Advances in modeling and early warning systems have led to many successful transdisciplinary collaborations among geoscientists, health professionals and social scientists to better understand risk factors, population vulnerabilities, and public health impacts due to ongoing changes in climate and the environment. The barriers to access to technological advancements, new techniques and tools, in conjunction with limitations of dissemination efforts in resource constrained regions around the globe, affect high stakes, urgent societal decisions and outcomes related to poverty, inequity and health. This session focuses on the development of innovative dissemination approaches and advances in risk communication for infectious diseases that are influenced by changes in the environment and climatic patterns. One major focus of the session will be to highlight new approaches and emerging technologies that address issues of poverty, inequity and health, and aim at the sustained use of geospatial modeling and early warning systems by at risk, marginalized populations.
