The focus is firmly on the technical aspects of food crops; animal husbandry, agrochemicals and genetic engineering are only briefly mentioned. The manual with its strong international flavour is designed to be also used by those who normally speak or read English as their second language, using simple English terminology and phrasing, with explanations and cross references of the terminology, acronyms and terms used.
The book is divided into three sections: 1.

Increasingly, city halls have been adopting this practice to meet a demand from the communities and offer a differential to improve the quality of life in the city, contributing to the urban requalification, the environment and health. Roof farming allows the use of spaces that would otherwise be underutilized. Green ceilings reduce urban heat by absorbing solar radiation and reducing rainwater pressure in sewage systems by absorbing rainfall.
Plants can benefit from greater sunlight. Roofing can be done in raised beds or in pots. The internet is full of suggestions for making a garden in small spaces. Some vases on the window sill can produce delicious spices. Or even a small outdoor area can produce a few pounds of food. The most common form of planting is straight into the ground - just like in the fields. The soil needs to be prepared, usually by removing the top layer and covering with a soil mixture suitable for planting.
But in cities this may not be as simple.
Urban soils are at greatest risk of being contaminated, either by physical debris or toxins. It is necessary to remove glass remains, asphalt, concrete and test the soil repeatedly to ensure that there is no presence of chemicals, heavy metals or other contamination.
In the design of the Tuju Restaurant, steam architecture and Studio Croup, all the beds are filled with edible species, which are served on the menu. Elevated beds are those that stand above the surface of the ground - they may be situated directly on the ground or higher. They can be like boxes with bottoms and sides or just sides - the important thing is that they are as deep as the roots of the plants. The materials used vary between bricks, stone, wood or concrete blocks.
However, it is important to assess the source and safety of the material, as bricks and wood can contain toxic substances and contaminate soils. Although more laborious and expensive to produce, raised beds allow urban farmers to grow food despite soil contamination - and plant on asphalt or concrete, without going through expensive excavation projects.
They are also a smarter option for temporary gardens and require less investment than planting in the soil.
Like raised beds, pots are also a form of planting above ground and share many of the benefits of the former. However, the vessels are usually smaller, easily transportable, and purchased ready-made on the market. In addition, urban farmers can use urban waste to generate a multitude of potting options - such as milk cartons, tubs, wooden pallets and so on. When choosing a type of vessel, you need to take into account the volume, drainage and material.
The volume should be rooted in the plant, drainage should always be adequate and materials - particularly when using recycled or reclaimed containers - are important not to contain toxic substances. Painted or treated wood, plastics containing solvents or high density polyethylene HDPE and metals should be avoided. Hydroponics is the technique of growing plants without soil, where the roots receive a balanced nutrient solution that contains water and all the nutrients essential to the development of the plant. This may sound like a futuristic gardening concept, but hydroponics gardening is dated to the seventh century BC.
However, the popularity and mass integration of hydroponics is new. Many consider the mass use of hydroponics as the future of agriculture.
Why Urban Farms are the Future of Food Production
This is because recent studies on hydroponic agriculture have shown that it has many benefits, such as producing high quality plants, occupying less space and consuming fewer resources. In addition, hydroponic cultivation methods, in combination with vertical gardening, have helped expand the possibilities of urban gardening and indoor gardening - such as vertical farms, where plants are grown inside buildings and skyscrapers, called farmscrapers. This diagram shows the operation of hydroponic cultivation. On a smaller scale, companies like IKEA and Amazon are selling hydroponic systems that can be installed indoors.
Both the raised beds and the vases can enjoy a system of subirrigation. Also known as infiltration irrigation, it is an irrigation method where water is stored in a reservoir below the plant - which then pulls through the roots only the amount it needs.
