This proposal explores the technical and environmental feasibility of using firefighting helicopters (Bambi bucket–type systems) for the aerial transport of lightweight passive solar desalination modules and seawater, aiming to produce freshwater in situ for vegetation survival irrigation at critical locations. The approach prioritizes climate mitigation, early adaptation, and the preservation of strategic vegetation, particularly under scenarios of extreme summer heat followed by dry winters.1. IntroductionExtreme heat waves reduce human performance, degrade infrastructure, and cause severe thermal stress on vegetation. When such events coincide with prolonged droughts, vegetation loss accelerates, reducing evapotranspiration and reinforcing local warming feedback loops. Vegetation loss during summer compromises ecological resilience during the following dry winter, increasing the likelihood of wildfires and ecosystem service collapse.2. Scientific FrameworkResearch in urban climatology and plant physiology shows that:Living vegetation reduces local temperatures through shading and evapotranspiration.Prolonged water stress leads to irreversible vegetation mortality, even if rainfall resumes later.Vegetation loss increases surface temperatures, soil dryness, and fire frequency.Extreme heat significantly reduces human capacity to perform complex tasks safely and effectively.Therefore, maintaining vegetation survival, even with minimal irrigation, produces a disproportionately positive climatic impact.3. Objective of the ProposalTo evaluate a rapid climate response strategy based on:Aerial transport of seawater and passive solar desalination modules.Local freshwater production for strategic irrigation.Protection of critical vegetation during extreme heat and drought events.4. Description of the Proposed System4.1 Aerial TransportUse of helicopters already deployed for wildfire suppression.Adaptation of Bambi bucket–type systems for loads that are:Flexible or semi-rigidAerodynamically stableReusable4.2 Solar Desalination ModulesPassive solar distillation systems.No electrical energy consumption.Slow but continuous freshwater production.Designed for non-potable use, specifically vegetation irrigation.4.3 Triple Thermal InsulationThe containers incorporate:External reflective layer (solar radiation reduction).Intermediate thermal insulation (evaporation control).Internal layer optimized to maintain the thermal gradient required for distillation.5. Priority ApplicationsUrban green corridors.Peri-urban forested areas.Vegetated firebreaks.Parks and areas with critical climatic functions.The goal is not intensive irrigation, but preventing vegetation mortality.6. Advantages of the ApproachReuses existing aerial firefighting infrastructure.Requires no electrical grids or major civil works.Can be rapidly deployed during climate emergencies.Simultaneously contributes to:Heat mitigationFire risk reductionHuman health protectionEnvironmental conservation7. LimitationsDoes not replace urban water supply systems.Limited scalability: strategic rather than mass deployment.Requires logistical coordination and territorial planning.These limitations define responsible use, rather than undermining feasibility.8. ConclusionUnder scenarios of accelerating global warming and recurrent droughts, adaptation strategies must be rapid, realistic, and based on existing technologies. The aerial transport of solar desalination modules for the protection of critical vegetation represents a complementary tool capable of reducing local climate impacts and preventing irreversible ecological damage before reaching climatic tipping points. “Mitigación del Calor Extremo y la Sequía mediante Desalinización Solar Transportada por Helicópteros: Protección Aérea de Vegetación Crítica”Calor extremo y sequía: un riesgo crítico para ciudades y ecosistemasDurante los últimos días se han registrado olas de calor extremo, con temperaturas que superan los límites seguros para la salud humana y la actividad laboral.La sequía prolongada amenaza la supervivencia de la vegetación urbana y periurbana, aumentando el riesgo de incendios y la degradación de ecosistemas clave.La pérdida de vegetación provoca:Incremento del efecto de isla de calor urbanoReducción de evapotranspiración y humedad ambientalDisminución de la resiliencia ecológica para enfrentar futuros eventos climáticosLa situación es urgente: sin acción inmediata, la combinación de calor extremo y sequía puede generar daños irreversibles en la vegetación, empeorando la salud urbana y ambiental.Propuesta rápida y estratégica:Transporte aéreo de agua marina y módulos de desalinización solar pasiva a zonas críticas.Producción local de agua dulce para riego de supervivencia vegetal.Mantener vegetación viva como barrera natural frente al calor, incendios y degradación urbana.Intervenciones estratégicas ahora pueden prevenir colapso ecológico y proteger la salud humana, antes de alcanzar un punto de no retorno.ResumenEl aumento sostenido de las temperaturas extremas, combinado con sequías prolongadas, está generando una pérdida acelerada de cobertura vegetal en zonas urbanas y periurbanas, incrementando el riesgo de incendios, el efecto de isla de calor y el deterioro de la salud humana y ambiental.
