This study delves into Green Infrastructure (GI) planning in Brindisi, Italy, evaluating its influence on urban air quality and thermal comfort. Employing an LCZ-centered Geographic Information System (GIS)-based classification protocol, the prevalence of LCZ 6 (Open low-rise) and LCZ 2 (Compact mid-rise) is highlighted. Despite generally low PM₁₀ levels in Brindisi, intermittent NOx spikes surpassing WHO and EU standards pose health risks. Within LCZ 2, diverse GI interventions (green walls, hedges, trees) were tested, with green walls emerging as the most effective, albeit falling short of expectations, while trees exhibited adverse air quality impacts. LCZ 6 demonstrated enhanced air quality attributed to wind patterns, GI, and urban canyon improvements. Thermal comfort analysis consistently revealed positive outcomes across various GI types, reducing discomfort by a minimum of 10%. The study emphasized GI’s favorable comfort impact on sidewalks but cautioned against trees in street canyons with aspect ratios exceeding 0.7, heightening pollutant levels and implying increased exposure risks. Conversely, street canyons with lower aspect ratios displayed variable conditions influenced by prevailing regional wind patterns. In conclusion, the integrated assessment of LCZ and GI holds promise for informed urban planning, guiding decisions that prioritize healthier, more sustainable cities. This underscores the crucial need to balance GI strategies for optimal urban development, aligning with the overarching goal of promoting urban well-being and sustainability.

Los eventos extremos de origen meteorológico son uno de los principales desafíos que presentan las ciudades en la actualidad. Adquieren gran relevancia debido a que actúan como potenciales peligros a la infraestructura, los servicios urbanos y la población. En un contexto de cambio climático comprender los eventos extremos es fundamental para reducir su impacto en las áreas urbanas. El objetivo del trabajo es analizar el evento de bow-echo ocurrido en Argentina el 16 de diciembre de 2023, verificar su carácter extremo y definir su impacto en Bahía Blanca.

Las ciudades resilientes y sostenibles son espacios que tienen la capacidad de adaptarse a los problemas implementando estrategias que planteen prácticas de cambio en las formas de vida de los habitantes, respetando la naturaleza y haciendo un uso eficiente de los recursos. El objetivo de este artículo es presentar una propuesta de investigación desde la Geografía Física Aplicada que se orienta a la aplicación de Soluciones basadas en la Naturaleza (SbN) en ambientes urbanos del suroeste bonaerense como aporte a la sostenibilidad y resiliencia urbana. Se expone el marco conceptual, las hipótesis y las líneas de trabajo, que se enmarcan bajo el Objetivo de Desarrollo Sostenibles (ODS) 11 de Naciones Unidas “para ciudades más inclusivas, seguras, resilientes y sostenibles”. Estas se centran en: patrones de urbanización y sostenibilidad ambiental, eventos climáticos extremos en el contexto de cambio climático, dinámica hídrica y pluvial en las ciudades e infraestructura verde como parte de las SbN.

Conocer el comportamiento de las heladas resulta vital para la toma de decisiones en el sector agropecuario. En este trabajo se analiza la frecuencia, duración, intensidad, y fecha de ocurrencia de las heladas agrometeorológicas en el suroeste de la provincia de Buenos Aires (2013-2017). Se aplican procedimientos estadísticos, interpolación (Distancia Inversa Ponderada) y se realiza cartografía aplicada. Como resultado se observa que, la distribución espacial de las heladas no es homogénea. Las heladas tempranas y tardías se manifiestan en toda la región y principalmente en el sector oeste, afectando, en mayor medida, a las localidades más continentales.

Climate change is intensifying and altering the frequency of extreme weather events globally. Argentina, in particular, has witnessed a surge in such events, especially during summer. Recent decades have seen devastating wildfires, prolonged droughts, intense heat waves, and severe weather phenomena, including bow echoes and tornadoes, across much of the country. This study focuses on identifying and characterizing severe summer events in Bahía Blanca in terms of meteorological conditions and their effects on the population to understand associated risks and inform future mitigation and adaptation strategies.Three events stand out as particularly severe. First, on December 16, 2023, a bow echo event with winds exceeding 150 km/h and 60 mm of precipitation in just two hours. Second, between January 23 and February 1, 2024, the city experienced its longest recorded heat wave, with temperatures soaring above 40°C. Finally, on February 2, 2025, a rapidly developing convective storm produced devastating hail and winds over 110 km/h. These three events resulted in loss of life, critical infrastructure damage, vegetation loss, post-traumatic stress among residents, disruption of essential services for several weeks, and widespread property damage affecting nearly the entire city.The occurrence of these three severe events within just two summers underscores the increasing frequency and intensity of such phenomena. This highlights the critical need for effective early warning systems and clear communication protocols to minimize risk. Furthermore, investing in resilient infrastructure is crucial for reducing short-term and long-term damage. Finally, developing a comprehensive climate change adaptation plan is essential for Bahía Blanca to address these escalating challenges effectively.
