Agroecology is a promising alternative to industrial agriculture, with the potential to avoid the negative social and ecological consequences of input-intensive production. Transitioning to agroecological production is, however, a complex project that requires diverse contributions from the outside of scientific institutions. Agroecologists therefore collaborate with traditional producers and agroecological movements. Permaculture is one such agroecological movement, with a broad international distribution and a unique approach to system design. Despite a high public profile, permaculture has remained relatively isolated from scientific research. Though the potential contribution of permaculture to agroecological transition is great, it is limited by this isolation from science, as well as from oversimplifying claims, and the lack of a clear definition. Here, we review scientific and popular permaculture literature. A systematic review discusses quantitative bibliometric data, including keyword analysis. A qualitative review identifies and assesses major themes, proposals, and claims. The manuscript follows a stratified definition of permaculture as design system, best practice framework, worldview, and movement. The major points of our analysis are as follows: (1) Principles and topics largely complement and even extend principles and topics found in the agroecological literature. (2) Distinctive approaches to perennial polyculture, water management, and the importance of agroecosystem configuration exceed what is documented in the scientific literature and thus suggest promising avenues of inquiry. (3) Discussions of practice consistently underplay the complexity, challenges, and risks that producers face in developing diversified and integrated production systems. (4) The movement is mobilizing diverse forms of social support for sustainability, in geographically diverse locations. (5) And scholarship in permaculture has always been a diverse marginal sector, but is growing.
ABSTRACT. Grassroots networks and social movements are increasingly regarded as agents of change that can help respond to environmental degradation both by generating novel solutions to existing problems and influencing institutions toward more substantive responses. We examine permaculture, an international movement that, despite its broad international distribution and relatively high public profile, has received little systematic scrutiny in the scientific literature. We attempt to remedy that gap by conducting a broad international (though English-only) survey of 731 permaculture participants, and assessing the socio-demographic characteristics of the movement. The survey examined self-identified roles of permaculture participants and explored the relationships between those roles and socio-demographic factors race, gender, and socioeconomic status. The influence of structural factors on participant roles was examined by including multidimensional national indices development, inequality, and ecosystem vitality, for the 45 countries in the sample. Results showed the participation of women at or above parity (53%), while participation by race showed a white supermajority (96%). Multivariate regression demonstrated that race, gender, and socioeconomic status are shaping participation in distinct ways and that each interact with structural factors. The effects of gender on social roles varied with ecosystem vitality, with women scoring higher than men in countries with high levels of ecosystem vitality, and the reverse where ecosystem vitality was low. The observed effect of race on practice varied with national inequality, such that the scores of respondents of color were equivalent to white respondents in countries with the least inequality, but descended as inequality increased, while whites were unaffected. Different indicators of socioeconomic status depressed and amplified different dimensions of participation. Results point toward a theoretical framework that identifies multiple levels and sites through which socio-demographic factors shape participation in grassroots environmental action, and the outlines of such a framework are discussed.
Permaculture is an international grassroots network founded in Australia in the late 1970s that focuses on the sustainable design of human settlement. This decentralized and little institutionalized movement disseminates a distinct worldview, design system, and set of associated practices. Permaculture's central concept is that humanity can reduce or replace energy and pollution-intensive industrial technologies, especially in agriculture, through intensive use of biological resources and thoughtful, holistic, design, patterned after natural ecosystems. To create autonomous, resilient, and equitable living spaces permaculture proposes pragmatic methodological principles informed by scientific ecology, traditional indigenous knowledge, observation, and experimentation. In the design of farming systems, permaculturists promote complex multi-strata polycultures involving perennial plants, crop-animal integration, high levels of habitat diversity, whole-landscape water management, and sustainable on-site energy production. Beyond scientifically-informed ecological design, permaculture encourages practitioners to develop emotional and subjective links with the earth, and develop their imagination and creativity as valuable parts of the design process. The originality and specificity of permaculture are discussed, along with critics, controversies and research perspectives.
The relationship between diversification and labor productivity is a pressing issue for diversified farming systems (DFS), which must compete with the high labor productivity of specialized and mechanized industrial farming systems. Synergies between multiple production systems represent an alternative pathway for enhancing labor productivity, contrasting with the economies of scale achieved by industrial farming. Facing a lack of technical and institutional support for managing diversified systems, DFS turn to grassroots agroecological networks for support. Permaculture is a grassroots network with an emphasis on diversified production that—despite its international scope and high public profile—has received little scholarly attention. In this exploratory study we assessed the relationship between diversification, labor productivity and involvement with permaculture, using data from 196 enterprises (i.e., distinct sources of income or aspects of a farm business) on 36 permaculture farms in the USA. We characterized diversification in two ways: by income at the level of the whole farm, and by labor for production enterprises only. By fitting a multilevel model of labor productivity (enterprises nested within farms) we assessed the evidence for synergies in production, i.e., positive relationships between diversification and returns to labor. Results indicated that both production diversity and level of involvement in the permaculture network had significant positive effects on labor productivity. This effect disappeared, however, when both diversity and participation were at their highest levels. Results also indicate that high levels of diversification shift tree crops from the lowest labor productivity of any type of production enterprise to the highest. Through this first ever (to our knowledge) systematic investigation of permaculture farms, our results provide support for the presence of production synergies in DFS, and for the role of permaculture in helping farmers achieve these synergies.
