New paper out in Ambio mixing art and remote sensing

A paper I have been working on for a while with Hakim Abdi was recently published in Ambio under open access license. It compares what we can learn from linking participatory art and local experiences of land use change with remote sensing and land change detection. The paper is linked to fieldwork I did in Tanzania in 2015 and 2016 and is called “Mapping and quantifying perceptions of environmental change in Kilombero Valley, Tanzania”.

Comparing paintings of the past and the present with land change detection through remote sensing. Narratives and corresponding observations of environmental change are marked and highlighted in different colours. Green circles show the mountain forest as visualised in the paintings, and the corresponding area of the satellite image, mainly showing no change (white) and rainfed agriculture to forest (brown). Blue circles show forest loss in the valley as described in the paintings, and corresponding areas in the land cover classification (forest to rainfed, and forest to wetland). Pink circles show changes from wetland and rainfed farmland to irrigated farmland. Yellow circles show agricultural and pastoral activities expanding over the wetland area, which are seen as wetland to rainfed in the land change detection.

Virtual talk about land grabbing at Almedalsveckan

I will be having a virtual presentation at Almedalsveckan tomorrow, 4th of July. If you are there, I think it will be a very interesting session!

Sustainable Land Use? Synergies, Conflicts, and Solutions for Sweden and Beyond

Tid: 11:15 – 12:15
Plats: Hästgatan 13

Medverkande:

  • Genevieve Metson, Assistant Professor, Theoretical Biology IFM and Center for Climate Science and Policy Research, Linköping University
  • Emma Li Johansson, Researcher, Department of Physical Geography and Ecosystem Science, Lund University
  • Kimberly Nicholas, Associate Professor, Lund University Centre for Sustainability Studies

How does Swedish farming and food consumption affect ecosystem services here and around the world? What role does agriculture in the EU, particularly the CAP, play in driving Agenda 2030? How can we sustain food, energy, biofuels, climate regulation, and thriving nature with limited land resources?

Chapter in telecoupling book

Me and Jonathan Seaquist just published a chapter in the book “Telecoupling: Exploring Land-Use Change in a Globalised World“. The chapter is entitled “Toolbox: Operationalising Telecoupling with Network Analysis” and demonstrates how network analysis can be used to clarify understandings about the effects of globalisation on land system change.

A simple network representation consisting of nodes (labelled A to E) and links (lines connecting the nodes). Nodes can represent people, institutions, states, or governance structures, whilst links depict connections between the nodes in terms of material, people, energy, or information.

Large-scale land acquisition affects farmers’ ability to produce their own food in Africa

“In order to avoid water conflicts and to stimulate food production in sub-Saharan Africa, large-scale land acquisition must be regulated and focus on food production. These are the conclusions of a new doctoral thesis from PhD Emma Johansson.”

Lund University Center for Sustainability Studies (LUCSUS) writes a nice piece about my thesis, and also made a nice video illustration about some key points.

 

 

Freelancing as science illustrator

Do you need a compelling and clear figure for your grant proposal? Or do you need a better-looking figure for your publication?

I have a particular interest of visualizing science as graphs, maps, paintings, and even stop-motion movies (see some examples here). If I could choose, I would only make figures all day. A nice illustration is such a good and efficient way to catch someone’s attention and communicate your scientific results. 

I am currently part time freelancing as a science illustrator,  so if you need help with tables, charts, figures, maps, or other visualizations, don’t hesitate to contact me (emmalijohansson@gmail.com).

Conceptual model of networks and network analysis

 

PhD thesis in print

My four years of research as a PhD candidate has come to an end, and the results have been compiled in a thesis. Here is an online version of my “Kappa“, which is a summarizing and conceptualizing chapter to complement and add a bit of context for the four papers of the thesis (three published, one in review).

Welcome to join the defense, which will be held the 14th of September at 10:00 in Världen, Geocentrum I, Lund University. Associate Professor Line Gordon from Stockholm Resilience Centre will be my opponent.
