Landscape ecological planning based on change analysis: A case study of mangove restoration in Phu Long – Gia Luan area, Cat Ba Archipelago

Mangroves play an important role in coastal zones in many aspects e.g. extremely essential habitats for many species, coastlines protection from natural hazards, and so on. However, in Vietnam, like in other developing countries, these mangrove areas have been destroyed and encroached as a consequen...
