Historical ASAP warning frequency

The 2 maps show the historical frequency of ASAP warnings of level 2 or higher at the sub-national level and can be interpreted as sensitivity to "agricultural drought conditions". The color intensity is proportional to the frequency of ASAP warnings, i.e. the percentage of dekads with a warning, out of the total number of active dekads in the period 2003-2022.

REFERENCE DATA

Administrative Boundaries

ASAP information is provided at two spatial levels: national (Gaul0) and sub-national (Gaul1). In particular, hotspots are related to national units while warnings to sub-national units. An additional more detailed sub-national level (Gaul2) is available for a set of selected countries of interest, for which we provide aggregated statistics (see "Indicator Statistics" sub section). The reference spatial layers (gaul0_asap, gaul1_asap, gaul2_asap) are derived from the The Global Administrative Unit Layers (GAUL) dataset, implemented by FAO within the CountrySTAT and Agricultural Market Information System (AMIS) projects. The original data sets were adapted to match the specific ASAP requirements (e.g. in some countries, the sub-national units were aggregated, in others they were split in smaller units) and the geometry was simplified (e.g. the number of vertex reduced and small islands removed). The geographic and thematic information contained does not imply a policy position of the European Commission. Here you can download the three layers as shapefiles. These layers can be used to visualize the historical time series of Hotspots, Warnings and Indicator statistics (see related sections below). The key fields are asap0_id, asap1_id and asap2_id. Please note that these layers are intended for visualization at a broad scale and due to the simplification of the geometries, the original topology is not always preserved.

Land Cover Masks

Global crop and rangeland masks at 0.004464285715 deg resolution (about 1/4 square kilometer). Each pixel represents the area fraction of the specific cover (i.e. percentage of the pixel with crops/rangeland). Data ranges between 1 and 100 showing the % value. These layers were generated for ASAP, combining existing data sets (Fritz, S., Lesiv, M., Perez Guzman, K., See, L., Meroni, M., Collivignarelli, F. and Rembold, F., Development of a new cropland and rangeland Area Fraction Image at 500 m for the ASAP system, Publications Office of the European Union, Luxembourg, 2024, doi:10.2760/32935, JRC137153. doi:10.2760/32935). The data sets were last updated on 01-12-2023 (version 04).

Phenology

The mean growing season period is defined by a satellite-derived phenology computed on the long-term average of 10-day MODIS/VIIRS FPAR data. Data preprocessing was done with an improved version of the filtering algorithm of Klisch and Atzberger (2016) starting from MCD15A3H (MODIS), VNP15A2H (Suomi-NPP satellite) and VJ115A2H (NOAA-20 satellite) global data at 500 m spatial resolution.
The following key parameters are retrieved for each pixel: number of growing seasons per year (i.e. one or two); start of season (SOS, occurring at the time at which FPAR reaches 25% of the ascending amplitude of the seasonal profile); time of maximum FPAR (TOM); start of senescence period (SEN, when FPAR drops below 75% of the descending amplitude); and end of the season (EOS, when FPAR drops below 35%).
Phenology timings: the value V in the image is expressed over a 3 years period, from dekads (i.e. ten-day periods) 1 to 108. This is done in order to treat the circular variable "dekad" as an ordinal variable (the mean of SOS cam be computed as the usual average). Example for a season crossing the calendar year:
phenos1 = 30, last dekad of October, phenoe1 = 46, first dekad of April -> T = 46 - 36 = 10
Therefore, to get the timing T in the 1-36 dekad units (calendar year), one can use:
IF V <= 36 THEN T = V
IF 36 < V <= 72 THEN T = V -36
IF V > 72 THEN T = V - 72

Crop Calendars

The national and sub-national crop calendars are based on FAO data and include only crops for which the original calendars match with the ASAP remote sensing based phenology. The file includes the start and end dekad (over the 36 dekads in a year) of the planting period (sos_s and sos_e), the start and end dekad of the growth period (sos_e and eos_s), and the start and end dekad of the harvest period (eos_s and eos_e). The rest of the year is considered out of season. To visualize the information in a GIS environment, use the field asap1_id and join with the spatial layer gaul0_asap (see section Administrative Boundaries).

INDICATOR STATISTICS
ASAP calculates every 10 days average values of all key indicators for each ASAP Gaul 1 unit. These data are used by the ASAP warning classification and can be downloaded with the tool below. You can select a country, an indicator and the land use (crop or rangeland) to get a csv with the complete time series of the 10-day values. This file can be imported directly into the CST tool, in order to use ASAP indicators for yield forecasting. A selected set of countries is also available at Gaul 2 level. In the sub section "Reference Data - Administrative Boundaries" you can download the administrative boundaries as shapefile. You can plot values of indicator on a map by joining the csv files downloaded before with the shapefile of the spatial units (key fields: asap1_is and asap2_id).

YIELD FORECAST

Pre-operational Country-level Yield Forecasting with Machine Learning Algorithms and Agrometeorological Data

Country-level yield forecasts are computed for 77 food insecure countries using machine learning algorithms and agrometeorological data. The system is currently in testing phase and utilizes over 20 years of FAOSTAT yield data and ASAP agrometeorological data to provide in-season prediction of crop yields. Remote sensing and meteorological data are used to extract important information about crop development, including maximum NDVI, average temperature, and the sum of radiation and rainfall. Similar countries are grouped together based on their crop development characteristics to improve the accuracy of the models. Finally, only models that achieved Rcv2 > 0.3 were considered suitable for operational forecasts and retained. If no valid model is retained for a given crop-country, no forecast is available.

Forecast model outputs are provided as pdf and csv files and they report: The forecasted yield for the current season, average yield based on the last five years and the percentage difference between the forecasted and the 5 years average yield, input feature combination (RSTR or TR) and the best pooling approach (All, Main or Individual), root mean square error (RMSE) and the coefficient of determination (R2) in prediction from the hindcasting experiments. PDF files also contain plots of observed and predicted yield values (since 2006) as well as the benchmark model (average of last 5 years). Additional information on the methodology can be found in the Methodology summary.

The latest yield forecast can be downloaded from the yield forecast data download page and they are issued 7 days after the forecast is triggered according to calendar below.

Icon Software Download

As part of its agricultural monitoring for food security activities, the JRC, in collaboration with external partners, has developed several open access desktop applications. In this section, you can download the image time series processing tool SPIRITS (Software for Processing and Interpretation of Raster Image Time Series) and the yield forecasting tool CST (CGMS Statistical Tool). SPIRITS is used for producing some of the anomaly indicators behind the ASAP warnings, whereas selected ASAP indicators can be used as yield proxies by the CST tool.


SPIRITS

Description

SPIRITS (Software for the Processing and Interpretation of Remotely Sensed Image Time Series) was developed by VITO for the Food Security unit of the Joint Research Centre. It is a software environment for analyzing satellite derived image time series for crop and vegetation monitoring in an integrated and flexible analysis environment and with a user-friendly graphical interface. With this toolbox, you can process and examine time series of low and medium resolution sensors. It can be used to perform and to automatize many spatial and temporal processing steps on time series and to extract spatially aggregated statistics. Vegetation indices and their anomalies can be rapidly mapped and statistics can be plotted in seasonal graphs to be shared with analysts and decision makers. This presentation introduces the main features available in SPIRITS. These two papers: Image time series processing for agriculture monitoring and Remote sensing time series analysis for crop monitoring with the SPIRITS software: new functionalities and use examples describe the tool with more details. For additional information, you can read the SPIRITS manual.

Acknowledgments

SPIRITS was programmed by Dominique Haesen and Herman Eerens from VITO. From the side of JRC-MARS the developments were guided by Felix Rembold. In addition, the software further benefited from contributions from various JRC-MARS and VITO researchers, who used the software in their own work or for training sessions in Africa and abroad. The Food and Agriculture Organization (FAO) of the United Nations financially supported the development of a number of additional modules which were specifically developed in the frame of FAO’s Agricultural Stress Index System (ASIS).

CST

Description

CST software is designed to support the development and selection of crop yield forecast models to facilitate national and sub national crop yield forecasting. Time trend analysis of yield statistics is followed by regression or scenario analysis using biophysical indicators to explain yield statistics and search for similar years. Constructed models are used to predict yield of the current growing season.
The CGMS statistical tool has been developed for the MARS unit of JRC in the framework of several MARS related projects (MARSOP, ASEMARS, E-Agri, AGRICAB and SIGMA). These projects contributed to development of the initial version and a number of subsequent updates. The original objective was to support the national crop yield forecasting activities of the MARS Crop Yield Forecasting System (MCYFS). Later, through EU research project like E-Agri, AGRICAB and SIGMA the CGMS statistical tool has been introduced to other (non)-governmental organizations having a mandate in monitoring and forecasting crop production.
CST can be used in connection with SPIRITS to combine image processing with statistical crop yield forecast modelling. A selection of ASAP indicators available in the data download page, can also be used as yield proxies in CST
