This publication marks the first step towards documenting the evidence of Mainstreaming Gender in Transboundary Water Management in SADC. The report highlights the unique experiences of both men and women in management of transboundary water including the decision-making processes. The case studies provided in this report seek to advance participation in transboundary water management in SADC through shared experience as more communities across boundaries begin to learn from success stories taking place in other communities. This report is also expected to build and strengthen collaboration between policy makers and communities in promoting sustainable utilisation of transboundary water for the benefit of all stakeholders. The evidence contained in this report, and the opportunities, challenges and lessons provided, should inspire stakeholders in southern Africa, and elsewhere in Africa, to get more involved in action to manage their water resources.
