Without them there would be no apples, no tomatoes, no strawberries: However, there are fewer and fewer pollinators like bumblebees and bees buzzing around. In their search for the causes, researchers are taking a closer look at the ecosystem of arable land. // Millions of people live in big cities. The food they eat, usually has to be transported over hundreds of kilometres. A study is now investigating which metropolitan areas could organize their food supply more regionally. // Most of the fens in Germany have dried up and can no longer fulfil important environmental functions. A pilot project in Brandenburg has now for the first time tested their rewetting using purified waste water from sewage treatment plants. // Invasive mosquito species are on the rise in Germany: With the aid of a computer model, researchers want to predict their future distribution.

Regional food supply

Regional food supply Regional food supply on derelict land, roofs are being transformed into gardens and balconies into snack bars. "Urban gardening is a trend that encompasses many aspects", says Zasada. It is not only about healthy organic food that is grown locally, but also about social participation in the city, knowledge of gardening, education and integration. Nevertheless, the gardens on roof terraces or in backyards are not highly productive agricultural farms. They will not be able to provide enough food for the big cities. This is where initiatives such as the Nutrition Council of Berlin come in. They actively introduce a holistic view on food production into the everyday political life of the city. These initiatives, as well as associations, authorities and politicians, have now been provided with reliable scientific data thanks to the work of Zasada and his research partners. The scientist calls for a pragmatic approach to his research results. They are not a plea for the complete self-sufficiency of large cities, which is not always efficient: "We are more interested in raising awareness of how we can transform these processes sustainably through our own daily behavior as consumers." It is therefore worthwhile examining which parts of agriculture could be regionalised. According to the data, we certainly have the potential to do this in Berlin. Our own behavior as consumers is an important factor. INGO ZASADA Urban Gardening projects are an expression of social rethinking, but can only be part of the solution that leads to a sustainable food system. www.zalf.de/feld/en 16 17
