In this context, social technologies emerge as viable alternatives for the rational use of water resources. The present study aimed to evaluate the vegetative development and productivity of lettuce (Lactuca sativa L.) grown in beds with a capillary rise irrigation system, comparing it to the conventional drip irrigation system, at the School Farm of the Federal Institute of Rio Grande do Norte, Ipanguaçu Campus. The experiment was conducted in soil classified as Eutrophic Fluvic Neosol, using six beds, three with capillary rise irrigation and three with drip irrigation, over a 45-day cycle. Productive variables such as total fresh mass, number of leaves, plant diameter, leaf area, leaf and root size were evaluated, in addition to the total volume of water applied in each system. The results showed that the drip irrigation system presented slightly higher values for most productive variables; however, it required a water volume approximately 97% greater than the capillary rise system. Despite this difference, the beds with capillary rise achieved productivity very close to that of drip irrigation, with a difference of less than 5% in total fresh mass, demonstrating high efficiency in water use. It is concluded that capillary rise irrigation constitutes a viable and sustainable alternative for lettuce production in semi-arid regions, especially when integrated into productive home gardens within the context of family farming, as it promotes efficient water use, food production for self-consumption, and the strengthening of food security for rural families.

The research was carried out from November 2024 to February 2025, using tools such as transect walks, preparation of a farm sketch, SWOT analysis, problem prioritization matrix, problem tree, and time-use matrix. The results revealed weaknesses related to nutritional, sanitary, and reproductive management of the animals, as well as structural limitations and difficulties in accessing credit and technical assistance. On the other hand, important potentialities were identified, including the farmer’s empirical knowledge, the diversity of species raised, and the use of local resources, which contribute to greater productive autonomy and sustainability. It is concluded that the active participation of the farmer in the diagnostic process enables the construction of strategies consistent with the local reality, strengthening the resilience of the production unit and promoting sustainable rural development.

Agroecology combines traditional knowledge and scientific advances in recent decades to produce clean, pesticide-free food, demanding profound changes in agricultural education. This model prioritizes technologies that work with nature, preserving the balance between living beings and the environment. Agroecological production in the country connects academic activities, rural extension, and research, strengthening networks that legitimize and expand this relationship between humans and nature. IFRN - Ipanguaçu Campus offers integrated and subsequent technical courses in agroecology. If necessary, evaluate the Integrated Technical Course in Agroecology, analyzing the trajectories of students and graduates to promote improvements in professional training. This study aimed to analyze data from classes enrolled between 2012 and 2025 in the Integrated Technical Course in Agroecology offered by the Federal Institute of Education, Science, and Technology of Rio Grande do Norte - Ipanguaçu Campus. For this, an exploratory research was conducted using the official data from the Academic Secretariat of the Campus. Data obtained from the Academic Office show that female students are more likely to participate in the Integrated Technical Course in Agroecology. Between 2012 and 2025, the Integrated Technical Course in Agroecology at the IFRN Ipanguaçu Campus showed a predominance of female students in virtually all classes analyzed. The data demonstrate that women accounted for the majority of both enrollments and completions, reflecting a trend toward greater female participation in courses related to agricultural sciences.
