About our Work

Contour Lines’ founder, Sean Dixon-Sullivan, named the nonprofit after one soil conservation method, one he has been using in the steep, high-rainfall tropics of Guatemala with much success.  Contour Lines are rows of trees planted level along a hill’s contour. They intersect rainwater runoff, trap eroding soil, and build terraces of fertility over time. <<See Supporting Research>>

Work, not words.

Our greater goal is a symbiotic mindset, one that unites human with nature, farms with forests, the economic with the ecological, one that understands and practices reforestation and regenerative agriculture. 

Contour lines are one of many techniques, but by choosing a base method and implementing it, we adpot a hands-on, project-oriented approach. Locals are incentivized to adopt these regenerative methods by offering these fruit tree grants. Results are measurable, literally, in feet. Upon the first visit to a new village, we meet the community and introduce the agreement. On the second, we build an A-level and start marking contour lines. Then after a quick supervision of the required Contour Lines methods, we deliver the fruit trees and we plant.

No meetings about meetings, no preaching and wasting time. No pointlessly gathering lists of people who say they want trees, only half of whom will even show up to the first work day. Our Community Engagement Model is designed through 6 years of experience, through feedback from our team of local field techs (and from the principles of “Two Ears of Corn” by Roland Bunch) to weed out the less-than-dedicated, and quickly train and expand the sites of those more-dedicated, those who will achieve results.

And this strategy has achieved results….

In the eastern region of Izabal, Guatemala Contour Lines has:

  • funded and planted 15,708 projects across 429 villages,
  • planted 2.8 million trees, trees, including 55 different species of fruit trees, where only corn monocultures grew before,
  • trained over 40k locals in Contour Lines methods, including 65 who are now experienced trainers themselves,
  • begun developing business models to value-add the harvests, to bring income and nutrition to these communities,
  • reduced the costs of our food forest projects by 70%, from $671 per acre to $184 per acre,
  • expanded our support based to include over 235 individual donors, and partners such as One Tree Planted, Ecosystem Restoration Camps, Abundant Earth Foundation, and iGiveTrees.

Now, heading into our 12th and largest planting season (2025) we focus on the sustainability of these projects. Our Value-adding and marketing pilots have proven successful and ready to replicate in these communities, while our team of locals—formerly project benefactors, now trained as teachers and organizers—expands these projects into more communities while forming their own legal association to continue this work beyond Contour Lines.

Furthermore, we’ve expanded our models into nine new regions of Guatemala—Barrios, Peten, El Estor, the Verapazes, Lake Atitlan, Huehuetenango, the Dry corridor and Antigua—while accepting applications from farmers interested in applying our models throughout Central America and beyond…
