Title: “An overview of the CAP LTER Program with an emphasis on our social-ecological research on the ecosystem services and bio-cultural services of Urban Ecological Infrastructure”
Abstract: The Central Arizona-Phoenix Long-Term Ecological Research Program has been studying this large metro area since 1997. This urban systems research has always been broadly interdisciplinary and social-ecological, and the ecosystem services that connect “nature in the city” to the city’s inhabitants have long been central to this work. Another central conceptual feature of CAP research is a focus on Urban Ecological Infrastructure (UEI), which is a broad term and idea that encompasses anything in city that supports ecological structure and function; UEI is effectively everything except the actual built environment. In the project presented here, specific types of UEI were chosen for the ecosystem and cultural services—hereafter bio-cultural services—that they provide to nearby residents. Data on resident perceptions and preferences for or against UEI were derived from the Phoenix Area Social Survey. This research addressed the question: What social and environmental features, including proximity to varied UEI, influence perceived bio-cultural services and disservices in PASS neighborhood residents?

Title: “Using Nature to Solve the Global Challenges of Urbanisation”
Abstract: The process of urbanisation has widespread ecological impacts. Many cities face pressing environmental challenges, including elevated temperatures, increased flood risk, and few opportunities for residents to experience nature. Urban ecosystems have the potential to mitigate some of these urban challenges through providing ecosystem services; for example by cooling the air, retaining storm water, and providing recreational spaces for residents. There is increasing interest among planners and designers in better incorporating nature into cities, but we lack an understanding of which nature-based solutions have the greatest potential, and how this varies across climatic and economic contexts in different parts of the world. This talk will present new research that aims to give us a more global, joined-up perspective on the role that nature can play in future cities. It will highlight how new remote sensing and artificial intelligence technologies hold the potential to quantify the role of urban ecosystem services in contributing to human well-being across thousands of cities.
Biography: Dan Richards is a researcher at Manaaki Whenua – Landcare Research, New Zealand. His work looks at how ecosystems provide benefits to people, particularly focusing on cities.

Title: “Understanding the Human-Building-Microbiome Nexus for Sustainable and Healthy Urban Environments”
Abstract: Urban environments are characterized by the concentration of buildings. As humans spend more than 90% of their time in indoors, the built environment is vital for urban sustainability and public wellbeing. Humans, built environments, and microbiomes constitute a system of ecosystems with extensive interactions that impact one another. Understanding the interactions between these systems is essential to develop strategies for effective management of the built environment and its inhabitants to enhance sustainability and public health.

Title: “A Practitioner Perspective on Food System Sustainability’s Complexities in Program and Policy Design“
Abstract: Food systems are complex, interconnected webs of activities, resources, stakeholders, and outputs that collectively produce, process, distribute, and provide food. There is a shared interest in creating food systems that are more sustainable. Sustainable food systems are those that reduce negative environmental impacts, enhance food security, and support the economic vitality of those working in food systems. Designing programs and activities to promote food systems sustainability are nuanced and complex, and often require consideration of local and regional dynamics. These nuances are often not appropriately communicated to consumers. In this session, we will discuss two prominent “sustainable food” messages – to reduce food packaging and to purchase local food – to unpack how these messages can overlook important nuances. Then, we highlight how stakeholders should consider the holistic impact of food system interventions to avoid the trap of overlooking tradeoffs and potential negative consequences.

Title: “Nature-based Solutions for Greywater Reuse in Urban Areas: Benefits, Challenges and Case Studies”
Abstract: The reuse of greywater to meet some of daily water demands in urban areas can bring about number of economic, environmental and community benefits. The efficient treatment of greywater can be achieved by various intensive and extensive methods such as nature-based solutions (green walls, green roofs and treatment wetlands). Apart from water treatment nature-based solutions provide environmental, social and economic benefits, such as biodiversity, reducing heat island and flood risks, resilience, human well-being and aesthetical value. However, the application of nature-based solutions in urban areas is facing some challenges such as: lack of design guidelines, technical issues, unknown risk associated with micropollutants, vagueness in legislation, and poorly defined role within water system and the environment. This presentation will be supplemented with case studies from the Czech Republic (including the campus of the Czech University of Life Sciences Prague) and foreign collaborators.

Abstract: In the Parana River Delta (1.78 Million hectares, Argentina), an inter-institutional Participatory Land Use Planning Process (PLUPP) is being built with both, scientific and empiric farmer knowledge support. This process seeks to find consistent management answers to a changing world. It occurs in one of the principal wetlands Systems of South America that is; also, a key river transport network for three countries (Argentina, Bolivia, and Paraguay). It is, besides, the principal source of freshwater of an urban riverine Region that holds 24 million inhabitants. To safeguard the continuity of the wetlands key ecosystem services production processes (involving e.g.: flooding mitigation, biodiversity conservation, water pollution control, islands silvopastoral systems), there are ongoing different research programs and social networks that are working articulated in PLUPP. These programs and networks are looking forward to alleviating negative effects that arise from current land use and cover change (LUCC) processes across the Region.

Winifred Curran, Ph.D.
Professor, Department of Geography, DePaul University – Chicago, Illinois
Country: United States of America
Title: “A “Just Green Enough” Approach: Urban greening without displacement”
Abstract: Too often urban greening projects are tied to an outward-looking, postindustrial urban growth agenda. This focus ignores interventions which are less visible, smaller scale, and serve a working-class population in still-industrial areas of the city. In this talk, I offer examples of small-scale interventions undertaken by the Newtown Creek Alliance to accomplish demonstrable environmental improvements along the heavily polluted industrial waterway of Newtown Creek in New York City. Though largely invisible within the larger conversation on greening and urban development, these interventions have the potential for substantive environmental improvement that benefits existing long-term residents and users rather than being a tool to attract new residents and luxury development. This example serves as an attempt to diversify the “best practice” case studies that will inform future urban greening projects.
Biography: Winifred Curran is a Professor of Geography at DePaul University. Her work focuses on the effects of gentrification on the urban landscape. She is the author if Gender and Gentrification (Routledge 2018) and co-editor, with Trina Hamilton, of Just Green Enough: Urban Development and Environmental Gentrification.

Assistant Professor, Department of Civil and Environmental Engineering and National Center of Supercomputing Applications, University of Illinois at Urbana – Champaign, Illinois
Country: United States of America
Title: “Global Multi-model Projections of Local Urban Climates”
Abstract: Cities are where major human-perceived climate change impacts occur. Many globally recognized climate threats such as heat stress, water scarcity, air pollution, energy shortage, extreme rainfall, and flooding are either rooted from or exacerbated by the unique urban climatology combined with the concentrated population and infrastructure. These hazardous risks are projected to be further worsen due to climate change coupled with rapid urbanization. Effective urban planning and adaptation for climate-driven risks relies on robust climate modeling that are specific to built landscapes with quantitative characterization of uncertainties. Such projections, however, are largely absent because of a near-universal lack of urban representation in global-scale Earth system models. In this seminar, I will present a newly developed urban climate emulator framework that combines process-based Earth system modeling and data-driven Physics-Guided Machine Learning (PGML), and its applications on understanding the local urban climate change, variability, and uncertainty, and climate impacts to built environments at the global scale.
Biography: Lei Zhao is currently an assistant professor in the Department of Civil and Environmental Engineering and assistant professor affiliated with the National Center of Supercomputing Applications at the University of Illinois at Urbana-Champaign.

Title: “Urban Warming Advances Spring Phenology but Reduces the Response of Phenology to Temperature in the Conterminous United States”
Abstract: We investigated the changes in satellite-derived start of season (SOS) and the covariation between SOS and temperature (RT) in 85 large US cities between 2001 and 2014. We found 1) SOS came significantly earlier in 74 cities and RT was significantly weaker in 43 cities when compared with surrounding rural areas 2) decreased RT mainly occurred in cities in relatively cold regions with annual mean temperature <17.3 °C; and 3) urban−rural magnitude difference in both SOS and RT was primarily correlated with the intensity of urban heat island. Model simulations further suggested more and faster heat accumulation contributed to earlier SOS, while a decrease in required chilling led to a decline in RT magnitude in urban areas. These findings provide observational evidence of a reduced covariation between temperature and SOS in major US cities, implying the response of spring phenology to warming in nonurban environments may decline in the future.

Title: “Lessons and Opportunities for integrated Engineering and Earth Systems Science as Solutions to Water in a Changing Climate”
Abstract: Climate change is happening. Climate change is no longer a hypothesis. It is a fact. The solutions are expected to be developed. To develop a framework for a systems approach to studying the Earth and to identify facilities, infrastructure, coordinating mechanisms, computing, and workforce development needed to support future work, it bridges the gap between engineering and earth systems science to share successful strategies and discuss challenges. Making further progress will require lowering institutional and cultural barriers to engagement across traditional scientific disciplines and advancing transdisciplinary efforts that a foster greater understanding of the interdependencies among the Earth system components. There are examples, Practicable predictions of water quality and quantity, as well as floods and droughts, require data-driven models and smart sensing systems. Exascale computing, edge computing, and 5G offer the promise to accelerate scientific discovery and revolutionize engineering approaches through data-driven and physics-constrained to build a next-generation civil infrastructure

Abstract: Community and stakeholder engagement is essential to science at the nexus of food, energy, and water systems (FEWS). Local knowledge contextualizes complex interactions among food, energy, and water systems and helps identify more effective solutions. Based on a review and meta-synthesis of a broad range of existing models, frameworks, and toolkits for community and stakeholder engagement, a framework is proposed for best practices in community and stakeholder engagement in FEWS. The framework includes situational awareness of the FEWS place or problem, creation of a suitable culture for engagement, focus on power-sharing in the engagement process, co-ownership, co-generation of knowledge and outcomes, the technical process of integration, monitoring processes of reflective and reflexive experiences, and formative evaluation. The framework is considered a scaffold to support the development and application of best practices in community and stakeholder engagement in ways that are essential for sound FEWS science and sustainable management of ecosystems for human use.

Andrea Ludwig, Ph.D.
Associate Professor, Biosystems Engineering and Soil Science, University of Tennessee – Knoxville, Tennessee
Country: United States of America
Title: “Natural Drainage Systems to Restore Ecosystem Services in Residential Landscapes”
Abstract: The urban water cycle is plagued with imbalances that can act as stressors to the ecosystem. Managing water quantity and quality in urban and urbanizing watersheds through natural drainage systems may lessen that impact and help restore ecosystem services that have been lost. Natural drainage systems are an alternative to grey infrastructure for managing stormwater runoff through redesign of residential areas to take advantage of the natural capacity of plants, soil, and the landscape to clean runoff and manage flows. Rain gardens, bioswales, created wetlands, and permeable pavements are all components that may be used in a natural drainage system. Innovative design is needed that addresses unique ecoregion conditions as well as across a range of built environment applications. Just as important are the human elements of acceptance by residents and maintenance and management by those responsible for their long-term effectiveness. This talk will explore the physical, ecological, and human dimensions of natural drainage systems and showcase some case studies in East Tennessee, USA.
