Description

Madagascar is becoming increasingly vulnerable to the impacts of climate change and related disasters, namely drought, cyclones and flooding. While it is well-recognised that southern Madagascar has been suffering from drought for decades, it has not yet been properly acknowledged that parts of northern Madagascar are also beginning to feel the impacts of drought. Affected areas include the Diana region, Antsiranana and surrounding villages such as Namakia. Andranovondronina is also beginning to feel the impacts of drought. This is particularly affecting small-holder farmers who rely on rain-fed agriculture for both food and income. The climate of northern Madagascar is typically categorised as "transition tropical", so the onset of drought could also have major implications for the rest of the island. Northern Madagascar used to have a 6-month dry season and a 6-month rainy season, but the length of the rainy season has reduced significantly in recent years and is now locally considered a "cyclone season". More people are relying on groundwater, which is often contaminated with bacteria and excrement, leading to an increase in water-borne diseases and illnesses.

Problem Definition
Drought in northern Madagascar is disproportionately impacting small-holder farmers, who are reliant on traditional rainfall patterns for agricultural practices. It is also impacting the local population, who are facing a rise in water-borne diseases due to an increased reliance on contaminated groundwater due to drought conditions.
Success criteria
To improve access to water for drinking and agriculture in the Diana region of Madagascar by capturing rainfall during a period of cyclones and flooding. This would help the local population, and particularly small-holder farmers, to use the excessive rainfall that comes with a cyclone to support them during periods of drought.
