Soil N2O emissions were measured during four seasons from two highly productive grass-clover dairy pastures to assess the influences of soil moisture, temperature, availability of N (NH 4 + and NO 3 – ) and soluble C on N2O emissions, and to use the emission data to validate and refine a simulation model (DNDC). The soils at these pasture sites (Karapoti(More)
1 Despite two decades of effort to curb emissions of CO2 and other greenhouse gases (GHGs), emissions grew faster during the 2000s than in the 1990s1, and by 2010 had reached ~50 Gt CO2 equivalent (CO2eq) yr (refs 2,3). The continuing rise in emissions is a growing challenge for meeting the international goal of limiting warming to less than 2 °C relative(More)
The ecosystem services approach to resource management considers all services provided by ecosystems to all sections of the community. As such, it could be used to assess sustainability of human development and equity in resource use. To facilitate the approach, tools are required at the level of detail at which policy and management decisions are made. We(More)
Environmental impacts associated with the construction, maintenance, and disposal of low-impact stormwater management devices are one aspect that should be considered during decision-making and life-cycle assessment (LCA) is a suitable method for quantifying such impacts. This paper reports a pilot study that employs LCA to compare life-cycle energy(More)
Under the Paris Agreement, parties set and implement their own emissions targets as nationally determined contributions (NDCs) to tackle climate change. International carbon emissions trading is expected to reduce globalmitigation costs. Here, we show the benefit of emissions trading under both NDCs and amore ambitious reduction scenario consistent with the(More)
This chapter reviews all stocks and fl uxes of carbon in New Zealand, and reviews biophysical regulation through surface albedo. The terrestrial environment provides a climate-regulation service by assimilating, transforming, and adjusting to emissions of greenhouse gases that could otherwise lead to undesirable changes in global climate. Quantifying this(More)
Central and local government agencies in New Zealand are calling for a paradigm shift in natural resource management. A unified approach is required to deliver a wide range of services and outcomes in a sustainable manner. Our new, 4-year research project aims to provide the scientific basis for such an approach. We are taking a threephase approach. First,(More)
A distributed water balance model is used to simulate the soil moisture regime of the Motueka catchment. The model is a major simplification of the Distributed HydrologyeVegetationeSoil Model (DHVSM) with modifications suitable for the study area. The model was applied at 25-m resolution with a 1-day time-step for 10 years. The simulated hydrograph showed(More)
