Animals as the Answer to Recycling Food waste

Mountains of food scraps end up in landfills every day. While northern countries glorify attempts to facilitate this trash-to-treasure process using state-of-the-art technologies, Bobbili, a town in Northeast India, adopts a tech-free solution – a park using animals for solid waste management.

Lost Crops of Africa
May 24, 2014 by Filed Under: Books & Reference, Farming, Food, Random
“Like Asia and the Americas, the continent of Africa is blessed with a rich tropical flora. Many of the 50,000 or so plants that evolved within its forests and savannas ripen fruits to tempt the myriad wild creatures into spreading their seeds. Speaking generally, Africa has as many of these tasty morsels as tropical Asia or America.
This fact, however, is something one would never guess by looking in produce markets or college textbooks. Today, American and Asian species dominate tropical fruit production worldwide, including within Africa itself.
For this, there is good reason. Africa’s fruits have not, by and large, been brought up to their potential in terms of quality, production, and availability. Geographically speaking, few have moved beyond Africa’s shores; horticulturally speaking, most remain poorly known. Thus, the vast continental landmass lying between Mauritania and Mauritius contains a cornucopia of horticultural, nutritional, and rural-development jewels still waiting to be cut and polished.”

Precolumbian Causeways and Canals
Detail of an engineered landscape in the Bolivian Amazon. Artwork by Clark Erickson.
“In contrast to the Western obsession to drain what are considered marginal wetlands for agriculture, farmers in the Bolivian Amazon may have intentionally expanded wetlands and wetland productivity through earthwork construction, which impedes, rather than enhances, drainage.
The precolumbian farmers did not use causeways as dikes to prevent inundation of fields and settlements, but rather to expand and enhance inundation for agricultural production.
At the same time, impounding water with well-placed causeways and the creation of canals improved and extended the season of transportation by canoe across the landscape. The grid-like structure also permanently marked land tenure in a highly visible manner.” [Read more…]
Agricultural Heritage Systems
May 7, 2014 by Filed Under: Books & Reference, Farming, Random
Six traditional farming systems in China, Iran and South Korea known for their unique characteristics and approaches to sustainability have been designated Globally Important Agricultural Heritage Systems (GIAHS) by the Food and Agriculture Organization of the United Nations (FAO).
They include Iran’s Qanat Irrigation system, an ancient network of farms that have survived for nearly three millennia; a 22-thousand-kilometer system of black stone walls built from volcanic rock in Jeju, South Korea; and the traditional Gudeuljang Irrigated rice terraces in Cheongsando, South Korea.
Also on the list are a trio of sites in China: the unique Xinghua Duotian Agrosystem, famous for its method of water-land utilization; the historic Jasmine and Tea Culture System of Fuzhou City; and, the Jiaxian Traditional Chinese Date Gardens. The sites were officially recognized during the 28-29 April meeting of the GIAHS Scientific and Steering Committee at FAO headquarters in Rome.
These new designations bring the number of GIAHS systems to a total of 31 sites located in 14 countries in Africa, Latin America and Asia. The sites are considered models of innovation, sustainability and adaptability, delivering important benefits to the ecosystem. The GHIAS website has extensive documentation about most of these agricultural heritage systems. Picture: The Jasmine and Tea Culture System of Fuzhou City, China.
Sharing Stuff without Apps
May 1, 2014 by Filed Under: Consumption, Random
In every household we find tools, appliances and other stuff that are used only occasionally. If these things could be shared among neighbours, we need to buy much less. One way to achieve this is by setting up a hardware library, another way is to design an ‘app’ and use the internet to organize sharing among neighbours.
The Swiss project PumpiPumpe presents a low-tech solution that is even easier to apply. They made a collection of small stickers depicting all kinds of consumer goods. Every occupant of a building can paste the stickers on his or her mailbox, showing the neighbours which things can be borrowed from them. Apart from the ecological advantages, the project also stimulates social contact between neighbours.
More at PumpiPumpe. Their website is in French, German and Italian only. The stickers can be obtained for free if you live in Switzerland. If you live in another country, you only pay for the shipping (4 euro). Thanks to Christopher Santerre.
