Core Activities

RICE AREA MAPPING

PRiSM uses Synthetic Aperture Radar images from Sentinel 1A to map the country's total rice area every cropping season. By using the mapping software (MAPscape-Rice®) developed by sarmap and the available ground data gathered from field monitoring sites across the country, PRiSM can delineate rice areas, detect rice planting dates and growth stages, identify rice areas at risk or affected by droughts and floods, and generate crop growth information needed for rice yield estimation.

YIELD ESTIMATION

The use of crop growth simulation model (ex. ORYZA) is the backbone of the PRISM rice yield estimation system due to its capability to capture the complex and dynamic interactions among rice genotypic characteristics, environment, and crop management as well as their collective effects on rice growth and yield. The minimum data requirements of crop models to simulate the rice growth and yield are daily weather, soil profile information, agronomic practices, and varietal characteristics.

 

FIELD MONITORING

Field monitoring visits, in selected rice fields, are conducted within the cropping season to collect data on field characteristics, crop management practices, field status, crop stages, and production data. Field monitoring and validation are also conducted to assess the rice crop damages due to flood and drought.

Farmer interviews are conducted using smartphone-based forms and applications. All data collected are submitted to a secure online database for management and processing.

 

CAPACITY BUILDING

PRISM regularly conducts training and retooling workshops to strengthen the capacity of its technical staff and DA regional implementers to carry out their tasks competently. Other capacity-building activities of PRiSM are establishing networks and collaboration with other government agencies, sustaining engagement with local partners, development and integration of system infrastructures, and continuous updating of PRiSM operational protocol.
