This study aims to assess the impact of future climate change on rainfed wheat yield in the semiarid Eastern High Plai[...]Article
Simulating organic agriculture is a considerable challenge. One reason is that few models are capable of simulating crop-pest interactions and the yield losses they cause. Here, a recently developed process-based crop-pest model (Pest-EPIC) was [...]Article
Zero tillage (ZT) is recommended for dryland farming because it enhances retention of residual soil moisture. However, it is not always clear whether this translates to an economic advantage over conventional tillage, which helps in controlling [...]Article

Huijbregts |Eco-efficiency, defined as the economic profit per unit of environmental impact, can largely differ between farms that produce the same crop. Understanding the underlying drivers of differences in eco-efficiency can help to identify effective op[...]Article
The crop yield modeling remains a central input in the assessment of climate change risks. This study aims at investigating to what extent that rainfall, temperature and runoff could ably transmit significant information needed for analyzing and[...]Article
