The United Nations describes sustainable development as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs." It encompasses the need to incorporate growing concerns about a range of environmental and public health issues with socio-economic affairs. This new book focuses on the goal of implementing greener environment approaches while considering public health and human well-being and economies. The volume presents and examines advances, developments, and the underlying concepts of a healthy urban environment in the areas of water and wastewater treatment, food supply under sustainable development, and chemical contamination.
