Second biggest contributor to the gross value added of Agriculture, Fishing, and Forestry in the country since 2013. • Need to have a coherent information to allow policymakers and program implementers understand how the natural resources are being used as inputs to the economic activities of the region. Allows decision makers to assess whether the region is gearing towards sustainable development. Developing the Water Flow Accounts of Region X Solid Responsive AUTHORITY World-clas 2#315TH NATIONAL CONVENTION ON STATISTICS 03-05 OCTOBER 2022 Organized by the Philippine Statistical System Spearheaded by the Philippine Statistics Authority PHILIPPINE STAT STATISTICS What is Physical Flow Accounting? • The physical flow accounts for water resources describe the flows of water to and from the environment and the economy. The accounts cover the entire process of water supply and use - from the initial abstraction of water from the environment into the economy, to the flows within the economy done by the different industries and households, and finally, return flows from the economy back to the environment.

Responsive Framework Sections Return flows of wastewater to the environment Evaporation, transpiration and water incorporated into products Description water that is returned to the environment and is recorded as being supplied to the environment. flows of evaporation are recorded when water is distributed between economic units after abstraction. Transpiration of water occurs when soil water is absorbed by cultivated plants as they grow and is subsequently released to the atmosphere. Amount of water incorporated into products are shown as supplied by the relevant industry (e.g., water is used in the manufacture of beverages).

The estimation of water abstraction is limited to the assumption that the NWRB permittees are abstracting water in full capacity. In addition, abstraction of water from protected areas are not included. Volume of industrial wastewater was estimated Agricultural wastewater was not taken into account due to data unavailability. There is no data available on the actual amount of captured rainwater. It has been a wide practice on the use of rainwater as inputs to economic activities (e.g. sprinkler systems, toilet flushing, etc.) • A concern was raised in one of the technical sessions on the parameter used for the per capita daily water requirement of Filipino individuals (54 L per day) which is still based on a 1999 study. There could be changes on the water requirement especially with the additional hygiene requirements of the pandemic.

Discussions may focus on the processing of submitted reports for access by data users such as the compilers of Water Flow Accounts. Coordinate with EMB Regional Office X for the generation of actual water used, volume of wastewater, and volume of treated wastewater by industry based on the submitted Self-Monitoring Reports of the industries. Further consultation with DENR on the generation of data on abstracted water from protected areas. During the conduct of this study, DENR is still establishing the issuance of permits for the users of water in protected areas.

May consider an updated parameter on per capita daily water requirement of individual. The physical flow accounts for water resources will be updated in 2023 to include additional data and updated parameters for the period 2018-2022. Supplement the physical flow accounts with the monetary flow accounts.
