Planning with complexity: an introduction for collaborative rationality for public policy

Corporate Social Responsibility: The Good, the Bad and the Ugly

High-throughput sequencing metabarcoding studies in marine biosecurity have largely focused on targeting environmental DNA (eDNA). DNA can persist extracellularly in the environment, making discrimination of living organisms difficult. In this study, bilge water samples (i.e., water accumulating on-board a vessel during transit) were collected from 15 small recreational and commercial vessels. eDNA and eRNA molecules were co-extracted and the V4 region of the 18S ribosomal RNA gene targeted for metabarcoding. In total, 62.7% of the Operational Taxonomic Units (OTUs) were identified at least once in the corresponding eDNA and eRNA reads, with 19.5% unique to eDNA and 17.7% to eRNA. There were substantial differences in diversity between molecular compartments; 57% of sequences from eDNA-only OTUs belonged to fungi, likely originating from legacy DNA. In contrast, there was a higher percentage of metazoan (50.2%) and ciliate (31.7%) sequences in the eRNA-only OTUs. Our data suggest that the presence of eRNA-only OTUs could be due to increased cellular activities of some rare taxa that were not identified in the eDNA datasets, unusually high numbers of rRNA transcripts in ciliates, and/or artefacts produced during the reverse transcriptase, PCR and sequencing steps. The proportions of eDNA/eRNA shared and unshared OTUs were highly heterogeneous within individual bilge water samples. Multiple factors including boat type and the activities performed on-board, such as washing of scientific equipment, may play a major role in contributing to this variability. For some marine biosecurity applications analysis, eDNA-only data may be sufficient, however there are an increasing number of instances where distinguishing the living portion of a community is essential. For these circumstances, we suggest only including OTUs that are present in both eDNA and eRNA data. OTUs found only in the eRNA data need to be interpreted with caution until further research provides conclusive evidence for their origin.

Wanted dead or alive? Using metabarcoding of environmental DNA and RNA to distinguish living assemblages for biosecurity applications

This article addresses the question of how to design participation processes in water management and other fields. Despite a lot of work on participation, and especially its evaluation, this question has received little attention in the research literature. However, it is important, because previous research has made it clear that participation may yield important benefits for humans and the environment but that these benefits do not occur automatically. One precondition is sound design. The design of participation processes has been addressed in detail in the so-called "craft" literature but more rarely in the scientific literature. This article helps close this gap by systematically analyzing and comparing five design guides to determine whether it is possible to combine them into a more robust guide. The article confirms that possibility and presents a preliminary outline for such a guide. Principles for participatory process orientation are presented, as well as numerous partially iterative steps. The adaptive process is laid out in a way intended to help designers determine the objectives of the participation process and the initial design context, and make preplanning choices that eventually lead to the selection of suitable participation mechanisms. There are also design tools that facilitate this work. We discuss how our findings are largely compatible with previous research on participation, notably the work on criteria for "good" or "effective" participation processes. We also argue that our article advances research on an important remaining question in the scientific literature on participation: What process should be chosen in which context? (Resume d'auteur)

Saving water for the future: Public awareness of water usage and water quality

Measuring social licence: What and who determines public acceptability of aquaculture in New Zealand?

Six of New Zealand’s 16 regional councils are trialling collaborative planning as a means of addressing complex challenges in freshwater management. Although some work has been undertaken to evaluate similarities and differences across those processes, the success or failure rests with the public’s acceptance of the processes and their outcomes. This is the first study to evaluate public perceptions of freshwater management in regions with collaborative processes. We surveyed 450 respondents in Hawke’s Bay, Northland, and Waikato, some of whom live in catchments in which collaborative processes are under way and some of whom do not. In addition to assessing awareness of the collaborative planning processes, the survey measured perceptions regarding the regional council’s management of freshwater resources, the extent of agreement regarding freshwater management among various interests, the fairness of freshwater management, and the extent to which respondents believe that their interests and concerns are included in freshwater management. We hypothesized that relative to respondents in parts of the region in which traditional processes are in places, respondents in catchments with collaborative management of freshwater resources would have more positive perceptions of management, agreement, fairness, and interests, even if there is low awareness that a collaborative planning process is under way. Survey results indicate that knowledge of collaborative processes is generally low and that living in catchments with collaborative processes does not impact respondents’ perceptions of management, agreement, fairness, or interests in Northland or Waikato. However, relative to Hawke’s Bay respondents living outside of the collaborative catchment, respondents living inside the collaborative catchment believe that the regional council’s freshwater management is better and fairer. Moreover, Hawke’s Bay residents living inside the collaborative catchment perceive less conflict over freshwater management than Hawke’s Bay respondents living outside the collaborative catchment. Further research is needed to identify the reasons for this regional variation.

Community perceptions of collaborative processes for managing freshwater resources

Collaborative approaches to freshwater planning are increasingly popular. In principle, collaborative processes allow wider access to all forms of knowledge, referencing the socio-ecological system and stakeholder values. Relevant science must be more broadly defined. Here we explore how the roles and skillsets of scientists and the nature of science knowledge differ in collaborative freshwater planning compared to traditional consultative processes, to assist those designing and participating in such processes. Our observations are drawn from interviews with scientists, policy planners, facilitators and an indigenous adviser from project teams managing collaborative processes in four regions of New Zealand. Results indicate that the role of the scientist in a collaborative process is less top-down informer, and more facilitator of learning. Thus ‘front-room’ scientists involved in collaborative planning processes require a broader skill set than those required for a traditional consultative proce...

Collaborative freshwater planning: changing roles for science and scientists
