Landscapes of mangrove forests and littoral dynamics in the South Viêt-Nam

Abstract

French colonization (1860–1945), Indochina (1945–1954) and Viet-Nam’s Wars (1961–1975) illustrate during nearly one century, the use of the littoral at “strategic” ends (commercial and military). The discovery of the coasts of Cochinchina allowed the conquest of new grounds and the progressive development of the primarily alluvial plains. The mangrove forests in the South Viet-Nam are the witnesses of a destruction then of a cicatrization of the landscapes. A progressive dynamics and a reconquest of formerly bombarded lands, intensely defoliated, set up themselves. We can speak about “rebirth” because it is possible to see, rebuild this dynamics as from one moment “zero” (war) and to compare with the evolution of the current vegetable formations, using Remote Sensing and Geographical Information Systems (GIS). These devasted landscapes were transformed into a success, by positive effect of the rehabilitation of the coasts. Finally, the possible reconquest of the littoral by the plants is due to the great capacity of nature to be regenerated.
