    Buying to Thrive: Exploring the Potential for Market-Based Approaches to Contribute to Increases in Diet Diversity in Mozambique
    Agnew, Jessica L. (Virginia Tech, 2020-08-04)
    Globally, more than two billion people suffer from deficiencies in micronutrients that are essential for human health. Low-income populations in low- and middle-income countries are especially vulnerable to these deficiencies. There are three priority interventions used to reduce micronutrient deficiencies and improve overall nutrition status — supplementation, fortification, and diet diversity. As the share of food purchases made by low-income households has been increasing, there is increasing interest in the role the private sector can play in these interventions. Currently, there is little known about the potential for a market-based approach to contribute to improvements in diet diversity. Proven to be one of the most effective ways of improving nutritional status, increasing diet diversification among low-income populations will be essential for reducing micronutrient deficiencies in the long-term. The purpose of this research is to contribute evidence on the potential for a market-based approach to increase diet diversity among low-income households in Mozambique. This research starts by examining the extent to which low-income consumers in Nampula, Mozambique make diverse food purchases and the amount they are willing to pay for such diversity. Since diet diversification is intended to improve health, the connections between individual-level health constructs and diversity of food purchases is subsequently investigated. These studies are then used as the basis for a participatory community-based intervention that explores if health constructs influence modifications in food purchases and the barriers and enabling factors that exist to using the market to increase household diet diversity. The findings of this work reveal that there is potential for markets to contribute to the diversity of foods consumed by low-income households; however, concerted efforts between the private, public, and civil sectors will likely be required for the success and longevity of market-based approaches.

    Embedded Research Translation Report: Exploring the Use of Blockchain Technology to Promote the Production and Consumption of African Indigenous Vegetables in Western Kenya
    Kristofikova, Nurvitria; Muskoke, Irene; Agnew, Jessica L. (AgUnity, 2021-08-04)
    AgUnity worked with Virginia Tech and Egerton University on the LASER PULSE-funded project entitled Exploring the Use of Blockchain Technology to Promote the Production and Consumption of African Indigenous Vegetables (AIVs) in Western Kenya. AIV value chains are characterized by transactional and informational inefficiencies that contribute to inconsistent supply and mismatched demand in Kenya. This research program explores how digital applications built on blockchain technology (BCT) can be deployed in AIV value chains in western Kenya, in a way that improves food and nutrition security for all value chain actors. Specifically, there was interest in understanding how the BCT-based smartphone application could assist groups of individuals who typically face constraints in accessing economic or nutritional benefits from value chain upgrading (i.e., smallholder producers, women, youth, low-income consumers). This project was one of the first times the AgUnity app was not deployed in a centralized supply chain context (i.e., with a union or cooperative supplied by hundreds of farmers). We have found that in decentralized supply chains, there is a particular need to ensure that the system supports the users' values and needs for conducting their respective value chain activities. When this is achieved, trust that is garnered through the use of the technology shall translate directly into more cooperative and coordinated value chains. Both the value chain app adaptation and configuration and the technology service design were built around this premise, using embedded research translation (ERT) processes to ensure that it was achieved in the target population and value chain. This report outlines the steps taken by AgUnity to translate Virginia Tech and Egerton University’s research into the adaptation and deployment of our proprietary BCT-based smartphone application. It is directed toward readers interested in understanding the product and service design of the AgUnity application, the use of BCT in digital platforms designed for last-mile users, and those interested in successful examples of ERT. It walks the reader through the value chain mapping and community immersion processes, the steps needed to adapt the technology to fit the local value chain context, and the development and selection of app functionalities for the target users and value chain. The report may be of interest to researchers, farming associations, and cooperatives or agricultural non-governmental organizations interested in the AgUnity solution as well as stakeholders involved in strengthening agricultural market systems, AgTech, or FinTech.

    Filling the GAPs: Expert Essays
    Thompson, Tommy; Grove, Ben; Archibald, Thomas G.; Agnew, Jessica L.; Steensland, Ann (2020-10-12)
    Agricultural productivity is best expressed as Total Factor Productivity-TFP. TFP is a measure of efficiency in agriculture — the efficiency with which agricultural inputs such as labor, fertilizers and seeds are converted into outputs of crops and livestock. According to the the Global Agricultural Productivity Index (GAP Index), global TFP must increase by 1.73 percent annually to meet global goals for adequate food, feed, fiber, and biofuel for 10 billion people by 2050. When we fall short of this target growth rate, as we have each year since the GAP Index was developed in 2010, this creates a “productivity gap”. The productivity gap is worsening in the world’s poorest countries, where TFP growth now averages only 0.58 percent annually. The productivity gap threatens food security and often forces farmers to cultivate marginal lands, which can also threaten biodiversity. How do we close the productivity gap and get back on track to achieving global food security? This year, the GAP Report editors invited scholars and experts to submit essays based upon their research about strategies for closing the productivity gap and increasing agricultural sustainability and resilience.

    The Impact of Blockchain Technology on Food Insecurity through African Indigenous Vegetables in Western Kenya: Final Report
    Agnew, Jessica L.; Hall, Ralph P.; Mwangi, Joseph; Sumner, Daniel M.; Kristofikova, Nurvitria (USAID LASER PULSE, 2022-05-16)
    This study is one of the first to explore how blockchain technology (BCT) could be used to improve food security in communities that are reliant on agriculture but are the last to receive services or access to markets, known as the ‘last-mile’. The goal was to determine how BCT could contribute to improving the income of African indigenous vegetable (AIV) value chain actors (e.g., producers, traders, and retailers) and to the affordability, availability, and accessibility of nutritious foods like AIVs for consumers. It finds that BCT can simultaneously strengthen the functionality of an entire agri-food value chain by increasing the efficiency of transactions among value chain actors, improving cooperation along the value chain, and enhancing access to information. A decrease in post-harvest loss, reduction in negotiation and search costs, and traceability of Grade A vegetables were facilitated by the blockchain functionality of the AgUnity V3 SuperApp. Producer income was improved by better meeting market demand, time savings on AIV activities, increasing the supply of Grade A vegetables, and making information on the vegetables more available to consumers. Increased incomes led to improved food security among producers by facilitating their ability to procure more food, especially higher quality proteins and fruits. Participants and consumers reported an increase in the consumption of AIVs over the study period because of increased quality, availability, and awareness of their nutritional importance.

    Transaction and Information Pain Points in African Indigenous Vegetable Value Chains in Western Kenya: A Gender-Responsive AIV Value Chain and Market Analysis Report
    Agnew, Jessica L.; Mwangi, Joseph; Hall, Ralph P.; Sumner, Daniel M.; Kristofikova, Nurvitria (2021-08-23)
    The use cases for blockchain technology (BCT) have taken off since its initial development for the cryptocurrency Bitcoin. In agricultural value chains, BCT has been developed for agri-food products from source to retail outlets, increasing transparency between value chain actors, and creating secure transaction platforms. However, BCT is not a magic bullet for addressing all value chain inefficiencies and challenges. This study, Exploring the Use of Blockchain Technology to Improve Food Security Through African Indigenous Vegetables in Western Kenya, aims to investigate the types of challenges within the value chain for African indigenous vegetables (AIVs) that BCT is appropriate to address. It also aims to investigate if deploying a BCT-based digital platform in AIV value chains will lead to improved food security for all value chain actors. This gender-responsive participatory value chain analysis (PVCA) investigates the transactional, informational, and other types of pain points within AIV value chains to identify where BCT is needed. AIVs are known as ‘female’ crops, as women are primarily responsible for their production, marketing, and preparation. This PVCA also investigates gender disparities in the value chain with the view to understanding how a BCT-based digital platform might help to secure the place of women in the value chain as it is upgraded. According to the findings of the PVCA, the main pain points that need to be addressed in order to improve income-earning opportunities and availability of and demand for AIVs are the lack of coordination throughout the value chain, assurance of vegetable safety for consumers, improved transmission of information through the value chain, standardization of grading and pricing, improving the market power of women, and technical assistance for producers in pest and disease management and production practices to improve yield. BCT cannot address all of these pain points. However, it is well suited for improving vertical coordination between actors by organizing and standardizing transactions and making information on the AIVs accessible at all stages of the value chain. It will also provide women a safe and secure platform for transacting that will protect the revenues earned from their respective activities. This study also finds that while smartphone ownership is low, value chain actors are willing to pay for a smartphone as well as a monthly subscription fee to use a digital platform if it will address their key pain points. This study will continue to investigate key knowledge gaps such as how technology use might more effectively engage youth in AIV value chains, how information on the blockchain can be certified, and how to scale up the use of a BCT-based digital platform. However, this PVCA demonstrates there is potential for BCT to offer important solutions to address transactional and informational inefficiencies along AIV value chains.

    Virginia Tech Food Access and Security Study
    Hall, Ralph P.; Ranganathan, Shyam; Agnew, Jessica L.; Christie, Maria Elisa; Kirk, Gary R.; Lucero, Christian; Clark, Susan F.; Archibald, Thomas G. (Virginia Tech, 2019-10-30)
    There is growing evidence to suggest that a substantial number of college and university students in the United States grapple with food insecurity during their studies. One of the most comprehensive surveys on this issue was conducted by The Hope Center with 33 participating four-year institutions. They estimated that 41% of students had low or very low food security (Goldrick-Rab et al. 2019). A review of food security studies by the U.S. Government Accountability Office (GAO) (2018) found similar results and that few students who qualified for food assistance were aware of federal food assistance programs such as the Supplemental Nutritional Assistance Program (SNAP). In response to the increasing concern over students’ access to food, this study aims to document food security at Virginia Tech. The study was designed with two parallel goals: to contribute to the national conversation on food access and security amongst higher education students; and to inform a strategic response through data-informed programs and policies at Virginia Tech. The first phase of the study was conducted between Fall 2017 and Spring 2018 and consisted of semi-structured key informant interviews. The second phase was conducted between December 2018 and January 2019 and consisted of an anonymous survey distributed to 32,242 students (27,421 undergraduate and 4,821 graduate) located in Blacksburg. A total of 2,441 (8.9%) undergraduate and 589 (12.2%) graduate students completed the entire survey (for a combined response rate of 9.4%). This study finds that 29% (±3.8%) of undergraduate and 35% (±7%) of graduate students were classified as having low or very low food security based on the USDA food security instrument. These findings are comparable with The Hope Center study (Goldrick-Rab et al. 2019). Students with low/very low food security status were more likely to be Hispanic/Latino or Black/African American, be receiving a Pell grant or financing their education through sources that need to be repaid, have a low GPA, and/or have a disability. Graduate students were also more likely than undergraduate students to be unable to afford to eat balanced meals or have to cut the size of their meals due to a lack of available funds. In general, the proportion of graduate students experiencing food-access problems was greater than the proportion of undergraduate students. A diet diversity score (DDS) was also developed from the student survey to measure the foods consumed by an individual within the previous 24 hours. The DDS is a proxy for dietary quality and helps provide insight into the barriers that students might face in accessing nutritious foods. The study found that on average students classified as having low/very low food security also had a lower DDS. This finding confirms that low food security is associated with a lower diet quality in addition to not having access to enough food. Students who reported that they sometimes or often did not have enough to eat in the past 12 months were also asked if they have received benefits from a range of food assistance programs. Of the 219 students who were asked this question, only 9% (n=20) reported receiving some form of assistance. When asked why they had not used a food assistance program, the primary response was that they felt other people needed more assistance than they did. The next three most selected reasons were a lack of awareness about (1) whether they were eligible for a food assistance program, (2) what programs exist, and (3) whom to speak with about what resources are available. These findings are consistent with the GAO (2018) report. These results reveal that students who potentially need food assistance may not know where to look for help, and administrative and/or social barriers related to existing on- and off-campus services may prevent students from seeking help even if they know it is available. This report also documents a range of on- and off-campus food assistance services that are available for students and provides a summary of the feedback obtained from the key informant interviews on potential next steps that could be taken by Virginia Tech. These steps include enhancing the coordination among, and awareness of, existing food assistance programs on and off campus, and new ideas such as creating an on-campus food pantry or subsidizing the cost of dining for students in need. Regardless of which actions are taken, we believe this report reveals our collective responsibility to ensure that no student at Virginia Tech goes hungry or is unable to access nutritious foods, and to create a community that nurtures learning and growth for all of its members.

    Women, Smartphones, and Leafy Greens: How ICTs support women producers in Western Kenya to secure their position in commercializing value chains for indigenous vegetables
    Agnew, Jessica L.; Sumner, Daniel M. (Virginia Tech, 2022-02-10)
    In Western Kenya, women are actively engaged throughout all stages of African indigenous vegetable (AIV) value chains. AIV production and marketing are important means for women to generate economically viable livelihoods and support their families’ nutrition and food security. Enhancing the efficiency and productivity of AIV value chains have the potential to enhance the accessibility of AIVs and enhance the income of women participating in the value chain. However, gender and other factors affect women’s ability to benefit from upgrading activities and improve or maintain their position in the value chain. In this discussion, we will examine how access to information communication technologies such as smartphones, the internet, and blockchain can help to secure the place of women in better functioning AIV value chains in Western Kenya.
