Last weekend I visited the farm. Little time as I have to go back to Makati same day, we only worked on this area. The 4th layer or row was repaired after the soil it was standing on has sunk.
How tall is this mini-dam, well compare its height with Danny, Nong Endring's son and helps his father in the farm, and Danny is about 5"10'.

I visited the farm last Saturday. Previous weeks, we added the 4th layer as the stones continue to shrink, though at low rates now.
Side view, and left side of the structure, below.
And here is the adjusted structure, moving to 5 layers from the previous 2-3 layers. Nong Endring is standing at the top putting new grasses and leaves. See his height compared with the height of the structure. It's simply getting higher, sturdier.
The mini-pool at the back of the structure, the impounded water. Above photo, taken 3 weeks earlier.

The 3-layer terraces, March 2015 (top photo) and July 2015 (below). We started building the 4th layer last month.
Two weekends ago, I visited the farm. The big "wall" that we built several years ago, the stones are shrinking, as the soil below them becomes compacted. Time to adjust them. We removed one layer of stones each on the first and second rows, and put them on the third row.
Below, before we worked on it. Notice the 3rd row, the sinking is visible...
After. The 3rd row became higher and more prominent.
Top view, before and after. Behind the big stones in each row are many smaller stones to stabilize them. Plus soil and organic matter as additional but weaker back up materials. Where did we get the soil and additional smaller stones...
From here. The trapped organic matter that has decomposed and became very soft soil. We removed about six inches deep on average here. This area becomes a temporary pool of trapped water and organic matter during heavy rains. Meaning, it can reduce a huge volume of water and hence, reduce flash flood, and reduce or prevent erosion of precious top soil in this part of the farm.
