| Intensification of agricultural practices is occurring in Canterbury. Dairy farm conversions continue with land use increasing 132% since 1995. Current concerns emanate predominantly from issues of water quantity and quality, in particular the degradation of lowland streams. These and other costs are not transmitted through markets for dairy products, these negative externalities represent allocation and equity concerns for regional policy makers. This study canvassed regional policy administrators, assembled available valuation studies and performed rudimentary calculations based on reviewed New Zealand literature to form an estimate of the external costs of dairy farming in Canterbury. External costs are estimated at $28.7 to $45 million annually. Using... |

| 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... |

| 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... |
