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.

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.

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.

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. Doctor of Philosophy Though we usually think of hunger in terms of not getting enough to eat, there is another form, known as 'hidden hunger', which refers to not eating enough of the right types of foods. This results in not getting enough of the nutrients, such as iron or vitamin A, that are essential for human health and development. People living in low- and middle-income countries (LMICs) are especially vulnerable to this type of hunger, as their diet typically is comprised of calorie-rich but nutrient-deficient foods. One of the most effective ways to reduce hidden hunger, is to eat a variety of foods that are rich in micronutrients (e.g., fruits, vegetables, legumes, meat). In LMICs, governmental and non-governmental organizations (NGOs) have created programs to encourage this so-called 'diet diversity' by encouraging households to produce different types of food crops or plant kitchen gardens. These programs have been successful in increasing diet diversity, however, significant portions of the population in LMICs still lack diversity in their diets. We now know that an increasing number of low-income households in LMICs are purchasing at least some of their foods from markets. Thus, there is increasing interest in the role that businesses and food purchases can play in increasing the diversity of the diet among households that may be suffering from hidden hunger. The purpose of this research was to explore this possibility. First, I investigated if low-income consumers are already purchasing diverse foods from the market in Mozambique, and, if they are, how much are they willing to pay for this diversity. Second, I explored how the diversity of these purchases are related to what individuals believe about the connection between diet diversity and health. Then I conducted a community-based intervention, where low-income households participated in a nutrition and food-purchasing education and worked with facilitators to find ways that worked for them to increase the diversity of the foods they purchased from the market. The findings of this study show that it may be possible to use the market and food purchases to increase the diet diversity of low-income households, but that support from governments and NGOs will likely be required in order to be successful in reducing hidden hunger in the long-term.

Market based solutions for addressing nutritional deficiencies are based on the fact that the poor procure a portion of food from markets. However, it is not clear if commercial business models can be implemented in low-income markets. A value chain analysis is applied and finds that cost management strategies can produce sustainability and scale. There is also little evidence to substantiate if poor consumers value nutritious products and will consume them in adequate amounts. An RPL and RE model are used to conduct a willingness-to-pay analysis. Nutritional benefit is valued over other attributes of a fortified yogurt product. WTP values are most highly influenced by factors of nutritional awareness and acceptability. A binary response model is used to analyze adequacy of consumption. The most influential factors are related to acceptability, availability and channel of delivery. Together these elements help identify if business models can be used as a nutritional intervention.
