Learn about the best environmental technologies for a sustainable development and how they are managed in various settings around the world. This course gives you an opportunity to learn about global trends that influence our environment and the living conditions and how different management systems and approaches that are used around the world to manage the environment. This includes current environmental technologies built for the environment and technologies for sustainable soil management, groundwater protection methods and integrated Water resources management.
From the lesson
WEEK/MODULE 4: Technologies for the Built Environment
In week 4 we look at some of the current environmental technologies that are particularly effective in carrying out their purpose and in an environmental friendly way. We look at how we choose among different technologies and study storm water technologies, urban water supply and solid waste handling.
