Key stressors like climate change and water scarcity can limit biodiversity and economic activities in entire regions. One example will be intermittency in water flow with implications for hydrologic connectivity, negative side effects on biodiversity, water quality, and river ecosystem functioning. Water scarcity can amplify the effects of water pollution by reducing the natural diluting capacity of rivers. Interactions between stressors may be exacerbated by climate change. \nWater Scarcity and Climate Change are going hand in hand in most cases. The relevance of water scarcity as a stressor is most important in semi-arid regions such as the Mediterranean basin, characterised by highly variable river flows and the periodic occurrence of low flows and even no-flows. Climate change previsions forecast an increase in the frequency and magnitude of extreme events. Although extremes are part of the normal hydrologic behaviour in Mediterranean-type rivers, many already show a consistent trend towards decreased discharge. In this respect, the Mediterranean basin is one of the most prominent \u2018\u2018hot spots\u201d for potential changes in water availability. Most climate change models conclude that Mediterranean regions will be more affected by summer drought, higher flood frequency and higher temperatures. These changes will probably not be limited to catchments draining into the Mediterranean Sea but will affect all Mediterranean-type regions worldwide, like certain parts of California and Australia, among others.\nThis presentation will describe in the first part the main threats associated with climate change related to global warming and temperature increase around the planet. Strategies for mitigation and adaptation to climate change with a focus on capturing greenhouse gases (GHG) will be reported. Among them, afforestation and carbon neutrality using phytocapture with algae, as well as the use of biochar for environmental remediation and GHG reduction, will be mentioned. Examples from the European projects SCARCE and GLOBAQUA on of several river basins: Ebro, Llobregat, Guadalquivir and Juca,r as well as other European rivers like Adige, Evrotas and Sava will be reported (1). As main conclusion of the reconnaissance study in Spain was that pesticides like azoxystrobin, imidacloprid, carbendazim, propiconazole, permethrin and azinphos-ethyl were identified as most toxic to aquatic biota as compared to other chemical groups like pharmaceuticals or industrial pollutants. Water scarcity has increased in general the risk of emerging contaminants presence in rivers. New types of pollutants like antimicrobial resistance genes (ARG) and microplastics (MPs) are expected to be relevant under a climate change scenario. Examples from Europe, China and Saudi Arabia will be presented (2).\nTo overcome pollution problems in rivers under climate change effects, new solutions are required to improve river water quality and quantity, like the use of advanced water treatment options. The thing is that conventional WWTPs were not designed to remove some organic compound,s such as emerging pollutants. A wide array of micropollutants is usually found in WWTP effluents, so there is a need to develop and evaluate alternative treatments which could be efficient for their elimination. In short, several advanced treatments such as membrane bioreactors (MBR), nanofiltration\/ ultrafiltration, reverse osmosis, eco-friendly- technologies like algal-based solutions and advanced oxidation processes like photocatalysis could improve the removal of many emerging pollutants and microplastics, thereby diminishing their presence in surface waters. An overview of the different water treatment technologies with practical examples will be reported (3,4). In the case of Spain, we will report recent examples of water scarcity in the metropolitan area of Barcelona, in the Catalonia region of Spain, where still reservoirs are the main source of drinking water supply. In the last few years, water reuse and desalination technologies have been developed becoming increasingly important in the coming years in order to overcome the permanent problem of water scarcity in this region.\nLastly, by improving the water treatment, the river water will be of better quality an additional source for different reuse options, like agriculture or groundwater recharge, being one of the mitigation strategies against climate change and water scarcity. Direct potable reuse is already being considered in Catalonia, following the steps of California under the new regulation recently published last October 1st, 2024.\n\n\u003C\/div\u003E\n      \u003C\/div\u003E\n  \n  \u003Cdiv class=\u0022mt-5 mb-5\u0022\u003E\n          \u003Cspan\u003E\n          \u003Cb\u003EPresenter:\u003C\/b\u003E\n                      \u003Cp\u003E\n            \u003Ca href=\u0022\/person\/prof-damia-barcelo-culleres\u0022 hreflang=\u0022en\u0022\u003EProf Dami\u00e0 Barcel\u00f3 Culleres\u003C\/a\u003E\n            \u003C\/p\u003E\n                  \u003C\/span\u003E\n      \u003C\/div\u003E\n\n  \u003Cdiv class=\u0022mb-5\u0022\u003E\n          \u003Cdiv class=\u0022field__label\u0022\u003E\n        Author\n      \u003C\/div\u003E\n              \u003Cp\u003E\n          Dami\u00e0  Barcel\u00f3 Culleres\n        \u003C\/p\u003E\n            \u003C\/div\u003E\n\n\u003C\/article\u003E\n","dialogOptions":{"width":"700","position":{"my":"right top","at":"right top"},"closeOnEscape":true,"dialogClass":"presentation-dialog","modal":true,"title":"","classes":{"ui-dialog":"presentation-dialog"}}}]
