Nearly a billion people in the world lack access to safe drinking water, two billion have inadequate sanitation facilities, and three billion use biomass for their daily energy needs.
Combined, these resource limitations are among the leading causes of death, and economic and political insecurity. Exacerbating these problems are the international effects of climate change, expected to significantly impact developing countries by changing water and energy quality and availability.
At Portland State, the SweetLab develops and implements cellular and satellite based "Internet of Things" sensor technologies designed to improve the collection of, and action on, data in global health programs. We deploy and study high efficiency cookstoves, water pumps, household water filters, sanitation systems, pedestrian footbridges and other developing world appropriate technologies. The SweetLab has projects in India, Nepal, Indonesia, the Philippines, Rwanda, Kenya, Uganda, Ethiopia, Haiti and other countries.
We are also engaged in applied unmanned aerial vehicle research, developing and conducting autonomous environmental impact assessments domestically and internationally with drone-derived imagery. Similar to our sensor work, drone-derived image analysis has enabled us to increase data collection in data-scarce regions in developing countries, allowing us and our partners to actively respond to environmental and human health risks including deforestation and air and water quality measures.
Our research and practice has been funded by the National Science Foundation (NSF), the World Bank, the United States Agency for International Development (USAID), the United Nations Foundation, the United States Centers for Disease Control and Prevention (CDC), the United Kingdom Department for International Development (UK DFID), the Gates Foundation, and others.
