In late August 2026, Prime Minister Sébastien Lecornu visited Mayotte with several ministers to announce measures accelerating post-cyclone Chido reconstruction. Seventeen municipalities now receive individual monitoring. In total, €4 billion has been committed under the 2026-2031 five-year strategy, but concrete delivery on the ground is now the focus.
Water, the absolute priority: €730 million over six years
The water envelope for 2025-2031 is set at €730 million. First measures are immediate: installation of 90 water tanks in schools, support for 13,000 vulnerable households from January 2027. The Iron Bé desalination plant is expected in Q1 2028, with a third hill reservoir due by end-2027. Water access remains the most acute challenge for reconstruction.
Education: 308 classrooms and two new high schools
The plan provides for 308 new classrooms for the 2026-2027 school year and two additional high schools — including one in Longoni specialising in construction trades. By 2030, 3,600 additional middle-school places and 6,400 high-school places will be created to absorb the archipelago's rapid demographic growth.
An economy driven by reconstruction
One year after Chido, Mayotte's economy presents a paradoxical profile. Imports have surged 26%, exceeding €300 million for the first time, driven by construction and reconstruction demand. Inflation is stable at 1.3%. But the IEDOM notes that "growth rests primarily on an extraordinary reconstruction effort and public spending" — a fragile base if not eventually replaced by a diversified productive economic fabric.
Health and security on the roadmap
The CHM (Mayotte Hospital Centre) will receive extensions including new operating theatres and enhanced maternity facilities. A hospital in Combani is planned for 2030. A midwifery school is scheduled to open between 2027 and 2028. On the security front, the government announces the dismantling of the Tsoundzou camp and the launch of "Kingia 2" operations in autumn.
Why it matters
Mayotte illustrates a structural challenge: turning emergency spending into sustainable development. The €4 billion committed represents a historic opportunity to equip the island with modern infrastructure — water, education, health, roads. But the risk of remaining an assistance economy is real unless private productive investment follows. For businesses in the region — particularly from Réunion and Mauritius — Mayotte represents a high-demand reconstruction market for the next five years.
