thank you for sharing your questions! We are about to conduct the
stakeholder workshop in Cusco, Peru, so expect more results from South
America on this list shortly.

Thank you, Hinrich, for making this material more broadly
For the benefit of others on the list, I wanted to share questions I asked Hinrich
off-list regarding these results, and his answers.
• the most high value/feasible challenge to address is #43, which isn’t listed by name?
#43 is 'monitoring work progress' which was deemed the most important while
having a technical solution
• “High resolution data” might be second; does this refer to higher resolution satellite
imagery than ESA provides? (have you worked with Planet data?)
we differentiate in our work 'high resolution' (HR) (i. e. Sentinel --> 10m
pixels) and 'very high resolution' (VHR) data (i. e. Planet --> aprox. 3 m
pixels, World View --> aprox. 0,4 m pixels etc.). We have worked with Planet and World
View and yes, this is what a lot of organisations are interested in. I have my doubts
whether our differentiation of HR and VHR data was actually reflected in the answer, most
probably it should read 'VHR data'
• is “monitoring tree growth” dependent on “high resolution data”?
according to my definition above monitoring tree growth is dependant on HR data, while
you can also use VHR data but which is not necessary. Then again it depends on what you
want to do; if you are just interested in the vitality of trees then HR data is fine but
if you want to extract tree heights or other such things then VHR data, also of the
non-optical (i. e. RADAR, LiDaR) type would be necessary.
• #50: does “interest towards exotic species” refer to the economic attraction of
non-native cash crops?
yes, it refers to non-native cash crops including trees
• #73: do you think this is in common with “monitoring tree growth” in Indonesia? did
you get a sense of whether this need (in both landscapes) was from a reporting point of
view (what % of trees are healthy/successful), or to drive action (e.g. special care or
attention to keep a particular tree successful)?
yes both, reporting and action. It all has to do with monitoring tree growth. However
there are certain programs in place where individuals plant and take care of one tree and
the idea here would be that instead of visiting your tree and taking pictures you could to
this with VHR satellite imagery. To get a sense of what I am talking about visit
and enter TAU000186
• #82: “client fatigue” – what was your sense of the technological solution in this
Basically having a map where organisations can see where everyone else is operating and
then either going somewhere else or creating synergies would definitely help.
• can you describe the charcoal production problem as it was conveyed to you?
The production of charcoal produces emissions and the wood comes from forests which are
then significantly degraded. In East Africa charcoal is used extensively for cooking which
carries severe health (respiratory) problems. Changing the mindset of the people is one
challenge while offering affordable alternatives without the negative effects of the
current practice is another.
