Consumers' evaluation of volition, control, anticipated regret, and perceived food health risk
Edible insects are a potentially less burdensome source of proteins on the environment than livestock for a majority of rural consumers. Hence, edible insects are a timely idea to address the challenges of the supply side to sustainably meet an increasing demand for food. The objective of this pa...

Intentions to consume foods from edible insects and the prospects for transforming the ubiquitous biomass into food
Malnutrition, particularly vitamin A deficiency, is a major public health problem in many developing countries. This study investigated whether priming or self-generation of goals, or whether attention to instrumental or experiential goals together with use of a reminder condition or not, promote...

Purpose – Potato is a major food staple in Africa, but its production is constrained by poor quality of seed. A recent private–public partnership in Tanzania resulted in introduction of new higher yielding varieties. The purpose of this paper is to examine smallholder farmers’ motivations to inve...

In the coming decades, feeding the expanded global population nutritiously and sustainably will require substantial improvements to the global food system worldwide. The main challenge will be to produce more food with the same or fewer resources. Food security has four dimensions: food availabil...
