Echi dal passato: i dinosauri e la crisi climatica | Alfio Alessandro Chiarenza | TEDxPadova
TEDx Talks· 2025-06-25 16:14
[Musica] Sono un paleontologo e studio i dinosauri. Molti adulti e forse anche qualche ministro dell'istruzione si starà domandando perché studiare qualcosa di così futile, a cosa serve. Bene, oggi vorrei portarvi in un viaggio attraverso creature, mondi, climi, ambienti del passato per mostrarvi che la paleontologia non è del tutto inutile.Viviamo, come potete vedere anche da questo sfondo, in tempi attraversati da eventi climatici estremi. Questi sono causati da riscaldamento globale antropogenico, è una ...

Water Resource Management & Agriculture - FAO warned over a decade ago that optimizing water use, especially in agriculture where over 70% of human water consumption occurs, is crucial to ensure food production for 10 billion people by 2050 [1] - The company's technology helps farmers use less water while increasing crop yields [7] - In Veneto, Italy, if the technology were universally adopted, approximately 120 million cubic meters of water could be saved each summer, equivalent to the city of Padua's water usage over 5 years [14] Technology & Innovation - A research group in the US and the University of Padua discovered elements to solve the problem of managing unseen underground water 15 years ago [2] - The technology utilizes cosmic rays, specifically neutrons, to measure soil moisture; neutrons are absorbed by hydrogen in water, allowing the device to indirectly measure water content [8][10][11] - The device, resembling a ping pong paddle, measures water content in an area of over 5 acres (approximately 250 meters in diameter) up to 50 cm deep when installed 2 meters above ground [12][13] Environmental Impact & Sustainability - The technology aids in identifying water leaks in cities without excavation, facilitating faster repairs and infrastructure investment planning [8][14] - The company measures Snow Water Equivalent (SWE) to help governments and organizations manage water resources, deciding when to store or release water in lakes and rivers [15][16] - Nuclear physics research from 15 years ago has become the foundation for a sustainability solution, preserving water resources [17]
