Seasonal rounds are deliberative articulations of a community’s sociocultural relations with their ecological system. The process of visualizing seasonal rounds informs transdisciplinary research. We present a methodological approach forcommunities of enquiryto engagecommunities of practicethrough context-specific sociocultural and ecological relations driven by seasonal change. We first discuss historical précis of the concept of seasonal rounds that we apply to assess the spatial and temporal communal migrations and then describe current international research among Indigenous and rural communities in North America and Central Asia by the creation of a common vocabulary through mutual respect for multiple ways of knowing, validation of co-generated knowledge, and insights into seasonal change. By investigating the relationship between specific biophysical indicators and livelihoods of local communities, we demonstrate that seasonal rounds are an inclusive and participatory methodology that brings together diverse Indigenous and rural voices to anticipate anthropogenic climate change.

Smallholders throughout sub-Saharan Africa produce legume crops as sources of food, fodder, and cash income, as well as to improve soil fertility. Ethiopian farmers have developed diverse legume varieties that enable adaptation to changing agroecological and sociocultural conditions. However, over the past several decades, as farm sizes declined and extension services promoted new varieties developed by plant breeders, changes in legume diversity have not been monitored. Based on interviews with smallholder farmers (n = 1296), we investigated the status of inter- and intraspecific legume diversity in major production areas of Ethiopia for five food legumes: common bean (Phaseolus vulgaris L.), field pea (Pisum sativum L.), faba bean (Vicia faba L.), groundnut (Arachis hypogaea L.) and fenugreek (Trigonella foenum-graecum L.). Legume species richness increased with altitude, relative household wealth, and land area planted to legumes. The highest numbers of varieties were found for common bean, followed by field pea, faba bean, groundnut and fenugreek. The average number of varieties planted per household was low (ranging from 1 to 2) and often much lower than the number reported in the same community or zone, which ranged from 2 to 18. For three out of the five species, the number of varieties significantly increased with total land area planted to legumes. Most varieties were rare, planted by less than 1/3 of farmers; however, informants accurately named varieties planted by others in the same community, demonstrating awareness of legume diversity at the community level. Given that the ability to plant multiple legume varieties is limited by land size, policies need to strengthen community-level conservation based on the diverse interests and needs of individual households.

Food sovereignty is understood as the right to determine food systems, and the ability to exercise this right requires the capacity to obtain, produce, and distribute culturally relevant foods. In the Standing Rock Nation of the northern Great Plains, efforts to reclaim food sovereignty include projects to increase the availability of gathered and gardened plants that are necessary components of traditional foods. Toward this objective, a voucher-based food assistance program administered by the Standing Rock Tribe is helping elders obtain culturally meaningful foods while contributing to the growth of farmers' markets within the reservation. As program enrollment and market attendance increase, organizers are considering the spatial arrangement of food system components and its influence on accessibility and participation. Our GIS spatial analysis of voucher issuance and redemption patterns reveals that the minimum cost-distance to market explains 33% of variance in voucher redemption. In order to improve program equity and efficiency, cost-distance models are used to identify potential additional market locations that would reduce the effort associated with trips to market and thus encourage participation. These analyses and possible spatial solutions contribute a powerful tool to improve food-system planning and to enhance the food sovereignty of indigenous communities in rural areas.

Indigenous food sovereignty relies on ecological knowledge of plants and animals, including knowledge related to their development and behavior through the seasons. In the context of anthropogenic climate change, ecological calendars based on Indigenous knowledge may enable communities to anticipate seasonal phenomena. We conducted research with communities in the Standing Rock Nation (North and South Dakota, USA) to develop ecological calendars based on their ecological knowledge. We present ecological calendars developed in seven communities through a series of workshops and interviews. These calendars are rich with knowledge about temporal relations within each community's ecosystem, including the use of plants and animals as seasonal indicators and cues for food system activities. However, the calendars also reveal the impacts of cultural genocide wrought by the United States government in its efforts to colonize the lands and minds of Indigenous communities. Given the diversity of knowledge among Standing Rock communities, we identify opportunities for knowledge exchange to revitalize ecological relations at the heart of food sovereignty. We highlight the potential for ecological calendars to facilitate climate adaptation by enabling communities to synchronize their food systems with an increasingly variable climate.

Field pea is grown by smallholder farmers in Ethiopia as a source of food, fodder, income, and soil fertility. This study explores intraspecific diversity of field pea and its contribution to farmers' livelihoods in two agroecological zones of South Tigray and South Wollo, northeastern Ethiopia. Interviews were conducted with 168 farming households. The number of varieties and the Shannon Diversity Index (SDI) were higher in South Tigray (seven varieties, 0.35 SDI) than South Wollo (two varieties, 0.025 SDI). Farmers in South Tigray plant field pea during two growing seasons, allowing for integration of multiple varieties into their farming systems. The price of one field pea type from South Tigray known as “dekoko” was twice as high as other field pea varieties, most likely due to high demand and relatively low supply. Key informants reported “dekoko” has become less common in their communities, with diseases and pests reported as major production constraints. Multistakeholder collaboration is recommended to enhance the contribution of field pea to Ethiopian farming systems.
