Agricultural Drought Areas in the North China Plain at 500m Resolution, 2006–2019

A 500-meter resolution dataset of agricultural drought areas for summer-harvest and autumn-harvest crops in the North China Plain from 2006 to 2019. It was generated by Jiali Shi of the Chinese Academy of Sciences to address limitations in coarser-resolution drought archives. The dataset delineates three degrees of drought impact: drought-covered area, drought-damaged area, and crop failure area.

Use Cases

• Generate synthetic regional drought information based on the three-degree drought classification.
• Support impact-based agricultural drought monitoring and prediction using the high-resolution spatiotemporal data.
• Optimize agricultural water management strategies based on historical drought patterns for summer and autumn crops.
• Assess food security risks by analyzing the extent of drought-damaged and crop failure areas over a 14-year period.

Strengths

• 500-meter spatial resolution, which is finer than many accessible agricultural drought archives.
• Covers a 14-year time range from 2006 to 2019 for the North China Plain.
• Distinguishes between three specific agricultural drought impact areas: drought-covered, drought-damaged, and crop failure.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count and file size are unknown, which may limit suitability assessment.
