Rastislav Elgr:  Bringing Geology to Everyone through Interactive Web Maps and Open Data Site

Abstract:

In early 2015, the Alberta Geological Survey and Alberta Energy collaborated to create a set of interactive web maps including the Alberta Interactive Minerals Map (AIMM). The main goal of this project was to provide the general public, mineral exploration industry and government easier access to previously published geology and mineral data, in a modern and cost effective way. We used a combination of ESRI’s ArcGIS Online and Open Data technologies to create the interactive web maps and provide easy access to the data directly from the map interfaces.  In this presentation, I showed how we delivered spatial geological information to our stakeholders in a digital interactive format; and I highlighted the advantages over traditional hard copy delivery methods.

Francois-Nicolas Robinne:  More people, more fires, less water: exploring wildfire risks to water security in a changing world.  

Abstract

Recent major fire events (e.g. Horse River Fire, Rim fire) have raised public attention on water quality and quantity issues induced by fire-related changes in the hydrological cycle. Vegetation combustion indeed triggers a range of cascading effects that can greatly enhance runoff-erosion processes, thereby increasing water transport capacities eventually leading to higher downstream flow volumes and pollutant loads. Such alteration of surface water resources may pose a threat to human and natural communities and compromise the provision of a safe drinking-water supply or reliable environmental flows.
Protecting freshwater resources from dangerous situations is at the core of the water security paradigm, although threats emerging after a blaze have not received much interest so far. Despite a large corpus of studies showing the potentially deleterious effects of fire on watershed functioning, research pieces focusing on water supply issues remain too rare and are even inexistent at a global scale.
My work explores the spatial potential for the occurrence of the wildfire-water risk (WWR) at a global scale through the water security lens. I defined the WWR as “the potential for wildfires to adversely affect water resources important for downstream ecosystems and human water needs for adequate water quantity and quality”. I mainly used indexation modelling, a simple method commonly used to represent complex processes and widely applied to global scale studies. My research, as a “flag in the ground”, provides a first worldwide vision of the present and future patterns of the WWR.
