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…

EU: No Net land Take ?

A new regulation is in the making in Europe: No net land take. PBL ( NL environmental assessment agency) recently organized a meeting on the topic.[1] It’s an interesting approach and wording, but what’s really the point? First, there is the assumption that no more land should be sacrificed to…

Where to build, and where not to build (in NL)

I was asked that question last year by Thomas van Belzen of Cobouw,[1] and it got me thinking. It was an interview in Dutch, but let me return to it in English and in more detail at the beginning of 2023. The first reaction is of course: why build, we…

The ‘Solar Space’, per m2 of living area 2/2

Since we are in an energy transition , in which we completely switch to renewable energy, the energy at building level will mainly have to come from solar energy. We assume that, the more local energy the better, and a ‘0 energy house’, including compensation for material energy, to be…

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…
