The Philippines is one of the 17 megadiverse countries in the world, and also one of the top nickel ore exporters worldwide. With the high global demand for nickel due to its vital role in modern infrastructure and technology, the Philippines also faces a tantamount environmental risk. Although several mining operations have been suspended by the government, there still is a great uncertainty regarding the extent of the environmental problems.
By identifying where sediments come from and how they settle down in the river systems, we will be able to define the contribution of mining activities to the problem and assess suitable measures to reduce siltation in lower-lying areas. In addition to improving agricultural productivity, this research also hopes to promote responsible mining practices, both yielding positive economic impacts at the local and national levels.
