Agricultural Stress Index System (ASIS) is a global agricultural drought monitoring system developed and operated by United Nations Food and Agricultural Organization (UN FAO). It combines the...

The Weighted Mean Vegetation Health Index (Weighted Mean VHI) allows the user to assess the severity of the drought from the start of the growing season, examining the vegetation health and the...

Countries with unfavourable prospects for current crops are countries where prospects point to a shortfall in production of current crops as a result of a reduction of the area planted and/or...

Countries requiring external assistance for food are expected to lack the resources to deal with reported critical problems of food insecurity. Food crises are nearly always due to a combination of...

The Vegetation Condition Index (VCI) evaluates the current vegetation health in comparison to the historical trends. The VCI relates current dekadal Normalized Difference Vegetation Index (NDVI)...

Complementary to Agricultural Stress Index (ASI) which detects the severe and extreme drought, Drought Intensity is another quick-look indicator in ASIS that facilitates the early understanding of...

Phenology is defined as the study of the timing of recurring biological cycles and their connection to the climate. Changes in the vegetation phenology, including the start of season, the length of...

The Weighted Mean Vegetation Health Index (Weighted Mean VHI) allows the user to assess the severity of the drought from the start of the growing season, examining the vegetation health and the...

Historic Agricultural Drought Frequency Maps depict the frequency of severe drought in areas where 30 percent/50 percent of the cropland/grassland has been affected. The historical frequency of...

The Global Information and Early Warning System on Food and Agriculture (GIEWS) continuously monitors food supply and demand and other key indicators for assessing the overall food security...

Crop/Pasture Phenology is a reference dataset used by ASIS. Phenology is defined as the study of the timing of recurring biological cycles and their connection to the climate. Changes in the...

The Vegetation Health Index (VHI) illustrates the severity of drought based on the vegetation health and the influence of temperature on plant conditions. The VHI is a composite index and the...

Complementary to Agricultural Stress Index (ASI) which detects the severe and extreme drought, Drought Intensity is another quick-look indicator in ASIS that facilitates the early understanding of...

The Agricultural Stress Index (ASI) is a quick-look indicator that facilitates the early identification of cropped land with a high likelihood of water stress (drought). ASI related products (maps,...

ASIS non seasonal indictors include: NDVI anomaly, Vegetation Condition Index (VCI) and Vegetation Health Index (VHI). These indices can be used to monitor the areas where vegetation may be...

Agricultural Stress Index (ASI) - Near Real Time is a quick-look indicator that facilitates the early identification of cropped land with a high likelihood of water stress (drought). It depicts the...

Crop/Pasture phenology is very important reference information to calculate the seasonal indictors in ASIS. As the calculation of seasonal indictors (ASI, Drought Intensity and Mean VHI) includes...

Seasonal indicators are designed to allow easy identification of areas of cropped land/grassland with a high likelihood of water stress (drought). The indicators are based on remote sensing data of...
