Idea Overview:

The Problem:

 Hungary’s agriculture faces a "double-edged sword." On one hand, the Great Hungarian Plain is experiencing rapid desertification and drought (peaking in 2022). On the other, the Tisza River and smaller agricultural channels suffer from high BOD (Biochemical Oxygen Demand) and bacterial threats due to cross-border industrial runoff and untreated fertilizer leaching.

The Solution: 

we are proposing an end-to-end system that uses EU Space Data to identify pollution hotspots in real-time. This triggers autonomous bio-purification units (floating filter islands or automated sluice gates) that treat the water before it reaches farm irrigation systems, ensuring "resilient farming" even during low-water period.

EU Space Technologies :

Copernicus Sentinel-2: 

we will use multispectral imagery to monitor Chlorophyll-a levels and Turbidity. High levels of these are "proxies" for high BOD and bacterial blooms.

Copernicus Sentinel-1: 

Its radar data helps monitor soil moisture levels in the Great Plain, identifying which farms are most at risk of using contaminated, stagnant water during droughts.

Galileo (GNSS):

 This provides the high-precision positioning (sub-meter accuracy) required for your "autonomous bio-purification" units to navigate river channels or for drones to take physical water samples at the exact spot where the satellite detected a "red zone."

EU Space for Water: 

How it contributes ; Challenge #2: Tracking and Preventing Water Pollution.

Proactive vs. Reactive: 

Instead of waiting for laboratory results that take days, your tool uses satellite "early warning" to stop contaminated water from entering the food chain.

Cross-Border Safety: 

Since many of Hungary's water problems (like the Tisza plastic and heavy metal issues) originate outside the country, space data is the only way to track pollution plumes as they cross the border in real-time.
