Was the rain-fed wheat and barley season in your sub-district worse than normal?
The spring green-up peak (March–April) of every year from 2001 to 2025 on 250 m cells, compared with the 25-year median, per sub-district. In 2025 the national peak was -32.0% versus normal.
In short
The 2025 season was -32.0% versus normal, ranking 1 of 25 from worst.
118 sub-districts had a very poor and 62 a poor 2025 season, out of 271 with greening land.
Worst seasons: 2025 (-32.0%), 2008 (-24.5%), 2022 (-18.8%).
Who it is for
Food-security and early-warning organisations, agricultural directorates, drought researchers, and grain and fodder investors.
Method: what we add to the raw data
- 16-day NDVI composites at 250 m for March and April of every year were used, removing unreliable cells (cloud and shadow).
- Each cell's yearly peak is the highest value among the season's composites, representing maximum growth of rain-fed crops and rangeland.
- Normal = the 25-year median peak (half the seasons below, half above).
- Only land that actually greens up (median 0.2 or more) is used, so bare Badia does not dilute averages.
- Each season is rated: very poor (≥25% below), poor (10–25%), normal (±10%), good (≥10% above).

Limitations
- The index measures greenness, not tonnes; it shows the season's direction, not harvest quantity.
- Irrigated land stays green in drought, softening the drop in sub-districts with irrigation.
- 250 m cells mix small fields with their surroundings.
