While the definition of sustainability remains open for all to contribute to and participate in, there do seem to be some notions it has come to embody that should not be neglected as the definition coalesces. Among these are the ethical and social dimensions of sustainability. Whether or not it is appropriate, required, or even desirable, concepts like social equity, human rights, ethical sharing of commons, etc. have increasingly come under the umbrella of the sustainability discourse. Even if “sustainability” as a bare word doesn’t imply those things, the concept of sustainable development certainly has taken on those dimensions. That sustainability might be redefined or re-scoped to be a purely environmental or a rigidly scientific endeavor, is not an immediate concern of this paper, though if that were to occur (whether for the sake of simplicity or pragmatics), it should be done explicitly so the ethical sub-discourse can be maintained (indeed, sustained) by some other movement.

This paper proposes a mechanism by which such a migration in terms can be prevented. First, in reviewing the work of Denis Goulet, it shows the solid basis for including an ethical aspect in the sustainability discourse. Second, it points out that Karl-Henrik Robèrt’s highly-lauded and broadly-employed sustainability framework, The Natural Step, is deficient in this area. This deficiency provides the impetus for, finally, proposing a mechanism by which The Natural Step can be extended to include the important social and ethical dimensions of sustainability. This mechanism is based on the capabilities approaches that, in many respects, evolved out of Goulet’s early work. Augmented accordingly, TNS can continue to be used without fear of overlooking the social and ethical aspects of the sustainability discourse.

Businesses, as with other sectors in society, are not yet taking sufficient action towards achieving sustainability. The United Nations recently agreed upon a set of Sustainable Development Goals (SDGs), which if properly harnessed, provide a framework (so far lacking) for businesses to meaningfully drive transformations to sustainability. This paper proposes to operationalize the SDGs for businesses through a progressive framework for action with three discrete levels: communication, tactical, and strategic. Within the tactical and strategic levels, several innovative approaches are discussed and illustrated. The challenges of design and measurement as well as opportunities for accountability and the social side of Sustainability, together call for transdisciplinary, collective action. This paper demonstrates feasible pathways and approaches for businesses to take corporate social responsibility to the next level and utilize the SDG framework informed by sustainability science to support transformations towards the achievement of sustainability.

This research on the early metal ages of the Wadi el-Hasa focuses on settlement systems and attempts to explain how social, economic and political adjustments helped tribal groups survive under natural (i.e., climatic) and anthropogenic (i.e., land degradation, erosion) stress factors. The shifting of subsistence base from agropastoral to pastoral is reflected in site and population densities, diversity of site types, levels of internal complexity, and levels of social organization via the presence of large settlements, like villages, which acted as economic and administrative centers emerge as risk reduction mechanisms.

The cycles of abandonment and resettlement are evaluated within the concept of social reorganization and such changes are assessed as parts of economic revitalization attempts. The social changes that emerge from such shifts are evaluated from the perspective of the scale-free networks modeled and tested through statistical methods, such as ANOVA, for spatial and temporal patterns, while patterns of land use and the impacts of changing climate and anthropogenic activities are evaluated with GIS.

Following the dimorphic society and heterarchic social organization concepts, the discussion emphasizes that tribal groups adjust population density, range and intensity of activities in marginal landscapes, like the Hasa, in order to prevent environmental degradation. These patterns may change once these marginal landscapes are integrated to more complex social organizations. Although this takes place in the Hasa during the Iron Age, the research results imply that environmental degradation did not take place possibly due to the continuation of extensive subsistence patterns, along with the emergence of the long-distance caravan trade as a major economic incentive.
