Water shortage risk mapping: a GIS-MCDA approach for a medium-sized city in the Brazilian semi-arid region

Feasibility, seasonality and reliability of rainwater harvesting in buildings of a university in Campina Grande, Paraíba

“…According to its distribution plan, approximately 68% of total monthly uses correspond to public supply (Agência Nacional de Águas e Saneamento Básico, 2020b). In the last two decades, this water body has gone through two critical periods in water supply (Figure 3), the second almost causing the collapse of the public supply service in 2017 (Rêgo et al, 2017;Cordão et al, 2020). This history shows the need to discuss ways to partially decentralize water supply, with alternative sources of water.…”

A composite indicator index as a proxy for measuring the quality of water supply as perceived by users for urban water services

“…This methodology has been used in studies of efficiency/inefficiency (Al-Assa'd and Sauer, 2010;Romano and Guerrini, 2011;Kulshrestha and Vishwakarma, 2013;Ananda, 2014;Molinos-Senante et al, 2018;Ablanedo-Rosas et al, 2020), eco-efficiency/sustainable efficiency (Molinos-Senante et al, 2016a;Gémar et al, 2018;Lombardi et al, 2019;Delgado-Antequera et al, 2021), sector regulation efficiency (Cabrera Jr et al, 2018), service ownership (García-Sánchez, 2006;Munisamy, 2009;Lo Storto, 2013;Suárez-Varela et al, 2017), the effects of (structural) sector reforms on efficiency and productivity (Abbott et al, 2012;Ferreira da Cruz et al, 2012), growth of the efficiency/productivity of utilities in water supply (Nyathikala and Kulshrestha, 2017), and the quality of the service provided to customers in terms of efficiency (Woodbury and Dollery, 2004;Kumar and Managi, 2010;Molinos-Senante et al, 2016c;Maziotis et al, 2017). MCDA has been used in water resources management (Calizaya et al, 2010;Amorocho-Daza et al, 2019;Bera and Banik, 2019;Psomas et al, 2021) and in the management of urban water supply (Lai et al, 2008;Carriço et al, 2012;Cordão et al, 2020;Cunha et al, 2020). For details on the use of MCDA in sustainability, see Goyal et al (2020).…”

Study On The Causes Of Coal Mine Production Safety Risks

“…This theory can serve as a basis for solving complex problems as well as analyzing and studying problems from three dimensions. WSR theory is widely applied in risk management 8,9 , urban construction 10,11,12 , enterprise management, 13,14 and coal mining. The theory can be applied to the establishment of a risk index system of coal mine production safety.…”
