  • Climate Change Impacts and Responses in the Philippines: Water Resources
    CLIMATE RESEARCH Vol. 12: 77–84, 1999 Published August 27 Clim Res Climate change impacts and responses in the Philippines: water resources Aida M. Jose, Nathaniel A. Cruz* Climatology and Agrometeorology Branch (CAB), Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), 1424 Quezon Ave., Quezon City, Philippines ABSTRACT: The Philippines, like many of the world’s poor countries, will be among the most vulnera- ble to the impacts of climate change because of its limited resources. As shown by previous studies, occurrences of extreme climatic events like droughts and floods have serious negative implications for major water reservoirs in the country. A preliminary and limited assessment of the country’s water resources was undertaken through the application of general circulation model (GCM) results and cli- mate change scenarios that incorporate incremental changes in temperature and rainfall and the use of a hydrological model to simulate the future runoff-rainfall relationship. Results showed that changes in rainfall and temperature in the future will be critical to future inflow in the Angat reservoir and Lake Lanao, with rainfall variability having a greater impact than temperature variability. In the Angat reser- voir, runoff is likely to decrease in the future and be insufficient to meet future demands for water. Lake Lanao is also expected to have a decrease in runoff in the future. With the expected vulnerability of the country’s water resources to global warming, possible measures to cope with future problems facing the country’s water resources are identified. KEY WORDS: Water resources · GCMs · CCCM · UKMO · GFDL · WatBal · Angat reservoir · Lake Lanao 1.

  • Angat Water Transmission Improvement Project Metro Manila, the Philippines
    Angat Water Transmission Improvement Project Metro Manila, The Philippines i Summary Metro Manila also called the National Capital Region (NCR) is situated in the south eastern part of the Philippines. Serving as the main economic culture and educational center, the region is a densely populated metropolitan area. The Angat Water Transmission Improvement Project (AWTIP) was designed to ensure secured and sufficient raw water supply to meet the current and future demands of the rapidly growing population of Metro Manila. The project focuses on the construction of a new 6.3 km tunnel (no. 4), intake structures at the Ipo dam and connecting structures of the transition basins, new aqueduct (no. 6)., rehabilitating and retrofitting of existing tunnels and aqueducts. The project is expected to restore the water transmission capacity of the Angat transmission system which currently operates about the 30% below its design capacity. Given the rapidly growing population of a highly populated Metro Manila, the project would ensure that a maximum capacity of 4.65 million m3/d of raw water is transmitted from the Angat dam at maximum efficiency. In addition, the execution of the project is expected to build the technical capacity of the staffs of the Metropolitan Waterworks and Sewerage System (MWSS), who are the primary administrators of the project. The project features social and economic aspects that are targeted towards improving the livelihood and health conditions of source community’s programs and indigenous people. The project also has in place environmental safeguards that aim at reducing and mitigating direct and indirect impacts on the biotic and abiotic parts of the environment.

The thesis may not be reproduced elsewhere without the permission of the Author. The Use GIS and Remote Sensing in the Assessment of Magat Watershed in the Philippines A thesis presented in partial fulfilment of the requirements for the degree of Master of Environmental Management Massey University, Turitea Campus, Palmerston North, New Zealand Emerson Tattao 2010 Abstract The Philippine watersheds are continually being degraded— thus threatening the supply of water in the country. The government has recognised the need for effective monitoring and management to avert the declining condition of these watersheds. This study explores the applications of remote sensing and Geographical Information Systems (GIS), in the collection of information and analysis of data, in order to support the development of effective critical watershed management strategies. Remote sensing was used to identify and classify the land cover in the study area. Both supervised and unsupervised methods were employed to establish the most appropriate technique in watershed land cover classification. GIS technology was utilised for the analysis of the land cover data and soil erosion modelling. The watershed boundary was delineated from a digital elevation model, using the hydrological tools in GIS. The watershed classification revealed a high percentage of grassland and increasing agricultural land use, in the study area. The soil erosion modelling showed an extremely high erosion risk in the bare lands and a high erosion risk in the agriculture areas.

  • Cagayan Riverine Zone Development Framework Plan 2005—2030
    Cagayan Riverine Zone Development Framework Plan 2005—2030 Regional Development Council 02 Tuguegarao City Message The adoption of the Cagayan Riverine Zone Development Framework Plan (CRZDFP) 2005-2030, is a step closer to our desire to harmonize and sustainably maximize the multiple uses of the Cagayan River as identified in the Regional Physical Framework Plan (RPFP) 2005-2030. A greater challenge is the implementation of the document which requires a deeper commitment in the preservation of the integrity of our environment while allowing the development of the River and its environs. The formulation of the document involved the wide participation of concerned agencies and with extensive consultation the local government units and the civil society, prior to its adoption and approval by the Regional Development Council. The inputs and proposals from the consultations have enriched this document as our convergence framework for the sustainable development of the Cagayan Riverine Zone. The document will provide the policy framework to synchronize efforts in addressing issues and problems to accelerate the sustainable development in the Riverine Zone and realize its full development potential. The Plan should also provide the overall direction for programs and projects in the Development Plans of the Provinces, Cities and Municipalities in the region. Let us therefore, purposively use this Plan to guide the utilization and management of water and land resources along the Cagayan River. I appreciate the importance of crafting a good plan and give higher degree of credence to ensuring its successful implementation. This is the greatest challenge for the Local Government Units and to other stakeholders of the Cagayan River’s development.
