Permaculture has become one of the most overused words in the hospitality and sustainable tourism vocabulary. It appears on hotel websites alongside photographs of potted herbs outside the kitchen door. It features in resort brochures next to images of a composting bin positioned artfully near the swimming pool. It is invoked by properties that have made one or two changes to their procurement practices and want a word that communicates more commitment than eco-friendly without requiring the specificity that certified organic demands.
The result is that permaculture, as a term encountered by the travelling public, has largely lost its meaning. Which is a problem, because permaculture as a design philosophy and agricultural practice is genuinely interesting, genuinely demanding, and genuinely capable of producing something that conventional agriculture cannot: a farming system that improves the land it works rather than depleting it, that produces food and agricultural products of demonstrable quality from the biological richness of a healthy ecosystem.
Skugga Estate in Mae On uses the word permaculture to describe its farming approach. This article is an account of what that means in practice at the estate: the specific decisions, the specific systems, the specific results. Because the word deserves to be returned to the thing it originally described, and Skugga’s farming is the thing it originally described.
This is not a marketing document. It is an account of how a farm in the highland forest of eastern Chiang Mai Province has been designed and managed to produce award-winning chocolate and specialty coffee from a biological system that grows more productive and more resilient with each passing year. For the traveller whose interest in ethical travel is genuine rather than performative, this is the evidence.
What permaculture actually means when it is not a marketing word
Permaculture was developed in the 1970s by Australian ecologists Bill Mollison and David Holmgren as a response to the destructive trajectory of industrial agriculture. The word is a contraction of permanent agriculture, or in its later formulation, permanent culture. The philosophy is built around three core ethics and a set of design principles derived from the observation of natural ecosystems.
The three ethics are: care for the earth (maintaining and increasing the health of living systems), care for people (ensuring that people have access to what they need), and fair share (redistributing surplus and limiting consumption to what is needed). These are ethical positions, not technical instructions. They operate as a framework within which specific design decisions are made.
The design principles, in David Holmgren’s formulation, include:
Observe and interact: spend time understanding the system before intervening
Catch and store energy: use natural flows of water, nutrients, and energy rather than fighting them
Obtain a yield: ensure the system produces something useful at every stage
Apply self-regulation and accept feedback: design systems that respond to their own imbalances
Use and value renewable resources: prefer biological solutions to mechanical and chemical ones
Produce no waste: the output of every element is the input of another
Design from patterns to details: understand large-scale patterns before addressing specifics
Integrate rather than segregate: design for relationships between elements, not for elements in isolation
Use small and slow solutions: prefer manageable complexity to large-scale simplification
Use and value diversity: multiple species, multiple functions, multiple connections make systems resilient
Use edges and value the marginal: the boundaries between systems are the most productive zones
Creatively use and respond to change: design for a changing world rather than against it
These principles are documented and explored in full at the Permaculture Research Institute, the primary global resource for permaculture design education.
The practical implication of these principles, applied to agricultural design, is a farm that looks very different from a conventional one. Rather than monocultures of a single crop managed with external inputs, a permaculture farm is a polyculture of multiple species arranged in designed relationships with each other, producing multiple outputs simultaneously from the same land. The farm is not a field with crops in it. It is a designed ecosystem with agricultural purposes.
Skugga Estate in Mae On is a designed ecosystem with agricultural purposes. Its specific design reflects both the permaculture principles above and the specific character of the Mae On highland environment: the geology, the climate, the existing forest ecology, and the agricultural history of the land on which the estate was established.
The Mae On site: what the permaculture design was working with
Every permaculture design begins with observation: the sustained, systematic attention to a specific site before any design decisions are made. What the designer observes includes the topography, the soil, the climate, the existing ecology, and the human context.
Topography
The highland terrain of the Mae On district is characterised by slopes rather than the flat agricultural plains of the Chiang Mai valley floor. Sloping land presents both a challenge (water moves quickly off slopes, removing topsoil and reducing infiltration) and an opportunity (slopes create microclimates, catch-and-store possibilities, and the potential for gravity-fed water distribution). The Skugga site was designed to work with the slope rather than against it: water from rainfall is directed into the soil rather than off the surface, contour-based planting reduces erosion, and the natural drainage patterns of the highland terrain are incorporated into the irrigation design.
Soil
The highland soils of the Mae On district are partly volcanic in origin, with a mineral complexity that reflects both the geological history of the Chiang Mai region and the centuries of forest ecosystem building that have deposited organic matter into the mineral substrate. The soil at the time of the estate’s establishment had the specific chemistry of highland forest soil: high in organic matter from leaf litter accumulation, with a microbial community developed over generations of undisturbed forest ecosystem function.
The permaculture approach to this soil was to protect and build it rather than exploit and replenish it. No tillage that would disrupt the microbial community. No synthetic inputs that would substitute for biological nutrient cycling. Active composting of all organic material from the farm and kitchen, returning it to the soil that produced it. Cover cropping and mulching to retain moisture and suppress weeds without chemicals.
Water
Mae On receives significant rainfall during the Thai rainy season (June to October), with the highland forest location receiving more than the valley floor. The challenge is not the total annual rainfall but its distribution: the majority falls in a five-month wet season, and the remaining seven months require water management to maintain crop health. The permaculture water design for Skugga focuses on infiltration (getting rainfall into the soil), storage (holding water in the landscape during the wet season), and distribution (moving stored water with minimum energy input).
Existing ecology
The Mae On site was not a degraded agricultural field when the estate was established. It was in or adjacent to highland forest that had been developing its ecological complexity for decades. The existing trees, the soil biology, the insect communities, the birds, and the specific microclimate produced by the forest canopy were all assets that the permaculture design could work with rather than against. The decision to maintain and extend the shade canopy rather than clear it for open cultivation was the single most important design decision the estate made.
The shade canopy: the architectural element that makes everything else possible
The shade canopy at Skugga Estate is not a landscaping feature. It is the architectural element of the farm’s permaculture design, the structure around which every other element of the agricultural system is organised.
Shade-grown agriculture is older than permaculture as a formal philosophy. The traditional agroforestry systems of tropical Southeast Asia, Central America, West Africa, and South Asia have been integrating tree canopies with productive crops for centuries, understanding empirically what agricultural science has subsequently documented: that a mixed-canopy agricultural system produces more from a given area of land, with less external input, than the same area managed as a monoculture.
Temperature moderation
The canopy intercepts solar radiation before it reaches the crop level, reducing the temperature at the cacao and coffee root zone by several degrees. This temperature moderation is one of the mechanisms through which shade-grown coffee develops more complex flavour than sun-grown: the cooler temperature slows cherry ripening, extending the period during which sugars and aromatic compounds develop in the bean. The same principle applies to shade-grown cacao.
Moisture retention
The canopy intercepts rainfall, reducing the kinetic energy of the rain before it reaches the soil surface. This matters because it is the kinetic energy of heavy tropical rainfall that compacts the surface, destroys soil structure, and initiates the runoff that removes topsoil from slopes. A canopy-covered soil surface allows rainfall to infiltrate rather than run off. The canopy also reduces evaporation from the soil surface by shading it from direct sun, maintaining soil moisture between rainfall events.
Nutrient cycling
The canopy trees produce leaf litter year-round: a continuous input of organic matter to the soil surface that is decomposed by the microbial community into the nutrients that the cacao, coffee, and other crops absorb through their roots. This is nitrogen, phosphorus, potassium, and the trace elements that conventional agriculture applies as synthetic fertiliser, delivered at the rate and in the chemical form that the soil biology and the crops can most efficiently use, generated entirely from within the system. The canopy is a slow-release fertiliser factory operating continuously without external input.
Pest and disease suppression
The diverse canopy creates habitat for the predators of agricultural pests: birds, spiders, parasitoid wasps, and other beneficial insects that control aphid, caterpillar, and other pest populations in the crop below. A monoculture provides no habitat for these predators and must replace their function with pesticides. The Skugga canopy provides the habitat, and the predator community it supports provides the pest control, generated internally rather than purchased externally.
Microclimate creation
The combined effect of temperature moderation, moisture retention, and the physical presence of the canopy trees creates a distinct microclimate within the estate’s cultivated area: cooler, more humid, and more stable in temperature than the surrounding open landscape. This microclimate is the growing environment that the estate’s cacao and coffee have adapted to and that produces their specific flavour character. It is not replicable by any means other than maintaining the canopy itself.
The soil management system: building rather than depleting
The soil management approach at Skugga Estate is built around a single principle: that the soil is a living system, not a growing medium. The distinction determines every practical decision about how the farm is managed.
A growing medium — the conventional industrial agriculture model — is a substrate in which crops are anchored while nutrients are supplied from external sources and biological competition is controlled through chemical intervention. The soil as growing medium can be degraded indefinitely, the degradation compensated for by increasing external inputs. The FAO’s State of the World’s Soil Resources documents this process globally: topsoil loss, soil compaction, salinisation from irrigation, and microbial community collapse are among the most serious and least discussed consequences of industrial agriculture.
A living system — the permaculture model — is a biological community in which the farm’s crops are participants rather than the only inhabitants. The soil microbial community, bacteria, fungi, protozoa, nematodes, and macro-organisms from earthworms to beetles, is the engine of nutrient cycling, water infiltration, disease suppression, and the physical structure that makes soil productive. This community is built over time by the addition of organic matter, minimal disturbance, the maintenance of root systems throughout the year, and the provision of biological diversity. It degrades quickly under tillage and synthetic chemicals. It builds slowly under the conditions that permaculture design provides.
Composting
All organic waste from the farm — cacao pod husks, coffee cherry pulp, kitchen food waste from the BarBQ Bistro and Roll Bar Bakery, garden clippings — is composted on site and returned to the soil. This closed-loop nutrient cycling means that the minerals and organic matter removed from the soil in the crops are returned to it in the compost, maintaining long-term fertility without external inputs. The cacao pod husk in particular is a significant composting material: the pod is large relative to the seed it contains, and composting all husks represents a substantial annual organic matter input to the soil.
Mulching
The soil surface under the cacao trees and around the coffee plants is kept covered with a layer of organic mulch: composted material, wood chips from pruning operations, or leaf litter raked from the canopy trees. Mulching serves three functions simultaneously: it suppresses weed growth without herbicides, it retains soil moisture by reducing evaporation from the soil surface, and it feeds the soil microbial community as it decomposes.
Cover cropping in the vineyard
The young vineyard planted in 2025 is managed with cover crops in the rows between vines: deliberately planted species that cover the soil surface, fix atmospheric nitrogen through root associations with nitrogen-fixing bacteria, prevent erosion from highland rainfall, and are either mown in place or incorporated into the soil when the nitrogen and organic matter they have built is needed by the vines. Cover cropping in vineyards is standard practice in the most ecologically aware wine production globally and is one of the most effective single interventions available for building soil health in a newly planted vineyard.
No synthetic inputs
No synthetic fertilisers, pesticides, herbicides, or fungicides are used on the estate. This is not a certification requirement — Skugga does not hold a formal organic certification, though its practices are consistent with what organic certification programmes require. It is a philosophical commitment: the belief that synthetic inputs, by substituting for the biological processes that a healthy soil ecosystem provides, undermine the long-term biological health that the farm is designed to build.
Minimal tillage
The soil at Skugga is disturbed as little as possible. Tillage damages soil structure, destroys the fungal networks (mycorrhizae) that connect plant roots to the soil mineral matrix, reduces soil aeration through compaction of the disturbed layer, and accelerates the oxidation of soil organic matter into carbon dioxide. The permaculture alternative is to allow the soil’s own biological activity — earthworms, roots, and the physical action of roots as they grow and die — to create and maintain soil structure without mechanical intervention.
Biodiversity as agricultural infrastructure
The permaculture principle that diversity is resilience is not a philosophical aspiration at Skugga Estate. It is a practical design criterion that shapes every decision about what is planted, where, and in what relationship to every other element of the farming system.
A monoculture is biologically simple and therefore biologically fragile. A single pest or disease adapted to the monoculture crop can move through the entire planting without encountering resistance. A single weather event that the monoculture is ill-suited to can destroy the entire crop. Industrial agriculture has responded to these fragilities with external inputs: pesticides, fungicides, crop insurance. These solutions work at cost, but they do not address the underlying fragility. They compensate for it repeatedly rather than designing it out.
The Skugga polyculture — comprising cacao, coffee, tea, avocado, macadamia, vineyard grapes, kitchen garden vegetables, orchard fruit, canopy trees, cover crops, and the unmanaged forest edges around the cultivated area — is biologically complex and therefore biologically resilient. The diversity also produces the specific characteristic of Skugga’s product quality: flavour complexity. The interaction between the shade canopy trees, the cacao below them, the coffee interspersed with both, and the soil microbial community sustained by all of them creates the specific chemical environment that produces the flavour notes that trained tasters can identify as Mae On highland origin.
The beehives
The beehives maintained on the cacao plantation at Skugga Estate are one of the most visible expressions of the biodiversity-as-infrastructure principle. The presence of a healthy bee population indicates a farm ecosystem with the floral diversity and absence of pesticide contamination that beneficial insects require. The bees actively pollinate coffee flowers, kitchen garden crops, and fruit trees, contributing directly to yields across the farm. The hives also produce estate honey as an additional product. Research from Bees for Development documents the role of beekeeping in tropical agricultural contexts, confirming the productivity gains that on-farm bee populations generate.
The forest edges
The boundaries between the cultivated areas of Skugga Estate and the surrounding highland forest are managed as productive zones rather than as barriers to be cleared. The forest edge habitat provides nesting habitat for insectivorous birds that control caterpillar and other crop pests, overwintering habitat for predatory insects that control aphid and mite populations, seed sources for the natural regeneration of canopy tree species in the cultivated area, and the visual and experiential transition between the farm and the natural landscape that makes Skugga Estate feel like part of the Mae On highland ecosystem rather than an intrusion into it.
Water management: catching, storing, and distributing what the highland receives
The Mae On highland receives adequate rainfall over the annual cycle. The challenge is temporal: the majority arrives in the wet season (June to October), and the crops need water in the dry season (November to May) when rainfall is minimal. The permaculture solution is not to drill a bore and pump groundwater — a solution that works short-term and depletes the aquifer long-term — but to catch and store as much of the wet season rainfall as possible in the landscape itself and distribute it with minimum energy input.
Infiltration maximisation
The mulched soil surface, the undisturbed soil structure, and the root channels created by the canopy trees and cover crops all maximise the proportion of rainfall that infiltrates into the soil rather than running off the surface. This is the most important water management intervention available to a highland farm on sloping terrain: every litre of rainfall that enters the soil is a litre that does not erode the topsoil and is available to the crops and the soil biology throughout the dry season.
Contour planting
The vine rows in the vineyard and the planting rows in the cacao and coffee areas are oriented along the contour of the slope — horizontal lines across the slope rather than vertical lines running down it. Contour planting slows the movement of water across the slope, giving it more time to infiltrate before reaching the bottom. It is one of the oldest and most effective water management techniques in highland agriculture and one of the clearest expressions of the permaculture principle of working with natural patterns rather than against them.
Irrigation precision
Where supplementary irrigation is used during the dry season, drip irrigation delivers water directly to the root zone of each plant at the rate and frequency the plant requires. Drip irrigation reduces water use by 30 to 50 percent compared to conventional methods while delivering more consistent moisture to the root zone and reducing the surface moisture that promotes fungal disease. It is also compatible with the minimal tillage approach because the system operates without soil disturbance.
Regenerative agriculture: the philosophy behind the practice
Regenerative agriculture is the term that has emerged in the past decade to describe farming systems designed to restore ecological function to agricultural land — or, in the case of farms like Skugga that were designed regeneratively from the start, to build ecological function continuously. The Regenerative Agriculture Foundation defines it as focused specifically on soil health, carbon sequestration, water cycle restoration, and biodiversity as the measures of agricultural system health. It is broader than organic agriculture (which focuses primarily on the avoidance of synthetic inputs) and more specific than permaculture (which is a design philosophy applicable beyond agriculture).
Long-running comparative research from the Rodale Institute documents the outcomes of regenerative versus conventional farming across decades of parallel trials. The results consistently show improvement in all measures of soil health under regenerative management and declining performance under conventional management.
Skugga Estate’s farming practices are regenerative in this specific sense. The soil at the estate, under nine years of organic management with no synthetic inputs, active composting, cover cropping, mulching, and minimal tillage, is more biologically active and more structurally healthy than it was when the estate was established. The carbon content of the soil is increasing rather than declining. The microbial community that drives nutrient cycling, disease suppression, and water infiltration is more diverse and more active than in a conventionally managed soil.
The quality of Skugga’s chocolate and coffee — the awards at international competitions, the recognition by trained tasters of the specific character of Mae On highland origin — is the agricultural output of this biological health. The Fine Chocolate Industry Association and the Specialty Coffee Association both document the relationship between agricultural practice and product quality. The permaculture design and the regenerative management are not separate from the quality of the product. They are the mechanism that produces it.
What a visit to Skugga Estate actually shows you
The traveller who chooses Skugga Estate as a destination — for a day trip, a workshop, a wedding, or a corporate retreat — is spending money and time at a farm that is genuinely doing what it says it is doing: building soil health, supporting biodiversity, managing water responsibly, and producing food and agricultural products of demonstrable quality from a biological system that improves with time.
This is the substance behind the word permaculture when it is used honestly. It is not the potted herb outside the kitchen door. It is nine years of consistent agricultural decision-making in the highland forest of Mae On, producing a farm that is more biologically productive in 2026 than it was in 2016, and that will be more productive still in 2036 — because the system is designed to compound its own biological capital rather than draw it down.
The visit is the verification. The farm tour shows the canopy and the composting and the cover crops and the beehives. The Chocolate Lab shows what the soil produces. The Coffee Roastery shows what the shade canopy does to a coffee bean. The BarBQ Bistro shows what the kitchen garden grows. The vineyard shows what nine years of soil building has produced for the newest and most ambitious crop on the estate.
The evidence is in the cup, the bar, and the plate. The permaculture design is what put it there.

FAQ section
What is permaculture farming and how is it different from organic farming?
Permaculture is a design philosophy for agricultural and human systems based on the patterns and relationships of natural ecosystems. It is broader than organic farming, which focuses primarily on avoiding synthetic inputs. Permaculture designs entire farming systems — the arrangement of crops, the management of water, the use of canopy trees, the integration of animals and insects, the cycling of nutrients — to function as self-sustaining biological systems that generate their own fertility, pest control, and water management from within. Organic farming can be applied to a conventional monoculture by removing the synthetic inputs. Permaculture redesigns the entire system from first principles.
What does regenerative agriculture mean at Skugga Estate specifically?
Regenerative agriculture at Skugga means that the farm’s management practices are designed to leave the soil, the water, and the ecosystem in better condition after farming than before. Specifically: no synthetic inputs, active composting of all organic waste returning nutrients to the soil, cover cropping in the vineyard to build soil biology, mulching to retain moisture and feed the soil microbial community, minimal tillage to preserve soil structure and fungal networks, and the maintenance of a shade canopy and forest edge habitat that supports biodiversity across the farm. The measurable outcome is increasing soil health over time rather than the declining soil health that conventional farming produces.
Is Skugga Estate certified organic?
Skugga Estate uses farming practices consistent with organic certification requirements — no synthetic pesticides, herbicides, or fertilisers — as a philosophical commitment rather than as a certification exercise. The farm is not formally certified by a third-party organic certification body. Guests who want to understand the specific farming practices in detail are welcome to discuss them directly with the estate team during a farm tour.
How does permaculture farming produce better chocolate and coffee?
The connection between farming practice and product quality is direct and measurable. Healthy soil, high in organic matter, biologically active, well-structured, provides crops with more complete and balanced mineral nutrition than degraded soil supplemented with synthetic fertiliser. This nutritional completeness translates into the aromatic and flavour compounds that make specialty chocolate and specialty coffee distinctive. The shade canopy that is central to Skugga’s permaculture design slows the ripening of both cacao pods and coffee cherries, extending the period during which flavour compounds develop in the fruit. The biodiversity of the farm’s ecosystem creates the specific microbial environment of the fermentation that determines chocolate flavour more than any other single process.
Can I see the permaculture farming practices during a visit to Skugga Estate?
Yes. The guided estate tour (1.5 hours, book 24 hours in advance) walks through the cacao and coffee plantations with explanation of the permaculture design: the shade canopy, the soil management practices, the beehives, the composting system, and the relationship between the farm’s biodiversity and the quality of its products. The tour includes a tasting flight of coffee and chocolate that connects the agricultural practices explained during the walk to the flavour of the finished products. Walk-in visits to the farm grounds, Chocolate Lab, Coffee Roastery, and BarBQ Bistro are free during estate hours.
How does Skugga Estate manage pests and diseases without chemicals?
Pest and disease management at Skugga relies on the biodiversity of the farm ecosystem rather than chemical intervention. The shade canopy and forest edges provide habitat for insectivorous birds and predatory insects that control agricultural pests biologically. Variety selection prioritises crops with natural resistance to the fungal diseases that the highland climate can produce. Canopy management maintains the air circulation and light penetration that reduce disease pressure in the cacao and coffee. Manual intervention is used where necessary. This approach requires more observation and more agricultural knowledge than chemical management but produces crops with none of the residual chemical input that synthetic pest management leaves in the harvest.
How long has Skugga Estate been farming with permaculture principles?
Skugga Estate was established in 2016 with the first coffee harvest and has used permaculture and regenerative farming principles from the beginning. The cacao was introduced in 2018 and the vineyard planted in 2025, with the same farming philosophy applied to each new crop. The farm’s soil, canopy, and biological systems have been developing under this management for nine years, which is long enough for measurable improvements in soil health, biodiversity, and crop quality to have accumulated.
What is the connection between permaculture farming and Skugga’s award-winning products?
The award-winning chocolate and specialty coffee that Skugga Estate produces are the direct agricultural output of the permaculture design. The specific flavour character of Mae On highland cacao and coffee — the mineral notes, the floral complexity, the origin-specific profile that trained tasters can identify and that has been recognised at international competitions — is produced by the combination of the highland volcanic soil, the shade canopy, the diurnal temperature variation, the on-site fermentation environment, and nine years of regenerative soil management. The permaculture is not separate from the quality. It is the mechanism that produces it.
