From the field #South_Africa

Funded by the Royal Society, I was travelling to Southern Africa to do measure & map quality of crop and non-crop habitats. Yes, that’s right. I have started to venture beyond the forest/woodland/shrub/savannah edge and into that thing called matrix to try and figure out how the distribution of natural habitats (let’s call it wilderness) AND its quality variation within the landscape builds meaningful (translate to ‘ecosystem service’) relationships with cropland productivity (translate to yield and crop health).

This is a pilot study. And the aim is not to prove these relationships. We know they exist. What we don’t know is how exactly quality of natural habitats co-varies with quality of crop habitats and to what extent this co-variation is driven by natural pest control and pollination links or microclimate.


With support from local collaborator Dr Pieter Olivier (see pictures above), formerly postdoc of the University the Pretoria and now co-director of environmental consultancy M.A.P Scientific Services (, I tested some new sensors (NDVI, thermal) beside taking some old sensors (hemis). The primary idea of this pilot was to develop sampling protocols and ‘automatize’ fieldwork and processing steps for follow-up large scale research projects. But I also tried to identify key patterns and metrics I want to use to characterise co-dependencies between forest and crop ‘health’.








What are the next steps: (1) Process and analyse the data. There are lots of them and the thermal data in particular need some more attention than the others. (2) Generate sampling sheets and protocols and design / adapt sensors used to make them more efficient to use in the field. (3) Upload report and key findings to our websites. (4) Wait for the big grant allowing us to test our big ideas to come through. 🙂

PS: We did see some cool wildlife, too. And some deforestation involving swamp forests presumably for growing crops on the rich black soil underneath. I also now feature a brand new exciting scar,unfortunately not because of wild animals but because of a very silly approach to handling a drone 🙂
