Harnessing Nanomaterials for Enhanced Energy Efficiency in Transpired Solar Collectors: A Review of Their Integration in Phase-Change Materials

The building sector plays an important role in the global climate change mitigation objectives. The reduction of CO2 emissions and energy consumption in the building sector has been intensively investigated in the last decades, with solar thermal energy considered to be one of the most promising solutions due to its abundance and accessibility. However, the discontinuity of solar energy has led to the study of thermal energy storage to improve the thermal performance of solar thermal systems. In this review paper, the integration of various types of phase-change materials (PCMs) in transpired solar collectors (TSC) is reviewed and discussed, with an emphasis on heat transfer enhancements, including nanomaterials. Thermal energy storage applied to TSC is studied in terms of design criteria, materials technologies, and its impact on thermal conductivity. This review highlights the potential of nanomaterial technology integration in terms of thermal performance improvements. The utilization of nanomaterials in solar walls holds the potential to significantly enhance their performance. The integration of diverse materials such as graphene, graphite, metal oxides, and carbon nanoparticles can pave the way for improving thermal conductivity.

Participatory Policy Packaging for Transport Backcasting: A Pathway for Reducing CO2 Emissions from Transport in Malta

Significant emission reductions are needed in the transport sector to reach climate change mitigation objectives. Backcasting, a type of scenario-analysis approach, is a useful tool for the analysis of possible alternative transport futures and strategies to arrive at these futures when the business-as-usual projection is no longer sustainable. The backcasting approach consists of establishing desirable futures and examining the pathways by which those futures can be reached. This paper focuses on the policy packaging phase of a transport backcasting study carried out in the context of Malta as a case study. The aim of this paper is to contribute to the existing literature on transport and climate change using the case of Malta, which presents a context of high dependency on private cars and difficulty in transitioning to sustainable mobility. This paper tests the usefulness of a practice-based approach to transport backcasting. The results of this backcasting framework are a set of climate policies that target different elements of mobility practices and suggest that interventions for sustainable mobility should go beyond transport and target other spheres of social life. Collaboration between stakeholders and participation of citizens during the backcasting process was key to making the policy design process more participatory. Results of this study show how new approaches can open possibilities for a transition towards more sustainable mobility and contribute to widening the knowledge in the field of transport backcasting studies.

The role of LCA in the renovation’s early decision-making for the design of a multifunctional, modular building envelope system

The renovation of buildings has a high capacity to influence the environmental impacts and global objectives of climate change mitigation. In the context of designing low-energy buildings with minimized environmental impacts, the life cycle assessment (LCA) has been proven a straightforward method, to evaluate the direct and indirect environmental impacts of a building concept. Even though it is the most energy-intensive element, the use phase is not only a source of environmental concern but also the whole life cycle of the building and its components. However, energy-efficient renovation decisions tend to be financially motivated events, subject to exogenous constraints or barriers, that do not integrate whole life cycle thinking. This study aims to identify how the LCA information can be considered in comparing renovation options. compare renovation options, taking into account the modular envelope system developed as part of the European research project ENSNARE (ENvelope meSh aNd digitAl framework for building Renovation) case study. The study analysed different renovation scenarios, generated according to combinations of renewable energy sources and compare them to the base case and typical renovation scenario. Such information can support the design team in making decisions that consider the whole building and its components’ life cycles.

Decarbonization Strategies in the UAE Built Environment: An Evidence-Based Analysis Using COP26 and COP27 Recommendations

The urgency of addressing climate change is increasingly evident through the rise in devastating natural disasters and significant shifts in global temperatures. With the urbanization of rural landscapes to accommodate population growth, the built environment has emerged as a major contributor to climate change, accounting for approximately 40% of natural resource consumption and carbon emissions. In pursuit of tackling climate challenges, countries have united under the United Nations Framework Convention on Climate Change (UNFCCC) to develop strategies for climate action and adaptation, through the Conference of the Parties (COP). The UAE has been an active member of the COP and has been at the forefront of implementing decarbonization strategies. This paper aims to provide a comprehensive analysis of the decarbonization recommendations presented during COP26 and COP27, specifically focusing on the built environment sector. The primary objective is to highlight how recommendations were effectively incorporated into the UAE’s built environment sector, employing a case study approach further highlighting the specific implementation strategies adopted in the G+2 SEE Institute building while demonstrating how COP26, COP27, and the UAE’s National Climate Change Plan 2017–2050 recommendations were translated into practical measures. The study places particular emphasis on the areas of energy, water and waste management, investigating how these strategies were integrated to promote decarbonization efforts. By examining the G+2 SEE Institute building case, this research attempts to provide valuable insights on aligning built environment practices with climate change mitigation objectives. The planning of the building structure employed a systems thinking approach, while assessments were conducted to identify materials and designs that would enable the building to achieve net-zero status. Real-time data analysis was employed for comprehensive analysis. The findings of this study will contribute to the body of knowledge on sustainable construction practices and serve as a guide for stakeholders, including developers, policymakers, and practitioners, in adopting effective strategies in reducing carbon emissions and fostering environmental sustainability in line with the Paris Agreement.

Will farmers go electric? How Dutch environmental regulation affects tractor purchase motivations and preferences

Farm machinery management can contribute to European agricultural, energy and environmental policy objectives of climate change mitigation and fossil fuel independence by investing in tractor electrification. However, many farmers in the Netherlands (and beyond) have expressed concerns about the future profitability and ability to produce at reasonable costs. The Netherlands is also in a so-called ‘nitrogen crisis’, which further causes policy uncertainty about the introduction of more environmental regulations for nitrogen abatement. We conducted a best-worst scaling survey experiment to elicit preferences for electric tractor attributes and measured attitudes towards environmental regulation using motivational posture theory. The ranking of and correlations across estimated preferences and the purchase intention show that the 156 dairy and arable farmers surveyed evaluated an investment in an electric tractor as not feasible. Another conclusion is that the breakthrough of electric tractors is affected by negative anticipated emotions and feelings concerning the current environmental policy and regulatory context.

Reducing US biofuels requirements mitigates short-term impacts of global population and income growth on agricultural environmental outcomes

Biobased energy, particularly corn starch-based ethanol and other liquid renewable fuels, is a major element of federal and state energy policies in the United States. These policies are motivated by energy security and climate change mitigation objectives, but corn ethanol does not substantially reduce greenhouse gas emissions when compared to petroleum-based fuels in all production scenarios. Corn production also imposes substantial negative externalities (e.g., nitrogen leaching, higher food prices, water scarcity, and indirect land use change). In this paper, we utilize a partial equilibrium model of corn-soy production and trade to analyze the potential of reduced US demand for corn as a biobased energy feedstock to mitigate increases in nitrogen leaching, crop production and land use associated with growing global populations and income from 2020 to 2050. We estimate that a 24% demand reduction would sustain land use and nitrogen leaching below 2020 levels through the year 2025, and a 41% reduction would do so through 2030. Outcomes are similar across major watersheds where corn and soy are intensively farmed.

CO2 Sequestration Overview in Geological Formations: Trapping Mechanisms Matrix Assessment

This review focuses on the consequences of the early and rapid deployment of carbon dioxide (CO2) capture and storage (CCS) technologies, which is currently recognized as a critical problem in fulfilling climate change mitigation objectives and as a viable alternative for countries throughout the world. Currently, the geological storage of CO2 is the most effective and, in many cases, the only viable short- to medium-term alternative for considerably moving towards CO2 sequestration in geological sinks and, thus, lowering net carbon emissions into the atmosphere. Furthermore, this review explores the global and environmental measurements of CO2 emissions, as well as the emphasis behind more efficient energy usage. The components of the CCS system are briefly examined, with an emphasis on the technologies that have been developed by previous scholars to support carbon capture, as well as the kinds of carbon geological formations that are suitable sinks for CO2. Additionally, the importance of carbon interaction and sequestration in unconventional formations are examined through case studies that are applied to coalbed seams and shale gas reservoirs. Numerous trapping processes are grouped and introduced in a constructive matrix to easily distinguish the broad trapping mechanisms, which are (1) chemical, (2) physicochemical, and (3) physical trapping, and each of these categories are further classified in depth based on their contribution to CO2 storage.

A life cycle assessment method to support cities in their climate change mitigation strategies

National climate change mitigation objectives must be translated to the city level and to specific sectors, with locally-relevant policy measures. However, assessing the decarbonization value of these measures is a challenge for local policy makers and few local consumption assessment studies integrate a systemic vision. This research presents a multi-criteria city-scale Life Cycle Assessment method focusing on the three largest carbon-emitting sectors in cities: food, residential buildings and daily mobility, with an original combination of databases and models. For food, databases were used to evaluate environmental impacts based on socio-demographic characteristics. For building and mobility, modeling tools were used and adapted at different scales: with local spatial refinement for mobility and the creation of archetypes representing the city's most common residential buildings. A demonstration of this new cross-sectoral method was conducted on Montreuil city in the Parisian region, to (1) evaluate the current greenhouse gas emissions (GHG), and (2) test the possible reductions following different measures. The developed assessment framework provides various interpretation, with disaggregated contribution, mapping, and scenario analysis. For instance, the application of ambitious measures and important lifestyle changes reduced GHG in these sectors by 30%, far from the French government's ambitions of a 55% reduction by 2030.

Assessing the synergies and trade-offs of development projects in response to climate change in an urban region

A synthesis of the complex relationships, including synergies and trade-offs, between urban development projects and climate change mitigation and adaptation objectives can ensure that all these relationships are taken into consideration. We used a systems approach and applied an impact matrix and chain effect analysis methods to projects in the highly urbanized Taipei metropolitan region to identify the influences and effects between urban development projects and climate change objectives. Three types of urban plans and projects were analyzed: flood control, transportation, and urban planning. The magnitudes of the influences and effects between these projects and plans were derived through interviews with experts familiar with Taipei's urban development. This pilot study found no synergy in the response to climate change mitigation and adaptation for the urban development projects analyzed. The current standalone policies and plans related to urbanization in Taipei have resulted in trade-offs for flood control and public transit projects because they contribute positively toward one climate objective but negatively impact another. A high-level policymaking mechanism that ensures coordination and collaboration between different sectors is needed to supervise sectoral policies. Prior to the approval and implementation of a plan, policymakers should request the assessment of synergies and trade-offs between plans and projects to ensure a synergistic effect to climate change issues. This study confirms that the strategy from individual sector in a metropolitan region will result in trade-off between climate change issues is a global problem. This paper also strengthens the concept that the assessment of synergy/trade-offs between policy and plans should be conducted using systemic approach.

Existing evidence on the impacts of within-field farmland management practices on the flux of greenhouse gases from arable cropland in temperate regions: a systematic map

BackgroundReducing the emissions of greenhouse gases (GHGs) is vital for mitigating climate change and meeting commitments to international agreements such as the COP 21 Paris Agreement of 2015. Agriculture is reported to account for approximately 11 percent of total global GHG emissions such that: the agricultural sector has an important role to play in meeting climate change mitigation objectives. However, there is currently little consensus on how farm management and interventions, along with interactions with in-field variability, such as soil type, affect the production and assimilation of GHGs in arable crop lands. Practical recommendations for farmers are often vague or generalised, and models (e.g. on the amount of nitrogen fertiliser applied) are used despite limited understanding of the influence of local conditions, such as the importance of soil type. Here, we report the findings of a systematic map of the evidence relating to the impact on GHG flux from the in-field management of arable land in temperate regions.MethodsWe searched for, collated and catalogued research relating to the effects of in-field arable farming practices in temperate systems on GHG emissions. Results from 6 bibliographic databases, a web-based search engine and organisational websites were combined with evidence from stakeholders. Duplicates were removed and the results were then screened for relevance at title and abstract, and full-text levels according to a predefined set of eligibility criteria (following consistency checking). Relevant studies were then coded and their meta-data extracted and used to populate a systematic map database describing each study’s settings, methods and measured outcomes.ResultsThe mapping process identified 538 relevant studies from 351 articles. Nearly all of these (96%) were found from traditional research papers, with 42% from European countries and nearly half (203 studies) lasting for 12 months or less. Over half of all studies (55%) investigated multiple interventions with chemical fertiliser (n = 100), tillage (n = 70), and organic fertiliser (n = 30) the most frequently studied single intervention types. When combining individually studied and multiple interventions, the top three intervention types most frequently studied were: chemical fertiliser (n = 312); organic fertiliser (n = 176) and tillage (n = 158). Nitrous oxide was the most commonly studied outcome, with over double the number of studies compared to carbon dioxide, the next most studied outcome. Sandy loam and silty loam were the most commonly studied soils but there was a good distribution of studies across other types. However, studies predominately focused on humid sub-tropical (Cfa) and temperate oceanic (Cfb) climates, with hot summer Mediterranean (CSa) and warm summer Mediterranean (Csb) climate zones less represented.ConclusionsThe mapping process identified clusters of research for chemical and organic fertiliser especially in relation to nitrous oxide emissions and for both carbon dioxide and nitrous dioxide in relation to tillage. Therefore, there is potential for further synthesis for these interventions. The spread of research across soil textures and in the humid sub-tropical and temperate oceanic climates may enable further synthesis to provide tailored in-field advice for farmers and provide an evidence base to inform subsidies policy. However, smaller amounts of research relating to biochar, cover crops, crop rotation, and nitrogen inhibitors highlight gaps where further research would be beneficial.

Effects of Silvicultural Adaptation Measures on Carbon Stock of Austrian Forests

We present the results of a simulation experiment that evaluated three scenarios of forest management in the context of climate change mitigation. Two scenarios refer to climate change adaptation measures. The third scenario was a business-as-usual scenario representing the continuation of current forest management. We wanted to know whether a change in tree species composition or the implementation of shorter rotation cycles is in accordance with the objectives of climate change mitigation. Our simulation experiment was based on data of the Austrian National Forest Inventory. A forest sector simulation model was used to derive timber demand and potential harvesting rates. Forest dynamics were simulated with an individual-tree growth model. We compared carbon stocks, harvesting rates, current annual increment, salvage logging, and forest structure. Compared to the business-as-usual scenario, a change in tree species composition and shorter rotation cycles reduce salvage logging by 14% and 32%, respectively. However, shorter rotation cycles reduce the carbon stock by 27%, but increase the harvesting rate by 4.8% within the simulation period of 140 years. For changes in the tree species composition, the results were the opposite. Here, the carbon stock is increased by 47%, but the harvesting rate is reduced by 15%. Thus, there are clear tradeoffs between the different ecosystem services depending on the climate change adaptation scenario. We also show that a fundamental change in forest management must be accompanied by a transformation in wood processing technology and innovation in wood utilization.

Modelling greenhouse gas emissions of cacao production in the Republic of C\xf4te d\u2019Ivoire

The current expansion of cacao cultivation in the Republic of Côte d’Ivoire is associated with deforestation, forest degradation, biodiversity loss and high greenhouse gas (GHG) emissions. Global concerns about emissions that are associated with tropical commodity production are increasing. Consequently, there is a need to change the present cacao-growing practice into a more climate-friendly cultivation system. A more climate-friendly system causes lower GHG emissions, stores a high amount of carbon in its standing biomass and produces high cacao yields. GHG emissions and carbon stocks associated with the present cacao production, as assessed in 509 farmers’ fields, were estimated by using the Perennial GHG model and the Cool Farm Tool. On average, the production of 1 kg cacao beans is associated with an emission of 1.47 kg CO2e. Deforestation contributed largely to GHG emissions, while tree biomass and residue management contributed mainly to carbon storage. The collected data combined with the model simulations revealed that it is feasible to produce relatively high yields while at the same time storing a high amount of carbon in the standing biomass and causing low GHG emissions. The climate-friendliness of cacao production is strongly related to farm management, especially the number of shade trees and management of residues. Calculated emissions related to good agricultural practices were 2.29 kg CO2e per kg cacao beans. The higher emissions due to the use of more agro-inputs and other residue management practices such as recommended burning of residues for sanitary reasons were not compensated for by higher yields. This indicates a need to revisit recommended practices with respect to climate change mitigation objectives.

Data Science and Energy: Some Lessons from Europe on Higher Education Course Design and Delivery

Data science is seen as a key enabler for technologies that help decarbonize global energy use. However, the energy sector continues to struggle to attract and train enough data scientists. The primary reason for this is the lack of emphasis on data science in most graduate programs in energy engineering, and the high barriers of entry for data scientists from other sectors. In this article, we present a snapshot of the data science–related curriculum being taught in graduate energy programs in four different European universities as well as include feedback we received from students and alumni of these programs. While knowledge of data science remains low across the board, students in these programs already recognize data science as an important element of their future professional careers. We also present findings from running three separate iterations of an energy data science course we developed in light of this feedback—one of these iterations was offered only in KU Leuven (Belgium), while the other two were accessible to students at all four universities. In the article, we also discuss challenges and opportunities arising from designing and delivering courses in a cross-university context. This foundational course and others like it are seen as a necessary means to enable students to take more specialized courses in data science, and eventually contribute toward realizing a sustainable energy transition and meeting climate change mitigation objectives.

Integrating climate change impact in new building design process: A review of building life cycle carbon emission assessment methodologies

Life-Cycle Carbon Emission Assessment (LCCO2A) of buildings integrating climate change impact has received increasing attention by researchers as the consequences of climate change become more apparent. It is crucial to integrate the indicator of life cycle carbon equivalent greenhouse gas (GHG) emissions at the early design stage combined with a life cycle assessment, to ensure the elimination of GHG emissions from a building, for its entire life. LCCO2A can provide the necessary information required for reducing carbon emissions of the buildings sector both systematically and comprehensively; however, the lack of a unified assessment framework has prevented the LCCO2A from being utilised as a common daily decision-support tool for sustainable design. This paper will take a retrospective approach when reviewing the methodologies of building LCCO2A in order to facilitate sustainable collective building design which incorporates GHG emission reduction objectives. The paper discusses a wide array of issues concerning LCCO2A and will demonstrate solution methods, as addressed in the extensive existing literature examined in the review and will attempt to establish an effective framework for life cycle carbon assessment. The implication of promoting sustainable designs which incorporate climate change mitigation objectives at the design phase together with the need for climate change policies to facilitate such processes, are also discussed.

Environmental sustainability of future aquaculture production: Analysis of Singaporean and Norwegian policies

To address global food demand and sustainability challenges, aquaculture has appeared as an essential element in food systems, and an increasing number of national aquaculture policies have emerged over the past decades. However, several of these policies have failed because of an often-argued inability to anticipate their far-reaching implications on environmental and socio-economic variables. To tackle this gap, we propose a step-wise framework to assess the national environmental impacts from aquaculture industries with a prospective and systemic approach. Starting from identifying policy-based national targets, the methodology relies on economic equilibrium modeling to develop realistic future-oriented scenarios of the aquaculture sector, and couples them with life cycle assessment principles. To evidence its operability, we apply the framework to two distinct case countries: Norway and Singapore. Beyond our key findings from the analyses of the policies in both countries, we observed that feed production and usage are important drivers of impacts, hence calling for new and more environmentally-friendly feed options. Our results additionally show that the development of aquaculture following existing governmental policies may not directly reduce greenhouse gases emissions and, hence, not support climate change mitigation objectives. These findings should however be cautioned as potential shifts of diets due to the increasing seafood availability might occur, leading to indirect environmental benefits. We therefore advocate the further expansion of our framework to cover the entire food system, so it can integrate such indirect effects. Meanwhile, we recommend its interim application to support policy-making and help move towards more environmentally sustainable aquaculture systems.

Co-benefits and trade-offs of climate change mitigation actions and the Sustainable Development Goals

In addition to driving mitigation of greenhouse gas emissions, climate change mitigation actions can deliver non-climate benefits (co-benefits) but can also have adverse side-effects, working counter to other development objectives. Co-impacts assessment seeks to identify these co-benefits and adverse side-effects. Understanding of co-impacts can provide the knowledge base to garner support for mitigation actions, and to plan interventions that realize synergistic opportunities and contribute simultaneously to multiple objectives, increasing the efficiency and cost-effectiveness of climate actions. However, the value of this information is determined by the manner in which it is framed and communicated. In this paper, the relationships between climate change mitigation action and co-impacts and the Sustainable Development Goals (SDGs) are explored and illustrated using a selection of examples from countries’ Nationally Determined Contributions (NDCs). We suggest that in the context of SDGs, the co-benefits approach could provide a cohesive framing to incentivize stakeholders to work together to garner support for ambitious policy which simultaneously achieves climate change mitigation and non-climate objectives. Similarly, understanding of adverse side-effects can help to ensure that trade-offs with delivery of the SDGs arising from mitigation actions are recognised and minimised. We note that the best way of framing these concepts is context and application specific.

Psychological Factors Influencing Pro-environmental Behavior in Developing Countries: Evidence From Colombian and Nicaraguan Students.

Identifying the determinants of human behavior is useful to adjust interventions and lead the civil society toward a stronger commitment to climate change (CC) mitigation and adaptation objectives, achieving greater support for successfully implementing environmental policies. Existing research has largely focused on case studies of pro-environmental behaviors (PEBs) in developed economies but there is very little evidence for developing countries. This study provides estimations of the effect of internal factors, such as sociodemographic variables, and four psychological dimensions (CC knowledge, environmental attitudes, self-efficacy, and trust in sources of environmental information) on PEBs. Data were obtained through a survey applied with future decision makers – university students – from Colombia (n = 4,769) and Nicaragua (n = 2,354). Indices were generated for PEBs and the psychological dimensions using z-scores and Principal Component Analysis (PCA). Partial correlations were evaluated through the Ordinary Least Squares (OLS) method. Our results suggest that, in order to reach the planned emission reduction targets, policy approaches should more strongly focus on educating and motivating citizens and prepare them for contributing to the environmental cause, as well as provide individual solutions to combat CC, rather than providing only information on its causes and consequences.

GHG displacement factors of harvested wood products: the myth of substitution

A common idea is that substituting wood for fossil fuels and energy intensive materials is a better strategy in mitigating climate change than storing more carbon in forests. This opinion remains highly questionable for at least two reasons. Firstly, the carbon footprints of wood-products are underestimated as far as the “biomass carbon neutrality” assumption is involved in their determination, as it is often the case. When taking into account the forest carbon dynamics consecutive to wood harvest, and the limited lifetime of products, these carbon footprints are time-dependent and their presumed values under the carbon neutrality assumption are achieved only in steady-state conditions. Secondly, even if carbon footprints are correctly assessed, the benefit of substitutions is overestimated when all or parts of the wood products are supposed to replace non-wood products whatever the market conditions. Indeed, substitutions are effective only if an increase in wood product consumption implies verifiably a global reduction in non-wood productions. When these flaws in the evaluation of wood substitution effects are avoided, one must conclude that increased harvesting and wood utilization may be counter-productive for climate change mitigation objectives, especially when wood is used as a fuel.

The Role of Innovation in Industry Product Deployment: Developing Thermal Energy Storage for Concentrated Solar Power

Industries with fast-developing technologies and knowledge-intensive business services rely on the development of scientific knowledge for their growth. This is also true in the renewable energy industry such as in concentrating solar power (CSP) plants, which have undergone intense development and expansion in the last two decades. Yet knowledge generation is not sufficient; its dissemination and internalization by the industry is indispensable for new product development. This paper contributes to providing empirical evidence on the known link between knowledge development and firm growth. In 10 years the cost of electricity produced through CSP has decreased five-fold. This decrease has only been possible due to innovation projects developed through a complex network of research and development (R&D) collaborations and intense investment, both public and (to a greater extent) private. The development and construction of pilot plants and demonstration facilities are shown to be key in maturing innovations for commercialization. This is an example of how the private sector is contributing to the decarbonisation of our energy system, contributing to the objectives of climate change mitigation.

Assessing the Potential to Increase Landscape Complexity in Canadian Prairie Croplands: A Multi-Scale Analysis of Land Use Pattern

Increasing natural vegetation in agricultural landscapes can create habitat for beneficial organisms such as pollinators and the natural enemies of crop pests. Adding perennial vegetation can also support biodiversity conservation and climate change mitigation objectives. However, implementing such changes to agricultural land use across large geographic areas will require a strategic approach. This study examined the amount and distribution of uncultivated areas in Canadian prairie croplands, focusing on Alberta’s agricultural zone (226,543 km2). The aim was to identify locations in this region that have potential for increasing non-crop land cover within fields. This assessment was based on a multi-scale model of landscape complexity that described the distribution of land cover as a function of the distance from field centres. It is based on the assumption that the land cover in the field neighbourhood is an informative index of how much non-crop area might realistically be maintained or restored in the field itself; i.e., because neighbouring lands will reflect the local environmental conditions that support the growth and establishment of non-crop vegetation as well as the likelihood that crop growers will remove areas from production. The model identified variation across the region in land cover distribution, with regions at latitudes between 52oN and 55oN demonstrating the greatest contrasts in the amount of non-crop land between the field and the field neighbourhood scale. These findings suggest that there remains capacity for land use decision-makers to optimize the distribution of non-crop land covers in ways the reduce the differences between these scales (i.e., to increase non-crop covers within fields to better represent the neighbourhood proportions). Modelling also revealed scale-dependent patterns, such as field margins without crops (400 – 500 m from field centres) broadly distributed across the region, and evidence that gradients in moisture and temperature have interacted with land use decisions to shape the proximity of non-crop area to fields.
