Development of regional microeconomies in the production of essential oils harvested in mining soils

Argentina and Colombia share arid environments where soil desertification is the main limiting factor. As an innovative contribution, the promotion of microeconomies from the use of plant biomass produced in remediated soils was proposed.

Context of the story

The mining activity developed in both regions competes for the use of soils and prevents the production of food for fresh consumption due to the potential risk of phytoextraction of heavy metals. In turn, the traction and economic prosperity generated during the mining operation collapses at the closure of the mine. In this context, we proposed a biotechnological alternative to rhizorestation of landfill areas without vegetation cover to mitigate the impact on agricultural productivity of communities adjacent to mining areas, in a context of family farming, promoting regional microeconomies and their access to new markets, based on the production of cosmetics and bio-inputs from organic products.

The implemented initiative

Regional microeconomics were promoted through the use of plant biomass cultivated in mining soils for the production of essential oils and by-products of high added value. Niche markets for oils and their derived bio-inputs were identified and a pilot phytoremediation area based on aromatics was implemented in zones with mining activity or heavy metal contamination. The main objective was to strengthen regional microeconomies through the family production of aromatic species and essential oils from Argentina and Colombia, increasing the productivity and sustainability of production systems and the use of raw materials in the framework of phytoremediation of mining soils.

The technological solution

1. MARKET STUDY. It assessed the production of essential oils in Latin America and the Caribbean (LAC) and the potential mining areas to be intervened. A study of national and international market projections was carried out and the socioeconomic and environmental impact of the proposed productive developments was assessed.
2. REMEDIATION OF MINING SOILS USING AROMATICS. The bioprospecting of new native species tolerant to heavy metals that are of biotechnological interest was carried out, they were nurseryized and produced on a pilot scale in our own nursery. Soil remediation tests were carried out and its behavior was evaluated up to the development of bio-inputs from biomass products. A mine closure protocol was designed.
3. DEVELOPMENT OF BIOINSUMS From the oils obtained from the biomass, cosmetics and bio-inputs for organic agriculture were developed.
4. DISSEMINATION OF KNOWLEDGE. Based on the dynamics of field schools, tools were designed for the dissemination and democratization of the knowledge generated.

Results

The direct beneficiaries are 600 family farmers (250 from Argentina and 350 from Colombia). In Argentina, about 60 families belonging to 18 organizations were directly benefited, promoted through the Municipality of Santa Rosa and the Secretary of Family Agriculture of the province, in the towns of Santa Rosa, General Pico, Toay, Cachirulo and Anguil. In Colombia, the beneficiaries correspond to 150 members associated with the Kankuamos Agroecological Producers Cooperative and 200 family farmers from new associations in the Caribbean region (Serranía del Perijá, Department of Cesar). The indirect beneficiaries are the rest of the actors in the value chain (distributors, merchants and the province.
