“…Accordingly, a threshold of −1 was used for SPI-3, with values below the threshold representing moderate to extreme drought conditions. With respect to VCI, Kogan [57] proposed a threshold of 35% for identifying drought conditions, which has widely been adopted by the drought monitoring community [18,58]. Related to this, we applied the drought classification stated by Klisch and Atzberger [59] for VCI (see Table 2), in which the 35% threshold indicates moderate to extreme drought conditions.…”

“…Numerous studies and approaches dealing with remote sensing-based drought monitoring and with a focus on the African continent have been published. In this connection, operational approaches on global-and continental-scale drought monitoring [6,[17][18][19][20] as well as remote sensing-based studies on droughts in Africa focussing on selected regions and/or periods are to be mentioned. Here, topics of current interest are the ongoing debate on the Sahelian "greening" [21][22][23], drought during 2010/2011 in the Horn of Africa [13,[24][25][26], rainfall and vegetation-related drought dynamics in southern Africa [27][28][29][30], continental-scale drought assessment [12,31,32] as well as the relation between droughts in Africa and ENSO [9,[33][34][35][36].…”

“…A system for drought monitoring and prediction can be a vital tool to facilitate drought response while saving money, time, and lives [134]. Drought indicators can be based on one variable or a combination of variables.…”

“…The National Environmental Satellite, Data, and Information Service (NESDIS) provided the weekly global VHI products generated following a method developed by Kogan (1997). Bai and Di (2012) and Deng et al (2013) reported a Global Agricultural Drought Monitoring and Forecasting System (GADMFS) which is a web-based service system developed for researchers and policy-makers. This paper focuses on the design and performance evaluation of a drought monitoring system, DroughtWatch, developed for monitoring drought conditions in China.…”
