Since the beginning of February, a new exhibition at the Museum of Applied Arts in Cologne(MAKK) has been all about trees. The exhibition “Between the trees” highlights the relevance of urban trees in various ways. After all, they perform key cooling and air purification functions for the urban environment. At the same time, they serve to regulate rainwater. Last but not least, numerous studies have shown the impact of a green environment on the mental and psychological health of city dwellers. In addition to all these essential aspects of life, the tree also serves as an inspiration for people. The exhibition also highlights the tree as a material and spiritual resource for design and art.

The MAKK will showcase this range through international projects that deal with the tree in an urban context. Representatives from the fields of conceptual design, industrial design, arts and crafts and fine arts are taking part in the exhibition. Thanks to the diversity of approaches, “Between the Trees” paints a multi-layered picture of the tree as an object. The material, functional and aesthetic components are to be presented to visitors in equal measure. For example, the artists place the significance for climate change alongside an examination of the availability and use of the raw material. Or, on the one hand, address issues of urban planning, while at the same time fundamentally addressing the domestication of nature. Through the approachable object of the tree as a representative of the entire wealth of nature, abstract concepts become more tangible. And visitors can approach topics such as sustainability or the importance of natural habitats in an emotional way.

“Between the trees” is divided into three sections. The biological-climatic level, entitled “Rethinking the tree”, offers an overview of the essential functions that trees perform for the earth’s ecosystem. Designers at the MAKK are inspired by these abilities and show inventions that are based, for example, on the careful use of resources. In addition to the biological-functional properties, this section of the exhibition also shows the challenges posed by the urban environment and climate change.

The material level, subtitled “The tree used in a new way”, shows the variety of materials that trees provide for humans. In addition to wood, these include cellulose, lignin, bark and leaves. Furthermore, not all wood is the same. Weight, flexibility and hardness vary depending on the tree. And that’s not all. As a living material, it is constantly changing. The impressive diversity is offset by hard facts. Although renewable, wood as a raw material is also limited. The exhibition pays particular attention to the scarcity of resources and at the same time shows ways of using them sparingly in the future.

The second exhibition area, the cultural level, is subtitled “The tree reinterpreted”. This shows an interesting change of perspective. It is well known what positive effects trees have on the urban environment. However, little attention is paid to how trees fare under the influence of the urban environment. Exhaust fumes, sealed soils and water shortages are challenges that urban trees have to contend with on a daily basis. At the MAKK, the artists ask themselves what a respectful coexistence could look like. For example, design approaches will be presented from the perspective of trees. In a vision of the future, the tree could be perceived as a living subject and not just as part of street furniture.

The exhibition was created in collaboration between the MAKK and the Ökorausch Think Tank e.V. In addition to the exhibition, public events will accompany the program. Fruit trees will also be donated to private individuals with the support of the German Forest Protection Association. In the spirit of the Edible City of Cologne campaign, the exhibition is thus growing beyond the boundaries of the museum and will nourish local residents in the future. “Between the trees” can be seen in Cologne until April 16 of this year.

The exhibition “Garden Futures” can be seen at the Vitra Design Museum until October 2023. It shows the importance and design of the garden through the ages in a variety of ways. And its role for the future. Find out more here: Garden Futures.

“Daily use is the best protection”

Philipp Speiser has been restoring in Egypt for many years. He is an honorary professor at the TU Berlin and director of the project “The Fatimid Cemetery in Aswan”, which was successfully completed in 2014 and in which a sector of the necropolis was documented and restored.

Archaeological sites are being looted in Egypt – what are the current conditions for restoration in the country?

I can only speak for our project. I think restoration and looting have little to do with each other, except that places that are being worked on are better supervised during the work on site. The conditions for restoration are the same as before the revolution.

You have been restoring in Egypt since the 1980s. What has changed for you and your work since the revolution in spring 2011?

Nothing has changed for us since the revolution, as the German Archaeological Institute (DAI) still maintains excellent contacts with the Egyptian antiquities administration. We have the same Egyptian partners and local staff as before the revolution.

To what extent was the Fatimid Cemetery the target of looting?

On the one hand, the cemetery is naturally used regularly and is considered a sacred place that is respected as such. There is therefore constant supervision by the users, and its daily use is the best protection.

Secondly, there are no antiquities or finds that can be sold for profit.

In your opinion, how can the archaeological sites in Egypt be protected from looters?

Only through an appropriate presence of guards and wardens and a greater awareness among the population of the archaeological heritage and its importance. For this reason, the DAI has launched several educational programs for cultural preservation in Egypt. It is to be hoped that economic stabilization and the growth of tourism, particularly in the Nile Valley, and the resulting financial improvement will reduce looting.

Spatial Planning Matters! – Book review

Scientists at ETH Zurich have published an anthology on the planning process. It contains both practical examples and theoretical essays. And is a must for students.

Planning is mysterious. With increasing complexity, the process of a project becomes more decisive than the physical intervention. Whose voices are drowned out, what role do planners play in this process? Scientists at ETH Zurich organized a series of seminars on these questions with international scientists and practitioners from the planning world. The 232-page book documents the research results.

How to avoid planning errors

The publication has an exemplary structure and consists of two main parts: “Inspiring stories” and “Fundamental topics”. The first part presents seven completed and nine ongoing projects that demonstrate a variety of challenges and approaches to planning practice in Europe and the USA.

The essays on the “fundamental themes” discuss issues and innovative strategies. They should be considered in the various phases of the planning process. For example, the essay “Planning approaches or nothing comes from nothing” mentions that problem analysis at the beginning of planning is crucial and should not be ignored. The lack of a broad discussion of the problems was, for example, one reason for planning errors in the Stuttgart 21 project.

Focus on social aspects

The structure of the book fulfills its purpose of bridging the gap between practice and theory and reaching a broad audience outside specialist circles. The content of the publication is innovative and scientifically sound. It has a clear and concise structure, cross-references between examples and theory, an informative but restrained layout. The clear structure helps people with different backgrounds to better understand the planning process. Professionals can better understand innovative theories and the connection between theory and practice thanks to the example-oriented structure, the notes and the glossary.

Non-experts can rely on the detailed narratives and rich diagrams in the example chapters to understand key planning processes. However, the book’s perspective on planning focuses on social aspects. It leaves open how nature can be included as an important stakeholder in planning and how the process should change to adapt to climate challenges, for example.

A must-read for planning students

Furthermore, the examples focus on Europe, with a brief mention of the United States. Some non-European planning projects would be quite interesting for research and discussion. The European examples are sufficient for new insights, but exploring more projects in different contexts and developing theories, regardless of success or failure, would make the planning mechanism and theory more robust and universal.

This book is not a substitute for a comprehensive planning textbook, but it is innovative: a must-read for planning students who have mastered the theory but have little practical experience. It is also recommended for planners, politicians and others who are constantly looking for more efficient ways of planning.

The text was written in the “scientific writing workshop landscape architecture” at the TUM Chair of Landscape Architecture and Transformation with Prof. Udo Weilacher. As part of the seminar, students select specialist literature and work together on individual book reviews.
