Living within planetary limits requires attention to justice as biophysical boundaries are not inherently just. Through collaboration between natural and social scientists, the Earth Commission defines and operationalizes Earth system justice to ensure that boundaries reduce harm, increase well-being, and reflect substantive and procedural justice.

Living within planetary limits requires attention to justice as biophysical boundaries are not inherently just. Through collaboration between natural and social scientists, the Earth Commission defines and operationalizes Earth system justice to ensure that boundaries reduce harm, increase well-being, and reflect substantive and procedural justice. Such stringent boundaries may also affect ‘just access’ to food, water, energy and infrastructure. We show how boundaries may need to be adjusted to reduce harm and increase access, and challenge inequality to ensure a safe and just future for people, other species and the planet. Earth system justice may enable living justly within boundaries. Show less

Sustainability-focused research networks and communities of practice have emerged as a key response and strategy to build capacity and knowledge to support transformation towards more sustainable, just and equitable futures. This paper synthesises insights from the development of a community of practice on social-ecological systems (SES) research in southern Africa over the past decade, linked to the international Programme on Ecosystem Change and Society (PECS). This community consists of a network of researchers who carry out place-based SES research in the southern African region. They interact through various cross-cutting working groups and also host a variety of public colloquia and student and practitioner training events. Known as the Southern African Program on Ecosystem Change and Society (SAPECS), its core objectives are to: (1) derive new approaches and empirical insights on SES dynamics in the southern African context; (2) have a tangible impact by mainstreaming knowledge into policy and practice; and (3) grow the community of practice engaged in SES research and governance, including researchers, students and practitioners. This paper reflects on experiences in building the SAPECS community, with the aim of supporting the development of similar networks elsewhere in the world, particularly in the Global South.

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.

Over the last 2 decades, it has become increasingly evident that incremental adaptation to global environmental challenges—particularly climate change—no longer suffices. To make matters worse, systemic problems such as social inequity and unsustainable use of resources prove to be persistent. These challenges call for, such is the rationale, significant and radical systemic changes that challenge incumbent structures. Remarkably, scholarship on sustainability transformations has only engaged with the role of power dynamics and shifts in a limited fashion. This paper responds to a need for methods that support the creation of imaginative transformation pathways while attending to the roles that power shifts play in transformations. To do this, we extended the “Seeds of Good Anthropocenes” approach, incorporating questions derived from scholarship on power into the methodology. Our ‘Disruptive Seeds’ approach focuses on niche practices that actively challenge unsustainable incumbent actors and institutions. We tested this novel approach in a series of participatory pilot workshops. Generally, the approach shows great potential as it facilitates explicit discussion about the way power shifts may unfold in transformations. It is a strong example of the value of mixing disciplinary perspectives to create new forms of scenario thinking—following the call for more integrated work on anticipatory governance that combines futures thinking with social and political science research into governance and power. Specifically, the questions about power shifts in transformations used in this paper to adapt the Seeds approach can also be used to adapt other future methods that similarly lack a focus on power shifts—for instance, explorative scenarios, classic back-casting approaches, and simulation gaming.

The Programme on Ecosystem Change and Society (PECS) was established in 2011, and is now one of the major international social-ecological systems (SES) research networks. During this time, SES research has undergone a phase of rapid growth and has grown into an influential branch of sustainability science. In this Perspective, we argue that SES research has also deepened over the past decade, and helped to shed light on key dimensions of SES dynamics (e.g. system feedbacks, aspects of system design, goals and paradigms) that can lead to tangible action for solving the major sustainability challenges of our time. We suggest four ways in which the growth of place-based SES research, fostered by networks such as PECS, has contributed to these developments, namely by: 1) shedding light on transformational change, 2) revealing the social dynamics shaping SES, 3) bringing together diverse types of knowledge, and 4) encouraging reflexive researchers.

The Sustainable Development Goals aim to improve access to resources and services, reduce environmental degradation, eradicate poverty and reduce inequality. However, the magnitude of the environmental burden that would arise from meeting the needs of the poorest is under debate—especially when compared to much larger burdens from the rich. We show that the ‘Great Acceleration’ of human impacts was characterized by a ‘Great Inequality’ in using and damaging the environment. We then operationalize ‘just access’ to minimum energy, water, food and infrastructure. We show that achieving just access in 2018, with existing inequalities, technologies and behaviours, would have produced 2–26% additional impacts on the Earth’s natural systems of climate, water, land and nutrients—thus further crossing planetary boundaries. These hypothetical impacts, caused by about a third of humanity, equalled those caused by the wealthiest 1–4%. Technological and behavioural changes thus far, while important, did not deliver just access within a stable Earth system. Achieving these goals therefore calls for a radical redistribution of resources. Show less

Conservation approaches to social-ecological systems have largely been informed by a framing of preserving nature for its instrumental societal benefits, often ignoring the complex relationship of humans and nature and how climate change might impact these. The Nature Futures Framework (NFF) was developed by the Task Force on scenarios and models of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services as a heuristic approach that appreciates the diverse positive values of nature and its contribution to people. In this overview, we convene a group of experts to discuss the NFF as a tool to inform management in social-ecological systems facing climate change. We focus on three illustrative case studies from the global south across a range of climate change impacts at different ecological levels. We find that the NFF can facilitate the identification of trade-offs between alternative climate adaptation pathways based on different perspectives on the values of nature they emphasize. However, we also identify challenges in adopting the NFF, including how outputs can be translated into modeling frameworks. We conclude that using the NFF to unpack diverse management options under climate change is useful, but that there are still gaps where more work needs to be done to make it fully operational. A key conclusion is that a range of multiple perspectives of people’s values on nature could result in adaptive decision-making and policy that is resilient in responding to climate change impacts in social-ecological systems.

Global biodiversity and ecosystem service models typically operate independently. Ecosystem service projections may therefore be overly optimistic because they do not always account for the role of biodiversity in maintaining ecological functions. We review models used in recent global model intercomparison projects and develop a novel model integration framework to more fully account for the role of biodiversity in ecosystem function, a key gap for linking biodiversity changes to ecosystem services. We propose two integration pathways. The first uses empirical data on biodiversity–ecosystem function relationships to bridge biodiversity and ecosystem function models and could currently be implemented globally for systems and taxa with sufficient data. We also propose a trait-based approach involving greater incorporation of biodiversity into ecosystem function models. Pursuing both approaches will provide greater insight into biodiversity and ecosystem services projections. Integrating biodiversity, ecosystem function, and ecosystem service modeling will enhance policy development to meet global sustainability goals. Show less

Food insecurity and diet-related diseases do not only have detrimental effects to human health, but are also underpinned by food systems that are environmentally unsustainable and culturally disconnected.

Food insecurity and diet-related diseases do not only have detrimental effects to human health, but are also underpinned by food systems that are environmentally unsustainable and culturally disconnected. These challenges in accessing a diverse diet often persist despite biocultural richness. For example, South Africa is globally recognised for its rich biodiversity, an ecologically unrivalled coastline, and a rich body of traditional knowledge amongst wild-food users. In this paper, we explore the potential that coastal wild foods as neglected and underutilised species (NUS) can play in local food systems in South Africa’s Western Cape Province. Following a previously established transformation lab (T-Lab) method, here we report the observations and outcomes emerging from a two-day workshop held in May 2019 with a group of 40 actors involved in the local food system in diverse ways. Farmers, small-scale fishers, indigenous knowledge holders, representatives from non-profit organisations, chefs, bartenders, academics, activists, conservationists, and government officials were brought together with the aim of strengthening an emerging coalition of coastal wild food actors. Findings highlighted the existence of a fledgling economy for coastal wild foods, driven by high-end chefs. The T-Lab was essentially a tool of knowledge co-production around food system transformation and helped to surface deeply embedded issues on land, race, history, and culture that warrant engagement if a better food system is to emerge. In a country that is drought prone and vulnerable to climate change, a more resilient and sustainable food system is a necessity. But defining alternative governance systems to shift towards a healthier, more sustainable, and more equitable food system will require concerted effort across all stakeholders. Show less

Social-ecological systems (SES) research has emerged as an important area of sustainability science, informing and supporting pressing issues of transformation towards more sustainable, just and equitable futures. To date, much SES research has been done in or from the Global North, where the challenges and contexts for supporting sustainability transformations are substantially different from the Global South. This paper synthesises emerging insights on SES dynamics that can inform actions and advance research to support sustainability transformations specifically in the southern African context. The paper draws on work linked to members of the Southern African Program on Ecosystem Change and Society (SAPECS), a leading SES research network in the region, synthesizing key insights with respect to the five core themes of SAPECS: (i) transdisciplinary and engaged research, (ii) ecosystem services and human well-being, (iii) governance institutions and management practices, (iv) spatial relationships and cross-scale connections, and (v) regime shifts, traps and transformations. For each theme, we focus on insights that are particularly novel, interesting or important in the southern African context, and reflect on key research gaps and emerging frontiers for SES research in the region going forward. Such place-based insights are important for understanding the variation in SES dynamics around the world, and are crucial for informing a context-sensitive global agenda to foster sustainability transformations at local to global scales.

An erosion of indigenous and traditional foods in the Global South has dramatically changed the global food system in the last 50 years. Reinvigorating these crops and the agro-biodiversity that they represent could provide benefits for healthier and more sustainable food systems. In South Africa, it has been proposed that studying indigenous plants more extensively and focussing on innovation to include them as mainstream foods on people's plates could improve food and nutrition security. With this background, this paper aims to contribute to addressing this challenge by researching sorghum (Sorghum bicolor) to identify the opportunities for innovating around sorghum as a healthy food and resilient crop. The paper traces sorghum through various encounters across the South African food system. The results point at clear areas where policy interventions could bolster the sorghum value chain. These include zero-rating VAT on sorghum products, investing more extensively in research and marketing across diverse stakeholders, raising awareness about the health benefits of sorghum and using public procurement as a way of instigating a market for novel sorghum products. The outcomes of a successful sorghum innovation programme could improve smallholder farmers' livelihoods, make a healthy food more accessible to South Africans and develop a local market for innovative products that utilize a crop that is resilient to projected climatic changes.

Achieving global sustainability goals requires most people and societies to fundamentally revisit their relationship with nature. New approaches are called for to guide change processes towards sustainable futures that embrace the plurality of people’s desired relationships with nature. This paper presents a novel approach to exploring desirable futures for nature and people that was developed through an application in Nationaal Park Hollandse Duinen in the Netherlands. This new national park is developed bottom-up by a diverse group of actors reshaping their interactions with each other and with nature. Our approach, co-designed with key stakeholders of the national park, engages with a new pluralistic framework for human-nature relationships presented by the IPBES task force on scenarios and models to catalyze the development of nature-centered scenarios. We integrated this Nature Futures Framework with the Three Horizons Framework in a participatory workshop process designed to bring people’s diverse relationships with nature to the fore, and jointly envision desirable futures and the pathways to get there. We present a methodology to analyze and compare the visions and assess their potential contribution to the SDGs. We summarize the results of the application in Nationaal Park Hollandse Duinen and reflect on lessons learned. The approach successfully engaged participants in joint exploration of desirable futures for the national park based on their plural perspectives on human-nature relationships. We see much potential for its applications to support change processes in various social-ecological contexts toward more sustainable futures for nature and people. Show less

Models help decision-makers anticipate the consequences of policies for ecosystems and people; for instance, improving our ability to represent interactions between human activities and ecological systems is essential to identify pathways to meet the 2030 Sustainable Development Goals. However, use of modeling outputs in decision-making remains uncommon. We share insights from a multidisciplinary National Socio-Environmental Synthesis Center working group on technical, communication, and process-related factors that facilitate or hamper uptake of model results. We emphasize that it is not simply technical model improvements, but active and iterative stakeholder involvement that can lead to more impactful outcomes. In particular, trust- and relationship-building with decision-makers are key for knowledge-based decision making. In this respect, nurturing knowledge exchange on the interpersonal (e.g., through participatory processes) and institutional level (e.g., through science-policy interfaces across scales) represents a promising approach. To this end, we offer a generalized approach for linking modeling and decision-making. Show less

International experience reveals that food policy development often occurs in silos and offers few tangible mechanisms to address the interlinked, systemic issues underpinning food and nutrition insecurity. This paper investigated what South African government policies cover in terms of different aspects of the food system, who is responsible for them, and how coordinated they are. Policy objectives were categorized into seven policy domains relevant to food systems: agriculture, environment, social protection, health, land, education, economic development, and rural development. Of the ninety-one policies reviewed from 1947–2017, six were identified as being "overarching" with goals across all the domains. About half of the policies focused on agriculture and the environment, reflecting an emphasis on agricultural production. Policies were formulated and implemented in silos. As a result, learning from implementation, and adjusting to improve impact has been limited. Particularly important is that coordination during implementation, across these complex domains, has been partial. In order to achieve its stated food and nutrition outcomes, including Sustainable Development Goal (SDG) 2, South Africa needs to translate its policies into tangible, practical plans and processes guided by effective coordination and alignment. Key recommendations are practically to align policies to a higher-level "food goal", establish better coordination mechanisms, consolidate an effective monitoring and evaluation approach to address data gaps and encourage learning for adaptive implementation. Actively engaging the existing commitments to the SDGs would draw stated international commitments together to meet the constitutional commitment to food rights into an overarching food and nutrition security law.

Transitioning towards sustainable diets is imperative to avoid the worst effects of climate change, environmental degradation, and malnutrition. In South Africa, households most vulnerable to food insecurity employ various strategies to access food. These include purchasing hampers; a combination of staple foods sold in bulk at a discounted price, which are cake wheat flour, super maize meal, white sugar, cooking oil, and white parboiled rice. We explore the barriers and opportunities for hampers to advance sustainable diets in the context of Cape Town. Our findings show hampers contain energy-dense, nutrient-poor foods. Furthermore, we find that brand loyalty plays an important role in households’ purchase of hampers. We conclude there is potential to leverage hampers to become a sustainable strategy through which people can access healthier food by working with retailers to offer nutritious and sustainably produced alternatives. Such change would require challenging retailers’ and consumers’ understanding of what ‘necessities’ are. Show less

As human activity threatens to make the planet unsafe for humanity and other life forms, scholars are identifying planetary targets set at a safe distance from biophysical thresholds beyond which critical Earth systems may collapse. Yet despite the profound implications that both meeting and transgressing such targets may have for human wellbeing, including the potential for negative trade-offs, there is limited social science analysis that systematically considers the justice dimensions of such targets. Here we assess a range of views on planetary justice and present three arguments associated with why social scientists should engage with the scholarship on safe targets. We argue that complementing safe targets with just targets offers a fruitful approach for considering synergies and trade-offs between environmental and social aspirations and can inform inclusive deliberation on these important issues.

This paper follows sorghum, an indigenous, but currently underutilized, grain in South Africa, through six encounters to discover its potential to transform the country’s food system. By listening to stories from diverse perspectives, it shows that the re-inclusion of sorghum could not only diversify diets, but could also move toward breaking colonial stereotypes of what constitutes aspirational food. It employs a Follow the Thing method to unpack the multiple identities of sorghum and the role it could play in galvanizing a healthier, more diverse food system. By opening up to a radical following method that does not constrain the researcher, the underlying stories associated with sorghum are highlighted, which coincides with a shift in perception of the multiple potentialities that the crop embodies. The research highlights that a strong cultural link to sorghum remains in South Africa and that if innovation could be broadly interpreted, this might invigorate a richer engagement with sorghum, not just as a commodity, but as a culturally significant food.

Future scenarios and pathways of potential development trajectories are powerful tools to assist with decision-making to address many sustainability challenges. Such scenarios play a major role in global environmental assessments (GEAs). Currently, however, scenarios in GEAs are mostly developed at the global level by experts and researchers, and locally imagined, bottom-up scenarios do not play a role in such assessments. In this paper, we argue that addressing future sustainability challenges for achieving more equitable development in GEAs requires a more explicit role for bottom-up inspired futures. To this end, this paper employs an innovative global assessment framework for exploring alternative futures that are grounded in local realities and existing practical actions, and that can be appropriately scaled to the required decision-making level. This framework was applied in the context of the UN’s Global Environment Outlook 6, a major example of a GEA. We developed novel methods for synthesizing insights from a wide range of local practices and perspectives into global futures. We collected information from crowdsourcing platforms, outcomes of participatory workshops in different regions of the world, and an assessment of reported regional outlooks. We analysed these according to a framework also used by an integrated assessment model in the same GEA. We conclude that bottom-up approaches to identify and assess transformative solutions that envision future pathways towards greater sustainability significantly strengthen current GEA scenario-development approaches. They provide decision makers with required actionable information based on tangible synergistic solutions that have been tested on the ground. This work has revealed that there are significant opportunities for the integration of bottom-up knowledge and insights into GEAs, to make such assessments more salient and valuable to decision makers.

Facilitated dialogues often draw on action research to enable deeper learning while also providing opportunity for action research to interrogate dialogue-into-action (Chapter 15). They also often make use of visioning or imagining the future to liberate participants to transcend the constraints of the present and so explore potential pathways to a better outcome. There is a strong link to the discussions on futures analysis in Chapter 10 and scenario development in Chapter 11.

Global Environmental Assessments (GEAs) are in a unique position to influence environmental decision-making in the context of sustainability challenges. To do this effectively, however, new methods are needed to respond to the needs of decision-makers for a more integrated, contextualized and goal-seeking evaluation of different policies, geared for action from global to local. While scenarios are an important tool for GEAs to link short-term decisions and medium and long-term consequences, these current information needs cannot be met only through deductive approaches focused on the global level. In this paper, we argue that a more diverse set of futures tools operating at multiple scales are needed to improve GEA scenario development and analysis to meet the information needs of policymakers and other stakeholders better. Based on the literature, we highlight four challenges that GEAs need to be able to address in order to contribute to global environmental decision-making about the future: 1. anticipate unpredictable future conditions; 2. be relevant at multiple scales, 3. include diverse actors, perspectives and contexts; and 4. leverage the imagination to inspire action. We present a toolbox of future-oriented approaches and methods that can be used to effectively address the four challenges currently faced by GEAs. Show less

Throughout the world, biodiversity and nature's contributions to people are under threat, with clear changes evident. Biodiversity and ecosystem services have particular value in Africa– yet they are negatively impacted by a range of drivers, including land use and climate change. In this communication, we show evidence of changing biodiversity and ecosystem services in Africa, as well as the current most significant drivers of change. We then consider five plausible futures for the African continent, each underlain by differing assumptions. In three out of the five futures under consideration, negative impacts on biodiversity and ecosystem services are likely to persist. Those two plausible futures prioritizing environment and sustainability, however, are shown as the most likely paths to achieving long term development objectives without compromising the continent's biodiversity and ecosystem services. Such a finding shows clearly that achievement of such objectives cannot be separated from full recognition of the value of such services. Show less

It proposes that narratives from non-Western cultures offer more nuanced and diverse approaches to decision-making under conditions of uncertainty than the archetypical scenarios depicted in current models. This chapter uses science fiction from sub-Saharan Africa as a source for more experiential decision-making that emphasizes a decolonial agenda, which could shape and change the way we use quantitative modelling to consider future trajectories for the planet in the age of the Anthropocene.

Decades of research and policy interventions on biodiversity have insufficiently addressed the dual issues of biodiversity degradation and social justice. New approaches are therefore needed. We devised a research and action agenda that calls for a collective task of revisiting biodiversity toward the goal of sustaining diverse and just futures for life on Earth. Revisiting biodiversity involves critically reflecting on past and present research, policy, and practice concerning biodiversity to inspire creative thinking about the future. The agenda was developed through a 2-year dialogue process that involved close to 300 experts from diverse disciplines and locations. Recognizing knowledge, action, and ethics as inseparable, we synthesized a set of principles that help navigate the task of revisiting biodiversity. The agenda articulates 4 thematic areas for future research. First, researchers need to revisit biodiversity narratives by challenging conceptualizations that exclude diversity and entrench the separation of humans, cultures, economies, and societies from nature. Second, researchers should focus on the relationships between the Anthropocene, biodiversity, and culture by considering humanity and biodiversity as tied together in specific contexts. Third, researchers should focus on nature and economies by better accounting for the interacting structures of economic and financial systems as core drivers of biodiversity loss. Finally, researchers should enable transformative biodiversity research and action by reconfiguring relationships between human and nonhuman communities in and through science, policy, and practice. Revisiting biodiversity necessitates a renewed focus on dialogue among biodiversity communities and beyond that critically reflects on the past to channel research and action toward fostering just and diverse futures for human and nonhuman life on Earth.

The conventional dominant global agri-food system is a main driver in the Anthropocene: food production entails profound global environmental changes from greenhouse gas emissions to biodiversity loss, and shifting diets further impact planetary and human health. Innovative approaches are needed to shift towards more sustainable, equitable and healthy agri-food systems. Building on the increasing recognition of the relevance of traditional agroecological knowledge (TAeK) in sustainable food systems, this paper aims to describe innovative agri-food initiatives and explore how the use and valorization of TAeK may transform conventional agri-food systems. It employs a case-study approach in Spain, where we conducted semi-structured interviews with 12 representatives of alternative agri-food initiatives. We found that, to promote sustainable agri-food systems, TAeK has to span from farm-to-fork. Innovative agroecological practices and knowledge help to safeguard biocultural diversity, while gastronomic knowledge among consumers on how to process and prepare local varieties and species is crucial for the implementation of shorter value chains. We discuss how TAeK enhances the success of conventional systems of innovation, challenging dominant epistemological frameworks. By scaling deep (changing values), scaling out (dissemination, reproduction) and scaling up (changing institutions), the agri-food initiatives may act on leverage points to enable broader transformation of the Spanish agri-food system.

Business as usual or transformative change? While the global agro-industrial food system is credited with increasing food production, availability and accessibility, it is also credited with giving birth to ‘new’ challenges such as malnutrition, biodiversity loss, and environmental degradation. We reviewed the potential of underutilized indigenous and traditional crops to bring about a transformative change to South Africa’s food system. South Africa has a dichotomous food system, characterized by a distinct, dominant agro-industrial, and, alternative, informal food system. This dichotomous food system has inadvertently undermined the development of smallholder producers. While the dominant agro-industrial food system has led to improvements in food supply, it has also resulted in significant trade-offs with agro-biodiversity, dietary diversity, environmental sustainability, and socio-economic stability, especially amongst the rural poor. This challenges South Africa’s ability to deliver on sustainable and healthy food systems under environmental change. The review proposes a transdisciplinary approach to mainstreaming underutilized indigenous and traditional crops into the food system, which offers real opportunities for developing a sustainable and healthy food system, while, at the same time, achieving societal goals such as employment creation, wellbeing, and environmental sustainability. This process can be initiated by researchers translating existing evidence for informing policy-makers. Similarly, policy-makers need to acknowledge the divergence in the existing policies, and bring about policy convergence in pursuit of a food system which includes smallholder famers, and where underutilized indigenous and traditional crops are mainstreamed into the South African food system Show less

Transformations toward sustainability have recently gained traction, triggered in part by a growing recognition of the dramatic socio-cultural, political, economic, and technological changes required to move societies toward more desirable futures in the Anthropocene. However, there is a dearth of literature that emphasizes the crucial aspects of sustainability transformations in the diverse contexts of the Global South. Contributors to this Special Feature aim to address this gap by weaving together a series of case studies that together form an important navigational tool on the “how to” as well as the “what” and the “where to” of sustainability transformations across diverse challenges, sectors, and geographies. They propose the term “transformative space” as a “safe-enough” collaborative process whereby actors invested in sustainability transformations can experiment with new mental models, ideas, and practices that can help shift social-ecological systems onto more desirable pathways. The authors also highlight the challenges posed to researchers as they become “transformative space-makers,” navigating the power dynamics inherent in these processes. Because researchers and practitioners alike are challenged to provide answers to complex and often ambiguous or incomplete questions around sustainability, the ideas, reflections and learning gathered in this Special Feature provide some guidance on new ways of engaging with the world.

Since 2002, a range of South African policies have attempted to address the disproportionate burden of food and nutrition insecurity on the population. Yet malnutrition among the poor has worsened. This study reviewed policies to examine their implications for food security and the treatment of malnutrition. Policies enacted between 2002 and 2017 were retrieved from government departments and the data were thematically analysed. A preliminary analysis shows that policy has aided production through input provision and capacity building. Taxation, school nutrition programmes and social grants are some of the food access initiatives, whilst micronutrient supplementation, breastfeeding campaigns and food fortification are policies specifically focused on nutrition. However, despite these interventions, food insecurity has remained due to gaps in and contradictions among policies and the lack of coordination in policy development and implementation, especially across sectors. To improve food and nutrition security, government must better engage with ideas about how to address food and nutrition security systemically, and develop the appropriate coordination mechanisms for a more holistic approach to this challenge.

The unique challenges posed by the Anthropocene require creative ways of engaging with the future and bringing about transformative change. Envisioning positive futures is a first step in creating a shared understanding and commitment that enables radical transformations toward sustainability in a world defined by complexity, diversity, and uncertainty. However, to create a transformative space in which truly unknowable futures can be explored, new experimental approaches are needed that go beyond merely extrapolating from the present into archetypal scenarios of the future. Here, we present a process of creative visioning where participatory methods and tools from the field of futures studies were combined in a novel way to create and facilitate a transformative space, with the aim of generating positive narrative visions for southern Africa. We convened a diverse group of participants in a workshop designed to develop radically different scenarios of good Anthropocenes, based on existing “seeds” of the future in the present. These seeds are innovative initiatives, practices, and ideas that are present in the world today, but are not currently widespread or dominant. As a result of a carefully facilitated process , creative immersion, and grappling with deeply held assumptions, four radical visions for southern Africa were produced. Although these futures are highly innovative and exploratory, they still link back to current real-world initiatives and contexts. The key learning that arose from this experience was the importance of the imagination for transformative thinking, the need to capitalize on diversity to push boundaries, and finally, the importance of creating a space that enables participants to engage with emotions, beliefs, and complexity. This method of engagement with the future has the potential to create transformative spaces that inspire and empower people to act toward positive Anthropocene visions despite the complexity of sustainability.

Wide agreement exists that the “Anthropocene” demands new forms of engagement and responses to achieve sustainability, but different fields suggest quite different approaches. In this communication, we set out four perspectives that we argue have fundamentally different framings of the “problem” of the Anthropocene, and consequently point to very different responses to achieving sustainability. These four fields include: the eco-modernist perspective, the planetary stewardship paradigm, the pathways to sustainability approach, and the critical post-humanist paradigm. We suggest that a deeper underlying framing which can help integrate aspects of these four perspectives is an understanding of the “Anthropocene as responsibility”. We argue that from this perspective it becomes possible to engage with an ethics of responsibility that comes with being human and acting on the planet, in the face of an uncertain and unknowable future.

Repeated food crises have resulted in increased recognition of the boundary-spanning nature of governing food systems and in consequent calls for more holistic food governance. An increasing number of governments have followed up on this recognition by initiating or discussing the development of better integrated food policy. However, in spite of the emergence of integrated food policy as a policy paradigm worth pursuing, considerable challenges remain regarding its concrete realization. Drawing upon recent insights from the public policy literature, this policy letter sets out five particularly demanding areas of concern: (i) constructing a resonating policy frame, (ii) formulating policy goals, (iii) involving relevant sectors and levels, (iv) the question of what constitutes optimal policy integration, and (v) designing a consistent mix of policy instruments. Formulating answers to these challenges will enable policymakers and stakeholders to envision the next steps in concretizing integrated food policy. Show less

Much of African agriculture’s vulnerability to climate change lies in the fact that its agricultural systems remain largely rain-fed and underdeveloped, as the majority of Africa’s farmers are small-scale farmers with few financial resources, limited access to infrastructure, and disparate access to information. At the same time, as these systems are highly reliant on their environment, and farmers are dependent on farming for their livelihoods, their diversity, context specificity, and the existence of generations of traditional knowledge offer elements of resilience in the face of climate change. Climate change will impact farmers and their agricultural systems in different ways, and adapting to these impacts will need to be context-specific. Current adaptation efforts on the continent are increasing across the continent, but it is expected that in the long term these will be insufficient in enabling communities to cope with the changes due to longer-term climate change. African famers are increasingly adopting a variety of conservation and agroecological practices such as agroforestry, contouring, terracing, mulching, and no-till. These practices have the twin benefits of lowering carbon emissions while adapting to climate change as well as broadening the sources of livelihoods for poor farmers, but there are constraints to their widespread adoption. These challenges vary from insecure land tenure to difficulties with knowledge-sharing. While African agriculture faces exposure to climate change as well as broader socioeconomic and political challenges, many of its diverse agricultural systems remain resilient. As the continent with the highest population growth rate, rapid urbanization trends, and rising GDP in many countries, Africa’s agricultural systems will need to become adaptive to more than just climate change as the uncertainties of the 21st century unfold.

The scale, rate, and intensity of humans’ environmental impact has engendered broad discussion about how to find plausible pathways of development that hold the most promise for fostering a better future in the Anthropocene. However, the dominance of dystopian visions of irreversible environmental degradation and societal collapse, along with overly optimistic utopias and business-as-usual scenarios that lack insight and innovation, frustrate progress. Here, we present a novel approach to thinking about the future that builds on experiences drawn from a diversity of practices, worldviews, values, and regions that could accelerate the adoption of pathways to transformative change (change that goes beyond incremental improvements). Using an analysis of 100 initiatives, or “seeds of a good Anthropocene”, we find that emphasizing hopeful elements of existing practice offers the opportunity to: (1) understand the values and features that constitute a good Anthropocene, (2) determine the processes that lead to the emergence and growth of initiatives that fundamentally change human–environmental relationships, and (3) generate creative, bottom-up scenarios that feature well-articulated pathways toward a more positive future.

There is overwhelming evidence that the national food system in South Africa is in crisis, without any clear or shared understanding of a pathway toward a more sustainable configuration. Indeed, given several powerful trends that seem set to continue, there is a high level of urgency required for change: alternative pathways are required more than ever. In this chapter, we outline some key interventions that are being made across the food system in an attempt to shift the system onto a more desirable pathway. Although in no way a comprehensive analysis of all the positive inroads being made to shift the food system, there are some key crosscutting recommendations that emerge from this synopsis that can help to reconfigure a new food system with new direction and impetus. New ideas, relationships, and commitment to change must be facilitated by strengthening the grassroots initiatives held by civil society, but also by forging new relationships that transcend partisan biases within sectors. Platforms and networks for information sharing are important, as these will enable the identification of new trends and relevant innovations and allow adaption of new ideas for the South African context. Finally, there is a critical need to support youth-led initiatives through skills development and financial investment. No silver bullet that will shift South Africa's food system onto a more sustainable and equitable trajectory. The challenge requires innovative responses and solutions that fundamentally reconsider the system as a whole and move away from fragmented, piecemeal, and difficult to scale initiatives. Show less

The need for developing socially just living conditions for the world’s growing population whilst keeping human societies within a ‘safe operating space’ has become a modern imperative. This requires transformative changes in the dominant social norms, behaviours, governance and management regimes that guide human responses in areas such as urban ecology, public health, resource security (e.g., food, water, energy access), economic development and biodiversity conservation. However, such systemic transformations necessitate experimentation in public arenas of exchange and a deepening of processes that can widen multi-stakeholder learning. We argue that there is an emergent potential in bridging the sustainability transitions and resilience approaches to create new scientific capacity that can support large-scale social-ecological transformations (SETs) to sustainability globally, not just in the West. In this article, we elucidate a set of guiding principles for the design of a ‘safe space’ to encourage stronger interactions between these research areas and others that are relevant to the challenges faced. We envisage new opportunities for transdisciplinary collaboration that will develop an adaptive and evolving community of practice. In particular, we emphasise the great opportunity for engaging with the role of emerging economies in facilitating safe space experimentation. Show less

The vitally important provision of food through the food system is not a simple linear process,
but a contested outcome of a complex system. This systematic literature review was
undertaken to better understand the inherent complexity of this system and inform a long-‐
term scenario-‐planning process aimed at ensuring a food secure future in South Africa. The
past 40 years have seen an emphasis on the notion of 'food security'.

A decline in subsistence agriculture across sub-Saharan Africa has meant an increased role for the private sector in food security strategies, but this role remains a relatively blind spot in food policy. We address this gap by analyzing retailers and consumers in a rural region of South Africa. Our results show that purchasing food is an important food security strategy for the rural poor, but is constrained by a lack of access to income. Furthermore, a reliance on specific non-perishable foodstuffs impacts the micronutrients that the poorest can access if they are unable to grow their own fresh produce. Adaptive food policy thus requires a holistic appreciation of the food system - emphasizing production as well as building livelihoods outside of agriculture. Show less

This report outlines the key themes that emerged at a one-day inter-disciplinary workshop held at the Harvard Kennedy School of Government on Saturday, May 18, 2013, which focused on the question:

What role can the data generated through Information and Communications Technology (ICT) play in aiding decision-making to meet current and future food, energy and water (FEW) needs in the wake of climate change?

The goal of this workshop was to help define an inter-disciplinary, scholarly research agenda to help address this critical question. Its scope was purposefully broad and reflected an attempt to bridge divides across academic disciplines and to foster conversation between technologists, policymakers and academics. The workshop was focused on exploring the current and potential uses of Information and Communication Technologies (ICTs) in the food, energy and water (FEW) sectors and also drawing lessons from the use of ICT in the broader field of development. However, it emerged that the use of ICT for development (“ICTD”) was still evolving and that many of the challenges to the effective deployment of ICT for FEW had parallels in other sectors.

Participants shared experiences from a wide range of development sectors.
Five key areas emerged from the workshop:
the role ICT can play in linking global governance with local knowledge and preferences,
the ethical dilemmas that have arisen in the ICTD context,
how ICTD can inform policy-making across different scales, and
the importance of context in employing ICT tools.

Overall the workshop was judged a great success by all and we hope that it has established fertile ground for future trans-disciplinary research to be conducted in this important space. Show less

Meeting the demand for food, energy, and water as world population increases is a major goal for the food systems of the future. These future challenges, which are complex, multiscalar, and cross-sectoral in nature, require a food systems approach that recognizes the socio-ecological and socio-technical dimensions of food (Ericksen, 2008; Ingram, 2011;Rivera-Ferre, 2012). The United Nations’ Future Earth Program aims to provide a new platform for consolidating the knowledge required for societies to transition to global sustainability (Future Earth Transition Team, 2012). In this paper, we explore how Future Earth could become a vehicle for inspiring the production of new research ideas and collaborations for sustainably transforming the future food system. We do this on the basis of a synthesis of views from 28 young (below 40 years old) food system scientists, representing five continents. Their expertise comes from disciplines including food engineering, agronomy, ecology, geography, psychology, public health, food politics, nutritional science, political science, sociology and sustainability science. This paper begins with an outline of the institutional framework of Future Earth and how it might support innovative transdisciplinary research on food systems, and the position of young scientists within this framework. Secondly, we outline the key insights expressed by the young scientists during the Food Futures Conference in Villa Vigoni, Italy, in April 2013, including the core research questions raised during the meeting as well as some of the challenges involved in realizing their research ambitions within their professional spheres.

1. The extent to which vertebrate carnivores shift facultatively between predation and scavenging has recently been emphasized. Potentially, all carnivores have to do is wait until animals succumb to the debilitating effects of advancing age. However, this may be insufficient because of intense competition among other scavengers and decomposers for food. Moreover, the availability of carcasses of animals dying from causes other than predation varies seasonally, so carnivores must be adapted to exploit various sources of food through the seasonal cycle.
2. We explore how mammalian carnivores cope with seasonality in carrion supply and in prey vulnerability to predation.
3. When carrion is scarce, carnivores can (i) take advantage of temporarily vulnerable segments of prey populations, such as newborn young, heavily pregnant females and males distracted or debilitated by reproduction, (ii) switch to carcass remains left by or stolen from other carnivores, or (iii) exploit small animals and non-animal food sources.
4. Relationships between carnivores tending towards predation or scavenging can be both competitive and facilitative. Top carnivores may provide a supply of carcasses throughout the year, which subsidizes scavengers when carrion availability from other sources is low.
5. Megaherbivores, which are not normally regarded as prey but can provide huge carrion subsidies, may strongly influence interspecific interactions between carnivores and the proportion of food flowing towards scavenging relative to predation.
6. Relationships among carnivores based on hunting vs. scavenging strategies are flexible and subject to changes in response to circumstances. Their functional complexity is relevant for assessing the effects of global change on ecosystem function. Show less

The food system is facing unprecedented pressure from environmental change exacerbated by the expansion of agri-food corporations that are consolidating their power in the global food chain. Although Africa missed the Green Revolution and the wave of supermarket expansion that hit the West and then spread to Asia and Latin America, this is unlikely to continue. With a large proportion of sub-Saharan African countries’ GDP still heavily reliant on agriculture, global trends in agri-food business are having an increasing impact on African countries. South Africa, a leader in agribusiness on the continent, has a well-established agri-food sector that is facing increasing pressure from various social and environmental sources. This paper uses interview data with corporate executives from South African food businesses to explore how they are adapting to the dual pressures of environmental change and globalisation. It shows that companies now have to adapt to macro-trends both within and outside the formal food sector and how this in turn has repercussions for building sustainable farming systems—both small and large-scale. It concludes with the recognition that building a sustainable food system is a complex process involving a diversity of actors, however changes are already being seen. Businesses have strategically recognised the need to align the economic bottom line with social and environmental factors, but real sustainability will only happen when all stakeholders are included in food governance.

The food system is now a globalised, interconnected socioecological system and the global South is increasingly being integrated into this new, interconnected, efficiency-driven model.

There are three key outcomes of a wellfunctioning food system: food security, social welfare and environmental welfare (see Figure 1) yet, our current system has so far failed to provide these for the planet’s poor. How, then, will the future food system respond to the challenge of providing food security whilst also adapting to issues of rapid environmental and sustainability issues – most notably climate change? Developing a system of adaptive governance to meet these challenges is clearly an important area for research, but it requires an understanding of the complexity and uncertainty inherent in such measures.
