Laguna de Bay Institutional Strengthening and Community Participation (LISCOP)

MANILA, APRIL 12, 2011—The World Bank’s Board of Executive Directors approved today a US$ 10 million loan for the scaling up of priority environmental subprojects implemented by the Local Government Units (LGUs) designed to improve the environmental quality of the Laguna de Bay and its watershed.Specifically, the support will finance additional environmental subprojects including solid waste management facilities (material recovery facility, composting facility, and sanitary landfill), eco-tourism, wastewater treatment, and local drainage and flood control along the 24 river systems draining into Laguna de Bay, thus reducing pollution in the lake and preventing the degradation of its watershed.
