Ditch detection
For hydrological GIS modeling, I have created a model that can identify ditches (or streams, channels) in elevation raster data. The purpose of the model is to make it easier to visually identify ditches at any scale or to classify ditches. This model was presented in several steps on QGIS open day sept 24th, 2021. […]
Röst till salu
I den rika världen tjänar vi pengar och köper saker eller tjänster som vi vill ha. Saker produceras i en stor och komplex kedja av aktörer och sällan inom landets gränser. Dina köp av saker stödjer verksamheter och kan räknas som röster, likt en röst i politiken. Du röstar därmed varje dag. Men du vet […]

Skånes järnvägshistoria på webkarta
Skåne hade en tid väldigt mycket järnväg. Stambanan började byggas runt 1860-talet och efter sekelskiftet 1900 nådde järnvägen sin största omfattning. Idag återstår bara en bråkdel men både den som finns kvar och den som inte syns i landskapet har båda gemensamt att de har haft stort inflytande på samhället och har styrt samhällens placering […]
Da Vinci 500
My first app is finally on the App Store. The 500 year anniversary of Leonardo da Vinci’s passing is in 2019 and to commemorate this I’ve made an app for learning all you need to know about him. Enjoy! / Jacob
Ecotrippen – Sverige på cykel
Detta äventyr har vuxit fram sakteligen i mer än 6 år, men i år är det dags. Mitt intresse för miljö började växa för runt 20 år sedan. Den första riktiga cykeln köpte jag för drygt 8 år sedan och har bland annat cyklat i Skåne. Att filma har alltid varit kul men har hittills […]
We have already passed a tipping point
Watch disaster unfold as the world passes the first clear tipping point. Ice sheets are collapsing. The world of tomorrow will be very different. Perhaps what is more alarming is that even scientists continue to be surprised at how fast change happens. But will the world even notice when media fails to do its responsibility […]

I come from debt
It’s the inevitable headline, seen on Swedish television January 3rd, 2014. Maybe a world’s first. The World: Extreme weather. 2014 is off to a worrying start. Major floods in France and Britain while record ones in Brazil. Intense heat in Australia. Unseasonably mild weather in Russia and Scandinavia, sending ripple effects through ecosystems depending on […]

Sommaren 2009 förde cykeln mig till nya och gamla platser i det skånska landskapet. Följ min resa under 6 dagar genom värdefulla natur- och kulturmiljöer på iPad med en iBook tillgänglig på iTunes.
Abstract nature prints
Here are some of my Abstract Nature photographs. They might sometimes look like paint but they are pure long exposure photography.
Seeing isn’t believing
Let’s say there was 100 percent sea ice in the Arctic when I was born, right at the end of a summer melting in the late 70s. How much sea ice was there on my birthday this year? Guess. Not even close. Guess again. You know how some things aren’t easily visually perceived because it […]
Earth Year
Since 1970 we have celebrated Earth Day. A few years ago, as the ecological crisis approached certainty, we added Earth Hour. But now we need more than hours or days; we need a whole year. In Earth Year we stop. No more obliteration of natural ecosystems, no more urban sprawl and no more superfluous consumption. […]
Steve
The genius of Steve is no longer with us. His passion and determination inspired. His goal was always to make the very best of something, whatever the cost. He built things of beauty and simplicity that last. Put another way, he made the rest of the industry appear insanely mediocre. He also lived a simple […]
The destruction of wealth
Before society there was nature; much more so than today. There was wealth, and in fact there was as much wealth as there will ever be in the age of man. Today the term wealth has become synonymous with turning natural resources into goods and consuming those goods. The more consumption; the more wealth. However, […]
