This contributed volume explores flexible, adaptable, and sustainable solutions to the shockingly high costs of birth across the globe. It presents innovative and collaborative maternity care practices and policies that are intersectional, human rights-based, transdisciplinary, science-driven, and community-based.  Each chapter describes participatory and midwifery-oriented care that helps improve maternal and newborn outcomes within minoritized populations. The featured case studies respond to resource constraints and inequities of access by transforming relations between providers and families or by creating more egalitarian relations among diverse providers such as midwives, obstetricians, and nurses that minimize inefficient hierarchies within maternity care. The authors build on a growing awareness that quality and respectful midwifery care has lower costs and improved outcomes for child bearers, newborns, and providers. Topics include:  Sustainable collaborations including transfers of care among midwives and obstetricians in India, The Netherlands, Germany, United Kingdom, and Denmark Midwifery-oriented, femifocal, indigenous, and inclusive models of care that counter obstetric violence and gender stereotypes in Mexico, Chile, Guatemala, Argentina, and India Doula care and midwifery care for women of color, previously incarcerated women, indigenous women, and other minoritized groups in the global north and south Practices and metrics for improving quality of newborn and maternal care as well as maternal and newborn outcomes in disruptive times and disaster settings  Sustainable Birth in Disruptive Times is an essential and timely resource for providers, policy makers, students, and activists with interests in maternity care, midwifery, medical anthropology, maternal health, newborn health, obstetrics, childbirth, medicine, and global health in disruptive times.
