Dozens of climate change activists from international organizations and local organizations in Cambodia on Wednesday gathered at Wat Phnom in front of the Big Clock as a part of the global campaign against climate change and to raise awareness of climate change in Cambodia.

The climate change activists held banners and shouted that " time is running out" and "they must act now".

Cambodia is one of the most vulnerable countries to climate change impacts due to its low capacity and limited resources to address climate change, the press release from the event said.

At the same time, the activists also demanded for a fair climate deal for Cambodia and developing countries ahead of global change negotiations in December in Copenhagen, Denmark.

Seang Soleak, spokesman for Oxfam international, told reporters that agricultural countries like Cambodia is easy to be affected from the climate change because the agricultural sector depends on rain.

"Therefore when the rain falls on irregular time, the rice product will decrease and people will face food insecurity and its price will be higher and higher," he noted. "We have to join together to prevent climate change," he said, adding that climate change is threatening social and economic development and the effort to help reduce poverty in the country.

Data from the past five years indicates that more than 70 percent of rice production loss in Cambodia was primarily due to flooding while drought was responsible for about 20 percent of the loss.

Cambodian Prime Minister Hun Sen said on Monday in his opening remarks of the first national climate change forum here that the developed countries need to help poor countries through transferring new technology.

Oxfam international in Cambodia also demanded developed countries, in its press release, to meet their historical responsibility for climate change and to help channel resources to areas that are feeling immediate impacts for climate change like Cambodia.
