PRiSM is the first to operate a nationwide satellite imaging and Information and Communications Technology-based rice monitoring system in Southeast Asia. It generates data and information on planted rice area, yield, and extent of rice areas at risk due to natural disaster (e.g. flood, typhoon, drought).
All PRiSM data products are stored and shared through its online portal that serves as a one-stop hub for target clients such as planners and decision-makers in the Department of Agriculture (DA) and other government agencies that needs reliable and up-to-date rice production data for the development of agricultural policies and technologies as well as for drafting of emergency management plans (ex. disaster preparedness, emergency response, etc.)
Satellite-based rice monitoring towards a rice-secure Philippines
To support the Department of Agriculture In making informed decisions for policy formulation and planning through provision of timely and reliable rice information based on remote sensing, crop modeling, and information and communication technology.
- To provide reliable, location-specific, and timely information on rice area planted, planting dates, yield estimates, and flooded rice area due to heavy rains and tropical cyclones and drought-affected rice areas; and
- To engage in Research for Development to improve operations in response to the needs of the Department of Agriculture.
WHAT WE DO
MAPPING AND MONITORING
PRiSM aims to provide a reliable, location-specific, and timely information on rice area planted, planting dates, yield estimates, and areas at risk and damaged due to flood and drought. It uses technologies on remote sensing, crop growth simulation models, geographical information system, smartphone-based survey forms, cloud computing infrastructure and online information system.
A regular ground monitoring is done every 12 days based on the schedule of the satellite pass or the time when the satellite is visible above the Philippine horizon and captures information from the ground. To validate the images captured by the satellite, the PRiSM data collectors capture ground data in 1,140 selected monitoring field across the country within three days upon satellite pass. The collected ground data have been used in fine-tuning the parameters in rice mapping software (MAPscape-RICE), to validate the generated rice maps, and as input for running the ORYZA crop model.
On the other hand, PRiSM gathers around 1,934 ground information on rice and non-rice to validate the map produced and assess the accuracy of the data.
Since our country is prone to natural calamities, PRiSM also developed and implemented protocols that help the country monitor the damaged rice areas due to flood and drought. PRiSM releases information on rice area at risk and damaged rice areas. Through this intervention, PRiSM is able to provide information necessary for agency preparedness to natural calamities, seed distribution, and other required interventions as well as assessment of potential rice production shortfalls.
Experts from PRiSM serve as Resource Persons during workshops and trainings related to geographical information system, field data collection protocols, and online data management system. These trainings capacitate the PRiSM partners on using the PRiSM data products.
From 2014 to 2018, a total of 358 training-workshops were conducted by PhilRice and IRRI, of which 197 were for the DA RFOs and other DA agencies.
