Comparative Assessment of Machine Learning and Statistical Models for Agricultural Drought Forecasting and Driver Attribution in the North China Plain

ABSTRACT Drought severely threatens agricultural productivity and water resources in the North China Plain (NCP). This study provides a spatiotemporal analysis and prediction of agricultural drought from 2001 to 2024 using the Vegetation Health Index (VHI) derived from satellite...

Identifying Controlling Climate Factors Conducive to Water and Nitrogen Export from an Agricultural Watershed During the Snowmelt Runoff Period Using the SWAT Model

Abstract. Temperature and precipitation variations during the freezing-thawing period affect snowmelt and accompanying nitrogen export in a complex manner. These influences can be long-lasting, superimposed, and strengthened. Daily discharge and nitrate nitrogen NO3--N concentrat...
