The contrast between the coast and the deep interior
In the 2023/24 school year, the proportion of students with foreign nationalities enrolled in the 1st Cycle reached 33.5% in the municipality of Odemira and 28.2% in Alvito, standing out among the highest values in Mainland Portugal, according to data released by DGEEC in 2025. In absolute contrast to the national average for basic education, which was fixed at 8.8% in the 2022/23 period, these municipalities of Southwest Alentejo and the agricultural fringe experience direct demographic pressure linked to the expansion of the agro-industrial sector.
In a study published by the Migration Observatory in 2021, the restructuring of the agro-industrial sector in Alentejo and the expansion of Alqueva's irrigation system were identified as the main structural causes for the settling of new migratory flows in previously desertified rural areas. At the national level, the average proportion of foreign students enrolled in basic education stood at just 8.8% in the 2022/23 school year, according to educational statistics indicators compiled by DGEEC in 2024.
In the geographical subsector of Alentejo Litoral, the overall total of students enrolled in public basic and secondary schools stood at 9,753 students in the 2023/24 school year, reflecting localized demographic pressures in intensive agriculture zones, according to 2025 DGEEC reports. In the broader total of the Alentejo region, the universe of students enrolled in basic and secondary schools in public schools stood at 59,482 students, representing 5.9% of the national total in the period monitored by DGEEC in 2025.
The legacy of primary school closures
By decision of the Ministry of Education led by Nuno Crato, the district of Beja registered the closure of five 1st-cycle basic schools at the start of the 2012-2013 school year, according to official records released by the Ministry of Education in 2012. This administrative measure reduced the physical proximity network, concentrating the remaining students in larger geographical school centers.
In the 2014-2015 school year, the Ministry of Education proceeded with the closure of another nine 1st-cycle basic schools in the district of Beja, covering municipalities such as Aljustrel, Alvito, Castro Verde, Cuba, Ferreira do Alentejo, and Odemira, according to Ministry of Education data from 2014. The suppression of these establishments established a centralized school network model that shaped the institutional response to subsequent population dynamics.
Simultaneously, according to the 2021 INE Census, the municipality of Odemira bucked the interior's demographic decline dynamics by registering a population increase of 13.5%, driven directly by the expansion of intensive agriculture and the attraction of immigrant labor. In the neighboring municipality of Aljezur, the proportion of foreign students enrolled in the school network reached 34.2% in the 2023/24 school year, showing that the school demographic inflation phenomenon affects the entire Southwest Alentejo fringe, according to DGEEC in 2025.
Performance indicators and social cohesion in the region
In the 2022/23 school year, the Baixo Alentejo Intermunicipal Community achieved a 1st Cycle of Basic Education completion rate within the expected time of 82%, registering the lowest value among the 24 CIMs analyzed nationally, according to DGEEC in 2024. In direct comparison, in the previous 2021/22 school year, the 1st Cycle completion rate within the expected time in the Baixo Alentejo CIM had stood at 84%, also remaining below the national average of 92% ascertained by DGEEC in 2024.
According to data ascertained by INE in 2024, the Alentejo region presented the highest monetary poverty incidence rate in Portugal, with 17.9% of the resident population living below the poverty line. In an analysis carried out by the Baixo Alentejo Intermunicipal Community in 2026, the growth of precarious immigration linked to agricultural hubs was pointed out as a factor accentuating social and income imbalances in the region, according to CIMBAL documents from 2026.
According to the OECD migration report published in 2024, the migratory flow in Portugal generated a positive impact on the workforce and mitigated the drop in the national active population, with a particular incidence in sectors with intense labor demand such as intensive agriculture in Alentejo. For families living in the 47 municipalities of the region, these numbers translate into deep asymmetries in the provision of educational services and in the integration capacity of local school networks.
The disconnect between supply and the location of new flows
The most obvious reading would be to assume that, if there are new immigration vacancies and population growth in agricultural areas of Baixo Alentejo and Alentejo Litoral, the primary school network should be in linear expansion and without the need for closures. However, cross-referenced data show that, although the arrival of immigrant families prevents the absolute closure of certain rural schools due to a total lack of children, geographical disconnect prevents this automatic growth.
This disconnect results from the distance between the location of intensive agriculture hubs — often concentrated in a few coastal or irrigated parishes — and the fixed territorial distribution of former 1st-cycle schools closed in previous decades. Added to this geographical factor are budgetary restrictions and strict class-formation ratios centrally defined by DGEEC, which continue to force the rationalization and closure of classes and isolated establishments in the rural interior.
Thus, localized demographic growth in Odemira or Alvito does not translate into the reopening of schools in the villages of the deep interior of Beja, Serpa, or Moura, where population decline remains structural. DGEEC data from 2024 and 2025 confirm that the expansion of foreign students — such as the 12 students out of a total of 22 registered in December 2023 at the São Teotónio Basic School — occurs in specific hubs, incapable of stopping the suppression of classes in the remaining parishes of the sub-region.
The structural impact on the public network of the territory
For those living in one of the municipalities of Baixo Alentejo, this dynamic means that the arrival of new population waves and the closure of classes occur simultaneously on the same regional map, without ministerial ratios or school maps being able to make pedagogical responses flexible at the local scale.
While 2025 DGEEC reports point to concentrations exceeding 30% of foreign students in specific agricultural municipalities, the 1st-cycle completion rate in the Baixo Alentejo CIM remained at 82% in 2022/23, the lowest value in the country monitored by DGEEC.
The future of the primary school network in the territory will depend on the ability to adapt class opening criteria to the new demographic realities generated by intensive agriculture, mitigating the gap between the attractive coast and the interior experiencing population retraction.
