Resilience is a cross-disciplinary concept that is relevant for understanding the sustainability of the social and environmental conditions in which we live. Most research normatively focuses on building or strengthening resilience, despite growing recognition of the importance of breaking the resilience of, and thus transforming, unsustainable social-ecological systems. Undesirable resilience (cf. lock-ins, social-ecological traps), however, is not only less explored in the academic literature, but its understanding is also more fragmented across different disciplines. This disparity can inhibit collaboration among researchers exploring interdependent challenges in sustainability sciences. In this article, we propose that the term lock-in may contribute to a common understanding of undesirable resilience across scientific fields.

Digitalization coevolves with and fosters three revolutions in urban transport: sharing, electrification and automatization. This dynamic poses severe risks for social and environmental sustainability. Only strong public policies can steer digitalization towards fostering sustainability in urban transport.

Until the past half-century, all agriculture and land management was framed by local institutions strong in social capital. But neoliberal forms of development came to undermine existing structures, thus reducing sustainability and equity. The past 20 years, though, have seen the deliberate establishment of more than 8 million new social groups across the world. This restructuring and growth of rural social capital within specific territories is leading to increased productivity of agricultural and land management systems, with particular benefits for those previously excluded. Further growth would occur with more national and regional policy support.

Under the Paris Agreement, nations have committed to preventing dangerous global warming. Scenarios for achieving net-zero emissions in the second half of this century depend on land (forests and bioenergy) to remove carbon from the atmosphere. Modelled levels of land-based mitigation could reduce the availability of productive agricultural land, and encroach on natural land, with potentially significant social and environmental consequences. However, these issues are poorly recognized in the policy-uptake of modelled outputs. Understanding how science and policy interact to produce expectations about mitigation pathways allows us to consider the trade-offs inherent in relying on land for mitigation.

The sustainability concept seeks to balance how present and future generations of humans meet their needs. But because nature is viewed only as a resource, sustainability fails to recognize that humans and other living beings depend on each other for their well-being. We therefore argue that true sustainability can only be achieved if the interdependent needs of all species of current and future generations are met, and propose calling this ‘multispecies sustainability’. We explore the concept through visualizations and scenarios, then consider how it might be applied through case studies involving bees and healthy green spaces.

Projections of a burgeoning population coupled with global environmental change offer an increasingly dire picture of the state of the world's food security in the not-too-distant future. But how can we transform the current food system to become more sustainable, more equitable and more just? We identify kitchens as sites of transformative innovation in the food system where cooks and chefs can leverage traditional food knowledge about local food species to create delicious and nutritious dishes. Achieving a sustainable food system is a grand challenge, one where cooks in particular are stepping forward as innovators to find solutions.

Technologies and practices to remove carbon from the atmosphere (‘negative emissions technologies’) will be challenging to scale-up. Efforts to incentivize or govern their scale-up globally risk failing if they miss the social challenges. This paper analyzes prospective challenges for negative emissions through examining how decarbonization practices are evolving in one particular landscape: the Imperial Valley in southeast California, a desert landscape engineered for industrial agriculture. Based on semi-structured interviews and site visits, this paper examines how community actors have received, participated in, imagined or contested new energy technologies and climate practices, and draws out takeaways for negative emissions policy.

Despite efforts to address the global forest crisis, deforestation and degradation continue, so we need to urgently revisit possible solutions. A failure to halt the global forest crisis contributes to climate change and biodiversity loss and will continue to result in inequalities in access to, and benefits from, forest resources. In this paper, we unpack a series of powerful myths about forests and their management. By exposing and better understanding these myths and what makes them so persistent, we have the basis to make the social and political changes needed to better manage and protect forests globally.

Most of the water humans consume is for agriculture. Rapidly increasing water demand has led to overexploitation of water resources in many important food-producing regions. In particular, growing groundwater-based irrigation causes potentially damaging depletion. Food systems are increasingly globalized, leading to large export-oriented production. Much research has focused on quantifying the amount of water resources embedded in traded products, but less attention has been given to the role of groundwater use and the related sustainability of agriculture globally. We assess current knowledge of virtual water trade in light of groundwater use and sustainability and highlight remaining challenges in this field.

The climate crisis requires nations to achieve human well-being with low national levels of carbon emissions. Countries vary from one another dramatically in how effectively they convert resources into well-being, and some nations with low levels of emissions have relatively high objective and subjective well-being. We identify urgent research and policy agendas for four groups of countries with either low or high emissions and well-being indicators. Least studied are those with low well-being and high emissions. Understanding social and political barriers to switching from high-carbon to lower-carbon modes of production and consumption, and ways to overcome them, will be fundamental.

We present a view on global marine fisheries that emphasizes mitigating the conflict between sustainability and the scale of industrial exploitation driven by the demand of continuous economic growth. We then summarize the current state of global fisheries. Finally, we advocate strongly for scaling back industrial fisheries, most of which are non-sustainable. This can be achieved through eliminating the harmful, capacity-enhancing subsidies that prop up industrial fisheries to continue operating despite declining fish stocks. Instead, we propose to support well-managed, locally owned and operated small-scale fisheries, which generally contribute more to local employment and food security. We stress that contrary to deep-seated opinion in the fishing industry and among politicians, reducing overfishing by eliminating overcapacity in fishing fleets will actually lead to greater, not reduced catches. This would address part of the increased global seafood demand over the coming decades, which is driven by population and wealth growth. This seems counterintuitive, but is supported by fisheries science, data and experiences. Thankfully, we are beginning to see that some of these changes are being pursued by a growing number of countries and international institutions.

The El Niño event in 2015/2016 was one of the strongest since at least 1950. Through surveys and interviews with key informants, we found businesses in the capital cities of Zambia, Botswana and Kenya experienced major disruption to their activities from El Niño related hydroelectric load shedding, water supply disruption and flooding, respectively. Yet, during the 2015/2016 El Niño, fluctuations in precipitation were not extreme considering the strength of the El Niño event. Results therefore highlight that even fairly moderate precipitation anomalies can contribute to major disruption to economic activity. Addressing the risk of disruption – and supporting the private sector to adapt – is a development priority.

Agriculture provides many benefits to people, such as producing food and creating jobs in rural areas, but it can also have negative impacts on the environment. We analysed existing monitoring indicators for the European Union's Common Agricultural Policy (CAP) to evaluate whether the CAP is effectively achieving multiple social and environmental goals. We found that the current CAP monitoring system is unable to balance many potentially competing goals because its indicators are biased towards a few objectives. We suggest the European Union and its Member States adopt a broader set of indicators covering clear targets when the policy is reformed after 2020.

We argue that the ways in which we as humans derive well-being from nature – for example by harvesting firewood, selling fish or enjoying natural beauty – feed back into how we behave towards the environment. This feedback is mediated by institutions (rules, regulations) and by individual capacities to act. Understanding these relationships can guide better interventions for sustainably improving well-being and alleviating poverty. However, more attention needs to be paid to how experience-related benefits from nature influence attitudes and actions towards the environment, and how these relationships can be reflected in more environmentally sustainable development projects.

Biodiversity footprinting links consumers to the biodiversity pressure their consumption induces, thereby informing choices and enabling participation in remediation measures. In order for countries, cities and households to reduce their impacts it is useful to know more precisely what the various drivers of their footprints are. Here we ask: do urban or rural areas in Europe exert higher biodiversity footprints? And how strongly coupled are income and biodiversity losses? Studying urban versus rural households at the country level in Europe, we found both have generally similar footprints, but that higher income households clearly drive higher footprints.
