Improving food-system efficiency and environmental conservation using agricultural biodiversity in Busia County: a pilot study

Abstract Background Despite the abundance of edible biodiversity, both wild and cultivated, malnutrition and food insecurity persist in Busia County, Kenya, where poverty indices range from 63% to 74% and 25% of children younger than 5 years are stunted, 11% are underweight, and 4% are thin for their age. Much of this biodiversity, used in traditional food preparations, has the potential to provide access to key micronutrients for healthy and balanced diets and to act as an important source of community resilience to climate change and economic turbulence. Yet, low consumer awareness of the value of local biodiversity, poorly developed value chains, and negative perceptions of traditional foods have led to the disappearance of many nutrient-rich species and the shift to unhealthy diets. We aimed to show that heightened knowledge of the value of biodiversity and improved value-chain efficiencies can help to conserve biodiversity and improve local food systems. Methods We developed a farmer business school model and provided training to 25 farmer groups across seven sub-counties in Busia County, Kenya, on the sustainable production of traditional vegetables, post-harvest handling, contract farming, nutrition, and value addition. We also analysed selected species for nutritional content, tested a food procurement model supporting market linkages between farmers and local institutions, and carried out nutrition education activities to improve the capacity of schools and clinics to incorporate traditional foods into meals. Findings We found that traditional vegetables were rich in iron—for example, cowpea leaves contained 17 times more iron than did kales. After making the nutritional data available to all value chain actors during implementation of the food procurement model, we recorded a 12% increase in the number of households cultivating local biodiversity, both for household consumption and off-farm sales, along with a 75% increase in the plot size devoted to traditional vegetable cultivation. Furthermore, household incomes increased by a mean of 47% (SD 30) as a result of direct links with institutional markets. The effects of increased market linkages on education, economic, and health benefits will be measured in a second phase of the project to start in 2018. Interpretation The project has positively affected the abundance, composition, and distribution of species and revived interest in local food biodiversity, in addition to producing benefits around diverse diets. Experience in implementing the Busia model has been used to inform global policies that aim to mainstream biodiversity in sustainable food systems using public procurement, particularly schools, as a platform for improving nutrition. Nationally, a biodiversity policy was developed for Busia County that recognised the importance of local biodiversity, including for improved livelihoods, community resilience, and health and nutrition.

The potential of neglected and underutilized species for improving diets and nutrition

The paper highlights the novel and ingenious approaches Brazil, Kenya, Sri Lanka and Turkey used to prioritize a rich diversity of NUS for healthier diets and improved nutrition, and how this knowledge was used to mainstream these plant species into production and consumption systems. The paper concludes with some perspectives on the way forward for NUS and the community working on them in meeting the challenges of malnutrition and environmental sustainability in the 2030 sustainable development context

School meals and food systems: Rethinking the consequences for climate, environment, biodiversity, and food sovereignty

There is an urgent need to rethink our global food systems. The world is facing a nutrition crisis, and the way we produce and consume food is altering the equilibrium of our planet, causing environmental damage and biodiversity loss, and climate change which further compromises food security. Children are disproportionately affected, and school meals are being increasingly recognized as a key investment for governments to tackle these challenges. Through national school meals programs, around 418 million children currently receive a meal at school every day. This provides an exceptional opportunity for the implementation planet-friendly policies which have enormous co-benefits for child health and the wider society. To explore these opportunities, this White Paper was prepared by The Research Consortium for School Health and Nutrition, an initiative of The School Meals Coalition (SMC), a multilateral coalition of 95+ countries aiming to improve and expand national school meal programs for all children. The White Paper, written in collaboration with 85 organizations worldwide, explains how implementing planet-friendly school meal programs can provide far reaching co-benefits for public health and human capital. The paper proposes that to maximize the transformative potential of school meal programs, governments should focus on two sets of policies. First, those that can create immediate benefits for children and the planet, including: adopting nutritious, diverse, whole foods menus; switching to clean, efficient and sustainable energy for cooking; minimizing food and package waste; and empowering children by establishing life-long healthy and sustainable food habits through holistic food education. Secondly, leveraging the power of procurement, governments can create demand-driven changes to support sustainable ecological and regenerative agriculture practices, which promote biodiversity, resilience, and food sovereignty
