The unabated growth of natural resource consumption raises risks that we will outstrip the capacities of ecosystems and governance institutions. At the same time, to achieve important global goals related to poverty alleviation, public health, equity and economic development such as those embodied in the United Nations Sustainable Development Goals (SDGs), we will simultaneously need more resources and better management of natural resources everywhere.
Achieving the UN’s Sustainable Development Goals will require successful efforts to better integrate resource management across local, regional and global scales if greater ecological degradation, erosion of livelihoods and threats to security are to be avoided. Can resource governance be substantially improved across and between multiple types of resources, and become integrated with SDG implementation?
Debates about increasing and interconnected natural resource consumption, waste, and governance are often framed in terms of a “resource nexus.” We define the resource nexus as a set of context-specific critical interlinkages between two or more natural resources used in delivery chains in systems that provide water, energy, food, land, and materials. These dynamic chains involve complex social relations across scales and time, posing significant governance challenges. If “nexus” is to be more than an buzz word, as Nature suggested, approaches invoking the concept must add analytical clarity and apply to governance.
Past resource governance focused mostly on single resource categories such as water or energy in a supply chain running from primary natural resource, through processing and distribution to final consumption and disposal. The nexus concept is a response to this kind of siloed thinking. It emphasizes the importance of examining critical interlinkages across resources.
Our recent article in Nature Sustainability presents a five-node concept of the resource nexus and a set of analytical methods, modelling approaches, and scenarios for assessing system implications and capturing the dynamics for existing interlinkages and for future strategies, as well as building knowledge about these interdependencies. We argue that multi-scale, polycentric resource governance and assessment, in dialogue with various modelling efforts, can inform policy choices in the public, private, and civil society sectors.
A large and growing group of analysts and authors from around the world have been discussing nexus approaches since at least 2011. Our nexus approaches explore interlinkages between five resource sets: water, energy, food, materials, and land. Seeking improved assessment and governance of these links is critical if the SDGs on zero hunger (SDG 2), clean water and sanitation (SDG 6), affordable and clean energy (SDG 7), sustainable cities and communities (SDG 11), responsible consumption and production (SDG 12), climate action (SDG 13), and sustainable use of terrestrial ecosystems (SDG 15) are to be achieved. For example, water resources are centrally important not only for SDG 6 (clean water and sanitation), where it is the explicit subject, but also for SDGs 2 (zero hunger), 7 (affordable and clean energy), 11 (sustainable cities and communities), and 12 (responsible consumption and production).
If water-focused actors, policies, and initiatives seek to achieve SDG 6 without reference to the water-related needs of other SDGs, they may miss opportunities and contradictions. And impediments to SDG achievement would likely to increase. The same holds true for land, food, materials, and energy if you enter inter-resource connections and SDG implementation planning via any one of these resource sets.
Systems thinking is foundational. Researchers and practitioners can start from a broad nexus understanding but may well focus on certain critical interlinkages. Assessment tools such as lifecycle analysis, value chain management, and scenario development and modelling approaches are available to reduce waste and increase efficiencies—sometimes through recapture and reuse—and establish critical resource thresholds to signal major risks of exceeding the capacities of ecosystems and governance institutions at various scales or within sectors. Such tools can potentially link various governance efforts to reduce the ecological and humanitarian costs of mining or agriculture, and simultaneously improve supply chain management and SDG implementation.
Integrated approaches could be better applied to address multiple targets and achieve greater sustainability across public and private sectors and at various levels of scale. And, in the process, such approaches could improve the decidedly uneven and incomplete resource-related monitoring, data gathering and analysis that currently exists across scales.
Modelling and scenario techniques are particularly good for exploring potential future implications for current choices and practices; and helping to identify and visualize demand, supply, and other governance challenges. The five-node nexus can be adapted to specific contexts and should help to focus on the most relevant resource interlinkages across layers. It can also help us further explore interlinkages with biosphere integrity and circular economy, which involves a vision of sustainable resource use that moves beyond the current take-make-dispose extractive industrial model and takes waste out of the equation.
In short, each SDG cannot be achieved in isolation and all SDGs have explicit or implicit resource-related demands and implications. In a world of scarce resources of all kinds—including time—we must prioritize assessment, planning, and governance initiatives that simultaneously maximize and integrate much more sustainable resource management and SDG implementation.

This interview with adelphi’s Daria Ivleva sheds light on China’s Belt and Road Initiative (BRI), and its implications for EU-China relations and global climate action, with a focus on the BRI’s investments in Kazakhstan.
In his address on this year’s World Cities Day, UN-Secretary General António Guterres recognised that “cities have borne the brunt of the pandemic” and called upon governments to “prepare cities for future disease outbreaks”. Authorities cannot waste this opportunity to build back better by simultaneously addressing the increasing economic hardship for the urban poor and climate change impacts. This will help prevent not only future health risks but also the increased risk of urban violence and insecurity.
The new group will try to advance climate policies, even as some of its members are likely to clash. Critics say the group’s efforts won’t go far enough.
With climate change increasingly affecting food production in South Asia, it is time to focus on making food markets more resilient to climate shocks.
