The Arborloo
Sometimes solutions to water problems don't involve water as directly as one might think.
The Arborloo was developed by Peter Morgan, a Zimbabwean and was originally deployed in Ethiopia, but its success has led to it being moved into other African nations.
A pit measuring 80 centimetres deep and 60 centimetres wide is dug, dry leaves are added to the bottom and a concrete slab is placed over the
opening. After each use, a cup of soil and wood ash mixture is added to
encourage composting, reduce smell, and discourage insects. A simple
structure can be added on top for privacy. The toilet is used by a
household for one year, after which the slab is removed, the pit is
topped up with good topsoil, and a fruit tree seedling or other crop is
planted in the topsoil.
Full article is here, and I'm sure that this idea will continue to enjoy tremendous success in the coming years.

Though I don't really see the link with Water Crisis (maybe you should class that blog post on Food security), I find this idea excellent and easy to do. Thanks for sharing :)

Great post and pictures, thank! Edwige, I think the link with the water crisis is that a system of this sort means you no longer have to use gallons of fresh water for sewage disposal. Of course in poorer countries no one uses water for this purpose anyway, but a slightly more sophisticated system is available for developed countries in the form of composting toilets.

Ok, now I see the link ^^ I actually had in mind the actual toilets in Burkina Faso for instance, where there are a lot of insects, and that remain open for a long time without ever planting a tree over it. (but no use of water at all)

Stinging Nettle
In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle.

In addition the Stinging Nettle consists…See More

Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More
