Article Synopsis
- Researchers assessed reactive nitrogen losses in Austria under four climate change scenarios from 2041-2070 using two nutrient models (MONERIS and SWAT).
- Both models showed similar findings regarding inorganic nitrogen loads in water, with minor differences, while highlighting the importance of factors like fertilizer type and climate conditions on nitrogen losses.
- The study's results emphasize the significance of understanding nitrogen transport pathways in the context of climate change for effective policy-making and resource management.
Article Synopsis
- * The study analyzes regional N budgets, focusing on agricultural production, consumption, and N emissions across Austria, using material flow analysis to identify losses and nitrogen use efficiencies (NUE).
- * Findings show significant regional disparities: alpine regions have low N inputs and inefficient NUE, while lowland areas exhibit higher N efficiency but face groundwater nitrate issues, reflecting the complex interplay between production systems and environmental factors.
The identification of critical source areas (CSAs) is a key element in a cost-effective mitigation of diffuse emissions of phosphorus from agricultural soils into surface waters. One of the challenges related to CSAs is how to couple complex, data-intensive fate and transport models with easy-to-use information on field level for management purposes at the scale of large watersheds. To fill such a gap and create a bridge between the two tasks, this study puts forward the new Particulate PhozzyLogic Index (PPLI) based on the innovative combination of the results of a complex watershed model (in this case the PhosFate model) with fuzzy logic.
