Key PAPSs in the 2015 budget that contribute to WS objectives DPWH’s climate expenditures are mainly concentrated in the Flood Risk Management and Resiliency Program, which accounts for 97% of WS expenditures (PHP 67.7 billion, compared to PHP 45.9 billion in FY 2015). This Program has two key strategies: (1) Implementing a river basin approach for effective flood control, and (2) designing and constructing disaster-resilient public infrastructure facilities. In support of these two strategies, DPWH supported several PAPs, including: Construction/Rehabilitation of Flood Mitigation Structures along Major River Basins (DPWH, PHP 3.4 billion, compared to PHP 3 billion in FY 2015): In FY2016, DPWH set a target of 970 projects for the construction and maintenance of flood mitigation structures and drainage and 120 projects for the construction and rehabilitation of 120 flood mitigation structures. This program uses a river basin approach and focuses on designing and constructing disasterresilient public infrastructure facilities for effective flood control. However, only 8% of DPWH’s flood management services expenditure goes to major and principal basins. Pilot spatial analysis on the Flood Mitigation programs of DPWH is completed for FY16 (Refer to Chapter VII), • • Flood Forecasting and Hydro m eteorological Services in Major River Basins (DOST, PHP 0.06 billion, compared to PHP 0.16 billion in FY 2015): The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) of DOST provides crucial services of generating flood forecast and information important to climate response, especially for early warning, along major and principal river basins. The allocation to support these activities is 62% smaller than the FY 2015 GAA, and has been moved from expenditures tagged as KCD to WS. In addition, the DPWH’s Construction of Rainwater Collection System s (RCS) constitutes 1% of the total climate budget request for WS, in line with DPWH’s responsibility to lead in implementing Republic Act No 6716 (Rainwater Catchment Law) for the installation of RCS in public schools and other state facilities. A total of 513 rainwater collection systems have been installed through 2013. To expand the program, DPWH’s approved climate expenditure is 600% more than the program’s FY 2015 GAA approved expenditure. Finally, evaluation, integration and coordination of water resources plans and program s at specific local sites are being im plem ented by the DENR–National Water Resources Board (NWRB), which allocated PHP 0.03 billion. Although this represents an increase of 60% from the 2015, it accounts for less than 1% of the DENR’s climate budget for 2016.   14
