Training and sustainability in the semi-arid region: setting up an agroforestry technical unit

Abstract

The Floema project, developed by Engineers Without Borders - Natal branch, aims to promote agroecological and sustainable practices in rural communities in the semi-arid region of Rio Grande do Norte, with a focus on food security and climate resilience. The main objective is to set up an Agroforestry System Technical Demonstration Unit in the community of Catolé, in Lajes Pintadas/RN, integrating social technologies such as the use of biofertilizer from biogas and the use of wastewater, related to the Biodigestor and Fertile Sanitation projects respectively. The methodology adopted follows the principles of Popular Engineering, combining local knowledge with engineering and nutrition techniques. The two-year project (2024-2025) began with a socio-economic, environmental and nutritional diagnosis, followed by biochemical analyses of the soil, biofertilizer and reuse water. The training workshops include environmental education, agroforestry and nutritional practices, carried out with the local community. So far, challenges such as water scarcity and a lack of skilled labor have been identified, limiting the adoption of more complex practices. However, the proposed training courses aim to enable farmers to overcome these barriers and promote greater sustainability. The project is an opportunity to improve agricultural and livestock production, as well as raising the quality of life and food security of the families involved.
