The climate crisis is also a health and humanitarian crisis, disproportionately impacting people in the world’s most climate-sensitive regions—mainly low- and low-middle income countries with the least capacity to respond. MSF and other humanitarian organizations witness the consequences daily. More frequent, intense weather events and a warming planet contribute to food and water scarcity, more severe and widespread disease outbreaks, and more injuries and preventable deaths. They also drive massive population displacement, with over 32 million people fleeing their homes in 2022 alone due to floods, drought, storms and fire—nearly triple the number displaced by violence and conflict. As global leaders convene in Dubai for the UN climate conference (COP28, 30 Nov-12 Dec 2023) we present this cross-section of work by MSF and collaborators, drawing from first-hand experience at our medical projects. Emphasizing the urgency of adapting humanitarian operations to the climate crisis, the collection also explores loss and damage through a health lens, proposes policies and practices for creating climate-resilient health organizations, and advocates for embedding fair, just ethics perspectives into humanitarian action and research on climate.

Innovation in preventing, diagnosing and treating drug-resistant tuberculosis (DR-TB) cannot come fast enough—especially given the ground lost due to the Covid-19 pandemic, and with only 1 in 3 people who have DR-TB now receiving care. The content collection linked below offers a snapshot of recent TB work by MSF and collaborators to help change this picture. The TB-PRACTECAL and endTB studies have delivered clear evidence for shorter, safer, more effective treatments against drug-resistant (DR)-TB. Faced with the many hurdles that lie ahead before these and other critical interventions can be widely accessible, other studies investigate patient/family-based models of care adapted to complex settings and neglected groups, including children. Last, several authors explore limited but potentially important options for expanding diagnosis and preventive treatment.
