Varieties, seed systems, and experimentation
This paper explores farmers’ preferences and practices in relation to rice variety selection and management, and reports on a step-by-step experimentation with varieties in southern Guinea-Bissau. We used a mixed-methods and transdisciplinary approach from 2021–2023 to better understand why the poor uptake of formally introduced varieties persists despite a long track of research and interventions in the mangrove swamp rice (MSR) agroecosystem. W…
Cross-scale chronological analysis of Southeast Asia's seed regulations and emerging challenges for seed commons
Seed regulatory frameworks paradoxically often attempt to increase farmers' access to quality seed via restrictions on their production and exchange. Efforts to balance regulatory objectives lead to tensions between the legal situation of ‘informal’ and ‘formal’ seed systems. This is especially true for vegetatively propagated crops with decentralized, farmer-dominated seed systems. In Southeast Asia, cassava (Manihot esculenta) exemplifies an ec…
Analysis of Endogenous Strategies to Establish Rice Crops in Mangrove Swamp Fields
We documented and analyzed endogenous farmers’ knowledge and practices regarding sowing methods in mangrove swamp rice (MSR) farming in Southern Guinea-Bissau. Although many external interventions in MSR farming have occurred since colonial times, little is known about which techniques farmers use, and why, and when they establish their crops. To address this knowledge gap, we used a mixed-methods, transdisciplinary approach that combined technog…
Climate adaptive rice planting strategies diverge across environmental gradients in the Indo-Gangetic Plains
The timing of rice planting has a profound influence on the productivity of the rice-wheat cropping pattern in the Indo-Gangetic Plains (IGP), a system that provides the foundation for food security in South Asia. Nevertheless, strategies for adaptive rice planting in a rapidly changing climate are not well established. In this ex-ante analysis, regional gridded crop model simulations are deployed to investigate the impact of different rice plant…
Restore politics in societal debates on new genomic techniques
End of April 2021, the European Commission published its study on New Genomic Techniques (NGTs). The study involved a consultation of Member States and stakeholders. This study reveals a split on whether current legislation should be maintained or adapted to take account of scientific progress and the risk level of NGT products. This split was predictable. New technological developments challenge both ethical viewpoints and regulatory institution…
The role of ICT in collective management of public bads
What is the role of Information and Communication Technology in the collective management of public bads? We study epidemics of late blight in potato as a collective action challenge in Oromia, Ethiopia. As a highly infectious, air-borne disease, potato late blight represents a public bad: it is non-excludable and non-rival. Managing public bads is a major policy challenge in Ethiopia due to structural inefficiencies and resource constraints to f…
Combining experiential and social learning approaches for crop disease management in a smallholder context
Effective management of crop diseases is a key precondition for sustainable crop production and to improve food security globally. However, learning approaches that improve smallholder farmers’ knowledge, perceptions, and practices to deal with crop diseases by fostering social and technical innovations are seldom studied. A study was conducted to examine: (1) how a combination of experiential and social learning approaches influences potato farm…
Collective Production and Marketing of Quality Potato Seed
In spite of many initiatives to set up community or farmer-group-based seed production, there is little empirical evidence about the group functioning in producing and marketing quality seed. This article therefore aims to contribute to better understanding of the process and practice of seed potato cooperatives’ formation and operation in Chencha, Ethiopia. Our study specifically focused on why and how farmer groups organize, produce and market …
Perspectives of Children Orphaned by HIV/Aids on Ecology and Gathering of Wild Orchids in Tanzania
Orchid gathering in the Southern Highlands of Tanzania became an income generating strategy for HIV/AIDS-affected households, particularly for children orphaned by HIV/AIDS. Being orphaned might have implications for children's local ecological knowledge leading to indiscriminate harvesting of both preferred and non-preferred orchids. Using qualitative and quantitative mixed methods, we assessed the knowledge of wild orchid species among gatherer…
Challenging Current Knowledge on Amazonian Dark Earths
Amazonian indigenous people grow manioc in landscapes of different agricultural potential, yet studies on indigenous manioc production on fertile soils are scarce. Non-indigenous communities grow specific manioc landraces on fertile Amazonian Dark Earths (ADE), but it is unknown whether indigenous farmers also do so. During 2 years, we studied manioc cultivation by five indigenous groups on different Amazonian soils using quantitative and qualita…
Classification and Use of Natural and Anthropogenic Soils by Indigenous Communities of the Upper Amazon Region of Colombia
Outsiders often oversimplify Amazon soil use by assuming that abundantly available natural soils are poorly suited to agriculture and that sporadic anthropogenic soils are agriculturally productive. Local perceptions about the potentials and limitations of soils probably differ, but information on these perceptions is scarce. We therefore examined how four indigenous communities in the Middle Caquetá River region in the Colombian Amazon classify …

Spatial and Seasonal Diversity of Wild Food Plants in Home Gardens of Northeast Thailand1
Wild food plants (WFPs) are major components of tropical home gardens, constituting an important resource for poor farmers. The spatial and seasonal diversity of WFPs was analyzed across multi-species spatial configurations occurring within home gardens in a rice farming village in northeast Thailand. Data were collected in 77 sampling sites corresponding to five different home garden spatial configurations, namely fenced plot, fenced plot margin…
Increasing homogeneity in global food supplies and the implications for food security
Significance This study provides evidence of change in the relative importance of different crop plants in national food supplies worldwide over the past 50 years. Within a global trend of increased overall quantities of food calories, protein, fat, and weight, and increased proportions of those quantities sourcing from energy-dense foods, national food supplies diversified in regard to contributing measured crop commodities. As a consequence, na…

HIV and Severity of Seasonal Household Food-Related Coping Behaviors in Rural Ghana
In-depth research was conducted to evaluate the seasonal food insecurity of HIV-positive and HIV-negative farm households in the Eastern Region, Ghana. A Coping Strategy Index (CSI) was used to assess household food-related coping behaviors. HIV-positive farm households often relied on both less severe and more severe coping behaviors, had a higher CSI, cultivated a smaller field area, harvested fewer food species from farms and gardens, and obta…
Assessing the levels of food shortage using the traffic light metaphor by analyzing the gathering and consumption of wild food plants, crop parts and crop residues in Konso, Ethiopia
Background Humanitarian relief agencies use scales to assess levels of critical food shortage to efficiently target and allocate food to the neediest. These scales are often labor-intensive. A lesser used approach is assessing gathering and consumption of wild food plants. This gathering per se is not a reliable signal of emerging food stress. However, the gathering and consumption of some specific plant species could be considered markers of foo…
