The Szigetköz region in northwest Hungary, covering almost 36,500 hectares, is the largest semi-natural flood area in the Danube Valley and a Natura 2000 site. It features a rich diversity of flora and fauna, interspersed with rivers and sandbanks, and is predominantly an agricultural landscape with forests, meadows, swamps, and watercourses.

Despite previous human impacts, the region's ecology remains shaped by periodic floods. Szigetköz region is notable for its high crop yields, particularly wheat, corn, sunflower, and alfalfa, which are 15-20% higher than the national average.

Agricultural practices vary based on groundwater levels, with shallow-rooting crops near high groundwater and deeper-rooting crops where levels have decreased. Currently, only 8-13% of farmland is irrigated due to the high costs and potential negative effects on soil.

Climate change is significantly impacting agriculture, with extreme heat, rainfall events, and changes in precipitation patterns expected to reduce crop productivity. Variability in crop yields due to extreme weather events, pests, and diseases is also anticipated to increase. Temperature changes and altered growing seasons may facilitate the spread of certain species, like insects and invasive weeds, further affecting crop yields. Adapting agriculture to extreme weather conditions is essential, necessitating a departure from traditional practices that may no longer be suitable.

Real-time field data, including soil condition, nutrient levels, water content, and meteorological data, is becoming increasingly crucial for informed decision-making. Understanding these processes and trends is vital for implementing effective solutions. By utilizing real-time information and adjusting farming practices accordingly, such as optimizing input materials and aligning soil work with weather patterns, farmers can mitigate potential yield losses and transition towards nature-based solutions better suited to changing environmental conditions.


trans4num NBS test site

trans4num will conduct experiments in three replications comparing (NBS) with conventional intensive farming systems on a 20-hectare land with a three-year rotation of durum wheat, sorghum, and soya. The trials will take place at Mecsér experimentation sites, involving practice partners and local stakeholders. Soil quality will be assessed using fast sensor-based technology to evaluate the impact of NBS on soil structure, organic matter, and yield improvement.

Objectives include testing and monitoring the effects of NBS, developing a monitoring and decision support system for farmers, and preparing educational materials to promote the economic benefits of NBS and address associated challenges. Monitoring methods involve soil and plant sampling, soil profile analysis, remote sensing technologies for crop health monitoring, yield monitoring, and biodiversity assessments.
