Reformism, as the current dominant sustainable world approach, is then subjected to critique.

Section 5 continues the EFA review by 2. A Sustainable World considering what outcome, in EFA terms, What it means for there to be a sustainable humanity should be striving for. This is an world is a pluralistic and contested concept, important question to address as without grounded in differing value systems, clarity of this point, this paper's critique of perceptions of reality, and cultural contexts Reformism from an EFA perspective would (Gibbs & Krueger 2005; Osorio, Lobato & lack a meaningful measure against which to Castillo 2005). This plurality poses model the consequences of pursuing the challenges for summarising exactly what a Reformist agenda. In considering this EFA- 'sustainable world' means and, as Dobson outcomes question, a number of issues that (1996) points out, it makes the task of materially impact on how the EFA data are constructing a meaningful sustainable world interpreted, but that are currency poorly definition virtually impossible. As an developed in the literature, are reviewed in alternate to a definitional approach, Dobson some detail. Following this review, some (1996) recommends a typology general parameters are established on which representation of complex concepts such as the EFA modelling is then based. that of a sustainable world, and this advice of Dobson's was followed for the Project.

The key points to note are: But what Ecological Footprint vs Biocapacity measure (a) Humanity's collective Ecological should humanity be striving for? In the EFA literature, a minimum condition for humans to live sustainably Footprint of 2.6 ghpc is running at 144% in a global context is talked of in terms of humanity of available Biocapacity of 1.8 ghpc, needing "[its] global Footprint [to] be less than or meaning that a position of ecological equal to the global biocapacity (Footprint Network exists. 2006, para 15A) and "at a global level the minimum requirement for sustainability is that humanity's (b) This overshoot position means that footprint be smaller than the 's biological available Biocapacity is insufficient to capacity" (Nijkamp, Rossi & Vindigni 2004, p. 753). meet current human demands. Instead, The claim of "equal to" in the first quote is the KNR base is being depleted and troublesome as to live sustainably, humanity's global- level Ecological Footprint needs to be less than wastes (in this case, CO2) are available Biocapacity.

Gaining clarity on this issue, to which mostly by: (i) the economically and this section turns its attention, is of high importance as reliance on the raw published EFA data can paint an politically weak who suffer a otherwise distorted picture of humanity's current disproportionately low level of access to unsustainable ways of life.

The claim by EFA (Andersson & Lindroth 2001; Westra promoters is that the question of meeting the 2006). needs of non-human species sits outside of the research question EFA seeks to answer.

So although taking the that the low-end 10%-12% estimate is point made by EFA advocates concerning the inadequate to protect the Earth's biodiversity exclusion of non-human species Biocapacity (Soulé & Sanjayan 1998; CABS 2003; needs from the Biocapacity measure, the Stokstad 2005), with a 10% value seen by question of 'how much Biocapacity should be some as likely to put up to half of the Earth's set aside for non-human species?' still needs species at risk of human caused extinction to be answered. Without some guidance on (Soulé & Sanjayan 1998). Values in the this matter, setting a target for sustainable order of 40%-60% of the Earth's surface, human use of Biocapacity becomes whether quoted in reference to protected impossible. areas or, more generally, as needing protection from intrusive human actions in a This 'how much for other species' question is broader landscape sense, are often cited as poorly addressed in the literature. Most necessary to offer an adequate basis for estimates talk of how much of the Earth's biodiversity protection (Soulé & Sanjayan surface should be set aside as protected 1998; Wilson 2002; Mackey 2004; Stokstad areas, with low estimates in the 10%-12% 2005). The claimed biodiversity protection range through to higher estimates of 40%- outcomes of these 40%-60% values are 60%+ (Soulé & Sanjayan 1998; Wackernagel consistent with both the Reformist and et al. 1999; Wilson 2002; CABS 2003; Transformational biodiversity protection Stokstad 2005). But there is a difference narratives, although the Transformational between claiming how much of the Earth's view tends to the higher end (or beyond) of surface should be set aside as protected this value range (Clifton 2010)). areas, and how much of the Earth's Biocapacity should be left for other species. Further, the Biocapacity that needs to be set An example of this difference is evident in aside for non-human species is not just any the World Commission on Environment and space, but needs to focus on biological Development's report '' criteria (UN 1992; Foreman 1995), as (the Brundtland Report) (WCED 1987). opposed to continuing past strategies of Some authors claim that this Report calls for protecting areas of the Earth's surface that about 12% of the Earth's surface to be set are of little or no value to humans, or areas aside in protected areas (e.g. see suited only to human recreational actives Wackernagel & Yount (1998)). This 12% (Callicott 2003; Ehrlich & Ehrlich 2008). number does not however appear in the This is important when considering the Brundtland Report but is rather an Biocapacity measure used in EFA extrapolation of the Report's proposal that, calculations, as Biocapacity is based on based on the state of affairs at the time the biologically productive areas of land and Report was written, "the total expanse of water that support significant photosynthetic protected areas needs to be at least tripled if activity and accumulation that can it is to constitute a representative sample of be used by humans.

Conservative values resilience are identified in the literature, EFA data tends to underestimate the namely engineering resilience and ecological Ecological Footprint value and overestimate (or socio-ecological) resilience (Peterson, available Biocapacity. The reasons for this Allen & Holling 1998; Walker & Salt 2006) are grounded in a preference for the (socio-ecological resilience is the term used conservative use of data where uncertainty in this paper for this second form of exists, and exclusion from the calculations of resilience).

But to get lost in at a global level, not living sustainably in the a 'should it be 20% or 50% or something sense of living within the limits of available else' discussion can in some ways distract Biocapacity. In this section, the Reformist from the bigger picture. As shown in Figure and Transformational sustainable world 2, the setting aside of 20% of Biocapacity approaches are presented in I=PAT terms. In sees the current Ecological Footprint value addition, I=PAT is used to project the current running at about 180% of the resulting Ecological Footprint forward based on the Biocapacity available for human use. At a Reformist view, with a purpose of 50% of Biocapacity value, the Ecological considering the implications of pursuing the Footprint is some 289% of human available Reformist narrative in bringing humanity's Biocapacity. Either way, the numbers are Ecological Footprint within Biocapacity significant and the challenges humanity faces limits.

The focus for Reformism however is more towards market pricing mechanisms than the strong scale-limiting approaches incorporated in the Transformational approach.

But for the absolute decoupling in the global context. sake of the analysis in this paper, two figures are used: (a) a collective decoupling of 'P+A' from changes in 'I' of 25%, that is, a 1% This lack of absolute decoupling between change in 'P+A' equals a 0.75% change in 'I' population and economic growth, and of (consistent with the EU findings), and (b) a continued ecological damage, is well 50% decoupling where a 1% change in 'P+A' documented (for examples, see OECD equals a 0.50% change in 'I' (an optimistic (2008), UN (2005), and Jackson (2009)).

7.1.2. Efficiency of use of resources in the 7.2.1. Green production and consumption process Green consumerism refers to the Efficiency gains at the production level are development, packaging, and marketing of well recognised as a means by which firms products in a way that is claimed to be improve productivity, reduce costs, and 'environmentally friendly'. The marketing increase wealth (Princen 2005; Gould, message is that people can save the world Pellow & Schnaiberg 2008). But production through consumption choices, and can efficiency does not necessarily equate to consume with a clear conscience. For overall resource use reduction. Termed the business the message is improved profits. '', pursuing production based The complete package is a claimed win for can, and does, result in business, for the consumer, and for the increased production and consumption that environment (Beder 2002; Bell 2009). negates some or all of the resource efficiency gains that were otherwise expected. This Critics argue however that green effect is also apparent at the consumption consumerism fails to address the underlying end where through say, initiatives within problem of resource consumption and households to reduce energy costs through instead, promotes further consumption under power saving activities, the money saved is the misguided view that society can simply spent on alternate consumption somehow consume its way out of its (Princen 2005; Gould, Pellow & Schnaiberg unsustainable state (Beder 2002). In addition, 2008; Polimeni et al. 2009). In this respect, green consumerism is seen to continue the relative decoupling of economic growth from business-as-usual marketing strategies of KNR consumption, in the absence of some need creation through the deliberate alternate mechanism for containing increased engineering of feelings of dissatisfaction and production and consumption, can decrease deprivation in people's lives, offering the the likelihood that absolute decoupling can solution to this dissatisfaction through be achieved. In I=PAT terms, this means that consuming a particular product (in this case, the production and consumption efficiency a 'green' product). This marketing strategy component of 'T' has the effect of increasing drives continued consumption and economic 'A' such that 'T' simply cannot keep up with growth with flow-through implications of 'A' based pressures (York & Rosa 2003; increasing KNR use (Raiklin & Uyar 1996; Jackson 2009). Hamilton & Denniss 2005).

7.2. Less harmful behaviours in the 7.2.2. Restructuring of the economy production and consumption process Restructuring-of-the-economy relates to the Less harmful production and consumption claimed shift in production and consumption behaviours incorporate many factors activities within economies as they continue including the use of less polluting to industrialise. The claim is that the further substances, manufacturing products that can down the industrialisation path a nation be easily recycled, extracting KNR in less moves, the greater the proportion of its harmful ways (such as the harvesting of fish economy that is dedicated to less resource with less by-catch impact), and so on. But intensive service and information industries. the question remains as to whether these In this respect, increased economic growth actions have unintended consequences of results in a transformation to a less increasing consumption and hence negating environmentally damaging economy, some of the apparent gains achieved as consistent with the EKC proposition occurs in the efficiency context discussed discussed in section 6.3. above. To explore this question, two aspects of the less-harmful-behaviours issue will be Counter arguments to this claim include: (a) considered namely: (a) green consumerism, the apparent switch to service industries is and (b) restructuring of the economy. not as great as it seems, as much of the recorded change results from businesses 17

The Ecological Footprint and business domains – by way of the calculation is consumption, not production, application of Ecological Footprint Analysis based, where what matters in the calculation (EFA) in conjunction with I=PAT. This is a person's Ecological Footprint, or critique suggests that Reformism is collectively a nation's overall Ecological challenging to believe as credible. The Footprint, based on what is consumed reliance on technology solutions (i.e., 'T' in regardless of where in the world those goods I=PAT) requires these solutions to achieve or services are produced (Kitzes 2007; two things: (a) a 100% decoupling of Footprint Network 2008b). Figure 6 shows population and economic growth pressures the Ecological Footprint measure for national from the Ecological Footprint, and (b) a groupings based on income. What is evident reduction in humanity's existing aggregate from these data is that high income countries Ecological Footprint from its current (i.e., countries of the industrialised West, unsustainable level. The extent of 'T' based plus Japan and some other highly reductions needed to achieve these outcomes industrialised nations) run by far the highest is both substantial and well beyond what is Ecological Footprint and one that is well evident as occurring in practice. The above the global average. In this sense, the enormity of the Reformist challenge is restructuring-of-the-economy argument is further evidenced by noting that the average unconvincing.

It is beyond the scope of this paper fast enough to counter the ecological impacts to explore the Transformational approach in of the continued economic growth they help detail, however the key points to note are create. these. First, the Transformational approach seeks to act directly on all of the I=PAT The core message presented in this paper of elements as opposed to the Reformist the highly questionable ability of the approach that is mostly 'T' focused (see Reformist approach to deliver a sustainable Figure 3). In this respect, the world outcome is not new, but rather adds to Transformational approach offers a greater the weight of existing evidence. Arguments range of solutions than the Reformist rejecting the possibility of continued approach is willing to tolerate. Next, the economic growth, demonstrating the Transformational approach specifically seeks ineffectiveness of efficiency solutions to a socio-ecological resilience approach to how achieve needed reductions in human impacts humanity goes about conducting itself, as on the Earth's ecosystems, and affirming the compared to the Reformist approach that is increasing rather than decreasing impact focused on maximisation and optimisation humanity is having on the Earth's strategies within both social and ecological ecosystems, are well rehearsed. These systems (Clifton 2010). In both of these arguments appear in the literature in a respects – direct action on all I=PAT number of areas including the sustainability elements, and a socio-ecological resilience literature in general (e.g., Meadows, Randers focus – the Transformational view seems to & Meadows (2004), Princen (2005), Shiva present a pathway forward that is more likely (2005), Victor (2008), and Jackson (2009)), to see a sustainable world achieved than the and within various academic disciplines Reformist approach can otherwise offer. including ecological economics (e.g., Daly, H & Farley (2004), and Common & Stagl Earlier in this paper it was noted that (2005)), the emerging field of green Reformism is the current dominant approach economics (e.g., Cato (2009)), and to a sustainable world. Reformism however, (e.g., Gould, Pellow not only dominates, but it does so to the & Schnaiberg (2008), and Bell MM (2009)). exclusion of the Transformational narrative in political and business circles.

If, as this paper, and as ecological resilience requirements in other authors propose, Reformism is Biocapacity allowances, and (c) adding to the challenging to believe as a credible pathway weight of evidence in considering the merits to a sustainable world, then why does of the Reformist view as a credible pathway Reformism dominate to the exclusion of the forward for humanity.

One answer is that the third of the reasons for Reformism's In the process of reviewing the I=PAT and set out in section 2 – the EFA concepts and their application to sustainability agenda has been captured by critiquing the Reformist approach, a number the politically and economically powerful of challenges emerged where further research elite – is in fact true. If this is the case, then may be beneficial. The key areas evident in even if further research on the various issues the above discussion are: (a) the conservative detailed in this paper, plus other efforts to nature of the EFA data, (b) the amount of interrogate the Reformist and Biocapacity that is available for human use, Transformational approaches, result in an (c) the drivers of change in Biocapacity and increasing weight of evidence against how this might unfold in the future, and (d) Reformism, the challenges of embracing an the drivers of future Ecological Footprint alternate narrative take on a whole new values and in particular, the relationships dimension.
