The National Policy Statement for Freshwater Management (NPS-FM) establishes the need to set and manage water resources within limits. This report is the first national assessment of the indirect impacts of the NPS-FM on New Zealands greenhouse gas emissions (GHGs). The water quality improvement aspect of New Zealands freshwater reforms are expected to drive significant changes in land and water management across the country. Emissions benefits through the freshwater reforms could potentially result in significant savings for New Zealand by starting the transition to low emissions in the agricultural sector and helping to achieve New Zealands overall climate goals. For farmers, changes in land use and management to meet water quality targets will reduce their potential future exposure to needs to reduce GHG emissions. GHG emissions reductions are a combination of reduced emissions through changes in management and de-stocking and increased carbon sequestration associated with planting riparian buffers or afforesting part of the farm. Key results are that without land use change, agricultural GHGs (primarily methane and nitrous oxide) could be reduced by 2.4% or 0.82 million metric tonnes of carbon-dioxide equivalent per annum (MtCO2e/yr) along with an additional 0.11 MtCO2e of forest carbon sequestration as a result of planting riparian buffers and pole planting for erosion control (for a net reduction of 0.92 MtCO2e/yr or 13%). If afforestation is perceived to be a feasible freshwater mitigation option, up to 800 000 ha of additional trees could be planted, thereby increasing carbon sequestration by 5.4 MtCO2-e/yr. In this case gross (net) GHGs could be reduced by 2.9 (8.2) MtCO2e/yr, primarily through reduction in stock numbers and increases in forest carbon sequestration. This option could reduce net emissions by nearly 80%. The majority of the emissions impact occurs in the sheep and beef sector, with a gross (net) reduction of 0.61 (0.72) MtCO2e/yr. Nitrogen targets most strongly drive on-farm GHG reductions for all the modelled scenarios that limit mitigation to on-farm changes. This is primarily because actions to mitigate N are most closely related to practices that can also mitigate GHGs (e.g. stock management).

“…Enhancing agricultural productivity without eroding natural resources is essential to sustain economic development (Koohafkan et al, 2012). In New Zealand, several studies have shown the environmental consequences of agricultural activity and its effects on social wellbeing (Monaghan et al, 2007;Daigneault et al, 2016;Fernandez & Daigneault, 2017). Public regulatory bodies have established enabling legislation, such as the Resource Management Act 1991 and Climate Change Response Act 2002, to ensure effective management of natural resources and to meet New Zealand's international environmental obligations (MFE, 2017).…”

“…Although the dairy industry plays a vital role in the New Zealand economy, it also generates significant environmental externalities. The percentage of greenhouse gas (GHG) emissions, nitrogen (N) leaching, and phosphorous (P) loss in New Zealand due to dairy farming is estimated at 36.8%, 35%, 11.4%, respectively of NZ's total emissions and nutrient leaching, despite using just 7% of the land area (Daigneault et al, 2016). Environmental pressures that result from the dairy sector economic activities could, therefore, greatly affect surrounding ecosystem services and biodiversity.…”

The dairy industry is a significant contributor to the New Zealand economy. Improving dairy productivity while meeting appropriate environmental standards is necessary if the New Zealand economy is to grow sustainably. In this paper, a two-stage data envelopment analysis (DEA) technique was employed to assess the combined environmental and economic performance of dairy farms (i.e., eco-efficiency). A sample of 108 farms from a survey carried out in 2011-12 across all regions of New Zealand was used to analyse the eco-efficiency of dairy farms. Survey data on milk solid production was used to estimate economic performance, while data on greenhouse gas (GHG) emissions and nutrient leaching were used to estimate environmental performance. Other information in the survey such as geophysical characteristics and management practices that could indirectly affect the eco-efficiency of the dairy farms was also incorporated in the analysis. In the first stage of our analysis, an eco-efficiency score for each farm was estimated using directional distance function with restrictions in environmental outputs. In the second stage, the effect of the geophysical characteristics and management practices on the calculated eco-efficiency scores were then estimated using an integrated truncated regression and bootstrapping procedure. The results show that, on average, a reduction of 27% in environmental externalities was possible while maintaining the same level of output. GHG emissions, nitrogen leaching, and phosphorous loss were excessive and inefficient. Adopting irrigation and on-farm management practices (e.g., feedpad, in-shed feeding, and wintering-pad) improved efficiency. The few dairy farms located on hilly or sloped land were found to be less efficient than those on flat land. Environmental policies applied to dairy sector have the potential to reduce GHG emission, nitrogen leaching, and phosphorous loss by 3.45 million tonnes, 20,610 tonnes, and 366 tonnes, respectively.
