Resource use options for the Upper Manuherikia Valley : 603 case study

Abstract

Current resource development in New Zealand is unprecedented in its pace and scale. Development activities have implications for other resource uses and for future generations. Conflicts generated must be recognized and a comprehensive framework for resource planning developed for their reconciliation at all levels.

The goal of this study is to understand resource use options in the Upper Manuherikia Valley of Central Otago. This area contains two of nine lignite deposits in the South Island which are being considered for processing into transport fuels (Figure 2). Development of the lignite will affect present and potential resource uses in the valley. The study area is defined on the west by the St Bathans Range, on the north by the boundary of the Manuherikia catchment, on the east by the Hawkdun Range and Idaburn Hills, and on the south by the road linking St Bathans and Hills Creek (Fig. 1).

Part A identifies present and potential resource users in the study area. Agriculture and recreation are present uses. Forestry, lignite mining and processing, down-valley irrigation and reserves are examined as potential uses. The characteristics and physical requirements of these options are determined and discussed.

Part B comprises four scenarios which represent a broad range of resource use alternatives. Implications for the physical and social environment are outlined in each scenario, as are the implications for local, regional and national policy.

In Part C, recommendations are made for a comprehensive planning framework which may be used to reconcile the conflicts identified in each scenario.
