A EU Referendum: wine, or soybeans, or solar panels?

I’m sitting on a terrace on the borders of the Moselle, tasting some local wine. And looking out over the slopes along the Mosel, I come to a rather confrontational observation: we have deforested an enormous area, in order to be able to grow our wine… All the southern slopes…

Where to buy 1 ha of sea …

The other day I was thinking, I’m going to invest some money in land, since it has a stable value, or at least, has lasting ‘value’. But then I realized that this has mainly (for the time being) financial value, because the land itself is completely exhausted, exhausted by farmers…

From EROI to EROLI: energy return on Land investment ? 2/2

In the agricultural project that I described in my previous contribution [1], which was initially about the EROI, the energy return on energy investment, I subsequently calculated the effects back to land’input’. But then the thought soon arised: would is also be possible to develop a LROLI, a Land return…

EROI and land use of potato crop – a pilot 1/2

In a recent project , ‘Verrijkende Landbouw’ ( Enriching Agriculture) [1], I was able to refine the theory and methodology of MAXergy, using Embodied Land as an indicator [2], thanks to a practical pilot. As follows. Agriculture needs to change. That should be obvious by now. And not only regarding…

The Bionological House

With vegetables, we’ve been doing it for years: most current vegetables never existed, in an autonomous evolutionary process. We as humans have slowly transformed them so that they grow the way we appreciate them, and want them on our plates. (Or the industry has adapted them the way we want…

Carbon storage: the land-time relation 2/2

There are many ways you can start “accounting” for CO2 (as comments on the previous article also showed), but at the end of the day what matters are absolute CO2 emissions, from whatever activity. And cutting down a tree and using it as a column (or a table, or a…

DELY : Disabled Earth Life Years

We can develop beautiful so-called scientific methods to calculate all the effects of our impact, but in the end only two data are relevant: energy and material use, and the rest is derived from that: all emissions, to air or water, pollution, disappearance of forests, , and climate warming and…

Land, between heaven and earth

It is intriguing how the world fundamentally works, with its cycles, driven mainly by solar energy. Which can be traced back mainly to the yields of land, as I found out earlier. [1,2] (Land that has virtually disappeared from economic theory as a production factor). But yields from land is…

land (-potential) as the new money standard

Someone suggested recently to think about a new money standard. Well, thats a challenge, so I did. Since money is a virtual unit of trade, not based on any actual value. Not anymore, at least, since we left the barter economy and entered the money exchange economy, somewhere around 1600,…

Living from 2 hectares, and not even that…

During the holidays I was philosophizing about the previous article, the biomass growth reference. And look, it is actually very simple: per person there is about 2 ha on earth for each of us. That is everyone’s personal “resource bubble”. You actually have to provide food, collect energy, building materials,…
