Infinitum Humanitarian Systems (IHS) is a Washington State company specializing in vulnerability reduction for systems and populations. We work with a range of partners to analyze the disaster risks within informal settlements in the developing world and we assist governments and communities with mitigation strategies for those at greatest risk. We work closely with both public and private sector interests to reduce the impact of industrial and natural disasters using geospatial information, taxonomic data management, system dynamics, complex adaptive systems visualization, public health epidemiology, water reclamation, industrial waste re-purposing, and a participatory educational process based on free and open-source tools. We have designed and installed a number of unique water purification systems and several now serve as small businesses for the urban poor. We contribute to open GIS data efforts globally, and we stress clean, fair, responsible, and sustainable manufacturing and procurement processes with our several partners. We also lead the Global Disaster Response Team for the Roddenberry Foundation, the philanthropic arm of the Star Trek franchise. Urban disaster resilience is our core focus at IHS. Natural and industrial hazards are often unavoidable, but we can reduce the impact that makes them "disasters". Our project teams work with governments around the world at national, regional and community levels to provide both strategic and practical recommendations for understanding risk and strengthening the infrastructure needed for human security, particularly in slums. We use the term "human security" carefully. In contrast to national security, the focus of human security is the safety and well-being of individuals and the communities they form, regardless of their location, nationality, religion, race, politics, sexual orientation, or social standing.
