In cities, green space is still sometimes scarce. In fact, green spaces seem to disappear in urban areas. Such spaces are often taken away for new houses or business premises. Moreover, gardens in a city are tiled a lot. It also appears that many municipalities have cut back on municipal green space. They save money as a result, of course, but it is not conducive to green spaces. There are even people who buy solar panels and place on their previously green roof. For greenery, again, this is not good, while it is important to invest in a green city.
Usually cities are warmer than villages. This is because stone houses, squares and streets absorb a lot of heat, while only slowly releasing it. After a summer day, it will often stay as much as five or 10 degrees warmer at night in a city than in the countryside. There are many reasons to prevent heat in urban areas. For one, excessive heat can threaten the health of vulnerable groups. For example, heat waves cost lives. In addition, labor productivity will also drop during hot months. In addition, there are negative impacts on drinking water supplies and water quality.
Greenery will also contribute to social cohesion. This is particularly done through neighborhood green spaces, which can include allotments and parks. In these types of spaces, neighborhood residents can come together and collaborate on green space. Neighborhoods where residents have more contact typically experience less nuisance, crime and degradation. This is according to a study by Jan Vreke. Neighborhood green space should therefore actually be a place where neighbors can meet informally. In principle, this could even be a grown roof can be where local residents can tend the plants and flowers.
In addition, greenery helps reduce stress, as many studies have already shown. For example, Dutch researchers showed that people are healthier if their living environment contains more greenery. For example, children in green neighborhoods are 15 percent less likely to be overweight. This was found to be particularly strong within disadvantaged groups. For example, children in poor green neighborhoods are 10 percent less likely to be prescribed the drug Ritalin than children who live and live in equally poor but less green neighborhoods. So greenery makes people healthier and improves well-being.
