American Journal of Agricultural Economics, EarlyView.Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

American Journal of Agricultural Economics, EarlyView.Abstract Our general interest is in global trade loss from livestock pathogens, specifically exports. We adopt a causal inference approach that considers animal disease outbreaks over time as non‐staggered binary treatments with the potential for switching in (infection) and out of treatment (recovery) within the sample period. The outcome evolution of

Distributed Hydrological Model Considering Saturation-excess Runoff Mechanism
工程科学与技术, 2019 Flood forecasting is usually based on the simulation of rainfall-runoff models. In this study, based on the saturation excess runoff mechanism, a distributed three-source runoff model was developed for rainfall-runoff simulation in mountainous areas ...

Simulating the hydrologic cycle in coal mining subsidence areas with a distributed hydrologic model [PDF]
Scientific Reports, 2017 AbstractLarge-scale ground subsidence caused by coal mining and subsequent water-filling leads to serious environmental problems and economic losses, especially in plains with a high phreatic water level. Clarifying the hydrologic cycle in subsidence areas has important practical value for environmental remediation, and provides a scientific basis for ...

American Journal of Agricultural Economics, EarlyView.Abstract This study examines the impact of soil erosion on agricultural land values in the United States (US) Midwest. Based on a novel county‐level panel data set with information on soil erosion levels and agricultural land values covering five census years (1997, 2002, 2007, 2012, and 2017), we separately investigate the direct effect of two types ...

Comparing hourly climate change projections for hydrology in a Mediterranean meso-scale catchment
Journal of Hydrology: Regional StudiesStudy Region: The 42km2 Claduègne catchment in southern France, under Mediterranean climate is subject to long, dry summers with limited water resources and intense, convective storm events leading to flash floods and overland flow (OF). Study Focus: The

Time-variant snow distribution for use in hydrological models [PDF]
Annals of Glaciology, 2004 AbstractA model is put forward which focuses on the dynamical evolution of the spatial distribution of snow water equivalent (SWE). We make use of the fact that when the accumulation and ablation process of the snow reservoir is modelled as a summation of a gamma-distributed variable, both skewed distributions, typical of alpine areas, and more normal ...

American Journal of Agricultural Economics, EarlyView.Abstract Crop insurance is undoubtedly an extremely valuable element in protecting agricultural businesses, but in many cases standard indemnity‐based products have had very low uptake due to high transaction costs elevating premiums to unaffordable levels.
