Temporal variability of irrigation requirements of crops

In our day to day lives, we may not notice but agriculture is all around us. Not only on our meals and beverages, but on our clothes, shoes and a lot of daily objects. The need to have the most efficient usage of the cultivated land has been growing over the years. We all know that one of, if not the most, important players in this equation is water. Its correct usage in lands is crucial in order to get the maximum result of what we are cultivating. This implies that land needs to get the right amount of water in the right amount of time, and to get the best results irrigation may be absolutely necessary. The objective of the elaborate is to study the temporal variability of irrigation requirements between 1981 and 2019 in two locations near Torino (Italy) and São Paulo ( Brazil) That assessment was achieved first by a broad literature review on the concepts behind the calculations of irrigation requirements, mostly mased on FAO paper published on 1998. A previosly created model was used to get irrigation values, where it took precipitation data as one of its main keys. So, the second part was precipitation data was exctraction, manipulation and verification, to than use it as an input in the model. The final part consists in the analysis of the results shown by the model using deep statisitical concepts.
