Background and aim – This paper studies urban decline, the processin which the built environment suddenly or gradually loses its practical,technical and economic functionality, resulting in it being abandonedby its legitimate occupants and neglected by its owners for an extended period of time. Recent European examples of urban decline fromaround the globe as well as five German examples were studied. This isfollowed by a reflection on the risks for public safety and public healththat these examples show and the possible role of facility managers indiminishing these risks.Methods / Methodology – Data were collected by means of desk research and direct observations.Results – At all locations public safety and public health risks were considerable. Direct observations at five German locations show extensive urban decline.Originality –Identifying safety and health risks in abandoned buildings and connecting these issues to the facility management profession offers a new perspective on dealing with urban decay.Practical or social implications – Abandoned buildings that are easily accessible to the public generate considerable risks for public safety and health. This paper calls for a debate about how to deal with these risks. Part of the debate should be whether or not such situations should be allowed to continue.Moreover, this paper suggests a prominent role for the facility management profession in order to deal with these safety and health issues.Type of paper – Research paper.

It is of utmost importance to collect organic waste from households as a separate waste stream. If collected separately, it could be used optimally to produce compost and biogas, it would not pollute fractions of materials that can be recovered from residual waste streams and it would not deteriorate the quality of some materials in residual waste (e.g. paper). In rural areas with separate organic waste collection systems, large quantities of organic waste are recovered. However, in the larger cities, only a small fraction of organic waste is recovered. In general, citizens dot not have space to store organic waste without nuisances of smell and/or flies. As this has been the cause of low organic waste collection rates, collection schemes have been cut, which created a further negative impact. Hence, additional efforts are required. There are some options to improve the organic waste recovery within the current system. Collection schemes might be improved, waste containers might be adapted to better suit the needs, and additional underground organic waste containers might be installed in residential neighbourhoods. There are persistent stories that separate organic waste collection makes no sense as the collectors just mix all municipal solid waste after collection, and incinerate it. Such stories might be fuelled by the practice that batches of contaminated organic waste are indeed incinerated. Trust in the system is important. Food waste is often regarded as unrein. Users might hate to store food waste in their kitchen that could attract insects, or the household pets. Hence, there is a challenge for socio-psychological research. This might also be supported by technology, e.g. organic waste storage devices and measures to improve waste separation in apartment buildings, such as separate chutes for waste fractions. Several cities have experimented with systems that collect organic wastes by the sewage system. By using a grinder, kitchen waste can be flushed into the sewage system, which in general produces biogas by the fermentation of sewage sludge. This is only a good option if the sewage is separated from the city drainage system, otherwise it might create water pollution. Another option might be to use grinders, that store the organic waste in a tank. This tank could be emptied regularly by a collection truck. Clearly, the preferred option depends on local conditions and culture. Besides, the density of the area, the type of sewage system and its biogas production, and the facilities that are already in place for organic waste collection are important parameters. In the paper, we will discuss the costs and benefits of future organic waste options and by discussing The Hague as an example.
Urban renewal and urban area development projects are by nature highly complex processes involving a multiplicity of professionals, stakeholders, and conflicting interests. Adding to this complexity are the formulated ambitions and societal challenges projects have to answer to. One of these ambitions emphasizes a more inclusive planning process, involving the inhabitants in all stages of the planning process. In terms of design, another challenge is to create environments on a human scale while building in high density such as with tall residential buildings. The metropolitan area of Amsterdam intends to have 100,000 new dwellings by 2025. Most of these dwellings have to be added within the existing urban fabric, planned on obsolete inner-city brownfield locations, at the waterfront, nearby highways whereas others are going to be built in deprived neighborhoods. The deprived neighborhoods are mainly located in the postwar areas of Amsterdam, on its northern, western, and south-eastern sides. The deprived neighborhood called the Bijlmermeer located on the south-eastern side of the city, for instance was the first high-rise development project in the Netherlands. It was designed as a single project with identical high-rise buildings in a hexagonal grid surrounded with large green spaces.These deprived, modernistic neighborhoods lack the classic housing block structures with a clear articulation of buildings and street spaces. They appear to be responsible for an ‘inhuman’ scale and demonstrate the lasting impact critical design flaws can have on the daily lives of inhabitants. Hence, the question is how to develop liveable environments where people feel fully supported by building architecture and streetscape configuration. To prevent new urban area developments that will again fail to incorporate human scale, scientific methods and user input are needed to inform the practice of planning and design, and their applied design solutions. Building on two research projects (one on participatory planning and the other on neuroarchitecture research), we explore how the newly emerging field of neuroarchitecture - and the eye-tracker in particular, might enhance urban area developments on a human scale.
