ECA Studies pave the way to combating flooding in Honduras Format San Pedro Sula is a city in Northern Honduras. The area has always been prone to tropical storms and flooding; however in recent years the effects of climate change, land use change and deforestation have led to worsening problems. A growing population and increased intensity of storms have added further strain on the existing drainage systems and the city has suffered increasingly from floods. “Climate change has significantly increased the risk of catastrophic floods,” explained Mayor Armando Calidonio. “These floods have grown in intensity and turned into much stronger events that reach neighborhoods and areas that weren’t exposed before. We’re seeing the concentration of rainfall into more aggressive storms that in general, even in the most developed areas, are causing the rainwater drainage systems to collapse.”
