- Agricultural land abandonment (ALA) is widespread in many countries of the global north. It impacts rural communities, traditional landscapes, biodiversity and ecosystem services. It is an opportunity for ecosystem restoration or new landscape functions. We explored ALA in study areas in Australia, Portugal and Sweden. In each, we assessed plant species diversity, historical trajectories of land cover change; and the socioeconomic past, present and future in interviews with farmers. The ALA data was integrated and analysed by identifying the drivers of change. The relative importance of each driver and its scale of action was estimated, both in the past (1950-2010) and in the future (2010-2030). ALA has transformed rural landscapes in the study areas of Portugal and Sweden. It is at a much earlier stage with potential to increase in the Australian case. We identified a set of driving forces, classified into pressures, frictions and attractors that clarify why ALA, noting its temporal and spatial scale, occurs differently in each study area. The effect of the drivers is related to social and historical contexts. Pressures and attractors encouraging agricultural abandonment are strongest in Portugal and Sweden. Generally more (institutionalized) frictions are in place in these European sites, intended to prevent further change, based on the benefits assumed for biodiversity and aesthetics. In Australia, the stimulation of driving forces to promote a well-managed abandonment of some cleared areas could be highly beneficial for biodiversity, minimally disruptive for current dairy farming operations and would bring opportunities for alternative types of rural development.

Bokkapitel (refereegranskat)abstract
- Bringing together theoretical and empirical research from 22 countries in Europe, North America, Australia, South America and Japan, this book offers a state-of-the-art survey of conceptual and methodological research and planning issues relating to landscape, heritage, and development. It has 30 chapters grouped in four main thematic sections: landscapes as a constitutive dimension of territorial identities; landscape history and landscape heritage; landscapes as development assets and resources; and landscape research and development planning. The contributors are scholars from a wide range of cultural and professional backgrounds, experienced in fundamental and applied research, planning and policy design. They were invited by the co-editors to write chapters for this book on the basis of the theoretical frameworks, case-study research findings and related policy concerns they presented at the 23rd Session of PECSRL - The Permanent European Conference for the Study of the Rural Landscape, organized by TERCUD - Territory, Culture and Development Research Centre, Universidade Lusofona, in Lisbon and Obidos, Portugal, 1 - 5 September 2008. With such broad inter-disciplinary relevance and international scope, this book provides a valuable overview, highlighting recent findings and interpretations on historical, current and prospective linkages between changing landscapes and natural, economic, cultural and other identity features of places and regions; landscape-related identities as local and regional development assets and resources in the era of globalized economy and culture; the role of landscape history and heritage as platforms of landscape research and management in European contexts, including the implementation of The European Landscape Convention; and, the strengthening of the landscape perspective as a constitutive element of sustainable development.

Tidskriftsartikel (refereegranskat)abstract
- The United Nations Decade of Ocean Science for Sustainable Development 2021-2030 (the 'Ocean Decade') is poised to stimulate new cooperation for ocean science, but makes no mention of conflict or peace. We contend that this is a missed opportunity, and use an environmental peacebuilding typology to review how ocean science has historically contributed to peace. Such considerations are timely in the context of an increasingly complex and multidimensional ocean risk landscape, due among other things to unprecedented growth in the extent and intensity of ocean uses, and increasing conflict potential as the ocean becomes a more crowded and coveted place. We conclude by proposing the Ocean Decade Implementation Plan be appended to include an eighth intended outcome: 'A Peaceful Ocean'.

Ecosystem service mapping needs to capture more effectively the biodiversity important for service supply
- 2021
-
Ingår i: Ecosystem Services. - : Elsevier BV. - 2212-0416 .- 2212-0416. ; 48
-
Tidskriftsartikel (refereegranskat)abstract
- Large scale mapping of ecosystem services and functions (ES) is an important tool for researchers and policy makers to inform nature management and policies but it relies mainly on ES modelled with biophysical data such as land cover, henceforth biophysical ES. Other ES, henceforth species-based ES, are modelled at small scales based on species providers. As species-based ES are rarely included in multi-service, large-scale spatial assessments, we do not know if these assessments provide accurate information for managing the biodiversity important for species-based ES. We calculate and map weighted provider richness (WPR) for 9 species-based ES by weighting species data in Europe by their functional efficiency derived from functional trait databases. We compare WPR spatial patterns with those of 9 biophysical ES at continental and national scales in Europe. We find positive correlations at continental scale, and weaker positive correlations or neutral relationships at national scale between biophysical ES and WPR. Patterns of synergies and trade-offs for WPR are different from those of biophysical ES and change from continental to national scale. WPR for most species-based ES are synergistic with each other but WPR for existence value has the weakest synergies with other WPRs. Biodiversity data is still insufficient to truly map species-based ES at large scales but WPR can represent the next step forward for spatial ES assessments. A lack of spatial information on species-based ES in large-scale assessments leads to inaccurate information on ES distribution, and their synergies and trade-offs, which can lead to misguided management and conservation decisions.

Advancing sustainability through mainstreaming a social–ecological systems perspective

- The concept of social-ecological systems is useful for understanding the interlinked dynamics of environmental and societal change. The concept has helped facilitate: (1) increased recognition of the dependence of humanity on ecosystems; (2) improved collaboration across disciplines, and between science and society; (3) increased methodological pluralism leading to improved systems understanding; and (4) major policy frameworks considering social-ecological interactions. Despite these advances, the potential of a social-ecological systems perspective to improve sustainability outcomes has not been fully realized. Key priorities are to: (1) better understand and govern social-ecological interactions between regions; (2) pay greater attention to long-term drivers; (3) better understand the interactions among power relations, justice, and ecosystem stewardship; and (4) develop a stronger science-society interface.

A brighter future : Complementary goals of diversity and multifunctionality to build resilient agricultural landscapes
- 2020
-
Ingår i: Global Food Security. - : Elsevier BV. - 2211-9124. ; 26
-
Tidskriftsartikel (refereegranskat)abstract
- Humanity places a heavy burden on agricultural landscapes, demanding plentiful food, multiple ecosystem functions, and biodiversity conservation. We quantified areas growing ‘brighter’ and ‘darker’ (i.e., better or worse than expected based on extrinsic constraints) for multifunctionality of ecosystem services (ES) over time across a dynamic agricultural landscape. To explore how areas changing in ES multifunctionality, we likewise explored temporal changes in additional features of resilience in social-ecological systems, including: (1) species functional richness and dispersion, (2) agrodiversity, (3) the diversity of farm characteristics and human demographics in the area, and (4) landscape structure and diversity. We found areas increasing in multifunctionality were likewise becoming more biologically and agriculturally diverse, without large losses in overall food production. This suggests the potential for complementarity among goals of food production, multiple ES, and biological and agricultural diversity for agricultural landscapes. While we cannot distinguish whether diversity is the driver, or the consequence, of ES multifunctionality, we can conclude that building diverse, multifunctional agricultural landscapes are an important goal for general system resilience and the future of food security.

Rewiring food systems to enhance human health and biosphere stewardship
- 2017
-
Ingår i: Environmental Research Letters. - : IOP Publishing. - 1748-9326. ; 12:10
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Food lies at the heart of both health and sustainability challenges. We use a social-ecological framework to illustrate how major changes to the volume, nutrition and safety of food systems between 1961 and today impact health and sustainability. These changes have almost halved undernutrition while doubling the proportion who are overweight. They have also resulted in reduced resilience of the biosphere, pushing four out of six analysed planetary boundaries across the safe operating space of the biosphere. Our analysis further illustrates that consumers and producers have become more distant from one another, with substantial power consolidated within a small group of key actors. Solutions include a shift from a volume-focused production system to focus on quality, nutrition, resource use efficiency, and reduced antimicrobial use. To achieve this, we need to rewire food systems in ways that enhance transparency between producers and consumers, mobilize key actors to become biosphere stewards, and re-connect people to the biosphere.

Interplay of trade and food system resilience : Gains on supply diversity over time at the cost of trade independency
- 2020
-
Ingår i: Global food security. - : Elsevier BV. - 2211-9124. ; 24
-
Tidskriftsartikel (refereegranskat)abstract
- Rapidly increasing international food trade has drastically altered the global food system over the past decades. Using national scale indicators, we assess two of the resilience principles that directly reflect the effects of global trade on food systems - namely, maintaining diversity and redundancy, and managing connectivity. We perform our analysis for four nutritional components: dietary energy, proteins, fat, and quantity of vegetables & fruits the key pillars of the WHO dietary recommendations. Our results indicate that, between 1987 and 2013, food supply diversity increased significantly for most of the world's population at the cost of an elevated dependency upon food imports. Food production diversity, particularly in terms of dietary energy and vegetables & fruits, increased for a large proportion of the world population, with the exception being major exporting countries, where it decreased. Of particular note is our finding that, despite a growing number of people being heavily dependent upon imports, the number of import partners decreased more often than it increased, except for the case of vegetables & fruits. This combination of increased dependency on imports and a reduced number of import partners indicates a potential vulnerability to disruptions in linked food systems. Additionally, it is alarming that we found many countries where the studied resilience aspects systematically declined, elevating their exposure to future shocks in the food system.

Land-use intensification reduces functional redundancy and response diversity in plant communities
- 2010

Ingår i: Ecology Letters. - : Wiley. - 1461-023X .- 1461-0248. ; 13:1, s. 76-86
-
Tidskriftsartikel (refereegranskat)abstract
- Ecosystem resilience depends on functional redundancy (the number of species contributing similarly to an ecosystem function) and response diversity (how functionally similar species respond differently to disturbance). Here, we explore how land-use change impacts these attributes in plant communities, using data from 18 land-use intensity gradients that represent five biomes and > 2800 species. We identify functional groups using multivariate analysis of plant traits which influence ecosystem processes. Functional redundancy is calculated as the species richness within each group, and response diversity as the multivariate within-group dispersion in response trait space, using traits that influence responses to disturbances. Meta-analysis across all datasets showed that land-use intensification significantly reduced both functional redundancy and response diversity, although specific relationships varied considerably among the different land-use gradients. These results indicate that intensified management of ecosystems for resource extraction can increase their vulnerability to future disturbances. Ecology Letters (2010) 13: 76-86.

- The ecosystem service concept is recognized as a useful tool to support sustainability in decision-making. In this study, we collaborated with actors in the Helge a catchment, southern Sweden, in an iterative participatory ecosystem service assessment. Through workshops and interviews, we jointly decided which ecosystem services to assess and indicators to use in order to achieve a sense of ownership and a higher legitimacy of the assessment. Subsequently, we explored the landscape-level interactions between the 15 assessed services, and found that the area can be described using three distinct ecosystem service bundles. The iterative, participatory process strengthened our analysis and created a shared understanding and overview of the multifunctional landscape around Helge a among participants. Importantly, this allowed for the generated knowledge to impact local strategic sustainability planning. With this study, we illustrate how similar processes can support local decision-making for a more sustainable future.

Elevating the role of water resilience in food system dialogues
- 2022
-
Ingår i: Water Security. - : Elsevier B.V.. - 2468-3124. ; 17
-
Tidskriftsartikel (refereegranskat)abstract
- Ensuring resilient food systems and sustainable healthy diets for all requires much higher water use, however, water resources are finite, geographically dispersed, volatile under climate change, and required for other vital functions including ecosystems and the services they provide. Good governance for resilient water resources is a necessary precursor to deciding on solutions, sourcing finance, and delivering infrastructure. Six attributes that together provide a foundation for good governance to reduce future water risks to food systems are proposed. These attributes dovetail in their dual focus on incorporating adaptive learning and new knowledge, and adopting the types of governance systems required for water resilient food systems. The attributes are also founded in the need to greater recognise the role natural, healthy ecosystems play in food systems. The attributes are listed below and are grounded in scientific evidence and the diverse collective experience and expertise of stakeholders working across the science-policy interface: Adopting interconnected systems thinking that embraces the complexity of how we produce, distribute, and add value to food including harnessing the experience and expertise of stakeholders s; adopting multi-level inclusive governance and supporting inclusive participation; enabling continual innovation, new knowledge and learning, and information dissemination; incorporating diversity and redundancy for resilience to shocks; ensuring system preparedness to shocks; and planning for the long term. This will require food and water systems to pro-actively work together toward a socially and environmentally just space that considers the water and food needs of people, the ecosystems that underpin our food systems, and broader energy and equity concerns.

DIFFERENCES IN FOREST PLANT FUNCTIONAL TRAIT DISTRIBUTIONS ACROSS LAND-USE AND PRODUCTIVITY GRADIENTS
- 2013
-
Ingår i: American Journal of Botany. - : Wiley. - 0002-9122 .- 1537-2197. ; 100:7, s. 1356-1368
-
Tidskriftsartikel (refereegranskat)abstract
- Premise of study: Plant functional traits are commonly used as proxies for plant responses to environmental challenges, yet few studies have explored how functional trait distributions differ across gradients of land-use change. By comparing trait distributions in intact forests with those across land-use change gradients, we can improve our understanding of the ways land-use change alters the diversity and functioning of plant communities. Methods: We examined how the variation and distribution of trait values for seven plant functional traits differ between reference natural forest and three types of land-use conversion (pasture, old-field, or legacy sites-regrowth following logging), landscape productivity (NPP) and vegetation strata (tree or non-tree understory), in a meta-analysis of studies from 15 landscapes across five continents. Key results: Although trait variation often differed between land-uses within a landscape, these patterns were rarely consistent across landscapes. The variance and distribution of traits were more likely to differ consistently between natural forest and land-use conversion categories for understory (non-tree) plants than for trees. Landscape productivity did not significantly alter the difference in trait variance between natural forest and land-use conversion categories for any trait except dispersal. Conclusions: Our results suggest that even for traits well linked to plant environmental response strategies, broad classes of land-use change and landscape productivity are not generally useful indicators of the mechanisms driving compositional changes in human-modified forest systems.

- Social-ecological interactions have been shown to generate interrelated and reoccurring sets of ecosystem services, also known as ecosystem service bundles. Given the potential utility of the bundles concept, along with the recent surge in interest it is timely to reflect on the concept, its current use and potential for the future. Based on our ecosystem service bundle experience, expertise, and ecosystem service bundle analyses, we have found critical elements for advancing the utility of ecosystem service bundle concept and deepening its impact in the future. In this paper we 1) examine the different conceptualizations of the ecosystem service bundle concept; 2) show the range of benefits of using a bundles approach; 3) explore key issues for improving research on ecosystem service bundles, including indicators, scale, and drivers and relationships between ecosystem services; and 4) outline priorities for the future by facilitating comparisons of ecosystem service bundle research.

Social-ecological drivers of multiple ecosystem services : what variables explain patterns of ecosystem services across the Norrstrom drainage basin?
- 2016
-
Ingår i: Ecology and Society. - 1708-3087. ; 21:1
-
Tidskriftsartikel (refereegranskat)abstract
- In human dominated landscapes many diverse, and often antagonistic, human activities are intentionally and inadvertently determining the supply of various ecosystem services. Understanding how different social and ecological factors shape the availability of ecosystem services is essential for fair and effective policy and management. In this paper, we evaluate how well alternative social-ecological models of human impact on ecosystems explain patterns of 16 ecosystem services (ES) across the 62 municipalities of the Norrstrom drainage basin in Sweden. We test four models of human impact on ecosystems, land use, ecological modernization, ecological footprint, and location theory, and test their ability to predict both individual ES and bundles of ES. We find that different models do best to predict different types of individual ES. Land use is the best model for predicting provisioning services, standing water quality, biodiversity appreciation, and cross-country skiing, while other models work better for the remaining services. However, this range of models is not able to predict some of the cultural ES. ES bundles are predicted worse than individual ES by these models, but provide a clear picture of variation in multiple ecosystem services based on limited information. Based on our results, we offer suggestions on how social-ecological modeling and assessments of ecosystems can be further developed.

Land-use intensity mediates ecosystem service tradeoffs across regional social-ecological systems
- 2021
-
Ingår i: Ecosystems and People. - : Informa UK Limited. - 2639-5908 .- 2639-5916. ; 17:1, s. 264-278
-
Tidskriftsartikel (refereegranskat)abstract
- A key sustainability challenge in human-dominated landscapes is how to reconcile competing demands such as food production, water quality, climate regulation, and ecological amenities. Prior research has documented how efforts to prioritize desirable ecosystem services such as food and fiber have often led to tradeoffs with other services. However, the growing literature has revealed different and sometimes contradictory patterns in ecosystem service relationships. It thus remains unclear whether there are generalizable patterns across social-ecological systems, and if not, what factors explain the variations. In this study, we synthesize datasets of five ecosystem services from four social-ecological systems. We ask: (1) Are ecosystem service relationships consistent across distinct regional social-ecological systems? (2) How do ecosystem service relationships vary with land-use intensity at the landscape scale? (3) In case of ecosystem service tradeoffs, how does land-use intensity affect intersection points of tradeoffs along the landscape composition gradient? Our results reveal that land-use intensity increases magnitude of ecosystem service tradeoffs (e.g. food production vs. climate regulation and water quality) across landscapes. Land-use intensity also alters where provisioning and regulating services intersect: in high-intensity systems, food production and regulating services can be both sustained only at smaller proportions of agricultural lands, whereas in low-intensity systems, these services could be both supplied with greater proportions of agricultural lands. Our research demonstrates importance of considering multiple aspects of land uses (landscape composition and land-use intensity), and provides a more nuanced understanding and framework to enhance our ability to predict how land use alters ecosystem service relationships.

Forskningsöversikt (refereegranskat)abstract
- Farmland abandonment is changing rural landscapes worldwide, but its impacts on biodiversity are still being debated in the scientific literature. While some researchers see it as a threat to biodiversity, others view it as an opportunity for habitat regeneration. We reviewed 276 published studies describing various effects of farmland abandonment on biodiversity and found that a study's geographic region, selected metrics, assessed taxa, and conservation focus significantly affected how those impacts were reported. Countries in Eurasia and the New World reported mainly negative and positive effects of farmland abandonment on biodiversity, respectively. Notably, contrasting impacts were recorded in different agricultural regions of the world that were otherwise similar in land-use and biodiversity characteristics. We showed that the conservation focus (pre- or post-abandonment) in different regions is an important factor influencing how scientists address the abandonment issue, and this may affect how land-use policies are defined in agricultural landscapes.

Managing for biodiversity and ecosystem services in a context of farmland abandonment
- 2013
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In agricultural landscapes around the world, intensification of production and land abandonment are the two main trends impacting biodiversity and ecosystem services. Intensified agriculture is mostly seen as negative for biodiversity but effects of abandonment are controversial among scientists and practitioners. While abandonment can be detrimental to biodiversity in non-intensive farming systems, it can also provide an opportunity for regeneration of natural habitats. This thesis examines effects of different management options on biodiversity along an abandonment gradient from farmland to forest. It combines insights from a local case study in NW Portugal with an inter-regional meta-analysis on the effects of land-use change on response diversity, and a global meta-analysis on how impacts of abandonment on biodiversity are reported in scientific studies. Effects of abandonment were assessed for species richness and functional diversity for multiple taxa, and for the provision of multiple ecosystem services.At the global scale, abandonment impacts on biodiversity were reported in contrasting ways across world regions, and this was influenced by conservation views focused on pre vs. post abandonment conditions. In the study area, intermediate farming intensity, compared to abandoned forest habitats, generated higher plant richness at small scales and when post-abandonment forest was highly fragmented. In contrast, at larger scales, both farmland and forest had high species and functional diversity of plants and birds, while moths were more diverse in forests. All land uses provided multiple ecosystem services, but while provisioning services were highest in farmland, forests benefited regulating services, a difference not reflected in species richness distribution. In contrast to current European policies, abandonment was not found to be disadvantageous to biodiversity, except for species richness at very small scales. Thus, both farming and post-abandonment succession can generate high value ecosystems. In order to sustainably manage abandoned lands, farmland abandonment needs to be analyzed in a broader perspective, combining different types of indicators, from species to ecosystem services, and avoiding pre-conceived ideas on conservation, not always beneficial to the sustainable management of these landscapes.

- Ecosystem services (ES) is a valuable concept to be used in the planning and management of social-ecological landscapes. However, the understanding of the determinant factors affecting the interaction between services in the form of synergies or trade-offs is still limited. We assessed the production of 16 ES across 62 municipalities in the Norrstrom drainage basin in Sweden. We combined GIS data with publically available information for quantifying and mapping the distribution of services. Additionally, we calculated the diversity of ES for each municipality and used correlations and k-means clustering analyses to assess the existence of ES bundles. We found five distinct types of bundles of ES spatially agglomerated in the landscape that could be explained by regional social and ecological gradients. Human-dominated landscapes were highly multifunctional in our study area and urban densely populated areas were hotspots of cultural services.

Biodiversity, peace and conflict : understanding the connections
- 2024

Ingår i: Current Opinion in Environmental Sustainability. - 1877-3435 .- 1877-3443. ; 68
-
Tidskriftsartikel (refereegranskat)abstract
- Trajectories of human conflict have direct and indirect impacts on biodiversity and ecosystem function. These occur across terrestrial, marine and freshwater systems via the well-established drivers of biodiversity loss: land and sea-use change, climate change, overexploitation, pollution and invasive species. However, the mechanisms underlying the nature of some of these connections are still poorly explored, as is the compilation of existing evidence. Furthermore, indirect drivers, spillover effects, and synergistic relationships between drivers are additional knowledge gaps. Building a full picture requires exploring the magnitude and directionality of impacts within the wider context of socioeconomic change and geopolitics with which conflict is associated. As this knowledge advances, conflict in its diverse forms is likely to emerge as the most overlooked and significant indirect driver of biodiversity loss internationally. Additionally, it is our greatest challenge in achieving sustainable development, specifically due to the primacy of its influence on all other sustainability challenges.

Tidskriftsartikel (refereegranskat)abstract
- Although it is generally recognized that global biodiversity is declining, few studies have examined long-term changes in multiple biodiversity dimensions simultaneously. In this study, we quantified and compared temporal changes in the abundance, taxonomic diversity, functional diversity, and phylogenetic diversity of bird assemblages, using roadside monitoring data of the North American Breeding Bird Survey from 1971 to 2010. We calculated 12 abundance and diversity metrics based on 5-year average abundances of 519 species for each of 768 monitoring routes. We did this for all bird species together as well as for four subgroups based on breeding habitat affinity (grassland, woodland, wetland, and shrubland breeders). The majority of the biodiversity metrics increased or remained constant over the study period, whereas the overall abundance of birds showed a pronounced decrease, primarily driven by declines of the most abundant species. These results highlight how stable or even increasing metrics of taxonomic, functional, or phylogenetic diversity may occur in parallel with substantial losses of individuals. We further found that patterns of change differed among the species subgroups, with both abundance and diversity increasing for woodland birds and decreasing for grassland breeders. The contrasting changes between abundance and diversity and among the breeding habitat groups underscore the relevance of a multifaceted approach to measuring biodiversity change. Our findings further stress the importance of monitoring the overall abundance of individuals in addition to metrics of taxonomic, functional, or phylogenetic diversity, thus confirming the importance of population abundance as an essential biodiversity variable.

Biodiversity mitigates trade-offs among species functional traits underpinning multiple ecosystem services

Tidskriftsartikel (refereegranskat)abstract
- Biodiversity loss and its effects on humanity is of major global concern. While a growing body of literature confirms positive relationships between biodiversity and multiple ecological functions, the links between biodiversity, ecological functions and multiple ecosystem services is yet unclear. Studies of biodiversity-functionality relationships are mainly based on computer simulations or controlled field experiments using only few species. Here, we use a trait-based approach to integrate plant functions into an ecosystem service assessment to address impacts of restoration on species-rich grasslands over time. We found trade-offs among functions and services when analysing contributions from individual species. At the community level, these trade-offs disappeared for almost all services with time since restoration as an effect of increased species diversity and more evenly distributed species. Restoration to enhance biodiversity also in species-rich communities is therefore essential to secure higher functional redundancy towards disturbances and sustainable provision of multiple ecosystem services over time.

- Financial advisers recommend a diverse portfolio to respond to market fluctuations across sectors. Similarly, nature has evolved a diverse portfolio of species to maintain ecosystem function amid environmental fluctuations. In urban planning, public health, transport and communications, food production, and other domains, however, this feature often seems ignored. As we enter an era of unprecedented turbulence at the planetary level, we argue that ample responses to this new reality — that is, response diversity — can no longer be taken for granted and must be actively designed and managed. We describe here what response diversity is, how it is expressed and how it can be enhanced and lost.

- Despite the growing knowledge that food system solutions should account for interactions and drivers across scales, broader societal debate on how to solve food system challenges is often focused on two dichotomous perspectives and associated solutions: either more localized food systems or greater global coordination of food systems. The debate has found problematic expressions in contemporary challenges, prompting us to revisit the role that resilience thinking can play when faced with complex crises that increase uncertainty. Here we identify four ‘aching points’ facing food systems that are central points of tension in the local–global debate. We apply the seven principles of resilience to these aching points to reframe the solution space to one that embeds resilience into food systems’ management and governance at all scales, supporting transformative change towards sustainable food systems.
