et al., 2008). On the other hand, the projected greater<br />
potential evapotranspirati<strong>on</strong>, al<strong>on</strong>g with increasing<br />
populati<strong>on</strong> and the preference for groundwater<br />
rather than likely c<strong>on</strong>taminated surface water, will<br />
induce greater water demand in the dry seas<strong>on</strong>.<br />
In additi<strong>on</strong> to flood and drought, the sea level rise<br />
is observed as a c<strong>on</strong>sequence of global warming in<br />
the coastal z<strong>on</strong>e. The Initial Nati<strong>on</strong>al Communicati<strong>on</strong><br />
(Ministry of Envir<strong>on</strong>ment, 2002) projects that<br />
a sea level rise by <strong>on</strong>e meter would submerge<br />
approximately 56% of the low-lying city of Koh<br />
K<strong>on</strong>g. In additi<strong>on</strong>, <strong>on</strong>e-meter sea level rise would<br />
also submerge the total area of about 44km2<br />
permanently. Of the 44 km2 affected, 7.7% and 6.8%<br />
would be shrimp farm and grassland respectively.<br />
Hence, together with a changing climate, sea level<br />
rise would have negative impacts <strong>on</strong> socio-ec<strong>on</strong>omic<br />
activities of coastal communities<br />
such as fisheries, tourism and<br />
agriculture.<br />
Vulnerability and<br />
Adaptati<strong>on</strong> in the Water<br />
Sector<br />
The Nati<strong>on</strong>al Adaptati<strong>on</strong> Program<br />
of Acti<strong>on</strong> (NAPA) dem<strong>on</strong>strates the<br />
provinces that are highly affected<br />
by flooding and drought. The<br />
former are Kamp<strong>on</strong>g Cham, Prey<br />
Veng, Takeo, Kamp<strong>on</strong>g Thom and<br />
Battambang. The latter are Prey<br />
Veng, Battambang and Banteay<br />
Meanchey (Ministry of Envir<strong>on</strong>ment,<br />
2006). The level of vulnerability to<br />
flood and drought by province are<br />
shown in Figure 40 and Figure 41.<br />
and collaborative instituti<strong>on</strong>al set-up, including<br />
development of computer-based informati<strong>on</strong><br />
systems covering the results of surveys, assessments<br />
and observati<strong>on</strong>s in order to minimize the impact<br />
of sea level rise and establishment of cooperati<strong>on</strong><br />
frameworks, training, technology transfer in case of<br />
sea level rise (Ministry of Envir<strong>on</strong>ment, 2002).<br />
Resp<strong>on</strong>ding to some of the adaptati<strong>on</strong> opti<strong>on</strong>s<br />
recommended by the NAPA and Initial Nati<strong>on</strong>al<br />
Communicati<strong>on</strong>, the Ministry of Water Resources<br />
and Meteorology (MoWRAM) and the UNDP have<br />
implemented activities to sustain water supplies<br />
through drought management planning, early<br />
warning system for floodplain, enhanced irrigati<strong>on</strong><br />
technologies and instituti<strong>on</strong>al reforms <strong>on</strong> integrated<br />
water resource management (UNDP, 2009 cited<br />
in Solar, 2009). Moreover, in order to mitigate<br />

The NAPA also identifies several prioritised activities<br />
for climate change adaptati<strong>on</strong> in the water sector,<br />
including improvement of rainwater harvesting<br />
facilities at villages as well as the design of reservoirs<br />
and irrigati<strong>on</strong> channnels (Ministry of Envir<strong>on</strong>ment,<br />
2006). Specifically for the coastal z<strong>on</strong>es, the<br />
NAPA suggests several adaptati<strong>on</strong> opti<strong>on</strong>s such as<br />
rehabilitati<strong>on</strong> of multiple-use canals (Banteay Meas<br />
district, Kampot province) and coastal protecti<strong>on</strong><br />
infrastructure and community-based mangrove<br />
restorati<strong>on</strong> and agricultural soil c<strong>on</strong>servati<strong>on</strong> (Srae<br />
Ambel district, Koh K<strong>on</strong>g province).<br />
Prior to the NAPA, the adaptati<strong>on</strong> opti<strong>on</strong>s to resp<strong>on</strong>d<br />
to sea level rise <strong>on</strong> the coastal z<strong>on</strong>e were identified<br />
by the Initial Nati<strong>on</strong>al Communicati<strong>on</strong>. These are<br />
more focused <strong>on</strong> informati<strong>on</strong> and knowledge sharing<br />
vulnerability to natural disasters in coastal areas,<br />
integrated coastal management as well as ecosystembased<br />
approaches to fisheries have been carried<br />
out, including preventi<strong>on</strong> of saltwater intrusi<strong>on</strong><br />
to drinking water sources while maintaining fish<br />
protein sources (GEF, 2009 cited in Solar, 2009).<br />
However, the case study <strong>on</strong> drought management in<br />
Cambodia d<strong>on</strong>e by Kyoto Univeristy presents that<br />
dought management preparedness and resp<strong>on</strong>ses<br />
from government agencies does not seem to be<br />
well developed in the Svay Rieng province despite<br />
the regular occurance of drought in the area (MRC,<br />
2009d). Although planned opti<strong>on</strong>s for adapting to<br />
drought such as digging wells and providing pumps<br />
and better crop seeds are planned by government<br />
and some NGOs, no substantial invetiments in<br />
