Pre-inventory Meeting

Flickr Slideshow of the Thon 4 Meeting

Yesterday we travelled to Thon 4 (village 4) to meet with the villagers and start the forest inventory process. I took a lot of pictures and you can follow the meeting with the slideshow above.

Unfortunately, the farmers were not available for the dates we hoped to do the inventory since they are busy harvesting their crops from the fields.  There seemed to be some political element to this since the local government representative was particularly adamant that if there was any future hardship related to this crop cycle then the political party might take the blame.  When the ethnic minorities are concerned politics becomes an even greater influence over action.

Moving forward

This week’s been fraught with problems for the forestry component of the project so it has been difficult to put together a comprehensive plan about where we are going with REDD until today.

We’ll be doing another forest inventory of a region very near to the last one.  So, first of all, I will try to update the forest map as best I can with satellite images and field visits so that when we place the measurement points we don’t end up in the middle of coffee plantations.  Like last time.  I’m then going to put together a short questionnaire for the M’Nong villagers who help with the inventory, with questions about them and their lives.  Those data, along with some nice profile shots, will be a great addition to the map data once it is online; it will show that we really got to know the local people and put faces to the issues in the area.  These will, of course, be incorporated into Google Earth as balloons so they’ll pop up in context as people are using the site.

Getting a hold of good satellite imagery is turning out to be a bit of a problem but at this planning stage it might be enough to use LANDSAT images although a) the resolution is a bit weak and b) the recent images have these annoying blank lines through them because of a fault on the satellite itself in 2003.  We’ll make do, of course, but will be begging the people from the Japanese International Cooperation Agency who are here next week to lend us theirs…

Why is it that the world’s leading GIS software company make it so much less than simple to import rich GPS data?  Having spent much of the morning tracking down a nice program that works we can now see some of the additional points we made splayed out on the map.  The rest is joining the dots.

These extra points are largely Christian’s attempt to find the boundary of the region of forest, normally a prerequisite for forestry itinerary planning, but in our case the forest is so scattered and the undergrowth so thick that hacking through that enormous perimeter would take weeks and weeks of expensive time.

Having those GPS data in place I spent the afternoon testing classes in MultiSpecCarb so that when we have good satellite images, the processing will be a breeze…

Out in the woods

leave a comment »

Out in the woods there’s only the rustle of the trees, the crunching of sticks and the screeching of the cicadas to break the silence of our single-file team of 5 farmers and a technician as we wind between the trees quarrying the coordinates in our GPS.CBD_0006

At least most of the time.  Occasionally we were knee deep in swamp and very often stopped by the undergrowth, forced to hack our way through while a surprisingly large number of spiky things dragged at our clothes and skin. But those things make it sound like it was not fun, and it was a lot of fun indeed.

The measuring went very well, it is simple once everyone knows their place in the drill.  Christian noted that the M’Nong farmers were much more sensitive to the different tree species than the outsiders and so by the second day we were all supposed  to be recording the infinity of M’Nong tree names.  This did not slow us down at all as the farmers seemed to know the plants inside out: only once did they stop to sniff and chew every part of one plant that they did not to recognize and even differentiating between the flavor of the skin of the stalk and its leaves.


Occasionally, the friction as we passed through became too much and we were forced to skirt the edges of what was normally an area where uncontrolled deforestation had left a thick undergrowth.  It was also depressingly common to find that places marked as forest on the map are now coffee, sweet potato or cassava plantations.  We will have to wait and see what the new map looks like and the picture of deforestation that we’re looking at.

Getting out into the sunshine…

leave a comment »

Like my little Honda, things can be slow when you’re battling up-hill.  But we’re getting somewhere at least and the only frustration is that I have not been available as an active player yet.

The forest inventories are coming going and Christian spent much of his weekend training and re-training so that we are ready to get out and measure the trees this week.  The plan is to directly measure


1% of the forest and I have drawn up a set of random points within the area that we can quickly locate, demarcate and measure up.  Some doubted that the villagers could read numbers well enough to record the diameters of the trees accurately, so Christian drew a note out of his pocket and asked, “how much is this?” “50,000 Dong” rang out the chorus: case proven.  The villagers are more capable than some people hasten to think.

With steep slopes and the ravages of deforestation leaving a thick undergrowth, measuring the forest is not entirely straight forward.  With 1% measured we have 126 locations and 4 teams which means, for all practical purposes, we need to get measurements down to 4-5 per day.  That’s some fast work.

Start-up with the project

with 2 comments

Dak Nong, Vietnam is an extremely comfortable five hours journey north of Ho Chi Minh City.  The proximity to Cambodia and the diversity of this five year old central highlands province has left it rather sensitive about international personnel who make requests to work.  This might make one wonder why anyone would work in this region at all.   Well, a recent study showed that Dak Nong has some of the highest forest coverage of any province and that over a 7 year period the forest has been diminished or degraded fastest: a good reason for forestry projects to locate here.  It is important to note that some the sensitivity of the region is related to the ethnic minorities that live here and that they’re arguably more in need of outside assistance than any other group.


Although I am here with CartONG I am working under the auspices of GTZ.  GTZ is a German technical assistance group that has a number of projects scattered throughout the country.  They’re working on all manner of economic and ecological development projects but from my perspective, the most relevant project is a Community Forest Management project which aims to maximize the opportunity for wealth creation from timber while maintaining the overall structure of the forest for ecological purposes.  CFM works by allowing timber cutting to take place but in according to a sustainable plan.  This requires a lot of collaboration with villagers on the ground and relies rather heavily on the participation of local government.  Additionally, CFP gets people in and around the forest which fosters good conditions for ecological protection.  We hope that we can build a CFM plan into the carbon content model that will estimate stable and dynamic changes in the forest’s carbon capture capabilities.

We have just confirmed that next week we’ll head out into one of the study sites and, with the help of local people and hordes of forestry students, make a forest inventory that can be used in the carbon capture models.  This will be an exciting opportunity to get into the field, get out the GPS and make some maps.
