Integrating satellite-based mapping and field observations for improved decisions on rice

We need information for improved decision making on rice

We need information for improved decision making on rice

accurate accurate, detailed accurate, detailed, timely accurate, detailed, timely, location-specific

like remote sensing, crop modeling, smartphones and web platforms… to generate information on the where, when, and how much of rice, as well as crop health and flood/drought damage assessments.

Leveraging on new technologies…

Field surveys • Location • Field characteristics • Crop growth • Yield (Crop cut) • Animal pests,

diseases and weeds

Smartphone-based surveys

Smartphone-based surveys

Farmer interviews • Crop

management practices

• Farmer’s estimated yield

• Main – RIICE/PRISM ODK Collect – Pocket LAI

• Support – Zxing Barcode reader – GPS Status – Aldiko Book Reader

• Optional – Camera FV Lite – GPS Essential

Applications

ODK collect

Pocket LAI

• An app that indirectly estimates leaf area index (LAI).

• Application developed by the University of Milan

Remote sensing

Sentinel-1a • Launched 3rd/April/2014 by ESA • 12 day repeat frequency • 20m resolution • Free and open access to imagery • SAR sensor – perfect for rice • A second satellite - Sentinel-1b - will further increase monitoring capabilities, one image every 6 days

Coverage

radar images vs optical images

Settlements, built up areas

Canals/Rivers

Ponds, aquaculture

Rice area, colours indicate different

SAR data in RIICE are provided by ASI/e-GEOS and GISTDA from COSMO-SkyMed and by InfoTerra GmbH from TerraSAR-X.

Mapping rice from space

Changes in these images over time are used to map where rice is grown, when it is grown and how much rice is harvested
