Citizen science as a way of communicating science and doing public engagement has over the past decade become the focus of considerable hopes and expectations. It can be seen as a win-win situation, where scientists get help from the public and the participants get a public engagement experience that involves them in real and meaningful scientific research. In this paper we present the results of a series of qualitative interviews with scientists who participated in the 'OPAL' portfolio of citizen science projects that has been running in England since 2007: What were their experiences of participating in citizen science? We highlight two particular sets of issues that our participants have voiced, methodological/epistemological and ethical issues. While we share the general enthusiasm over citizen science, we hope that the research in this paper opens up more debate over the potential pitfalls of citizen science as seen by the scientists themselves.

A renewal of academic interest in agricultural restructuring in western Europe raises questions about causality, processes and outcomes. In particular, the relationship between deep-set structural tendencies and policy trends and the way these are constituted in relation to, and mediated through, the agency of individual land managers and other actors is emerging as a central research concern of rural social scientists. In this paper we focus on the first part of this equation, arguing that international and European agricultural restructuring needs to be rediscovered as an essentially sociopolitical project, the outcome of a struggle for influence and power between different class fractions of capital during a long and contested transition to a post-Fordist regime of accumulation. Rather than witnessing the shift towards a postproductivist agriculture anticipated by some recent commentators, we argue that the dominant framing is in favour of a neoliberal regime of market productivism, leading to the further integration of large parts of European agriculture into agro-food circuits of capital. While the neoliberal discourse which provides the intellectual justification for this process is heavily contested by advocates of a long standing form of neomercantilism and by a more recently invented discourse of agricultural multifunctionality, the entrenched position of neoliberal ideas and framings within the World Trade Organization (WTO) means that the ideology of the free market is coming to define the terms of international, and thus European, agricultural policy reform. The recent history of reform of the Common Agricultural Policy (CAP) and wider rural policy reform in the European Union (EU) nevertheless suggests that the European policy stance is one of partial resistance to unfettered liberalization, policy-makers apparently having embarked on an attempt to combine elements of the neoliberal programme with continued commitment to state assistance in various forms. This sets the frame for the regulation of an increasingly bimodal agricultural industry, in which spaces for postproductivism and rural development are being defined and defended in public interest and public good terms but where there are few opportunities to question the enforced segregation and commodification of rural space and environmental provision that this implies.

Since the implementation of Ghana's national Structural Adjustment Programme (SAP), policies associated with the programme have been criticized for perpetuating poverty within the country's subsistence economy. This article brings new evidence to bear on the contention that the SAP has both fuelled the uncontrolled growth of informal, poverty-driven artisanal gold mining and further marginalized its impoverished participants. Throughout the adjustment period, it has been a central goal of the government to promote the expansion of large-scale gold mining through foreign investment. Confronted with the challenge of resuscitating a deteriorating gold mining industry, the government introduced a number of tax breaks and policies in an effort to create an attractive investment climate for foreign multinational mining companies. The rapid rise in exploration and excavation activities that has since taken place has displaced thousands of previously-undisturbed subsistence artisanal gold miners. This, along with a laissez faire land concession allocation procedure, has exacerbated conflicts between mining parties. Despite legalizing small-scale mining in 1989, the Ghanaian government continues to implement procedurally complex and bureaucratically unwieldy regulations and policies for artisanal operators which have the effect of favouring the interests of established large-scale miners.
