Joko mentioned the moratorium in his speech at an environmental event to celebrate International Forest Day on Karya Island, in Jakarta's Thousand Islands district, on Thursday (14/04).
"Prepare for a moratorium on palm; prepare for a moratorium on mining," the president said.
He added that the current number of palm-oil plantations in the country were already sufficient, as farmers could still boost their production capacity by using the available resources, such as better seeds and technology.
Joko said he would also not allow any more licenses for mining companies to expand their operations in these areas.
"No more of the mining concessions breaching into conservational forests," the president said.
Moreover, Joko emphasized that all stakeholders should preserve Indonesia's biodiversity, as the country is famous for its natural resources and its forests, dubbed "the lungs of the world."
