Greenhouses provide numerous advantages in the production of fruits and vegetables, offering the perfect climatic conditions for each species. However, building a greenhouse requires not only taking into account budgetary issues, but also environmental and regional regulations, and the licenses required by authorities to build these structures in rural areas.
The companies that want to embark on this process must first obtain a land-use certificate issued by municipal planning. This means that the plot must be classified as land for agricultural purposes.
If the greenhouse is going to have an irrigation system, it is essential to get a permit to use water sources for this activity, which must be processed before the corresponding Regional Autonomous Corporation (CAR). In turn, it is necessary to have a discharge permit for wastewater or pesticides, according to the institution's researcher, Jorge Palacio.
The requirements to achieve this include the establishment of a fallow zone to an agrochemical deactivation well. In addition, the greenhouse structure must be a minimum of 30 meters away from water sources.
According to Palacio, the cost of constructing a traditional greenhouse in guadua calentana (a type of giant bamboo) using six caliber plastic, couplings, irrigation tape, and including labor ranges between 15,000 and 18,000 dollars per square meter, depending on transport.
Since greenhouses allow creating artificial climatic conditions, they can increase the profitability of a crop by improving its growing conditions, or even being able to grow them out of season. They also enable the production of fresh vegetables throughout the year.
