Même dans les quartiers urbains desservis par réseaux d’eau, les ménages les plus pauvres rencontrent des difficultés de branchement. La plupart du temps, les formalités représentent l’ obstacle majeur. À Maputo (Mozambique), le projet Tchemulane travaille avec des groupes communautaires et le service des eaux pour aider les consommateurs les plus pauvres à avoir accès au branchement domestique.

When constructing shared facilities like water kiosks and communal toilets, it is critical to identify locations that maximise usage and thus ensure financial viability. This note describes a procedure, developed in Antananarivo, for identifying viable infrastructure locations.

Il est essentiel de bien choisir l’emplacement des infrastructures communautaires telles que les bornes fontaines ou les toilettes publiques pour maximiser leur utilisation et par-là assurer leur viabilité financière. Cette note décrit une procédure élaborée à cet effet à Antananarivo pour identifier la localisation des infrastructures.

Quando se constroem infraestruturas partilhadas tais como quiosques de abastecimento de água e latrinas comunitárias, é fundamental identificar locais que maximizem a sua utilização e garantam a viabilidade financeira. Esta nota descreve um procedimento, desenvolvido em Antananarivo, para a identificação de locais viáveis para as infraestruturas.

Climate change is happening, and the urban poor are extremely vulnerable to its impacts. Demand for water and sanitation services in low-income urban areas is likely to increase, while flooding and water shortages may become more frequent. This Practice Note outlines a rapid assessment method for planning the climate-proofing of a city’s water and sanitation services.

Le changement climatique est une réalité à laquelle les communautés urbaines pauvres sont très vulnérables. Si la demande pour les services d’eau et d’assainissement augmenteront probablement, les inondations et les pénuries d’eau risquent de devenir plus fréquentes, d’où la nécessité pour les fournisseurs de service d’agir maintenant.

As alterações climáticas estão a acontecer e as populações mais desfavorecidas das zonas urbanas são muito vulneráveis aos seus impactos. É muito provável que a procura por serviços de abastecimento de água e de saneamento em áreas urbanas de baixo rendimento aumente e as cheias e a escassez de água poderão tornar-se mais frequentes. Os provedores de serviços devem agir agora.

This report explains the background and theory of Integrated Water Resource Management (IWRM), how it is implemented and synthesises the main criticisms. The document reviews how IWRM is relevant to the supply of drinking water and sanitation, urban areas and low income countries. Then reviews when IWRM is relevant to WSUP.

This report evaluates the impacts of climate change on water and sanitation technologies in the informal and peri-urban areas in Antananarivo and considers the potential adaptations required to mitigate the impacts. The vulnerabilities and adaptations were determined based upon a field visit, a vulnerability assessment and a literature review. Under current forecasts for Antananarivo mean temperatures, rainfall and rainfall intensity are predicted to increase. There will be more frequent storms and cyclones will decrease in frequency but increase in intensity. This is likely to increase the volume of runoff, raise river levels and increase the speed of flood onset; resulting in an increase in flooding from both the river and the drains.

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.
