Climate change and gendered vulnerability: A systematic review of women's health.

Background: Climate change is an urgent global threat, with women in low- and middle-income countries (LMICs) disproportionately facing adverse health outcomes. Gendered roles, combined with socioeconomic, cultural, and environmental factors, exacerbate women's vulnerabilities, increasing the burden of mental health issues, water insecurity, sanitation challenges, and caregiving responsibilities.

Objectives: This review seeks to systematically examine the intersection between climate change and gendered health vulnerabilities, with a particular focus on women. It explores how climate change intensifies gender-specific risks and identifies pathways for integrating gender-responsive policies to mitigate both short- and long-term health impacts.

Design: Following Arksey and O'Malley's methodological framework, this systematic review mapped key concepts and evidence from studies conducted between January 2011 and January 2024. The review focuses on identifying the multifaceted health impacts of climate change on women, particularly in LMICs and marginalized communities.

Data sources and methods: A systematic search was conducted in Web of Science and Scopus databases using key terms and Medical Subject Headings related to climate change, women's health, gender inequality, mental health, water security, sanitation, and caregiving burdens. Studies were screened and selected based on relevance to the predefined criteria, with data extracted on study design, key findings, and limitations.

Results: From 2163 citations screened, 61 studies were included in the final analysis. The review highlights that climate change disproportionately affects women, exacerbating pre-existing gender inequalities. Specific impacts include heightened mental health challenges, adverse maternal and newborn health outcomes, increased water insecurity, and an intensified caregiving burden. Women in LMICs are particularly vulnerable due to reduced access to resources, healthcare, and decision-making platforms, further limiting their adaptive capacities.

Conclusion: The findings underscore the critical need for gender-responsive climate policies that address both immediate health impacts and the broader socioeconomic and environmental determinants affecting women. Effective climate adaptation strategies must integrate gender perspectives, ensuring that women's specific vulnerabilities are accounted for in policy frameworks. This review advocates for the empowerment of women through increased access to resources and decision-making, thus enhancing their resilience and adaptive capacity in the face of climate change.
