Making, adapting, sharing: fabricating open-source agricultural tools

This is a story about people who build their own machines. It’s a story about people who, due to necessity and/or conscious choice, do not buy commercial equipment to work their lands or animals, but who invent, create and adapt machines to their specific needs: for harvesting legumes, for hammering poles, for hitching tools onto tractors.

The machines are just one part of our story, and this article will talk about encounters between people, tools and knowledge and it will take us to various places: Paris and Renage in France, Pyrgos and Kalentzi in Greece, and Tallinn in Estonia.

Let us begin our journey in Greece. In Pyrgos (southern Crete), there is a small group of people called Melitakes (the Cretan word for ants) interested in seed sovereignty and agroecology. It is a group that cares about organic farming and that tries to form a small cooperative. One of the things the group does is to plant legumes in between olive-trees or grapes. While olive trees are abundant in Greece, the land in between individual trees is usually not cultivated due to the distance necessary to avoid shading and foster the growth of the trees. So the idea was quite simple: use the unused land. However, the members of the group soon faced a specific problem: it’s hard to harvest legumes by hand and there are no available tools to do this arduous job in a narrow line between olive trees. On the market, there are only big tractor accessories, suitable for such a job, and only for large crops. That is why the group sought the help of a friend in a nearby village, a machinist, to help them out. He liked the idea. He saw it as a challenge and started to develop a tool (see picture 1).

Our Economy is a Degenerative System

Impacts of resource hungry exploitative economies

“What is 120 times the size of London? The answer: the land or ecological footprint required to supply London’s needs.” — Herbert Giradet

Our ecological footprint exceeds the Earth’s capacity to regenerate. A number of useful indicators and frameworks have been developed to measure the ecological impact that humanity and its dominant economic system with its patterns of production, consumption and waste-disposal are having on the planet and its ecosystems. The measure and methodology for ecological footprinting translates the resource use and the generation of waste of a given population (eg: community, city, or nation) into the common denominator of bio-productive land per person, measured in Global Hectares (Gha), that are needed to provide these resources and absorb those wastes.

Much of the educational power of this tool is its capacity to compare between how much bio-productive land exists on the planet with how much bio-productive land would be needed to sustain current levels of consumption. In addition it also helps us to highlight the stark inequalities in ecological impact that exists between different countries.

Ecological Footprinting is basically an accounting tool that compares how much nature we have and how much nature we use. He are currently using about 50% more ecological resources than nature is regenerating naturally every year.

This point of spending more than is coming in every year — or living of the capital rather than the interest — was reached by humanity in the late-1960s. It is called Ecological Overshoot and every year since Earth Overshoot Day — the day when humanity as a whole has already used up the bio-productivity of Earth in that year — is a little earlier. Here is a little video (3:30 min.) to explain the concepts of ecological overshoot and footprint.
