Synthetic gene drive approaches are nascent technologies with potential applicability for pest control for conservation purposes. Responsible science mandates that society be engaged in a dialogue over new technology, particularly where there exist global ramifications as with gene drive. We hypothesize that public attitudes towards gene drive are not formed on scientific knowledge or demographics alone, but are heavily influenced by underlying worldviews, which encapsulate a broad and interactive system of attitudes, beliefs, and values. To test this, we conducted a national survey in New Zealand (n = 8199) and found that respondents clustered into four distinct segments with underlying worldviews, better able to explain attitudes toward gene drive than either the participants' scientific knowledge or other explanatory factors such demographics, political ideology or religiosity. We found that the use of gene drive for biodiversity conservation currently has moderate (32%) levels of support in New Zealand but that varied substantially across the four segments. Should gene drive become a technically viable approach for pest control, understanding the worldviews that shape public decision-making can guide a more empathetic engagement process and empower society to participate in informed decisionmaking about if and how gene drive should be used for conservation purposes. ARTICLE HISTORY

Invasive animal species threaten global biodiversity. In New Zealand invasive species threaten iconic native species, and scientists are seeking approval to research new technologies that might be capable of eradicating these invasive species. The aim of this research was to understand what New Zealanders with an interest in pest control consider to be the main risks and benefits of introducing new technologies to manage invasive species. We invited key informants to participate in the focus groups, selecting people with knowledge and experience of pest control issues in New Zealand. Data were collected from seven focus groups held in three locations across New Zealand. A thematic analysis of the data was then conducted in which three key themes emerged: concern about the risk of unintended consequences, the benefits of landscape-scale technologies, and New Zealand being an early adopter of new technologies. The focus groups articulated a variety of benefits from introducing new technologies – such as replacing dangerous poisons with non-toxic alternatives – but it was the risks of the new technologies that dominated the discussions. Given these results, we recommend an education and communication strategy focussed on social learning, in conjunction with a codesigned decision-making process, to help establish social licence for the application of potentially controversial technologies.

This paper explores the concept of soil health from a human well-being perspective in Aotearoa New Zealand. Globally, soils play an integral role in wider society and the environment by maintaining a large range of ecosystem services and benefits. As populations and resource constraints increase and food production and food security become growing issues globally, there is a recognition of the importance of defining soil condition or soil health for sustaining all ecosystems, including services and benefits to humans, plants, animals, and micro-organisms. While the ecosystem services approach has helped to illuminate the varied services soils provide, an understanding of the complex human–soil relationships and values has been missing. Those seeking to understand and form concepts about soil health have concentrated on the more inherent biochemical, physical and economic (e.g., productivity) aspects of soils, but not on the human, social or cultural dimensions. It is argued in this paper that soils form an integral part of our social and cultural fabric and are fundamentally important to human and societal well-being. The way humans interact with, value and use soil is a critical part of determining the health and sustainability of soil ecosystems. We discuss how a well-being approach can improve understanding of soil health with respect to societal goals and needs. We believe this type of approach, which includes social and cultural dimensions, provides a more diverse and inclusive knowledge base and perspective to better inform the development of integrative policy. This would lead to improved management and decision-making of land resources and soils in Aotearoa New Zealand and globally.

SummaryNo published information is available on the foraging ecology and choice of feeding habitat of New Zealand’s rarest breeding bird: the New Zealand Fairy Tern (NZFT) Sternula nereis davisae. To address this gap, we conducted an assessment of the largest remaining breeding population at Mangawhai Harbour, Northland, New Zealand, during the chick-rearing period of the 2010/2011 breeding season. We combined visual tracking of birds with prey surveys and stable isotope analyses, and we present the first quantitative assessment of NZFT foraging. We recorded 405 foraging dives that show NZFT foraging habitat includes the water edges, shallow channels, and pools on the tidal flats of mangrove-lined (Avicennia marina var. resinifera) parts of the estuary; tidal pools on mud- and sandflats in the mid-estuary and lower harbour; the shallow margins of the dredged main channel in the lower harbour; the oxbow lagoons on the sand spit; and coastal shallows. Our study identifies the mangrove-lined highly tidal and shallow mid-estuary and the lagoon on the sand spit as foraging hotspots for the Mangawhai breeding population of the NZFT. The prey survey employed a seine-net sampling method at identified NZFT foraging sites and yielded 4,367 prey-sized fish of 11 species, two of which had not previously been reported in Mangawhai Harbour, as well as numerous shrimps. The most abundant fish were gobies of the genus Favonigobius. Our stable isotope results highlight gobies as the most important prey for NZFT chick rearing, also indicating that flounder Rhombosolea sp. contribute to NZFT diet. We raise the possibility that shrimps may also constitute a substantial diet component for NZFT, potentially providing up to 21% of diet mass for adult birds. While our results provide a first basis to understanding the feeding ecology of NZFT during their breeding season in order to facilitate conservation planning, further research is required to address inter-annual variation and to identify key foraging grounds for this Critically Endangered bird at other breeding sites.

Initiatives such as education, incentives, and regulations are used to change people’s behaviour and thereby achieve policy objectives. Understanding and predicting the willingness of people to change their behaviour in response to an initiative is critical in assessing its likely effectiveness. We present a framework proposed by Kaine et al. (2010) for understanding and predicting the motivation of people to change their behaviour in response to a policy initiative. The framework draws on the marketing concept of ‘involvement’, a measure of motivation. Through application to a predator control case study, we show how the framework may be used to predict people’s responses to a policy initiative and how these predictions might help agencies develop strategies to promote behaviour change.
