The world's population continues to grow. It is estimated that by 2050, it will approximate 10 billion people. To feed the huge population, grain production will increase by 60% to 70%. However, the global arable land is not enough. How to effectively use the urban idle space to produce food has become an important topic in the contemporary era. With the rise of urban residents' awareness of environmental protection, the deepening of green life and the rapid development of related science and technology, urban agriculture has become a trend in many countries in recent years. It not only creates employment opportunities, but also expands urban green space. "In the field of production, in the land consumption", the food is more short from the origin to the table. Energy saving and carbon reduction.
It is common for urban people to learn to be farmers in their homes, balconies, and roofs, but the upscale department stores in the center of Paris, France, also run a "air garden". The roof of the Lafayette (Lafayette) department store on Huadu street is planned by a group of agricultural engineers and architects' "Paris strawberry" company to create a huge vegetable garden, which can supply 1.8 tonnes of food to Paris citizens every year, and strawberries are the bulk of them.
The branch uses the vertical "vertical farming method", which is rammed by the current, to abandon the soil and to plant the edible crops by using the patented "biofilm" of the stratified viaduct to treat the air conditioning wastewater and rainwater with special filtration to bring the nutrients needed for the plant growth. This "soil - free, hydroponic cultivation" is based on the "biofilm", which is mainly made of animal fibers, such as waste free wool, such as waste wool, with low cost and simple method, economic and environmental protection. Wind farms and vertical farms sprang up in stores and shopping malls in Paris and other cities.
The mayor of Paris, Yida, is more encouraged by the new law. As a "gardener of public space", it is expected to create 100 hectares of vegetation walls, green roofs and other new gardens by 2020, of which 1/3 will contribute to urban agriculture (Gardening) and food production. In Paris, which is densely populated and scarce, it adds the conditions for the "real estate elimination" of food, further beautifies the urban landscape, and improves the biodiversity in the city and helps to balance the ecological environment.
On the other hand, the Metro supermarket in Berlin, the capital of Germany, CO operates with the Infarm company, which develops the Urban Indoor farm law, to promote the indoor vertical farm program, "planting fruits and vegetables directly in the supermarket", and selling it side by side so that customers can conveniently collect the fresh ingredients to buy.
Infarm is committed to producing food in a variety of "impossible" places, which make use of old containers to produce stacked modular planting boxes, in which the irrigation and nutrient supply system controlled by the Internet, and the simulation of sunlight to help plant photosynthesis LED lighting, and install multiple sensing devices in this "vertical farm". Monitoring the status of crops, consumers can also understand the growth process of food in real time through the Internet.
The vertical farm in the supermarket corridor covers only a few square meters of space in the supermarket and can extend up. "The biggest benefit is that the supermarket infrastructure is ready, without any additional construction or adjustment, only the system is installed, and it can start to operate." "It has many advantages, such as reducing food transportation, warehousing and preservation costs, and is well received by consumers.
