Introduction

The Performance of Agriculture presents the accomplishments of agriculture during a particular reference period. The performance is measured in terms of value of production at constant prices and at current prices. It focuses on the measurement of the whole agriculture and its sub-commodity groups (crops, livestock, poultry and fisheries) and commodities. These serve as inputs in the estimation of Gross Value Added (GVA) in agriculture and fishery.

Following the revision and rebasing of the National Accounts of the Philippines to    2018 from 2000 as approved in PSA Resolution No. 11, series of 2018, “Approving the General Policy on the Revision and Rebasing of the PSNA”, the the valuation of the performance of agriculture also needs to be revised and rebased. This is to incorporate additional and more comprehensive data to reflect the most recent structure of the agriculture and fishery sector.

Criteria in the Selection of Highlighted Commodities

The valuation of the performance of agriculture covers all agricultural commodities, highlighting selected commodities. For the 2018 base year, the selection of the highlighted commodities was based on the rank of the values of production at constant 2018 prices, inputs from stakeholders in the agriculture and fisheries sector during the consultation workshop and from commodity specialists. Factors considered in choosing the highlighted commodities were high volume of production, high consumption, priority commodities and representation to commodity groups (e.g., cereals, fruits, legumes, citrus, condiments, fruit and leafy vegetables, and non-food and industrial crops, commercial fisheries, municipal fisheries and aquaculture). The highlighted 22 commodities for crops comprised about 95 percent of the total crop production during the base year 2018.  For fisheries, the highlighted 20 commodities accounted for nearly 80 percent of the total fisheries output.   All commodities in the PSA data system for the livestock and poultry were highlighted.

Sources of Basic Data

The generation of the value of production requires data on production and prices.  These data are sourced from the PSA surveys and administrative-based records from other government agencies as follows:

Variable Source

   a. Crops Palay Production Survey (PPS)
  Corn Production Survey (CPS)
  Crops Production Survey (CrPS)
   b. Livestock and Poultry Backyard Livestock and Poultry Survey
  Commercial Livestock and Poultry Survey
  Compilation of Data From Slaughterhouses
  and Poultry Dressing Plants
   c. Fisheries Quarterly Municipal Fisheries Survey
  Quarterly Inland Fisheries Survey
  Quarterly Commercial Fisheries Survey
2.  Farmgate Prices
    a.  Crops Farm Prices Survey
    b.  Livestock and Poultry Farm Prices Survey
    c.  Fisheries Quarterly Municipal Fisheries Survey
  Quarterly Inland Fisheries Survey
  Quarterly Commercial Fisheries Survey
  Quarterly Aquaculture Survey
3.  Administrative Data
a. Volume of Production of Centrifugal Sugar and Raw Sugar Sugar Regulatory Administration (SRA)
b. Dairy Production and Price for Goat and Cattle National Dairy Authority (NDA)
c. Dairy Production and Price for Carabao Philippine Carabao Center (PCC)
d. Slaughter Data from Licensed to Operate Meat Establishments (LTOMEs) National Meat Inspection Service (NMIS)
e. Slaughter Data from Locally Registered Meat Establishments (LRMEs) Local Government Units (LGUs)
f. Volume and Value of Commercial Fish Unloadings Philippine Fisheries Development Authority (PFDA), Local Government Units (LGUs) and Privately Managed Landing Centers
g. Volume and Value of Municipal Fish Unloadings Philippine Fisheries Development Authority (PFDA) and Local Government Units (LGUs)

Estimation Procedure

At Constant 2018 Prices

Formula:

VPo = Qt X FGPo

Where:

VPo = Value of production at constant prices; 
Qt = Volume of production for the current period; and 
FGPo = Farmgate price at constant 2018 prices

At Current Prices

Formula:

VPt = Qt X FGPt

Where:

VPt = Value of production at current prices; 
Qt = Volume of production for the current period; and 
FGPt = Farmgate price at current prices

Definitions

Value of Production at Constant Prices – refers to valuation of transactions, wherein the influence of price changes from the base year to the current year has been removed.

Value of Production at Current Prices - is the value based on prices during the reference year; nominal year.
