Your adaptation margin
How much more can it take?
+4.0 °C
Example · maize → wheat · Bărăgan Plain
The margin is how much hotter, or how much drier, it can get before more than one year in five loses money. Big margin, you can breathe. Small margin, it is time to change the rotation.
Find your marginHow it works
From your field to your risk in three steps
No spreadsheets and no jargon. Everything runs on the land you select.
- 01
Select your field
Search your village, then pick a mapped parcel, draw your field or drop a circle of 1 to 50 ha.
- 02
25 years of NASA data
We pull daily temperature, rain and humidity for that exact spot from NASA, plus soil from SoilGrids.
- 03
Your risk and your options
See if your rotation is safe, tight or over the limit, today and around 2050, and what to change.

What you get
What Hotar does for your farm
The map tool is free. The desktop app adds the full analysis for your whole farm.
Field selection
Draw it, click a parcel or drop a circle. Area and centre are computed for you.
Adaptation margin
How many degrees warmer and how much less rain your rotation takes before bad years become too frequent.
Stress test
Replay hotter, drier seasons on your own weather record and see where each crop gives way.
Futures to 2050
NASA NEX-GDDP-CMIP6 climate projections, scaled down to your location.
Rotation advice
Compare rotations on income, risk, soil and water, and get three clear options.
AI explanations in Romanian
Plain-language answers, with every number checked against the simulation.
PDF report
A clear climate and crop plan summary for your bank, APIA or AFIR file.
Alerts
A heads-up when heat or drought is coming for your fields.
The data
Built on real NASA data
Every number comes from a named public source, and anything illustrative is labelled as such.
NASA POWER
In the free mapDaily temperature, rain, humidity and sunshine since 2001, on a grid of about 50 km. The base of every analysis.
MODIS
In the free mapSatellite vegetation index (NDVI) every 16 days at about 250 m: how green and dense crops are.
HLS and Prithvi-EO
In developmentHarmonized Landsat and Sentinel-2 imagery at 30 m, plus NASA and IBM's Prithvi model for crop mapping.
SMAP
In developmentSoil moisture measured from space, useful for spotting drought stress early.
GPM IMERG
In developmentSatellite rainfall estimates at about 10 km, to check recent rain where there are no stations.
NEX-GDDP-CMIP6
In the desktop appClimate projections to 2100 from many models, downscaled to about 25 km.
NASADEM
In developmentElevation and slope at 30 m, for erosion and water-flow context.
GIBS
In the free mapNASA's imagery service. It serves the vegetation layer you see on the map.
Also used: ISRIC SoilGrids (soil), OpenStreetMap (places and parcels), Esri World Imagery (base map).

Questions
Questions, answered
Where does the data come from?
Weather comes from NASA POWER (daily, 2001–2025), soil from ISRIC SoilGrids, satellite vegetation from NASA MODIS through GIBS, and climate projections from NASA NEX-GDDP-CMIP6. Each number in the app shows its source and period.
Is the map really free?
Yes. You can select land, read its climate record and see how a typical rotation could be affected, with no account. The free plan keeps one saved field.
How accurate are the numbers?
They are a planning aid, not a guarantee. NASA weather is on a grid of about 50 km and soil at 250 m, so very local effects such as a valley or irrigation are not captured. We always say which numbers are approximate.
What is the adaptation margin?
It is how many degrees of extra warming, or how much less rain, your rotation can take before more than one year in five loses money. A small margin means you are close to the edge.
Does it work outside Romania?
Yes, for any point on Earth with NASA data. Mapped farmland parcels depend on OpenStreetMap coverage; if your parcel is missing you can draw it.
What happens to my land data?
The outline you draw stays in your browser and is saved only on your device. To get weather and soil we send the centre point of your land to NASA POWER and ISRIC, and place searches go to OpenStreetMap.
Can I use the reports for my bank, APIA or AFIR?
The PDF report is a clear supporting document for your file. It is not a certified expert opinion, and the institution decides what it accepts.
When can I download the desktop app?
The download buttons on this page will go live when the first release is ready. Until then, the free map is fully usable.
