A literature review of the gender-differentiated impacts of climate change on women's and men's assets and well-being in developing countries por Goh, Amelia H. X.

“…In the literature reviewed, women seem to suffer more negative impacts of climate change in terms of their assets and well-being because of social and cultural norms regarding gender roles and their lack of access to and control of assets, although there are some exceptions. Empirical evidence in this area is limited, patchy, varied, and highly contextual in nature, which makes it difficult to draw strong conclusions. …”
