JAKARTA, Sept. 25-- Indonesian President Susilo Bambang Yudhoyono said that Indonesia has been seeing enormous contribution from implementation of Reducing Emission from Deforestation and Degradation (REDD+) to reduce emission and impacts of greenhouse effect, a statement released Indonesian foreign affairs ministry said on Thursday.

"REDD+ is a very essential mechanism should we want to see increase of average earth temperature below 2 degrees by the end of the century," President Yudhoyono said in his remarks to open Indonesia's REDD+ Forum in New York, the United States on Wednesday.

He added that successful implementation of REDD+ needs several changes, which include a change in the way to exploit the forest resource, and that of social and environment condition in the field.

"The third is that implementation of REDD+ must involve stakeholders that consisted of non-government organizations (NGOs), private sector, local people and government. Besides that, government's role as the regulator is very crucial to address the implementation," the president said in the statement.

REDD+ is a mechanism for countries endowed with vast areas of primary forests initiated in 2005 to tackle climate change impacts, reduce carbon emission, preserve the forest and exploit the forest resource with sustainable and renewable ways.

The president said that 20 percent of world's greenhouse effect emission were resulted from unwise forest exploitation. Maximizing implementation of REDD+ would help global efforts to tackle impacts of climate change.

President Yudhoyono said that Indonesia has saved 53 million hectares of forest areas after implementing moratorium on exploitation of forest and peatland since 2011 to 2013. Due to its success, government continued the implementation for another two years.

"At the same time Indonesia is also facing challenges from the increasing of population, need of energy and food. All of those challenges give significant pressures to the nation's resources. But with good distribution of responsibilities and partnership, no challenge can not be solved," the president said.

Indonesia has signed agreement on 1 billion U.S. dollars assistance fund from Norway to finance its REDD+ efforts.

At the 2009 G20 summit in Pittsburgh, the United States, President Yudhoyono pledged to reduce emission by 26 percent with the country's own efforts and 41 percent with foreign assistance by 2020.
