Urban Agriculture and Self-Cultivation
According to UN estimates, by 2050, we will be 9.2 billion people on the planet and 70% of them will live in cities. For us, this means that we must continue searching for sustainable solutions contextualized in the urban environment.
In this case, domestic agriculture / farming is certainly one of the alternatives we mostly identify with, lying on its foundation the concepts of local production and self-sufficiency. Moreover, urban agriculture applied to commercial production has begun to gain ground, as there are already some facilities up to the level of urban greenhouses for restaurants and markets with production of their own. It also has a truly positive impact in its various aspects:
+ Reduction in feeding costs and the possibility of generating surplus receipts;
+ Increased knowledge about cultivation processes of the food we eat;
+ Stimulates self-sufficiency;
+ Saves energy by reducing the need for transportation and the respective preservation of the produces, which are usually brought from rural areas;
+ Unused and abandoned areas may be used for urban agriculture;
+ Improves the environment and air quality in the city;
+ Good use of waste for cultivation;
+ Stimulation of local dynamism, enabling the establishment of cooperatives, associations and simple exchanges of experiences among people. It is also an educational and therapeutic activity.
Like everything in life, urban agriculture also has its troubles. The main ones are the limited space and the influence of urban pollution on the plants grown.
With proper knowledge and control, we believe that Hydroponics is a great option for urban agriculture due to the possibility of growing more in less space. The absence of soil allows greater flexibility of the systems used so they can adapt to urban areas; moreover, they allow a greater turnover of plant types. There is even a general rule of the 30% applied to Hydroponics: 30% higher number of plants per m², 30% faster growth, 30% higher yields and 30% more active ingredients in plants.
