Abstract. Pregnancy is a period of heightened susceptibility to external insults. In October 2024, an unprecedented torrential rain (DANA) struck South-East Spain. Concentrated in just a few hours and specific areas, it triggered severe flooding that caused 238 casualties and extensive property damage –the most devastating natural disaster in Europe so far in the 21st century.

Abstract. Air pollution is one of the most relevant threats to health worldwide. This study utilizes a combination of birth certificates for all births occurred in the capital city of Spain in 2019 and official registers of measurement stations in the 21 administrative districts. It systematically maps the influence of exposure to NO2, as a proxy for air pollution, during pregnancy, on three birth outcomes: low birth weight, prematurity, and high birth weight.
