title: [Review of Geyserland - a guide to the volcanoes and geothermal areas of Rotorua by Bruce Houghton & Bradley Scott]

authors: Lowe, David J.

abstract: The publication in November 2002 of the second edition of the Society's 'Geyserland' guidebook is most welcome. The first edition was by far the best seller of the GSNZ guidebook series (although the special Japanese edition never really took off, figuratively or literally) and this updated version is sure also to be popular. The new guide is very attractive thanks to the wide use of colour photographs and figures, an informative yet readable (and occasionally witty) text, and a pleasing layout and design. The authors Bruce Houghton and Brad Scott are to be congratulated for their hard work and insight. So, too, is Simon Nathan who contributed many of the new, mostly top-quality photographs that make the book especially attractive (there are more than 30 colour photographs in the book, some spectacular). Simon also helped maintain the momentum that ensured the book was published after various delays. The editor and designer, Eileen McSaveney, is also commended for her work. As well as the interesting content and attractive design, the book appeals because it is printed on good quality paper (the ‘silky' covers even feel good) and it is perfect in size (BS) for use in the car and for packing in the suitcases of overseas visitors. Finally, it is very reasonably priced ($NZl7.95 incl. GST and postage and packing in New Zealand). For all these reasons, it therefore deserves to sell well.

title: Sustainability practices of SMEs: the case of NZ

authors: Lawrence, Stewart R.

subjects: SMEs

abstract: While individually small and medium sized enterprises (SMEs) may have small social, environmental and financial impacts, cumulatively their impact is significant. One of the fundamental questions is how a single economic entity, especially a small-scale enterprise, can be engaged in the uptake of sustainability practices. This question is particularly pertinent to New Zealand, where 98% of enterprises are SMEs. In this paper questions are raised about the conventional models of  business ethics  and accountability and their relevance to SMEs. The paper reports on actual practices and discusses the possibility of small enterprises having accountability for their social and environmental impacts. Ways of linking individual firm activities to sustainability, such as a communitarian model of accountability, are discussed and illustrated.

title: Monitoring te mana o te wai: Intergrating an indigenous cultural health index with conventional biomonitoring tools for improved freshwater management

authors: Edgecombe, Shana Jade Te Iaa Tarere

subjects: Freshwater

abstract: Globally, there are universal efforts to quantify and address human impacts on ecosystems. In particular, changes in land use and river regulation have led to drastic declines in stream and river ecosystem health. These human impacts are driving the global freshwater biodiversity crisis and degrade ecosystem services provided by aquatic habitats. In Aotearoa New Zealand there is widespread concern about the state of our Nation’s freshwater ecosystems. Coupled with a renaissance in Māori culture, there has been a drive to develop indicators that help articulate cultural values, assess ecosystem health from a cultural perspective, and provide greater agency for Māori in environmental monitoring and management. In my thesis, I sought to integrate an established cultural monitoring framework with conventional biomonitoring tools for improved freshwater management. I hypothesized that using a suite of monitoring approaches would help detect the impacts of human land use on stream ecosystem health, and that cultural indicators would be consistent with conventional measures in diagnosing land use impacts. I also hypothesized that there could be discrepancies between cultural monitoring and conventional approaches, as each represent different perspectives and ways of knowing streams and rivers. 
To test my hypotheses, I selected ten stream sites across the catchment of the Kuratau River, a major tributary of Lake Taupō. Based on River Environment Classification land cover types, I used a balanced study design with five sites draining indigenous forest, and five sites draining pastoral land. I measured key stream physicochemical properties and collected water samples for determination of nutrient concentration and faecal coliform counts. I also characterised instream and riparian habitat. I collected benthic macroinvertebrate samples and sampled water for environmental DNA (eDNA) to assess different facets of biodiversity. I measured decomposition using the Cotton Strip Assay and quantified periphyton biomass using a portable fluorometer. In combination with these approaches, I also used a Cultural Health Index, an established cultural monitoring framework that assesses three components: customary significance, taonga species/mahinga kai (food gathering), and the Cultural Stream Health Measure (CSHM) to assess identified attributes for stream health.
I found that pastoral land uses lead to a decline in stream ecosystem health when compared to sites draining indigenous forest. Pastoral sites had higher specific conductivity and concentrations of total nitrogen and nitrate. Habitat variables changed, with increased sedimentation and more degraded riparian zones in pastoral streams. Decomposition rates as measured by the cotton strip assay increased in the pasture sites, which was likely a response to increased nutrient availability. There were shifts in macroinvertebrate composition, with key indicator taxa for Indigenous forest sites including pollution-sensitive mayflies and stoneflies. Total taxa, EPT (Ephemeroptera, Plecoptera, Trichoptera), and aquatic insect richness all significantly declined in pastoral sites. Increases in primary production were less pronounced, but did increase alongside abundances of grazing caddisflies and snails in the sites draining pastoral catchments. 
The Cultural Health Index indicated that sites in the Kuratau River catchment had customary and mahinga kai values. CSHM responded negatively to pastoral land uses, and the effect size it described was congruent with other responses. The CSHM was strongly correlated with an indicator of riparian habitat condition (the Riparian Condition Index) and had weak negative correlations with sedimentation and stream temperatures. The CSHM was not correlated with macroinvertebrate indices, which may have been because of the relatively few sites sampled, the narrow impact gradient in the Kuratau catchment, and the lack of temporal replication. However, cultural monitoring approaches should be seen to complement conventional environmental monitoring methods for assessing freshwater and not be expected to duplicate them. The strength of the Cultural Health Index approach comes from establishing Māori agency to assess the environment through a Te Ao Māori lens, and to support and foster inclusion for tangata whenua epistemologies in environmental monitoring and resource management. Future research should consider greater hapū involvement and further explore the mechanisms driving changes in stream health and biodiversity.
