Abstract: Les surfaces couvertes en vue de produire des especes vegetales (maralcheres et hortlcoles) sont en augmentation aux Antilles-Guyane. On asslste a une adoption de techniques, materiels et equipements tres divers et varies. Partant d'une constatation des atouts et contraintes qu'offre le climat tropical de basse altitude, l'auteur analyse graduellement les avantages mais aussi les exigences lnduites par des niveaux de technologle croissante : Passage de l'agriculture saisonniere de plein champs a la culture continue sous abri serre, puis evolution vers les cultures sans sol dites "hydroponiques". A aucun moment le producteur ne doit negliger dans son evolution technique de se resituer dans le contexte conmercial. Seule la cons iderat ion rea liste de tous les parametres evoques permettra un developpement durable des cultures abritees sans sol en zone tropicale humide. -- Areas for protected crop production are increasing in the French West Indies and Guyana. Techniques, materials and equipment used are large and divers ifi ed. By estab 1ish ing the assets and constra i nts associated with the low altitude, humid tropical climate, the author has derived the advantages and requirements resulting from these increased levels of techno logy: Passage from seasona 1 outdoor agriculture to continuous production in greenhouse and progression to soilless cultivation or "hydroponics". At all stages in this technical evolution the grower must take into account the changing financial and conmercial context. Only when all these aspects are fully considered, will the development of protected soilless culture in humid tropics become effective and durable.
