4 Confluence of Problems Denuded Watersheds Conflicting Water Uses Flooding Hazard Lack of Economic Opportunities Vulnerable Communities Deteriorating Water Quality By 2020, Laguna de Bay Basin is a sustainable multiuse and high value resource, and an engine for ecologically sensitive development. WATERSHED SHORELAND Rehabilitated and protected as water resources, and sustainable source of economic assets Protected buffer zone Secure, productive, environmentally conscious, empowered lakeshore community stakeholders Healthy ecosystem to sustain life LAKE & RIVERS and host complementary uses Integrated Lake Basin Authority co management by stakeholders, financially independent 4

5 LAKE BASIN STRATEGIC POLICY AREAS Promote integrated lake basin management Pursue interventions in areas needing remediation, proactive conservation, and areas for demonstrating lakesensitive developments Build on existing gains of earlier interventions Define trans boundary resources for stronger comanagement and citizenbased approaches Protection/ Conservation Rehabilitation Lake Sensitive Development Land Use Changes in Laguna de Bay Basin 5

6 DENUDED SUB WATERSHEDS FLOOD HAZARD 6

7 SCOPE OF SRATEGIC POLICY AREAS Protection/ Conservation Rehabilitation Lake sensitive Development Areas declared for protection by existing laws and needing proactive conservation measures. These cover: Remaining forest cover (reserved and production forests) Central bay (including fish sanctuary) Buffer zones of water bodies Areas needing special and immediate rehabilitation and restoration. These cover: Denuded watersheds Critical river tributaries Shoreland and salvage zone (flooded areas) West bay Areas where sustainable economic support is needed and where LLDA can demonstrate its strategic economic investments. These cover: South and East bays Shoreland Green Development Zone Other Lands suitable for mixed uses MANAGEMENT STRATEGIES 1. Intensify protection of remaining lake basin resources to prevent degradation 2. Improve and protect lake water quality through an integrated network of environmental measures 3. Abate denudation and promote ecologically sensitive land resource uses 4. Mitigate impacts of flooding and climate induced hazards through sustainable infrastructure and non infrastructure interventions 5. Reduce vulnerability of the lakeshore communities and model sustainable settlements 6. Rationalize lake water uses through prudent demand supply management 7. Harness LdB water and land resources as sustainable economic assets through co management and citizen based strategies 7

12 Integrated Watershed Management Program Strategies and Approaches Designation of 24 sub-basins into sub-wqmas through LLDA Board Resolution Creation of Watershed Management Councils Integrated t Watershed Planning and Development Water Quality/Pollution Groundwater Scarcity/Depletion Flooding Watershed Degradation Implementation of planned interventions Pilot program implementation in the Santa Rosa and Marikina Sub-basins Reforestation in support of National Greening Program (Executive Order No. 26) Laguna de Bay therefore cannot be subjected to fragmented concepts of management policies i where lakeshore local government units exercise dominion over specific portions of the lake water. The garbage thrown or sewage discharged into the lake, abstraction of water from the lake or construction of fish pens by enclosing certain areas thereat, affect not only the specific portion but the entire 900 km 2 of lake waters. The implementation of a cohesive and integrated lake water resource management policy, therefore, is necessary to conserve, protect and sustainably develop Laguna de Bay. 12
