United Nations University – Institute for Water, Environment and Health

The volumes of wastewater generated by domestic, municipal, and commercial sources have increased with population, urbanization, improved living conditions, and economic development. The use of wastewater has also increased, as millions of small-scale farmers in urban and peri-urban areas of developing countries depend on wastewater or wastewater-mixed water sources to irrigate crops for urban markets, often as they have no alternative sources of irrigation water. If used in untreated, inadequately treated or diluted forms, the undesirable constituents in wastewater can harm human health and the environment. Hence, wastewater irrigation is an issue of concern to public agencies responsible for maintaining public health and environmental quality.

The good news is that a paradigm shift is currently underway to a proactive interest in recovering water, nutrients and energy from waste streams. This webinar will undertake situation analysis about wastewater management in developing countries, highlight the potential of wastewater as a water, nutrients and energy resource, and address key challenges and opportunities in transforming wastewater as a valuable resource for a range of stakeholders.

The United Nations University Institute for Water, Environment and Health (UNU-INWEH) is a member of the United Nations University family of organizations. It is the United Nations Think Tank on Water created by the UNU Governing Council in 1996. The vision of the institute is a world free of water problems where sustainable human development and environmental health and security are assured for all. The mission is to help resolve pressing water challenges that are of concern to the United Nations, its Member States, and their people, through knowledge-based synthesis of existing bodies of scientific discovery; through cutting edge targeted research that identifies emerging policy issues; through application of on-the ground scalable solutions based on credible research; and, through relevant and targeted public outreach.

UNU-INWEH’s core functions are derived from its mission, apply to all projects and activities, and are designed and fully integrated to maximize impact within the Institute’s vision. Implementation of these interconnected core functions is fully integrated within each of UNU-INWEH’s programme activities, and designed to mutually reinforce and maximize future impact.
