title: The need to reconfigure consistency and variability to best manage changing flood risks in Aotearoa-New Zealand

authors: Serrao-Neumann, Silvia

abstract: Flooding is Aotearoa-New Zealand’s most frequent natural hazard, and there is high confidence that climate change is making extreme rainfall events more frequent and intense. Additionally, there are significant development pressures which could both increase the number of people and assets at risk and the flood hazard. To date, there is no publicly available consistent approach to accurately determine flood risk on a national scale, nor for how this may be changing; although there is a growing legislative requirement to provide quality information over multiple spatial scales. This paper draws on empirical data to gain insights on how to best manage changing flood risks in Aotearoa-New Zealand from the perspective of centrally organised entities. Findings confirm the need for a nationally consistent approach to flood risk management, better understanding of Aotearoa’s communities and their vulnerability to floods, equitable access to quality information and decision-support tools, and better understanding of the economic impacts on differing communities, regions and places. The paper concludes that to achieve a flood-resilient Aotearoa, flood governance needs to be reconfigured to achieve national consistency in flood risk management whilst enabling targeted variability at the local scale.

title: A Multi-level Technology Acceptance, Adoption and Implementation Model for Achieving Government-Citizen Dialogue: An Omani Case Study

authors: Al Namani, Hamed

subjects: E-government

abstract: The number of commercial applications that exploit Web 2.0 social media is increasing rapidly. However, little is known about the challenges that public sector organizations face when they decide to adopt Web or other technology-based applications, and offer them to consumers; particularly when governmental and civil service organizations are involved. This is particularly true in developing non-Western regions, such as the Middle East, where 'Arab Spring' developments in 2011 stimulated interest in the ability of social networking to mobilize citizens against ruling elites. Consequently, this study investigated Oman's public sector to gain a deeper understanding of the adoption and use of information technology innovation and its potential to engage governments more closely with citizens. In essence, it aimed to develop a comprehensive model of ‘organizational adoption’ and ‘citizen use’ of technology for achieving meaningful online dialogue. The focus of this study is not social media applications per se, but rather it concerns any Web or other technology-based application that is suited to improving dialogue between government organizations and citizens. 

The final model was derived over three distinct phases of research using a mixed method approach. In Phase I, an initial literature review developed understanding of global trends in e-Government adoption and clarified the study aims, scope, and primary research question. A more extensive literature review was then undertaken to derive a tentative 'first-cut model' theoretical framework. This contains factors considered critical to both achieving successful organizational adoption of IT innovations and a meaningful dialogue between governments and citizens. These are presented from three distinct perspectives or levels; the National level, Organization level, and Management level. In Phase II of the research, case studies involving three Omani civil services organizations helped to refine the tentative model. Policymakers and citizens were interviewed to confirm issues and identify additional adoption and use factors. Finally, in Phase III a participatory action research approach was used to test completeness of the refined model, which culminated in the final model.

This study has shown that meaningful online dialogue can be used for different purposes: for facilitating access to decision-makers (mainly), for responding to citizens' enquiries and for addressing rumours. At the National level, government support—meaning political, economic and technical aspects—plus social changes has driven the acceptance of technology for improving government-citizen interactions and for sharing of information. In contrast, the major National level inhibitors are: limited availability of broadband services, other digital divide barriers, national culture barriers and political barriers. At the Organization level, having an IT strategy and top management support, adequate human, financial and technical resources, and a strong citizen-centric orientation are all factors that drive the adoption. Conversely, lack of capability, inappropriate internal culture, and resistance to change can all inhibit adoption. At the Management level, good preparation, proficiency with technical issues, accessibility and marketing issues, appropriate consideration of operational issues and end user needs are critical for implementation of Web or other technology-based applications needed to create meaningful online dialogue. Conversely, major implementation challenges concern inadequate IT infrastructure, resistance to change, and inability to recruit a suitable management team. The research also found that creating a management team, recruiting qualified moderators, controlling the discussion, responding to citizens, and defining the interaction characteristics (objectives, target citizens, participation policies and rules, etc.) are all critical for achieving a meaningful dialogue. 

The developed model has added to the knowledge of how to encourage technology innovations in governmental organizations, in particular through online dialogue that motivates citizens and other stakeholders to engage in meaningful discussions. For non-Omani governmental organizations having similar operational characteristics, the developed model offers lessons for policymakers and others who wish to enhance citizens' interactions; or who wish to improve the reputation of the organization; or bring about citizen-acceptable policies and decisions. Future work should be aimed at testing the developed social networking adoption model in other industries, sectors and national settings.

title: Boat electrofishing survey of fish abundance in the Ohau Channel, Rotorua, in 2017

authors: Hicks, Brendan J.

abstract: The aim of the survey was to provide on-going monitoring of the fish communities and abundance by boat electrofishing in the Ohau Channel, especially fish species that are taonga to Maori (tuna, or eels, morihana, or goldfish, and kōura, or freshwater crayfish). In the current study, we present the findings from the eleventh year of sampling (2017) and a summary of previous surveys.
We used the University of Waikato’s 4.5 m-long, aluminium-hulled electrofishing boat to catch a total of 1,110 fish and 3 kōura (18.2 kg in total) from 11 sites on 5 December 2017. The sites comprised 2,909 lineal m and 11,636 m2 in area. Kōura (freshwater crayfish) and 6 fish species were present, with common bully the most abundant species (up to 29.6 fish 100 m⁻² at the site 8, edge habitat). Goldfish (up to 14.2 100 m⁻²) was the next most abundant species, with most goldfish at sites 8 and 11 in and around the side channel. Common smelt were next the most abundant species (up to 11.4 fish 100 m⁻²). Mean density of bullies (7.8 fish 100 m⁻²) was much higher than for smelt (1.69 fish 100 m⁻²). Kōura had a patchy distribution with only 3 individuals were caught at two sites.
Comparing catches over the 11 years of sampling, the mean abundance of common bullies in 2017 was consistent with densities in most post-wall years (after 2007), but lower than in 2007 before wall closure (Newman-Keuls multiple range test, P = 0.034). The cause of fluctuating bully abundance is not known, and was not accounted for by changes in water clarity expressed as black disc distance (BDD), water temperature, or water conductivity. Poor water clarity can reduce the efficiency of electrofishing, but low BDD did not correspond with low common bully densities. In 2017, smelt abundance had recovered somewhat from the low catches from 2014 to 2016.
Goldfish biomass increased initially (2009-2010) because of targeted fishing in the side channel (site 11), which has dense macrophytes and offers good habitat for goldfish with no flow. However, the continued rise in goldfish density from 2012 on suggests a real increase in goldfish numbers. In contrast to most previous years, no eels were caught in 2017.
Analysis of fish densities before and after wall closure is hampered by the single data point before closure. However, we now have 10 years of post-wall data, and comparisons of means and standard deviations suggest that the number of bullies have been lower since 2008 with the exception of 2015, when bully densities were the same as 2007, i.e., before wall closure. The large number of small juvenile bullies (<30 mm) suggests that recruitment is taking place in the channel, so fluctuating bully abundance is likely to be controlled by factors other than wall closure.
