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, promotes dietary behaviour intentions and change. A set of 556 randomly selected children aged 7-12 in Osun state, Nigeria, participated in an four-week intervention and field experiment in which a meal based on orange-fleshed sweetpotato, rich in pro-vitamin A, was introduced on five occasions as a complement to the existing school meal. Baseline intentions, anticipated feelings and repeated measures of post-consumption and experience were assessed. The analyses included a generalised linear mixed model for consumption and a linear mixed model for feelings and experience. The results confirmed that attention to instrumental goals undermines goal pursuit, while a focus on experiential goals increases the persistence of pursuit. Priming of experiential goals should be recommended, especially because this approach evokes positive feelings after eating. There was no evidence of an effect from repeated pairing of goals with the school meal, but use of planning by stating intentions increased the amount eaten. These results have implications for how school meals programmes should be designed to better align personal motivation with behavioural change in relation to dietary health.

Sweet potato (Ipomoea batatas L.) was not an important crop in Ghana, Burkina Faso and Nigeria, West Africa, in the past decades. An effort has been made to reposition the sweet potato crop in West Africa. Orange-Fleshed Sweet potato (OFSP) cultivar was used as an entry point while properly designing a market-driven approach in the research project, ‘Jumpstarting OFSP in West Africa through diversified markets’. The project was implemented in these three countries in the period of April 2014 throughout March 2017. There is a clear indication that sweet potato is shifted from an orphan crop into a commercial one in these project areas. Obviously, the sweet potato crop has significantly become an important crop among other commercial agricultural commodities in the localities. Additionally, as the OFSP cultivars have already well known for its contribution to food and nutrition security, as well as to a wealth. Hence, the sweet potato crop will give great opportunities to people to improve their livelihood along with healthy life, particularly in the drought-prone regions where the homes of most resourcepoor farmers, and where the sweet potato crop is grown and consumed most. Establishment of various market models evidently played an important role to support this effort.
Commercialization of sweetpotato vines is persistent if multipliers show evidence of superiority of their vines. This study aimed at evaluating the effects of net tunnel source and of pathogen-tested planting material compared to “apparently” healthy vines on yield and health status at three defined environments in Northern Ghana during the rainy season of 2015. Sweetpotato virus disease (SPVD) and weevils were considered. Four varieties were investigated, the pathogen-tested vines of Dadanyuie, Bohye and Ligri, and “apparently” healthy vines of Apomuden from the negative selection technique. All planting materials taken from the net tunnel and open field were from the same location. Eight treatment combinations were arranged in a RCBD with 3 replicates. Planting distance was 0.30 m x 1 m. Weeding was done and fertilizer was applied as necessary. General and three-way analysis of variance were computed using Genstat. Highly significant differences were found among varieties and trial sites for plant establishment, foliage yield, root yield, weevil, and SPVD. The two sources were showed non significant difference. For varieties across sites, net tunnel source was better than open field. The apparently healthy vines might be effective as pathogentested vines. Net tunnels may have a distinct advantage for multiplication and maintenance.

This facilitator guide is meant for the user of the Orange-Fleshed Sweetpotato (OFSP) Counselling Cards, developed for use in the Ghana Health Service’s antenatal care program. This facilitator guide and counselling cards were developed under the project Jumpstarting Orange-fleshed Sweetpotato in West Africa through Diversified Markets, drawing on available materials and adapting them for use in Ghana. They fall within the framework of the Essential Nutrition Actions (ENAs) of UNICEF with respect to the Scaling up the Nutrition movement in West Africa.

This presentation is meant to promote the work on orange-fleshed sweetpotato in West Africa, and particularly in Ghana. Through diversified markets, the planting material can be valued; it benefits resource-poor farmers to generate income (poverty alleviation), improved nutrition of vulnerable people including people living with HIV and AIDS, and for food security.
