It requires not only biophysical knowledge developed by hydrologists and other environmental scientists, but an active partnership with catchment communities and stakeholders to break the 'paradigm lock' described by the UNESCO-HELP programme. This paper reports observations from ICM research in the Motueka HELP demonstration basin in the upper South Island of New Zealand. The Motueka occupies 2 170 km2 of land yet the river effects are felt on the seabed more than 50 km2 off- shore, so the true 'catchment' is larger. A hydrologically temperate mountainous catchment with horticultural, agricultural, plantation forestry and conservation land uses, the Motueka also hosts an internationally recognised brown trout fishery. Land and water management issues driving ICM research include water allocation ...

The policy objectives have included improving resource allocation, compensating the public for lost access and generating revenue for coastal management, although the relative emphasis on these objectives varied between agencies and over time. Implementation of a workable collection regime has repeatedly stalled in the face of strong interest group and agency opposition, compounded by inadequate policy planning, poorly designed consultation processes and imprecise legislation. In light of recent proposals to revive the central government collection of occupation rentals for coastal space this report investigates the causes of implementation failures in the charging regime.

Examination of the underlying meaning of efficiency and how it is defined, however, reveals that this tension between efficiency and equity is more apparent than real.

Rent is best treated separately from externalities even though a negative externality can be seen as a reduction in rent realised by another user of the resource. Depending on their design, rent recovery mechanisms can therefore capture the value of externalities otherwise unaccounted for.

Scenarios are assessed in terms of risk reduction per dollar spent. To keep the analysis manageable, we focus on vessel risks from hull fouling, as this is considered the primary pathway of vessel-related spread. Our analysis includes evaluation of the costs and benefits of different types of vector treatment as well as the possibility of continued vessel monitoring and control of pest populations in Bluff Harbour to reduce the risk of vector infection.
