Abstract:



A water shortage risk map in an urban area can be a powerful tool for policy-makers decisions and planning in water scarcity periods. In this approach, a GIS-based MCDA uses eight criteria considering their influence on shortages: Local population (C1), Topography (C2), Distance to the water distribution reservoirs (C3), Distance to Pumping Station (C4), Proximity to the main pipelines (C5), Households supplied by the Water System (C6), Monthly Income (C7) and Land-use (C8). After consulting a group of stakeholders (Experts and Water Supply Company Engineers), an MCDA site-suitability analysis is done using AHP (Analytic hierarchy process) and WLC (Weighted Linear Combination). In collaboration with the Planejee projectat the University of Exeter, a team of young researchers from UFCG (Federal University of Campina Grande, Brazil) conducted by a Ph.D. candidate from UoE/CWS (Centre for Water Systems), collected data from 158 households and validated the risk mapping. All map modeling is running in an ArcGIS environment. This research aggregates several studies in the city of Campina Grande using Geospatial Technologies applied to Water security.



Biography:



Prof. Iana Rufino joined the Natural Resources Center of UFCG in 2006, and is now an Associate Professor. She holds a PhD in Natural Resources (UFCG), an MSc in Architecture and Urbanism (USP), and a Bachelor’s degree in Civil Engineering (UFPB). From 2012 to 2013, Prof. Rufino was an academic visitor at the Center for Geospatial Technology/Texas Tech University in Lubbock, TX (US). From August 2019 to July 2020 she is a researcher visitor at CWS/UoE.

Aa an associate professor, she teaches courses of Applied Geospatial Technologies for graduate and undergraduate students (Civil Engineering, Architecture & Urbanism, Environmental Engineering). She is also a supervisor (Master and Doctorate degrees) and researcher of the IWRM (Integrated Water Resources Management) Group at UFCG, collaborating with many national and international projects.

Her main interests are Geospatial Technologies applied to Water Resources Management in Urban and Regional Areas; Remote Sensing supporting LULCC (Land-use/Land-cover Changes) in semi-arid regions.
