Lezíria do Tejo (Portugal) is an agrarian region (NUTS 3) largely overlapping the river Tagus Valley floodplain, known as Ribatejo. In spite of neighboring the Lisbon metropolitan area, Ribatejo is mostly a predominantly rural and sparsely populated area with an average population density of 54 inhabitants per km2.
Endowed with fertile soils, this region is historically related to the agricultural production, namely the growing of cereals. Irrigated maize became the main crop in the Northern side of the region after Portugal’s joining the EEC (European Economic Community), in 1986. Taking advantage of the direct support to the cereals production, the region invested in infrastructures, machinery and equipment, and experienced a productivity boom for successive years. By withdrawing direct support to the production, the CAP (Common Agriculture Policy) reforms led to the decline of the irrigated maize area, which was partially replaced by horticultural crops.
This region pioneered the introduction of precision farming in Portugal. The focus on productivity gains and cost-effectiveness, the dominance of annual arable crops, alongside with a strong and well-connected regional AKIS, largely explain the region leading technological innovation.
The study focuses on a technological innovation which is a good example of smart farming. Soil moisture probes are a smart technology that monitors soil parameters such as humidity, temperature and salinity at different soil depths in real-time.
The probes communicate the data to a software that stores, manages and integrates information from other devices, namely from in-field meteorological stations, on crop and soil features. The software delivers alerts and reports, by web and mobile apps, informing farmers and advisors about the irrigation status and needs of their crops, and also on weekly and monthly irrigation plans.
The farmers targeted by the study went from small to large family commercial farmers, who prevail in this region. The innovation path of many of them is intertwined with the region’s transition from focusing on crop productivity in the 1980s to the current paradigm of sustainable intensification aiming at tackling eco-efficiency and the competitiveness challenges both the region and its farmers are faced with. The predominant business model is bulk sell and farmers are confronted with their productions farm-gate price stagnation alongside with mounting production costs, due to the rise in input prices. Simultaneously, they face growing demands from customers, society and policies to be environmentally sustainable.
Advisory farmer-based organizations (FBO) in this region are solid and well-connected with downstream and upstream industry, as well as with the R&D sector and the high-technology companies. Hence, the study’s focus on understanding the role of FBO advisory services in disseminating and supporting different farmers’ assessment and implementation of the smart irrigation sensors.
