This scenario simulates a doubling of pineapple areas at the expense of sugar cane areas. Indeed, the diversification of sugar cane towards pineapple cultivation is a change in use observed for several years in Reunion Island. This scenario, is based on the same hypothesis of 'Market garden' scenario, this scnario models a 25% change in cane areas into market gardening, pineapple and arboriculture areas, distributed equally. Scenario simulates a 15% increase in grassland areas linked to fodder production in the Lower Mainland at the expense of sugar cane areas. This scenario is based on the objective of increasing the number of animals in the sectors for which, in the absence of improved yields, fodder requirements will have to be met by increasing the area of hay meadows (Leleux, 2016). Scenario simulates the closure of the Gol plant in the south of the island. The areas previously used as cane are transformed into 40% grassland, 40% market gardening, 10% pineapple and 10% arboriculture. Models a monoculture cane system in Reunion Island; all the surfaces are therefore transformed into sugar cane. Scenario models an increase in the area under market gardening in order to achieve self-sufficiency in market gardening products in the next 20 years, i.e. by 2040; the increase in the area under market gardening being to the detriment of that under sugar cane. Assuming that local fruit and vegetables supply 70% of the fresh market, a change of 7.3% of the cane areas to marketable areas should make it possible to achieve the 100% supply target for the fresh market.
