Rice: Vegetation health
The VHI (Vegetation Health Index) is an indicator that monitors vegetation health. It combines information on plant vigor (NDVI) and land surface temperature (LST) to detect drought stress, heatwaves, or other climatic events. High values indicate healthy vegetation, while low values signal critical conditions for crops.
The first chart shows the current condition of the selected crop across the various states within the analyzed world regions.
In the second section of the page, a historical comparison is available for all states, focusing on the selected crop..

In the chart below, the land conditions related to the selected crop are shown.
The chart is organized by geographic area, with each country represented by a colored dot.
The vertical position of each dot indicates the health of the land in that country.
The color and size of the dot represent the total production of the crop.
Top producers are shown as large purple dots, while countries with lower output appear as smaller yellow dots.
RICE - Historical trend by Region
The following charts show the historical trend of the health conditions (VHI index) of Rice crops in the different Regions. The purple dotted line represents the threshold below which the vegetation is in a situation of significant stress, which can negatively affect crop yields. The colored areas indicate the periods when the level of the VHI index went under such stress conditions, going from orange (less intense stress) to dark red (more intense stress).
