Vietnam coastal cities and potential impacts of sea level rise

Hơn hai mươi thành phố ven biển Việt Nam với dân số 10.000.000 trực tiếp chịu tác động của mức nước biển dâng cao. Vì đây là một sự kiện khởi phát rất chậm, nguy cơ nhận thức của xã hội là yếu. Trong bối cảnh này, giấy khám phá một loạt các vấn đề liên quan đến thảm họa dễ bị tổn thương và xác định các ưu tiên cho phòng chống thiên tai và chuẩn bị cho cuộc sống với nguy cơ. | Vietnam coastal cities and potential impacts of sea level rise Dr. Pham Si Liem Institute for Urban Studies Infrastructure Development.Hanoi-Vietnam Email tonghoixdvn@yahoo. com. vn ABSTRACT More than twenty Vietnam coastal cities with a population of ten million are directly subjected to the impacts of a rising sea level. As this is a very slow-onset event the risk perception of the society is weak. In this context the paper explores a range of issues related to disaster vulnerability and identifies priorities for disaster prevention and preparedness for living with risk. KEY WORDS Sea level rise Urban vulnerability Adaptation policy Information gathering and exchange Introduction Sea level rise is a complex phenomenon related to the global climate change. Although the mean increases in sea level All abovementioned major impacts of sea level rise once occurred will engender huge negative effects to the development of Vietnam in the future. rise associated with the Intergovernmental Panel on Climate s Change IPCC non mitigation scenarios are modest-ranging from 0.2 to 0.5 meters during this century future sea level rise is not expected to be globally uniform. Some regions including South-East Asia show a sea level rise substantially more than the global average. This paper focuses on the potential impacts of sea level rise on Vietnam coastal cities and explores the concept of a desirable urban adaptation policy required to cope with this profound and durable disaster.
