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.

Feral goats in the 34 169 ha Egmont National Park (North Island, New Zealand) have been subject to sustained ground-based hunting with dogs since 1925. We analysed trends in hunting success from 1961 to 1999. During 1961–86 the catch per unit effort (CPUE) declined from 7 kills hunter–1 day–1 to <1 kill hunter–1 day–1. Since 1987 the CPUE has been maintained at low levels. The key impediment to switching from a strategy of sustained control to eradication is whether or not all goats can be put at risk. We suggest that managers test this experimentally in part of the park before embarking on an eradication programme. On the basis of an empirical estimate of rm and an assumption of logistic growth, we estimated the current population to be ~1047 animals. Removing 50% or 90% of the population annually would eradicate the population in >50 years or 12 years, respectively. Annual immigration of goats would prevent eradication under all scenarios.

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.

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.

As part of the 2030 Agenda for Sustainable Development, sustainable development goal 2 (SDG2) specifically seeks to ‘End hunger, achieve food security and improved nutrition and promote sustainable agriculture’. However, there is no clear prescription for how this goal should be achieved which allows various donors adopting diverse strategies to all claim they are contributing to SDG2. This article examines whether policies of five donors on food security and agriculture in the Pacific Islands region are likely to help to achieve SDG2. Fundamentally, the current and future wellbeing of many Pacific Island peoples, many of whom live on small, geographically dispersed islands with limited market access, is strongly tied to their abilities to produce food for themselves. This is somewhat overlooked by bilateral donors from Australia and New Zealand who invest relatively small amounts in the agriculture sector of Pacific countries and show little interest in supporting people's food security through local sourcing and production for subsistence. From an SDG2 perspective of ending hunger for all people, it is positive to see that, by contrast, two multilaterals have shown commitment to a more balanced and holistic approach to food production in the Pacific Islands region.
