A STUDY OF RAINFALL FOR A BETTER OFFER OF VISITS ON 23 TOURIST SITES IN MADAGASCAR

Climate change

The rainfall is one of the climatic constraints that prevent tourist visits. This research focuses on 23 tourist sites in Madagascar that are popular for their fascinating biodiversity all over the world. They are relatively dispersed geographically in the island. This dispersion gives an overview of the national situation on green tourism. The aim of this work is to study the monthly rainfall of these 23 tourist sites in order to determine which are the least rainy and therefore the most accessible during each of the 12 months of the year. As such, we download the daily cumulative rain height data with a resolution of 0.125° x0.125° that have been provided by the ECMWF (European Centre for Medium-Range Weather Forecasts) for the period from 1979 to 2018. The result is a wide divergence in monthly rainfall conditions between the 23 tourist sites that can allow the development of green tourism throughout the year. The 23 tourist sites can still be visited in the same period of the year, but preferably from the least rainy month to the most rainy month, respectively from September, August, June, July, October, May, November, April, December, March, February and finally January.
