RiceFloodIT: Water Management in the Italian Rice Paddies Estimated from MODIS data

This repository includes two datasets used in Ranghetti et al. (2018) and Ranghetti & Boschetti (2022) to analyse the magnitude of a decreasing trend in the extent of submerged rice paddies during the rice-sowing period in the Italian rice district: methods used to generate these data from MODIS remote sensing imagery are described in these papers.

• ffavg_2021.csv: this dataset includes values of yearly FF_avg (averaged Flooding Fraction) at pixel level. Each record represent the FF_avg value of a specific pixel in a specific year.
  • x and y identifies the latitude and longitude of each record (in UTM32 coordinates);
  • subdistrict represent the sub-district ID of each pixel ("A" to "G");
  • year is the year whose each record refers to;
  • ff is the FFavg value (range 0-1);
  • count is the number of MODIS images used to generate each FF_avg aggregated value.
• ws_2021.csv: this dataset includes values of WS (proportion of Water-Seeded rice surface) at sub-district and district levels.
  • subdistrict represent the sub-district ID of each record ("A" to "G", plus "all" which identifies values aggregated at district level);
  • year is the year whose each record refers to;
  • ws is the WS value (range 0-1);
  • count is the number of pixels used to generate each WS aggregated record.

Current data version (2021.01) includes estimated values in the period 2000-2021.
