What is the Anthropocene? Human and natural?
Just as the Anthropocene begins? One hundred
years ago, the postcard from the Northeast had a
smoking factory.

So long as we do not, through thinking,
experience what is, we can never belong to what
will be. The flight into tradition, out of a
combination of humility and presumption, can
bring about nothing in itself other than self
deception and blindness in relation to the
historical moment.

after the 1970s. In the U.S., total water use
peaked around 1980 and had declined by a tenth as
of 1995, despite simultaneous addition of some 40
million people.

What is Industrial Ecology?
  • Industrial ecology is the multidisciplinary study
    of industrial and economic systems and their
    linkages with fundamental natural systems. It
    incorporates, among other things, research and
    data involving energy supply and use, new
    materials, new technologies and technological
    systems, basic sciences, economics, law,
    management and social sciences.

Framework and Implementation (Upper Saddle River
Prentice-Hall), p 40.
11
What is Industrial Ecology?
  • The word industrial by and large, it is meant to
    apply to all kinds of human activities that
    relate to material and energy stocks and flows,
    including agricultural, manufacturing,
    transportation, mining, fishing, and service
    industries, not just factories. It includes not
    just production but consumer behavior and
    consumption systems.

Earth Systems Engineering and Management
  • Earth Systems Engineering and Management is the
    capability to design, engineer, and manage,
    through dialog and continual feedback, integrated
    built/human/natural systems that achieve the
    multivariate and sometimes mutually exclusive
    goals and desires of humanity, including at the
    least personal, social, economic, technological,
    and environmental dimensions, within the
    constraints imposed by the states and dynamics of
    existing complex adaptive systems.

  • Step 2 Capture emissions (carbon sequestration)
  • Step 3 Design atmosphere (ambient carbon

Earth Systems Engineering and Management
Principles Theory
  • Only intervene when required and to the extent
    required (humility in the face of complexity).
  • At the level of earth systems engineering and
    management (ESEM), projects and programs are not
    just technical and scientific in nature, but
    unavoidably have powerful cultural, ethical, and
    religious dimensions.
  • Unnecessary conflict surrounding ESEM projects
    and programs can be reduced by separating social
    engineering from technical engineering
    dimensions.
  • ESEM requires a focus on systems as systems,
    rather than as just constituent artifacts a
    dynamic, rather than static, mental model of
    underlying phenomenon.
  • Boundaries around ESEM projects and programs
    should reflect real world couplings and linkages
    through time, rather than disciplinary or
    ideological simplicity.
  • Major shifts in technologies and technological
    systems should be evaluated before, rather than
    after, implementation.

20
Earth Systems Engineering and Management
Principles Design and Engineering
  • Earth systems engineering and management (ESEM)
    initiatives should all be characterized by
    explicit and transparent objectives or desired
    performance criteria, with quantitative metrics
    which permit continuous evaluation of system
    evolution (and signal when problematic system
    states may be increasingly likely).
  • Design, engineering, and implementation of ESEM
    initiatives must not be based on implicit or
    explicit models of centralized control in the
    traditional rigid sense. Rather than attempting
    to completely define or dominate a system, the
    ESEM professional will have to see themselves as
    an integral component of the system, coupled with
    its evolution and subject to many of its
    dynamics. This will require a completely
    different psychology of engineering.
  • ESEM projects should be incremental and
    reversible to the extent possible.
  • ESEM should aim for resiliency, not just
    redundancy, in systems design. A resilient
    system resists degradation and, when it must,
    degrades gracefully even under unanticipated
    assaults a redundant system may have a backup
    mechanism for a particular subsystem, but still
    may be subject to unpredicted catastrophic
    failures.
  • ESEM should aim for inherently safe, rather
    than engineered safe, design. An inherently safe
    system fails in a noncatastrophic way an
    engineered safe system is designed to reduce the
    risk of a particular catastrophic failure mode,
    but there is still a finite probability that such
    a failure may occur.

21
Earth Systems Engineering and Management
Principles Governance
  • Earth systems engineering and management (ESEM)
    projects and programs by definition raise
    important scientific, technical, economic,
    political, ethical, theological and cultural
    issues. The only appropriate governance model
    under these conditions is one which is
    democratic, transparent, and accountable.
  • ESEM governance mechanisms should foster
    inclusive, multicultural dialog.
  • ESEM governance models, which deal with
    complex, unpredictable systems, must accept high
    levels of uncertainty as endogenous to the
    discourse, and view ESEM policy development and
    implementation as a dialog with the relevant
    systems, rather than a definitive endpoint. ESEM
    governance systems should accordingly place a
    premium on flexibility and the ability to evolve
    in response to changes in system state, and
    recognize the policymaker as part of an evolving
    ESEM system, rather than an agent outside the
    system guiding it.
  • The ESEM environment and the complexity of the
    systems at issue require explicit mechanisms for
    assuring continual learning, including ways in
    which assimulation of the learning by
    stakeholders can be facilitated.
  • There must be adequate resources available to
    support both the immediate ESEM project and the
    science and technology research and development
    necessary to ensure that the responses of the
    relevant systems are understood.
