The concept of food system has gained prominence in recent years amongst both scholars and policy-makers. Experts from diverse disciplines backgrounds have particular discussed the nature origin "unsustainability" our modern systems. These efforts tend, however, to be framed within distinctive disciplinary narratives. In this paper we propose explore these narratives shed light on explicit -or implicit- epistemological assumptions, mental models, paradigms that underpin those. analysis...
Crop wild relatives have a long history of use in potato breeding, particularly for pest and disease resistance, are expected to be increasingly used the search tolerance biotic abiotic stresses. Their current future crop improvement depends on their availability ex situ germplasm collections. As these plants impacted by habitat destruction climate change, actions ensure conservation become ever more urgent. We analyzed state 73 closest (Solanum section Petota) with aim establishing...
Seed systems for roots, tuber, and banana (RTB) crops receive relatively little attention from development-oriented research commercial seed sector actors, despite their importance food security, nutrition rural livelihoods. We review RTB systems—with particular reference to potato, sweetpotato, cassava, yam —to reflect on current system development approaches the unique nature of these systems. refer our own experiences, literature 13 case studies interventions identify gaps in knowledge...
Crop wild relatives of sweetpotato [Ipomoea batatas (L.) Lam., I. series Batatas] have the potential to contribute breeding objectives for this important root crop. Uncertainty in regard species boundaries and their phylogenetic relationships, limited availability germplasm with which perform crosses, difficulty introgression genes from has constrained utilization. Here we compile geographic occurrence data on relevant produce distribution models species. We then assess comprehensiveness ex...
Cassava mosaic disease, one of the ten most economically important crop viral diseases in world, was first reported Southeast Asia from a single plantation Cambodia 2015. To determine presence and incidence Sri Lankan cassava virus (SLCMV) year after detection, total 6,480 samples 419 fields were systematically collected production areas across (3,840 samples; 240 fields) Vietnam (2,640samples; 179 2016 cropping season. Using PCR-based diagnostics, we identified 49 SLCMV-infected plants nine...
Cassava is one of the most important annual crops in Southeast Asia, and faces increasing seed borne pest disease pressures. Despite this, cassava systems have received scant research attention. In a first analysis Vietnamese Cambodian systems, we characterized existing 2016-17 through farmer survey based approach at both national community scales, with particular focus on identifying system actors, planting material management, exchange mechanisms, geographies, variety use, performed...
Child stunting in Vietnam has reduced substantially since the turn of century but remained relatively high for several years. We analysed data on children 6-59 months (n = 85,932) from Nutritional Surveillance System, a nationally representative cross-sectional survey. Multivariable Poisson regression models were used to estimate relative risk (RR) stunting, stratified by child age and ecological region. Covariates at child, maternal, household, environmental levels included based available...
The COVID-19 crisis is worsening food insecurity by undermining informal chains. We focus on impacts involving the chains that incorporate resilience-enhancing biodiversity of and agriculture known as agrobiodiversity. Our analysis addresses how agrobiodiversity are impacted policies interventions amidst disruptions. methodology relies research in Peru with a cites surrounding areas Lima, Arequipa, Cusco, Huancayo, Huánuco. extend these insights to similar challenges opportunities across...
Nutrition, food systems, and the biodiversity of agriculture (agrobiodiversity) are rapidly changing among indigenous smallholders in Andean countries, across Latin America, globally. Urgent calls for sovereignty recognize global transformations nutrition, agriculture, climate change amid geographically uneven development vulnerability to these shocks that recently include coronavirus/Covid-19 pandemic. Collaborating with a praxis-oriented institution focused on social nutrition public...
Andean communities in central Peru play a key role the conservation of vicuñas (Vicugna vicugna), protected species that depends on puna grass and flooded vegetation for food access to water throughout year. This study focuses seven Lucanas Ayacucho, dry mountainous region Peru, emphasizing need accurate information monitor resources context climate change support community decision-making. In this research, based Google Earth Engine (GEE), we evaluated performance classification...
Botanical species and morphological genetic diversity represent different yet linked units of conservation. These features, their spatial distribution in the central Peruvian Andean highlands Huancavelica, were used as a basis for characterizing quantifying potato agrobiodiversity at scales. Results show that individual farm households maintain high levels cultivar, morphological, diversity. At regional level, all cultivated species, with exception Solanum ajanhuiri, found to be present....
Biocultural diversity is central to the nutrition, resilience, and adaptive capacity of Indigenous traditional peoples, who collectively maintain longest ongoing human experiences with provision food under environmental change. In form crops livestock associated knowledge on their cultivation use, food-related biocultural likewise underpins global security. As system transformation increasingly recognized as an urgent priority, we argue that security, sustainability, can be furthered through...
