Women and girls living in the low-income communities of Dhaka lack the services and support required to practice safe menstrual hygiene. This Practice Note looks at a campaign that aimed to overcome the barriers to change.

In the Madagascan capital Antananarivo (Tana), community groups are using revenues from water kiosks and other local sources to finance a drainage canal cleaning programme, critical to public health.
