You have read the syntropic agriculture theory. Four consortia, four strata, aggressive pruning. Sounds good on paper. The honest question is: has anyone actually done this at scale and what did it produce? The answer is yes, on several continents, for over forty years now. This guide walks through the real farms with the real numbers, from Ernst Götsch's flagship 1,186 acre operation in Bahia to Mark Shepard's Wisconsin perennial farm to a Vermont rice paddy that should not exist by conventional standards.
If you have come from our pillar on what syntropic agriculture is, this is the evidence file. If you are weighing whether to try it on your own land, the case studies below tell you what is documented, where it has worked, and where the limits are.
Ernst Götsch arrived in southern Bahia in 1982 and bought 480 hectares (1,186 acres) of degraded cattle pasture that the locals had called Fugidos da Terra Seca, "Escaped from the Dry Land." The springs had stopped running, the soil had washed into the rivers, and conventional agronomy would have prescribed lime, synthetic fertiliser, and mechanical cultivation. The Organic Consumers Association documents that Götsch chose a different path: dense, stratified, multi-species plantings designed to mimic the local Atlantic Forest succession.
Forty years on, the result is the most documented working syntropic farm on earth. The Fondation Prince Albert II de Monaco records that the property recovered 17 permanent water springs and rebuilt its own microclimate. ReNature.co profiles the "planting water" effect: trees pulling moisture down from regional weather and storing it in the soil profile. Mongabay documents the cacao production, with Götsch's farm exporting organic chocolate at premium prices to European buyers.
Key Takeaway
Olhos d'Agua is the syntropic case study everyone else is benchmarked against. 1,186 acres of degraded pasture turned into a productive forest in roughly 40 years, with measurable recovery of water tables, microclimate, soil organic matter, and biodiversity, all while producing premium cacao for export. The model is not theoretical. It is on the map.
The peer-reviewed yield numbers come from a long-running comparison trial in Alto Beni, Bolivia. Researchers tracked monoculture, organic monoculture, conventional agroforestry, and organic syntropic-inspired agroforestry plots for 25 years. Tropenbos / Rüegg 2024, Dynamic Cocoa Agroforestry: 25 Years of Experience documents the findings.
The headline number for sceptics: mature-phase cacao yields in the agroforestry plots came in at roughly 75% of the monoculture plots. Looked at narrowly, that is a yield loss. But the trial also tracked 22 additional crops harvested from the same agroforestry plots: bananas, plantains, timber species, pigeon pea, vegetables. When all of those were included, total system yield ran up to 6.9 times the monoculture. The conclusion is consistent with what large-scale comparative reviews keep finding: syntropic farming trades a small fraction of single-crop yield for a multiple of total food and ecosystem output from the same land.
The Lancet Planetary Health published a 2025 multi-country review of syntropic farming systems. PubMed 40252678 concludes that syntropic farming systems "enhance agrobiodiversity, carbon storage, soil fertility, and water cycling" across the climates surveyed. That is the peer-reviewed top line on the whole approach.
The strongest evidence that syntropic principles transfer beyond the Brazilian tropics is that working farms now exist on four continents and three climate zones. The species change, the framework holds.

Mark Shepard bought 106 acres of degraded corn ground in the Driftless region of southwestern Wisconsin and converted it into one of the most ambitious temperate-zone perennial agriculture experiments in the United States. New Forest Farm: Redesigning Agriculture in Nature's Image is the farm's working website.
The species list is what makes the case for temperate adaptation. The farm runs on hazelnut, chestnut, walnut, apple, asparagus, currant, and grape, planted in alleys and contoured strips that hold soil and water on rolling terrain. Shepard's Forest Agriculture Nursery propagates the cold-hardy genetics that make the system possible. He calls the selection process STUN, "Sheer Total Utter Neglect": plant ten varieties, kill the weak ones with no protection, and propagate the survivors. The result is a farm that gets stronger, not weaker, with age. Shepard's published yields per acre, when totaled across the multiple producing species, hold up against conventional corn-soy monoculture in the same region.
Ben Falk's Whole Systems Design farm in northern Vermont takes the syntropic logic to USDA Zone 4. The site sits at altitude in a climate where conventional wisdom says rice cannot grow. Falk grows rice. Whole Systems Design, Growing Rice in Northern Vermont documents the paddies, the variety selection, and the integrated duck system that controls weeds without herbicide.
The farm also runs apple, pear, and stone fruit orchards on cold-hardy rootstocks, perennial vegetable beds, and a 20+ year track record of consulting work. Whole Systems Design Projects shows the design work the farm has done elsewhere in cold-climate North America. The Vermont site is the proof that the syntropic stacking principle adapts to short seasons and serious winters as long as the species selection respects the climate.
Why This Works: The Framework Travels Better Than the Species
Olhos d'Agua, New Forest Farm, Whole Systems, and La Loma Viva look nothing alike. The cacao at Götsch's site would die in a Wisconsin winter. The hazelnut at Shepard's farm would never set on a Brazilian afternoon. What transfers is not the species list but the framework: plant all four time horizons at once (placenta, secondary I, secondary II, climax), stack four strata of light (emergent, high, medium, low), and prune aggressively to drive the biomass cycle. Beneath the surface, every working syntropic farm runs the same engine.
The water story is the one that lands hardest for sceptics. The Fondation Prince Albert II documentation credits Götsch's reforestation with the return of 17 permanent springs on the 480 hectare property. The mechanism is straightforward but slow: dense layered canopy reduces wind speed at ground level, increases nighttime condensation on leaves, and slows runoff long enough for water to percolate to the aquifer instead of flooding downhill. ReNature.co's "planting water" piece explains the soil-biology side: deeper roots, more soil organic matter, more aggregate stability, more water-holding capacity per cubic foot.
The soil microbiome data is starting to catch up to the practitioner claims. A 2025 peer-reviewed study on PubMed compared soil microbiome composition in temperate agrosilvopastoral and syntropic agroforestry systems versus adjacent monoculture, and found measurable shifts toward forest-system microbial communities under syntropic management. The 2020 MDPI Agriculture study on adapting syntropic permaculture to a former quarry area documents soil restoration on a previously-mined site in temperate Germany.

Send Me the GuidePractitioner economics differ from peer-reviewed yield trials, and both differ from coffee-table dreams of forest farming. Mountain Time Farm's working paper on the economics of syntropic agroforestry gives the cleanest accounting of what a Colorado-based small acreage syntropic farm actually earns, when, and how. The honest version: year 1 to 3 the cash flow is annual crops and pioneer harvests, year 4 to 10 the bush and small tree crops start producing, year 10 onward the mature timber and nut layer adds to total revenue. Total payback on the establishment investment typically lands between years 7 and 12 in temperate climates.
Götsch's own scale-up paper, Large-scale Syntropic Farming results and challenges, documents how the system performs at multi-hundred-hectare scale. The successor practitioners who carry the work forward, profiled in FiBL's profile of Felipe Pasini and Dayana Andrade, are running farms across Brazil, Portugal, and France. Cold-climate adaptation work in North America is documented by Propagate Ag's cold-climate syntropic agroforestry guide.
Ernst Götsch's Fazenda Olhos d'Agua in southern Bahia, Brazil, at roughly 480 hectares (1,186 acres). Götsch began the work in 1982 on degraded cattle pasture and reforested the entire property into a productive Atlantic Forest agroforestry system. The farm produces premium cacao for export, recovered 17 permanent water springs, and has been documented by the FAO Family Farming Knowledge Platform, Mongabay, and the Fondation Prince Albert II de Monaco.
Yes. A 2025 multi-country review published in The Lancet Planetary Health concluded that syntropic farming systems enhance agrobiodiversity, carbon storage, soil fertility, and water cycling. A 25-year cacao trial in Alto Beni, Bolivia compared syntropic agroforestry to monoculture and found total system yields up to 6.9 times higher in the agroforestry plots when all secondary crops were counted. A 2025 PubMed study documented measurable soil microbiome shifts in temperate syntropic systems.
Mountain Time Farm's published economic accounting suggests typical payback periods of 7 to 12 years for temperate-climate small-acreage syntropic farms. Year 1 to 3 the cash flow is annual crops and pioneer harvests, year 4 to 10 the bush and small tree layer starts producing, year 10+ adds mature timber and nut revenue. Tropical syntropic farms tend to pay back faster because the canopy establishes in 3 to 5 years.
Yes. Mark Shepard's 106 acre New Forest Farm in southwestern Wisconsin uses cold-hardy hazelnut, chestnut, walnut, and apple. Ben Falk's Whole Systems Design farm in northern Vermont grows rice in paddies at USDA Zone 4. Propagate Ag and Mountain Time Farm have built practitioner networks across cold-climate North America. The framework transfers; the species list changes.
In the Alto Beni Bolivia 25-year trial, mature-phase cacao yields ran at roughly 75 percent of monoculture, but total system yield (cacao plus 22 secondary crops harvested from the same plots) reached 6.9 times the monoculture. Götsch's Bahia farm produces premium-priced organic cacao alongside fruit, nuts, timber, and ecosystem services. The pattern is consistent: small reduction in the single primary crop, large multiple in total system output per acre.
Yes. La Loma Viva in Andalusia, Spain runs Mediterranean-climate syntropic systems. A peer-reviewed 2020 MDPI Agriculture paper documented syntropic permaculture renaturation of a former quarry in temperate Germany. Felipe Pasini and Dayana Andrade, profiled by FiBL, train practitioners across Portugal, France, and Brazil. The European Agroecology Research Alliance has published farmer-led research on full-system productivity.
The most active successor practitioners include Felipe Pasini and Dayana Andrade (Sintropia Brasil, profiled by FiBL), who run training programmes and farms across Brazil and Europe. Mark Shepard developed his temperate-syntropic methodology independently with reference to Götsch's principles. Ben Falk's Whole Systems Design integrates syntropic logic with broader permaculture design. Mountain Time Farm and Propagate Ag publish practitioner-network materials for cold-climate North America.
