The airport of Mayotte is the entry/exit point of the island for people. Without an innovative solution, SEAM would have no choice but to reduce the runway length by 180 m, drastically limiting the capacity of Mayotte airport. Only small aircraft could be accommodated with a significant negative impact on airport activity and employment, as well as on the accessibility and development of the island: tourism, freight, mobility of individuals, in particular allowing the rise in competence of the marshland... The project, with due regard for the environment, is to retain its technical capacity to accommodate aircraft at Mayotte airport. Stopping beds or EMAS help to achieve this objective and in particular: >> not to block the economic development of the island by providing it with an increasingly convenient service to the metropolis and the southern area of the Indian Ocean; >> to continue the growth of air traffic towards the expected target of 600 000 passengers per year in 2026 (correlated air freight) and not to undermine the employment potential of the aviation sector; >> avoid the sharp increase in the carbon footprint of connections with the metropolis if they were to be carried out again by Réunion (+ 1.5 million tonnes of carbon over 30 years); >> not to increase the airport’s pressure on its environment (no expropriations to the north of the runway and no work on the lagoon to the south).
