||In the coastal Zone of Benin, the mangrove develops more in the sectors exchange and Westerner that Eastern, with a dominant species Rhizophoraracemosa. With the latter the species Avicenniagerminans, Conocarpus erectus and Lagunculariaracemosaare added which are non-existent in the Eastern sector. Indeed, the natural harmful anthropogenes activities and factors involved the regression of the surfaces of mangrove in the area of study. The aim of this research is to analyze the constraints which block the development of the mangrove in order to better define the approaches of their durable use. Collected data made with certain materials such as: the GPS, the topographic chart, the guides of observation, the guides of maintenance and the
investigations socio-anthropological (semi maintenance direct, x-ray group, interview) near the population target (fishing, salicultrices, etc.) allowed the use of model SEPO (Success, Echecs, Potentialités and Obstacles). This model puts forward successes, the failures, the potentialities and the obstacles related to the management of the mangrove to the Benin one. The results show
that various activities of afforestation carried out by certain institutions (ABE, DFRN, PPL, CeRPA, FAO, etc.) in load of the protection of the mangrove in the coastal Zone of Benign failed because of several constraints. To limit these last and to transform them into opportunities, an evaluation of the strategies of durable management of the mangrove makes it possible to better create an adequate framework of perennisation of the functions and services of this ecosystem.
