Since July, a water supply network serves the villages around the park including Ampasindava, Ankingameloka, Ambararata, Ambolomanary and Antanamandriry. This initiative will give access to water to nearly 3,000 inhabitants by 2030.

Before the installation of this drinking water system, the inhabitants of Ampasindava used to drink water from traditional wells, rivers or ponds whose potability was not assured.

In addition, the inhabitants of the marine area of Nosy Hara suffer the effects of climate change in their daily life: the strength of the trade winds increases, fish production decreases and the land produces less. The supply of drinking water as an adaptation to climate change in these villages helps the communities and improves their health. Water from traditional wells is brackish, and even salty. This is partly due to the rising sea level and the karstic nature of the soil. Building resilience and mitigating health problems related to water and sanitation is essential for successful community conservation actions.

"This initiative will increase the number of tourists because the lack of hygiene infrastructure discourages tourists to visit Nosy Hara. We hope that the access to drinking water will encourage the massive arrival of visitors " confides Thèrese Fatoma. She ensures the community monitoring of small-scale fishing in Ampasindava and is part of the women's association that provides community catering for visiting tourists.

The completion of this drinking water supply network is the result of a successful collaboration between the regional authorities, the Ministry of Water, Sanitation and Hygiene, Madagascar National Parks, the Departmental Council of Finistère in France, the NGOs Experts Solidaires and Azimut. Supported by WWF, this initiative is backed by the German Development Bank (KfW).
