Special Issue "Global Changes in Drought Frequency and Severity"
Deadline for manuscript submissions: 30 December 2019.
Drought is often considered as a natural hazard similar to floods, heatwaves, and windstorms. However, with its many definitions and the overall difficulty in estimating its onset, duration, and impacts, more and more analyses and investigations are needed in order to improve the state-of-art of global trends in drought.
This Special Issue calls for contributions on drought frequency and severity, at both a global and continental (or macro-regional) scale. This Issue welcomes original studies on meteorological, hydrological, agricultural, ecological, and socio-economic drought. The single studies can be based on known indicators or new ones can be proposed. Particular attention to the input data quality is recommended. Exceptionally, reviews of the current methodologies to analyze drought trends can be accepted.
Also, studies on single extreme drought events can fit the scopes of this Special Issue, especially if the record-breaking drought events are compared with regional or global events. We also encourage the possible contributors to submit papers dealing with drought risk, with an eye on impacts and socio-economic consequences of droughts.
The results should be presented in tables and high-quality maps, but also interactive material will be considered. Please, avoid very long papers and prioritize the original outputs.

1. Global Drought HAS NOT Intensified and Expanded during 40-year (1980-2019) Strong Climate Warming

Abstract: Following the 2014 report of the International Panel on Climate Change (IPCC), Earth surface (at 2 m high, further indicated as Earth only) climate has been warming up since the mid-18th century. From the late 1970s, Earth warmed up intensively, leading to unusual environmental, economic and social events. Climate publications have indicated that from the second half of 19th century, intensive Earth warming has speeded up ice melting and sea level rise, increased water shortage and drought intensity, deteriorated agricultural system and produced other changes. The experts from the United Nations are warning that continuation of climate warming would strongly intensify and expand droughts, leading to a reduction of crop production, especially in developing countries of Africa, Asia and Latin America, further deteriorating food security and intensifying poor population’s malnutrition and hunger. Since climate warming is continuing, it is important to estimate long-term interaction between global warming and high-resolution drought tendencies, since drought intensification and expansion would strongly deteriorate global food security. This paper develops and investigates satellite-derived 40-year high-resolution drought trends, during the period of intensive Earth warming. Specifically, the paper (a) derives global and regional droughts from NOAA operational satellites (b) analyzes dynamics of drought area and intensity and derives statistical trend, (c) determines if drought intensified and expanded following strong global warming, and (d) predicts anticipated food security. Important that (1) the new satellite-based Vegetation Health (VH) method was used for drought detection and evaluation of intensity and area from vegetation’s thermal-moisture conditions, (2) assessments were done for the entire world and the main grain countries, (3) VH data had 1, 4 and 16 km2 areal and one-week temporal resolution during 1980-2019 and were processed comprehensively. The results indicated that global, hemispheric and the main grain countries’ (China, USA and India) drought trends remained generally stable, while global temperature anomaly has strongly increased between 1980 and 2018. Since drought has not intensified and expanded during the investigated 40 years, while global mean surface temperature anomaly increased almost 1°C, food security in the next few years would remained at the level of the most recent decade.
