The ‘Living Green, Liveable Cities’ Research Symposium took place 4-5th February 2024 in Doha, Qatar, alongside Expo 2023 Doha Qatar.
The Research Symposium accompanied the special Cities & Health journal issue, also titled ‘Living Green, Liveable Cities’. This special issue was instigated by AIPH and Expo 2023 Doha Qatar to investigate the science and practice supporting the concept showcased by the Expo of creating liveable and healthy urban environments through city greening.
Contributing authors to the special issue gave presentations on their research at the Symposium, focussing on three themes:

Judith (1979) studied Garden and Landscape Design in Velp (2001) and graduated from the Academy of Architecture in Amsterdam (2015) as a landscape architect. In her graduation project on Huzhou (China), she combined her travel experiences with keen interest in cultural landscapes. Huzhou has beautiful historical water and green structures, which form the potential areas for the city’s future expansion. She proposed an alternative green structure design which would preserve the city’s identity. The green zones will be a living and breathing element in the city and serve to reduce problems such as poor air quality, water pollution and heat stress.
In addition to being the company’s landscape designer, in 2019 Judith became the director and owner of Niek Roozen Landscape. Judith excels in creating strong, detailed concept designs in which positive existing landscape qualities are preserved and serve as the design foundation.
Judith has a considerable amount of experience in landscape design projects in the Netherlands and in China. In recent years, rapid development in China resulted in a high demand for large scale projects in rural regions and tourism-oriented designs on the fringes of larger cities. In the Netherlands we worked on themes like greening new city parts, but also revitalising and intensifying existing neighbourhoods is a way of making cities greener and healthier. The design team is knowledgeable and committed in creating realistic design plans where nature, culture and recreation are harmonized and form a synergistic relationship.
The urban environment contributes to important issues such as flooding, drought, heat stress, lack of greenspace, biodiversity reduction, air pollution, and climate change. One of the core philosophies of the company is the green city principles, in which we believe that the right type of greenery in the right place can contribute significantly to improving the quality of urban environments. We were involved in numerous designs of various scale both in The Netherlands and abroad, where the appropriate application of the green city principles became important added value elements for the projects.
Connecting research, policy and practice, Dr Souter-Brown’s holistic systems thinking led Taylor Francis to name her a ‘global thought leader’ UN Sustainable Development Goals #3 Good health and wellbeing, #11 Sustainable Cities and Communities, #13 Climate Action and #15 Life on Land. Her multidisciplinary approach bridges landscape architecture, public health and ecology. She is special envoy from the International Federation of Landscape Architects to the International Society of Urban Health.
Souter-Brown’s research and practice explore human-nature interaction as it impacts stress and hence incidence of non-communicable disease. Effects of the qualities of the built and natural environment on physical activity, diet, wellbeing, feature across her work. Unafraid to question the status quo, she uses quantitative methods to inform her work, balanced by the qualitative ‘how things feel’.
Interested in health promotion, mental health and sustainable development, Dr Souter-Brown integrates innate wisdom, indigenous knowledge, and modern-day mixed methods research. Working remotely and in-person, her international award-winning salutogenic design practices reference theories of place, attachment, stress reduction, attention restoration and biophilia. Author of the international text Landscape and Urban Design for Health and Wellbeing, she researches, writes, is an invited speaker, advises and teaches internationally. Gayle is based between London, England, and her farm in rural Canterbury, New Zealand.
Dr. Aura-Luciana Istrate is an Assistant Professor in the School of Architecture, Planning, and Environmental Policy at University College Dublin, Ireland. She is the Primary Coordinator of a Doctoral Network (C-NEWTRAL) under a Marie-Sklodowska-Curie-Actions scheme, aiming to advance new approaches for integrated planning of climate-neutral cities through citizen engagement and city governance decision-making support. She is co-leading another Horizon Europe project (REALLOCATE) focusing on rethinking the design of streets and public spaces to leverage modal shifts towards climate-friendly active mobility in 10 European Cities. Her main research interests concern public spaces, active mobility, integrating nature-based solutions in cities, and overall improving urban liveability.
