In San Carlos de Bariloche, fruits and vegetables come from distant producers, mainly Mendoza (1,200 km away), leading to high costs, poor freshness, and excessive single-use plastic packaging. Transport is only feasible by truck: a heavy-duty truck emits 1.2 kg of CO₂ per kilometer and carries 30,000 lettuces. With each lettuce weighing 300 g, 48 g of CO₂ (16% of its net weight) is emitted per unit during transport alone. This inefficient system results in food waste and plastic overloading municipal landfills. Our small greenhouse produces basil that remains fresh 2–3 times longer than typical products shipped from far away. No local producers offer long-lasting, scalable, and sustainable alternatives. Across Patagonia, small cities are surrounded by neglected rural areas with limited infrastructure and economic activity, often dependent on government aid or harsh jobs like sheep or cattle farming. Even in tourist towns like Bariloche, employment is seasonal and scarce. Many young people migrate to larger cities, yet youth unemployment in Argentina remains the highest in the Southern Cone, with 26% of those aged 18–24 out of work, according to the UN Development Programme. This is not only the case in Argentina—food production inefficiency is a common issue in emerging countries. We aim to change that.

Our solution is a hydroponic system powered by renewable energy with zero single-use plastics in distribution. Hydroponics provides nutrients directly to plant roots, resulting in superior organoleptic qualities and eliminating common deficiencies found in soil-grown crops. Properly designed systems reduce waste from leftovers and adverse weather, creating an efficient agricultural process and fresher, more nutritious food. In Patagonia, food is scarce for both people and livestock, and fresh produce often arrives from distant cities like Mendoza or Neuquén already deteriorating. Local production ensures fresher, healthier food for communities. The project promotes sustainable production using energy-efficient greenhouses powered by renewables with low visual impact through thoughtful design. It improves production efficiency, reduces waste, and enhances access to quality food. Also aims to educate consumers about avoiding single-use plastics and the importance of local consumption in minimizing food waste and transport emissions. Argentina's traditional agriculture often causes deforestation due to unsuitable climates. Local production protects natural ecosystems elsewhere. Our model supports sustainable consumption and production through circular economy principles each market can meet its own demand locally, using returnable packaging to keep materials in circulation and drastically reduce emissions and landfill waste.

Our intervention targets the whole community, with the greatest impact on the most vulnerable those lacking access to affordable, quality food. In Bariloche, where tourism dominates, quality food is prioritized for gastronomy. Produce often comes from distant cities like Mendoza and costs 1.5–2 times more than in Buenos Aires. With a poverty rate of 41.7% (INDEC, 2023), ongoing inflation continues to erode wellbeing, nutrition, and opportunities, reflected in poor market quality and weakened purchasing power. Our local hydroponic solution lowers production costs, allowing grocers to offer fresher products at better prices. As we diversify, we aim to supply families directly, reducing food costs further. A 200 m² greenhouse can grow 10,000 plants, producing 2,400 vegetables weekly (with space for rotation), totaling around 9,600 monthly vegetables (spinach, arugula, lettuce, swiss chard) rare in Patagonia due to climate. This can support 1,000 households monthly. The greenhouse will create jobs for four construction workers and two permanent staff in Bariloche. Additionally, three training programs will educate 240 people, offering future employment and networking. As Patagonians, we find the growing inequality deeply concerning. We aim to scale this solution to reduce emissions, promote local food ecosystems, and empower others through sustainable farming practices.
