Under the New Zealand Emission Trading System (NZETS), post-1989forestry land (the exotic or indigenous forest land that was not used forplantation on 31 December 1989) in New Zealand is eligible for reward foreach tonne of CO2-eqv sequestrated by reverting from pasture to indigenousscrub. We use the Land Use in Rural New Zealand (LURNZ) model to conduct2 simulations assuming that one tonne of CO2-eqv costs $25; The referencecase is that no one has entered the NZETS, the other scenario is thatthe whole agriculture sector and indigenous forest (but not plantation) haveentered the ETS.

Adaptation in agro-ecological systems will be important for moderating the impacts of climate change. Vulnerability assessments provide the basis for developing strategies to reduce social vulnerability and plan for climate adaptation. Primary industries have been identified as the most vulnerable industry sector globally. We review how primary producers might be socially vulnerable to climate change and develop a ‘vulnerability typology’ of cattle producers based on survey responses from 240 producers across northern Australia.

Monitoring changes in the terrestrial carbon cycle and vegetation health can only be undertaken over large areas and on a regular basis using ecological indicators derived from satellite-based sensors. Climate conditions in Mediterranean ecosystems have undergone, and are projected to undergo, significant change in the future with marked impacts on forest and shrubland vegetation. In the southwest of Australia (SWAU), endemic tree species have experienced significant declines in health and mortality since the early 1990s primarily due to these climatic changes.

In New Zealand and Australia, rural landowners believe that local predator control to protect indigenous biota exacerbates European rabbit Oryctolagus cuniculus problems on their land. We assess the validity of their concerns by reviewing the published literature on effects of predators on rabbit abundance. In New Zealand, where rabbits and their predators are introduced, predators appear to have relatively little effect on rabbit numbers compared with other factors leading to mortality, such as disease, flooding of burrows and burrow collapse.

It is suggested that valuing objects is a distinctive human trait. It is a prerequisite for rational behaviour. Factors that are likely to influence valuations, the difficulties of getting agreements about valuations and the limited perspective of economics as a basis for valuation are discussed generally. Attributes of Otago Peninsula that seem to be valuable and worth conserving are listed and discuss taking into account possible conflicts in getting maximum value from these attributes.

The environmental consequences of agriculture are of growing concern. One example of these consequences is the effect of agricultural pollutants on the Great Barrier Reef (GBR), a world heritage-listed ecosystem lying off the tropical north-eastern coast of Australia. Pollutants from agricultural lands (fine sediments and attached nitrogen (N) mainly from grazing lands, and dissolved N and pesticides mainly from cropping) in catchments draining into the GBR lagoon threaten the health and resilience of this ecosystem.

Little is known about the effects of mud crabs population patterns on their exploitation. We used complementary approaches (experimental, fisher-based) to investigate how small-scale variations in density, size and sex-ratio related to the ecology of S. serrata may impact fishing practices in New Caledonia. Crabs were measured/sexed across 9 stations in contrasted mangrove systems between 2007 and 2009. Stations were described and classified in different kinds of mangrove forests (coastal, riverine, and estuarine); vegetation cover was qualitatively described at station scale.

This paper examines the Waikato River Agreement in Principle by considering the implications of accommodating cultural values in natural resource management for the Waikato River and New Zealand. Economics will continue to play an integral part in the management of the Waikato River and natural resources in New Zealand. The settlement provides an opportunity to rethink how to incorporate Maori knowledge, cultural and social relationships, and social, cultural, and economic wellbeing in an integrated, holistic, and coordinated approach.

Many production landscapes are complex human-environment systems operating at various spatio-temporal scales and provide a variety of ecosystem goods and services (EGS) vital to human well-being. EGS change over space and time as a result of changing patterns of land use or changes in the composition and structure of different vegetation types. Spatio-temporal assessment of EGS can provide valuable information on the consequences of changing land use and land cover for EGS and helps to deal with this complexity.
