“…While South Africa came second based on the information in Fig. 8, it has also been noted in various studies that South Africa is experiencing drought occurrence in recent years (Walz et al 2018;Orimoloye et al 2019;Adedeji et al 2020).…”

“…In recent times, the debilitating impact of climate change is felt by the increase in drought and unpredictability of water quality sustenance globally (Boakye and Akpor 2011;Olusola et al 2017;Fashae et al 2017;Orimoloye et al 2019;Singh and Sharma 2019;Adedeji et al 2020). Considering the critical situation and circumstance created by drought in line with the shortage in water supplies, this study aims to explore the rich tapestry of studies on drought disasters, drought vulnerability, drought severity and water shortage (DDVS_WS).…”

This study aimed to explore the rich tapestry of studies on drought disasters, drought vulnerability, drought severity and water shortage (DDVS_WS), taking into account the critical situation and circumstance posed by drought in line with the shortage in water supplies. In total, 1117 original articles were downloaded in a BibTeX format for further analysis. The downloaded information included, but was not limited to authors, title, year of publication, citations, author keywords, keywords plus, countries of publications, institutions, journals, citations. Published studies on DDVS_WS obtained from the web of science (WOS) and Scopus databases on 20 May 2020 were used in this study. The field of DDVS_WS experienced a drastic increase with an annual growth of about 12.7% in terms of continued publications output during the years under assessment. Considering the country level, China ranked first with the highest number of publications, and the USA has great academic influence with most top articles' citations emerging from the USA affiliated institutions and research centres. Based on the top keyword, drought and climate change are at the centre of issues related to drought and water shortage, this provides a hint on the relatedness of drought and climate change for further studies. This study offers a map to navigate the intellectual quandary of DDVS_WS research and guidance for further studies in this area of specialization. It is fundamental to stress that this study only covers the core area of DDVS_WS research, hence, it is expected that new empirical studies and potential solutions would offer new insight on drought and water shortage as new research evolves.

“…They calculated low and high-risk areas and their association with agricultural lands. Adedeji et al [19] assessed the spatiotemporal variation of droughts in Nigeria using remote sensing and geographic information system techniques to find regions prone to droughts risk. Jincy Rose and Chitra [20] employed SPI and the Standardized Precipitation Evapotranspiration Index (SPEI) drought indices to evaluate the temporal variation of drought in an Indian River basin.…”

Drought characterization and risk assessment are of great significance due to drought’s negative impact on human health, economy, and ecosystem. This paper investigates drought characterization and risk assessment in the Lempa River basin in Central America. We applied the Standardized Evapotranspiration Deficit Index (SEDI) for drought characterization and drought hazard index (DHI) calculation. Although SEDI’s applicability is theoretically proven, it has been rarely applied. Drought risk is generally derived from the interactions between drought hazard (DHI) and vulnerability (DVI) indices but neglects resilience’s inherent impact. Accordingly, we propose incorporating DHI, DVI, and drought resilience index (DREI) to calculate drought risk index (DRI). Since system factors are not equally vulnerable, i.e., they are heterogeneous, our methodology applies the Analytic Hierarchy Process (AHP) to find the weights of the selected factors for the DVI computation. Finally, we propose a geometric mean method for DRI calculation. Results show a rise in DHI during 2006–2010 that affected DRI. We depict the applicability of SEDI via its relationship with El Nino-La Nina and El Salvador’s cereal production. This research provides a systematic drought risk assessment approach that is useful for decision-makers to allocate resources more smartly or intervene in Drought Risk Reduction (DRR). This research is also useful for those interested in socioeconomic drought.

“…Without a doubt, societies need water, however, water scarcity and quality due to climate change and other factors are threatening food security and other water-reliant sectors around the world [1][2][3]. Adapting to climate change helps reduce the risk of water-related disasters such as droughts and floods.…”

“…The population of the most vulnerable regions, particularly the poorer areas where land and water supplies are already limited, need to be better prepared for potential droughts by reducing and adjusting risks and increasing resistance to droughts. The way drought is monitored and managed has been modified in studies and numerous recent international and regional initiatives [2,4]. Historically, drought has been regarded as a natural hazard that society reacts to with a reactive approach.…”

Ecosystem services refer to the direct and indirect benefits to humanity from an ecosystem. The ability to spatially incorporate multiple biophysical environments is crucial to ecosystem services, thus promoting cooperation between science and policy in seeking solutions to global challenges, including drought disasters. Therefore, understanding ecosystem services, for instance, from forest/vegetation in view of contributing to drought disaster risk adaptation is critical to human-nature interactions and proper sustainable conservation thereof. No known study has been done on ecosystem services and their contributions to drought management or other climate adaptation in South Africa. This study aimed at quantifying drought disaster risk adaptation based on ecosystem services in South Africa. It was identified that ecosystem services to society have been directly affected by anthropogenic and natural phenomena, thereby influencing drought severity and its impacts. These impacts and their associated risks are evident globally, including in South Africa. We found out that ecosystems in South Africa have been affected and extremely vulnerable to recurrent natural disasters, such as droughts. To achieve long-term solutions to such drought-related risks and challenges, feedback mechanisms between human-natural and related factors and ecosystem services-based drought adaptation need to be understood and planned. Timely spatiotemporal assessment, planning and management strategies need to be considered to find solutions or ways forward to South Africa in combating drought disasters.
