The papers selected for publication include review papers on water history, on water management issues under water scarcity regimes, on rainwater harvesting, on water quality and degradation, and on climatic variability impacts on water resources. Overall, the issue underscores the need for a revised water management, especially in areas with demographic change and climate vulnerability towards sustainable and secure water supply. Moreover, general guidelines and possible solutions, such as the adoption of advanced technological solutions and practices that improve water use efficiency and the use of alternative (non-conventional) water resources are highlighted and discussed to address growing environmental and health issues and to reduce the emerging conflicts among water users.<\/jats:p>","DOI":"10.3390\/w12092347","type":"journal-article","created":{"date-parts":[[2020,8,23]],"date-time":"2020-08-23T22:10:14Z","timestamp":1598220614000},"page":"2347","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":378,"title":["Water Supply and Water Scarcity"],"prefix":"10.3390","volume":"12","author":[{"given":"Vasileios A.","family":"Tzanakakis","sequence":"first","affiliation":[{"name":"Department of Agriculture, School of Agricultural Science, Hellenic Mediterranean University, Iraklion, 71410 Crete, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikolaos V.","family":"Paranychianakis","sequence":"additional","affiliation":[{"name":"School of Environmental Engineering, Technical University of Crete, 73100 Chania, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3073-596X","authenticated-orcid":false,"given":"Andreas N.","family":"Angelakis","sequence":"additional","affiliation":[{"name":"Hellenic Agricultural Organization (HAO)-Demeter, Agricultural Research Institution of Crete, 71300 Iraklion, Greece"},{"name":"Union of Hellenic Water Supply and Sewerage Operators, 41222 Larissa, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"238","DOI":"10.1126\/science.abb6902","article-title":"Anthropogenic megadrought","volume":"368","author":"Stahle","year":"2020","journal-title":"Science"},{"key":"ref_2","unstructured":"Smith, K.
