“…A run is defined as a portion of the time series of a drought variable, in which all values are either below or above the selected truncation level; accordingly, it is called either a negative run or a positive run [5]. In runs theory, drought intensity is the average value of a drought parameter below the threshold level, which is measured as the drought severity divided by the duration [36]. In this study, we set SPEI of −1 as the threshold value for identifying drought conditions, with SPEIs below −1 being used to estimate drought intensity.…”

Abstract:The aim of this study is to analyze the characteristics of drought, such as intensity and trends, based on SPEI (Standardized Precipitation Evapotranspiration Index) at 8 stations in South Korea from 1981 to 2010. The traditional SPEI is based on the Thornthwaite equation for estimating evapotranspiration; SPEI_th. However, a standard of agricultural water management in Korea suggests the FAO Penman-Monteith equation; SPEI_pm. Therefore, we analyzed the intensity, variability, and trends of drought using SPEI_th and SPEI_pm, respectively, and compared the results. SPEI_pm showed slightly more intensive drought rather than SPEI_th except for Chuncheon and Gwangju. In 5 stations-excluding Cheoncheon, Gwangju and Jinju-the cumulative probability that SPEI_pm was below −1.5 was significantly increased from 1981-1995 to 1996-2010. In addition, the northwest and southwest regions had higher intensity of 1-month droughts, and the central and southwest regions had a higher intensity of 3-month droughts. According to the Mann-Kendall test, there was a decreasing trend of 1-month SPEI during the fall season and 3-month SPEI during winter season.

“…It has been frequently used on time series of irregular hydrologic events to identify drought components and investigate their statistical properties [21], [22]. A -run‖ is defined as a portion of time series of the variable that is less than the chosen threshold [23], [24]. Following Nalbantis and Tsakiris [18], the drought event in this study is defined as the period where SDI values are less than the threshold value of zero.…”

Drought's frequency, duration and severity are essentials for impact control and mitigation of droughts. This paper adopts 3-month seasonal scale Streamflow Drought Index (SDI-3) to analyze these drought characteristics for the tropical climate at the Central, Southern and East Coast regions of Peninsular Malaysia in 1997-2016. The identified drought events were then evaluated using four major historical events from five different locations. The results showed that SDI-3 identified the occurrences of all reported drought events but with deviated onset and duration. However, the SDI-3 was concluded to be suitable for hydrological drought monitoring with reasons of increased temperature, groundwater and forest replenishment, and human factors. The spatial analysis on the drought characteristics also showed that most of the areas are more prone to short-term droughts, with relatively higher severity at north part of the Central Region, north-west part of the Southern Region and central part of the East Coast.

“…However, the same authors state that these results are strongly dependent on simulations from only one set of climate change data. There are therefore limitations due to the uncertainty in various climate change scenarios [16]. Zhou et al (2017) studied the future effects of climate change on crop irrigation requirement in the Hetao irrigation district, China.…”

“…Only two studies [9,11] identify, propose, discuss, and develop an adaptation scenario. Five other studies [10,14,[16][17][18] belong more properly to the category "Climate change impact studies". The last three studies [24][25][26] analyze changes that have occurred in the climate and with water resources in the recent past decades, without developing any future scenarios.…”

Abstract:The Paris Agreement presents new fields of research related to the adaptation strategies to climate change. A challenge for future research consists in developing context-specific guidelines to support adaptation. This Special Issue on "Adaptation strategy to climate change for water resources" is born in this context. It contains 15 scientific studies facing a diversity of issues inherent to the adaptation strategies for water resources. This editorial analyses how the authors of this collection of papers decided to develop and present their research in order to identify criteria to contribute defining, in a near future, standardized approaches and practices for adaptation studies. Papers have been categorized in two major fields: "Studies for the development of adaptation scenarios" and "Studies for the development of adaptation solutions". Papers belonging to both categories are generally found missing to treat the 'uncertainty' issues arising and the implementation of the proposed adaptation strategies. Studies investigating future adaptation scenarios are generally found to be unbalanced in favor of the assessment of future impacts on water resources and less towards the provision of adaptation scenarios. When these studies do not provide elements to manage the specific uncertainty related to the proposed adaptation solutions, at least exploring the uncertainty related to the climatic and impact scenarios is strongly recommended. Studies providing methodological and/or procedural examinations on adaptation solutions are recommended to suitably report the climatic, environmental, and social context for which the action has been developed. A reduction of uncertainty and an easier implementation of proposed measures could be induced from this.
