| While there has been a large increase in investment in plantation forestry in New Zealand by smallholders during the past decade, there are still many smallholders who have chosen not to become involved in this land use or who are using only a portion of their potentially planted land for forestry. To understand why this is the case, this paper studies two issues, the differences between those who have and have not established plantation forests, and the factors that explain the proportion of land used in forestry by small landholders who have identified that they have potentially plantable land. Land used for forest plantations is treated as a two-step decision process, where first a landowner must decide whether they would consider planting trees at... |

| Researchers have estimated the total economic value of global ecosystem goods and services showing that a significant portion of humanity's economic well being is unaccounted for in conventional GNP accounting (Constanza et al., 1997). To demonstrate this point, authors have conventionally used highly aggregated landscape units for analysis (e.g., biomes), and average, not marginal values, of each ecosystem good or service are estimated for each unit using value transfer methodologies (Wilson et al., 2004). For example, Patterson and Cole (1999a, b) replicated the Constanza et al., (1997) approach by estimating economic values for Waikato and New Zealand ecosystem goods and services associated with standard land cover classes including horticulture,... |

| Water projects are typically evaluated using benefit cost analysis. Ecosystem services are the direct and indirect benefits that people obtain from ecosystems. Many of these benefits are ignored in benefit cost analysis, because of the absence of markets and the limited information or understanding of how the benefits from ecosystem services are produced. Regional or local government may be interested in learning how the value of ecosystem services associated with projects may change if a project occurs. Ecosystem Service Reviews aim to make ecosystem services explicit and quantifiable so that they can be accounted for in the evaluation of water use projects. Water storage projects can enable land use intensification to occur, and confer environmental... |

| Although an estimated US$6 billion is invested annually in our planet’s biological diversity, little research has been conducted on which conservation treatments work best or provide best value for money. Conserving biodiversity efficiently depends on identifying conservation treatments which provide greatest return on investment. Where controlled experiments are not possible, panel econometric techniques can be used to determine the effectiveness of conservation treatments. A long-running Yellow-Eyed Penguin (Megadyptes antipodes) nest count in New Zealand presents a golden opportunity to compare the effectiveness and cost effectiveness of three commonly used conservation treatments—trapping of introduced predators, revegetation, and intensive management.... |

| In New Zealand, it is increasingly recognised, including by government, that water resource allocation and water quality are issues of national importance. Agriculture is frequently portrayed by public media as a major user of water and a major contributor to worsening water quality. We outline the water management systems in New Zealand, and the use of water by agriculture. Official reports on agriculture’s impact on New Zealand water availability and quality are summarised. We report how the New Zealand public perceive water, its management, and the roles of agriculture in water issues. Data from a nationwide mail survey were analysed to determine how New Zealanders assess the state of New Zealand lakes, rivers and streams, and aquifers, the performance... |
