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. This practice note argues that the Tana experience may provide a sustainable and scalable model for cross financing environmental health improvements.

La pérennité financière est essentielle aux modèles durables de l’assainissement urbain et de l’hygiène environnementale. A Antananarivo (Tana), capitale malgache, les communautés utilisent les recettes des kiosques à eau pour financer le curage de canaux, une action essentielle pour la santé publique.

This report evaluates the impacts of climate change on water and sanitation technologies in the peri-urban areas around Lake Naivasha, reviews the water resources in Lake Naivasha and considers the potential adaptations required to mitigate the impacts. Under current forecasts of climate change, the mean temperature in Kenya is predicted to increase while precipitation is expected to decrease in volume and increase in intensity, increasing the frequency and severity of droughts.

The main impacts are identified as:
Decreasing lake and ground waters: will have a significant impact as there will be higher domestic demand whilst surface water availability decreases

Increasing lake and groundwater levels is largely positive for Naivasha as there is more water for domestic and irrigation use.

Potential short, medium and long term adaptations are identified for WSUP (or the local provider), NAIVAWASS and the City Council.

This report evaluates the impacts of climate change on water and sanitation technologies in two peri-urban areas in Lusaka, Chazanga and Kanyama, and the potential adaptations required to mitigate the impacts. Under current forecasts of climate change, the mean temperature in Zambia is predicted to increase. It is less certain how average precipitation will be affected, but both floods and droughts will occur more often.
