This CropWatch Bulletin covers 89 major crop-producing countries worldwide, monitoring a wide range of indicators related to crop growth and agricultural conditions. These monitoring datasets provide strong support for agricultural decision-making and forecasting, enabling countries to better understand crop growth dynamics, agroclimatic conditions, and overall agricultural production trends.

For each country, CropWatch provides 11 major categories of agroclimatic and crop condition indicators. Through these indicators, the CropWatch offers comprehensive and accurate data support for national agricultural monitoring, helping governments and stakeholders track changes in crop growth and climate conditions in a timely manner, thereby providing a scientific basis for agricultural policy and management decisions.

1. Phenological Charts of Major Cereal and Oilseed Crops

These charts illustrate the growth cycle of major cereal and oilseed crops from sowing to maturity. They provide essential information for analyzing crop development stages and growth duration throughout the season.

2. NDVI-Based Crop Condition Profiles

Derived from Normalized Difference Vegetation Index (NDVI) data, these profiles depict the temporal dynamics of vegetation cover during different growth stages, clearly reflecting crop growth conditions and vigor.

3. Maximum Vegetation Condition Index (VCIx)

These maps show the optimal vegetation conditions across regions based on NDVI values, offering insights into crop growth potential and the overall production outlook.

4. Spatial Clustering Maps of NDVI Anomalies (Compared with the 5-Year Average)

These maps display deviations of current NDVI values from the five-year average, enabling identification of regions with abnormal crop growth and potential agricultural risks.

5. Temporal Profiles of NDVI Anomalies

NDVI anomaly profiles illustrate the temporal evolution of crop growth and its deviation from historical averages, allowing assessment of whether current crop development is within normal ranges or under stress.

6. Precipitation Time Series

These time series charts depict trends in regional precipitation, providing key information for analyzing water resource variability and assessing its impact on crop growth and yield formation.

7. Temperature Time Series

Temperature time series charts display fluctuations in regional temperature. Comparing current and historical temperature patterns helps assess the influence of thermal conditions on crop development.

8. NDVI-Based Crop Growth Profiles by Agroecological Zone

These charts present NDVI-derived crop growth conditions within different agroecological zones, reflecting the spatial heterogeneity of crop performance across ecological regions.

9. Crop Production Index (CroPI) Time Series

This time series illustrates variations in the Crop Production Index, allowing decision-makers to track agricultural production dynamics and identify potential yield risks in advance.

10. Agroclimatic Indicators Compared with the 15-Year Average (15YA)

These tables summarize agroclimatic conditions relative to the 15-year average, including cumulative precipitation, mean temperature, photosynthetically active radiation (PAR), and potential biomass accumulation. They provide valuable insights into the long-term impacts of climatic variations on agricultural production.

11. Agronomic Indicators Compared with the 5-Year Average (5YA)

These tables present crop condition indicators over the past five years, such as the CALF, VCIx, CroPI. Comparing these data with past observations helps reveal both normal and abnormal fluctuations in agricultural production trends.

The agroclimatic and crop condition datasets, together with the spatial distribution maps of crop growth conditions for 89 monitored countries during the current reporting period, are available at: http://cloud.cropwatch.com.cn/web/report/graphlist?id=316
