Problem structuring methods or PSMs are widely applied across a range of variable but generally small-scale organizational contexts. However, it has been argued that they are seen and experienced less often in areas of wide ranging and highly complex human activity-specifically those relating to sustainability, environment, democracy and conflict (or SEDC). In an attempt to plan, track and influence human activity in SEDC contexts, the authors in this paper make the theoretical case for a PSM, derived from various existing approaches. They show how it could make a contribution in a specific practical context-within sustainable coastal development projects around the Mediterranean which have utilized systemic and prospective sustainability analysis or, as it is now known, Imagine. The latter is itself a PSM but one which is 'bounded' within the limits of the project to help deliver the required 'deliverables' set out in the project blueprint. The authors argue that sustainable development projects would benefit from a deconstruction of process by those engaged in the project and suggest one approach that could be taken-a breakout from a project-bounded PSM to an analysis that embraces the project itself. The paper begins with an introduction to the sustainable development context and literature and then goes on to illustrate the issues by grounding the debate within a set of projects facilitated by Blue Plan for Mediterranean coastal zones. The paper goes on to show how the analytical framework could be applied and what insights might be generated.

The past 15 years have witnessed the rise of post-development theory as a means of understanding the development discourse since the 1940s. Post-development argues that intentional development (as distinct from immanent development - what people are doing anyway) is a construct of Western hegemony. Sustainable development, they argue, is no different and indeed is perhaps worse, given that most of the global environmental degradation has been driven by consumerism and industrialization in the West. Critics of post-development counter by stating that it only provides destruction by tearing apart what is currently practiced in 'development' without providing an alternative. When post-developmentalists do offer an alternative it typically amouints to little more than a call for more grassroots involvement in development and disengagement from a Western agenda. Post-sustainable development analysis and counter-analysis has received remarkably little attention within the sustainable development literature, yet this paper argues that it can make a positive contributrion by calling for an analysis of discourse rather than a hiding of power differentials and an assumption that consensus must exist within a community. A case is made for a post-sustainable development that acknowledges that diversity will exist and consensus may not be achievable, but at the same time participation can help with learning. The role of the expert within sustainable development is also discussed. Copyright (C) 2008 John Wiley & Sons, Ltd and ERP Environment.

This paper critically reviews the application of a post-development analysis to sustainable development by employing a defined target for post-development analysis – the Environmental Kuznets Curve (EKC). Data from the 2005 Environmental Sustainability Index (ESI) for 146 countries are used to generate statistically significant EKC models, and the approach is deconstructed by employing post-development theory. While an ESI derived EKC is an easy target for post-development critique, there are foundations upon which both rest, and are not easily dismissed. Neither is the typical post-development 'alternative' of encouraging 'endogenous discourse' and grassroots movements at odds with sustainable development. As a result, this paper argues that sustainable development theory already incorporates much of the critique and alternatives raised by post-developmentalists. Indeed, what is more disconcerting is that sustainable development readily encompasses such apparently divergent ideas represented by the ESI, EKC and post-developmental critique and solutions.

Genetically modified (GM) crops and sustainable development remain the foci of much media attention, especially given current concerns about a global food crisis. However, whilst the latter is embraced with enthusiasm by almost all groups, GM crops generate very mixed views. Some countries have welcomed GM, but others, notably those in Europe, adopt a cautious stance. This article aims to review the contribution that GM crops can make to agricultural sustainability in the developing world. Following brief reviews of both issues and their linkages, notably the pros and cons of GM cotton as a contributory factor in sustainability, a number of case studies from resourcepoor cotton farmers in Makhathini Flats, South Africa, is presented for a six-year period. Data on expenditure, productivity and income indicate that Bacillus thuringiensis (Bt) cotton is advantageous because it reduces costs, for example, of pesticides, and increases income, and the indications are that those benefits continued over at least the six years covered by the studies. There are repercussions of the additional income in the households; debts are reduced and money is invested in children's education and in the farms. However, in the general GM debate, the results show that GM crops are not miracle products which alleviate poverty at a stroke, but nor is there evidence that they will cause the scale of environmental damage associated with indiscriminate pesticide use. Indeed, for some GM antagonists, perhaps even the majority, such debates are irrelevant – the transfer of genes between species is unnatural and unethical. For them, GM crops will never be acceptable despite the evidence and pressure to increase world food production.

Partnership is increasingly espoused as the best relationship between members of the sustainable development aid chain, and implies a respect for the position of all and a desire to avoid a situation where one group dominates another. It also implies a form of relationship that is not just 'better' for the sake of it but that is more able to help achieve sustainable development. However, given the inevitable inequalities in power between donors that have the resources and field partners that do not it can be hard to put this ideal into practice. This paper explores the function of partnership within a group of closely related institutions that comprise the Catholic Church development chain. The research focussed on three Catholic Church based donors (one from the USA and two from Europe) and their partners in Abuja Ecclesiastical Province, Nigeria. Relationships between and within various strata of the Church in Nigeria were also examined. Relationships were 'patchy' at all levels. One of the donors had a significant operational presence in Nigeria and this was regarded by some respondents as a parallel structure that seriously undermined local bodies. However, while problems existed, there was a sense of inter-dependence arising from a shared sense of values and Catholic Social Teaching, which allowed partners to work through their stresses and conflicts. It is the innate sustainability of the aid chain itself founded upon a set of shared values that provided the space and time for problems to be addressed.

Recent contributions by geographers on the relationships between states and citizens have documented the rise of rolled-out neoliberalism. Development agendas are, it is argued, increasingly dominated by the principles of market-driven reforms, social inequality, and a drive towards enhancing the economic competitiveness of the supply side of the economy. However, at the same time, a parallel set of discourses has emerged in the development literature which argues that it is principles of sustainable development that have, in practice, become dominant. The emphasis is, instead, on democratic empowerment, environmental conservation, and social justice. This paper examines the relationships between these ostensibly very different interpretations of contemporary development with an assessment of one of the Labour government's most ambitious planning agendas-the publication in February 2003 of the document Sustainable Communities: Building for the Future. The proposals are promoted as a "step change" in the planning system with a new emphasis on tackling shortages of housing in the South East and reviving the economy of the Thames Gateway area. The paper assesses the different ways in which such programmes can be interpreted and argues that contemporary development practices in countries such as Britain are constituted by a hybridity of approaches and rationalities and cannot be reduced to simple characterisations of rolled-out neoliberalism or sustainable development.

The concept of sustainable development forms the basis for a wide variety of international and national policy making. World population continues to expand at about 80 M people per year, while the demand for natural resources continues to escalate. Important policies, treaties and goals underpin the notion of sustainable development. In this paper, we discuss and evaluate a range of scientific literature pertaining to the use of transgenic crops in meeting sustainable development goals. It is concluded that a considerable body of evidence has accrued since the first commercial growing of transgenic crops, which suggests that they can contribute in all three traditional pillars of sustainability, i.e. economically, environmentally and socially. Management of herbicide-tolerant and insect-resistant transgenic crops to minimize the risk of weeds and pests developing resistance is discussed, together with the associated concern about the risk of loss of biodiversity. As the world population continues to rise, the evidence reviewed here suggests it would be unwise to ignore transgenic crops as one of the tools that can help meet aspirations for increasingly sustainable global development.

The Clean Development Mechanism (CDM) has successfully demonstrated that market-based mechanisms can achieve some cost effective emissions reductions in developing countries. However the distribution of CDM projects has been extremely uneven across countries and regions, and a few technologies and sectors have dominated the early stages of CDM experience. This has caused some to question whether the CDM has fallen short of its potential in contributing to sustainable development. We review the broad patterns of CDM project approvals and evaluate 10 CDM projects according to their sustainability benefits. The difficulty of defining “sustainable development” and the process of defining criteria by individual non-Annex 1 governments has meant that sustainable development concerns have been marginalized in some countries. Given these observed limitations, we present possible CDM policy futures, focusing on the main proposals for a post-2012 climate regime. Five options for enhancing the sustainable development benefits in the CDM are discussed, including proactive approaches to favour eligibility of emission reduction projects which ensure such co-benefits.
