Water yam (Dioscorea alata), also known as winged yam, is one of the most economically significant yam species, serving as a staple food crop in tropical and subtropical regions. Its widespread cultivation is due to its favorable agronomic characteristics, including high yield, improved tuber storability, and significant nutritional and health benefits. Despite these advantages, water yam often remains underutilized due to consumer biases towards its traditional food product quality, particularly ...

Climate-Smart Cocoa (CSC), a strategic offshoot of the wider Climate-Smart Agriculture, is gaining ground in Ghana, a cocoa export-dependent country. CSC is imperative, given the rapidly declining forests, prolonged periods of drought, pest and disease infestations, and fluctuating cocoa yields attributed to climate variability and change. Although many interventions are instituted to restore sustainable cocoa production, they are largely technicist because they do not pay attention to gender ...

Climate change is predicted to significantly reduce areas suitable for the cultivation of cocoa, an important cash crop providing a livelihood to over six million smallholders in the humid tropics. Cocoa agroforestry shows potential to increase climate resilience while providing more stable incomes, enhancing biodiversity, supporting healthy ecosystems and reducing the pace at which farms expand into forested areas. Based on the multidisciplinary ‘Climate Smart Cocoa Systems for Ghana’ research ...

High yielding and stable early maturing provitamin A (PVA) maize hybrids with combined stresses (drought and heat and Striga) tolerance are needed to combat malnutrition, low yield and insecurity in sub-Sahara Africa (SSA). To address this need, PVA, PVA-QPM (quality protein maize) inbred lines with Striga and drought tolerant genetic make-up were developed through the massive effort of the International Institute of Tropical Agriculture Maize Improvement Program (IITAMIP) for its hybrid ...

As a first step to determine the focus of potential genetic improvement programs for African catfish in Nigeria, we conducted a study to identify the preferred attributes among catfish producers across three states renowned for aquaculture production, in December 2022. Employing a qualitative approach, data were collected through 11 focus group discussions involving 123 participants. The findings indicate that farmers prioritize a range of catfish attributes related to both consumption and production. ...

In many African countries, land access and tenure insecurity pose significant challenges to agriculture, in particular for the youth. As the farming population ages, young people are expected to take over, but they don't often show much interest in farming, which could harm the future of agriculture in Africa, where the population is the youngest. Land reforms and titling programs are suggested as amongst strategies to make agriculture more attractive to investors and promote youth involvement. ...

The Purdue Improved Crop Storage (PICS) bag is often associated with preventing grain damage from insect infestation, reducing aflatoxin accumulation in stored grain, and avoiding exposure to hazardous storage chemicals. However, limited knowledge is available on the information channels driving the adoption of the technology. Using data from 429 households, this study examines the impacts of social learning and extension services on the speed of adoption of PICS bags in Tanzania. We utilized the ...

Cassava (Manihot esculenta Crantz) is an essential crop with increasing importance for food supply and as raw material for industrial processing. The crop is vegetatively propagated through stem cuttings taken at the end of the growing cycle and its low multiplication rate and the high cost of stem transportation are detrimental to the increasing demand for high-quality cassava planting materials. Rapid multiplication of vegetative propagules of crops comprises tissue culture (TC) and semi-autotroph ...
