CLIMACH is a research interest group that brings together researchers from across the London School of Hygiene & Tropical Medicine (LSHTM) with expertise in climate change and maternal and child health. CLIMACH is also a forum for collaboration which aims to: develop an environment for knowledge exchange, leverage research impacts across the School and support and maintain expertise in climate and maternal health research. By building a collective base of knowledge and expertise, the group strives to accelerate research across LSHTM, and beyond, to tackle the urgent challenges of the climate crisis and make a difference in the health of women and children in a changing climate.
