Description
Self-sustainability is a type of sustainable living in which nothing is consumed other than what is produced by the self-sufficient individuals. Examples of attempts at self-sufficiency in North America include simple living, food storage, homesteading, off-the-grid, survivalism, DIY ethic, and the back-to-the-land movement.
Practices that enable or aid self-sustainability include autonomous building, permaculture, sustainable agriculture, and renewable energy. The term is also applied to limited forms of self-sustainability, for example growing one's own food or becoming economically independent of state subsidies. The self-sustainability of an electrical installation measures its degree of grid independence and is defined as the ratio between the amount of locally produced energy that is locally consumed, either directly or after storage, and the total consumption. [2]
A system is self-sustaining (or self-sufficient) if it can maintain itself by independent effort. The system self-sustainability is:
- the degree at which the system can sustain itself without external support
- the fraction of time in which the system is self-sustaining
Self-sustainability is considered one of the "ilities" and is closely related to sustainability and availability. In the economics literature, a system that has the quality of being self-sustaining is also referred to as an autarky.
An autonomous building is a building designed to be operated independently from infrastructural support services such as the electric power grid, gas grid, municipal water systems, sewage treatment systems, storm drains, communication services, and in some cases, public roads.
Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic. Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms.
Autarky is the characteristic of self-sufficiency, usually applied to societies, communities, states, and their economic systems.
An ecovillage is a traditional or intentional community with the goal of becoming more socially, culturally, economically, and/or ecologically sustainable. An ecovillage strives to produce the least possible negative impact on the natural environment through intentional physical design and resident behavior choices. It is consciously designed through locally owned, participatory processes to regenerate and restore its social and natural environments. Most range from a population of 50 to 250 individuals, although some are smaller, and traditional ecovillages are often much larger. Larger ecovillages often exist as networks of smaller sub-communities. Some ecovillages have grown through like-minded individuals, families, or other small groups—who are not members, at least at the outset—settling on the ecovillage's periphery and participating de facto in the community. There are currently more than 10,000 ecovillages around the world.
Independence is a condition of a nation, country, or state, in which residents and population, or some portion thereof, exercise self-government, and usually sovereignty, over its territory. The opposite of independence is the status of a dependent territory or colony. The commemoration of the independence day of a country or nation celebrates when a country is free from all forms of colonialism; free to build a country or nation without any interference from other nations.
Simple living refers to practices that promote simplicity in one's lifestyle. Common practices of simple living include reducing the number of possessions one owns, depending less on technology and services, and spending less money. In addition to such external changes, simple living also reflects a person's mindset and values. Simple living practices can be seen in history, religion, art, and economics.
Sustainable living describes a lifestyle that attempts to reduce the use of Earth's natural resources by an individual or society. Its practitioners often attempt to reduce their ecological footprint by altering their home designs and methods of transportation, energy consumption and diet. Its proponents aim to conduct their lives in ways that are consistent with sustainability, naturally balanced, and respectful of humanity's symbiotic relationship with the Earth's natural ecology. The practice and general philosophy of ecological living closely follows the overall principles of sustainable development.
Homesteading is a lifestyle of self-sufficiency. It is characterized by subsistence agriculture, home preservation of food, and may also involve the small scale production of textiles, clothing, and craft work for household use or sale. Pursued in different ways around the world—and in different historical eras—homesteading is generally differentiated from rural village or commune living by isolation of the homestead. Use of the term in the United States dates back to the Homestead Act (1862) and before. In sub-Saharan Africa, particularly in nations formerly controlled by the British Empire, a homestead is the household compound for a single extended family. In the UK the terms smallholder and croft are rough synonyms of homesteader.
A back-to-the-land movement is any of various agrarian movements across different historical periods. The common thread is a call for people to take up smallholding and to grow food from the land with an emphasis on a greater degree of self-sufficiency, autonomy, and local community than found in a prevailing industrial or postindustrial way of life. There have been a variety of motives behind such movements, such as social reform, land reform, and civilian war efforts. Groups involved have included political reformers, counterculture hippies, and religious separatists.
A prosumer is an individual who both consumes and produces. The term is a portmanteau of the words producer and consumer. Research has identified six types of prosumers: DIY prosumers, self-service prosumers, customizing prosumers, collaborative prosumers, monetised prosumers, and economic prosumers.
Peer production is a way of producing goods and services that relies on self-organizing communities of individuals. In such communities, the labor of many people is coordinated towards a shared outcome.
Off-the-grid or off-grid is a characteristic of buildings and a lifestyle designed in an independent manner without reliance on one or more public utilities. The term "off-the-grid" traditionally refers to not being connected to the electrical grid, but can also include other utilities like water, gas, and sewer systems, and can scale from residential homes to small communities. Off-the-grid living allows for buildings and people to be self-sufficient, which is advantageous in isolated locations where normal utilities cannot reach and is attractive to those who want to reduce environmental impact and cost of living. Generally, an off-grid building must be able to supply energy and potable water for itself, as well as manage food, waste and wastewater.
Ecological sufficiency, or simply sufficiency, refers to the concept or strategy to reduce the environmental footprint of societies through moderating the need for energy, carbon and material-based services and products. The term was popularised by authors such as Thomas Princen, a professor at MIT, in his 2005 book The Logic of Sufficiency. As a goal, sufficiency is about ensuring that all humans can live a good life within planetary boundaries, meaning without overshooting the ecological limits of the Earth and thus limiting resource use and pollution. Princen argues that "seeking enough when more is possible is both intuitive and rational – personally, organizationally and ecologically. And under global ecological constraint, it is ethical."
Modular self-reconfiguring robotic systems or self-reconfigurable modular robots are autonomous kinematic machines with variable morphology. Beyond conventional actuation, sensing and control typically found in fixed-morphology robots, self-reconfiguring robots are also able to deliberately change their own shape by rearranging the connectivity of their parts, in order to adapt to new circumstances, perform new tasks, or recover from damage.
Energy independence is independence or autarky regarding energy resources, energy supply and/or energy generation by the energy industry.
Jules C. Dervaes, Jr. was an urban farmer and a proponent of the urban homesteading movement. Dervaes and his three adult children operated an urban market garden in Pasadena, California, as well as other websites and online stores related to self-sufficiency and "adapting in place."
Autarky can be defined as the quality of being self-sufficient, thus energy-autarkic habitats are human dwellings which are independent concerning energy consumption for living. This may be based on resource efficiency, choice of building materials, living space, and so forth. Autonomic habitats are similar but reflect the fact that the person desires to act morally solely for the sake of doing "good", independently of other incentives. Subsistence agriculture can be considered a form of autarkic living. With the advent of industrialization networks for energy were set up, which led to dependency, but made life easier in many respects. Autarkic living can be seen as a trend "back to the roots": using renewable energy and being independent of coal, gas and oil.
Sustainable implant is an urban typology that acts as a decentralized infrastructure provision hub on the neighborhood or district scale. Sustainable implants provide integrated infrastructure services that maintain cycles of energy, water and material, as well as provides social and economic returns. The concept originates from Arjan van Timmeren’s research, Autonomy & Heteronomy (2006), as an answer to the problem of scale versus innovation in infrastructure; wherein infrastructure benefits from increasing returns to scale but suffer from extremely slow rate of change and turnover. To answer this problem, the sustainable implant is an instrument for mid-scale facilitation of alternative system innovation. The sustainable implant is a synthesis of techniques for sustainable processing of urban flows within an ecological processing device. The objective of a sustainable implant is to generate qualitative and quantitative improvements for utility service provision.
In electric power distribution, a fractalgrid is a system-of-systems architecture of distributed energy resources or DERs. In a fractalgrid topology, multiple microgrids are strategically arranged to follow a fractal or recursive pattern. Fractals, or self-similar patterns, can be seen in nature. Clouds, river networks, and lightning bolts are a few examples of natural phenomena that display fractal features. In a fractalgrid, a microgrid may be composed of smaller microgrids or “fractal units”. In such a configuration, the network becomes one of simplified power flows and communications through distributed substations.
The IBTS greenhouse is a biotectural, urban development project suited for hot arid deserts. It was part of the Egyptian strategy for the afforestation of desert lands from 2011 until spring of 2015, when geopolitical changes like the Islamic State of Iraq and the Levant – Sinai Province in Egypt forced the project to a halt. The project begun in spring 2007 as an academic study in urban development and desert greening. It was further developed by N. Berdellé and D. Voelker as a private project until 2011. Afterwards LivingDesert Group including Prof. Abdel Ghany El Gindy and Dr. Mosaad Kotb from the Central Laboratory for Agricultural Climate in Egypt, Forestry Scientist Hany El-Kateb, Agroecologist Wil van Eijsden and permaculturist Sepp Holzer was created to introduce the finished project in Egypt.
