Coastal areas are at the nexus of land, water, and biodiversity. While being a productive ecosystem in terms of materials, energy, and organisms, growing population and natural and anthropogenic disasters make them a vulnerable system, especially in the context of climate change and sea level rise. Continued rapid urbanization in coastal areas leads to dramatic changes in the environment in general and marine ecosystems and biodiversity, riverine and estuarine wetlands, water quality and quantity in particular. It has been become an urgent but complex issue to assess, monitor, and analyze coastal environments and human-environment interactions along coastal zones due to the complex relationship between social and economic development, population growth, and climate change. Remote sensing, GIS, and other geospatial technologies, as enabling methods and techniques, have been widely applied in the past decades to address issues pertaining to urbanization, coastal vulnerability, and sustainability. Group on Earth Observations have developed numerous programs and initiatives since 2012 (e.g., Global Urban Observation and Information Initiative) to coordinate the activities of participating organizations and countries to cope with these environmental and societal challenges. Numerous user engagement efforts have been made to facilitate the dissemination of EO-based data products, models, systems, tools, and services in support of the UN’s Sustainable Development Goals.
This is the fifth year we utilize AAG annual meeting as the platform for a symposium. By organizing this event, it is hoped to create an opportunity for intensive discussions about various pertinent issues on coastal vulnerability, urbanization, and sustainability, to provide stimulations to interested students and young researchers to join the GEO initiatives and activities, and to foster remote sensing and geospatial research. In 2019, we especially welcome paper presentations, regardless theoretical analysis, empirical studies, modeling, or in situ observations, to address the following topics:
• Benefits of remote sensing for coastal studies;
• Coastal water and wetland resources;
• EO-based urban variables and indicators to support sustainable cities;
• Urban infrastructures (impervious surfaces, roads, buildings) and urban hazards;
• Coastal hazards, vulnerability, and resilience to extreme weather events;
• Ecosystem structures and functions of cities and their hinterlands in the coastal regions;
• Urbanizing deltas and environmental impacts;
• Integration of EO with in situ data as well as social media and big data.
