This course may seem a bit off the topic: up until now, we have been talking about sanitation, and actually mainly about excreta management. Yet, when people are interested in providing a sustainable sanitation solution, they are typically also looking for sustainable water services. Moreover, a lack of proper water supply or a water shortage can be a very good reason to look for ecosan solutions, and then these WDM aspects come in very handy. The third link between WDM and ecosan is that ecosan is focused on closing the loop, reusing the nutrients in agriculture. For sustainable agriculture, a renewable water source is essential. And finally, preventing the production of extra wastewater or the loss of clean water fits of course perfectly within the concept of ecological and sustainable sanitation.
The slides look a bit different from what you are used to: they were made by my colleague Saroj Sharma. They have an icon on almost each slide, showing a loudspeaker. If you click on it, and you have your sound system switched on, you hear the voice of Saroj explaining the message on the slide in a little bit more detail. Saroj is a very well-known researcher in his area, and he takes great pleasure in the topic and in the interaction with the students. So, please so not hesitate to contact him in case you have any questions!
