    Expansion of Lifestyle Blocks in Peri-Urban New Zealand: A Review of the Implications for Environmental Management and Landscape Design
    (MDPI (Basel, Switzerland), 2025-07-11) Xie H; Pearson D; McLaren SJ; Horne D
    Lifestyle blocks (LBs) are small rural holdings primarily used for residential and recreational purposes rather than commercial farming. Despite the rapid expansion of LBs over the last 25 years, which has been driven by lifestyle amenity preference and land subdivision incentives, their environmental performance remains understudied. This is the case even though their proliferation is leading to an irreversible loss of highly productive soils and accelerating land fragmentation in peri-urban areas. Through undertaking a systematic literature review of relevant studies on LBs in New Zealand and comparable international contexts, this paper aims to quantify existing knowledge and suggest future research needs and management strategies. It focuses on the environmental implications of LB activities in relation to water consumption, food production, energy use, and biodiversity protection. The results indicate that variation in land use practices and environmental awareness among LB owners leads to differing environmental outcomes. LBs offer opportunities for biodiversity conservation and small-scale food production through sustainable practices, while also presenting environmental challenges related to resource consumption, greenhouse gas (GHG) emissions, and loss of productive land for commercial agriculture. Targeted landscape design could help mitigate the environmental pressures associated with these properties while enhancing their potential to deliver ecological and sustainability benefits. The review highlights the need for further evaluation of the environmental sustainability of LBs and emphasises the importance of property design and adaptable planning policies and strategies that balance environmental sustainability, land productivity, and lifestyle owners’ aspirations. It underscores the potential for LBs to contribute positively to environmental management while addressing associated challenges, providing valuable insights for ecological conservation and sustainable land use planning.

    Hyperspectral Data Can Classify Plant Functional Groups Within New Zealand Hill Farm Pasture
    (MDPI AG, 2025-03-21) Cushnahan T; Grafton M; Pearson D; Ramilan T; Hasenauer H
    Reliable evidence of species composition or habitat distribution is essential to advance pasture management and decision making, including the definition of fertiliser rates for aerial top dressing. This is more difficult in a diverse environment such as New Zealand hill country farms. The simplification of the landscape character using plant functional types and species dominance has proven useful in ecological studies and in modelling grasslands. This study used hyperspectral imagery to map hill country pasture into plant functional groups (PFGs) as a proxy for pasture quality. We validated a farm scale map generated using support vector machines (SVMs), with ground reference data, to an overall accuracy of 88.75%. We discuss how that information can improve on-farm decision making and allow for better coordination with off-farm consultants. This form of farm-wide mapping is also critical for the successful application of variable-rate aerial topdressing technology as input for the allocation of fertiliser rates.

    Integrating ecosystem services with geodesign to create multifunctional agricultural landscapes: A case study of a New Zealand hill country farm
    (Elsevier Ltd, 2023-02) Tran DX; Pearson D; Palmer A; Dominati EJ; Gray D; Lowry J
    An ecosystem-based management approach (EBM) is suggested as one solution to help to tackle environmental challenges facing worldwide farming systems whilst ensuring socio-economic demands are met. Despite its usefulness, the application of this approach at the farm-scale presents several implementation problems, including the difficulty of (a) incorporating the concept of ecosystem services (ES) into agricultural land use decision-making and (b) involving the farmer in the planning process. This study aims to propose a solution to overcome these challenges by utilising a geodesign framework and EBM approach to plan and design a sustainable multifunctional agricultural landscape at the farm scale. We demonstrate how the proposed approach can be applied to plan and design multifunctional agricultural landscapes that offer improved sustainability, using a New Zealand hill country farm as a case study. A geodesign framework is employed to generate future land use and management scenarios for the study area, visualize changes, and assess the impacts of future land use on landscape multifunctionality and the provision of associated ES and economic outcomes. In this framework, collaboration with the farmer was carried out to obtain farm information and co-design the farmed landscapes. The results from our study demonstrate that farmed landscapes where multiple land use/ land cover types co-exist can provide a wide range of ES and therefore, meet both economic and environmental demands. The assessment of impacts for different land use change scenarios demonstrates that land use change towards increasing landscape diversity and complexity is a key to achieving more sustainable multifunctional farmed landscapes. The integration of EBM and geodesign, is a transdisciplinary approach that can help farmers target land use and management decisions by considering the major ES that are, and could be, provided by the landscapes in which these farm systems are situated, therefore maximising the potential for beneficial outcomes.

    Effects of spatial data resolution on the modelling and mapping of soil organic carbon content in hill country grassland landscapes
    (John Wiley and Sons Ltd on behalf of British Society of Soil Science, 2024-01-19) Tran DX; Dominati E; Lowry J; Mackay A; Vibart R; Pearson D; Devantier B; Noakes E
    Limited use has been made of spatially explicit modelling of soil organic carbon (SOC) in highly complex farmed landscapes to advance current mapping efforts. This study aimed to address this gap in knowledge by evaluating the spatial prediction of SOC content in the 0–75 mm soil depth in hill country landscapes in New Zealand (NZ) using point-based training data, along with topographic covariates and Sentinel 2 spectral band ratios using an automated set of machine learning (AutoML) tools in ArcGIS. Subsequently, it also focused on quantifying the effects of spatial data resolution (i.e., 1, 8, 15, and 25 m) in terms of predicted map accuracy. Farmlets with contrasting phosphorus fertilizer and sheep grazing histories located at the Ballantrae Hill Country Research Station, NZ were selected to conduct the research. Six candidate algorithms incorporated in the AutoML tools (i.e., XGBoost, LightGBM, linear regression, decision trees, extra trees, random forest) and ensemble model were utilized to model the spatial pattern of SOC content. The results show that the ensemble model that combine predictions of various algorithms applied for 1 m data resolution enables the highest performance and accuracy (i.e., R2 =.76, RMSE = 0.66%). Among the predictive variables used in the model, slope, wetness, and topographic position indices were found to be the most important topographical features that explain SOC patterns in the study area. Inclusion of spectral indices derived from remote sensing, including surface soil moisture and clay minerals ratio, made further improvement to the SOC content prediction. The study reveals that a decrease in the resolution of the geospatial data does not substantively affect the mean SOC content estimation of a farm-scale modelling. However, using coarser resolution data reduces the ability of the model to predict changes in the spatial pattern of SOC content across a hill country grassland landscape.

    Lifestyle Properties, Ecosystem Services, and Biodiversity Protection in Peri-Urban Aotearoa–New Zealand: A Case Study from Peri-Urban Palmerston North
    (MDPI (Basel, Switzerland), 2021-12-06) Pearson D; Fürst C
    Intensive agriculture and urbanization are putting pressure on natural capital in Aotearoa–New Zealand (NZ), with native ecosystems and water quality suffering degradation. As the population has increased, so development has pushed into the rural–urban fringe. Over the last 30 years, the number of lifestyle properties in NZ has increased dramatically. Many of these properties have been developed on some of NZ’s most productive soils, meaning a loss of provisioning services from this land. However, given their location, these developments present new opportunities for the enhancement and protection of other ecosystem services. This paper presents the findings of an exploratory study conducted on lifestyle block residents in peri-urban Palmerston North. The results showed that these residents have a good sense of environmental stewardship and a desire to plant native species, improve connectivity, and protect their land from the invasion of pests and weeds. These residents are also quite community-focused and protective of their special place. This creates an excellent basis from which to encourage greater collaborative action towards protecting and enhancing biodiversity and to put in place land management strategies that can enhance natural capital and assist in other ecosystem service protection serving to improve the landscape ecology of peri-urban environments.

    Acknowledging Landscape Connection: Using Sense of Place and Cultural and Customary Landscape Management to Enhance Landscape Ecological Theoretical Frameworks
    (MDPI (Basel, Switzerland), 2023-03-23) Pearson D; Gorman J; Albuquerque UP
    Landscapes are important socio-ecological systems. They are widely researched through landscape ecology to aid conservation and environmental management efforts, yet these efforts are not always as successful as they could be in terms of on-the-ground impact. Increasingly when considering conservation, it is being recognized that indigenously managed landscapes have slower rates of biodiversity loss and better environmental outcomes. Local knowledge and connection to the landscape can play a significant part in successfully managing these landscapes. Acknowledging that stewardship of the landscape is more effective when people are a part of the landscape with deep-rooted connection to place is important for understanding the significance of traditional ecological knowledge and the implementation of indigenous-led action. It has also been shown that researchers who have a stronger sense of place and connection to landscapes can also drive initiatives that have better environmental outcomes. This means that human connections to landscapes are important for management strategies, and a better understanding of the human cognition of landscapes is necessary in landscape ecological theoretical frameworks. This review paper explores literature that acknowledges cultural perspectives and cognition of landscapes and how this relates to landscape ecology. It makes recommendations about how landscape ecology can contribute towards better on-the-ground outcomes by embracing more effective mechanisms of collaboration and participation to incorporate local and indigenous knowledge.
