Think of the entire global human enterprise as a system − what Earth system scientists are beginning to call the technosphere.  It consists of all the material artifacts and energy flows associated with our global high technology civilization, as well as all the social bonds and institutions that tie us together.  A high degree of connectivity is evident in the technosphere (Figure 1), and it is worth asking if more connectivity (e.g., a stronger United Nations) or less connectivity (e.g., effects of anti-globalization) would help in the struggle for global sustainability.

Systems are often specified in terms of parts and wholes, and in terms of interactions between the parts that help maintain the whole.  The quantity and nature of these within-system connections have long been of interest to systems theorists because of their influence on system stability.  The connectivity concept offers a lens through which to view technosphere structure and function.

In the ecological literature, (eco)system connectivity has two aspects.  One is geographic (2-dimensional) – as in corridors across a landscape that allow movement of animals or dispersal of seeds.  High connectivity is important because, for instance, after a disturbance such as fire, early successional species must find their way to the disturbed patch.

The second aspect of ecosystem connectivity relates to the way processes are coupled.  In a highly connected forest ecosystem, the processes of decomposition (which releases nutrients) and net primary production (which requires nutrient uptake) are coupled by way of a network of fine roots or mycorrhizae.  In a weakly connected tree plantation, where a significant proportion of nutrients are provided by fertilizer, that coupling is missing.  High connectivity of processes usually means more effective system regulation.

In the technosphere, geographic connectivity is maintained by the transportation and telecommunications infrastructure.  Process-based connectivity relies on coupling between sources and sinks of energy, materials, information, and money. 

Technosphere connectivity has grown increasingly dense over time (Figure 1) with a corresponding rise in technosphere mass and energy throughput.  All that global connectivity has helped raise standards of living for billions of people.  But the technosphere is showing signs of self-destructiveness, and it is worth asking if it is in any sense underconnected or overconnected.

Ecologist C.S. Hollings has argued that late successional ecosystems become overconnected.  In his panarchy model for ecosystem development, a four-stage cycle (Figure 2) begins with a catastrophic disturbance (Release phase).  The disturbance stimulates decomposition of dead organic matter and frees up resources for colonizing species that seed in and rapidly accumulate biomass (Reorganization Phase).  As the ecosystem fills in (Exploitation or Growth Phase), the connectivity increases (note the x-axis).  In contrast to earlier theories of ecosystem dynamics, Hollings suggested that ever increasing ecosystem connectivity may ultimately be destabilizing because nutrients get locked up in biomass, and a high density of organisms means strong competition that stresses the organisms and makes them vulnerable to disturbance (Conservation Phase).  Eventually, the stressed condition of the biota allows another major disturbance, such as an insect outbreak (Release Phase), that sweeps across the ecosystem and restarts the panarchy cycle.  The Reorganization phase is a period of low connectivity, leaving the ecosystem susceptible to degradation.

The technosphere system is like an ecosystem in having a throughput of energy (mostly fossil fuel) and a turnover of its components.  It has certainly gone through a growth phase (often referred to as the Great Acceleration) and is now accumulating connections rapidly as it matures.  Let’s place it somewhere between the Exploration and Conservation phases in Figure 2.  It might be underconnected in the sense of weak links between different geographic areas (e.g., in the face of global scale problems like climate change) and limited coupling of critical processes (e.g.,   mobile phone manufacturing and mobile phone recycling).  The opposite concern is that it may at some point become overconnected and vulnerable to a major disturbance. 

Let’s examine ways in which the technosphere could be considered underconnected.

1.  An underconnected technosphere is one in which global scale coordination is unable to meet the challenges of Earth system maintenance.  Lack of connections allows global scale problems to escape technosphere control.  The situation with global climate change evokes this sort of underconnection.  In broad terms, we have inadequate institutions for global environmental governance (not to mention global economic governance).  The shambolic global response to COVID-19 is also indicative of underconnection; a better coordinated global vaccination program would have been in the best interest of everyone.

2.  The technosphere is causing massive disruption of the biosphere and Earth’s climate.  These impacts on the Earth system are associated with failure to fully recycle technosphere “waste products”, e.g., the production of carbon dioxide by fossil fuel combustion is not connected to the removal of carbon dioxide from the atmosphere by some other industrial process.

3.  A renewable energy revolution is clearly needed to mitigate climate change, but the sources of renewable energy (e.g., wind and solar) may not be co-located with the demand for energy (urban areas).  Hence, a more robust grid (nationally and internationally) for distribution of electricity is required (along with other energy infrastructure upgrades).

4.  We think of the global Internet as foundational for global connectivity.  And, in fact, the Internet facilitates the kind of global coordination that is needed to address global environmental change issues that threaten the technosphere.  However, nations such as China and Russia have built national Internet firewalls that prevent their citizens from freely accessing the Internet.  That kind of fence raising promotes nationalism, but not the planetary citizenship we need to create a sustainable future.

The case for an overconnected technosphere is less compelling.  The rapid spread of the 2007-2008 financial crisis around the planet is suggestive of fragility in the global economy.  And the crush of 7.8 billion people striving for a high quality of life is contributing to widespread stress in the biosphere (upon which the technosphere depends).  Ironically, solving these problems may require greater international connectivity.

We are still in the early stages of technosphere evolution, and my sense is that greater global connectivity is desirable.  With regard to the global environment, we are in dire need of 1) a well-connected circular economy that recycles all manufactured products, and 2) new international institutions for global environmental governance that coordinate monitoring, assessments, adaptation, and mitigation of global environmental change problems.  The anti-globalization movement calls for less connectivity but the proliferation of global scale problems points to the need for more connectivity.

A Systems Theory View of the Emerging Planetary Socio-ecological System

David P. Turner / May 6, 2021

A Great Transition is hopefully underway − from humanity’s current chaotic rush towards environmental disaster, to a more ordered Earth system in which the global human enterprise (the technosphere) becomes sustainable.  However, achieving the necessary planetary scale organization of the human enterprise will be a challenge. 

The discipline of systems theory offers insights into how new forms of order emerge, and here I will introduce two of its concepts − holarchy and metasystem transition − as they relate to the process of creating a sustainable planetary civilization.

The technosphere is commonly presented as a whole.  I like to draw the analogy between the technosphere and the biosphere: both use a steady flow of energy to maintain and build order.  Just as the biosphere evolved by way of biological evolution from microbes to a verdant layer of high biodiversity ecosystems cloaking the planet, the technosphere is evolving by way of cultural evolution into a ubiquitous layer of machines, artifacts, cities, and communication networks that likewise straddles the planet.

This formulation of the technosphere as a global scale entity is a glossy overview that allows one to make the point that the growth of the technosphere has altered the Earth system in ways that are toxic to some components of the biosphere, and indeed to the technosphere itself.  Technosphere emissions of greenhouse gases leading to rapid climate change is the iconic example.

The view of the Earth system as composed of interacting spheres (geosphere, atmosphere, hydrosphere, biosphere, cryosphere, technosphere) is also useful for imagining and modeling the feedbacks that regulate Earth system dynamics, e.g., the positive feedback of the cryosphere to climate warming in the atmosphere, or the negative feedback to climate warming by way of the geosphere-based rock weathering thermostat.

But systems theory offers another lens through which to examine the technosphere and its relationship to the contemporary Earth system.  This view relies on further disaggregation.

Systems theory is a discipline that studies the origin and maintenance of order.  The objects of study are systems − functional entities that can be analyzed in terms of parts and wholes. 

Complex systems are often structured as holarchies , i.e., having multiple levels of organization.  Complexity in general refers to linkages among entities at a range of spatial and temporal scales, e.g., a city is more complex than a household. 

Like the more familiar hierarchy (e.g., a military organization), there are levels in a holarchy; lower levels are functional parts of the levels above.  The entities (holons) at each level are “wholes” relative to the level below but “parts” relative to the level above.  The difference between holarchy and hierarchy lies in representation of both upward and downward causation in a holarchy compared to primary concern with downward-oriented control in a hierarchy.

Let’s consider the environmental management aspect of the Earth system as a holarchy (Table 1). 

Table 1.  Levels in a planetary natural resources management holarchy.  The Integrating Factors refer to how the components within a holon interact.

The emphasis in this management-oriented holarchy is on holons that consist of coupled biophysical and sociotechnical components.  Environmental sociologists term a holon of this type a socio-ecological system (SES) (Figure 1).  In an SES, stakeholders coordinate amongst themselves in management of natural resources.

At the base of the Earth system SES holarchy (Figure 2) are managed properties, such as a farm or wildlife refuge, where humans and machines manipulate the biophysical environment to produce ecosystem services such as food production and biodiversity conservation.

A step up, at the landscape level, are mosaics of rural and urban lands.  A town with parks and an extensive greenbelt, or a national forest in the U.S., which is managed for wood production as well as water quality and other ecosystem services, are sample landscapes.  Disturbances within a landscape, such as wildfire on the Biophysical side or a change in ownership on the Sociotechnical side, can be absorbed and repaired by resources elsewhere in the landscape (e.g., reseeding a forest stand after a fire).

At the ecoregion level, there is a characteristic climate, topography, biota, and culture.  My own ecoregion, the Pacific Northwest in western North America, is oriented around the Cascades Mountains, coniferous forests, high winter precipitation, and an economy that includes forestry, fishing, and tourism.  These features help define optimal natural resources management practices.  A significant challenge at the ecoregion level is integration of management at the property and landscape scales with management of the ecoregion.  Ecoregions interact in the sense of providing goods and services to each other, as well as collaborating on management of larger scale resources such as river basin hydrology.

The national level is somewhat arbitrary as a biophysical unit, but the sociotechnical realm is significantly partitioned along national borders, so the nation is in effect a clear level in our SES holarchy.  Nations have, in principle, well organized regulatory and management authorities that aim for a sustainable biophysical environment as well as a stable and prosperous socioeconomic environment.

At the planetary level, the sociotechnical aim is to manage the global biophysical commons − the atmosphere and oceans − and coordinate across nations on transborder issues like conservation of biodiversity.  That would mean agreements on policies to limit greenhouse gas emissions, reduce air and water pollution, and manage open ocean fisheries.

A strong global environmental governance infrastructure is needed at the planetary level to ensure a sustainable relationship of the technosphere to the rest of the Earth system.

But what we have now at the global scale is a weakly developed array of intergovernmental organizations (e.g., the United Nations Environmental Program), transnational corporations that heavily impact the global environment, and international nongovernmental organizations like Greenpeace.  We do not have a fully realized planetary level of environmental governance. 

The systems theory term for emergence of a new level in a holarchy is “metasystem transition”.  This process involves an increasing degree of interaction and interdependency among the constituent holons (nations in this case).  Eventually, positive and negative feedback relationships are established that promote coexistence and cooperation.  The origin of the European Union is a relevant case study of a metasystem transition in the geopolitical realm. 

Resistance to planetary scale management is understandable – notably because nations fear losing sovereignty.  Less developed nations worry about external imposition of constraints on their economic development that may be unjust considering the global history of natural resource use.  Working through these political issues is fraught with complications, thus the process would benefit from focused institutions.  Global environmental governance researchers have proposed creation of a United Nations-based World Environment Organization, which would coordinate building environmental management agreements with follow through monitoring and enforcement. 

A key driver for the success of planetary-level SES integration is that each nation is faced with environmental problems, like climate change, that it cannot address on its own.  Survival will require a new level of integration with its cohort of national-level holons.  Possibly, progress in collaboratively addressing global environmental threats like climate change could even lead to further progress in collaboratively addressing global geopolitical threats like the proliferation of nuclear weapons.
