Vulnerability and AdaptationVulnerability and Adaptation• As a tropical country, Thailand is highly, vulnerable to climate
change in five major areas – Agriculture – Forest – water resources– Coastal – Health
• V&A is the most disadvantage area of work in climate change• Capacity building on research and and development is urgentl

the issues• Need immediate attention regionally and globally.

Kanae et.al., (2001). Significant decrease in precipitation over Thailand were detected only in September.
The magnitude of the mean decrease over the whole deforested area was relatively 7% change and the local maximum decrease was 29% relative change.
It is explained that the monsoon westerlies which are normally predominant external force influencing this regional climate disappear in September when the maximum rainfall is typically occurred.

Is monsoon rainfall decreasing? -Is monsoon rainfall decreasing? -Impact of deforestation in Thailand on water Impact of deforestation in Thailand on water cyclecycle
The rainfall in the whole of Thailand in the late monsoon season (September) shows a remark
able decreasing trend since 1950’s. This decrease of rainfall may, at least partly, be attributed to
the change of surface water balance induced by change of the surface vegetation condition, i.e., the
deforestation over the whole of the country as shown in Fig.1. The recent model study (Kanae et al.,
2001) has suggested that the decreasing trend of rainfall in September may be related at least partl
y to the recent deforestation in Thailand.
That is, the deforestation over a wide region in the plain area of Thailand is likely to induce red
uction of surface roughness and evaporation efficiency, and increase of albedo(reflected short wave
radiation), which result in increase of sensible heating and decrease of evaporation. This change of s
urface heat balance in turn affect atmospheric stability to decrease cumulus convection and rainfall.
However, this effect of deforestation to decrease rainfall is noticeable only in September, when the s
outhwest monsoon current has become weak. In July and August, when the monsoon current is still
strong, the change of land surface condition by deforestation tends to change distribution of rainfall
, rather than to decrease the overall rainfall amount over the deforested area

Role of large-scale vegetation and land use on water cycle and climate in monsoon Asia
Prof Tetsuzo YasunariFrontier Research System for Global Change (FRSGC)
and Institute of Geoscience, University of Tsukuba
The results of the experiment on the impact of Indochina deforestation on the East-Asian summer monsoon by Sen et.al (2003) indicate that deforestation in the peninsula has not only local but also far-reaching effects on the East Asia summer monsoon. Locally, the effect could be described as increases in wind speed and Temperature, and decrease in water vapor mixing ratio from surface up to about 850 mb.
Furthermore, the deforestation tends to enhance the rising motions, and hence, tends to reduce surface pressure and geopotential height up to about 850 mb over the deforested area. The local landscape changes tend to increase rainfall on the downwind side and decrease it on the upwind side.

Recent changes in number of foggy days in Thailand, especially in the North have been observed by Nomoto (1999) and Nomoto (2003). The number of foggy days has been decreasing at most stations, especially Chiang Rai (CR), Phrea (Ph) and Nan (N)
provinces. Assuming that the trends in changes are linear, the rate of decrease reached 1.42 days/yr at CR, 2.01 days/yr at Ph and 1.97
days/yr at N respectively. The numbers at Mae Hong Son and Mae Sariang have not decreased continuously, but have fluctuated widely
throughout the period (1951-1995).

• In addition to island nations, low-lying coastal countries are threatened by rising sea level.
• A 1 meter rise in sea level would inundate half of Bangladesh’s rice land. Bangladeshis would be forced to migrate by the millions.
• Other rice growing lowlands which would be flooded include those of Viet Nam, China, India and ThailandThailand. Millions of climate refugees could be created by sea level rise in the Philippines, Indonesia and Egypt.

Sea Level Trend in Gulf of Thailand Using Tide Gauge Data
สมมาตร เนียมนี�ล และ อ�ที่ธิ� ตุร�สิ�ร�สิ�ตุยวิงศSommart Niemnil and Itthi Trisirisatayawong
ABSTRACT• Sea level change is an index of climate change especially the global warming. Global sea level is rising at 1.8 mm/yr (IPCC,2007),
but few studies have been conducted regarding local sea level change and there is virtually no systematic study in the Gulf of Thailand. The objective of this research is to determine the rate of sea level change in the Gulf of Thailand using annual average sea-level data from 3 tide gauge stations of Hydrographic Department, Royal Thai Navy namely Sattahip station in Chonburi province, Ko Lak station in Prachuap Khiri Khan province and Ko Mattaphon station in Chumporn province and one station from Port Authority of Thailand namely KoSichang in Chonburi province.
• The results shows no agreements among the rates determined from different stations. Analysis of data of Sattahip station, Ko Mattaphon and Ko Sichang yield the rising rate of 0.22, 0.51 and 0.81 mm/yr respectively whereas data from Ko Lak station, Prachuap Khiri Khan gives a falling rate of 0.52 mm/yr.
• The conflicted results indicate the need of further investigation of local factors before actual rate of sea level change in the Gulf of Thailand could be determined.

Results from the models:Results from the models:– Thailand has approximately 2940km of coastline, much of
which contains important economic activities such as shrimp farming and rice farming. The study considered the potential impact of a 0.5 m and 1 m rise of sea levels in the Suratthani Province in southern Thailand.
– This region is characterised by a sand dune line which may mark an ancient shoreline and has a consistent elevation about 1m above present sea level. It was therefore used as an indicative boundary to the area potentially affected by a 1m sea-level rise.
– The suggestion is that 7400 ha (37 percent) of the study area would be affected by inundation under a 1 m sea-level rise. About 4200 ha of productive agricultural land and large numbers of shrimp ponds would be lost.

A climate model suggests that chopping down the Earth's trees would help
fight global warmingGlobal warming :A new tree line Apr 12th 2007 From The Economist print edition
……… Dr Bala of the Lawrence Livermore National Laboratory, in California, and his colleagues has found, rather counter-intuitively(ความร��ส�กที่�เก�ดขึ้��นีอย�างตรงก�นีขึ้�าม), that removing all of the world's trees might actually cool the planet down. Conversely, adding trees everywhere
might warm it up.
http://www.economist.com/science/displaystory.cfm?story_id=8998216
…… When Dr Bala ordered global clearcutting, the Integrated Climate and Carbon Model calculated that the atmosphere's carbon-dioxide levels would roughly double by 2100. This is a much greater increase than happens in a business-as-usual simulation, but it would, paradoxically, make for a colder planet. That is because brighter high latitudes would reflect more sunlight in winter, cooling the local environment by as much as 6°C. ………….

Thai temple fights off encroaching tide as world sea levels rise"
• March 31, 2008KHUN SAMUT CHINI - The deserted Khun Samut temple, the only building left in a Thai village, has been eroded by waves as time goes by . The encroaching tide has sent all the villagers fleeing inland.
• Over 30 years, the sea around Khun Samut Chin village has engulfed more than one kilometre (0.6 miles ) of land, World Bank figures show, mostly because fishermen have cut down mangrove forests -- the Earths natural sea barrier.
http://www.manager.co.th/Home/ViewNews.aspx?NewsID=9510000038286"
• Tourism development, sand mining and damming rivers upstream have also taken their toll in an area naturally prone to coastal erosion. • The community have realised their errors and are trying to replant the mangroves, but the situation may soon be out of their hands as global warming sends sea levels rising and powerful storms lashing the coast. • The process has been occurring over some time and accelerating with land use changes and local human activity, says Jitendra Shah, the World Banks environmental coordinator in Thailand.
