What’s best for nature?
- Concentrate human impacts in fewer places (land sparing)?
- Or spread them more lightly across wider landscapes (land sharing)?
A debate with deep roots in agriculture, geography, planning & conservation. New article in Landscape Research: doi.org/10.1080/0142...
Land sparing and land sharing in spatial planning: bridging historical ideals and contemporary applications
The ‘land sparing and land sharing’ framework clarifies how land use can either concentrate intensive activities in specific areas (‘sparing’) or integrate multiple uses across a wider landscape (‘...

Samlet utbyggingsareal i Kommune-Norge: Historisk utvikling og framtidige scenarioer, 2000–2050
Flere kommuner har mål om arealnøytralitet, men dette kan komme i konflikt med behov for arealer til samfunnsnyttig utbygging. Her undersøker vi arealeffektivitet og utviklingsbaner for arealbruk i Ko...

Land has the honour of appearing in the Global Carbon Budget twice!

Once as an anthropogenic source: deforestation, afforestation, forestry

Once as a natural sink: CO2 fertilisation, climate change, etc

On balance, land is a sink, primarily due to CO2 fertilisation from fossil CO2 emissions!

Chapter 1: Introduction to Geocomputation 🌍📊

What is geocomputation? Why use R for spatial analysis? 📌 This chapter traces its history, connects it to FOSS4G, and explores R’s power for geospatial work. Learn about R-spatial’s evolution! 🚀

Open letter from nearly 2000 NAS member scientists: "We see real danger in this moment. We hold diverse political beliefs, but we are united (...) in wanting to protect independent scientific inquiry. We are sending this SOS to sound a warning: the nation’s scientific enterprise is being decimated."

By attacking science:

We are less safe because science informs national security and medical care.

We are less prosperous because science drives innovation and economic benefit.

We are less free because science and democracy depend on the liberty to ask questions, and seek and share knowledge.

Conservation isn’t just about protecting land—it’s about where and how we do it. If protecting one area pushes deforestation, farming, mining elsewhere (biodiversity leakage), we risk a net loss. Smart site selection, demand reduction & sustainable offsets are key!

Time to fix the biodiversity leak
The risk that locally successful nature conservation may be shifting problems elsewhere can no longer be ignored

Crop improvements from 1961–2015 reduced cropland expansion, lowered greenhouse gas emissions from land use change, and prevented thousands of species extinctions, compared with a counterfactual scenario without crop improvements. In PNAS: www.pnas.org/doi/10.1073/...

Ecosystem accounting, a framework developed by the United Nations, standardises data on the state and condition of ecosystems. The method has been used on a coarse scale, but it can also be applied to areas of smaller extent and at a finer scale. www.idunn.no/doi/10.18261...
