India’s 2026 monsoon ended 12.6% below normal. East/Northeast India recorded its lowest seasonal rainfall since 1901. What should satellite data be tracking before the Rabi season?

The 2026 southwest monsoon has ended with an all-India rainfall deficit of 12.6%—about 759.4 mm against a normal of 868.6 mm, according to IMD figures reported this week.

The spatial pattern is more concerning than the national average:

  • East and Northeast India: 1,016.3 mm, only 74% of long-period average; lowest since 1901
  • Southern Peninsula: 542.0 mm, 76% of LPA; fourth-lowest since 1901
  • El Niño conditions are being cited as a major driver

This is not just a weather headline. It affects soil moisture, reservoir levels, irrigation planning, crop stress, and ultimately Rabi sowing decisions.

From a geospatial perspective, the useful question is: where exactly is the stress emerging, and how severe is it compared with previous seasons?

A practical monitoring stack could combine:

  • IMD gridded rainfall for the seasonal deficit baseline
  • Sentinel-2 / MODIS NDVI and EVI time series for vegetation stress
  • SMAP soil-moisture anomalies for root-zone conditions
  • Reservoir extent and surface-water mapping for irrigation availability
  • District-level cropping patterns to identify exposed crop belts

The key is not to wait for yield estimates after harvest. Satellite data can help identify stressed districts earlier, especially in rainfed systems, so that irrigation, procurement, insurance, and relief planning are more targeted.

What datasets or indicators would you prioritize for a Rabi-season early-warning map?

What can satellite data tell us about the economy?

Can we understand economic activity by looking at the Earth from space?

A lot of economic analysis starts with reported numbers: company revenues, trade data, industrial output, and government statistics.

But much of the underlying economic activity happens in physical places.

Factories expand. Ports get busier. Construction progresses. Agricultural patterns change. Storage facilities fill up.

Satellite imagery and geospatial data can help observe some of these changes, sometimes before they appear in conventional reporting.

The interesting part isn't simply identifying a building or counting ships. It's connecting those observations to a meaningful economic question.

For example:

  • Is new industrial capacity actually becoming operational?
  • Are port activity and infrastructure development moving together?
  • Can changes in land use help us understand shifts in agricultural production?

Of course, imagery alone doesn't establish economic output. It needs to be combined with other data and validated.

Where do you see the most useful applications of satellite intelligence in business, investing, or trade analysis?
