Recife is the ninth most populous Brazilian city and encompasses the fifth largest metropolitan region in the country. It is located in the northeastern State of Pernambuco and one of the most prominent economic and business centers in the region. 

Recife is a flat city, situated at approximately 2.5 to 5 meters above sea level. Consequently, even a rising tide can lead to flooding, particularly in coastal areas. Due to its geographical and social distribution, with low-income populations residing high-risk areas, Recife places considerable emphasis on prevention and mitigation activities.
