The 'nexus' between water, energy and food (WEF) has gained increasing attention globally in research, business and policy spheres. We review the premise of recent initiatives framed around the nexus, examine the challenge of achieving the type of disciplinary boundary crossing promoted by the nexus agenda and consider how to operationalise what has to date been a largely paper exercise. The WEF nexus has been promoted through international meetings and calls for new research agendas. It is clear from the literature that many aims of nexus approaches pre-date the recent nexus agenda; these have encountered significant barriers to progress, including challenges to cross-disciplinary collaboration, complexity, political economy (often perceived to be under-represented in nexus research) and incompatibility of current institutional structures. Indeed, the ambitious aims of the nexus-the desire to capture multiple interdependencies across three major sectors, across disciplines and across scales-could become its downfall. However, greater recognition of interdependencies across state and non-state actors, more sophisticated modelling systems to assess and quantify WEF linkages and the sheer scale of WEF resource use globally, could create enough momentum to overcome historical barriers and establish nexus approaches as part of a wider repertoire of responses to global environmental change.

Private‐sector participation is widely perceived to be the solution to the failure of many publicly owned and managed water utilities to operate efficiently and make the investments required to meet community needs. However, there are no guarantees that privatisation will actually yield the desired performance improvements. Simply converting a public‐sector monopoly into a private one provides no competitive incentives for the utility to operate efficiently, make appropriate investments or respond to consumer demands. Likewise, privatisation per se need do little to improve sector performance if governments are unwilling or unable to tackle such underlying problems as overmanning, uneconomic water pricing policies, financing the provision of public and merit goods, and restricting over‐intrusive political intervention. Given the characteristics of the water and sanitation sector it is inevitable that some form of continued public regulation of the private companies will be necessary. The regulatory burden can be reduced by adopting a competitive form of privatisation, choosing a more competitive sector structure and devising an appropriate regulatory regime. However, it has to be recognised that there will be a trade‐off between making a venture attractive to private firms and introducing a notionally ‘ideal’ regulatory system. Regulation, in practice, is as much about creating the conditions under which private firms can operate effectively and efficiently as it is about protecting specific customer and public interests.

Objective — To explore the extent to which community pharmacists in the United Kingdom encounter and resolve ethical dilemmas in their daily work. Method — Semi‐structured interviews were carried out with a sample of community pharmacists representing a range of ages and pharmacy backgrounds. Two were from independent pharmacies and five from multiples. Key findings — Analysis of the transcripts of the interviews showed that ethical dilemmas were a feature of community pharmacy although most of the pharmacists were not conversant with the details of the Royal Pharmaceutical Society's Code of Ethics. The examples of ethical dilemmas quoted could be classified and interpreted to demonstrate a knowledge of the basic ethical concepts and the wider legal, occupational, organisational and personal value sets which encompass ethics in the work place. Ethical dilemmas arose as a result of the pharmacist's role as supplier of prescription medicines, guardian of over‐the‐counter medicines and intermediary between patient and carer/doctor. Other dilemmas were related to the legal framework surrounding medicines as well as the organisational, occupational and personal values of the pharmacist. Conclusion — The pharmacists in this study demonstrated awareness of ethical issues and their accounts indicate possession of practical skills to deal with moral uncertainty.
