Dr. Marcus Collier

Associate Professor (Botany)

I am fascinated by the human-nature interface and I specialise in social-ecological systems thinking. My many research interests include land use and land-use change, resilience thinking and societal transitioning, collaborative management and planning, urban and rural governance. Notable examples of my research include the contentious policy issues of biomass/bioenergy land-use policies and implications, afforestation policies and acidification processes, field boundaries and agri-environmental change, resource use and after-use policies, rewilding, GM crops and biodiversity, marine and coastal governance, (cultural) ecosystem services, and well-being. In recent years I have published extensively on contested issues such as novel ecosystems and nature-based solutions. As an environmental consultant, prior to entering academia, I worked with volunteers and non-governmental agencies to co-create and implement environmental projects through adaptive collaborative processes. I often draw on my practical experience in the co-creation and co-design of environmental projects to shape empirical research methodologies for use in testing new mechanisms for collecting data. This co-production of knowledge (transdisciplinarity) is essential for achieving the proposed Sustainable Development Goals. My PhD research was an exploration of collaborative governance policies and future land use in severely damaged landscapes. For this, I examined (conflicting) stakeholder rationalities and power asymmetries.

To these ends, the paper analyses how policy officers manifest capacities for co-production in three European cities " Genk (Belgium), Glasgow (United Kingdom), and Poznan " (Poland) " while experimenting with co-production to develop and scale nature- based solutions. Co-production capacities include conditions and activities to (1) create space for co-production, (2) safeguard inclusive and legitimate co-production, and (3) link co-production processes and results to contexts. The results demonstrate how policy officers in the three cities have mobilised and created resources, skills, institutional support, and partnerships to implement diverse processes to co-produce nature-based solutions. While these conditions mark starting changes in urban governance, engaging with and embedding co-production causes tensions between the dynamic and diffuse nature of co-production and existing formal governance settings and processes. Lessons for strengthening the capacities to embed co-production as a collaborative governance practice in nature-based solutions planning, delivery, and stewardship are: (1) embedding a tailor-made approach for inclusive co-production to meaningfully engage diverse actors in place-based settings, (2) embedding open-ended co-production with long-term benefits, and (3) embedding new relations and roles to sustain co- production.], Journal Article, PUBLISHED  TARA - Full Text  DOI  URL
Cooper, C.; Cunningham, N.; Bracken, L.J.; Collier, M.J., Distribution of Nature-based Solutions in cities across Europe, Land Use Policy, 141, 2024, p107160 , Notes: [Nature-based Solutions (NBS) is a conceptual framework that seeks to use properties of nature to co-produce ecosystem services to build climate change resilience and improve quality of life by mitigating the relationship between health inequality and socio-economic adversity. This study investigates how the distribution of these forms of urban nature relate to trends in demographic change and social and economic indicators that influence material aspects of quality of life (QoL) in cities. Using macro-scale spatial mapping and descriptive pattern identification, we examine the relationship of distribution trends in the key characteristics of NBS across European cities and social and material factors that influence QoL. Our findings suggest that less than 6% of NBS aim to address poverty or deprivation and fewer than 25% relate to housing or neighbourhood regeneration. We argue inattention to the complex intersectional relationship of socio-economic disparities, historical structural conditions, and the impact of changes to the structural policy on economic convergence across regions leading to the concept being used to address green-growth imperatives in Western Europe rather than mitigate inequalities across eastern and parts of Southern Europe. Failure to address these considerations in the design and deployment of NBS could lead to cities reinforcing or even worsening inequalities within deprived communities, particularly in these areas.], Journal Article, PUBLISHED  TARA - Full Text  DOI  URL

Grey, T.; Xidous, D.; O'Neill, D.; Collier, M.J., Growing Older Urbanism: exploring the nexus between ageing, the built environment, and urban ecosystems, Urban Transformations, 5, 2023, p8 , Notes: [Background Some of the main urban issues we currently face include ageing populations, the impact of the built environment, and the treatment of urban ecosystems. Yet the dynamic relationships and synergies between these issues, and how they are influenced by urban growth and evolution, receive little attention. Research focus We explore the nexus between people, the urban built environment, and ecosystems as they grow, age, change, and evolve and propose an integrated approach to examine the relationships, synergies, and challenges that may emerge over time within urban neighbourhoods. We argue that this should draw on the lived-experience and wisdom of older people as part of an intergenerational approach underpinned by local, traditional, and ecological knowledge. We propose Growing Older Urbanism as an ecological, co-evolutionary, and complex-adaptive-systems-based framework to explore the nexus between ageing, the built environment, and urban ecosystems and to reveal the synergies and antagonisms that might exist between these three elements. This framework is designed to be used for various types of urban neighbourhoods, and by a diverse range of stakeholders. As part of this approach, we provide a preliminary visual canvas to illustrate how the framework might be used within a selected neighbourhood over an agreed timespan. Conclusion This paper presents some early thinking around the Growing Older Urbanism concept, while also outlining questions and a proposed transdisciplinary research programme to further develop the framework. We argue that understanding the relationship between ageing and the co-evolution of people, place, and ecosystems may teach us about our past, present, and future, and help us grow towards inclusive and sustainable communities.], Journal Article, PUBLISHED  DOI  URL

These urban novel ecosystems or informal wild spaces are often perceived as in-between or overlooked, calling into question their value and social-ecological role, while also creating tensions amongst different groups and stakeholders who share different visions for their use and management. Within these tensions, issues of justice and equity can be more pronounced and surface historic legacies of environmental contamination, inequitable development, and extraction. Despite this, very little is known about the social-ecological role informal wild spaces play in urban areas, and how best to interrogate and understand the equity and justice dimensions they elicit. To fill this gap in knowledge, this paper critically examines the literature on urban novel ecosystems in relation to justice, with a particular interest in multispecies justice. Through this analysis, gaps in the literature are exposed, while also arguing the informality, neglect and contestation of wild urban spaces provides opportunities to explore issues of access, benefits and harms, particularly in light of global climate and ecological crises. A systematic approach is utilized to search the literature, identifying 45 papers which are thematically analyzed under a justice lens. The study identifies three themes that thread throughout the literature: distributional injustices relate to perceptions and attitudes, which give rise or arise from injustices; the regeneration discourse focuses on a 'new nature', which is based on social-ecological displacement and devaluation; and the potential of urban wild spaces to generate new multispecies sensibilities. The paper concludes by discussing trends, gaps, and emerging discourses, and proposing a multispecies justice approach for urban planning through the learnings and engagement with urban wild, novel ecosystems.], Journal Article, PUBLISHED  TARA - Full Text  DOI  URL

Furthermore, taking nature-based solutions to the next level, and scaling them out to all urban contexts to achieve a greater impact, is proving to be slow and often conflicts with other transitioning initiatives such as energy generation, mobility and transport initiatives, and infilling to combat sprawl. So, the task is neither easy nor straightforward; there are many barriers to this novel transition, especially when it comes to collaborative approaches to implementing nature-based solutions with diverse urban communities and within city authorities themselves. This paper reports on a new process that is systematically co-produced and captured as a framework for planning nature-based solutions that emerged during the Connecting Nature project. The Connecting Nature Framework is a three-stage, iterative process that involves seven key activity areas for mainstreaming nature-based solutions: technical solutions, governance, financing and business models, nature-based enterprises, co-production, reflexive monitoring, and impact assessment. The tested and applied framework is designed to address and overcome barriers to the implementation of nature-based solutions in cities via a co-created, iterative, and reflective approach. The planning process guided by the proposed framework has already yielded promising results with some of the cities of the project, though further usage and its adoption by other cities is needed to explore its potential in different contexts especially in the Global South. The paper concludes with suggestions on how this may be realised.], Journal Article, PUBLISHED  TARA - Full Text  DOI  URL

To this end, it reports how policy officers in ten European cities have started to mainstream NBS by interacting with and changing incumbent governance arrangements when experimenting with novel governance processes and mechanisms to plan, deliver, and steward NBS. Based on these activities of the policy officers, the analysis identifies three strategies, associated stepping stones and changes in governance conditions, to mainstream NBS in governance capacities: institutionalising (a) a systems" approach to link NBS to policies, regulations, and departments across goals and sectors, (b) inclusive collaborations for localised and inclusive interventions, and (c) reflexivity and learning about how NBS interact with the (institutional, ecological, social, etc.) contexts and create impacts. The strategies illustrate institutional entrepreneurship in interacting with incumbent governance contexts, and how starting from NBS as a type of systemic innovation can promote broader shifts in urban governance arrangements.], Journal Article, PUBLISHED  TARA - Full Text  DOI  URL

Measure 5 deals with field boundaries and advises farmers that the one way to rejuvenate an overgrown "leggy" hedgerow (Option 5A) is to use a 'traditional' form of management known as hedgelaying. Hedgelaying is suggested as a method for rejuvenating a hedgerow whilst also making them stockproof. Among countryside managers a commonly held belief is that hedgelaying is an excellent way to conserve and augment hedgerow biodiversity and hence the reason why the REPS suggests it. This is because the woody element of the hedgerow is rejuvenated, the existing (genetic) stock is maintained, species variety is conserved and the overall life of the hedge is prolonged. However, there are very few data relevant to Ireland to support these claims and much of the ecological values assigned to hedgerows in Ireland are based on studies carried out in other juristictions. This six year study was carried out subsequent to a series of hedgelaying training courses in 1998 and it shows that when a hedgerow is laid, bird species rapidly colonise the hedge and that the number of nests declines annually. This is shown by the number of nests present annually and so may serve as an indicator of the value of hedgelaying for birds. Comparison is made with the only other study carried out in these islands which was nearly 30 years ago in England.], Conference Paper, PUBLISHED

Collier, M.J., An ecological evaluation of field boundary stone walls in Ireland, Environ 2005: 15th Irish Environmental Researchers' Colloquium, Sligo Institute of Technology, 28-30 January, 2005, pp1 , Notes: [The ecological values of field boundaries in Ireland are poorly understood and many of the currently accepted values are based on extrapolated data from detailed boundary research in the UK, France and elsewhere. Though these locations have similar ecological characteristics as Ireland, and possibly a greater post-glacial biodiversity, it ought not to be concluded that Irish field boundaries have identical or even similar functions. Much of the data in Ireland relate to field boundary landscape characteristics and/or mis-management as opposed to ecological research based on field data. The limited research that has been carried out in the Irish Republic is on hedgerows and field margins. Some research has yielded data in relation to specific taxonomic groups yet it may be claimed that though much emphasis has been placed on the value of hedgerows there are little data to support this. The data that are available for stone wall boundaries are even less developed than those for hedgerow boundaries. This could be because a stone wall might not viewed as a 'living' habitat as hedgerows often are. Research on the ecology of stone walls globally is also surprisingly poor with much of the data relating to secondary (inferred) sources (Dover et al. 2000). Only two publications are exclusively concerned with stone wall ecology. Segal (1969) and later Darlington (1981) have produced seminal volumes on the ecology of urban walls and walls of old buildings. Both books refer in passing to field boundary walls but do not explore this area. In general, ecological references are few and most are unsubstantiated and even hearsay. In a trawl of the available literature it was found that no publications dealing exclusively with the ecological characteristics of field boundary stone walls, such as those that may be found throughout the Irish countryside, existed. This is quite surprising as boundary stone walls are recognised as a specialised habitat (Fossitt 2000) and are generally assumed to be of value to wildlife - in exposed areas particularly.], Poster, PUBLISHED

Collier, M.J., Proposal for the description and classification of wallrows in the Irish Landscape, ENVIRON 2004: 14th Irish Environmental Researchers' Colloquium, University of Limerick, Ireland, 30thJanuary-1st Febr, 2004, Notes: [Abstract: Field boundaries are a key feature of the Irish landscape and the most common of these are earthbanks, hedgerows, stone walls and fences. While carrying out a trial field boundary assessment survey form for the Field Boundary Evaluation and Grading System (Tearmann, 2003 in press), which focussed exclusively on hedgerows and dry stone walls, it was discovered that there is an undescribed classification of field boundary in Ireland. In areas where stone wall field boundaries are prevalent in the landscape it was noted that, in nearly every location, there has been some spontaneous scrub regeneration in close proximity to the wall. This regeneration is usually linear in nature, paralleling the wall itself, and often contains woody shrubs species commonly found in scrubland or in hedgerows. It is proposed that these features receive a separate classification, wallrow, and that research be undertaken into establishing their morphology, the factors contributing to their formation and their ecological role in the landscape. The purpose of this poster is to stimulate discussion on the topic, seek more information on these landscape features and to establish an opinion on whether wallrows may be ecologically important. A case in favour of separate classification is set out.], Poster, PUBLISHED

M.J.; McCabe, O. & Farrell, E.P., PNtrap Project: Using trees and woody shrubs to intercept excess nutrient in farm and forestry runoff, 7th IWA International Conference Diffuse Pollution and Basin Management, UCD, Dublin and Johnstown, Co. Wexford, 17th-22nd August, 2003, pp1 , Notes: [Water protection has long been a cornerstone of EU environmental policy. It is the sector with the most comprehensive coverage in EU environmental regulations (Kallis & Butler 2001). Water catchment nutrient management is poorly developed in Ireland and runoff nutrient entering watercourses is increasing (Tunney et al 2001). This has a serious and detrimental effect on water quality as well as ecological processes. In European countries such as the Netherlands, France, Sweden and Italy, national and local governments have implemented substantial programmes aimed at combating excessive nutrient loss to watercourses from agricultural, silvicultural and waste treatment activities. It has been demonstrated that many trees have the ability to intercept and absorb large volumes of nutrients (Hefting & de Klein 1998). Buffer plantations of, often, willow (Salix spp.) and other species may be established in order to effectively and efficiently intercept surface runoff of nitrate (N) and phosphate (P). In addition, such buffer plantations could themselves produce an annual crop requiring little management and low-priced technology to harvest. Yet, the science behind the application has not been established in Ireland. The PNtrap project is currently under development in the Forest Ecosystem Research Group in the Department of Environmental Resource Management, UCD. The aim of this innovative project is to investigate the nutrient interception and absorption properties (N and P) of broadleaved trees, especially native species and varieties, and the beneficial effect that this may have for watercourse management in relation to farm and forestry runoff. The objective is to develop trial plots and test scenarios in order to identify the optimum tree and woody shrub species. The PNtrap project will commence in late 2003 and will run for a minimum of three years. Though the primary aim of the project is to establish a scientific basis for the utilisation of trees and woody shrubs to intercept nutrient entering watercourses, it is hoped that this will reveal if woody buffer zones are capable of protecting water catchments from N and P enrichment in Ireland.], Poster, PUBLISHED

My research investigates the complex and dynamic interface between ecosystems and a transitioning society, which I feel is highly suited to the E3 arena in TCD. My research focuses on the arenas of natural capital and urban resilience, where I investigate perceptions, values, and relationships between landscape characterises, land-use change, governance, and societal expectations. In support of the E3 project, there are three thematic areas of inquiry that have run throughout my career as a researcher, evaluator, and research manager that have relevance. These are: Environmental sciences My research here has focused on complex social-ecological systems, with particular interest in: 1. novel ecosystems and their societal implications; 2. socio-cultural ecosystem services and valuing nature; 3. social-ecological resilience in anthropogenic landscapes; 4. environmental and landscape management; 5. cultural ecosystem services and land-use change; and 6. restoration/rehabilitation ecology. Sustainability science My research in the sustainability science arena looks at: 1. transitioning to sustainability through co-creation for normative behaviour change; 2. sustainability science and transdisciplinarity (theory and practice); 3. social capital networks and their intersection with natural capital; 4. green infrastructure, multifunctionality, and nature-based solutions; 5. collaborative governance and the co-production of knowledge; and 6. sustainable urbanisation in a globalised context. Environmental geography My research here seeks to advance current theory and debates, exploring transdisciplinary approaches to crowd-sourced data gathering and analysis. This involves co-creation, co-design, and co-production of knowledge, and disseminating results to and within communities of interest. For example: 1. the Anthropocene and human/nature inter-relationships; 2. power asymmetries, conflict, and governance in the urban; environmental arena; 3. collaborative processes (citizen-led) and innovation; 4. urban-rural geographies (from production to post-production to multi-functionality); 5. complementary methodological research (qualitative and quantitative). There are several avenues in transdisciplinary research that I am currently pursuing. I have identified these as key areas of potential influence in global discourses as well as being aligned with key areas of emerging funding: 1. nature-based solutions via the co-production of knowledge, using sustainability science and crowdsourced data for communicating and transforming normative behaviour; 2. climate adaptation and the role of the 'futurescapes'; 3. emerging discourses on the utility of green infrastructure and ecosystem services; 4. exploring and quantifying novel and emerging ecosystems: the human/ecological interface in abandoned urban areas; and 5. pathways towards a science of transition: mapping crowdsourced socio-cultural values.
