Description

Following the Intergovernmental Panel on Climate Change (IPCC) report (2007) and Nicholls's Estimation (2006), Vietnam is one of the most endangered regions in the world under the effects of climate change such as ocean warming, sea level rise, typhoons, storm surges, and others.

Ca Mau province is located in the Mekong Delta of southern Vietnam where the poverty rates are estimated at 30-40% (MRC, September 2007). Ca Mau is the only province in Vietnam regulated by two conflicting tidal regimes namely the East Sea which is a large amplitude semidiurnal tide and the West Sea which is a diurnal tide of smaller amplitude. The complex saline-freshwater interaction coupled with the flat terrain and local geology open the region to the extremes (Vietnam Southern Institute for Water Resources Planning report - April 2008) as following:

* Flood season with heavy rains and high tide result in flooded cultivated land and strong winds, cyclones and lightning during heavy rains, lasting from May to December.

* Shortage of fresh water and devastating salinity intrusion in the dry season from the East Sea and West Sea.

* Acid sulphate soils (ASS) exist in some areas of the province, which can generate highly acidic waters in the first flushes of the rainy season.

* The province is susceptible to droughts and extreme dry periods, typically from December to April. Effects of droughts + more sunshine + higher temperatures + lack of fresh water + salinity intrusion + acid water generation cause forest fires which are made by dried trees and the carelessness of local people.

* Tropical low-pressure systems and storms often occur from the East Sea concomitant with heavy rain, and whirlwinds from May to December. During October to December, flooding, tidal waves and extreme downpours, can also inundate some dike routes, residential areas, escalate bank erosion in coastal protective forests, and pollute drainage.

* Cyclone and strong winds can cause huge waves detrimental to lives and properties in coastal areas.

All these phonomena will cause the land use vulnerability in Ca Mau province.

The general aim is to document, analyse and assess the vulnerability of land use/land cover in the coastal area under the context of climate change and accounting as well for other socio-economic and demographic pressure using Remote Sensing, Geographic Information System and models understanding such vulnerability essential to support the socio-economic development and contribute to sustainable environment protection.

The specific objectives includes determining the relationship between the changes in space and time of human activities (land cover / land use, agriculture, forest cover, etc), of natural hazards (erosion, sedimentation, floods, droughts, etc) and of climatic parameters (temperature, humidity, evaporation, etc) in the past. Based on analysis of trend and how they ... to climate change as well as on existing climate projections, models will be developed to analyse future land use trend. Proposing the appropriate solutions of diversity land use types of the study area in order to reduce or prevent the vulnerability under the context of climate change.
