The way in which we design, create, maintain and use urban landscapes is likely to change radically in the next 15 years (in fact, modern society is in for overwhelming change). Urbanisation, climate change and the rapid rise of technology and artificial intelligence (AI) will see to that. Don’t think that the rate of change will be the same as has occurred in the previous 15 years, for technological growth is on an exponential growth curve, not a linear one. Cities and systems are becoming smart, connected to the Internet of Things and that is just for starters. So how will this change the way we design and use our urban landscapes?
Firstly, we know that there is huge movement of populations from rural to urban life, especially in the developing worlds and most markedly in Asia. This creates huge pressure for new urban infrastructure and this is not always well planned growth, especially in terms of forward thinking to account for future changes. Nonetheless, it is happening and happening fast. The UN expects 66% of the world’s population to be urban by 2050, by which time there will be 9bn of us – so 6bn in cities. Mega-cities have to grow in a way that sustains huge numbers of people.
Secondly, climate change is also occurring at exponential rates, raising the difficulties of living in any environment but with especial problems for mega cities, most of which are in coastal regions and subject to rising sea levels and worsening weather patterns. Cities are hotter than the surrounding land due to the nature of materials used, whilst heavy rainfall brings flash-flooding. In arid countries, built environments are in danger of becoming too hot for humans to inhabit. Cities will have to take on these challenges, generating micro-climate.
Thirdly, technological change is happening exponentially and this will impact what we do, how we live, how – if – we work and how we tackle the above problems. Some view the challenges and changes with fear, thinking they will only exacerbate problems. They could do, anything can be mismanaged (such as a planet) for example. I foresee that technology is actually the only way we are going to get ourselves out of the mess we have created, the only thing that can act on the vast scale needed to re-balance an out-of-kilter Gaia.
When we take these three factors into account, we can see that the future of urban landscapes has to be so much more than the addition of the odd pocket-park here and there. Landscapes have to mitigate the environmental factors, make huge mega-cities liveable for a population increasingly disconnected from nature and provide meaningful lives in an era when many of us may not work in the way we are used to.
Weedy and neglected landscape plantings are all too common. No-one wants to pay for maintenance
How will cities become smart and use this to better the environment? If we are looking to increase the amount of urban landscaping significantly, then the first issue to tackle is cost of maintenance. No one wants to pay for maintenance and often, no one does. How many planted landscapes do you see smothered in weeds, wrecking or negating the designed purpose? Or municipal plantings and car-parks where plants inevitably die and are never replaced, leaving huge gaps. Shrubs hedge trimmed into amorphous shapes because that’s the quickest way to “maintain” them. It’s a poor standard and it’s all we’re going to get – no-one is going to pay for trained horticulturalists to do something better.
Landscape lobotomy: maintenance is the quickest, cheapest possible
Yet there is an interesting possibility – automation is likely to remove nearly 50% of jobs in the next decade, especially low-skilled or repetitive ones. In the landscape trade, there are already semi-autonomous strimmers and grass-cutters on the market, how long before we have horticultural robots maintaining our landscapes? All the technology is already here, prices are falling and an uplink to an AI would identify every weed known, give the correct procedures, know how and when to prune every plant in common cultivation. Robots would work long hours without tea breaks! If basic maintenance getters a lot cheaper, we can have more landscape and such robots would be cheaper, eventually. Living walls would be a prime candidate, with a simple maintenance cradle (much like a 3D printer head) that crosses the wall with a maintenance bot on it. I’ve seen so many potential living wall projects fall at the maintenance-cost hurdle. In such a scenario, displaced maintenance crew can retrain as bot-supervisors or true horticulturalist for private clients.
Horticultural robots will make maintenance cheaper and more effective.
We’re going to have to do more than just make maintenance affordable; rather, that is the factor that releases the possibility to do more urban landscaping. Many of the elements we need to put in place are already in existence and being used, but we need to join the dots and think holistically. For example, green roofs are seen as a separate trade from green (I prefer living) walls. Instead, we need to be talking of biological membranes (biomembranes) for buildings, a whole-system concept, where the living skin regulates the internal environment, filters pollution in both directions, dealing with generation of energy, cooling, clean air and water. Living walls that currently use potable water for irrigation when they could be cleaning up the used greywater that all buildings generate is another example.
Building Biomembranes regulate building ecology and create vertical landscapes
Systems that provide services that are of consequence to the functioning of a building, street, or neighbourhood need careful management and control, much of which will become automated. In just the last year, for example, new irrigation controllers have come on the market which not only are connected to you via internet, they also connect to the nearest weather station and adjust their regime according to the conditions. I use these for living walls; I do not advocate any irrigation for horizontal landscapes in temperate climates. But things will move beyond this, with AI monitoring ground moisture levels and moving harvested rainwater from one holding system out to another part of the city where it is needed. And urban farming – especially vertical – will be a large part of mega-city greening, although it might not be on display. Sophisticated hydroponic systems are springing up in warehouses and roof-top polytunnels all over. Such food can and should be organic, local, healthy, nutritious.
A smartly connected landscape means we can maximize the benefit it gives to the people who live, work or pass through it. With the majority of people living in urban mega cities, we have to create an environment that is fit for ultra-dense urban living. As these metropolis’ grow, people will have less and less daily contact with Nature, which is not good for our deeper wellbeing. Biophilia is our innate need for contact with the natural world: plants, trees, flowers, insects, sunlight, water, earth. A concrete jungle is not a substitute for the real thing but we mostly won’t have time to “get out there” and experience wild Nature.
I think inner city pollution will blow over – excuse the pun- in the next 5-10 years as we start a massive switch over to electric transport, most of it driverless. In fact, drone taxis are already under development and as buildings and living habitats reach skyward we can expect the landscape to move with them. It will become commonplace to have high-level dronepads – even private ones. Some people might not even go down to the ground much! So landscapes and biophilia must come to them. Fortunately, there is a rash of building-integrated vegetation going on and I see this trend increasing. Incidentally, if you wanted more good reasons for using bots to maintain planting, imagine working on living walls or trees that are 50 stories up!
As for the wider environment and the looming crisis of climate change, I can only hope that emerging nanotechnologies give us the tools to clean up our act and neutralise the positive feedback loops we are creating. Scientists are already working on nanotechnologies which capture and convert carbon into useful materials and one day such microscopic machines may roam our land and seas, removing plastics and other dangerous waste. If this is done at a molecular level, we turn problems into resources. We’ll be printing our houses (already being tested) compounds made from waste materials but without the current worries of using say, bricks made from recycled plastic which off-gas VOCs. We can only hope these technologies emerge before it’s too late to save the climate in a state that we can survive in.
So the next 10-15 years are going to see change at an unprecedented rate and it may not all be a smooth ride. I am excited by it however and think that there is much to be done to ensure that we create new urban environments worthy of habitation and that we take care of all environments and indeed the whole planet. Smart cities are coming and at their best they could loosen our imaginations and liberate us from a monotonous life of work and stress. Let’s make that the scenario that happens…

This review first appeared in Thinking Gardens in February 2016.
This book represents a new wave of thinking about “natural” planting that has been emerging in recent years; actually it has been developing for the last thirty or more years but like all new things, they tend to follow an exponential growth curve. I’d say that right now we’re near the base of the steep upward bit with this one. Left unchecked, exponential growth tends to end in collapse but this idea deserves to stay the course. To do that it has to translate from a style into a design language and that’s what this book is really about.
This is a very US-centric book, unsurprising since Thomas Rainer is from Alabama and Claudia West, though of East German origin, lives in the US. I would have liked her influence to have given the book a more European feel; it would have been richer for it and more globally relevant.
The book has already been reviewed on TG by James Golden but although I’ve read this I’m not referring to it, save for one point. Needless to say, that review is also very US-centric; my purpose is to give a more UK/European viewpoint.
The thinking in this book is very design-led, in which the authors refer to landscape archetypes, which I think is very useful. However, they only select three – grasslands, wood and shrubland and forest. Given the vastness and variety of American climate types (which has just about everything), I’m surprised they didn’t mention desert landscapes, arid-mountainous or Mediterranean (as in Californian coastal regions); I suspect they have simply not worked with these climates, yet to omit them from a listing of archetypes is limiting. It is clear too, that their interest lies mostly in the grassland or prairie archetype.
There are many archetypes other than the three mentioned in this book. Desert near Dubai, UAE.
Referring back to the JG review, he wanted to add another archetype, Edges. I would argue that the wood and shrubland archetype is an edge, or rather a transition. Only in farmer’s fields do we have an edge as such. I would think of these archetypes as parts of a sine wave, one transitioning into another as climate and topography dictate. This sine wave also rolls around the globe over time, one archetype superseding another in any given place. Remember that the Sahara desert was woodland just 10,000 years ago, when we emerged from the last ice-age. This fits with the theory that there is no such thing as an ecological climax.
Another interesting thing to come out of this book is the idea of “designed plant communities”. You could say that any grouping of plants together is a designed community but the context they use of grouping plants by habitat-type rather than just their visual look is refreshing. This makes good sense, provided that such a designed grouping is appropriate within its wider environmental context. Taken to its logical extreme, however, you end up with native plants only.
What may be harder to work out is how much of this philosophy fits into a garden. Even the largest garden can’t fit in a whole wood, let alone a prairie, so of course, we must work by inference. This aspect of things is not really discussed in the book and most of the pictures are of large gardens in amazing settings; domains of the lucky few who we landscape designers occasionally get to work for. Yet for the majority of small garden owners, instruction for the adaptation of these principles is missing.
The Lurie Garden, Millennium Park, Chicago by Piet Oudolf exemplifies modern Naturalistic planting. This is large ribbons or drifts of plants rather than the species intermingling favoured in this book
The same garden in November; form is held in the stems and shapes of the seedheads but use of some woody plants might add more winter form?
I feel that the book only really looks at one archetype, that of New Perennial/Prairie style gardens and there is a big focus on this at the moment. I might compare this book with Oudolf & Kingsburys “Planting, a New Perspective”. That book, whilst not getting down to the archetypal design level, is more European in focus, so possibly a good companion read. Yet it too, mostly deals with perennial-based planting, as you would expect from these gents. The work of Nigel Dunnett and James Hitchmough comes to mind too. The fast-changing essence of many of the plant species used means that these perennial plantings are subject to rapid change, even degradation, over time as some of the most desirable and favourite species are so short-lived (Achillea and Echinacea for example).
I think the Wood and Shrubland archetype is the most likely to resonate with those seeking to create a garden, yet the ones of great importance to me, in a European and specifically coastal Southern England context, is that of the unmentioned Mediterranean or Arid-Mountainous archetypes. Whilst some areas of the Mediterranean clearly fit the Wood & Shrubland archetype (ie broadleaf and evergreen woodlands and Maquis), others such as Garigue, Salt Marshes and Rocky Shorelines, do not. I think this range and essence adds up to its own unique archetype. Arid-Mountainous too is quite distinct (although again with areas that fall into the realm of other archetypes), yet gives us wonderful, tough plants like Perovskia. The Dutch biologist Brian Kabbes has done much to inspire and educate us with his exploration of plants in Kyrgyzstan.

To me, one of the biggest drivers in creating naturalistic planting communities has always been about resilience. To my mind, planting should survive without irrigation, so low water-use plants are attractive. I can’t think of a single garden in the UK that couldn’t survive without irrigation, the desire to use pop-up sprinklers is ridiculous and surely industry-driven. Climate is changing now beyond speeds that Nature can shift plants and ecologies around the globe, so it is something we humans must do if we want a future landscape of any description (oh, and for our own survival). So we have to transmigrate landscapes from one continent to another to keep pace; yes, with all the risks that entails when introducing new species (and it would not be just plants we’d have to relocate). So learning about plant communities and how to build them is a vital skill which this book begins to explore, yet could have gone much further in instructing us on.
This coastal garden I designed in Southern UK loosely mimics the Mediterranean archetype, and uses a full range of grasses, perennials, sub-shrubs, herbs, shrubs and trees.
In the European context then, archetypes other than grassland/prairie might be more useful and translatable into a garden context. That this book has not covered these is not really surprising but it is a mistake to think that the new language of resilient/natural/sustainable landscapes is dominated by perennials and grasses. This aspect is possibly a trend within the underlying drive for a natural interpretation.
A European version of this book is needed, which could perhaps take it to the next level of design language development. In this respect, inspiration can be drawn from another book, “A Pattern Language” by Christopher Alexander, which although about architecture and space, is also about soul, spirit, context and community, realised through the use of a language of patterns. In a very real way, “Planting in a Post-Wild World” attempts to create an archetype-based design language and is a valuable contribution to that. We just need the language to be global, or to see this book as a regionalised attempt to cross boundaries and develop new thinking.
This is an important book and I recommend it; for all its limitations it shows the way to develop landscapes that are truly new and profound.

In my previous post I talked about a regenerative planting methodology for urban landscapes, in which I suggested you would manage, rather than maintain your planting areas. So how exactly do you you do this? Both involve work and the difference is a subtle but important one, in both attitude and application. Think urban forester rather than garden pruner. The picture above illustrates this perfectly, so let me explain.
It shows two hazels in my garden, both planted as young bare-root trees in the winter of 07/08. The one on the left was coppiced down to the ground in the winter of 12/13, the other has been pruned to keep a structure of older wood, with all suckering growth removed annually. What is the difference? The coppiced hazel has been less work overall and has not been touched since it was coppiced, the pruned tree has been pruned annually, which was not great amount of work but this is just one tree. If there were a hundred, it would be a different matter. The main difference is that the pruned tree has catkins, the coppiced tree does not, but I think this is a difference of genetics, rather than pruning technique, as they have always been like that. The shape of the pruned tree is also wider in its spread and will become gnarled as it gets older.
So in terms of management, if you go the coppice route you do nothing much to the trees except coppice them every 4-5 years. I would suggest that 50% of the trees are coppiced so that not all structure is removed at once. Notice that the growth of the coppiced hazel is straighter, making for a productive yield of canes and poles that can be used in the local community. Other trees that can be coppiced include sweet chestnut, lime, alder, ash, willow and hornbeam. Birch and oak will coppice, but from young trees only. Willows and dogwoods grown as bushes for their winter colour can be coppiced or “copparded” (inbetween coppice and pollard) to around 300-600mm every two years to keep the winter stem colours strong.

By adopting such techniques in our larger masses of urban street planting and parks, we would deliver a more biodiverse, beautiful and biophilic interaction for all concerned. It would also cost less both to establish and possibly to maintain, than traditional planting. The above willow is beautiful and graceful, yet I have seen it all too often used in municipal car-parks and reduced to a-n-other shrub that is caressed all to frequently with the indifference of a hedgetrimmer.
Time to re-wild our inner selves, and our urban landscapes. We can do so much better than the average landscape we see in our towns and cities.

Almost all urban landscapes are contrived and designed, due to their artificial nature and short timescales of development and use. We see increasing use of mature rootballed trees and extensive hard landscape and this is normal for intense inner urban areas; I do get concerned that the increasing complexity of urban planting systems divorce trees particularly from their natural functions and prevent the occurrence of the biological interactions/communities that go to make up an ecosystem. For example, I have seen trees planted whose surface levels are around a metre below the surrounding paving level. No matter how well designed, this seems fundamentally wrong to me.
So I’m thinking that there must be a way of dealing with the majority of less intense landscape zones (especially where there isn’t the financial budget that a high-end development attracts) to provide urban regeneration, ecological restoration and biophilic connection, all on a modest budget. This would create a new method to allow for wide-spread adoption in urban and suburban zones. I think the solution comes from Nature’s own process of natural regeneration and a developed philosophy of minimal (but specific) preparation.
silver birch are pioneering species for natural regeneration
Starting from the observation that Nature is very efficient at regenerating itself, what can we do? Too often, I have seen unnecessary interference in this process. I still recall that a few years after the great storm of 1987, I walked through some nearby National Trust woodland of pines and birch. A great deal of damage had been done with many trees blown over. Birch had however, regrown abundantly from dormant seed and was already three or four foot tall. The NT then sent in the bulldozers to clear out the fallen wood so the area could be – replanted. I watched them tracking over all the natural regeneration. Why didn’t they just leave well alone? The restoration of the woodland was only slowed down by such clumsy interference and this was not even a productive forest.
If we simply broke up paving in our urban centres and loosened up the sub-base, what would happen? Nature would soon find a footing and things would start to grow; however, that process would be too slow and unpredictable for human sensibilities. So what if we did a little more, adding a small amount of topsoil to the rubble, planting small (1+1 year transplants) bare root trees and shrubs, with plugs of understory forbs, ferns and grasses. Starting so young, we’d generate a successful community in no time. These could be designed as narrow ribbons – two to four metres wide, inserted into suitable wider areas of paving.
An urban area suitable for natural regeneration
The above area was one I thought would be suitable for such an approach; there are many such areas throughout all urban spaces. They cry out for regeneration, yet seldom can this be done for lack of adequate finance. Below is a quick sketch showing how it might look.
Sketch showing regenerative planting
The benefits of such an approach would be huge. It would cost far less than using a traditional approach to landscaping such an area, maybe half (I haven’t costed it!). The care would move from maintenance to management, using a rotational coppice methodology, rather than trim and tidy (which always ruins a plants natural habit. Biodiversity would be hugely enhanced, air pollution mitigation would increase, wind buffering, urban heat island reduction, stormwater runoff (they would act as rain gardens) and of course, our biophilic needs, our connection to nature.
Someone needs to be bold and try it; talk to me…

I’ve written before on the subject of adaptive landscapes and trans-migrational landscapes but I’ve been reading recently of a real-life ecology that was created by man in the last 200 years, and is thriving. This is on Ascension Island in the South Atlantic Ocean, a once barren volcanic rock, which is now a thriving cloud forest, created in a somewhat uncoordinated way by successive generations of British sailors and governors bringing plants from all over the world. Where there were once just 25 species, there are now over 200, as this article tells.

Whilst this example may be a one-off, it is nonetheless a hopeful sign. If new and thriving ecologies can be created with little real thought and science, it gives hope for what we can do if we put our minds to it.
In my previous articles mentioned above, I outlined the reasons why this is necessary. To recap, it is due to the planetary changes that are now occurring, whose effects we have yet to fully experience, which is going to change this planet for millennia to come, even if we get a grip on carbon emissions, which we must of course do. If we don’t, runaway climate change could make this planet largely uninhabitable (at least to higher life forms). Ecologist have to radically re-think what they consider to be ecology, for Nature cannot adapt the landscape at the rate of our man-induced changes. That means that species cannot adapt and move with the shifting geological region of the climate zone they are used to. Zones are moving North and South, away from the equator at a rate which may change 20% of the world’s climate zones by the end of the century.
Of course, Nature will correct things given time, but mankind cannot afford to wait, if it wants a planet worth living on – and the ability to live on it. That’s why the Ascension Island story is such good news. I would dare bet that we could extensively re-vegetate (or terraform, to use a word found in science fiction stories) areas within a 50 year period if we turned our minds to it, and our political will.
Ironically, I can see some of the stiffest opposition to this coming from conservationists. Much is made of the negative effects of the global migration of plants and insects, but we have to balance that with the positive gains, which are seldom mentioned, yet so taken for granted. And the planet is going to change now, whether we want it to or not. I’d rather the UK (for example) had a Mediterranean flora and fauna than none at all. We may one day grieve the loss of our native oaks, finally unable to cope with the higher temperatures, but we would surely welcome the holm oak (already naturalising in the South coast area), cork oak and olive here. Having an ecology of beauty and abundance is what counts now, not preserving what we are used to having. Get used to that; it’s already too late.
But new adaptive ecologies, created by transferring plants, insects and microbes from other similar zones in the world, would give us a new practice, that of trans-migrating landscapes, and a new science, a new understanding. In this we must learn not to manipulate, but to understand Nature, to assist in what she would herself do, but over millennea. And we must do it within a lifetime.
Best get started…

With the climate shifting now so rapidly that we cannot foresee what the future may bring – or rather, with an ever increasing certainty of life as we know it struggling to survive – do we need a new approach to our understanding and management of our natural landscapes? I think this will become inevitable and that this idea needs to become a proactive rather than reactive measure.
A quick look around the globe shows Arctic ice melting at unprecedented rates, massive flooding events (in Bangladesh recently 20m people were displaced), increased hurricanes (h. Sandy), both in frequency and strength, desertification through deforestation and inappropriate agriculture and relentlessly increasing global temperatures, to name just a few that come to mind. And we can see effects much closer to home. The UK is likely to lose most or all of its ash trees due to the fungus Chalara fraxinea, which has mutated and migrated from Japan, where it is a balanced part of its ecosystem. Ash trees make up 40% of the UK landscape canopy. This follow from our lose of elms, but oaks have their problems too, as do horse chestnut and and larch, which although not native, are under attack from imported diseases. We have everywhere, a landscape under stress, that cannot adapt to the rapidly changing environments we humans have imposed upon the planet, either from our living patterns or from pollution. Our landscapes are under duress as never before. Vast and rapid change is inevitable and cannot now be stopped. But there is possibly something we can do, and that is learn to help speed up Nature’s adaptations. This would involve actively changing the flora and fauna of our native landscapes, an approach that would not be without risk, but might mean that some kind of meaningful ecology can adapt and survive.
It is clear that to do nothing is to watch our beloved regional and continental. landscapes change beyond recognition. But this would require a sea-change in thinking and current practices. Ecologists naturally resist the introduction of new species, with good cause; the aforementioned tree diseases are with us at least partly because of imported plants or timber. Lists of invasive species and control advice is provided in the UK by the Non native Species Secretariat; but I now think that we are beyond preventing the influx of invasive species and that we must look ahead and ask ourselves: do we want an ecology and landscape in 50 or 100 years time? Of course the answer is yes; we depend on our landscape, body and soul, and we may regret that we were forgetful of that for so long. But we cannot preserve what was, into the future.
My previous post was a review of a book by Bill McKibben, a leading environmental thinker, who says that we now live on a different planet, that it’s future will never be as its past was; he renames the planet Eaarth. We have caused this; if we are to adapt to our future, we have to re-think our attitudes and expectations. We cannot conserve England’s green and pleasant land; it is gone, or going. We must adapt it to suit its future, to build new ecologies, with new species or variants of existing species that are better able to cope. Ironically, trans-migrating species from one continent to another may save them from extinction in their original habitat.
This would be a big challenge; it is easy to introduce a new tree species, but it is the microflora and fauna that come with them that is important, for both the good and the bad. Sycamores are a now familiar part of the British landscape but are non-native and considered invasive. Whilst they are robust and may be well suited to our warmer climate, they are ecologically barren in the UK landscape, when compared to our oaks, which support some 300 + species of life. And this is the crucial bit; nature builds up complex and diverse ecosystems, of which we are still largely ignorant. Thus if we are to be able to do this with any success, we need to learn a new discipline, that of building micro and macro ecologies to suit our new future. If we put the same energy into this as we do GM research, it would be far more productive and useful – but it can’t be funded by private companies; this is our future, not a potential for financial gain.
And whilst we are at it, let’s build a new agriculture, based on perennial crops and trees, all as part of our ecological future. A diverse polyculture of trees, shrubs and herbs which provide a diversity of food, fuel and resources, including wildlife. Such an agriculture (or agroforestry, forest gardens, permaculture) will not be dependant upon fossil fuels, chemical fertilisers or pesticides as it’s perennial; harvesting can be done by hand or machine, and methane from cellulose digestion can provide the fuel for tractors where they are used. Nuts replace wheat and we move to a far more resilient and varied diet, which will make us healthier and give us food security, both of which are in rapid decline. Such annual crops as we do grow will be the domain more of the market-garden, a philosophy which we must revive to give us local food. Who knows, such balanced, wholesome and resilient landscapes might even be good for our soul’s too; certainly peace of mind relies on having a secure life, and we are rapidly losing that, far more than we realise.
So we need to build a new philosophy and practice of trans-migrating landscapes from areas of stress to areas of comfort, to match the shifting of climates zones around the world. It’s quite a challenge but we might just learn some humility and a far deeper appreciation of nature. In fact, we might just finally discover that we are inseparable…
