Macro-socio-ecology-outline

1 ABSTRACT

Increasing human pressure on the planet from population, extractive and consumptive activity leads to resource scarcity and risks of crossing so-called planetary boundaries putting the human specis, other species and the entire earth system at risk. Further, with increasing demand of both continuing economic and social development along with a good and healthy environment and resources for the future - the need for a macroscopic view on how human resource use relates to the state of environment, as well as social and economic outcomes is needed.

The socio-ecological approach considers human activities as embedded and interacting with the biosphere. Socio-ecological systems have historically been considered when humans interact with the environment in extractive activities, often in marine or forest ecosystems.

At the core of the socio-ecological systems approach are questions about the dynamics of how governance systems affects the way humans interact with the environment and what they get out of their interaction with the environment.

Socio-ecological approaches, however, have a history of having been applied largely to local dynamics and to simple systems that can be analyzed analytically. As such, the socio-ecological approach has not delivered a guiding framework for how society can co-evolve in the long-term from the global to the national and regional scale.

In parrallel, global, regional or national frameworks for looking at socio-ecological dynamics have been developed. However, they have rarely been phrased explicitly as such.

Here we provide an overall framework for what can be considered a macro-socio-ecology. We tie together classic socio-ecological research with recent large scale approaches of similar character. We outline main research questions for macro-socio-ecology, its main methodological toolbox, and its policy and governance relevance.

National






2 THE NEED

  • Success of socio-ecology
  • A strong micro-level foundation
  • Recent foundational concepts
  • Planetary boundaries
  • Social foundation
  • Doughnut economics
  • A guiding national, regional and world map
  • not a GPS that will tell you how to get to where you want
  • To inspire discussions
    • About what we use our resources for
    • About the efficiency with which we use resources - environmental (extraction, transport), social, economic
  • Plenty of data - fragile framework
    • The national, regional and global level of organization

2.0.1 Environmental impact

\(I=PAT \Leftrightarrow I=PACT\)


2.0.2 Developmental outcome

\(D=PAE\)


2.0.3 Development outcome per environmental impact

\(\frac{D}{I} = \frac{PAE}{PAT} = \frac{E}{T}\)

\(\frac{D}{I} = \frac{PAE}{PACT} = \frac{E}{CT}\)


2.0.4 Where are the resources?

Implicit in \(C & T\)

2.0.5 Making resources explicit:

\(Resources, extracted: R_e, consumed: R_c, imported: R_i, exported: R_o\)

\(R_o + R_c = R_i + R_e\)


2.0.6 Environmental, social and economic impacts of resource use

Using the same subscripts for I, D and economic measures \(Ec\), for now denoting equity by \(Eq\).

Total environmental impacts of resource use.

\(\frac {I}{R} = \frac{I}{R_o + R_c + R_i + R_e} = \frac{I_o}{R_o} + \frac{I_c}{R_c} + \frac{I_i}{R_i} + \frac{I_e}{R_e}\)

Similar statements apply for \(Ec\) and \(D\).

\(\frac{Ec}{R} = \frac{Ec}{R_o + R_c + R_i + R_e} = \frac{Ec_o}{R_o} + \frac{Ec_c}{R_c} + \frac{Ec_i}{R_i} + \frac{Ec_e}{R_e}\)

\(\frac{D}{R} = \frac{D}{R_o + R_c + R_i + R_e} = \frac{D_o}{R_o} + \frac{D_c}{R_c} + \frac{D_i}{R_i} + \frac{D_e}{R_e}\)

One or more of the flows may be (set to) null depending on the question or type of process investigated.


2.0.7 Net outcomes versus outcomes associated with consumption of resources gains and losses ass


2.0.8 Resource consumption elasticities of D, I, Ec

\(\log(var) = a + b * \log(R_c)\)

\(elasticity = \epsilon = b\)

Research question

Rank variables with regard to \(b\). Assume other model than linear?

Variables with high cross-country resource elasticities should be scrutinized for more in-depth analysis. E.g. outliers within continents or development stages with partiularly high or low resource use per sustainability outcome.


2.0.9 Elasticity of consumed resources to consumption balance

\(\log(var) = a + b * \log \left( R_{ci} \right) + c * \log \left( R_{ce} \right)\)

Where \(R_{ci}\) and \(R_{ce}\) are the resources consumed through imports and domestic extraction, respectively.

Assuming equal proportional contributions to export from extracted and imported resources

\(\log(var) = a + b * \log \left( R_i * \left(\frac {R_i}{R_c+R_o} \right) \right) + c * \log \left( R_e * \left(\frac{R_e}{R_c+R_o} \right) \right)\)

Assuming exports first by domestic resources, then by imported resources of vice versa

Needs to be filled in.


2.0.10 Elasticity of consumption balance

\(\log(var) = a + b * \log \left(\frac{\left( R_{ce} - R_{ci} \right)}{\left( R_{ce} + R_{ci} \right)}\right)\)

Where \(R_{ci}\) and \(R_{ce}\) are the resources consumed through imports and domestic extraction, respectively.

Assuming equal proportional contributions to export from extracted and imported resources

\(\log(var) = a + b * \log \left( \frac{\left( R_{e} - R_{i} \right)}{\left( R_{e} + R_{i} \right)} * \frac{\left( R_{c} \right)}{\left( R_{c} + R_{o} \right)} \right)\)

Assuming exports first by domestic resources, then by imported resources of vice versa

Needs to be filled in.

      • Contestation and Inclusiveness, (1950-2000) These are the two principal components of 13-15 indicators of democracy, including those compiled by Freedom House; Polity; Arthur Banks; Alvarez, Cheibub, Limongi, and Przeworski, as updated by Cheibub and Gandhi; Bollen; and Cingranelli and Richards. The dataset covers most countries in the world from 1950 through 2000. In an article in the Journal of Politics (July 2008), Angel Alvarez, Claudia Maldonado, and I argue that these principal components, which capture 75 percent of variation in the most commonly used democracy indicators, measure Robert Dahl’s two dimensions of polyarchy: contestation and inclusiveness. We recommend that scholars use the standardized versions of these components (CONTESTstd and INCLUSstd), which have been adjusted to be comparable from year to year.”

5 LIMITATIONS OF THE MRIO APPROACH

From (Wiedmann et al. 2013)

  • “The two data sources used in this work are the global MRIO database Eora and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) Global Material Flow Database.”

  • “S2.3. Methodological Limitations. Recent advances in global MRIO modeling (2, 12) now provide the means to analyze and monitor the MF of nations more reliably than before. However, the method is not without limitations. MRIO accounts are provided initially in monetary terms rather than physical terms. So-called”price errors" can be introduced where individual transactions occur with a different price (dollars per quantity) than average. Allocation errors can occur due to low sectoral or product resolution. For example, a kilogram of gold included in a broad category of materials (e.g., “ores”) allocated to a broad production sector (e.g., “metals and mining”) will not be traced to its final demand as accurately as if gold were differentiated as a distinct input category and the MRIO used distinguished, more specific “gold,” “precious metals,” or “nonferrous metals” sectors rather than a broad metals and mining sector. In this study, we differentiated 35 types of materials and the MRIO used between 25 and 510 industrial sectors per country (5). For countries with more raw material-producing sectors, the allocation of DE data are therefore more accurate than for countries where fewer such sectors are available. For example, if there is just one “aggregate” extraction sector, a part of the “building stone” material flow might be allocated to the chemical industry because some limestone (which is also extracted by the aggregate"

  • “The limited resolution of some national input-output tables also constrains the method’s ability in addressing issues around critical metals and resource security due to the facts that (i) many of the critical metals are”specialty metals," which are use for very specific applications that cannot be easily represented by flows between aggregate sectors/products, and (ii) resource security roblems often arise from the presence of mono- or oligopoly structures within a sector. This is an area where hybrid approaches can be very useful. Here, input-output analysis (IOA) is combined with elements from process-based life cycle assessment (LCA) methods, such as those applied by Schoer et al. (13) in a study of the raw material consumption (RMC) of the European Union (EU). The hybrid method takes advantage of truncation-free enumeration of supply chains via IOA and productspecific detail via LCA (14-16). The current framework provides an important first step toward understanding potential risks associated with the global resource supply chain. More detailed information can be added targeting the hotspots identified through a hybrid approach, where process-specific information and aggregate product-level information are integrated. More general elaborations on the uncertainty of"



6 COMPARISON OF THE MRIO APPROACH TO TMC AND TMR

TMR - Total Material Requirement

TMC - Total Materical Consumption

From (Wiedmann et al. 2013)

  • “To calculate TMC and TMR, material intensity factors of imports and exports are derived from simplified life cycle inventories (4, 25). A drawback of this LCA factor method is that”that the ecological rucksack of a good which is passing more than one border in one or different process stages is counted more than one time within the volume" (4). This double-counting problem does not occur inMF calculations based on IOA because DE volumes are merely reallocated from production to consumption in a mutually exclusive and collectively comprehensive way. A further complication of the factor method used in TMC/TMR calculations is that coefficients of indirect material flows of imports and exports are mostly derived from specific production systems, such as Germany or the EU (25).“”
