Madagascar stone river water storage reservoir

How many basins does Madagascar have?

Madagascar has five main basins and most surface waters drain from the Central Highlands across two of the basins. The Western slope drains from the Central Highlands to the Mozambique Channel and contains the largest and longest rivers, including the Betsiboka.

Where can I find reliable data on the hydrogeology of Madagascar?

It is difficult to find good, reliable data on the hydrogeology of Madagascar. Even if they exist, groundwater data are often hard to access from the organisations that hold the data, such as government, international organisations, NGOs, and drilling and engineering companies.

Does Madagascar have a water supply?

Although Madagascar has numerous rivers, lakes, and aquifers, which make up its water resources, 49 % of the population does not have access to a basic water supply (Godfrey, 2018).

Does Madagascar have a river?

Eastern Madagascar receives steady rainfall year-round. Precipitation in southern Madagascar is more erratic and rivers are not perennial, leading to seasonal water stress. There are five main basins and most runoff drains through the Western and Eastern slopes, including the Betsiboka on the Western slope, which is Madagascar’s longest river.

How can Madagascar improve water conservation?

Madagascar should focus on developing and implementing water saving infrastructure for different types of water use; improve water management, by rationalizing local water pricing structures to ensure better cost recovery and greater water conservation in Madagascar.

What are the characteristics of surface and groundwater resources in Madagascar?

Groundwater potential is lower in the Central Highlands and much of eastern Madagascar, whereas alluvial aquifers throughout western Madagascar are extremely productive. This section summarizes key characteristics of surface and groundwater resources.
