High-yielding traits can potentially improve yield performance under climate change. However, data for these traits are limited to specific field sites. Despite this limitation, field-scale calibrated crop models for high-yielding traits are being applied over large scales using gridded weather and soil datasets.

Article Synopsis
  • * Research using advanced wheat simulation models indicates improved wheat genotypes can boost yields by 16% using current nitrogen fertilizer levels.
  • * To reach a potential 52% increase in yield under severe climate change conditions, nitrogen fertilizer use would need to quadruple, which could exacerbate environmental impacts, highlighting the need for better nitrogen management.

Improved understanding of crops' response to soil water stress is important to advance soil-plant system models and to support crop breeding, crop and varietal selection, and management decisions to minimize negative impacts. Studies on eco-physiological crop characteristics from leaf to canopy for different soil water conditions and crops are often carried out at controlled conditions. In-field measurements under realistic field conditions and data of plant water potential, its links with CO and HO gas fluxes, and crop growth processes are rare.

Agricultural Biodiversity dynamics has been evaluated by social metabolism or by landscape structure-function analysis. In this study, by using ELIA modeling, we used both methods in combination to understand how the interplay between social metabolism and landscape structure-function can affect biodiversity pattern distribution. We used energy reinvestment (E) as an indicator of social metabolism and landscape heterogeneity (Le) as an indicator of landscape structure-function.

Article Synopsis
  • Finding a common understanding of the term "landscape" is essential for effective collaboration among interdisciplinary scientists in sustainable agriculture research.
  • Many studies use the term "landscape" in vague or varying ways, causing confusion and hindering cooperation.
  • A new, flexible definition of "landscape" is proposed that can adapt to different research contexts, allowing for clearer communication and understanding across disciplines.
