Abstract Smallholder farmers are some of the poorest and most food insecure people on Earth. Their high nutritional and economic reliance on home‐grown produce makes them particularly vulnerable to environmental stressors such as pollinator loss or climate change which threaten agricultural productivity. Improving smallholder agriculture in a way that is environmentally sustainable and resilient to climate change is a key challenge of the 21st century.Ecological intensification, whereby ecosystem services are managed to increase agricultural productivity, is a promising solution for smallholders. However, smallholder farms are complex socio‐ecological systems with a range of social, ecological and environmental factors interacting to influence ecosystem service provisioning. To truly understand the functioning of a smallholder farm and identify the most effective management options to support household food and nutrition security, a holistic, systems‐based understanding is required.In this paper, we propose a network approach to understand, visualise and model the complex interactions occurring among wild species, crops and people on smallholder farms. Specifically, we demonstrate how networks may be used to (a) identify wild species with a key role in supporting, delivering or increasing the resilience of an ecosystem service; (b) quantify the value of an ecosystem service in a way that is relevant to the food and nutrition security of smallholders; and (c) understand the social interactions that influence the management of shared ecosystem services.Using a case study based on data from rural Nepal, we demonstrate how this framework can be used to connect wild plants, pollinators and crops to key nutrients consumed by humans. This allows us to quantify the nutritional value of an ecosystem service and identify the wild plants and pollinators involved in its provision, as well as providing a framework to predict the effects of environmental change on human nutrition.Our framework identifies mechanistic links between ecosystem services and the nutrients consumed by smallholder farmers and highlights social factors that may influence the management of these services. Applying this framework to smallholder farms in a range of socio‐ecological contexts may provide new, sustainable and equitable solutions to smallholder food and nutrition security.

Understanding How Smallholders Integrated into Pericoupled and Telecoupled Systems
Increasing connections and influences from near to far have changed social structures, access to natural resources, and essential livelihoods of smallholders (i.e., those with incomes generated primarily from natural resources on small rural properties). However, the potential benefits and negative impacts from these connections to smallholders’ livelihoods and social-ecological effects remain understudied. In this paper, we applied the frameworks of pericoupling and telecoupling (human-nature interactions between adjacent and distant systems, respectively) to systematically investigate how the flows linking smallholder systems to other systems affect their livelihoods, and causing varying economic, social, and environmental effects from case to case. We synthesized 12 cases of smallholder systems around the world that are linked to adjacent and distant systems through flows of goods, people, resources, and/or information. In each case, we summarized smallholders’ agency, i.e., capability on the formation or operation of these flows, and the changes on livelihoods on the economic, social, and environment effects. Results suggest that strong smallholder agency is associated more with positive than negative effects. Smallholders with medium to high agency have greater overall well-being within the area of interest. Smallholders integrated in pericoupled systems often have strong agency. Being spillover systems in an intercoupled system (e.g., large-scale agricultural investments) can often cause negative outcomes unless smallholders have additional pericoupling flows. Our findings suggest one potential approach to ending poverty and increasing well-being for smallholders is creating and increasing pericoupling flows to empower smallholders for desired livelihood and social-ecological outcomes.

Human health and livelihoods are threatened by declining marine fisheries catches, causing substantial interest in the sources and dynamics of fishing. Catch analyses in individual exclusive economic zones (EEZs) and the high seas are abundant, and research across multiple EEZs is growing. However, no previous studies have systematically compared catches, intranational versus international fish flows, and fishing nations within all of the world’s EEZs and across adjacent and distant EEZs and the high seas to inform “metacoupled” fisheries management. We use the metacoupling framework—a new approach for evaluating human–nature interactions within and across adjacent and distant systems (metacouplings)—to illustrate how fisheries catches were locally, regionally, and globally interconnected in 1950–2014, totaling 5.8 billion metric tons and increasing by 298% (tonnage) and 431% (monetary value) over this time period. Catches by nations in their own EEZs (largest in Peru) and adjacent EEZs (largest in Indonesia) constituted 86% of worldwide catches, growing in 1950–1996 but declining in 1997–2014. In contrast, catches in distant EEZs and the high seas—largest in Morocco, Mauritania, and Canada—peaked in 1973 and have since represented 9–21% of annual catches. Our 65-year, local–regional–global analysis illustrates how metacoupled fisheries governance—holistic management of multiscalar catches, flows, and tradeoffs within and among fisheries—can improve food and nutrition security, livelihood resilience, and biodiversity conservation across the world.more » « less

Coastal ecosystems and human communities are threatened worldwide by climate change, and shocks from social, market and political change. There is an urgent global need to promote resilient food production and livelihoods in the face of these shocks. Small-scale fisheries (SSF) in rural settings can be particularly vulnerable as they frequently lack the resources, rights and infrastructure to respond to shocks originating outside the focal systems. We examined ecological and social outcomes of environmental extremes in a SSF socio-ecological system (SES) by using long-term oceanographic (between 2010-2019) and ecological (2006-2018) data tracking change in a kelp forest ecosystem of Baja California, Mexico, and concurrent documentation of proactive and reactive actions of a fishing community organized in a cooperative. Results indicate a complex landscape of ‘winners’ and ‘losers’ among species and fisheries exposed to unprecedented environmental extremes, including marine heat waves and prolonged hypoxia, and a suite of adaptive actions by the local fishing cooperative, and others in the region, that have helped confront these rapid and drastic changes. Cooperatives have established voluntary marine reserves to promote recovery of affected populations and have invested in diversification of activities enabled by access rights, collective decision-making, and participatory science programs. Results indicate that local actions can support social and ecological resilience in the face of shocks, and that enabling locally-driven adaptation pathways is critical to resilience. This case study highlights the crucial importance of strengthening and supporting rights, governance, capacity, flexibility, learning, and agency for coastal communities to respond to change and sustain their livelihoods and ecosystems in the long run.more » « less

Abstract Human–environment interactions within and across borders are now more influential than ever, posing unprecedented sustainability challenges. The framework of metacoupling (interactions within and across adjacent and distant coupled human–environment systems) provides a useful tool to evaluate them at diverse temporal and spatial scales. While most metacoupling studies have so far addressed the impacts of distant interactions (telecouplings), few have addressed the complementary and interdependent effects of the interactions within coupled systems (intracouplings) and between adjacent systems (pericouplings). Using the production and trade of a major commodity (soybean) as a demonstration, this paper empirically evaluates the complex effects on deforestation and economic growth across a globally important soybean producing region (Mato Grosso in Brazil). Although this region is influenced by a strong telecoupling process (i.e., soybean trade with national and international markets), intracouplings pose significant effects on deforestation and economic growth within focal municipalities. Furthermore, it generates pericoupling effects (e.g., deforestation) on adjacent municipalities, which precede economic benefits on adjacent systems, and may occur during and after the soybean production takes place. These results show that while economic benefits of the production of agricultural commodities for global markets tend to be localized, their environmental costs tend to be spatially widespread. As deforestation also occurred in adjacent areas beyond focal areas with economic development, this study has significant implications for sustainability in an increasingly metacoupled world.more » « less

null (Ed.)Rural life in México has changed drastically over the past several decades in the wake of structural reforms in the 1980s and the North American Free Trade Agreement (NAFTA) implemented in 1994. Researchers predicted dire consequences for smallholder farmers following trade liberalization and in certain respects the prophecies have been fulfilled. Indeed, many regions experienced significant out-migration as smallholders, unable to compete with global maize imports without price subsidies, sold or abandoned their lands, making way for the expansion of industrial agriculture into forests, secondary vegetation and primary crops. Nevertheless, many smallholders have adapted to the new economic environment with farming systems that manage risk by diversifying portfolios to incorporate commercialized maize and livestock production. This article examines the evolution of smallholder farming systems since the mid 1980s, when the impact of neoliberal reforms emerged, using data collected from field research on 130 smallholder farms in the Pátzcuaro Lake Watershed (PLW) in the State of Michoacán. Farmers in the PLW have been characterized as traditional peasant farmers, planting crops for subsistence, including a diverse array of domestic maize varieties and practicing limited animal husbandry with chickens, turkeys, pigs, an oxen and a cow or two for milk. But the results presented in this article show that the traditional peasant farming systems in the region have changed substantially to a highly diversified agriculture-cattle-forest system. Most notable changes include the use of fertilizers and pesticides; and the increase in livestock herd and reorientation to beef production. The results demonstrate the resilience of smallholder farmers, while at the same time raising potential concern that increased reliance on livestock and beef production specialization, might lead to shifts in farming systems that replace domestic maize varieties with hybrid corn used primarily for animal feed and thereby leaving vulnerable the genetic reservoir of traditional maize landraces.more » « less
