Water plays an essential role in the social fabric and comfort of society, as it plays an important role in our survival and subsistence, in its accessibility, in economic activities, and in the particular case of this study, in the manufacture of agricultural products and activities. In a developing society, and with the number of the human population increasing, consumerism takes place, resulting in an increasing need to use space, resources and food. Agriculture is an ancient activity that serves as the basis for ensuring the subsistence and resilience of the population, producing crops and different types of food, from vegetables, fruits, legumes, seeds, etc.… and they all have one thing in common: The existence of water. If there are fields suitable for agriculture, but there is no water, they become unusable. Water improvement and supply projects can drastically change this situation, thus stimulating agricultural production. The analysis of this case study, the largest hydroagriculture project in Europe nowadays, aims to highlight the importance of carrying out hydro-agriculture projects and the impact they can have on society, demonstrating that this project considerably increases the production of the rice harvest in Portugal through the artificial irrigation of land that previously could not be used for this purpose.
