Pesticides in the groundwater of a spring draining a sandy aquifer: temporal variability of concentrations and fluxes

A 250 ha agricultural catchment has been characterized with respect to its hydrogeology and groundwater contamination by pesticides from October 1999 to August 2004. Five years after the ending of atrazine (At) application, used since the sixties, At and deethylatrazine (DEA) are still systematically quantified at the outlet of the watershed with concentrations from 0.07 to 0.43 microg l(-1) for At, and between 0.14 and 1.16 microg l(-1) for DEA. Isoproturon and chlortoluron are detected in only one (0.3 microg l(-1)) and two (0.7 and 2.0 microg l(-1)) of the 124 semi-monthly samples, respectively. DEA concentrations can be very different between two samples with a 15-day time step. The annual mean exported fluxes of cumulated At and DEA are stable, which indicates a long time transfer in the unsaturated or saturated zone with a progressive leaching of the stock of At and DEA probably accumulated in the soil and the vadose zone. These fluxes, between 0.90% and 2.82% of the annual mean dose of At applied before 1999, similar to those calculated in several studies at the bottom of the root zone, could be explained by low adsorption and degradation properties of At and DEA in the unsaturated and saturated zone.     

Governing cities reflexively—The biocultural diversity concept as an alternative to ecosystem services

With the aim to embed ecology more forcefully into decision-making, the concept of Ecosystems Services (ES) has gained significant ground among policy-makers and researchers. The increasing recognition of the importance of urban green areas for the quality of life in growing cities has led proponents of ES approaches to argue for an uptake of the approach in urban environmental decision-making. However, the ES approach has been criticized for standing too much at a distance from local communities and their day-to-day practices and for insufficiently taking into account the potential trade-offs between different qualities or preferences. In this paper we argue that other concepts, doing other work, need to be added to the debate about futures of urban governance and research. Biocultural diversity is suggested as one such alternative concept. By its emphasis on diversity, biocultural diversity can account for the many ways in which people live with green areas in the urban landscape, acknowledges the different knowledges this involves, and can reveal conflicts and ambivalence that may be at stake. This sets up for a reflexive, transdisciplinary research process that questions and contextualizes knowledge and worldviews including those of researchers. A reflexive, transdisciplinary research, then, is a productive catalyst for forms of reflexive urban governance that recognise and respond to this diversity and provide platforms for contestation.     

Making sense of complexity in risk governance in post-disaster Fukushima fisheries: A scalar approach

This paper evaluates how geographical theories of scale can give a more robust understanding of the governance of complex environmental risks. We assess the case of fisheries in Iwaki City, Fukushima Prefecture in Japan following the 2011 nuclear disaster. Fisheries in Iwaki and Fukushima more widely are operating on a trial basis as understanding of the marine radiation situation becomes clearer, however questions remain over whether consumers will buy produce and to what extent full-scale fisheries will resume. Based on empirical fieldwork undertaken in Fukushima plus supporting documentary analysis, we construct a scalar account of post-disaster Iwaki fisheries. We use this to argue that framing post-disaster fisheries governance at the municipal scale rather than the prefectural scale has opened up opportunities for enacting the more two-way forms of risk governance that contemporary environmental issues may require. We also argue locally-situated ‘experts’ (e.g. fisheries extension officers and citizen science groups) play a key role in negotiating citizens’ and fishers’ relationships with larger-scale scientific discourses due to their ability to work across scales, despite having less techno-scientific expertise than their national-level counterparts. In turn, we suggest that in governance of complex environmental issues, policymakers ought to (a) consider how community-level expectations may differ from risk governance processes developed at larger scales; (b) identify key institutions or figures who can work across scales and support them accordingly; and (c) show cognisance to the social effects that may arise from spatial demarcation of environmental problems.     

Negotiating Indigenous knowledge at the science-policy interface: Insights from the Xáxli’p Community Forest

Despite increasing interest in learning from Indigenous communities, efforts to involve Indigenous knowledge in environmental policy-making are often fraught with contestations over knowledge, values, and interests. Using the co-production of knowledge and social order (Jasanoff, 2004), this case study seeks to understand how some Indigenous communities are engaging in science-policy negotiations by linking traditional ecological knowledge (TEK), western science, and other knowledge systems. The analysis follows twenty years of Indigenous forest management negotiations between the Xáxli’p community and the Ministry of Forests in British Columbia (B.C.), Canada, which resulted in the Xáxli’p Community Forest (XCF). The XCF is an eco-cultural restoration initiative that established an exclusive forest tenure for Xáxli’p over the majority of their aboriginal territory—a political shift that was co-produced with new articulations of Xáxli’p knowledge. This research seeks to understand knowledge co-production with Indigenous communities, and suggests that existing knowledge integration concepts are insufficient to address ongoing challenges with power asymmetries and Indigenous knowledge. Rather, this work proposes interpreting XCF knowledge production strategies through the framework of “Indigenous articulations,” where Indigenous peoples self-determine representations of their identities and interests in a contemporary socio-political context. This work has broader implications for considering how Indigenous knowledge is shaping science-policy negotiations, and vice versa.     

Conflicts and security in integrated water resources management

Water sector reforms based on the concept of Integrated Water Resources Management (IWRM) are criticized for not considering context, local realities or legitimacy during the implementation of water sector reforms. Universal remedies of IWRM can thus lead to resistance, conflicts and ultimately failures of interventions. This paper examines how conflicts and disharmony can be addressed by IWRM's instruments. It conceptualizes institutional security as a highly relevant issue to be addressed during water management interventions. Further, the paper advocates a reform of the holistic concept of IWRM to incorporate ‘peace and security’ as a new pillar of water management based on a broad understanding of societal goals that are embedded in the principles of good governance and sustainable development. It also reviews recent criticism of and debates in IWRM and explains the advantages of expanding the normative idea behind it.     

Boundary work in climate policy making in Brazil: Reflections from the frontlines of the science-policy interface

Despite challenges to the authority and legitimacy of science as a neutral representation of the world, expert advisors are playing an increasingly central role in environmental policy-making in both the Global North and South. This article explores the science-policy interface, based on the experience of the main author as a scientist and policy-maker at FEAM, a state-level environmental agency in Brazil. Contributing to the literature on boundary objects and organizations, the article details the practices necessary to manage the relationship between political and scientific norms in the development of the regional Climate and Energy Plan (CEP) for the state of Minas Gerais. To sustain the role of FEAM as a boundary organization mediating between political and scientific demands, a team of scientists and policy-makers had to perform different types of boundary work in a closely connected manner. It was necessary to actively frame climate change as an economic problem, and structure its solution in terms of mitigation mechanisms. Responding to changes in the national and international political context, FEAM reframed climate change from mitigation into largely an adaptation issue that could lead to win-win solutions as to attain saliency and avoid insurmountable political obstacles for its approval. Based on this experience, the article argues that the performance of boundary objects and organizations in the science-policy interface not only requires an ability to bring ‘truth to power’ but to also the capacity to sense, anticipate and avoid political obstacles. For this reason even though boundary organizations provide a breeding ground for institutional learning it is an unsuitable location for scientific or political revolutions.     

Complementary safeguards for robust regional watershed governance in a federation: New York City and its municipal water supply

In federations such as the United States, governments at various levels are experimenting with new watershed governance arrangements to protect water quality for both ecosystem health and human consumption. Such arrangements may bring previously uncooperative governments together to credibly commit to resource protection under the auspices of new and intricate formal institutions. Given the risks of cooperation, theory indicates that a robust arrangement will contain means of holding governing actors accountable to each other. This paper examines a purportedly successful case, the New York City watershed governance arrangement, to identify how safeguards against intergovernmental opportunism promote lasting cooperation. Using the qualitative method of process tracing, this paper finds that the New York City watershed governance arrangement uses structural, judicial, and popular safeguards against opportunistic behaviors by governing actors that might threaten the resource or the arrangement. The results indicate that such safeguards are present and interact with other safeguards and rule institutions at the state and federal level to maintain compliance.     

The governance of ecosystem services in river basins: An approach for structured data representation and analysis

River basins provide a wide range of ecosystem services important for human well-being. Ecosystem functions and their value to humans have been thoroughly studied. However, the role of governance characteristics for the sustainable management of ecosystem services has been largely ignored up to now. To close this gap, this article introduces the latest modifications to a database building on the Management and Transition Framework (MTF) that serve to study the relationship between water governance and management systems and their performance with regard to impacts on ecosystem services. This comprehensive approach facilitates structured data collection and representation in order to analyze single case studies or compare case studies regarding the governance and management of water resources and associated ecosystem services. It allows the user to investigate whether certain water governance characteristics, such as stakeholder involvement or vertical integration of governance levels, are associated with a change in the management of ecosystem services or a measurable change in their state. A simplified case from South Africa shows how the database modifications allow addressing links between governance and management processes on the one side and ecosystem services and the way they are handled on the other side. Applying the MTF database leads to evidence-based insights into best practices as well as failed management approaches and interventions. This in turn provides knowledge that can be transferred from science to practice supporting sustainable governance of ecosystem services.

Who should do what in environmental management? Twelve principles for allocating responsibilities

In environmental management there is often discussion on the allocation of responsibilities. Such discussions can continue for a long time and can form an obstacle for effective action. In this article twelve normative principles for the allocation of responsibilities are identified, coming from three different sources: the arguments used in discussions on responsibilities, Dutch and European law, and the environmental management literature. The principles are (1) capacity, (2) lowest social costs, (3) causation, (4) interest, (5) scale, (6) subsidiarity, (7) structural integration, (8) separation, (9) solidarity, (10) transparency, (11) stability (but not standstill), and (12) acquired rights. These principles point to fundamental tensions in environmental management and sometimes conflict with each other. At the same time they may help to resolve conflicts by providing common points of reference that are independent from the often conflicting interests of the discussants.
