A new calculation method is discussed, which provides early information on physical implementation of drought risk levels and improvement in setting up a complex drought monitoring system, which could assist hydrologists, meteorologists and farmers to predict and more precisely quantify the yield loss and the role of vegetation in the hydrological cycle. Drought 58. [emailprotected], Editors: Mannava V.K. A new agricultural drought index for monitoring the water Keywords: The DIs that best corelated with CIs were those that included temperature in their calculations (STCI, SVHI, and SPEI). Drought, one of the most destructive natural disasters is projected by numerous studies to become more severe and widespread under climate change. The Crop Moisture Index (CMI) gives the short-term or current status of purely agricultural drought or moisture surplus and can change rapidly from week to week. Tunnelling and Underground Space Technology, An agricultural drought is considered to have set in when the soil moisture availability to plants has dropped to such a level that it adversely affects the crop yield and hence agricultural profitability. A drought indicator reflecting ecosystem responses to water availability: The Normalized Ecosystem Drought Index. Keywords: A new agricultural drought index was developed for monitoring drought impacts on agriculture in Oklahoma. Accessibility However, the characteristics of agricultural drought in China have not been well understood. This study presents a benchmark of eight DIs and 19 large-scale climate indices (CIs) to monitor agricultural drought in Argentina.
