The Agricultural Production Survey (APS) is Statistics New Zealand’s vehicle for collecting important information about New Zealand’s primary production. It is an annual postal survey and covers land use, livestock and arable farming, horticultural and forestry production, and selected farm…

The New Zealand Emissions Trading Scheme (NZ ETS) was introduced through the Climate Change Response Act in September 2008 and remains in force. The forestry sector has been directly affected by the NZ ETS since 1 January 2008 and stationary energy, liquid fuels and industrial emissions have…

NPV and LEV are established and common approaches to valuing single rotation and infinite rotation forests respectively, when the rotation age is fixed in advanced. More recently, Real Options approaches have been employed to value single and infinite rotation forests with a flexible harvest age…

Conservation biological control (CBC) aims to improve conditions for natural enemies in agricultural landscapes and has the goal of reducing pest species below threshold level to thus avoid the need for synthetic chemicals. The CBC approach has been introduced in several counties, including New…

This paper updates an analysis of returns from major productive land uses in New Zealand carried out in 2008. Trends in profitability over time are shown, and a preliminary investigation of the relationship between land-use change towards forestry (new land planting) and forestry profitability…

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…

1. The distribution and abundance of invasive species can be driven by both environmental variables and land management decisions. However, understanding these relationships can be complicated by interactions between management actions and environmental variability, and differences in scale…

This paper describes key linkages between land management activities and stream water quality for a 5230ha catchment used for intensive pastoral agriculture in southern New Zealand. Due to low annual rainfall and the wide coverage of soils with low available water-holding capacities, flood…

The emerging biofuel sector has drawn great interest as an alternative source of fuel for transportation. The expansion of biofuels greatly impacts world agricultural markets, since currently, the primary feedstocks for ethanol and biodiesel production are field crops and their derived products…

We conducted two field experiments to explore the reactions of feral ferrets (Mustela furo) to traps and bait dispensers set on pastoral farmland in central North Island, New Zealand. First, in 2004 we showed that only six of 13 radio-collared ferrets resident near four observation stations…

Data from the 1990-1994 period presented in the "Brazil's Initial National Communication" document indicated that the country is one of the top world greenhouse gas (GHG) emitters. A large majority of Brazil's GHG emissions come from deforestation mainly of the Amazon biome…
