Argentina

Project Overview

Centered in San Antonio de Areco (Buenos Aires, Argentina), a small area (20 x 20 Km) was selected where high frequency crop and environmental monitoring is being performed. An extended area (70 x 70 Km) is being surveyed with lower frequency for crop mapping and identification of phenological events.

  1. Crop identification and Crop Area Estimation: Crop identification. We are testing several classification methods using optical images and RADAR images and its combination. During last campaign we continued obtaining data from the original JECAM/ SIGMA area as well as over a minimum dataset (MDS) area of 20 x 20 km with higher density collection. This small area matches with RADARSAT-2 Fine Quad Pol acquisitions during this campaign that we are collecting for the SAR intercomparrison experiment. We developed an intercomparisson of methodologies for cropland identification together with other JECAM/ SIGMA sites (China, Russiz, Ukraine, Brazil, and Belgium). We are moving from local to regional estimation of crop land and crop type. We are testing different sampling methodologies and different data sources together with other JECAM sites.
     
  2. Crop Rotations: Crop rotations in the last 6 campaigns are described and analized. We expect to write a manuscript during 2017. 
     
  3. Soil Moisture: Analysis of its effects on RADAR signal.
     
  4. Yield Prediction and Forecasting: We are working in an intercomparisson study for yield estimation at coutry level with SIGMA/ JECAM partners from Russia, China, Ukraine, and Africa leaded by Alterra (Wageningen, The Netherlands). We are also working in the estimation of biophysical parameters at field level using optical and RADAR images.
