DATA SERVICES CORE ABSTRACT The Data Services Core (DSC) of the proposed Global Center on Climate Change and Water, Energy, Food and Health (GC3WEFH) will provide data and computational support for the research project team of the GC3WEFH and for other related center activities, including advanced research addressing research questions, training, and community engagement. Capacity-building efforts with respect to data collection, data analysis, and visualization will be designed to help the health research community and NGOs in Jordan in informed decision-making and to ensure the sustainability and scalability of the model developments achieved during this exploratory phase of the GC3WEFH. The team assembled has deep expertise in relevant work, access to needed data, and a track record of achieving research aims of impact on time. To support the GC3WEFH in its overall mission of addressing climate change health impacts among the most vulnerable global communities, the DSC will focus on the following specific aims and tasks: 1) Data Hub: Organize available data into a searchable online catalog of curated datasets with comprehensive metadata and provenance information, ready for analysis of interactions in the water-food-energy-health (WEFH) nexus in Jordan. 2) Capacity building and training: Build capacity of our partners in Jordan by developing advanced data management and data science research curriculum materials on local WEFH themes, particularly data collection, mapping, and spatial analysis and modeling, and delivering the curriculum through online webinars and in-person workshops in Jordan. 3) Technical assistance to the Research Project Core: Support Center scientists with technical assistance in data and spatial analyses and mapping to minimize time from data collection and management to research. 4) Data collection, broad community engagement, and policy advancement: Collaborate with the Community Engagement Core to establish the DSC as a resource for additional project stakeholders, including partnering community organizations, the Ministry of Health, the Higher Council for Science and Technology (HCST), and the Royal Scientific Society, to translate the collected information and scientific insights into behaviors, policies, and actions to address climate change health impacts in the Azraq Basin area of Jordan.
