    Climate change is shaped and understood through assumptions of causality and temporality that enable and constrain feasible approaches to environmental governance, approaches that may reproduce inequalities. Reducing Emissions from Deforestation and Forest Degradation (REDD+) provides an entry point to examine the intersecting assumptions and politics around climate change and how it is managed. Actors in the REDD+ regime promote particular assumptions about the causality and temporality of climate change, which are often privileged over local ways of being and knowing.

    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 approached to within 8m of two stations, and only three of the six entered over 8days of observation. Five of the 15 ferrets available on the 6000ha study area eluded recapture, although all remained present.

    The resilience of Christchurch, New Zealand's urban forest has been tested during a year of major earthquakes and aftershocks. Tree loss has resulted from mass soil movement, soil liquefaction, rockfalls, and land slips. At the time of writing, only 384 trees have been documented as removed, however, thousands more are scheduled for removal. Additionally, the changes to the soil environment resulting from liquefaction will require existing trees to adapt quickly to their new soil environment. Their fate will not be known for years.

    Much information on restoration and management exists for wet tropical forests of Central America but comparatively little work has been done in the dry forests of this region. Such information is critical for reforestation efforts that are now occurring throughout Central America. This paper describes processes of degradation due to land use and provides a conceptual framework for the restoration of dry tropical forest. Most of this forest type was initially harvested for timber and then cleared for cattle in the last century (1930–1970).

    Simulation of the land subdivision process is useful in many applied and research areas. Planners use such tools to understand potential impacts of planning regulations prior to their implementation. While the credibility of both land-use change and urban growth models would be enhanced by integrating capabilities to simulate land subdivision, such research is lacking in the published literature. Of the few subdivision tools that exist, most are either not fully-automated or are unable to generate realistic subdivision layouts.

    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 irrigation of the 2400ha of flat land within the catchment is an important feature impacting on farm business profitability and stream health. Water quality variables and nutrient and sediment yield estimates are reported for a four-year period.

    The status of many invasive plant species that are also of high commercial value is contentious. Management of negative impacts depends on the support and co-operation of people who regard the species as an asset. For example, buffel grass (Cenchrus ciliaris) is highly prized by many pastoralists in Australia as an introduced pasture grass for livestock but it also has significant and deleterious environmental impacts. Identifying management strategies that minimise environmental impacts yet support production benefits is crucial for achieving sustainable outcomes.

    A multi-stakeholder representative group was established to oversee a project examining the economic and environmental performance of a representative North Island hill country catchment farm at Whatawhata in the western Waikato region of New Zealand. The group included representation from landowners, government agencies and scientists. The group was facilitated through an action research approach incorporating three phases: (1) awareness; (2) forecasting; and (3) implementation.

    This themed issue of Land Use Policy builds on the papers presented at an international symposium entitled Social Dimensions of Market-based Instruments, convened by the Charles Darwin University in Darwin, Australia, in November 2010. The symposium set out to review the extent to which market-based instruments were being employed as social policy tools in various contexts, what challenges achieving relevant social policy objectives posed, what trade-offs arose between environmental, social and economic objectives, and whether and how tensions could be resolved.
