<div type="abstract" xml:lang="en">
<p>Cities are rapidly increasing in importance as a major factor shaping the Earth system, and therefore, must take corresponding responsibility. With currently over half the world’s population, cities are supported by resources originating from primarily rural regions often located around the world far distant from the urban loci of use. The sustainability of a city can no longer be considered in isolation from the sustainability of human and natural resources it uses from proximal or distant regions, or the combined resource use and impacts of cities globally. The world’s multiple and complex environmental and social challenges require interconnected solutions and coordinated governance approaches to planetary stewardship. We suggest that a key component of planetary stewardship is a global system of cities that develop sustainable processes and policies in concert with its non-urban areas. The potential for cities to cooperate as a system and with rural connectivity could increase their capacity to effect change and foster stewardship at the planetary scale and also increase their resource security.</p>

<abstract id="Abs1">
<p>Cities are rapidly increasing in importance as a major factor shaping the Earth system, and therefore, must take corresponding responsibility. With currently over half the world’s population, cities are supported by resources originating from primarily rural regions often located around the world far distant from the urban loci of use. The sustainability of a city can no longer be considered in isolation from the sustainability of human and natural resources it uses from proximal or distant regions, or the combined resource use and impacts of cities globally. The world’s multiple and complex environmental and social challenges require interconnected solutions and coordinated governance approaches to planetary stewardship. We suggest that a key component of planetary stewardship is a global system of cities that develop sustainable processes and policies in concert with its non-urban areas. The potential for cities to cooperate as a system and with rural connectivity could increase their capacity to effect change and foster stewardship at the planetary scale and also increase their resource security.</p>

<title>Introduction</title>
<p>Human activities now rival or exceed biogeophysical drivers in transforming the planet to the extent that this time in history warrants an epoch of its own, increasingly referred to as “the Anthropocene” (Crutzen and Stoermer
<xref ref-type="bibr" rid="CR9">2000</xref>
; Crutzen
<xref ref-type="bibr" rid="CR8">2002</xref>
; Steffen et al.
<xref ref-type="bibr" rid="CR33">2011</xref>
). Increasing size and urban concentration of world population, coupled with changing lifestyles and associated consumption patterns, have led to unprecedented resource use and waste generation during the twentieth century. This expanding level of demand requires a portfolio of responses that address environmental, social, and economic issues at the planetary scale. The interconnected nature of problems, the multiple scales and rates involved, and the geopolitical constellations make this a formidable yet urgent challenge.</p>
<p>Research approaches as well as governance responses to date have focused largely on single issues (e.g., air pollution, population, climate, water, etc.) and on the search for solutions and treaties that often do not match the magnitude of the problems. In contrast, many issues are interconnected, the drivers and effects cross many space and time scales, and encompass environmental and socio-economic dimensions. In addition, political imperatives and difficulties in assigning and quantifying responsibilities have contributed to lack of action and slow progress.</p>
<p>Here, we build on and extend previous thinking on earth and planetary stewardship (e.g., Steffen et al.
<xref ref-type="bibr" rid="CR32">2004</xref>
,
<xref ref-type="bibr" rid="CR33">2011</xref>
; Chapin et al.
<xref ref-type="bibr" rid="CR7">2011</xref>
). We define planetary stewardship as the active shaping of trajectories of change on the planet, that integrates across scales from local to global, to enhance the combined sustainability of human well-being and the planet’s ecosystems and non-living resources. To support planetary stewardship a coordinated polycentric governance approach is required that is informed by a deeper understanding of the complex, multi-scalar, and interconnected nature of today’s global environmental challenges. Given the increasing importance of urbanization and concomitant pressure on resources, we contend that one of the necessary elements for achieving stewardship is the sustainability of the emerging global system of cities, including their hinterlands.</p>

<sec id="Sec2">
<title>The Urban Dimension</title>
<p>Contemporary urbanization differs from the past in its rate, scale, location, and form (Seto et al.
<xref ref-type="bibr" rid="CR28">2010</xref>
). In 1800, when the world population hovered around 1000 million people, the only city with more than a million inhabitants was Beijing (Chandler
<xref ref-type="bibr" rid="CR6">1987</xref>
). By 1900, about 16 cities had crossed this threshold, a number that swelled to 200 at the beginning of this millennium. If the trend continues, by 2025 there will be around 600 cities worldwide with populations of a million or more. By 2100, the global population is projected to be 3000 million more than today, with 70–90 % of people living in urban regions (UN
<xref ref-type="bibr" rid="CR35">2011</xref>
). This increase in urban population is projected to be not only from global population increase but also from immigration from rural areas.</p>
<p>Currently, more than half of the global population lives in urban areas (UN
<xref ref-type="bibr" rid="CR35">2011</xref>
), although urban areas account for only about 2 % of global land surface (Akbari et al.
<xref ref-type="bibr" rid="CR1">2009</xref>
). These are global centers of production and consumption (Seto et al.
<xref ref-type="bibr" rid="CR28">2010</xref>
). By some accounts, more than 90 % of the world’s gross domestic product (GDP) is produced in urban regions (Gutman
<xref ref-type="bibr" rid="CR19">2007</xref>
). Consequently, urban regions, in both developed and developing countries, use a large amount of energy and other resources (Dhakal
<xref ref-type="bibr" rid="CR12">2009</xref>
). Approximately, 70 % of energy-related carbon emissions, 60 % of residential water use, and 76 % of wood used for industrial purposes is attributed to cities globally (Brown
<xref ref-type="bibr" rid="CR5">2001</xref>
; World Energy Outlook
<xref ref-type="bibr" rid="CR37">2008</xref>
).</p>
</sec>
<sec id="Sec3">
<title>Global Flows and Interconnected Issues</title>
<p>With increasing globalization, materials and energy are drawn in great quantities from all over the world—often from large distances to the primarily urban locus of consumption and waste generation. Such distal flows and dependencies provide a global perspective of the more traditional view of the urban–rural nexus. For example, fish meal is imported from marine ecosystems worldwide to feed shrimps farmed in ponds in Thailand which are then exported to primarily urban global markets (Deutsch et al.
<xref ref-type="bibr" rid="CR11">2007</xref>
). Folke et al. (
<xref ref-type="bibr" rid="CR16">1997</xref>
) estimated that people living in 744 large cities worldwide appropriate ~25 % of the globally available shelf, coastal, and upwelling areas for their seafood consumption. The connection of urban regions to globally dispersed areas of terrestrial production is illustrated by the global, spatial analysis of the link between plant production required for food, feed, fiber, and bioenergy supply and the location of the consumption of these products (Erb et al.
<xref ref-type="bibr" rid="CR13">2009</xref>
). It is not only land use related to the production but also implications of the water used to produce the food that is of concern. Globally, the volume of virtual water “embodied” in international food trade more than doubled in the period from 1986 to 2007 (Dalin et al.
<xref ref-type="bibr" rid="CR10">2012</xref>
).</p>
<p>Studies of the urban metabolism of specific cities have documented the inflows, transformations, and outflows of resources and wastes (e.g., Warren-Rhodes and Koenig
<xref ref-type="bibr" rid="CR36">2001</xref>
; Kennedy et al.
<xref ref-type="bibr" rid="CR20">2007</xref>
). Ecological footprints of cities provide another approach. For example, an ecological footprint analysis of London indicated that around 80 % of food consumed in London is imported from other countries (Best Foot Forward Ltd.
<xref ref-type="bibr" rid="CR3">2002</xref>
cited in Satterthwaite
<xref ref-type="bibr" rid="CR27">2011</xref>
). However, the geographic distribution of resource extraction and waste generation by individual cities is not yet available, although insights are provided by analyses of the global reach of resource use by highly urbanized countries such as The Netherlands and Japan. An analysis by Rood et al. (
<xref ref-type="bibr" rid="CR25">2004</xref>
) documented the global distribution of land used by The Netherlands (Fig. 
<xref rid="Fig1" ref-type="fig">1</xref>
). To supply the food and fiber needs of The Netherlands’ population, required an area four times larger than this small and highly urbanized country. This emphasizes the dependence on rural land and communities in other countries. The distal flows and connections between urban and non-urban regions are an important driver of land-use change (Seto et al.
<xref ref-type="bibr" rid="CR29">2012</xref>
). Some countries and corporations are now even attempting to assure their food and energy security via land lease arrangements in other countries (e.g., in Africa; Mbow
<xref ref-type="bibr" rid="CR21">2010</xref>
), which has impacts on land use as well as potentially negative and positive implications for local livelihoods.

</fig>
</p>
<p>As with many issues, land use does not stand alone but rather is interrelated with the use of other resources, including water and nitrogen. This is illustrated by the global analysis of the use of these resources in livestock production and trade (Galloway et al.
<xref ref-type="bibr" rid="CR17">2007</xref>
). For example, the consumption of meat (pork and chicken) in highly urbanized Japan is supported by the use in other countries (e.g., Brazil, USA, China) of over 2 million ha of land mainly for feed crop production, 3500 million m
<sup>3</sup>
of water for irrigation and processing, etc., and 2.2 × 10
<sup>5</sup>
 metric tons of N fertilizer which contributes to aquatic eutrophication.</p>
<p>As the global urban population and its consumption increase, it is not only the sheer physical use of the planet’s resources, primarily from the hinterlands, that is of concern, but also the impacts on society and the environment. These impacts occur at many scales and the critical thresholds in many cases are crossed first at local and regional scales nearer the locus of resource use—with more immediate social and biogeophysical repercussions for regional food supply, water pollution as noted above, migration, social inequality, etc. For example, with increasing urbanization, emigration from rural areas to urban centers may not only erode rural communities but also continue to shift the focus of governments away from rural areas; this can lead to poor governance of the regions which are critical to the successful delivery of resource flows and ecosystem services to urban areas (Stafford Smith and Cribb
<xref ref-type="bibr" rid="CR31">2009</xref>
).</p>
<p>Given the complexity of systemic environmental and social issues now facing us, we should seek solutions that have positive, multiple synergetic effects and which, in combination, address the three dimensions of sustainability: social, economic, and environmental. Air pollution in many urban regions, including increasingly in Asia and Africa, poses major human and environmental health risks. At the same time a number of air pollutants also affect climate. To address the interrelated issues of climate and air pollution, Shindell et al. (
<xref ref-type="bibr" rid="CR30">2012</xref>
) identified a suite of pollution-control measures. If these were to be implemented simultaneously with ambitious CO
<sub>2</sub>
emission reductions, they suggest that global warming might be limited to <2 °C during the coming 60 years, with substantial direct co-benefits for human health and improved crop productivity.</p>
<p>Recent studies suggest that global food supply would need to roughly double by 2050 to meet the food and dietary changes of the primarily (~70 %) urban global population (Royal Society of London
<xref ref-type="bibr" rid="CR26">2009</xref>
; Godfray et al.
<xref ref-type="bibr" rid="CR18">2010</xref>
; UN
<xref ref-type="bibr" rid="CR35">2011</xref>
). Doubling global food supply without extensive additional environmental degradation to non-urban areas presents a major challenge (Foley et al.
<xref ref-type="bibr" rid="CR15">2011</xref>
; Tilman et al.
<xref ref-type="bibr" rid="CR34">2011</xref>
). Foley et al. (
<xref ref-type="bibr" rid="CR15">2011</xref>
) suggested an approach to double food supply using a combination of measures to decrease the yield gap, decrease waste, and decrease meat consumption primarily in developed countries, while at the same time protecting key carbon sequestering ecosystems, biodiversity, and water quality. International co-operation in the form of technology transfer between rich and poor regions could be a key component of meeting food demands and at the same time reduce environmental degradation (Tilman et al.
<xref ref-type="bibr" rid="CR34">2011</xref>
). Technology transfer resulting in moderate intensification in croplands in under yielding nations could reduce, by 2050, land clearing by 80 %, land use-related GHG emissions by 1 Pg CO

, and N pollution of land and water.</p>
<p>In summary, the sustainability of a city can no longer be thought of in isolation from the combined resource use and impacts of cities globally. Urban areas are supported by human and natural resources often drawn from far distant regions. Multiple cities often draw on the same regions for their resource requirements. Therefore, interconnected solutions and new governance systems that take into account the planet’s limited resources are needed.</p>
</sec>
<sec id="Sec4">
<title>Bringing Stewardship to Practice</title>
<p>Planetary stewardship must take into account the planet’s limited resources, interconnected issues, increasing urban population, and the reliance of urban areas on rural resources and their communities. Urban and rural are no longer useful boundaries to make with regard to planetary stewardship. It has become clear that urban activities drive much of the global changes we see, whether in energy use, resource depletion, land-use change, etc. Yet, we do not have adequate information on resource flows and their impacts or a conceptual framework for governance that takes into consideration the combined use of resources by cities and their interconnections with rural areas. At local scales efforts have been made to bridge the urban–rural divide and integrate social and ecological systems in regional urban planning (e.g., Alfsen et al.
<xref ref-type="bibr" rid="CR2">2011</xref>
). But how to address the planetary scale challenges?</p>
<p>Many recent analyses have questioned the benefits of an exclusive reliance on a single global governance solution for tackling climate change and other environmental and socio-economic challenges (Ostrom et al.
<xref ref-type="bibr" rid="CR24">1961</xref>
; Biermann
<xref ref-type="bibr" rid="CR4">2010</xref>
; Ostrom
<xref ref-type="bibr" rid="CR23">2010</xref>
; Young
<xref ref-type="bibr" rid="CR38">2011</xref>
). The diverse and interconnected issues facing the planet warrant a cross-scalar, multi-agent approach to planetary stewardship. Because urban regions will likely remain key loci of intensive processing of global resources, they must take corresponding responsibility and that responsibility must connect to rural regions. In addition, the sustainability of an individual city must be seen within the context of the combined resource use by cities globally (Fig. 
<xref rid="Fig2" ref-type="fig">2</xref>
).
<fig id="Fig2">
<label>Fig. 2</label>
<caption>
<p>A global system of cities cooperating with rural regions for sustainable management of planetary resources</p>
</caption>
<graphic xlink:href="13280_2012_353_Fig2_HTML" id="MO2"></graphic>
</fig>
</p>
<p>Collaboration across a global system of cities could and should provide a new component of a framework to manage sustainable resource chains and their impacts (Fig. 
<xref rid="Fig2" ref-type="fig">2</xref>
). The geographical and cultural diversity within a system of cities can provide powerful support for creative action (Ernstson et al.
<xref ref-type="bibr" rid="CR14">2010</xref>
; Olsson and Galaz
<xref ref-type="bibr" rid="CR22">2012</xref>
). However, sustainability practices and policies for a global system of cities must consider the urban teleconnections and therefore must be developed with a two-way dialog with distal rural areas. The potential for cities to cooperate as a system and with rural connectivity—as a positive component of the Anthropocene—could not only increase their capacity to effect change and foster stewardship at the planetary scale but also increase their resource security.</p>
<p>Cities are already engaging in cooperative partnerships and beginning to take an active role in the management of resources and impacts on the regional or even global scale. For example, complementary to national and international efforts to curb greenhouse gases, initiatives have emerged such as the C40 Cities Climate Leadership Group and the World Mayor’s Council on Climate Change. However, additional cooperative partnerships among urban and non-urban places are needed and these must extend to other global environmental issues, and address their interconnections and impacts on our planet. A global system of cities must also operate within a framework of other actors such as national, regional and local governments, multinational corporations, and civil society (Fig. 
<xref rid="Fig3" ref-type="fig">3</xref>
). Each of these actors has important roles to play in managing planetary resources.

</p>
<p>How to move forward given the magnitude and the complexity of the challenge, and insufficient knowledge, tools, and experience? Planetary stewardship of the sort proposed in this article is essentially untested. Experimental case studies that include cities across a range of geographic, development, and cultural settings are an essential first step. In addition, we suggest three priority areas of user-engaged research that are needed to bring planetary stewardship to practice. Co-design, co-production, and analysis of results by scholars, professionals, decision makers, and civil society should be a component in each of these.
<list list-type="order">
<list-item>
<p>Resources: Sustainable solutions require a deeper understanding of the geographic distribution of the planet’s resources, flows, interconnected uses, resultant wastes and stressors, and environmental and social impacts. The response of the social-ecological system to shocks (e.g., hurricanes, earthquakes, severe droughts) must be a component of such studies (Chapin et al.
<xref ref-type="bibr" rid="CR7">2011</xref>
). Studies should be developed within a fuller cost-accounting context considering the externalities of rural production and urban use. Building on existing and new knowledge a suite of user-friendly tools that allow analysis of future scenarios of resource use and impacts within a societal context should be developed.</p>
</list-item>
<list-item>
<p>Governance: We need empirical data on, for example, how the growing power and centrality of cities is appropriately connected to rural areas in terms of their empowerment and subsidiarity. This requires research on multi-dimensional networks that encompass different cities as well as the governance units along resource chains. Some specific questions to address include: what can facilitate better coordination between governance units at the same as well as different levels? How can polycentric governance increase resilience while at the same time minimizing the transaction and communication/coordination costs?</p>
</list-item>
<list-item>
<p>Information: Continuously updated information about coupled social-ecological systems is critical to achieve stewardship. Modern information technologies can support a system for monitoring and analysis of planetary conditions and support decision making at all levels. Putting this into practice will require sustainability services—an extension of the concept of the emerging climate services—to provide easy access to the data and analysis tools and a shared knowledge platform for communities of practice. At the same time, experimentation with novel models of governance will generate a pool of experience to draw on depending on the physical and socio-economic context.</p>
</list-item>
</list>
</p>
<p>Planetary stewardship that is mindful of society and the planet is the challenge of the Anthropocene. Effective stewardship must consider the multi-scale, interconnected resource chains, and their diverse actors. Urban regions must take an increased responsibility for motivating and implementing solutions that take into account their profound connections with and impacts on the rest of the planet.</p>
