title: Towards Robust Exchanges: Evaluating Ecological Compensation in New Zealand

authors: Brown, Marie Amanda

subjects: Resource Management Act

abstract: Ecological compensation is commonly employed but rarely evaluated around the world. In order to assess application of the tool in New Zealand, a systematic nationwide review was undertaken. The research used a combination of qualitative and quantitative tools (i.e. a mixed methods approach) to investigate outcomes associated with ecological compensation under the Resource Management Act 1991 and how variation among outcomes might be explained. Three key research components were addressed: compliance, practice and stakeholder perspectives.
Compliance
The levels of regulatory compliance were assessed in 81 consents and 245 conditions with an overall compliance level of 64.8%. Public organisations (75.5%) were more likely to comply than private companies (65.5%), followed by private individuals (54.7%). Administrative conditions (paper-based) were much more likely to be complied with (82.6%) than non-administrative (action based) conditions (49.6%). There were significant differences in compliance rates across different activities from Agriculture (4.8%) through to Energy Generation (100%), demonstrating the importance of understanding the nature of non-compliance in improving regulatory compliance and enforcement. 
Practice
The recognition of key implementation issues of ecological compensation were investigated based on the ecological exchanges approved in 110 consents. The key implementation issues were (1) equivalency, (2) spatial proximity, (3) additionality, (4) timing, (5) duration and compliance, and (6) currencies and ratios. Most exchanges approved under the RMA were ‘in-kind’ (i.e. broadly similar in type) but that their ecological equivalence was difficult to determine due to poor information. Most exchanges were close to the site of impact (65.5%), and those at a distance were typically the result of aggregated schemes such as mitigation trusts. Most requirements for ecological compensation can be considered to be additional, as there are few other means of compelling ecological restoration or other positive conservation activities in New Zealand. Most ecological compensation (94.5%) was required to be delivered concurrent with or after the activity that was approved with a range of mechanisms used to secure those outcomes. This research also showed that currencies and ratios are rarely used in the determination of ecological compensation.
Stakeholder perspectives
 Semi-structured interviews were conducted with 116 stakeholders from a wide range of disciplines, and demonstrated that while the potential of ecological compensation is well understood and its use is well-supported (96.5%), most stakeholders have significant concerns about implementation. Strong support (87.9%) exists for a more robust and formalized approach to ecological compensation.
For ecological compensation to contribute positively to the management of effects on the environment, the exchanges of biodiversity lost and gained must be robust. The present research has demonstrated that the implementation of ecological compensation in New Zealand is falling short of this expectation, and has identified a range of areas for improvement. The significant potential for failure inherent within ecological compensation requires mitigation with policy and practice improvements, and comprehensive follow-up and review of outcomes. Changes in the use of ecological compensation in New Zealand, toward a context that supports more robust exchanges and limits the potential for negative impact of the tool upon ecosystems and species are essential.

title: Long‐term residual properties and durability of glass fiber reinforced polymer composite exposed to alkaline solution and natural weather for a decade

authors: Ahmad Sawpan, Moyeenuddin

abstract: This paper presents a comprehensive analysis of the residual thermal and mechanical properties of pultruded glass fiber reinforced polymer composite bars following a decade of conditioning in an alkaline solution and exposure to natural weather conditions. The study focuses on evaluating the changes in the glass transition temperature (Tg) of the polymer matrix and its impact on the bar's mechanical performance. The results indicate that the Tg retained approximately 94.7% of its initial value, with the decrease attributed to the plasticizing effect of absorbed water. The flexural modulus, flexural strength, and transverse shear strength were found to retain 91.8%, 77.2%, and 97.3% of their original values, respectively. The reductions in strength and stiffness were primarily attributed to a weakening in the bonding between the fibers and the polymer matrix. Fractographic analysis revealed that the failure of the plasticized and softened polymer matrix contributed to the observed reductions in strength. Interestingly, the short beam shear strength remained relatively unchanged, as the diffusion of water into the core of the bars at ambient temperatures had a minimal effect. This slower water diffusion in the core led to insignificant degradation of the short beam shear strength.

Highlights
○ GFRP bars were exposed to alkaline solution and natural weather for a decade.
○ The water diffusion was a key factor in determining the residual properties of the GFRP bars.
○ The absorbed water plasticises the polymer matrix in GFRP bars.
○ The mechanical property losses in GFRP bars were associated with changes in the matrix property.

title: Developing culturally responsive psychology curriculum in Aotearoa New Zealand

authors: Wairoa-Harrison, Sophia

abstract: There are some significant wins in the development of a culturally competent undergraduate psychology curriculum in Aotearoa New Zealand. These include how Mātauranga Māori is incorporated into research methodology papers, neuroimaging papers, and degree offerings. However, the number of specifically Māori-focused papers has halved since 2007. Further research is needed to gauge students' experiences of the quality of cultural competency in these papers.
