“…Consumers that were well informed about the nutritional benefits were willing to pay 51% more for OFSP than for white-fleshed sweet potato in Mozambique (Naico and Lusk, 2010) and 25% more in Uganda (Chowdhury et al, 2011), while without prior nutritional information this is not the case. This corresponds with results of a meta-analysis of 23 studies that shows consumers are willing to pay 21% more for biofortified crops (De Steur et al, 2017).…”

“…In combination with evidence of effectiveness for alleviating micronutrient deficiencies, this kind of contextual research may be used to support scaling up activities and innovations to promote sustainable uptake of the new crop. In the biofortification literature, stakeholder perceptions, consumer acceptance and willingness to pay have been assessed using a range of interdisciplinary methods, such as SWOT (strengths, weaknesses, opportunities and threats) analysis, sensory evaluation, experimental auctions and revealed choice experiments [13][14][15]. However, very few studies have conducted in-depth qualitative studies with local community stakeholders to identify relevant contextual factors and potential challenges prior to implementation.…”

Background: Biofortification of staple food crops may be a cost-effective and sustainable approach to reducing micronutrient deficiencies in resource-poor settings with low dietary diversity. However, its success depends on uptake by the local population. This paper presents formative research conducted in a remote, rural community in North West Pakistan, prior to commencing a randomised controlled trial to test the effectiveness of consuming zinc-biofortified wheat flour for alleviating zinc deficiency. It explored local community members' knowledge, understanding and attitudes towards biofortification and views on members of their community taking part in the trial. Methods: Four focus group discussions were conducted with male and female community members (separately for cultural reasons) and four in-depth interviews were conducted with Jirga members-respected male elders. Participation was limited to households that were ineligible for the trial so that we could explore the perspectives of community members who were not influenced by the incentives of the trial. Focus group participants were selected at community events for transparency. Data collection took place at the local school and homes of Jirga members. Thematic analysis was undertaken, using a combination of deductive and inductive approaches to identify key themes. Results: A total of 47 men and women participated in this study. Participants reported clear motivation to access and consume more nutritious flour, believing this would bring health benefits, particularly to women and children. Trusted members of the local community, including Jirga members and female health workers, should be involved in providing information on biofortified flour (and the trial) to increase levels of awareness and acceptance. Without their involvement, there is a risk that biofortified flour would be mistrusted. The cost of flour is the main factor affecting purchasing decisions, and biofortified flour will need to be cost-competitive to achieve widespread uptake in marginalised, rural communities. Conclusion: This formative study generated rich, qualitative data from a range of community stakeholders to improve the understanding of important barriers and facilitators to the widespread acceptability and adoption of biofortified wheat. Implementation research such as this will inform future decision-making in relation to scaling up biofortified wheat in Pakistan.

“…The currently existing stakeholder literature on biofortification has mainly concentrated on consumers (see reviews of Birol et al; De Steur et al; and Talsma et al [ 14 , 15 , 16 ]). These reviews synthesized studies on consumers’ evaluation of biofortified foods by applying sensory evaluation, hedonic trait analyses or economic valuation methods (i.e., willingness-to-pay).…”

Stakeholders’ Perceptions of Agronomic Iodine Biofortification: A SWOT-AHP Analysis in Northern Uganda

Agronomic biofortification (i.e., the application of fertilizer to elevate micronutrient concentrations in staple crops) is a recent strategy recommended for controlling Iodine Deficiency Disorders (IDDs). However, its success inevitably depends on stakeholders’ appreciation and acceptance of it. By taking Northern Uganda as a case, this study aimed to capture and compare the perceptions of seven key stakeholder groups with respect to agronomic iodine biofortification. Therefore, we employed a SWOT (Strength, Weaknesses, Opportunities & Threats) analysis in combination with an Analytical Hierarchy Process (AHP). Findings show that stakeholders (n = 56) are generally positive about agronomic iodine biofortification in Uganda, as its strengths and opportunities outweighed weaknesses and threats. Cultural acceptance and effectiveness are considered the most important strengths while the high IDD prevalence rate and the availability of iodine deficient soils are key opportunities for further developing agronomic iodine biofortification. Environmental concerns about synthetic fertilizers as well as the time needed to supply iodine were considered crucial weaknesses. The limited use of fertilizer in Uganda was the main threat. While this study provides insight into important issues and priorities for iodine biofortification technology in Uganda, including differences in stakeholder views, the application of the SWOT-AHP method will guide future researchers and health planners conducting stakeholder analysis in similar domains.
