The Madness of Vertical Agriculture (2)

Vertical farming, and thus “indoors,” is a form of enormous technocratic hubris, which costs more than it yields. I wrote about it before, that trying to beat nature, millions of years of evolution, is complete madness.[1] Growing crops via natural selection/cropcrossings and maybe indoors ( unheated greenhouses),with yields accelerated thus…

We need yearly a land-budgetting

The Netherlands is grappling with its land. With its land management and spatial planning. From all sides, there’s a demand for scarce land: by livestock farmers for pasture and spreading manure, they want to expand more and more. But also for construction, roads, and solar parks. And data and distribution…

Sheep (and wool and land and etc.)

Regularly questions and discussions arise about wool and sheep [1]. Is it effective and/or useful, is it better/worse than alternatives, and so forth. Time to delve into that and try to put it into perspective. First, let’s look at some numbers: There are approximately 800.000 sheep in the Netherlands, producing…

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…
