On July 8th, 2026, Connective Cities hold an online Insight Session to explore ways, by which urban forests can be cultivated under difficult climate conditions. Attempts to do so are notoriously difficult in dry regions with high temperatures and low precipitation, where the usage of scarce water resources has to be distributed between (urban) populations, local businesses, agriculture and industry. Planting and watering urban trees is regularly considered secondary under such circumstances, leading to unsuccessful attempts of urban afforestation due to a lack of financial support and maintenance work. The Insight Session was joined by 34 participants from 13 countries, representing a broad range of municipalities from Africa and the Middle East.
Over the past decades, the Miyawaki-method of planting tiny forests has become an outstanding success story around the globe. In this technique developed by Japanese botanist Akira Miyawaki, a small dense forest is made from native trees and plants. The specifically dense way of planting a miscellany of indigenous plants accelerate the growth of flora and fauna, so that after around five years, micro forests may already be entirely self-sustaining. The forests improve air quality, reduce heat and bring back lost biodiversity, thereby stabilizing ecosystems and countering the environmental degradation as a result of the climate crisis. A videographic overview of the Miyawaki-Method can be found here.
Stefan Scharfe, speaking on behalf of Miya-Forest, a forest-planting/educating/researching NGO based in Eberswalde, Germany explained the success of the Miyawaki method through the instance, that planting trees is usually broadly accepted among a range of actors such as urban populations, housing providers and local administrations. However, the participatory approach of planting urban micro forests must be facilitated through a small group of core actors who take ownership of the project. Especially a thorough soil study can significantly increase the chances of the micro forests to become self-sustainable after an initial, intense phase of watering and caring.
Coming from the highly urbanized and biodiversically degraded context of Amman, Jordan’s Capital, Deema Assaf from the ecological research studio TAYYŪN joined the Insight Session as a second speaker, providing the participants with valuable hands-on insights from the MENA region. Mrs. Assaf elaborated on the tedious work with paleobotanists to collect evidence of indigenous species from the region, proven evolutionary resilient towards the local climate conditions. The seeds of these plants known to the soil form the base for a multi-layered ecosystem featuring canopy, sub-canopy, shrubs and ground cover tiers. Over the course of its growth, the micro forest attracts insects, mushrooms and birds. Also edible plants may be included, turning micro forests into sites of (urban) gardening.
In result, the Insight Session provided the participants with new inspiration for their own project development within the scope of the currently running Connective Cities learning processes on ‘Nature at the Heart of Municipal Resilience’ and ‘Green Corridors in the City and its Surroundings’. The potential of the Miyawaki Method to produce fast and self-reinforcing benefits through various ecosystem services and according to the local circumstances makes urban micro forests a tangible and fitting intervention in the current situation of intensifying climate crisis. However, forestry-related preparation – i.e. soil data and seedlings –, as well as institutional backing, secured funding and maintenance of the planting project are key elements for micro forests to thrive.
Connective Cities provides the network for future engagement on the topic and looks forward to share expertise among urban practitioners
