Communication with Hazard Maps in Central America: A multidisciplinary science-media-community network (HazMap_CA) Countries along the Pacific coast of Central America are exposed to high environmental risk from earthquakes, volcanic activity, tsunamis, meteorological hazards and landslides. Over the past two decades, disasters in El Salvador, Guatemala, and Nicaragua alone have caused over US$9 billion in damage and affected more than 13.5 million people. Their exposure to these environmental hazards and their vulnerability to being adversely affected by them are exacerbated as a result of both the complex socio-political setting and approaches used in those countries for economic development.  Information about hazards and disasters is very commonly disseminated through maps. Hazard maps that are useful, usable and used have the potential to prevent disasters and build societal resilience. Although maps represent the important outward face of hazard research, they are cartographic representations of inherently complex information, with large associated uncertainties. Further, the effective understanding, perception, experience and usage of maps calls for multidisciplinary engagement. This proposal will bring together and form, for the first time, a network of researchers and practitioners to understand how hazard maps can be used more effectively to communicate hazard information with decision makers, emergency managers, NGOs, and the public before, during and after times of crisis.   The challenges that need to be addressed in doing this demand input from diverse groups, including academic researchers and practitioners and stakeholder groups. Further, while knowledge informed by Western scientific approaches has an extremely important role to play in hazard and disaster management, its utility remains limited if it is not brought into a meaningful dialogue with alternative approaches and understandings. Our intention is therefore to create a network that brings together expertise from natural sciences, cartography, visual geographies, landscape perception, media and communication studies and Central American development studies to facilitate engagement between disciplines that would not normally interact. In combination these can produce a more detailed and multifaceted understanding of how maps are used to convey hazards associated with the landscape. The network will involve bringing together existing, yet separate, working groups who are actively engaged in initiatives to address development and disaster preparedness in Central America. This will be facilitated through two workshops, one in the UK and one in Central America.   Our central aim is to address developmental issues in the region by strengthening existing emergency management systems and creating useful modes of hazard communication that empower communities, enhance the effectiveness of communication and increase resilience. The Global Challenges Research Fund (GCRF) supports cutting-edge research to address challenges faced by developing countries. The fund addresses the UN sustainable development goals. It aims to maximise the impact of research and innovation to improve lives and opportunity in the developing world.
