'{{Farming}} '''Permaculture''' is a system of [[Agriculture|agricultural]] and social design principles centered on simulating or directly utilizing the patterns and features observed in natural [[ecosystem]]s. Permaculture was developed, and the term coined by [[Bill Mollison]] and [[David Holmgren]] in 1968.<ref>Introduction to Permaculture, (1991), Mollison, p. v</ref> It has many branches that include but are not limited to [[ecological design]], [[ecological engineering]], [[environmental design]], [[construction]] and [[integrated water resources management]] that develops [[sustainable architecture]], regenerative and self-maintained [[habitat]] and agricultural systems modeled from natural ecosystems.{{Sfn | Hemenway | 2009 | p = [http://books.google.com/books?id=gxW0MGXha6cC&pg=PA5 5]}}<ref>{{cite book| last =Mars | first = Ross| title= The Basics of Permaculture Design|publisher=Chelsea Green |year=2005|isbn=978-1-85623-023-0|page=1|url = http://books.google.com/books?id=MWb6i-G6QAkC&pg=PA1}}</ref> Mollison has said: "Permaculture is a philosophy of working with, rather than against nature; of protracted and thoughtful observation rather than protracted and thoughtless labor; and of looking at plants and animals in all their functions, rather than treating any area as a [[Monocropping|single product system]]."<ref>Mollison, B.

This book inspired many individuals intent on making agriculture more sustainable, such as [[Toyohiko Kagawa]] who pioneered [[forest farming]] in [[Japan]] in the 1930s.{{Sfn | Hart| 1996|p = [http://books.google.co.uk/books?id=N01940btQAQC&lpg=PA41 41]}} The definition of permanent agriculture as that which can be sustained indefinitely was supported by Australian [[P. A. Yeomans]] in his 1964 book ''Water for Every Farm''. Yeomans introduced an observation-based approach to land use in Australia in the 1940s, and the [[keyline design]] as a way of managing the supply and distribution of water in the 1950s. [[Stewart Brand]]’s works were an early influence noted by Holmgren.<ref>{{cite web | title = The Essence of Permaculture | url = http://www.holmgren.com.au/frameset.html?http://www.holmgren.com.au/html/Writings/weeds.html | first = David | last = Holmgren | publisher= Holmgren Design Services |accessdate= 10 September 2011 |year=2006}}</ref> Other early influences include [[Ruth Stout]] and [[Esther Deans]], who pioneered [[no-dig gardening]], and [[Masanobu Fukuoka]] who, in the late 1930s in Japan, began advocating [[no-till]] orchards, gardens and [[natural farming]].<ref>{{cite news |title=The One-Straw Revolution by Masanobu Fukuoka |first=Bill |last=Mollison |newspaper=[[Nation Review]] |date=September 15–21, 1978 |page= 18}}</ref> ==Core tenets and principles of design== The three core tenets of permaculture are:<ref>{{Citation | last1 = Greenblott | first1 = Kara | first2 = Kristof | last2 = Nordin | year = 2012 | title = Permaculture Design for Orphans and Vulnerable Children Programming: Low-Cost, Sustainable Solutions for Food and Nutrition Insecure Communities | place = Arlington, VA | publisher = USAID | series = AIDS Support and Technical Assistance Resources, AIDSTAR-One | number = Task Order 1 | url = http://www.aidstar-one.com/focus_areas/ovc/resources/technical_briefs/permaculture_for_OVC}}.</ref>{{Sfn | Mollison | 1988 | p =2}}<ref>{{cite book |title = Permaculture: Principles & Pathways Beyond Sustainability |last=Holmgren |first=David |year=2002 |publisher=Holmgren Design Services |isbn = 0-646-41844-0 |page=1}}</ref> * '''''Care for the earth''''': Provision for all life systems to continue and multiply. This is the first principle, because without a healthy earth, [[human]]s cannot flourish. * '''''Care for the people''''': Provision for people to access those resources necessary for their existence. * '''''Return of surplus''''': Reinvesting surpluses back into the system to provide for the first two ethics. This includes returning waste back into the system to recycle into usefulness.<ref>{{cite web|last=Mollison|first=Bill|title=Permaculture: A Quiet Revolution | type = interview |url=http://www.scottlondon.com/interviews/mollison.html|work= Scott London |accessdate= 17 May 2013}}</ref> The third ethic is sometimes referred to as Fair Share to reflect that each of us should take no more than what we need before we reinvest the surplus. Permaculture design emphasizes patterns of [[landscape]], function, and species assemblies. It determines where these elements should be placed so they can provide maximum benefit to the local environment. The central concept of permaculture is maximizing useful connections between components and [[synergy]] of the final design. The focus of permaculture, therefore, is not on each separate element, but rather on the relationships created among elements by the way they are placed together; the whole becoming [[Emergence|greater than the sum of its parts]]. Permaculture design therefore seeks to minimize [[waste]], human labor, and energy input by building systems with maximal benefits between design elements to achieve a high level of [[synergy]]. Permaculture designs evolve over time by taking into account these relationships and elements and can become extremely complex systems that produce a high density of food and materials with minimal input.<ref name="Edible Forest Gardening">{{cite web|url=http://www.edibleforestgardens.com/|title=Edible Forest Gardening}}</ref> The design principles which are the conceptual foundation of permaculture were derived from the science of [[systems ecology]] and study of pre-industrial examples of [[sustainable]] land use. Permaculture draws from several disciplines including [[organic farming]], [[agroforestry]], [[integrated farming]], [[sustainable development]], and [[applied ecology]].<ref name="David Holmgren 1997">{{cite web | title = Weeds or Wild Nature | url = http://holmgren.com.au/wp-content/uploads/2013/02/23_weeds_or_wild_nature.pdf | first = David | last = Holmgren |publisher= Permaculture International Journal |accessdate= 10 September 2011 |year=1997}}</ref> Permaculture has been applied most commonly to the design of housing and landscaping, integrating techniques such as [[agroforestry]], [[natural building]], and [[rainwater harvesting]] within the context of permaculture design principles and theory. ==Theory== ===Twelve design principles=== Twelve Permaculture design principles articulated by David Holmgren in his ''Permaculture: Principles and Pathways Beyond Sustainability'':<ref>{{cite web|url=http://holmgren.com.au/product/principles/ |title=Permaculture: Principles and Pathways Beyond Sustainability |publisher=Holmgren Design |accessdate= 2013-10-21}}</ref> # ''Observe and interact'': By taking time to engage with nature we can design solutions that suit our particular situation. # ''Catch and store energy'': By developing systems that collect resources at peak abundance, we can use them in times of need. # ''Obtain a yield'': Ensure that you are getting truly useful rewards as part of the work that you are doing. # ''Apply self-regulation and accept feedback'': We need to discourage inappropriate activity to ensure that systems can continue to function well. # ''Use and value [[renewable]] resources and services'': Make the best use of nature's abundance to reduce our consumptive behavior and dependence on non-renewable resources. # ''Produce no waste'': By valuing and making use of all the resources that are available to us, nothing goes to waste. # ''Design from patterns to details'': By stepping back, we can observe patterns in nature and society. These can form the backbone of our designs, with the details filled in as we go. # ''Integrate rather than segregate'': By putting the right things in the right place, relationships develop between those things and they work together to support each other. # ''Use small and slow solutions'': Small and slow systems are easier to maintain than big ones, making better use of local resources and producing more sustainable outcomes. # ''Use and value diversity'': Diversity reduces vulnerability to a variety of threats and takes advantage of the unique nature of the environment in which it resides. # ''Use edges and value the marginal'': The interface between things is where the most interesting events take place. These are often the most valuable, diverse and productive elements in the system. # ''Creatively use and respond to change'': We can have a positive impact on inevitable change by carefully observing, and then intervening at the right time. ===Layers=== [[File:Claire Gregorys Permaculture garden.jpg|thumb|238px|Suburban permaculture garden in [[Sheffield]], UK with different layers of vegetation]] Layers are one of the tools used to design functional ecosystems that are both sustainable and of direct benefit to humans. A mature ecosystem has a huge number of relationships between its component parts: trees, [[understory]], [[ground cover]], [[soil]], [[fungi]], insects, and animals. Because plants grow to different heights, a diverse community of life is able to grow in a relatively small space, as the vegetation occupies different layers. There are generally seven recognized layers in a [[forest gardening|food forest]], although some practitioners also include [[fungi]] as an eighth layer.<ref name="tcpermaculture.com">{{Citation | url = http://tcpermaculture.com/site/2013/05/27/nine-layers-of-the-edible-forest-garden/ | title = Nine layers of the edible forest garden | date = May 27, 2013 | publisher = TC permaculture}}.</ref> # The [[canopy (biology)|canopy]]: the tallest trees in the system. Large trees dominate but typically do not saturate the area, i.e. there exist patches barren of trees. # [[Understory]] layer: trees that revel in the dappled light under the canopy. # [[Shrub layer]]: a diverse layer of woody perennials of limited height. includes most berry bushes. # [[Herbaceous layer]]: Plants in this layer die back to the ground every winter (if winters are cold enough, that is). They do not produce woody stems as the Shrub layer does. Many culinary and medicinal herbs are in this layer. A large variety of beneficial plants fall into this layer. May be annuals, biennials or perennials. # Soil surface/[[Groundcover]]: There is some overlap with the [[Herbaceous layer]] and the [[Groundcover layer]]; however plants in this layer grow much closer to the ground, grow densely to fill bare patches of soil, and often can tolerate some foot traffic. [[Cover crop]]s retain soil and lessen [[erosion]], along with [[green manure]]s that add nutrients and [[organic matter]] to the soil, especially [[Nitrogen fixation|nitrogen]]. # [[Rhizosphere (ecology)|Rhizosphere]]: Root layers within the soil. The major components of this layer are the soil and the organisms that live within it such as plant roots (including [[root crop]]s such as [[potato]]es and other edible [[tuber]]s), fungi, insects, nematodes, worms, etc. # Vertical layer: climbers or [[vine]]s, such as [[runner bean]]s and [[lima bean]]s (vine varieties).<ref name="tcpermaculture.com"/><ref>{{Citation | contribution-url = http://permacultureschool.ca/food-forests/seven-layers-of-a-forest/ | title = Food forests | contribution = Seven layers of a forest | publisher = Permaculture school | place = [[Canada|CA]]}}.</ref> ===Guilds=== There are many forms of guilds, including guilds of plants with similar functions (that could interchange within an ecosystem), but the most common perception is that of a mutual support guild. Such a [[Guild (ecology)|guild]] is a group of [[species]] where each provides a unique set of diverse functions that work in conjunction, or harmony. Mutual support guilds are groups of [[plant]]s, [[animal]]s, [[insect]]s, etc. that work well together. Some plants may be grown for food production, some have tap roots that draw nutrients up from deep in the soil, some are nitrogen-fixing [[legumes]], some attract [[beneficial insects]], and others repel harmful insects. When grouped together in a mutually beneficial arrangement, these plants form a guild. See Dave Jacke's work on edible forest gardens for more information on other guilds, specifically resource-partitioning and community-function guilds.<ref>{{cite journal|last1=Simberloff|first1=D|last2=Dayan|first2=T|title=The Guild Concept and the Structure of Ecological Communities|journal=Annual Review of Ecology and Systematics|volume=22|page=115|year=1991|doi=10.1146/annurev.es.22.110191.000555}}</ref><ref>{{cite web|url=http://www.britannica.com/eb/article-70591/community-ecology | work = Encyclopaedia Britannica | title = Guilds | accessdate=2011-10-21}}</ref><ref>{{cite journal|last1=Williams|first1=SE|last2=Hero|first2=JM|title=Rainforest frogs of the Australian Wet Tropics: guild classification and the ecological similarity of declining species|journal=Proceedings.

Permaculturists argue that, where vastly differing systems meet, there is an intense area of productivity and useful connections. An example of this is the coast; where the land and the sea meet there is a particularly rich area that meets a disproportionate percentage of human and animal needs. So this idea is played out in permacultural designs by using spirals in the herb garden or creating ponds that have wavy undulating shorelines rather than a simple circle or oval (thereby increasing the amount of edge for a given area).{{Citation needed |date=August 2015}} ===Zones=== [[File:Permaculture Zones.svg|thumb|Permaculture Zones 0-5.]] Zones are a way of intelligently organizing design elements in a human environment on the basis of the frequency of human use and plant or animal needs. Frequently manipulated or harvested elements of the design are located close to the house in zones 1 and 2. Less frequently used or manipulated elements, and elements that benefit from isolation (such as wild species) are farther away. Zones are about positioning things appropriately, and are numbered from 0 to 5.{{Sfn | Burnett | 2001}}{{Page needed |date=August 2015}} ; Zone 0: The house, or home center. Here permaculture principles would be applied in terms of aiming to reduce energy and water needs, harnessing natural resources such as sunlight, and generally creating a harmonious, sustainable environment in which to live and work. Zone 0 is an informal designation, which is not specifically defined in [[Bill Mollison]]’s book. ; Zone 1: The zone nearest to the house, the location for those elements in the system that require frequent attention, or that need to be visited often, such as salad crops, [[herb]] plants, soft fruit like [[Strawberry|strawberries]] or [[Raspberry|raspberries]], [[greenhouse]] and [[cold frame]]s, propagation area, [[Vermicompost|worm compost]] bin for kitchen waste, etc. [[Raised bed gardening|Raised beds]] are often used in zone 1 in [[Urban agriculture|urban areas]]. ; Zone 2: This area is used for siting [[perennial]] plants that require less frequent maintenance, such as occasional [[weed control]] or [[pruning]], including currant bushes and orchards, pumpkins, sweet potato, etc. This would also be a good place for [[beehive]]s, larger scale [[compost]]ing bins, and so on. ; Zone 3: The area where main-crops are grown, both for domestic use and for trade purposes. After establishment, care and maintenance required are fairly minimal (provided [[mulch]]es and similar things are used), such as watering or weed control maybe once a week. ; Zone 4: A semi-wild area. This zone is mainly used for [[forage]] and collecting wild food as well as production of timber for construction or firewood. ; Zone 5: A wilderness area. There is no human intervention in zone 5 apart from the observation of natural [[ecosystem]]s and cycles. Through this zone we [[Biological pest control|build up a natural reserve of bacteria, moulds and insects]] that can aid the zones above it.<ref>{{Citation | url = http://edepot.wur.nl/115721 | title = Permacultuur course | publisher = WUR | place = [[Netherlands|NL]]}}.</ref> ===People and permaculture=== Permaculture uses observation of nature to create regenerative systems, and the place where this has been most visible has been on the landscape. There has been a growing awareness though that firstly, there is the need to pay more attention to the peoplecare ethic, as it is often the dynamics of people that can interfere with projects, and secondly that the principles of permaculture can be used as effectively to create vibrant, healthy and productive people and communities as they have been in landscapes. ===Domesticated animals=== [[List of domesticated animals|Domesticated animals]] are often incorporated into site design.{{Sfn | Mollison| 1988|p =5| ps =: ‘[[Deer]], [[rabbit]]s, [[sheep]], and [[herbivorous]] [[fish]] are very useful to us, in that they convert unusable herbage to acceptable human food. Animals represent a valid method of storing inedible vegetation as food.’}} ==Common practices== ===Agroforestry=== [[Agroforestry]] is an integrated approach of using the interactive benefits from combining trees and shrubs with crops and/or livestock. It combines agricultural and [[forestry]] technologies to create more diverse, productive, profitable, healthy and sustainable land-use systems.<ref>{{cite web|url=http://nac.unl.edu |title=USDA National Agroforestry Center (NAC) |publisher=UNL |date=2011-08-01 |accessdate=2011-10-21}}</ref> In agroforestry systems, trees or shrubs are intentionally used within agricultural systems, or [[non-timber forest product]]s are cultured in forest settings.{{citation needed|date=June 2012}} [[Forest gardening]] is a term permaculturalists use to describe systems designed to mimic natural forests. Forest gardens, like other permaculture designs, incorporate processes and relationships that the designers understand to be valuable in natural ecosystems. The terms forest garden and food forest are used interchangeably in the permaculture literature. Numerous permaculturists are proponents of forest gardens, such as Graham Bell, [[Patrick Whitefield]], Dave Jacke, Eric Toensmeier and [[Geoff Lawton]]. Bell started building his forest garden in 1991 and wrote the book ''The Permaculture Garden'' in 1995, Whitefield wrote the book ''How to Make a Forest Garden'' in 2002, Jacke and Toensmeier co-authored the two volume book set ''Edible Forest Gardening'' in 2005, and Lawton presented the film ''Establishing a Food Forest'' in 2008.<ref name="Edible Forest Gardening"/><ref>{{cite web|url=http://permaculture.mediamice.net/?page_id=26| work = Permaculture | title=Graham Bell’s Forest Garden | publisher = Media mice}}</ref><ref>{{cite web| publisher = Transition culture | url=http://transitionculture.org/2009/02/11/film-review-%E2%80%9Cestablishing-a-food-forest-the-permaculture-way-series/| date = Feb 11, 2009 | title= Establishing a Food Forest | type = film review}}</ref> Tree Gardens, such as Kandyan tree gardens, in South and Southeast Asia, are often hundreds of years old. Whether they derived initially from experiences of cultivation and forestry, as is the case in agroforestry, or whether they derived from an understanding of forest ecosystems, as is the case for permaculture systems, is not self-evident. Many studies of these systems, especially those that predate the term permaculture, consider these systems to be forms of agroforestry. Permaculturalists who include existing and ancient systems of polycropping with woody species as examples of food forests may obscure the distinction between permaculture and agroforestry. Food forests and agroforestry are parallel approaches that sometimes lead to similar designs. ===Hügelkultur=== [[Hügelkultur]] is the practice of burying large volumes of wood to increase soil water retention. The porous structure of wood acts as a sponge when decomposing underground. During the rainy season, masses of buried wood can absorb enough water to sustain crops through the dry season.<ref>Wheaton, Paul.

Retrieved 2012-07-15.</ref> ===Natural building=== A [[natural building]] involves a range of [[building]] systems and materials that place major emphasis on sustainability. Ways of achieving sustainability through natural building focus on durability and the use of minimally processed, plentiful or [[renewable resource]]s, as well as those that, while [[Recycling|recycled]] or salvaged, produce healthy living environments and maintain indoor air quality. The basis of natural building is the need to lessen the [[natural environment|environmental]] impact of buildings and other supporting systems, without sacrificing comfort, health or [[aesthetics]]. To be more sustainable, natural building uses primarily abundantly available, renewable, reused or recycled materials. In addition to relying on natural building materials, the emphasis on the architectural design is heightened. The orientation of a building, the utilization of local climate and site conditions, the emphasis on natural ventilation through design, fundamentally lessen operational costs and positively impact the environment. Building compactly and minimizing the [[ecological footprint]] is common, as are on-site handling of energy acquisition, on-site water capture, alternate sewage treatment and water reuse.{{citation needed|date=June 2012}} ===Rainwater harvesting=== [[Rainwater harvesting]] is the accumulating and storing of rainwater for reuse before it reaches the [[aquifer]].<ref name="Rainwater harvesting">{{cite web| url= http://aramo.de/rain.html |title= Rainwater harvesting |year= 2012 | place = [[Germany|DE]] | publisher = Aramo | accessdate = 2012}}</ref> It has been used to provide [[drinking water]], water for [[livestock]], water for [[irrigation]], as well as other typical uses. Rainwater collected from the roofs of houses and local institutions can make an important contribution to the availability of drinking water. It can supplement the subsoil water level and increase urban greenery. Water collected from the ground, sometimes from areas which are especially prepared for this purpose, is called [[stormwater harvesting]].{{citation needed |date=June 2012}} [[Greywater]] is [[wastewater]] generated from domestic activities such as laundry, dishwashing, and bathing, which can be recycled on-site for uses such as landscape irrigation and [[constructed wetland]]s. Greywater is largely sterile, but not potable (drinkable). Greywater differs from water from the toilets which is designated [[sewage]] or [[Blackwater (waste)|blackwater]], to indicate it contains [[human waste]]. Blackwater is septic or otherwise toxic and cannot easily be reused. There are, however, continuing efforts to make use of blackwater or human waste. The most notable is for composting through a process known as humanure; a combination of the words human and manure. Additionally, the methane in humanure can be collected and used similar to natural gas as a fuel, such as for heating or cooking, and is commonly referred to as biogas. Biogas can be harvested from the human waste and the remainder still used as humanure. Some of the simplest forms of humanure use include a composting toilet or an outhouse or dry bog surrounded by trees that are heavy feeders which can be coppiced for wood fuel. This process eliminates the use of a standard toilet with plumbing.{{Citation needed |date=August 2015}} ===Sheet mulching=== In agriculture and [[gardening]], mulch is a protective cover placed over the soil. Any material or combination can be used as mulch, such as stones, leaves, cardboard, wood chips, gravel, etc., though in permaculture mulches of organic material are the most common because they perform more functions. These include: absorbing rainfall, reducing evaporation, providing nutrients, increasing organic matter in the soil, feeding and creating habitat for soil organisms, suppressing weed growth and seed germination, moderating diurnal temperature swings, protecting against frost, and reducing erosion. [[Sheet mulching]] is an agricultural no-dig gardening technique that attempts to mimic natural processes occurring within [[forest]]s. Sheet mulching mimics the leaf cover that is found on forest floors. When deployed properly and in combination with other Permacultural principles, it can generate healthy, productive and low maintenance ecosystems.<ref name="agroforestry">{{cite web| url = http://www.agroforestry.net/pubs/Sheet_Mulching.html |title=Sheet Mulching: Greater Plant and Soil Health for Less Work |publisher=Agroforestry |date= 2011-09-03 |accessdate= 2011-10-21}}</ref><ref name= "mason">{{Citation | title = Sustainable Agriculture | first = J | last = Mason | publisher = Landlinks | year = 2003}}.</ref>{{Page needed |date=August 2015}} Sheet mulch serves as a "nutrient bank," storing the nutrients contained in organic matter and slowly making these nutrients available to plants as the organic matter slowly and naturally breaks down. It also improves the soil by attracting and feeding [[earthworms]], [[woodlouse|slaters]] and many other soil micro-organisms, as well as adding [[humus]]. Earthworms "till" the soil, and their [[worm castings]] are among the best fertilizers and [[soil conditioner]]s. Sheet mulching can be used to reduce or eliminate undesirable plants by starving them of light, and can be more advantageous than using [[herbicide]] or other methods of control.{{citation needed|date=June 2012}} ===Intensive rotational grazing=== Grazing has long been blamed for much of the destruction we see in the environment. However, it has been shown that when grazing is modeled after nature, the opposite effect can be seen.<ref>{{cite web|title=Prince Charles sends a message to IUCN's World Conservation Congress|url=http://www.iucn.org/knowledge/multimedia/video/?10774/Prince-Charles-sends-a-message-to-IUCNs-World-Conservation-Congress|work=International Union for Conservation of Nature|accessdate=6 April 2013}}</ref><ref>{{cite web|last=Undersander|first=Dan|title=Grassland birds: Fostering habitat using rotational grazing|url=http://learningstore.uwex.edu/assets/pdfs/a3715.pdf|publisher=University of Wisconsin-Extension|accessdate=5 April 2013|display-authors=etal}}</ref> Also known as cell grazing, [[managed intensive rotational grazing]] (MIRG) is a system of grazing in which ruminant and non-ruminant herds and/or flocks are regularly and systematically moved to fresh pasture, range, or forest with the intent to maximize the quality and quantity of forage growth. This disturbance is then followed by a period of rest which allows new growth. MIRG can be used with cattle, sheep, goats, pigs, chickens, rabbits, geese, turkeys, ducks and other animals depending on the natural [[ecological community]] that is being mimicked. [[Sepp Holzer]] and [[Joel Salatin]] have shown how the disturbance caused by the animals can be the spark needed to start [[ecological succession]] or prepare ground for planting. [[Allan Savory]]'s [[holistic management]] technique has been likened to "a permaculture approach to [[rangeland management]]".<ref>{{cite book| title=Meat: A Benign Extravagance | first=Simon | last= Fairlie | publisher= Chelsea Green | year= 2010 |isbn= 978-1-60358325-1 | pages = 191–93}}</ref><ref>{{cite web|last=Bradley|first=Kirsten|title=Holistic Management: Herbivores, Hats, and Hope|url=http://milkwood.net/2010/04/27/holistic_management_herbivores_hats_and_hope/|publisher=Milkwood|accessdate=25 March 2014}}</ref> One variation on MIRG that is gaining rapid popularity is called eco-grazing.

He has successfully grown several varieties of fruiting trees at altitudes (approximately {{convert |9000|ft|m}}) far above their normal altitude, temperature, and snow load ranges. He notes that the Hügelkultur berms kept and/or generated enough heat to allow the roots to survive during alpine winter conditions. The point of having unpruned branches, he notes, was that the longer (more naturally formed) branches bend over under the snow load until they touched the ground, thus forming a natural arch against snow loads that would break a shorter, pruned, branch.{{citation needed|date=February 2015}} ===Compost management=== [[File:Compost Basket.jpg|thumb|Compost Basket]] Compost Basket is a way to the permanent management of compost materials. The idea of Compost Basket comes from Gyulai Iván. He invented and used it in the Gömörszőlős Educational Center. The inner circle is 1 meter deep. This is the place where compost material are put in. Under this is the outer circle, 40&nbsp;cm deep. Here the nutrients come down. ===Mollison and Holmgren=== [[File:Bill Mollison 01.jpg|thumb|right|[[Bill Mollison]] in January 2008.]] In the late 1960s, Bill Mollison and David Holmgren started developing ideas about stable agricultural systems on the southern Australian island state of [[Tasmania]]. This was a result of the danger of the rapidly growing use of industrial-agricultural methods. In their view, <ref>''Introduction to Permaculture'', 1991, Mollison, p.v</ref> these methods were highly dependent on non-renewable resources, and were additionally poisoning land and water, reducing [[biodiversity]], and removing billions of tons of [[topsoil]] from previously fertile landscapes. A design approach called ''permaculture'' was their response and was first made public with the publication of their book ''Permaculture One'' in 1978.<ref>''Introduction to Permaculture'', 1991, Mollison, p.v</ref> By the early 1980s, the concept had broadened from agricultural systems design towards [[Sustainable habitat|sustainable human habitats]]. After ''Permaculture One'', Mollison further refined and developed the ideas by designing hundreds of permaculture sites and writing more detailed books, notably ''Permaculture: A Designers Manual''. Mollison lectured in over 80 countries and taught his two-week Permaculture Design Course (PDC) to many hundreds of students. {{citation needed|date=June 2012}}Mollison "encouraged graduates to become teachers themselves and set up their own institutes and demonstration sites. This multiplier effect was critical to permaculture’s rapid expansion."<ref>{{cite web| last1 = Lillington| first1 = Ian| last2 = Holmgren | first2 = David |last3=Francis|first3=Robyn|last4=Rosenfeldt|first4= Robyn|title= The Permaculture Story: From ‘Rugged Individuals’ to a Million Member Movement|url= https://www.pipmagazine.com.au/wp-content/uploads/2014/10/what-is-permaculture.pdf | format = PDF | work =Pip Magazine|accessdate=9 July 2015}}</ref> In 1991, a four-part television documentary by ABC productions called "The Global Gardener" showed permaculture applied to a range of worldwide situations, bringing the concept to a much broader public.{{citation needed| date=June 2012}} In 2012, the UMass Permaculture Initiative won the White House "Champions of Change" sustainability contest, which declared that "they demonstrate how permaculture can feed a growing population in an environmentally sustainable and socially responsible manner".<ref>{{cite news | date = Mar 13, 2012 | title=UMass Amherst permaculture project wins White House award| newspaper = Boston | url=http://www.boston.com/2012/03/13/champion/r2XazdAkdr4SrYpzQWBT7K/story.html}}</ref> In 1997, Holmgren explained that the primary agenda of the permaculture movement is to assist people to become more self-reliant through the design and development of productive and sustainable gardens and farms.<ref name="David Holmgren 1997"/> In 2014, Holmgren endorsed and helped launch a new Australian permaculture magazine, Pip Magazine.<ref>{{cite web|title=Pip Launches to Great Success|url=https://www.pipmagazine.com.au/pip-launches-to-great-success/| work =Pip Magazine|accessdate=1 July 2015}}</ref> ==Notable permaculturists== Joseph Russell Smith took up an antecedent term as the subtitle for ''Tree Crops: A Permanent Agriculture'', a book in which he summed up his long experience experimenting with fruits and nuts as crops for human food and animal feed. By that year (1929), Smith saw the world as an interrelated whole and suggested mixed systems of trees and crops underneath. This book, along with the work of [[P. A. Yeomans]] (the latter created the [[keyline design]] concept), inspired many individuals intent on making permaculture a valid means of sustainable food production. [[Bill Mollison]] and [[David Holmgren]] developed it further, and permaculturists were trained under the umbrella of Bill Mollison's train the trainer system. Among some of the more recognizable names who received their original training within Mollison's PDC system would include [[Geoff Lawton]] and [[Toby Hemenway]], each of whom have more than 25 years experience teaching and promoting permaculture as a sustainable way of growing food. Simon Fjell was a Founding Director of the Permaculture Institute in late 1979, over 40 years experience, having first met Mollison in 1976. He has since worked in every continent. The permaculture movement also spread throughout Asia and Central America, with Hong Kong-based [https://daforum.wordpress.com/aisa/ Asian Institute of Sustainable Architecture (AISA)], Rony Lec leading the foundation of the [http://imapermaculture.org Mesoamerican Permaculture Institute (IMAP)] in Guatemala and Juan Rojas co-founding the [http://permacultura.com.sv Permaculture Institute of El Salvador]. ==Trademark and copyright issues== There has been contention over who, if anyone, controls legal rights to the word ''permaculture'': is it [[trademark]]ed or [[copyright]]ed? and if so, who holds the legal rights to the use of the word? For a long time Bill Mollison claimed to have copyrighted the word, and his books said on the [[copyright page]], "The contents of this book and the word PERMACULTURE are copyright." These statements were largely accepted at face-value within the permaculture community. However, copyright law does not protect names, ideas, concepts, systems, or methods of doing something; it only protects the expression or the description of an idea, not the idea itself. Eventually Mollison acknowledged that he was mistaken and that no copyright protection existed for the word ''permaculture''.<ref>{{cite web | title = The Permaculture Papers 5: time of change and challenge — 2000-2004 | url = http://pacific-edge.info/the-permaculture-papers-5-time-of-change-and-challenge-%E2%80%94-2000-2004/ | first = Russ | last = Grayson | publisher= Pacific edge |accessdate=8 September 2011 |year=2011}}</ref> In 2000, Mollison's US based Permaculture Institute sought a [[service mark]] (a form of trademark) for the word ''permaculture'' when used in educational services such as conducting classes, seminars, or workshops.<ref>{{cite web | title =Trademark Electronic Search System (TESS)| url = http://tess2.uspto.gov/bin/showfield?f=doc&state=4005:o81il1.2.1 |author= [[United States Patent and Trademark Office]] |publisher= US Department of Commerce |accessdate=8 September 2011|year= 2011}}</ref> The service mark would have allowed Mollison and his two Permaculture Institutes (one in the US and one in Australia) to set enforceable guidelines regarding how permaculture could be taught and who could teach it, particularly with relation to the PDC, despite the fact that he had instituted a system of certification of teachers to teach the PDC in 1993. The service mark failed and was abandoned in 2001. Also in 2001 Mollison applied for trademarks in Australia for the terms "Permaculture Design Course"<ref name="IPA">{{cite web | title = Result | url = http://pericles.ipaustralia.gov.au/atmoss/Falcon.Result |publisher =[[IP Australia]] |accessdate=8 September 2011| year=2011}}</ref> and "Permaculture Design".<ref name ="IPA"/> These applications were both withdrawn in 2003.
