A crash course in changing the world.
Describe the biggest challenge to food security in your own local community or country -- and an innovative solution that is already underway.
In my country, many people are cultivators, I advise them to do a system called closing the loop.
Let me explain "Closing the loop" here: In Ecological Sanitation, when people talk about "closing the loop", they mean closing the loop between sanitation and agriculture (chiefly with respect to returning nutrients and organic matter contained in excreta back to the soil).
Make sure: The idea is to fertiliser the soil, not the plant.The plant roots will get the nitrogen from the urine via the soil.
Urine is a complete fertiliser, if you urinate directly on a
plant, urine may have a detrimental
effect on the leaves and flowers of plants.
My thanks to all who want to know and to use "closing the loop".

Hi Lyamuremye,
Thanks for the post. What do you mean by "closing the loop?"

We should close every loop, at least those regarding non-renewable resources, not only the one regarding organic waste (which seems the easier and most logical). I think that's the first step (certainly an important one), but sooner or later non-renewable resources would get harder to get so reciclying is important as a second step of closing the loop.
+1 point from bring such an important point

I just want to add as an example to follow, how ecosystems are always build around organisms "closing loops" (I mean using some not used energy or nutrient (waste for someone else))

Closing the loop refers to returning nutrients from excreta to the soil

This is an important distinction. Most farmers nowdays just use chemical fertilizers, that, while more effective, are a limited resource.
Here in Israel, phosphates harvesting have destroyed some beautiful areas in the Judean desert, and nitrate harvesting is slowly draining away our unique natural resource, the Dead Sea.
If only farmers, even in developed countries, remembered to make use of the nutrients found in our waste excrement, we could greatly reduce the world's dependency on chemical fertilizers.
