Reversing ecological degradation is critical for survival of many species but will not occur without a transformational reduction in humanity’s environmental impact. Ecological civilization is a way of approaching social and ecological reform and represents a new standard of human existence that may be sustainable well into the future. However, how to achieve ecological civilization still remains a question. Landscape sustainability science, with its theoretical basis in sustainability science and landscape ecology, offers a decisive path for achieving an ecological civilization. Three concepts integral to landscape ecology will be essential for contributing to an ecological civilization: (1) linking landscape patterns with biodiversity and ecosystem processes/function across scales, (2) measuring connectivity and flows across spatially heterogeneous systems, and (3) a systems understanding of the linkages between disturbance, resilience, and recovery. Achieving an ecological civilization is within the scope of human capability, but it will require a fundamental shift in world view and cooperation amongst all actors in the human race. A key place to start is with landscapes. This editorial provides perspectives from landscape ecology and landscape sustainability science for achieving this goal.
The Anthropocene epoch marks a fundamental change in the relationship between humans and nature (Heurtebise 2017). Human manipulation and degradation of the environment has reached the point that cumulative global impacts are not only affecting our food, fiber, and water systems but also threatening people’s health and well-being (Whitmee et al. 2015). The October 2018 report from the Intergovernmental Panel on Climate Change (IPCC) warns that we risk catastrophic environmental breakdown if global warming is not kept to a maximum of 1.5 °C (IPCC 2018). Reversing climate change and other forms of ecological degradation is critical for the survival of many species, including humans (Magdoff 2011), but it will not occur without a transformational reduction in humanity’s environmental impact.
Some societies have already begun reconsidering their relationship with nature and recognizing that drastic changes to protect our ecological systems are necessary to ensure the long-term health and well-being of humans. This new way of approaching social and ecological reform has been termed ‘ecological civilization’ and represents a new standard of human existence that may be sustainable well into the future (Gare 2012; Heurtebise 2017). Ecological civilization is founded on ecological principles but also requires integrated societal reforms including economic, political, demographic, and educational transformations (Magdoff 2011; Wang 2013; Wang et al. 2014). It is a lofty goal to reform society, but given the grim trajectories forecast for climate change and other ecosystem services, it may represent our best hope for a sustainable global society.
What is ecological civilization?
While there are multiple perspectives through which ecological civilization can be viewed (e.g., values, culture, institutions, actions), above all, achieving ecological civilization requires a fundamental shift in world view from the prevailing belief that humans must exhibit dominance over nature to a more eco-centric view where humans are simply one component of a larger system. Environmental democracy, where humans are equal to all forms of life (and non-living components) on Earth with rights and responsibilities to both exploit and protect the environment, is therefore an integral component of ecological civilization (Morrison 1995). In other words, humans must play an active role in managing their relationship with nature. Currently, human appropriation of natural capital exceeds the regenerative capacity of the Earth’s life support systems (Rockström et al. 2009), creating an unsustainable situation for our landscapes. If we are to reverse the degradation occurring in ecosystems across the globe, specifically with respect to climate change and biosphere integrity (Steffen et al. 2015), humans will need to learn to meet their immediate needs in a more balanced way that ensures the maintenance of the Earth’s life-support functions to provide goods and services in the long term.
The question then becomes, how do we achieve ecological civilization? And what tools can landscape ecology and landscape sustainability science offer toward that goal?
Contributions from landscape ecology and landscape sustainability science
Achieving ecological civilization is an extremely broad goal and involves addressing a range of human–environment issues including, but not limited to: air, water, and soil pollution; remediation of contaminated areas; clean energy; climate change mitigation; food security; ecosystem health; sustainable land use; human welfare; and social justice and equity. No single field or discipline is positioned to offer a panacea of solutions or methods to address all these issues. However, certain core concepts in landscape ecology and landscape sustainability science, such as linking landscape patterns with biodiversity and ecosystem processes across scales, measuring connectivity and flows across spatially heterogeneous systems, and a spatial systems understanding, are all essential for implementing ecological civilization on the ground. We argue that ecological civilization cannot be achieved at any scale without properly managing the composition and configuration of our landscapes and balancing conservation with development in geopolitical regions. In the inaugural issue of the journal Landscape Ecology, the editor-in-chief Frank Golley (1987) established that “the task of correcting biospheric disorder is a universal activity, requiring information and insight from all. We intend that Landscape Ecology have this broad objective and that it be relevant to the problems that face mankind…” Twenty years later, in 2007, the current editor-in-chief, Jianguo (Jingle) Wu reaffirmed that “the most salient and unambiguous goal of Landscape Ecology, since day one, has been to promote interdisciplinary and integrative studies of landscapes, especially on broad scales, not only to improve our understanding of the world of landscapes, but also to provide solutions to the plethora of problems occurring in our landscapes (Wu 2007a, p. 1433).”
Within the framework of landscape studies, any ecological civilization will certainly be embedded in a landscape where the biophysical elements must have the capacity to meet current and future human needs. We highlight three concepts integral to landscape ecology that will be essential for contributing to an ecological civilization: (1) linking landscape patterns with biodiversity and ecosystem processes/function across scales, (2) measuring connectivity and flows across spatially heterogeneous systems, and (3) a systems understanding of the linkages between disturbance, resilience, and recovery.
Relationships between landscape patterns and (eco)system function
Landscape ecology is predicated on the assumption that spatial patterns influence ecological processes, and those processes, in turn, feedback to form and alter landscape patterns. A cornerstone of understanding these relationships is the quantification of spatial patterns using landscape metrics derived from remote sensing and geographic information systems (GIS) data, with key insights gained in the past decades (Gustafson 2019). However, while the focus in landscape ecology has had a prominent emphasis on ecosystem processes and functioning (but see Naveh and Lieberman 1984), there is growing recognition that land systems (and therefore landscapes) are coupled human-natural systems. During the past 30 years, landscape ecology has increasingly adopted a more holistic, social-ecological approach to understanding the relationship between pattern and process (Wu 2017).
One way in which this holistic approach is occurring is through the adaptation of landscape metrics to measure social ecosystem service areas. For example, De Vreese et al. (2016) demonstrated how social landscape metrics measuring abundance, diversity, richness, risk, and rarity of ecosystem services can be used to capture and integrate social perspectives into landscape analyses. While debates will continue around the relevance of these pattern metrics, and, more generally, the models used to compute them (Frazier and Kedron 2017), the reality is that monitoring global changes that affect and are affected by an ecological civilization requires broad-scale Earth observation. The tools and techniques from landscape ecology are critical for this task.
Measuring connectivity and flows across spatially explicit systems
The central tenet of landscape ecology—that landscape patterns and ecological processes are intertwined—means that landscape ecologists have a long tradition of measuring connectivity (through spatial pattern metrics) and energy flows across landscapes. Recent research highlights the need to connect ecosystem services with beneficiaries (Bagstad et al. 2013), which will prove critical in an ecological civilization. However, as related to the points above, the integration of social aspects into landscape-wide studies is critical. Specifically, political and administrative boundaries often serve as barriers that constrain environmental flows (e.g., walls and fences prevent animal movement), but they also prevent the unrestrained flow of practices and ideas and may ultimately set the spatial extent for social and cultural analyses of ecological civilization practices. Studies of ecological civilization will almost certainly compound the search for appropriate observation, experimental, modeling, and policy scales (Wu 2007b), which is also central to landscape ecology.
A systems approach to disturbance, resilience, and recovery
Landscape ecologists take a holistic view of the interactions between landscape elements, the ecological system, and organisms—both human and non-human. Furthermore, the field is concerned with how these integrated systems are influenced by human interventions. Perhaps the most salient example of this systems approach is through landscape ecological work related to disturbance, resilience, and recovery (e.g., Turner et al. 2013). In her Robert H. MacArthur award lecture titled “Disturbance and landscape dynamics in a changing world,” Turner (2010) stressed that the effects of disturbances can persist for decades or centuries. Furthermore, research has shown that systems may not be resilient to novel disturbances, despite a record of past resilience. Looking to the future, landscape ecologists have already begun to focus on reducing vulnerable populations, examining the relationships between anthropogenic land cover change and disturbance patterns, and asking how disturbances will interact with climate changes and feedback to global cycles.
While disturbances have traditionally been defined as relatively discrete events (e.g., several hours to several weeks) (Turner et al. 2001), ‘slow onset disasters’ such as drought, climate change, desertification, and environmental degradation, also disrupt ecosystems, populations (both human and ecological), and communities. Human-induced climate change may already be the largest planetary disturbance ever orchestrated by humans, and any ecological civilization will be embedded in a system where the effects of climate change will be present. How long these effects will persist and whether or not they can be reversed over time is yet to be seen. However, the foundational understanding of disturbances gained through a systems landscape ecology approach will be critical.
The role of landscape sustainability science
To achieve this new level of civilization, we first need a deeper understanding of how to design and manage sustainable landscapes that provide long-term ecosystem services essential for human well-being. For this purpose, LSS emphasizes the need to identify landscape-specific ecosystem services essential for human well-being. Specifically, Wu (2013) addresses four basic questions: “what is to be sustained, what is to be developed, how are these two aspects related to each other, and on what scales should all these be considered?” With the goal of achieving an ecological civilization, we should also be asking ourselves: what is to be restored? Yet, before degraded landscapes can offer such spaces, it will be imperative for society to identify the key elements that need improving.
The concept of forest landscape restoration offers an example of how LSS can provide a path to eco-civilization. Forest landscape restoration is a planned process aimed at recovering ecological functionality while simultaneously enhancing human well-being at the landscape level (Mansourian et al. 2005; Maginnis et al. 2007). The process is focused on recovering the capacity of the entire landscape—not just a habitat or ecosystem—from a holistic perspective, which embodies the close interrelationships between the components of LSS, such as biodiversity, ecosystem processes, ecosystem services and human well-being. Additionally, forest landscape restoration seeks to redefine the relationship between human and nature by implementing innovative practices aimed at restoring ecological and socio-economic processes that benefit local community and stakeholder groups. As such, forest landscape restoration provides a model for the process needed to help society move toward ecological civilization.
Areas for measurable success
Human well-being is a key focus of LSS and one where we can measure progress toward an ecological civilization. One of the most salient features that characterize human civilization during the past millennium is accelerating urbanization (Wu et al. 2014), which is impacting human well-being in varied ways (Yang et al. 2018). Wu (2014) points out that human well-being depends fundamentally on ecosystem services, requiring concerted ecological, economic, and social actions in response to changes within and beyond our landscapes. Specifically, measuring improvements to human health across landscapes can be an indicator of the sustainable balance between human needs and nature. Of the 17 United Nations’ Sustainable Development Goals, Goal #3 ‘Good Health and Well-Being’ requires balancing environmental protection (Goals 6, 7, 11, 12, 13, 14, 15) with social and economic growth (Goals 1, 4, 5, 9, 10), and thus encapsulates many of the most important building blocks for an ecological civilization. The past two decades have seen a rapid increase of studies associating landscape patterns with human health and disease spreading, leading to new research areas known as geohealth (Dummer 2008), landscape epidemiology (e.g., Cumming et al. 2015), and spatial lifecourse epidemiology (Jia 2019). A number of broad-scale studies have demonstrated the success of applying spatial technologies, such as GIS, remote sensing, and landscape modeling, to aid in achieving the Millennium Development Goals and Sustainable Development Goals (Jia et al. 2016; Gao and Bryan 2017) and human and planetary health (Bohnet et al. 2011; Jia et al. 2015; Whitmee et al. 2015; Jia and Stein 2017; Opdam et al. 2018; Sun et al. 2018).
Bryan et al. (2018) synthesized China’s efforts over the past 20 years to arrest and reverse an accelerating decline in the environmental and economic sustainability of its rural environments. Through a portfolio of major programs, China’s central government invested over US$350 billion in implementing sustainability intervention across nearly two-thirds of China’s land area. The programs were successful in reducing poverty and hunger, deforestation, soil erosion and sedimentation, desertification and dust storms, and biodiversity decline, and realigning China’s rural areas on a path more consistent with ecological civilization. A key part of the success of this massive intervention was an evidence-based, targeted, coordinated, and integrated approach at-scale, which anticipated the trade-offs that are common in land systems. For example, interventions were aimed at breaking the poverty and environmental degradation trap—a vicious cycle where increasing poor people apply more and more pressure on the local environment to produce food and income, which degrades the environment further and, makes them poorer still. As another example, reducing deforestation and reforesting large areas of land minimized the impact on timber supply and agricultural production through parallel and complementary programs aimed at boosting timber supply and food production. China’s sustainability programs implemented many principles that we now recognize as part of landscape ecology, systems dynamics, and sustainability science.
History has witnessed the progression of human development from primitive civilizations to agrarian societies to the eventual transition into industrial civilizations. As countries compete to achieve higher and higher levels of prosperity at the cost of the environment, the concept of ecological civilization provides a timely wake-up call. Reversing the trends of industrial civilizations and rolling back the clock on environmental degradation through processes such as forest and grassland landscape restoration will continue to provide measures of a successful transition to ecological civilization.
Implementing this concept will not be an easy task though and will require fundamental changes across society. In addition to shifting values and cultures, there must be action at the organizational and institutional levels to promote these shifting ideas allowing them to be realized through formal and informal institutional arrangements. As such, achieving an ecological civilization is a long-term and bold goal for human social development, and there is a long way to go before we realize such a society. First, humans’ role in the earth ecosystem need to be reestablished and activities need to be reconsidered from the standpoint of integral ecosystem management. Second, individuals will need to redefine personal behaviors with respect to conservation and environmental protection. Third, working toward an ecological civilization requires input and involvement from all corners of society including economic, cultural, political, religious, environmental, etc. Achieving an ecological civilization is within the scope of human capability, but it will require a fundamental shift in world view and cooperation amongst all actors in the human race. We need to start with our landscapes!
