This document discusses 3 use cases for agro-environmental services. Use case 1 aims to improve access and sharing of geo data by addressing challenges with data inventory, publishing, and communication. Use case 2 examines structural changes to water canals by mapping a canal in Slovakia and analyzing subsidized land nearby. Use case 3 identifies dynamic landscape changes over time through vulnerability analysis and analyzing landscape structure changes using data like Corine Land Cover and NDVI indexes. The team behind this work includes representatives from universities and government organizations in Slovakia.
3. 1. Motivation
Main motivation of the challenge remained twofold:
● Identify and stimulate an access to agri & enviro data
● Investigate the possible use cases demonstrating the utilisation of above data
Sources & geographical scope
● INSPIRE, Copernicus, Open Data, eGovernment and private data resources
● Selected pilot regions:
○ SK National level
○ Eastern Slovakia
Challenge use cases

3. Dynamic changes of landscape identification
4. 2. Use case # 1 Data access and utilisation
Global aim: Support geo data identification and sharing
Current challenges:
● Data inventory
● Data publishing/sharing
5. 2. Use case # 1 Data access and utilisation
Global aim: Support geo data identification and sharing
Current challenges:
● Data communication
● External data integration (Meteoblue)
6. 2. Use case # 2 Water canal structural changes
Global aim: Prove/disprove the necessity of maintenance of artificial canals’ for
the purposes irrigation and prevention of extreme droughts’ impacts.
Current challenge:
Find a more precise spatial representation
of the Somotor canal.
Fun facts about Medzibodrožie; In 2020:
● 62.23 % (256.34 km2
) of Medzibodrožie’s areas was subject to requests of
subsidization from the subsidy system of Slovakia’s Agricultural Paying
Agency
● 45 % (115.864 km2
) of requests were subject to Cereals production
● 12 % (31.525 km2
) of requests were subject of land maintenance (fallow
lands, permanent grasslands etc.)
