Sustainable development, shock and awe? London 2012 and Civil Society

There is a disconnection between the top-down, elite, nature of sports mega-events and the ostensible redistributive and participatory sustainable development agendas staked out by BINGOs (Business-based International Non-Governmental Organizations) such as the contemporary International Olympic Committee (IOC). Focusing specifically on the London 2012 Summer Olympic and Paralympic Games, we argue that, for all the environmental technology advances offered by sports mega-events, their dominant model remains one of a hollowed-out form of sustainable development. Despite significant technical and methodological innovations in environmental stewardship, the development model of the London Olympics remains predicated on the satisfaction of transnational investment flows. We discuss what this means for claims about the staging of a ‘green’ Olympic Games.

Transdisciplinarity and reflective practice in sustainable development learning

Using various extracts from the reflective commentaries of MSc students, this article explores how transdisciplinarity and reflective practice operate in the programme. It shows how learners managed the uncertainties of sustainable development through regular critical and evaluative reflections. Students were able to apprehend the several worlds making up the sustainable development project and their own personal learning journey through the various competing, complementary and occasionally contradictory perspectives, modes of learning, sources of knowledge and information. One conceptual device facilitating this process was offering an understanding of sustainable development as constituting a ‘dialogue of values’, an approach that effectively invites students to square the metaphorical circle - i.e. broadly reconciling (ecological) sustainability with (economic) development.

Sustainable development

The United Nations has pithily defined sustainable development as progress that ‘meets the needs of the present without compromising the ability of future generations to meet their own needs’. But sustainable development remains highly contested and is subject to a wide variety of interpretations, applications, and criticisms. Moreover, those seeking fully to understand this critical concept are confronted with a (sometimes dispiritingly) voluminous body of scholarly, polemical, and journalistic writing. Edited by the acclaimed author of Understanding Sustainable Development (Earthscan, 2008), this new title from Routledge’s Critical Concepts in the Environment series answers the need for an authoritative reference work to make sense of the vast literature on sustainable development, and the continuing explosion in research output. Drawing on a wide variety of sources that take full cognizance of the rich background and necessary adaptability of the concept to the imperatives of time, place, and culture, and which emphasize its connected and transdisciplinary nature, the editor has brought together in four volumes the canonical and the best cutting-edge work to produce an indispensable ‘mini library’. The collection covers the history, mediation, application, and likely future orientations of sustainable development, both conceptually and as a continually emerging practice. Sustainable Development is fully indexed and includes comprehensive introductions, newly written by the editor, which place the collected materials in their historical and intellectual context. It is an essential reference collection and is certain to be valued by scholars and students—as well as serious policy-makers and practitioners—as a vital one-stop research and pedagogic resource.

Searching for resilience in sustainable development:learning journeys in conservation

Resilience is a term that is gaining currency in conservation and sustainable development, though its meaning and value in this context is yet to be defined. Searching for Resilience in Sustainable Development examines ways in which resilience may be created within the web of ecological, socio-economic and cultural systems that make up the world in. The authors embark upon a learning journey exploring both robust and fragile systems and asking questions of groups and individuals actively involved in building or maintaining resilience.

Heterogeneous catalysis for sustainable biodiesel production via esterification and transesterification

Concern over the economics of accessing fossil fuel reserves, and widespread acceptance of the anthropogenic origin of rising CO2 emissions and associated climate change from combusting such carbon sources, is driving academic and commercial research into new routes to sustainable fuels to meet the demands of a rapidly rising global population. Here we discuss catalytic esterification and transesterification solutions to the clean synthesis of biodiesel, the most readily implemented and low cost, alternative source of transportation fuels to meet future societal demands.

Effects of engine cooling water temperature on performance and emission characteristics of a CI engine operated with biofuel blend

The temperature of the coolant is known to have significant influence on engine performance and emissions. Whereas existing literature describes the effects of coolant temperature in engines using fossil derived fuels, very few studies have investigated these effects when biofuel is used. In this study, Jatropha oil was blended separately with ethanol and butanol. It was found that the 80% jatropha oil + 20% butanol blend was the most suitable alternative, as its properties were closest to that of fossil diesel. The coolant temperature was varied between 50°C and 95°C. The combustion process enhanced for both diesel and biofuel blend, when the coolant temperature was increased. The carbon dioxide emissions for both diesel and biofuel blend were observed to increase with temperature. The carbon monoxide, oxygen and lambda values were observed to decrease with temperature. When the engine was operated using diesel, nitrogen oxides emissions correlated in an opposite manner to smoke opacity; however, nitrogen oxides emissions and smoke opacity correlated in an identical manner for biofuel blend. Brake specific fuel consumption was observed to decrease as the temperature was increased and was higher on average when the biofuel was used. The study concludes that both biofuel blend and fossil diesel produced identical correlations between coolant temperature and engine performance. The trends of nitrogen oxides and smoke emissions with cooling temperatures were not identical to fossil diesel when biofuel blend was used in the engine.
