The word Permaculture means permanent agriculture that presents up-to-date aboriginal ecological knowledge for the creation of a consciously-designed, integrated, self-sufficient system that intend to increase biodiversity, reduce energy requirements and to recycle resources within the system. Permaculture principles are based on ethics, equitable interaction with environment and system design principles that offers an unequivocal vision and strategy for valid sustainable management (Mogen, 2006; King, 2008). These principles are grounded on the study of natural systems and provide source for continuous evaluation and creation of the unequivocal solutions essential to modification away from the unsatisfactory execution of sustainable management to a balanced interaction of human and environment.
The Permaculture focuses on small scale management that promote sharing, escort by a lack of concern with market recognized forest certification. The key objectives of Permaculture are environmental flexibility and vital rehabilitation which makes it suitable for over-exploited, marginal and degraded soils and water areas. A fully functioning and well planned Permaculture design is suitable to area where, as an effect of over population, family bear a large number of dependents, making time and energy for household fuel, fodder and food production is a vital consideration (Akhtar et al., 2015; Akhtar et al., 2016). These principal features differentiate Permaculture from other management systems.
2.1. Principles of Permaculture
Basically; the Permaculture promotes the concept of sustainability through the conceptualization of balancing human interaction with each other and nature. The ethical origin of the theory is “care for people”, “care for the Earth” and “redistributes assets excess to one’s own requirements” (Mollison, 2002). The fundamentals of permaculture are the ethics that are placed at centre which guide the implementation of the design principles, confirming that they are used in proper ways. These principles are universal thinking tools and can easily be utilized to ingeniously re-design our environment, society and economy in a world of less energy and meagre resources.The strategies used to apply these principles differ extensively reliant on the social, economic and ecological site conditions and available resources. The principles of Permaculture are divided into three categories:
2.1.1. Energy and Living Principles
The sustainability debate has shown a deep confusion about the procedures and structures which maintain social, economic and ecological systems. The lack of eco-centered strategies to integrate earlier ignored environmental "givens" into strategies developed by economists and decision-makers is painfully obvious. There is no simple answer to the multifaceted question of costs, economic benefits, and sustainable development. Conversely, there is a natural currency that can be utilize to measure our interdependence on environment and assist to make sustainable strategies about existing and future action-That currency is energy. The Energy and Living principles are further divided into eight principles:
- Energy Input
- Energy Cycling
- Energy Efficiency
- Intensification ion
- Diversity
- Succession and Evolution
- Use Biological and Renewable Resources
- Edge Effect
The principles of energy and living emphasize on observation of natural cycles to determine energy flows and process to lesser the establishment and maintenance inputs. Cautious and extended observation earlier to action can reduce on-going energy inputs and the systems that develop should sustain and take least maintenance. Key energy source within permaculture systems is the sun. It produces wind, precipitation and biomass. By developing systems that collect incoming energy (sun, wind, rain, manure etc.) at peak abundance before they degraded and lost to entropy, can be utilized in times of need. In permaculture systems efficient energy design is developed through zone, sector, appropriate placement of elements and structure. Most creatively and originality comes from the edges of society (Identify, create and utilize edges) that consumed by the masses.
2.1.2. Functional Design Principles
Functional Design Principles leads to Stability and Resilience by integrating functional diversity and biological fertility through mimicking natural eco-systems. These principles focus on establishing efficient relationship between components of relative location and their proper placement in a system so that it performs as many functions as possible. Valuable connections between various components create a sustainable and diverse ecosystem, not the number of elements. Diverse and productive systems act resilient in the time of need. The four sub principles of Functional Design Principles are:
- Support
- Multi-functionality
- Relative Location
- Stability
2.1.3. Attitudinal Principles
Attitudinal Principles’ are people-focused and deal with our attitudes: How people look a ‘problem’ or a ‘valuable resource’, depends on their attitude. Usually, individuals perceive a disadvantage as a ‘problem’ and then implement an energy-intensive solution to attempt to fix the problem. The Permaculturist has a different attitude that look at everything as a positive resource, and figure out how to make use of it- for example- can turn these disadvantages into useful resources through knowledge of system and elements of nature. It doesn’t matter how well policy makers can develop the site design/policies and how efficiently it all works, there are always ways to improve and add to the system. The number of ways that resources can be utilized in a system is limited purely by the information of the policy makers. The only limit to the number of uses of a resource within a system is limited to the information and imagination of the designer. The four sub principles of Attitudinal Principles are:
- Mistakes are Tools for Learning
- Get a Yield
- Turn Problems into Solutions
- The Biggest Limit to abundance is Creativity
