The most important work is now. Ponds and swails must be dug to retain water at the top of the property. Coffee, Palms, and Jatropha were recently installed thanks to a developer contract, but the early dry season of mid December, with no mulch (piles of browned tall grass curiously piled at bottom of the hill) and no water supply. Even when you do everything right, "Modern" agricultural techniques are incredibly wasteful and cause topsoil runoff. Permaculture designs hold water on the top of the property and feed a diverse system of micro-habitats. Following the natural contours with a shovel is job #1.

This week, an ambitious mycostaricafarm has a Tico crew converging upon the site this Friday, to build a very simple 6-post structure.
A "huminor" style bathroom is also a high priority, as the landscape needs lots of soil fixers.
The Tico Way may prevail on this building, as tribal engineers have yet to find the farm, Costa Rica One Love.
