The C4R's collective residence was dedicated in part to defining an ecological and adequate way to the principles of the "planetary garden" and the "garden in movement" in the management of the living present on the Terrra project site. Noting the imbalance caused by the invasive presence of black locust trees, it was decided to reduce the number of these trees in the borders of the wooded areas in order to favour a better dynamic of biodiversity. We have also carried out mowing courses, and we have classified the wood cut for later use in the various developments. Following Gilles Clément's advice, the coordination of the workshop days was carried out by Stefan Pop and we also involved the inhabitants of Brezoi who participated by contributing their local knowledge (as well as the use of the draught horse for steep areas).

TERRRA is a trans-local hub for exploring new ways of living, new alliances with nature, better balances between production and consumption. Located in the Carpathian Mountains, in Brezoi, Romania, it offers a space to valorise traditional knowledge, in dialogue with recent technological and environmental advances. TERRRA is also a network of activists acting at the intersection of ecology, architecture, artistic practices, pedagogy and research, through a multitude of practices and projects at different scales. TERRRA will host a branch of the School of Planetary Gardeners, a "disseminated educational project" initiated by Gilles Clément in different parts of the world. Its location will be used as "didactic" material for teaching traditional and contemporary practices of restoring living landscapes (the living). Below, a video dialogue with Gilles Clément on the occasion of a workshop organised in July 2021 in Brezoi. How can we value a unique craft and traditional know-how in an economy that is programming them to disappear? For whom is the learning of these practices intended? Gilles Clément evokes the Romanian artisanal construction practices as a treasure of know-how to be protected, developed and transmitted to future generations. In this sense, the TERRRA hub and the School of Planetary Gardeners will welcome young people who question current practices and are looking for alternative ways of doing. In the longer term, the aim is to change practices through action, and to raise awareness in order to enhance this artisanal know-how and to change the current economic thinking.

The FieldTrip / Worskhop C4R in Bucharest was continued by the roundtable discussion « From local to planetary : changing the way of life » where participated Gilles Clément, Constantin Petcou, Doina Petrescu, Stefan Pop, the Tranzit.ro team and a large public. The introduction by Raluca Voinea noticed the importance of this kind of open discussion as part of the C4R project. Doina Petrescu and Constantin Petcou presented the evolution of a driven-citizens ecological transition strategy (R-Urban) in a global environnemental context which is quickly deteriorating (summaries of the GIEC report were published the previous day). Gilles Clément demonstrated the importance of water for organisms at different scales, as well as the cultural stereotypes that must be overcome by professionals who want to fight against an excessive anthropization of the planet. A discussion with the audience allowed us to explore some ways of thinking grounded in the local context. Many thanks to the Tranzit.ro team for this perfect planning and to all the participants (despite the Covid and the heatwave!) !

A public event: Gilles Clément in dialogue with Civic Movement R-Urban 27 July 2021, 6 pm Casa Filipescu-Cesianu, Calea Victoriei 151, Bucharest “As planetary gardeners, we depend on all the biological diversity that we harness for a living. We must preserve it to ensure a future. What kind of model do we want to develop, to allow both the exploitation of diversity for the benefit of an expanding world population, and the preservation, in quality and quantity terms, of that diversity on which we depend? We must respond to this question as quickly as possible if we are not to succumb to the inevitability of irreversible forces of destruction, but rather to develop in every conceivable field a mental territory of optimism – a garden.” (Gilles Clément, 2021) Gilles Clément is a French gardener, landscape designer, botanist, entomologist and writer. He is the author of several groundbreaking concepts in the framework of landscaping, such as “moving garden” (jardin en mouvement), “planetary garden” (jardin planétaire) and “third landscape” (tiers paysage). For his many landscape projects including the André Citroën Park, the Quai Branly Garden or the Henri-Matisse Park in Lille, he has received the “Grand Prix du paysage“ in 1998. Doina Petrescu and Constantin Petcou (atelier d’architecture autogérée) develop ecological projects carried out with/by citizens, nomadic devices and urban strategies. For their projects (which include EcoBox, Passage 56, R-Urban, Wiki Village Factory, Vision 2030 Seine Saint Denis) they have received a number of international awards including Resilient Building Prize 2018 and European Political Innovation Prize in Ecology 2017. Constantin Petcou and Doina Petrescu represent R-Urban, a civic movement which supports the emergence of alternative models of living, producing and consuming between the urban and the rural. The event in Bucharest is organised by tranzit.ro/ Bucuresti and AAA as part of the project C4R. Jardin Arche de la Défense. Gilles Clément Agrocité Biodiversité, 2014. R-Urban, aaa
