Central America is a region interconnected through 23 international watercourses and 18 transboundary aquifers. As such, the joint management of transboundary water resources often lies in a difficult balance of different interests and uses between the relevant riparian actors. Several studies have established that the participation of women in negotiation processes leads to agreements and treaties that last longer . The active participation of women in water diplomacy is therefore critical to ensure the sustainable management of shared water resources, peace and stability. However, the role of women in Central America is subject to particularly heavy patriarchal patterns, and women often occupy a secondary place in the private and public sphere. In this blog post, we discuss the opportunities and challenges of gendering water diplomacy in Central America.
