A practical model of what conditions, capabilities and resourcing are necessary for collaboration to be successful, to be used in designing, evaluating or improving collaborative processes. This model was co-developed with collaboration practitioners across New Zealand.
For OLW research, there are six criteria that are the most important for ensuring indicators are useful. Fit-for-purpose indicators are: accepted by stakeholders, valid, clearly defined and standardised, based on available or easily accessible data, easily communicable, performance-based.
Fate Factors (FFs) for use in life-cycle analysis (PCA) were developed for both dissolved inorganic nitrogen (DIN) and dissolved inorganic phosphorus (DIP), distinguishing emissions from soil and emissions to freshwater. The use of these FFs, in conjunction with a spatially explicit inventory of DIN and DIP emissions, improves the environmental relevance and discriminatory power of the assessment of freshwater eutrophication impacts for LCA applications internationally.
Exporters and agri-food marketers can use this meta-analysis (combining the results of 94 other studies) to learn how much more consumers are willing to pay for attributes such as organic dairy (36% more, for this example). This analysis found that Australasian consumers value red meat products with credence attributes the highest, followed by Asian, European and North American consumers. As for dairy products, willingness-to-pay is highest in the Asian market, followed by the EU and the North America.
Maps of the potential groundwater recharge zones across New Zealand (500m x 500m resolution), which can be used to identify areas of high nutrient leaching in zones where high groundwater recharge potential exists.
NIWA’s Catchment Land Use for Environmental Sustainability (CLUES) model is a GIS-based modelling system that assesses the effects of land use change on water quality and socio-economic indicators. CLUES allows users to create both land use and farm practice change scenarios (stocking rates, mitigation), providing results in map and tabular displays. NIWA can provide training.
Soil conservation over large areas is expensive and needs to be targeted to obtain maximum benefit for the least cost. Cascade of Soil Erosion research has outlined an event-based model of soil erosion and sediment transport at the catchment scale.
The NZ Sustainability Dashboard has been comprehensively reviewed by our Indicators Working Group and found to be fit-for-purpose. The dashboard provides processes and tools to enable effective sustainability assessment and reporting across different agricultural sectors.
The Indicators Working Group produced this proof-of-concept dataset for 4 rural towns in New Zealand, demonstrating the possibility of hosting research data for general access on a public data repository. This data presents indicators related to the resilience of rural communities (Dannevirke, Huntly, Taumaruniu and Te Kuiti), collected from publicly available official statistics and surveys.
A stocktake of existing work on agri-environmental indicators relevant for Our Land and Water was completed by the Indicators Working Group. Some of these focus on environmental linkages, while others focus on economic and production data. The projects listed cover Government projects, industry projects and science projects.
The Matrix of Drivers provides market intelligence and foresight into consumer trends and international agreements. Industry bodies can use this research to assess the magnitude of drivers affecting their sector (eg climate change, plant-based protein trends), anticipate change, and assist producers to adapt. Primary sector producers and entrepreneurs can use The Matrix to meet market demands or seek out new high-value, low-footprint opportunities, and avoid lurching from one trend to the next. See table 3.1 in the report.
A model of soil erosion developed for the Manawatū-Wanganui by Cascade of Soil Erosion researchers can be parameterised with local data, then used in spreadsheet form to evaluate the impact of changes to land use and management on the sediment yield of catchments, and help regional councils plan cost-effective soil conservation work projects of varying size and complexity.
Sources and Flows research modelled drought duration-severity distribution and frequency to generate SDF curves for six locations in different climatic regions. Modelling of soil drainage at these sites indicated 35% to 80% more drainage peaks than expected, suggesting better monitoring of soil moisture and scheduling of irrigation is required. The SDF curves provide a comprehensive understanding of occurrence and duration of dry conditions, and can be a useful tool for developing strategies for water management.
Sources and Flows research identified 5 potential groundwater recharge zones across New Zealand. Knowledge of groundwater recharge potential is required for sustainable groundwater management, including the assessment of vulnerability to contamination. The maps can be used to identify areas of high nutrient leaching in zones where high groundwater recharge potential exists (regions with large lakes and in the lower elevation plains).
Assessing Contaminants with Stream Order research discovered that fencing only large streams to exclude stock has less effect on freshwater quality than expected. Small, steeply sloping streams contribute, on average, 77% of the load of freshwater contaminants. To substantially reduce contaminant losses, stock should be excluded from small, steeply sloping streams. This research can be used by local government to determine policy to improve the quality of fresh water.
