predict increased precipitation for the region. There is also a weaker link between climate change<br />
and droughts although there is a link to the El Nino Southern Oscillation (which in turn is linked to<br />
the low rainfall and dramatic spread of man-made fires in 1997 and 1998 in <strong>East</strong> <strong>Kalimantan</strong>).<br />
Agricultural yields could be significantly affected. Whereas many plant species are adapted<br />
to seasonal temperature variations, tropical species typically have a much lower tolerance for<br />
changes in temperature. The World Bank predicts that by 2050 Indonesia could see a 10 percent<br />
decrease in major crop yields due to temperature and rainfall changes. Finally, vector-borne<br />
diseases can increase, as dengue- and malaria-carrying mosquitoes expand their habitats with<br />
rising temperatures. <strong>East</strong> <strong>Kalimantan</strong> currently has a low incidence of malaria; its future moderate<br />
temperature increase compared to global averages and mountainous interior (higher altitudes with<br />
lower temperatures) could serve to moderate any expansion of the habitat of vector-borne diseases.<br />
<strong>East</strong> <strong>Kalimantan</strong> has extensive coral reefs, 86 percent of which are considered at risk. 22<br />
Indonesia’s longest continuous barrier reef system, the Sunda Barrier Reef, some 630 kilometers<br />
long, lies on the edge of the Sunda Shelf. It is largely unexplored despite its size and potential<br />
economic, social, and biological importance. <strong>East</strong> <strong>Kalimantan</strong>’s coral reefs are impacted by<br />
climate change in three ways. Coral bleaching occurs during abnormally high temperatures in the<br />
ocean and kills coral if they last more than two weeks. Coral drowning occurs when coral cannot<br />
grow fast enough to keep up with rising sea levels. Oceanic acidification occurs as more CO2 is<br />
dissolved in the ocean and disturbs coral growth.<br />
However, the threats of coastal flooding and inland flooding could pose a moderate risk<br />
to the province overall and potentially substantial localized risk to specific districts.<br />
<strong>East</strong> <strong>Kalimantan</strong> has 1,185 km of coastline, 368 small islands, and several coastal cities, such as<br />
Tarakan, Bontang, and Balikpapan. While <strong>East</strong> <strong>Kalimantan</strong> is relatively protected from event-driven<br />
(or storm-driven) coastal flooding, it is susceptible to coastal flooding from gradual rises in sea<br />

Coastal flooding<br />
and sea-level rise<br />
▪ <strong>East</strong> <strong>Kalimantan</strong> has a long<br />
coastline with major<br />
population centers<br />
▪ Susceptible to sea level rise<br />
▪ Strong relationship to climate<br />
change<br />
Storms<br />
▪ <strong>East</strong> <strong>Kalimantan</strong> is away from<br />
major tropical cyclone tracks, due<br />
to close proximity to the Equator<br />
(storms typically originate > 10 o )<br />

Inland flooding<br />
▪ El Niño Southern Oscillation<br />
and rainfall are strong<br />
drivers<br />
▪ Flooding in Samarinda<br />

Malaria and vectorborne<br />
diseases<br />
▪ Increasing temperature and<br />
rainfall are largely accepted<br />
as factors that increase<br />
malaria infection rates<br />
Agriculture yield<br />
change<br />
▪ Agriculture is 5% of GDP but<br />
important in rural areas<br />
▪ World Bank predicts yields<br />
could be negatively impacted<br />
by 10% in Indonesia due to<br />
climate change<br />
