Collaborative Agrobiodiversity Governance
Agrobiodiversity governance, understood as the collective management and conservation of agricultural biodiversity through coordinated multi-stakeholder arrangements, is increasingly recognised as a cornerstone of sustainable food systems. When led by farmers, such processes hold potential to enhance rural food security and nutrition, conserve biocultural heritage, and sustain farming traditions over time. The Peruvian Andes, considered an agrobi…
Enhancing farmers’ access to neglected crop seeds for healthy diets in a changing climate
Food insecurity and poor diets undermine human health, livelihoods, and aspirations. Climate change further exacerbates the problem of achieving zero hunger. Promoting the production of a diverse portfolio of nutrient-dense, climate-resilient crops enables food supply for healthy diets in the coming years and decades. Many are underutilized even though they are considered opportunity crops, with an unrealized potential to improve food security an…
Varietal diversity and conservation status of banana, taro, pumpkin, and mustard green in mountainous areas of Northwest Vietnam
This study assesses the agrobiodiversity richness, traditional knowledge, and conservation status associated with four key crops—banana, taro, pumpkin, and mustard green—in Northwest Vietnam. Using the 5-cell method, 133 farmer varieties were identified in Mai Son and Sa Pa districts. Mai Son showed the highest level of varietal diversity in banana and pumpkin, while Sa Pa had the higher richness in mustard green and taro. Ethnic groups, particul…
Policy framing and crisis narratives around food safety in Vietnam
While progress has been made recently in understanding food systems per se, much less is known about policies around those food systems. In this paper, we aim at understanding the food system policy context with the specific objective to look at policy dynamics-defined as the way policy agendas are identified, justified, and framed by decision-makers, and how they interact. Vietnam is used as a case study. Primary data were generated through face…
Conceptualizing sustainable diets in Vietnam
Child stunting is associated with child, maternal, and environmental factors in Vietnam
Child stunting in Vietnam has reduced substantially since the turn of the century but has remained relatively high for several years. We analysed data on children 6-59 months (n = 85,932) from the Vietnam Nutritional Surveillance System, a nationally representative cross-sectional survey. Multivariable Poisson regression models were used to estimate relative risk (RR) of stunting, stratified by child age and ecological region. Covariates at the c…
The biodiversity of food and agriculture (Agrobiodiversity) in the anthropocene
When food systems meet sustainability – Current narratives and implications for actions
The concept of food system has gained prominence in recent years amongst both scholars and policy-makers. Experts from diverse disciplines and backgrounds have in particular discussed the nature and origin of the “unsustainability” of our modern food systems. These efforts tend, however, to be framed within distinctive disciplinary narratives. In this paper we propose to explore these narratives and to shed light on the explicit -or implicit- epi…
Multilevel Agrobiodiversity and Conservation of Andean Potatoes in Central Peru
Botanical species and morphological and genetic diversity represent different yet linked units of conservation. These features, and their spatial distribution in the central Peruvian Andean highlands of Huancavelica, were used as a basis for characterizing and quantifying potato agrobiodiversity at different scales. Results show that individual farm households maintain high levels of cultivar, morphological, and genetic diversity. At the regional…
