Introduction
In the realms of sustainable land management, farming, and permaculture design, many terms circulate that refer to the process of analyzing a piece of land to understand its unique attributes and potential.
"Land Evaluation", "Land Assessment", "Site Assessment", "Site Survey", and "Site Audit" are among the phrases you may encounter. For the purposes of this post, we will be using "Permaculture Site Analysis".
The Purpose of Permaculture Site Analysis
Permaculture site analysis is a methodical approach to understanding a property's unique qualities and potential. The goal is to glean detailed knowledge of the land's physical, biological, and invisible attributes, which will inform the design and management strategies aimed at fostering sustainable land use and resource management.
In essence, permaculture site analysis enables us to work with the land rather than against it. By identifying the strengths, weaknesses, opportunities, and constraints of the site, we can align our actions with the patterns and resilient features of natural ecosystems, resulting in landscapes that are productive, regenerative, and in harmony with nature.
The process of permaculture site analysis involves a series of steps to thoroughly understand and document the unique features and conditions of a given piece of land. It allows us to observe and interact, drawing from one of the core principles of permaculture.
Property Description
GPS Coordinates: Knowing your site's exact global positioning can significantly aid in planning and implementing various aspects of your permaculture design. GPS coordinates will provide you with a precise location, enabling accurate sun and shade mapping, topography analysis, and even climate prediction.
Location and Wider Area: A comprehensive understanding of your property’s surrounding environment is vital. This includes details like proximity to nearby towns or facilities, accessibility, and the characteristics of the wider ecosystem. This information can influence design decisions, as your site is part of a larger ecological and social system.
History of Land Use: Understanding the land's past usage gives clues to present conditions and can guide future plans. It reveals previous cultivation techniques, potential soil health or contamination issues, existing biodiversity, and the land's cultural significance.
Size and Elevation: The size of your plot determines the scope of your permaculture project, while the elevation has an impact on microclimate, water flow, and potential for certain types of agriculture or infrastructure. These aspects influence design choices regarding crop selection, earthworks, water harvesting, and more.
Climate Analysis
Classification: Climate is a key determinant in what you can grow and how you can grow it. Understand your site's specific climate classification (such as tropical, arid, temperate) to inform planting strategies, water management, and infrastructure design.
Hardiness Zone: Knowing your hardiness zone, a standard by which gardeners and growers can determine which plants are most likely to thrive at a location, is fundamental. It influences plant selection, planting times, and potential yield.
Averages and Extremes: Examining the average high and low temperatures, as well as the maximum and minimum recorded, can help you prepare for extremes. Understanding seasonal rainfall, humidity, wind speed, and direction patterns also plays a crucial role in the design of your site, affecting decisions from crop selection to erosion control.
Sun Analysis
The Solar Path - Azimuth and Altitude: Understanding the Sun's movement, including its azimuth (horizontal angle) and altitude (vertical angle), is crucial to maximize the use of sunlight in your site. This knowledge can inform the positioning of various elements, from plants to buildings, to optimize light exposure or shade as needed.
Timings of Sunrise and Sunset during Solstices and Equinoxes: Knowing the precise timings of sunrise and sunset during solstices and equinoxes gives you an understanding of day length throughout the year. This can affect many aspects of planning, such as when to plant certain crops or how to design buildings for natural lighting and heating.

Water Resources Analysis
Catchment and Drainage Network: Identifying the catchment area and understanding the drainage network is pivotal to managing water resources on your site. This analysis will help you discover where water comes from and how it moves across the landscape, aiding in effective water harvesting and usage.
Watershed Identification: Recognizing the boundaries of the watershed your site belongs to allows you to grasp the broader context of your water resources. It influences how you can sustainably utilize and contribute to the overall health of the watershed, which is crucial for maintaining biodiversity and ecological resilience.

Landscape Analysis
Topography and Hillshade: Evaluating your site's topography and hillshade patterns is fundamental to understanding its physical features and microclimates. These factors influence your land's solar exposure, water movement, and areas of possible erosion or landslides.
Elevation and Contour Map: Creating a contour map of your property helps you visualize its elevation changes. It's a critical tool for designing terraces, swales, or ponds, and for strategic plant placement based on varying altitude conditions.
Slope Direction (Aspect) and Angle: The slope direction, or aspect, and angle of your land play key roles in sun exposure, soil moisture, wind patterns, and temperature variations. Understanding these can guide your decisions for plant species selection, building design, and water management.
Soil Analysis
Soil Maps: Soil maps provide an overview of your site's soil types, patterns, and properties such as texture, depth, drainage, and fertility. These maps, often available through local agricultural offices or online resources, can give initial insights into your soil's suitability for different crops and land uses.
Soil Testing: For a detailed understanding of your soil's health and composition, soil testing is recommended. These tests offer specific data on nutrient levels, pH balance, organic matter content, and potential contaminants. This information is invaluable in making informed decisions about soil management.
Renewable Energy Potential Analysis
Solar: Solar energy potential is an important consideration in permaculture design, influencing everything from crop selection to building layout. By analyzing factors such as the sun's path, shading, and local solar irradiation data, we can estimate the potential for solar power generation and passive solar heating on the site.
Wind: Wind energy potential is determined by assessing local wind speeds, direction, and frequency. Areas with consistent and high-speed winds are excellent candidates for wind turbine installations. Understanding wind patterns can also inform the placement of windbreaks and the design of aerodynamic structures on the site.
Other Considerations
Wildlife: The presence of local wildlife can both enrich and challenge a permaculture system. A thorough site analysis includes identifying local fauna, their habitats, and patterns of movement. This information informs design decisions that either encourage or deter wildlife interaction.
Air & Noise Pollution: Understanding potential sources of air and noise pollution is crucial. Proximity to roads, industries, or farms using chemical sprays can significantly impact the air quality. Noise pollution sources may impact the tranquility of your site and may need to be considered in your design.
Fire Hazard: Evaluating fire risks involves understanding local fire history, vegetation types, wind patterns, and proximity to fire-prone areas. This information guides fire-prevention strategies in the site design.
Security: A permaculture site analysis also includes assessing the site's security needs. Factors to consider include access points, visibility from public areas, and local crime rates.
View: Visual considerations play an important role in creating a harmonious and enjoyable space. Identify key viewpoints on your site and consider how they can be preserved or enhanced. Conversely, undesirable views can be minimized with careful planning and planting.
Invisible Structures
Title and Ownership: Knowing the legal boundaries and understanding who holds the title to the land is the first step in any site analysis. This includes understanding any shared ownership, lease agreements, or access rights that might affect the land's use.
Stakeholders: Identifying all stakeholders is essential. Stakeholders can include anyone with an interest in the land, such as neighbors, local community groups, native titleholders, or government bodies. Understanding their interests and potential impacts on the project is vital.
Zoning and Restrictions: Each piece of land will have zoning laws and restrictions attached to it, determined by local and national legislation. This could include restrictions on certain types of land use, building codes, livestock restrictions, or protected areas.
Rights: Along with restrictions, there may be rights associated with the land. These could include water rights, mineral rights, or grazing rights. These rights may be held by the landowner or third parties.
Taxes: Understanding the tax implications associated with the land use can help plan the financial aspects of the project. This could include property taxes, income taxes from produce sales, or tax incentives for sustainable land practices.
Permaculture Site Analysis is not just a process, but a comprehensive journey towards understanding your land. The steps highlighted in this guide are essential in assisting you to comprehend the potential of your land and the unique challenges it might pose.
