean is the world’s most important directly consumed legume food crop that is popular for calories, protein and micronutrients. It is a staple food in sub-Saharan Africa, and a significant source of iron for anemic people. However, several pests, soil and weather challenges still impede its production. Long cooking time, and high phytic acid and polyphenols that influence…

Abstract
Common bean has a high sensitivity to drought stress, particularly during reproductive development which reduces its yield. In this study we aimed to: (i) evaluate differences in shoot and root response of a mapping population of 107 recombinant inbred lines (RILs) of SEA 5 × AND 277 cross under drought stress, and (ii…

Abstract
In this paper we revisit the current debate between red meat vs. alternative protein and explore the respective contribution that those two polarized discourses claim to make in relation to the new international agenda on transforming food systems toward a more sustainable future. To complete this, we combine classical political economy analysis focusing on the access and…

Abstract
Cassava is a tropical crop that provides daily carbohydrates to more than 800 million people. New cassava cultivars with improved yield, disease resistance, and food quality are critical to end hunger and reduce poverty in the tropics. However, the progress of new cultivar development has been dragged down by difficulties obtaining flowers from desired parental plants to enable designed crosses. Inducing early flowering and…
