PODCAST is a research project under the multinational initiative Towards a sustainable earth (TaSE) implemented with the goal of Human-Environment interactions and sustainable development goals. PODCAST aims to use remote sensing techniques to study the reservoirs of cholera pathogens in the coastal waters of India.Cholera is one of the major public health threats that has been reported to affect 1.3 to 4 million people each year worldwide, with 21,000 to 143,000 reported fatalities. Cholera is a debilitating and often fatal disease that the World Health Organization (WHO) aspires to eradicate by 2030. It is a disease of disadvantaged people that impede economic growth and societal well-being by placing a chronic and widespread burden on the health of those living in susceptible areas. The majority of the disease outbreaks are reported to start in coastal regions from where they spread to the inland regions. Coastal areas of India by virtue of seasonally reversing monsoon winds, and by the seasonally varying inflows from rivers are prone to water-associated diseases. In the PODCAST project, scientists from India, Japan, and the UK work collaboratively to</p><p>1) identify environmental reservoirs of Vibrio cholerae as well as possible advective transport via ocean currents and long-distance transmission routes for cholera outbreaks</p><p>2) characterize the influence of climate perturbations on cholera outbreaks and environmental transmission routes</p><p>3) build an epidemiological model integrating environmental and human-to-human transmission routes</p><p>4) produce forecasts for cholera outbreaks in coastal regions
