Abstract The objectives of this study were 1) to assess the
vulnerability of food security to climate change in the Hat Yai
District, Songkhla Province, 2) to devise means that might lead
to solving any perceived problems. The parameters of water
way, land use, roads, business zone, wetland, hospital site and
density of population of the selected Tambons as determined from
the Geographic Information System (GIS) by using the overlay
technique were assessed for their relevance to the study. From
this study the 7 areas of high risk included Tumbons: Khlong
U Taphao , Khu Tao, Khlong Hae, Hat Yai, Khuan Lang, Kho
Hong and Phatong. The vulnerability survey was supplemented
by interviewing people in the area using a questionnaire. It was
established that the key factors associated with climate change
that would affect food security were flood, long-term drought,
severe storms and rises in sea level. The highest risk area using
the Weighted Model was Tumbon Khlong Hae. In order to cope
with the climate change it will be necessary to obtain cooperation
from every relevant stakeholders i.e. residents, Governments and
their officers, educational institutions, research workers and food
companies. Budgets supports from National authorities must be
established together with the ability to integrate work practices,
enhance their ability to adapt and cope with the impact of climate
change
Keywords: vulnerability assessment, climate change, food
security outcomes
1. Introduction The global warming, at the present day, and the climate
change are the potential world problem which can have serious
impacts on economic social and environment. However, human
activities have accumulated the heat into Earth’s atmosphere
causing climate change. In general , many systems and groups
may face risk from mentioned factors and fragile to different
grievances depending on the capacity to adapt with the change
in the future which is different from area or society with difference
local physical and economic conditions. Thus, the solution of
climate change has involved in conducting of many stakeholders
[1-2]
The area of Hat Yai District, Songkhla Province,
is approximately 764 square meter or 478,093.92 Rai. From
survey the land use of Hat Yai in 2000 E.C. found that the land
for agriculture use is 61.7 % of all district area, the important
type food crops are rice, fruits and vegetable, just 5.26 % of
harvest gaining from Hat Yai agriculture. It is not sufficient to
meet the need of population in area so it is vital to depend on
the agricultural harvest from nearby provinces [3]
Hat Yai is one of the area have been predicted to
receive the impact from climate change because of Southwest
and Northeast wind especially the heavy rain in the area
causing big flood such as the flood disaster in the year 2000 ,
with estimated cost of damage more than 1,000 million Baht.
Subsequently , the canals were built by the royal project to halt
future flood, but the rainfall has increased in rainy season
causing flood every year. The data and monitoring situation
of the El Niño / La Niña phenomenon by the Meteorological
Department has predicted that during the winter of Thailand in
. 2010-2011 it will be very cold in many areas especially in the
north and northeast and the quantity of rain will also increase
especially in the South. Also in 2100 the averaged temperature
will rise by 1-2 degrees Celsius resulting in a further increase
in the amount of rain [4-5]
Thus, this study aims to make more understanding
of the impact of climate change to the fragile system of food
security and social impacts. It is very important and necessary to
find strategies and finding suitable measure to cope with climate
change.

2. Objectives 2.1 To study and assess the primary risk by risk
identification and to explain the risk characterization taking place
from climate change to food security in area of Hat Yai district,
Songkhla province.
2.2 To analyze the fragility of risk population in term
of food security which affect by climate change.
3. Methodology 3.1 Area boundary
It covers the area of Hat Yai District divided into 13
sub-districts as follows
1) Hat Yai 8) Tha Kham
2) Khuan Lang 9) Nam Noi
3) Khu Tao 10) Ban Phru
4) Kho Hong 11) Chalung
5) Khlong Hae 12) Phatong
6) Thung Yai 13) Khlong U Taphao
7) Thung Tam Sao
The GIS data such as water way, land use, road,
business zone, wetland, hospital site and density of population
were used as criteria to identify risk area.
3.2 Population boundary
Population means the whole household living in the
risk area in Hat Yai, Songkhla
3.2.1 The sample population
For random sampling, the quota sampling was
used.
3.3 The study tools
This research is participatory action one emphasizing
on community participation so it has to use various tools e.g. :
1) The secondary data were collected from reports
and documents from participating organizations.
2) The primary data which is the important data
for participatory action research , the data were collected
in community and community organization. The method to
obtain primary data has to use many processes such as survey,
interview, group discussion, focus group, participatory
observation and community stage etc.
3.4 Data analysis
The data of food security of the area was analyzed
by use 4 important components[6] i.e. availability, stability,
accessibility and utilization of food by communicating the risk
side to conduce policy determination easily to that people in the
community be able to understand and also adapted by involving
organizations.
4. Results 4.1 The overlay technique identified that the primary
risk areas are in 7 sub-districts i.e. Khlong U Taphao, Kho Hong,
Khlong Hae, Hat Yai, Khuan Lang, Kho Hong and Phatong shown
in figure 1

4.2 The vulnerable area predicted to take place in risk area of Hat Yai, Songkhla
The factors causing the vulnerability were flood, long time drought, severe storm and the higher sea water level which impact food security as follows,
4.2.1 Flood The impact to food security: The insufficiency of food: the impact level
may be high because Hat Yai has less cultivated
4.2 The vulnerable area predicted to take place in
risk area of Hat Yai, Songkhla
The factors causing the vulnerability were flood, long
time drought, severe storm and the higher sea water level which
impact food security as follows,
4.2.1 Flood
The impact to food security:
The insufficiency of food: the impact level may
be high because Hat Yai has less cultivated areas which may
result in shortage of food in flood time.
The accessibility of food: food price likely to be
increased , the income from agricultural sector will be decreased.
The accessibility to food is difficult for rural and poor people.
The food distribution will not be convenient because of flood and
the damaged roads.
55
The International Conference on Sustainable Community Development27-29 January 2011
The utilization of food: there is a risk from unsafe
food because of water pollution and disease. The Stability of
food: when food supply is not stable and fluctuating price, the
income of agricultural sector will fluctuate as well.
4.2.2 Long-term drought
The impact of food security:
There will be insufficient food: the cultivating food
crop and animal raising will be decreased because farmers will
unable to cultivate.
The accessibility of food: food price will likely be
increased , the income from agricultural sector will be decreased,
the shortage of popular food and high price.
The utilization of food: There are diseases
happening causing the body getting the less profit of food and
also there is changing nutrition because of the value of nutrition
change, the variety of food decreased and/or the nutritive value
decreased as well.
4.2.3 The severe storm
The impact of food security: the small scale
fishermen cannot earn a lot from fish resulting in insufficient food,
the income from selling aquatic animals decreasing and the
aquatic animals products are likely to be increased.
4.2.4 The increasing of sea level 0.5 meters
(Songkhla Lake)
The impact of food security: The area has been
lose because of the increasing of sea level and the lake water
will be more salinity. The water quality problem and less fresh
water resource will contribute to small scale fishermen, because
they will have less opportunities to fish especially in the Khu Tao
and Khlong Hae Sub-district.
4.3 The vulnerable of current agricultural security
in area of Hat Yai District, Songkhla Province
The vulnerable groups are farmers because they
have less production base and limited cultivating area, lacking
of motivation to remain be farmers and fishermen .
The vulnerable to food security happens because
of the limitation of production base resulting in food shortage,
since, the energy crop getting high price, some farmers switch
from cultivating food crops to cultivate energy crops. This will
result in less food reservation for emergency time. Capac i t y ,
farmers have limitation in cultivation because of high costs and
lack of area for cultivation.
4.4 The risk area and vulnerable group
From cluster analysis by group of Sub-district
according to the impact from climate change, it can be divided
into 3 groups from high to low impact respectively:
Group1 Khong Hae, Khu Tao, Khuan Lang and
Phatong
Group 2 Khong U taphao
Group 3 Hat Yai, Khor Hong
When analyzing to find the area by weighted Model
by using Multi-Criteria Evaluation: MCE, it found that the most
risk area is Khong Hae area.
Despite good water management such as The Royal
Project (Gamling Project) , the quantity of rain has exceeded
the capacity of all the drainage systems and caused severe
flooding in Hat Yai district in 2010 more than in any other past
year.
The Meteorological Department has predicted that the
phenomenon of La Niña in 2010 will have a big impact in the
southern region of Thailand and the quantity of rain will also
increase.
Normally, after the La Niña phenomenon during the
last part of the year it will be difficult for an immediate return
to El Niño because the high humidity it created will stay for at
least 1-2 years before El Niño will return . Thus, the preliminary
forecast for the first 5 years from now, is that Thailand will
gradually return to the El Niño condition. The drought in many
areas and severe storms than occur during the La Niña period
will have some impact on Thailand and then after 5 years from
the year 2016 – 2020 there will be a return to severe La Niña
and will be even more severe flooding than 2010. One should
remember that severe flooding occurred regularly in Hat Yai
about every 10 years.
Therefore, governments must as a priority integrate
the work of all agencies involved in water management such as
construction areas e.g. rivers , canals, irrigation systems, forest
preservation etc in preparation for The Royal Project (Gamling
Project), Buying back land from the public and leasing agricultural
land from agriculturists to cope with the impact from flooding.
5. Conclusion and recommendation 5.1 Conclusion
The factors effecting the vulnerable to climate change
that have impact to food security are flood, long time severe
drought, strong storm and the higher sea water level.
The vulnerable groups/ stakeholders are farmers, low
income people, patients, elders and children.
5.2 Recommendation
5.2.1 The governments must as a priority integrate
the work of all agencies involved in water management such as
construction areas e.g. rivers , canals, irrigation systems, forest

preservation etc in preparation for The Royal Project (Gamling
Project), Buying back land from the public and leasing agricultural
land from agriculturists to cope with the impact from flooding.
5.2.2 Supporting the natural and environmental
awareness in the aspect of ecosystem by participating of people,
local governments and private sector from the level of national
policy, organization and local government including integration
of budget, operation and knowledge.
5.2.3 Determine impact of climate change by
promoting the research and human resource development, with
clear goals, and able to bring to negotiation and prepare to cope
with climate change.
5.2.4 Emphasis on more research study
concerning to natural and environmental management in all level
and widely passing on the knowledge to action and continuously
implementing plan
5.2.5 Supporting sustainable production and
consumption by efficiently using natural resources. Pay more
attention to environmental impact, e.g. using the measures
for Life Cycle Assessment (LCA) to show the efficiency of
worthwhile resources use and taking the resource to process
for sale promotion, creating value for products by dividing the
resource of each Sub-district in value addition to product brand
of each Sub-district
