"I love that you've brought this to attention. An extensive database of uncommon but resistant and hardy plants/foods could be developed and organized by climate. Ease of growth and processing should also be taken in to account. I will try to…"
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".

Very important idea here. We sometimes see the use of composting toilets that also allow for this in a sanitary yet nutritious way for the soil. Are there many countries that are making their own flow systems to close the loop?

Great post. There's been some discussion on this already, particularly about the difficulties of implementing this in the developed world where hormones, antibiotics, and preservatives make it into the waste stream. Ironically, developing countries will have a much better time implementing these types of solutions...

For sure, I studied a course of Ecological Sanitation at UNESCO-IHE institute for water education in Netherlands, even there they use this system. South Africa, Rwanda, Burundi, ...

It's interesting to hear how "closing the loop" means different things in different contexts. In the West, it's often about using local resources to keep transportation costs lower, or creating new products with recycled materials to keep them out of the waste stream. Whether it's about growing plants or making stuff, I guess it's all about keeping the cycle going.

Fourth of July on the Lake
This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More
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. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

Future
FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out.

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
