The canals you made look fine. I'll go through each land management area included in the shp file I sent you.
The fruit tree alley cropping system will be a combined fruit-forage system. We will experiment with different forage crops, and use some terracing, especially live barriers like Paraguay grass, vetivier, and Phalaris within the tree rows to reduce erosion and get some slow forming terraces going along the contour. Moises has a brilliant low tech idea to use 10 liter plastic vegetable oil containers, make little holes in them, bury each one in the ground beneath the tree so only the opening is sticking out, and attach them to a polytube system from the atajado as a "drip irrigation" system.
Grains-grasses-legumes will be a mixed, rain-fed system using primarily local species, like amaranth, quinoa, and maize, but perhaps also some perrenial forage crops mixed with legumes like lablab bean, soy, and other nitrogen fixing legumes. Ideally we'll install some kind of terracing system there as well. The system will rely heavily on green manures to recover soil fertility.
Above that on the slope is a reforestation scheme, which will primarily use native species for erosion control, forage production, and other useful forest products like resins and natural pesticides. Take a close look at the V shaped water catchment and reforestation system in the slide show I sent you, as they will fill up the reforestation area.
The silvo-pastoral system will not require any atajados or canals, per se, as the soil type isn't appropriate, the slopes are steep, and there isn't much water to capture. We'll be looking more to build infilitration ditches along the contours combined with a rock-live terrace system, and then plant drought tolerant grasses, legumes, and bushes/trees for seasonal forage production with low labor inputs (once the system is established).
Productive infrastruture will include things like CEA, but also a place to produce pigs, a cattle corral, and a check-dam/gulley control system like you see in the slide show, maybe with some eucalytpus trees at the fanning mouth of the gulley.
The ram pumps will be used in combination with the irrigation canal during the wet months of jan-feb, as people don't even take their watering turn in those months. We can pump water up to the potential atajado in the productive infrastructure area and the ferrocement tank in the nursery. Also, you can build a canal to catch the water from the catchment area above the actual atajados to the potential atajado in the productive infrastructure area, as all the water filling the actual atajados will come from the ephemeral stream.
The ram pumps by the canal Moises built will be used to pump water from the ephemeral stream up to the potential atajados in the reforestation area.
The canal you have that comes around the gulley will work well, try to find some ways to capture some more water from the silvopastoral area and bring it around to the atajado(s) on the other side of the gulley.
Connecting the atajados won't be necessary, as we'll lose water as we move it from on atajado to the other.
Also, you might want to consider putting another atajado in the area where we have the "meliponas", if you think it could be useful or necessary.
We can start wrapping up now, I think we've done pretty well. If you have questions, ask them now, as I'll be going to Mizque for a much needed three day weekend this afternoon.
