Iberia Study – Xeriscaping and Permaculture

News, , , , , , , , , , , , , , , , , , , , , , , , , ,


The term “xeriscaping” defines the process of designing landscapes for water-efficiency. The term was first coined in Colorado in 1981, but has existed throughout cultures for many centuries. Xeriscaping is achieved through the practice of designing with 6 basic principles:

  • Minimization of high water demanding ground covers, i.e. lawn areas (using turf only when it provides function)
  • Efficient irrigation techniques
  • Protection and improvement of planting soils
  • Suitable plant species selection for the specific environment (natives and naturalized species)
  • Continual maintenance to reduce water requirements over time

Although the term was first used here, the concept has been implemented throughout the world. Historically Iberians, (i.e. modern day Spain and Portugal) before modern irrigation techniques were very innovative in this field, cultivated fame for their agricultural innovations in dry climates. (As a nifty side fact, this agricultural skill set is the reason the small nation of Bermuda has such vibrant Portuguese subculture today, as they immigrated thousands of Portuguese farmers during the American revolution because they feared an American embargo and needed help becoming agricultural self sufficient.)

Upon arriving in these countries it is clear that there is an embracement of the demands of the environment. There is an acceptance of the existing climate and an adaptation to the natural environment is made rather than fighting the elements at high expense. From this acceptance arises a unique aesthetic that we here can learn from as we move towards sustainable design as a country. A way of rethinking not just our landscape choices but our use of art, hardscape and architecture to match the existing environment rather than battling the natural setting.




Permaculture, as it applies to the landscape, is an attempt to mimic symbiotic relationships found in nature in the practice of agriculture, in order to create self-sufficiency and sustainability. America remains one of the highest consumers of energy, largest producers of waste, and most excessive consumers of artificial fertilizers.

In Iberia, as the colonial empires fell apart, the Spanish, and more extremely the Portuguese, became very poor. Much as many countries that have gone through financial hardships, land became abandoned throughout the major cities, currencies fell apart, and families began to need a means to lower expenses. Through this combination of events, these cultures reverted to the historic practice of self sufficiency in micro farms. All throughout these cities today you will find brilliant little farms using found materials to grow crops in abandoned lots. Because these are personal farms, unlike American mega farms, they lack major irrigation, industrial fertilizers, and monoculture production. Instead, they mix crops and use the symbiotic relationships of the plants to sustain each other, have crop productions all season long, and keep water requirements lower.

In the United States, this has already become a major planning innovation in Detroit as it begins to recover from economic hardship. Entire city blocks have begun to transform into functioning urban farms. Even in areas that may not have the economic hardships, we can still see the value in the environmental sustainability these practices hold.

By reducing the need to transport crops over great distances we can reduce the environmental destruction of the energy usage, but it is more than that. When designed with aesthetic intention, we can turn what would be a landscape that just consumes time, money and water into beautiful, consumable resources that actually save you the owner money at the grocery store.

Scandinavia Study – Cold Hardy Vegetation and Contemporary Minimalism

Invasives and Natives

We as landscape designers look to enhance the local outdoor setting through the use of natural materials. Often times there are many native species and materials that can accomplish the aesthetic we are searching for. When designing for the quintessential Colorado architectural styles of American Bungalow or Mountain Rustic, the use of natives to match can be ideal. Local stones and local species can round off the great Colorado archetypes that we are chasing. Many times in the era we live in though, architectural styles are imported. In these circumstances, the landscape pallet of locals might not be the complete pallet desired. In such circumstances it is important to consider import choices carefully.

Historically, very little attention was paid to invasive species. To date, across the western world, we are battling the mistakes of the past. Because of the lack of attention when importing horticulture, we now have pests such as the nightmarish fire ants, the emerald ash borer that devastates out forests, and the Asian tiger mosquito that many of us know well. Many times however, it is the plants themselves and the weeds hitchhiking in the soil that can be the most destructive to the ecosystem. One of the best examples of this is the Kudzu vine. A vine introduced in the late 1800s, Kudzu was hailed as a great planting solution for erosion control. Now having made its way into the wild, the vine can grow up to a foot a day, completely overtaking even entire trees and shading them to death. Now kudzu, like many other species, are a constant battle wreaking havoc across the continent.

With that said, there is nothing inherently evil about the use of foreign vegetation in the landscape. It is only when the species used have the capacity to spread into the wild, and out-compete the native vegetation, that it becomes an issue. So, how do we as landscape architects in a challenging horticulture climate like Colorado, with limited off season color in the native pallet, responsibly preserve the ecosystem while creating beautiful outdoor spaces? For that, we have a number of considerations.

  • One option is to simply use foreign species that will not survive our winters as highlights within the landscape for seasonal “pop”. In this circumstance we preserve the ecosystem by using annuals that don’t have the capacity to become invasive.
  • A second option is the use of sterile cultivated hybrids and single gendered plants so that the species do not have the capacity to reproduce and spread into the wild. In this way we can scour foreign locations for incredible plant species and use them without ill effects.
  • Another consideration is the use of regional plants from close climates cultivated locally. Over time these species from nearby can acclimate and begin to withstand our winters. In this way we are simply expanding the range of semi native species and pushing the envelope of their domain slightly. An acceleration of a natural evolution if you will.
  • Lastly, we can consider the use of species that can survive in the urban environment, where we enhance the native soils and irrigate, but would be unable to survive outside of that micro-ecosystem. With the use of sustainable systems such as rain water collection and home composting, there can be no real environmentally damaging effects.

With all this in mind, in the end, it is important to remember our role as environmental stewards. When the opportunity to propagate endangered local species back into the environment presents itself, we should take it. Natives aren’t to be forgotten or ignored as they often have become in recent years, but that doesn’t mean that a landscape that that uses foreign species as highlights is necessarily failing in our role in creating a sustainable future.




In design, we don’t always have to reinvent the wheel. There is a big world of ideas out there to learn and develop off of. Colorado may not have a great history of landscape architecture but there are areas of the world with similar environments that do, and we can learn from them. One of those, for us here, is Scandinavia. (i.e. Norway, Sweden, Finland and Denmark.) Humanity has been practicing landscape design for many centuries in these countries. The way they design for the harshness of winter, to avoid bare bleak landscapes is inspiring. They design for it, instead of suffering through it.

As contemporary architecture progressively takes its foothold here too, we can again look to our Scandinavian friends for inspiration. As major arbiters of this post modern era of architecture, they push the envelope of landscape design as well. How do you extend the contemporary aesthetic from the structures themselves into the spaces between? There are few cultures more progressive than the Scandinavians in this regard.

At the end of the day though, the best teacher of landscape design is nature itself. To go into the natural environment and recreate the juxtapositions and symbiosis there, produces some of the best results. Few places on earth will take your breath away like the fjords and archipelagos of sparsely inhabited and untainted far northern Europe. A reminder of how nature looked before people and what we can do to bring it back.

Central Europe Study – Sustainable Communities, Recycling, & Reclamation

News, , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,

Post World Wars Central Europe might not have a lot a lot of positives you can say were taken away from the devastation of war. However, when everything is bombed to rubble you certainly have a clean slate to start over from when it comes to design. Many cities like Frankfurt, Bonn, and Berlin that suffered the highest amount of city destruction took the opportunity to rise from the literal ashes with a new era of urban design and architecture.

               In Frankfurt, for instance, over 50% of the infrastructure was destroyed by 1945. Today, 52 percent of the city area is green space, consisting of parks, woodland, farmland, orchard meadows, grassland, allotments and hobby gardens, cemeteries, roadside grass verges and bodies of water. And as of 2019, Frankfurt has been ranked the most sustainable in the world.

               Sustainable communities can arise naturally over time as well, through the reclamation and re-purposing of infrastructure. When a large industrial site or landfill, that used to be on the outskirts of town, finds itself decommissioned and eventually absorbed into the growing city, it can present a multitude of challenges (i.e. contaminated soils, eye sores, wasted space, etc). Europe’s ancient cities can serve as great examples of how to cope and even benefit from these challenges.

               For industrial sites, Landschaftspark in Duisburg, Germany is a patent example of how a derelict site can be reclaimed without disturbing the polluted soils through deconstruction and wasting materials and energy in mass deconstruction. Through this they achieve the addition benefit of preserving a bit of history. Landschaftspark was transformed from a disused old industrial ironworks into facilities with multiple uses into a one of a kind park space. The huge buildings of the former ironworks have been modified to provide patrons with a multitude of new functions such as alpine climbing gardens created in ore storage bunkers and a viewing tower made from a decommissioned blast furnace.  Landschaftspark represents how an area can celebrate its industrial past by integrating vegetation and industry, promoting sustainable development and maintaining the spirit of the site without morning it as an eyesore.

Metabolon in Bickenbach, Germany serves as an interesting example of landfill reuse. Metabolon is a multi-purpose site built upon a decommissioned landfill. The site today takes advantage of the artificial topography to serve as serves as a lookout point, bike track, public park, playground, and research center and more. Converting waste to energy is the most significant goal in the research center. What was a disaster for the town has become an attraction and public benefit.

The benefits of recycling and reclaiming are shared among citizens, tourists, developers, customers, and the environment alike. Firstly, an industrial reclamation project produces ecological benefits to the environment and its inhabitants through the growth of plant materials that harbor ecology that break down pollutants in the soils and filter water runoff. Secondly, by transforming dilapidated space into functional and aesthetic pieces, a city brings economic revitalization to the surrounding area. And thirdly, when site is transformed into a useful and attractive space the area becomes more attractive to potential businesses and tourists.

This mindset of design applies to projects large and small. When we think about renovating our residential spaces we have two options. Tear everything out and start anew, or integrate and recycle. Many people in the industry will take the easy road- remove it all and put in new. I urge more of you to consider the value in preserving and recycling the old. Keep more structures out of the landfill. Integrate those priceless 30 year old shrubs into the plans if you can with a nice pruning. Reuse materials where you can. New is not always better, it’s just cleaner for a few years.
