Hello! I do some research for my company and I have to find out who (companies) are the players in the Smart City market (Netherlands/Amsterdam) who have successfully implemented projects without specializing in just one solution - so here I'm looking who offer complete smart city offers that combine several solutions (e-waste, e- bike, e-mobility, smart bench, smart light, smart parking….)? Thank you!

11. Nature inclusivity

This is the 11th episode of a series 25 building blocks to create better streets, neighbourhoods, and cities. In this post, I wonder whether nature itself can tackle the environmental problems that humans have caused.
Ecosystem services
According to environmental scientists, ecosystems are providers of services. They are divided into production services (such as clean drinking water, wood, and biomass), regulating services (such as pollination, soil fertility, water storage, cooling, and stress reduction) and cultural services (such as recreation, and natural beauty). In case of nature-inclusive solutions ecosystems are co-managed to restore the quality of life on the earth in the short term and to maintain it in the long term, insofar as that is still possible.
The green-blue infrastructure
The meaning of urban green can best be seen in conjunction with that of water, hence the term green-blue infrastructure. Its importance is at least fourfold: (1) it is the source of all life, (2) it contributes substantially to the capture and storage of CO2, (3) 'green' has a positive impact on well-being and health; (4) it improves water management. This post is mainly about the third aspect. The fourth will be discussed in the next post. 'Green' has many forms, from sidewalk gardens to trees in the street or vegetated facades to small and large parks (see collage above).
Improving air quality
Trees and plants help to filter the water itself. They have a significant role to play in managing water and air pollution. Conifers capture particulate matter. However, the extent to which this occurs is less than is necessary to have a significant impact on health. Particulate matter contributes to a wide range of ailments. Like infections of the respiratory system and cardiovascular disease, but also cancer and possibly diabetes.
Countering heat stress
Heat stress arises because of high temperature and humidity. The wind speed and the radiation temperature also play a role. When the crowns of trees cover 20% of the surface of an area, the air temperature decreases by 0.3oC during the day. However, this relatively small decrease already leads to a 10% reduction in deaths. Often 40% crown area over a larger area is considered as an optimum.
Reduce mental stress and improve mood
According to Arbo Nederland, 21% of the number of absenteeism days is stress-related, which means approximately a €3 billion damage. A short-term effect of contact with nature on stress, concentration and internal tranquility has been conclusively demonstrated. The impact of distributing greenery within the residential environment is larger than a concentrated facility, such as a park, has.
Strengthening immune function via microbiome
The total amount of greenery in and around the house influences the nature and quantity of the bacteria present. This green would have a positive effect on the intestinal flora of those who are in its vicinity and therefore also on their immune function. The empirical support for this mechanism is still rather limited.
Stimulate physical activity
The impact of physical activity on health has been widely demonstrated. The Health Council therefore advises adults to exercise at least 2½ hours a week. The presence of a green area of at least ¼ hectare at 300 meters from the home is resulting more physical activity of adults in such areas, but not to more activity as a whole.
Promoting social contact
Well-designed green areas near the living environment invite social contacts. For instance, placement of benches, overview of the surroundings and absence of traffic noise. The state of maintenance are important: people tend to avoid neglected and polluted areas of public space, no matter how green.
Noise reduction
Vegetation dampens noise to some extent, but it is more important that residents of houses with a green environment experience noise as less of a nuisance. It is assumed that this is due to a mechanism already discussed, namely the improvement of stress resistance because of the greenery present.
Biophilic construction
For years buildings made people sic. A growing number of architects want to enhance the effect of 'green' on human health by integrating it into the design of houses and buildings and the materials used. This is the case if it is ensured that trees and plants can be observed permanently. But also, analogies with natural forms in the design of a building
The 'Zandkasteel', the former headquarters of the Nederlandse Middenstandsbank in Amsterdam, designed by the architects Ton Alberts and Max van Huut, is organically designed both inside and outside, inspired by the anthroposophical ideas of Rudolf Steiner. The (internal) water features are storage for rainwater and the climate control is completely natural. The building has been repurposed for apartments, offices and restaurants.
Green gentrification
Worldwide, there is a direct correlation between the amount of greenery in a neighborhood and the income of its residents. Conversely, we see that poorer neighborhoods where new green elements are added fall victim to green gentrification over time and that wealthier housing seekers displace the original residents.
The challenge facing city councils is to develop green and fair districts where gentrification is halted and where poorer residents can stay. Greening in poor communities must therefore be accompanied by measures that respect the residential rights and aim at improving the socio-economic position of the residents.

10. Health

Most important causes of death worldwide (Source: The Lancelet, le Monde)
This is the 10th episode of a series 25 building blocks to create better streets, neighbourhoods, and cities. In this post, I mainly focus on health problems which are directly related to the quality of the living environment
Are cities healthy places?
According to the WHO's Global Burden of Diseases Study, 4.2 million deaths worldwide each year are caused by particulate matter. The regional differences are significant. Urban health depends on the part of the world and the part of the city where you are living. More than 26 million people in the United States have asthma and breathing problems as a result. African-American residents in the US die of asthma three times as often as whites. They live in segregated communities with poor housing, close to heavy industry, transportation centers and other sources of air pollution.
Globally, the increasing prosperity of city dwellers is causing more and more lifestyle-related health problems. Heart disease, and violence (often drug-related) has overtaken infectious diseases as the first cause of death in wealthy parts of the world.
The Netherlands
Very recently, Arcadis published a report on 'the healthy city'. This report compares 20 Dutch cities based on many criteria, divided over five domains. The four major cities score negatively on many aspects. In particular: healthy outdoor space, greenery, air quality, noise nuisance, heat stress and safety. Medium-sized cities such as Groningen, Emmen, Almere, Amersfoort, Nijmegen, and Apeldoorn, on the other hand, are among the healthiest cities.
In Amsterdam, the level of particulate matter and nitrogen dioxide (NO2) in 2018 exceeded World Health Organization standards in many streets. The GGD of Amsterdam estimates that 4.5% of the loss of healthy years is the result of exposure to dirty air.
Collaborative measuring air quality
In various cities, groups of concerned citizens have started measuring the quality of the air themselves. A professional example is the AiREAS project in Eindhoven. An innovative measuring system has been developed together with knowledge institutions and the government. Sensors are distributed over the area of the city and the system provides real-time information. The AiREAS group regularly discusses the results with other citizens and with the city government. The measurement of the quality of the air is supplemented by medical examination. This research has confirmed that citizens in the vicinity of the main roads and the airport have an increased risk of mortality, reduced lung function and asthma.
The AiREAS project is linked to similar initiatives in other European cities. Occasionally the data is exchanged. That resulted in, among other things, this shocking video.
Future?
Could the future not be that we are busy doing the obvious things for our health, such as walking, cycling, eating good food and having fun and that thanks to wearables, symptoms of diseases are watched early and permanently in the background, without us being aware of it? The local health center will monitor and analyze the data of all patients using artificial intelligence and advise to consult the doctor if necessary. An easily accessible health center in one's own neighborhood remains indispensable.

9. Road safety

This is the 9th episode of a series 25 building blocks to create better streets, neighbourhoods, and cities. Casualties in traffic are main threats to the quality of the living environment. ‘Vision zero’ might change this.
Any human activity that annually causes 1.35 million deaths worldwide, more than 20 million serious injuries, damage of $1,600 billion and is a major cause of global warming would be banned immediately. Except for the use of the car. This post describes how changes in road design will improve safety.
The more public transport, the safer the traffic
Researchers from various universities in the US, Australia and Europe have studied the relationship between road pattern, other infrastructure features and road safety or its lack. They compared the road pattern in nearly 1,700 cities around the world with data on the number of accidents, injuries, and fatalities. Lead researcher Jason Thompsonconcluded: <em>It is quite clear that places with more public transport, especially rail, have fewer accidents</em>. Therefore, on roads too public transport must prioritized.
The growing risk of pedestrians and cyclists
Most accidents occur in developing and emerging countries. Road deaths in developed countries are declining. In the US from 55,000 in 1970 to 40,000 in 2017. The main reason is that cars always better protect their passengers. This decrease in fatalities does not apply to collisions between cars and pedestrians and cyclists, many of which are children. Their numbers are increasing significantly, in the US more than in any other developed country. In this country, the number of bicycle lanes has increased, but adjustments to the layout of the rest of the roads and to the speed of motorized traffic have lagged, exposing cyclists to the proximity of speeding or parking cars. SUVs appear to be 'killers'and their number is growing rapidly.
Safe cycling routes
In many American cities, paint is the primary material for the construction of bike lanes. Due to the proximity of car traffic, this type of cycle routes contributes to the increasing number of road deaths rather than increasing safety. The Canadian city of Vancouver, which doubled the number of bicycle lanes in five years to 11.9% of all downtown streets, has the ambition to upgrade 100% of its cycling infrastructure to an AAA level, which means safe and comfortable for all ages and abilities. Cycle paths must technically safe: at least 3 meters wide for two-way traffic; separated from other traffic, which would otherwise have to reduce speed to less than 30 km/h). In addition, users also need to feel safe.
Street design
Vision Zero Cities such as Oslo and Helsinki are committed to reducing road fatalities to zero over the next ten years. They are successful already now: There were no fatalities in either city in 2019. These and other cities use the Vision Zero Street Design Standard, a guide to planning, designing, and building streets that save lives.
Accidents are often the result of fast driving but are facilized by roads that allow and encourage fast driving. Therefore, a Vision Zero design meets three conditions:
• Discouraging speed through design.
• Stimulating walking, cycling and use of public transport.
• Ensure accessibility for all, regardless of age and physical ability (AAA).
The image above shows a street that meets these requirements. Here is an explanation of the numbers: (1) accessible sidewalks, (2) opportunity to rest, (3) protected cycle routes, (4) single lane roads, (5) lanes between road halves, (6) wide sidewalks, (7) public transport facilities, (8) protected pedestrian crossings, (9) loading and unloading bays, (10) adaptive traffic lights.
Enforcement
Strict rules regarding speed limits require compliance and law enforcement and neither are obvious. The Netherlands is a forerunner with respect to the infrastructure for bikes and pedestrians, but with respect to enforcement the country is negligent: on average, a driver of a passenger car is fined once every 20,000 kilometers for a speeding offense (2017 data). In addition, drivers use apps that warn of approaching speed traps. Given the risks of speeding and the frequency with which it happens, this remissing law enforcement approach is unacceptable.
