| Popis: | The increase in population, the excessive use of arable land, the scarcity of water, the energy shortage and consequently the deforestation and loss of fertile land is affecting the agricultural environment in a negative way. Given the increase in climate change and its negative effects is it important to study the viability of alternatives that help to minimize these issues. With each passing year, it is becoming more and more important to prioritise sustainability in all possible areas. For that reason, this thesis focuses on the study and analysis of the energy consumption of traditional cultivation systems. In detail, the rate of cost for electricity has been determined in order to model the food processing and its storage in controlled ambient temperature and relate the energy consumption of each processing phase to the produced kilogram of product and to the type of crop. Therefore, it has been done research on the agricultural sector both in an energetically and environmentally way. Once given a general idea on this, it has been studied different types of cultivation to see its advantages and disadvantages. Having understood those benefits and withdrawals, we have seen the importance of investing on other types of cultivation rather than open field cultivation such as greenhouses or vertical farms, a concept to produce vegetables in city centres and therefore, reduce transportation and deforestation to minimize pollution and what it entails. Specifically, it has been modelled a hypothetical greenhouse system located near Naples. It has been calculated the thermal load, the energy consumption, and the rate of cost for electricity per kilogram produced. Afterwards, it has been analysed and discussed the results obtained comparing them to the ones obtained if it was located in other countries. Thanks to this, it has been possible to see how the influencing factors affect the rate of cost for electricity |
