Special Issue Information

Dear Colleagues,

Conventionally designed homogenous agricultural systems characterized by a high reliance on agrichemicals and low species richness are often associated with environmental degradation and low resilience to environmental and economic impacts. In response, farmers are internationally shifting to greener production practices in response to growing demands from governments, retailers, and consumers. Much has been written about efficiency/substitution farming strategies to reduce the impact of concern to regulators by increasing input efficiencies and substituting more environmentally benign system components. Much less is known about biodiversity farming strategies, such as the restoration of green infrastructure (GI) on farms and across farming landscapes. These strategies can not only play a significant role in reducing the environmental impacts of farms, but they can also provide other benefits efficiency/substitution strategies cannot provide. GI is defined as the multi-scaled networks of vegetation and waterways on farms, and across their landscapes, that provide key ecosystem services to growers, communities, and markets. It may consist of cover crops, shelterbelts or hedgerows, riparian corridors, vegetation around homes or cellar doors, and remnant natural areas. Benefits can include improved product yields, reduced incidence of pests and weeds, improved microclimates, cleaner water, and improved support for indigenous wildlife and vegetation communities.

This Special Issue brings together leading research that introduces or advances innovative approaches in the use of GI on farms and across agricultural landscapes, on both private and public land.

We invite research, methods, systematic reviews, and critical discussion papers on new ideas that deal with novel design, planning policy, governance, implementation, and management approaches on, but not limited to, the following topics:

  • How can green infrastructure on farms be designed and planned to maximize multiple benefits to growers, such as pest and weed regulation, microclimate mitigation, product sales and branding, agri-tourism, and resilience to environmental or economic impacts?
  • How can green infrastructure across farming landscapes be designed and planned to maximize support for publicly valued ecosystem services, such as catchment water quality, climate change-related flooding, and landscape scale biodiversity?
  • What are the disservices of green infrastructure and how can they be minimized?
  • How can the implementation and management of green infrastructure be improved to improve its cost-effectiveness?

We look forward to receiving your contributions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

New Zealand’s agricultural sector faces the challenge of maintaining productivity while minimizing impacts on freshwaters. This study evaluates the cost-effectiveness of various green infrastructure systems designed to reduce diffuse agricultural sediment and nutrient loads. Utilizing a quantitative economic and contaminant reduction modeling approach, we analyze the impacts of five interceptive mitigation systems: riparian grass filter strips, constructed wetlands, woodchip bioreactors, filamentous algal nutrient scrubbers, and detainment bunds. Our approach incorporates Monte Carlo simulations to address uncertainties in costs and performance, integrating hydrological flow paths and contaminant transport dynamics. Mitigation systems are assessed individually and in combination, using a greedy cyclical coordinate descent algorithm to find the optimal combination and scale of a system for a particular landscape. Applying the model to a typical flat pastoral dairy farming landscape, no single system can effectively address all contaminants. However, strategic combinations can align with specific freshwater management goals. In our illustrative catchment, the mean cost to remove the full anthropogenic load is NZD 1195/ha for total nitrogen, NZD 168 for total phosphorus, and NZD 134 for suspended solids, but results will vary considerably for other landscapes. This study underscores the importance of tailored deployment of green infrastructure to enhance water quality and support sustainable agricultural practices. Full article

Wine grape ecosystems with low species richness and reliance on agrichemicals have weak resilience to environmental impacts. Increasing biodiversity through green infrastructure (GI) not only helps mitigate some of these impacts but can provide additional benefits to growers and the public. Despite this, many vineyards have limited GI. While scholars suggest incentive programmes may help to encourage GI implementation, few studies have evaluated their effectiveness. We surveyed winegrowers and their vineyards in the Waipara Valley sub-region, New Zealand, to evaluate an incentive programme aimed at increasing GI on vineyards, particularly indigenous vegetation. The results indicated the programme was effective in encouraging growers to plant indigenous plants in areas incapable or unsuitable for growing grapes, largely in support of nature conservation, aesthetics, branding, and sales. It was less successful in encouraging growers to plant them in productive areas. While substantial GI, primarily in the form of inter-row cover crops, was managed in these areas, most were exotic plants seen by growers to provide superior services (especially erosion control, weed suppression and pest regulation) at lower management complexity and cost. Growers identified six GI enablers: (1) promoting GI types that provide greater grower services than disservices and costs of implementation and management; (2) implementing GI where biophysical conditions support success; (3) providing assistance with plant selection and design; (4) providing GI implementation and/or management funding; (5) developing GI certification policies and regional association programmes; and (6) providing government GI regulations, strategies, and incentives. They also identified five barriers: (1) insufficient grower appreciation for indigenous GI services; (2) grower concerns that some GI disservices were greater than their services; (3) grower belief that costs of GI implementation and/or management were greater than those of alternative practices; (4) harsh and remote GI growing conditions; (5) lack of grower knowledge regarding how to design plantings, especially those that could provide multiple services; and (6) lack of sufficient financial resources for GI implementation and/or management. Twenty recommendations for improving GI implementation are provided. Full article
