AIPH, in collaboration with the Worshipful Company of Gardeners, proudly presents Green City Briefings 2022/23, sponsored by Expo 2023 Doha, Qatar. This year it is even more global, featuring cities around the world that demonstrate significant progress in including plants and nature in their city’s form and function.
Each one-hour webinar will start with a presentation by an expert describing the principles that explain how urban greening benefits the city, its residents, and nature. The second presentation will be from a city demonstrating how the practice creates transformational change. Facilitated by a fellow leader on the topic there will be discussion structured around submitted questions. This provides experts from around the world the opportunity to showcase and connect knowledge to practice.
Last year the City of London Green City Briefings saw attendees from 50 different countries join AIPH’s series and we hope to see a similar level of inspiration and knowledge sharing this year. The previous eight Green City Briefings webinars presented compelling evidence and examples of the power of ‘living green’ in delivering multiple solutions to city challenges.
In a unique development to the online format, we invite audience members to submit questions and begin discussion on the AIPH Global Green City Forum: A virtual space dedicated to driving transformative change in cities by harnessing the power of plants and nature. The AIPH Global Green City Forum is an online community for all individuals with an interest in learning, sharing, and inspiring a global movement for greener, healthier, and more sustainable cities. Here you can post questions to speakers and join the discussion ahead of each webinar. All the webinar recordings will be available to access on this free platform. AIPH warmly invites you to join the AIPH Global Green City Forum
AIPH also invites you to subscribe to receive the monthly AIPH Global Green City Update direct to your inbox. This monthly mailing comprises the latest news and events, best practice and case studies, policy and green city principles, and research findings from around the world. Subscribing to the AIPH Global Green City Update will ensure that you never miss an announcement regarding the 2022/2023 Green City briefings. Stay up to date with all things Green City by subscribing today!
The Green City Briefing series 2022/23 has explored the many benefits of plants in cities, from their ability to create space for social connection, to their aesthetic and psychological benefits. We have seen how urban gardening and community greening initiatives can create social connections and promote healthy lifestyles, and how integrated urban green initiatives have promoted economic recovery and inclusive growth.
This final briefing highlights the many opportunities to harness the power of plants to create healthier, biodiverse, and more sustainable cities.

The subject of drought tolerance is a central theme of Expo 2023 Doha Qatar.
Dr Mingyu Jiang
Dr Mingyu Jiang’s research explores how different plants co-exist in challenging environments such as those found in urban landscapes. He considers how urban green space features, such as ‘wild’ or naturalistic meadows, develop over the long term to maintain a mix in species for biodiversity and species richness. Mingyu is currently a Teaching Associate in Agriculture, Horticulture And Engineering Sciences at SRUC.
Plants in cities often form part of urban climate change adaptation and mitigation measures. Climate resilient planting provides new ways to develop city planting schemes which are less resource demanding and more sustainable.
This session gives an update on climate resilient planting in London, as well as the latest research trialling the resilience of hedge and shrub plants vital to green infrastructure.
2021’s briefing series explored the project implementing climate resilient planting in the City of London. The City of London is committed to adaptation to climate change with nature at its core.

The June briefing features finalists of the AIPH World Green City Awards 2022: Mashhad, Iran and the Transformative Beltway to Green Belt project.
Responding to urban growth and development is a challenge for cities around the world. Integrating plants and green spaces into urban projects has multiple benefits. This includes reducing air pollution, creating spaces for recreation and improving residential areas. Quality Green Infrastructure increases the value of both residential and business property. A more attractive environment stimulates inward investment and encourages additional visitors to a city.
Mashhad, is located in the northeast of Iran. It has a population of over 3 million and about 20 million pilgrimages and tourists yearly. Construction of 27km highway project began in 1990 in order to facilitate citizens’ access to suburban highways and reduce traffic pressure on the inner-city streets. However, within a few decades the negative effects of this highway project were observed impacting the surrounding environment and the nature of the highlands. In 2018 the transformation of the transport belt began. Different projects such as the development of multi-purpose parks and natural-mountainous parks were designed with the aim of preserving the environment and also developing native vegetation and transforming the “Southern Transport Belt” into a “Green Belt”.

The May briefing features the winner of Category Living Green for Health and Wellbeing category of the AIPH World Green City Awards 2022: Fortaleza, Brazil
Research demonstrates that people are measurably happier when they work and live in green surroundings. This comes from both physical and psychological benefits. Improved health results in lower costs for health-care providers, and benefits the economy through improved productivity and lower absenteeism. This webinar explores how encouraging and engaging with nature and plants in cities results in improved health and wellbeing.
Fortaleza is a city in north-eastern Brazil that, like many other cities, has experienced accelerated urban growth marked by social inequalities. During the Covid-19 pandemic outdoor spaces provided low-risk and strategic places to re-engage with community life. The need for these spaces has continued to today. In the context of Fortaleza, where access to public leisure areas is restricted and unequal, the Urban Micro Parks have become a low-cost and fast implementation way to create places to meet in areas with high population density whilst ensuring people’s health and wellbeing.

The April briefing features the winner of Category Living Green for Biodiversity category of the AIPH World Green City Awards 2022: Bogotá, Colombia
City biodiversity has an increasingly important role to play in global conservation efforts. Cities have a role in providing habitats to support ecological communities for a diverse range of living organisms. Plants provide the backbone for all nature to thrive. This webinar explores how understanding the ecology and encouraging biodiversity in a city benefits both people and nature.
“The greening of Bogotá” is a public policy included in the District Development Plan 2020-2024: “A New Social and Environmental Contract for the Bogotá of the 21st Century”. Its purpose is to improve the quality of the natural, built and regional environment from the perspective of generating well-being conditions for the population and other living beings present in the territory. Agro-ecological urban and peri-urban agriculture takes on special importance as it involves more than 120 plant species in orchards, including fruit trees, shrubs, vines, and even small plants. In 2020, this Urban Agriculture Program gained strength and prominence, resulting in more than 5,000 fortified vegetable gardens.

The March briefing features the winner of the ‘Living green for social cohesion’ category of the AIPH World Green City Awards 2022: Paris, France.
Greener environments encourage people to spend more time in outdoor spaces, improving social interaction and community cohesion which in turn contributes to reduced crime.
This webinar showcased the role of schoolyards in becoming transformative spaces for climate ready cities with cohesive communities. The Oasis Schoolyard’s project, launched in 2018, and, supported by the City of Paris, seeks to transform existing outdoor spaces through renewing and greening all 770 schoolyards by 2050. The project responds simultaneously to multiple urban issues such as thermal conditions, lack of green areas within the city, and the design of appropriate public spaces for children growing up in the city. This includes an active work in community cohesion improvement, which is achieved by providing the local community with free access to the schoolyards on Saturdays. By December 2021, 72 schoolyards had been transformed.
