Designing a knowledge co-production operating space for urban environmental governance—Lessons from Rotterdam,Netherlands and Berlin,Germany

Challenges for a sustainable urban development are increasingly important in cities because urbanization and related land take come up with negative challenges for the environment and for city residents. Searching for successful solutions to environmental problems requires combined efforts of different scientific disciplines and an active dialogue between stakeholders from policy and society. In this paper, we present a comparative assessment of the way policy-science dialogues have achieved knowledge co-production about strategic urban environmental governance action using the cities of Berlin in Germany and Rotterdam in the Netherlands as case studies. The ecosystem services framework is applied as a lens for policy–science interaction and a ‘knowledge co-production operating space’ is introduced. We show how policy officers, urban planners, practitioners and scientists learned from each other, and highlight the impact of this knowledge co-production for governance practice. We found that the concerted collaboration and co-creation between researchers and policy officers have led to mutual learning and establishment of relationships and trust in both cities. Not only the policy-relevance of research and its policy uptake were achieved but also new insights for research blind spots were created. In our conclusions we reflect on co-production processes with two types of conditions that we introduced to be most influential in the way knowledge can be co-created. These are conditions that relate to the way knowledge co-production processes are set-up and, conditions that relate to the expected value or benefit that the co-produced knowledge will bring across society, policy and practice.     

Knowledge brokerage designs and practices in four european climate services: A role model for biodiversity policies?

Environmental policies are broadly claimed to rely on sound scientific evidence because of the complexity, the uncertainty and the diverging political stakes that characterize issues like biodiversity decline or climate change. Classical advisory formats like assessments or standing advisory bodies have proliferated widely – especially at the global and national levels – yet exert only a limited influence on political decision-making, particularly in sub-national and local implementation contexts. Against this background, scholars have called for ‘bottom-up’ approaches to Science-policy interfaces that move from ‘problem to policy’. In the area of climate change, numerous ‘climate services’ have evolved at national, sub-national and even local levels, with the promise of being more decision-oriented. Four climate services in three European countries (the United Kingdom, Germany and Switzerland) are investigated regarding whether and how they institutionalize and enact knowledge brokerage in a credible, salient and legitimate way. Focusing on the institutional and strategic design principles of this advisory setting in climate policy, insights are generated for the biodiversity policy field, where comparable settings are still broadly lacking.     

Unexplored Diversity and Conservation Potential of Neotropical Hot Caves

The term hot cave is used to describe some subterranean chambers in the Neotropics that are characterized by constantly high ambient temperatures generated by the body heat of high densities of certain bat species. Many of these species have limited geographic ranges, and some occur only in the hot‐cave environment. In addition to the bats, the stable microclimate and abundant bat guano provides refuge and food for a high diversity of invertebrates. Hot caves have so far been described in the Caribbean and in a few isolated locations from Mexico to Brazil, although there is some evidence that similar caves may be present throughout the tropics. The existing literature suggests these poorly known ecosystems, with their unique combination of geomorphology and bat‐generated microclimate, are particularly sensitive to disturbance and face multiple threats from urbanization, agricultural development, mining, and tourism.

New science for global sustainability? The institutionalisation of knowledge co-production in Future Earth

In the context of complex and unprecedented issues of global change, calls for new modes of knowledge production that are better equipped to address urgent challenges of global sustainability are increasingly frequent. This paper presents a case study of the new major research programme “Future Earth”, which aims to bring ‘research for global sustainability’ to the mainstream of global change research. A core principle of Future Earth is the co-production of knowledge with extra-scientific actors. In studying how the principle of co-production becomes institutionalised in the emerging structure of Future Earth, this paper points to the existence of three distinct rationales (logics) on the purpose and practice of co-production. Co-production is understood as a way to enhance scientific accountability to society (‘logic of accountability’), to ensure the implementation of scientific knowledge in society (‘logic of impact’), and to include the knowledge, perspectives and experiences of extra-scientific actors in scientific knowledge production (‘logic of humility’). This heterogeneous conception of knowledge co-production provides helpful ambiguity allowing actors with different perspectives on science and its role in society to engage in Future Earth. However, in the process of designing an institutional structure for Future Earth tensions between the different logics of co-production become apparent. This research shows how logics of accountability and impact are prominent in shaping the development of Future Earth. The paper concludes by pointing to an essential tension between being inclusive and transformative when it comes to institutionalising new modes of knowledge production in large research programmes.     

Contexualising the tool development process through a knowledge brokering approach: The case of climate change adaptation and agriculture

This article applies a ‘knowledge brokering’ approach to contextualise the development of an integrated computer modelling tool into the real world policy context of adaptation of agriculture to climate change at the EU level. In particular, the article tests a number of knowledge brokering strategies described and theorised in the literature, but seldom empirically tested. The article finds that while the policy context can be used to identify a theoretically informed knowledge brokering strategy, in practice a strategy's ‘success’ is more informed by practical considerations, such as whether the tool development process is knowledge or demand driven. In addition, in practice the knowledge brokering process is found to be dynamic and messy, which is not always apparent in the literature. The article goes on to question the perception that there is always a need (or a desire) to bridge the gap between researchers and policy makers in the tool development process. Rather than a problem of design and communication, the science policy interface may be characterised more by a high level of competition between researchers and research organisations to have their tool legitimised by its use in the policy making process.     

Scientist and stakeholder perspectives of transdisciplinary research: Early attitudes,expectations, and tensions

Transdisciplinary approaches are becoming increasingly adopted as a way to research complex socio-environmental problems. Conceptually, transdisciplinarity aims to foster meaningful knowledge co-production through integrative and participatory processes that bring together diverse actors, disciplines, and knowledge bases. In practice, transdisciplinarity is more ambiguous. While there is a growing body of literature on such approaches, there remains no widely-accepted definition, concrete framework, or empirical strategy for how to carry out a transdisciplinary project. We propose that this lack of explicit structure and entrenched meaning leaves space for transdisciplinary approaches to be shaped by the evolving network of participating scientists and stakeholders, according to their perspectives of the approach and what it embodies. Here, we examine the perspectives of a diverse group of actors (n = 42) embarking on a 10-year transdisciplinary research project focused on building resilience to natural hazards and disasters in New Zealand. We present the findings of qualitative surveys and group interviews that investigate stakeholders’ and scientists’ early perspectives of transdisciplinary, or co-created, research. The study represents the first stage of longitudinal research that will continue over the course of the project. Results show that early actors in the project share an overall consistent understanding of co-created research. Participants described a process that integrated diverse people and knowledge; created benefits on both a social and personal level; fostered clear, two-way dialogue; and overcame pragmatic and intrinsic challenges. Collectively, participants agreed with adopting transdisciplinary approaches to natural hazard, risk, and resilience research, with stakeholders showing a stronger degree of agreement than scientists. While attitudes towards transdisciplinarity were overall positive, a number of underlying conflicts emerged in regards to carrying out new modes of knowledge production within traditional social and institutional structures. These conflicts result in a tension that is felt by actors involved in transdisciplinary projects early on, and in some cases, influences perception of their ability to fully participate in such an approach. Evaluating actor perspectives and expectations early in the transdisciplinary process can give insight into how attitudes, expectations, and conflicts might shape transdisciplinary efforts, and can provide relevant parameters for assessing change over time.     

Evolution of co-management: Role of knowledge generation,bridging organizations and social learning

Over a period of some 20 years, different aspects of co-management (the sharing of power and responsibility between the government and local resource users) have come to the forefront. The paper focuses on a selection of these: knowledge generation, bridging organizations, social learning, and the emergence of adaptive co-management. Co-management can be considered a knowledge partnership. Different levels of organization, from local to international, have comparative advantages in the generation and mobilization of knowledge acquired at different scales. Bridging organizations provide a forum for the interaction of these different kinds of knowledge, and the coordination of other tasks that enable co-operation: accessing resources, bringing together different actors, building trust, resolving conflict, and networking. Social learning is one of these tasks, essential both for the co-operation of partners and an outcome of the co-operation of partners. It occurs most efficiently through joint problem solving and reflection within learning networks. Through successive rounds of learning and problem solving, learning networks can incorporate new knowledge to deal with problems at increasingly larger scales, with the result that maturing co-management arrangements become adaptive co-management in time.     

Understanding socio-cultural dimensions of environmental decision-making: A knowledge governance approach

Sociological critiques of scientific research processes and their application have developed nuanced understandings of the social, cultural and political forces shaping relationships between science and decision-making. Simultaneously, environmental researchers have sought to construct more engaged, dynamic modes of conducting research to facilitate the application of science in decision-making and action. To date, however, there are relatively few theoretically-oriented approaches that have been able to draw productive connections between the sociological critique and the practical applications that can aid in navigating this complex and diverse milieu. In this article, we propose that the concept of “knowledge governance” can bring together targeted inquiry into the socio-political context in which environmental science is situated, alongside analysis of specific interventions that change knowledge-to-action relationships. Drawing together Jasanoff’s (2005) concept of civic epistemology with Cash et al.’s (2003) knowledge systems for sustainability approach, this knowledge governance inquiry framework offers an integrative lens through which to critically reflect on knowledge-based processes, and incorporate that deeper understanding into intervention efforts. We briefly illustrate its application with reference to a pilot project examining conservation decision-making in the Western Pacific island nation of Palau.     

Exploring Indigenous Understandings of River Dynamics and River Flows: A Case from New Zealand

Indigenous communities are particularly sensitive to the use and development of freshwaters, as they hold distinct perspectives on water which reflect their identity, and their custodial obligations to manage tribal waters. Within New Zealand, Maori (the indigenous people) have, for generations, voiced their concerns about the continual modification of waterways within their tribal territories. Until about the mid-nineteenth century, water quality was at the forefront of issues concerning human manipulation of rivers and streams. A range of new issues then arose that were increasingly concerned with reduced river flows. Of the many techniques developed to address these issues, many rely heavily on professional expertise and objective, scientific philosophies, which often fail to recognize cultural values, and benefit from cultural knowledge. This essay presents examples of the knowledge of streams and rivers held within Maori communities that could benefit contemporary resource management if it can be determined how cultural knowledge and practices and scientific approaches can be communicated and integrated.
