Native planting verses ecological planting the differences and the implications for ecological and sustainable landscape design.

7/17/2018

1 Comment

 
Many ecological landscape schemes today have an emphasis on either ecological or native planting. Sometimes confusion between the two or an acceptance they are one in the same. There is a logic behind this difference and reasons you would utilise one, the other or both in a sustainable landscape design.

Picture

Native plants are always a good choice in large regional landscape master plans. Knowing a species will establish with relative ease without the need for artificial installations is a better option. This enables them to establish faster and thrive. Native trees and plants need less irrigation, weeding and protection from the environment being more adapted to local conditions.
​
In recent times a greater ecological awareness has realised a more regional, localised element to using native species. We have come to realise there is regional variation within species. Eastern European common Limes flower 2-3 weeks later than British strains due to colder winters. This greater understanding of the particulars of local natives has added a new element to native species. This has meant some wildflower seed mixes state regional origins and local suitability. Rail companies such as London Underground when seeding banks use a specific meadow mix for the South East of England on clay soil.
​

The specific nature of native species has raised some interesting questions about ecological succession and species diversity in sustainable landscape planting schemes. In nature plant species adjust to new climatic conditions and diseases. Succession and alien colonisation is a natural process so at what point do we relax local selection of planting stock?
​
Although it has been recognised that some wildlife rely on the predictability of flowering times of native plants wildlife benefits more so from diversity within a planting scheme. A study of wildlife species densities found that there was more wildlife diversity per square metre in urban gardens than most rural nature reserves. The reason for this is there is simply a greater diversity of plant species in urban gardens than the wild. A diverse array of native and non native plants with varying nectar sources at  varying times of the year allow more diverse wildlife species to thrive in urban gardens.

Picture

One of the most popular shrubs for attracting butterflies and can be seen in nature reserves across the country, Buddleia is not from Britain at all but South East China. Some non native landscape plants such as Mahonia are a very welcome source of nectar in the depths of winter. In response to this ‘ecological planting’ is the term used to describe plantings which benefit ecology in ways such as shelter providing food or diversity in ecological landscape designs.

Picture
With the specific benefits and requirements for both native and ecological planting within sustainable landscaping it should be up to the designer to research the local environment. This will enable precise execution of ecological landscaping principles within the clients brief.  

Research of local geology, hydrology, history and ecology will give the sustainable landscaper the planting palette best for local species. Whether ecological or native, the planting should be able to provide food, shelter and be self sustaining within the landscape design.

How wetland plants can clean human waste water in Sustainable, Ecological landscaping

3/16/2018

0 Comments

 
Picture
Water discharge from human habitation takes many forms. Sewage, storm water and grey water all have the potential to cause many problems to the environment around our towns and cities. The high nitrogen composition of sewage means it has the potential to cause eutrophication to in rivers and natural watercourses destroying aquatic organisms.  Grey water containing detergents and food particles also cause problems if allowed to flow freely into the ecosystem many studies have been done on the potential harm of chemical residues within grey water release into watercourses. Excess urban storm water runoff is an added catalyst to pollutants from our roads and urban environments. Dog faeces, chemical spills, paint and herbicides are all but a few of toxins that enter the hydraulic system after rainfall.

Picture

An amazing upside to this problem is that natural wetland plants have the ability to clean all waste water through natural biological processes. With a combination of sustainable landscaping installations such as bio swales, retention basins, wildlife ponds and reed bed filtration catchments. These sustainable urban drainage solutions represent and ecological way to deal with waste water from our homes and can be implemented on both a regional and domestic level.

Picture


The general conceptual layout of biological water treatment with ecological landscaping is capturing water discharge in manmade wetland zones to be cleaned before returning to the local water system.  There are multiple ways this can be achieved with swales leading to marsh areas and shallow gravel beds and a series of connected retention ponds capturing and cleaning particles on their journey through the system. These systems require no maintenance no electricity and cost on average one third of what more traditional waste management systems cost.

 A typical reed bed filtration system can filter both grey water and sewage from nearby homes. In the case of sewage ecological landscape design should be implemented to reduce odours via prevailing wind and installing a more submerged filtration bed. The main component structure of the reed bed is an excavated cell or basin of gravels with a gravitational route through dense wetland plants and reeds. The gravels and sands allow particles within the water move freely through the roots and shallow courses of the wetland.


Picture
 
The roots of the reeds oxygenate the water and take up extra nutrients and nitrates as they flow through the beds. The reeds sequester nutrients from the waste water as they grow in their fibres and leaves. Small aquatic organisms and bacteria further break down and filter out pollutants and heavy metals in biological processes.

Reed beds are a typical example of how wetland plants are used to clean waste water but there are many other wetland planting types for water cleansing and filtration. The three main wetland planting types are: Submerged plants which provide oxygen to the water, Marginal’s which allow water to pass through their roots and shoots. Floating plants such as Duck weed. All of these have their place in the cleaning of waste water from urban environments. In most cases a combination of swales directing flows through reed bed systems to a series of retention wildlife ponds is the most effective interconnected system to direct waste water ecologically back into the environment.


Picture

The three main wetland plant types can be implemented into a wildlife pond for maximum effect. These wetland areas can be designed into landscaping implementing sustainable landscaping projects. These wetland parks and gardens can be enjoyed by people for recreation as well as wildlife species.

The Benefits of Implementing Sustainable Urban Drainage Systems in urban areas with Sustainable Landscaping.

Global warming is bringing ever more humid, wet weather to the United Kingdom. But are we actually prepared for a wetter stormier future?

The extreme flooding events over the last ten years have cost the economy billions of pounds with no real guarantee this can be prevented without serious changes to our very old and out of date Victorian drainage methods.

The old concept of urban drainage planning was to take up water as quickly as possible and divert it away into our drainage network as quickly as possible. The problem with this is we know from recent events our drainage does not work and is completely unsustainable. Expanses of paved surfaces and areas of urban hard standing drain straight into drains and hence natural water courses allowing pollutants and toxins to run into the natural ecosystem. Water that years ago would have drained slowly back into the landscapes surface is now accelerated into pipes and concrete channels.


Picture


Within the last one hundred years we have lost over 80% of our natural ponds and wetlands with the wildlife that depends on them also. Most urban streams are wildlife deserts with the only species utilising there course ways being the urban rat.  As natural watercourses in towns have become the place of back alleys and industrial back routes they have become a host to anti social behaviour and places of general avoidance. To cope with ever larger amounts of surface run off authorities have built ever larger culverts and sewer channels creating unsafe playgrounds for urban youths and accelerating places that accelerate unsocial activities.

Ever larger drainage channels and culverts are engineering’s way to respond to the concept of getting water away as soon as possible but only add to the unsustainable drainage theories of the past. More unsustainable drainage means more accelerated storm water flow this requires more expensive dredging downstream removing excess sedimentary silt which blocks our water courses. The overloading of urban runoff routes means chemical spillages; toxic road pollutants, oils and dog fouling all find their way to our local hydraulic cycle.


Picture


Due to excessive amounts of runoff in modern times we have incorporated gulley pots along the drainage system which commonly get blocked which cost the local authorities hundreds of thousands of pounds a year to clear and maintain. Extra cost for a completely unsustainable system, the gulley pots also kill thousands of wildlife every year with frogs and newts being washed into these trap like pits.

In the past most of our waste water including sewage and urban surface run off systems were combined. This enabled a non sustainable concept of waste water to develop. Today run off and sewage drains are separate giving us the opportunity to deal with run off in a more naturalistic way.  It was very common in the Victorian era which founded our drainage network to conquer nature but modern thinking gives us the opportunity to revaluate this and come up with a method that works with nature for a solution to our urban drainage issues.

The concept of Sustainable urban drainage follows this methodology. Instead of hiding storm water courses behind concrete walls or along urban industrial wastelands good design brings this water into the heart and urban fabric of the community. Sustainable landscaping and ecological design perspective takes into account amenity value, recreation, pollution filtration and wildlife elements of urban water runoff into sustainable urban drainage solutions.



Picture


The concept of SUDS is simple designing a way for storm water to be absorbed back in to the ground as close to the source as possible. This makes the possibility of polluting our natural hydraulic ecosystem virtually nil with the added benefit of preventing flash flooding further down steam. This method of local absorption is known as infiltration. Fundamental SUDS examples of this are: permeable paving, filter strips natural wetlands, basins, retention ponds and bioswales. 

Polluted water from urban environments filters through ecological naturalistic swales and ecological landscaped vegetation zones filter out large pollutant particles before they continue into the main wetlands. Smaller toxic metals, oils and chemicals are filtered by the roots of wetland plants and microscopic wetland organisms such as bacteria. Basins and ponds give the ability for excess storm water to flood into in times of heavy rain. These have enough ecological landscaped areas in the form of depressions and retention ponds to absorb the most extreme flooding events forcing new development to design in recreational seasonal flooding parkland spaces. New housing developments with ecological sustainable drainage landscapes designed in are valued at 10% higher due to their scenic value adding another boost to the incentives of ecological and sustainable development and landscaping.

Picture

Sustainable urban drainage systems improve water quality no matter what chemicals human environments throw at them. It is estimated that half the oils which end up in the sea are not from oil tankers but the surfaces from urban roads and car parks.

By incorporating SUDS into urban areas you offer the possibility of ecologically cleaner environments and water courses. The ecologically landscaped parks offer recreational potential and wildlife reserves for children to engage in outside learning activities. Benefits of such outside learning and exercise are becoming more scientifically verified in the media. The potential for local eco gardens and school outside community classrooms are accelerated by these kinds of sustainable landscaped spaces.

The future of sustainable urban drainage in our urban fabric seems to offer unlimited benefits to the wider ecosystem and local population in terms of economics and recreation. Safety is always an issue when it comes to standing water and young children. Today health and safety correctness combined with other social fears have led to fears for children playing outside in naturalised environments. With the acceleration in modern technology and digital entertainment problems such as obesity and a lacking in communication skills are also an ever worrying problem amongst our younger generation. 

Safety features can be designed in including very densely vegetated pond sides including gently sloping ponds so they are safer than river. Children should be given the chance to access risks and experience water within the public realm. Natural wetland environments in public parks and gardens can be designed in a way that they are experienced but hard to actually access deep areas of standing water.


Picture

SUDS don’t just offer to save the economy thousands of pounds it offers the opportunity of recreation, education and sustainable urban water ecological management. By using good planning and ecological landscape techniques the future of our living environments can be a place for people and nature. Flooding and pollution of the natural hydraulic cycle can be a thing of the past.

How modern flooding can be solved with Ecological landscape design and Sustainable landscaping.

8/9/2017

Britain has seen record rainfall in the last few years resulting in catastrophic flooding which has cost millions of pounds to insurance companies and the UK tax payer. With trends in global warming resulting in more predicted heavy rainfall is it time to rethink our flooding & landscape strategy?

Many physical engineered flood barrier systems have added to the costs of these now familiar biblical flooding events with towns and cities still suffering significant floods and this is a typical modern scenario of man trying to fight nature instead of working alongside it. The truth is sustainable landscape architecture has had the solutions for this for many years!

Picture

All rivers and water courses have a source which is a drainage point two the water catchment or basin. The topography of a region combined with the ability of the landscape to absorb excess storm water will decided whether an area will flood an where a flood will take place.  There are three main reasons the UK has had increased flooding in recent times: intensive agriculture, increased rainfall due to rising global temperatures and the planning of our towns and cities.

In the past one hundred years our agricultural landscape has changed dramatically. The mechanical age has resulted in large areas of wetland being drained for farming. Tapestries of small farms encompassed by hedgerows with varying uses as nut orchards and hay meadows have been flattened to make way for big commercial agriculture. Indeed if you cast your eye over much of agricultural Britain you will see expanses of open fields with very little else.

A combination of varying land use, forested uplands, natural wetlands along river courses and a more vegetated countryside in general would allow the landscape to absorb and retain storm water in times of heavy rain. The small farms across the country would all have at least one large pond for livestock to drink. Farm ponds like these retained water within the landscape and seasonally flooding meadows and wetlands absorbed water which now runs into rivers and floods developments.


Picture

It is quite obvious that recent industrial times are warming the planet we are already a whole degree warmer than before industrialisation and winters have been noticeably wilder in very recent times. As winters have got milder summers have become wetter with warm humid air creating heavy precipitation throughout the season.  As our climate continues to rise heavy rainfall patterns look to become more and more common.

One of our biggest design flaws is our attempt to suppress natural process within our urban development’s channelling natural watercourses into concrete strait jackets which burst at the seams and turn into dangerous rapids during heavy rain. Block after block of urban development increases surface runoff into narrow pipes and channels feeding into the same tight water sewers which are already full causing them to burst their banks and flood surrounding developments. As our urban drainage networks are already stretched when prolonged periods of heavy rain arrive the potential for displacement of thousands of people and insurance claims in the millions becomes a quick reality.


Picture

Ecological landscape design and sustainable landscape principles always aim to work with the natural process of the environment. When planning new towns and Cities rivers and green corridors through the landscape should be enhanced as green highways through the city allowing for cycling, walking and pleasure. The green river corridors should be designed in away the parklands on either sides can seasonally flood in times of heavy rain. Not only can these green ribbons through the city absorb flood water they can also be an opportunity to grow food and watch wildlife.

Green roofs are an underestimated tool in the quest to reduce surface run of in our towns and cities the reduced run off from vegetated roofs or any green space in the city for that matter can dramatically reduce flooding in urban environments.

Car parks and roads are another issue in surface run off in towns, not only is storm water carried quickly into the drainage network dangerous toxic metals and salts from these pollute surface run off which flows into our rivers poisoning wildlife and the water cycle.


Picture

Using sustainable landscape urban drainage road run off can be channelled into seasonally flooded wetlands in adjacent landscaped parks. Wetland plants in these retention ponds can filter these toxins out of the water in an ecological way. Drainage retention ponds also encourage wildlife helping to increase biodiversity. Using this kind of naturalistic ecological landscaping in public parks we can do much to reduce flooding, purify toxins and increase the health of our neighbourhoods for people and wildlife.

As surface run off is one of the biggest contributors to urban flash flooding permeable surfacing should be used where ever possible. Good examples of these are rubber safety surfaces in playgrounds and resin bound aggregates.
Picture


In terms of regional ways to reduce flooding and slow down water flows across larger catchments and basins there is one major solution. Restore naturalistic seasonal flooding wetland habitats to lowland areas. This will both encourage wildlife and retain storm water naturally. Even the vegetation types of wetlands such as reed beds enable a greater absorption of fast flowing water from heavy rain. These can be further improved for flood prevention by creating overflow areas consisting of dry seasonally flooding depressions in the landscape planted with water loving species.

Picture


Rewilding mountainous and upland areas can do much in reducing flooding in lowland areas. Primarily this comes from planting more trees and having more vegetation in general. Once again one aspect of ecological landscaping and design benefits multiple environmental factors. More vegetated naturalistic environments increase biodiversity, can produce food, provide recreation, sequester carbon from the atmosphere and reduce flooding alike. Sustainable landscaping is recognising the environments natural processes and working with them to find solutions for both wildlife and people into the future. With intelligent ecological  design and sustainable landscaping we can make urban flooding a thing of the past and a greener, wilder more productive countryside.

A highly recommended short video about the opportunity water brings in sustainable landscape design. It has been a common theme throughout out history of channelling water into narrow corridors and sewer like pipework. This very outdated method of drainage is usually a missed opportunity to create a better more diverse landscape and   actually increases the risk of urban flooding.  The video was created by the Landscape Institute.

How Sustainable landscape design & Ecological landscaping can prevent global food shortages and create healthier, happier populations.

One of the biggest problems facing civilisation today is food security. The relatively recent boom in population growth has required ever more commercial intensive agricultural practices to sustain it. The problem is there will come a point where a link in the chain will break and the human race will have to ask the question ‘can we go on using unsustainable methods of producing crops to feed ourselves’? I am sure that sometime in the not too distant future will see a few crisis that will make us understand how fragile our food supplies are especially in intensive modern monocultures.


A direct product of our modern mono culture farming methods has resulted in some of the most nutritionally devoid diets in history. Diabetes has now overtaken heart disease as the leading cause of premature death in the UK, both conditions can be directly attributed to the sort of diets encouraged by our current farming methods.

Picture

Highly processed carbohydrates and sugars are a common vice of the western world’s staple diet and are not by any means natural for our species as great apes. Fruit, nuts, vegetables, insects and occasional small mammals are a natural human diet if our close related cousins are to represent a precedent. Fossil fuelled agriculture has made it easy to harvest wheat’s and grains, annuals grown on mass a diet more commonly in nature held by species with higher metabolisms such as rodents and birds. In historical times foods such as bread and sugar were seen as holy as their high energy content could be the difference of living and starving. It is no wonder our love for sugars and starches have continued through the ages but do we eat too much simple sugar in our diet? It is the effect these types of foods on our hormone insulin which has resulted in type two diabetes becoming such an epidemic problem today.


Picture

By eating less meat we as humans significantly reduce our impact on the planet. A vegetarian has one third the ecological foot print as a meat eater with a diet high in animal fats being a lead contributor in heart disease cases in developed countries.


It is not just the type of foods we eat that make us more prone to disease and having a high ecological impact. Modern agriculture also uses a high level of herbicides and pesticides of which the links to human health cannot yet be fully known. Just because there is no scientific link between a compound and human health does not mean it does not have the potential to cause mutation in cells or make us ill.


Picture

The problem is in a world of high mortgage’s and rents with higher and higher densities of people living in cities how can anyone have the time or room to grow and harvest enough food to live. Once again sustainable landscape planning can be the key. It was landscape architect Ian Mc Harg who first found the link between high density environments and the reduction in human health and social cohesion. Urban agriculture and farming has revolutionised methods of growing food in urban environments some using permaculture design principles to produce a surprising about of food within a small space. There is no doubt sustainable landscaping techniques such as herb walls, rooftop gardens and city allotments can produce a great deal of produce but a larger ecological planning strategy is needed to help us be self sufficient in food.



Picture


Current planning policy in the UK is quite out of date in its underlying founding concepts from the turn of last century. In the high industrial times of the early 1900s towns like London were over populated and dirty mainstream landscape planners believed green lungs in the form of parks and green belt areas should be created to deal with the problems of urbanism. The concepts were correct for the time but today a decentralisation of towns and urban areas would allow for more spread out human settlements with abundant garden space and community growing areas for local food production.

The idea of a new generation of nine to five urban farmers coming home from a long day at work and getting the spade out seems a farfetched notion but it does not have to be. Our current theory of growing vegetables and farming for that matter bases most of its practice in growing annual crops. Rows of delicate young salad leaves and root vegetables which are quickly engulfed by pioneering weed species making annual vegetable growing a timely process.

Picture

The future of food production should rely on less energy input ecological permaculture and agroforestry systems. Such systems rely on more perennial vegetables and growing a varying array of crops in a permanent forest structure.  A typical permaculture or agro forestry food forest would have a top canopy of fruit, nut trees with smaller bushes in the medium canopies with fruits and edible leaves. At lower levels there would be tuberous plants, perennial vegetables and herbs hence catching the suns energy at different levels for maximum food production. Martin Crawford at Agroforestry UK points out that if planted for maximum yield when established could feed ten people per acre with very little energy input. This is significant as modern farming will only usually sustain 5 people an acre with the use of fossil fuel energy.


Picture

Housing developments of the future could utilise the fundamentals of ecological landscape design and sustainable landscape practices integrated with food forest systems to feed local residence. Abundant naturalistic forest environments will also encourage wild species which could be harvested as food for sport. Aquaculture wetland systems can also be used for sport and the rearing of fish for food. Sustainable landscape planning could create healthier wilder living environments with fitter people.

The one thing that makes forest gardens not a viable option for food production in the industrial world is they cannot be harvested in a mass mechanised fashon. Different crops are ready to harvest at varying times of the year and from different orientations to the ground. Forest gardens require knowledgeable skilled plants men to harvest the food types within a forest food system. To add to this forest gardens can have over 200 edible species per hectare which is a huge contrast to the average 20 consumed by most of the population.


Picture

A future world with low energy input food forest systems could provide alternative educational activities for schools and young people. Careers in harvesting, planting and maintaining food forests could be subsidised by affordable woodland homes in a new ecological local economic framework. Locally produced food and eco tourism could work together boosting rural economies. New temperate permaculture food types will need a new knowledge of cooking an extremely diverse diet of green vegetables, fruits and nuts including many plants with high medicinal values.


Picture

So it seems a more wild diverse food system based on natural ecology could increase locally produced food production, boost local economies, ensure families re-connect with nature, help mitigate causes of obesity, provide more opportunities for recreational activities and ecotourism. Ecological landscape design and sustainable landscaping techniques could provide the tool box to start to solve Britain’s problems of geographical divide, housing crisis, obesity, biodiversity loss and food security.

How Ecological & Sustainable Landscaping Can Halt The Destruction Of Global Biodiversity.

2/20/2017

0 Comments

A very common concern mentioned in the media is the accelerated loss in global biodiversity we are currently facing but what danger does this really cause to our daily existence? This element to biodiversity loss is rarely tackled in the media however it is the most extreme and worrying one. Indeed the loss of majestic mega fauna such as the Tiger and Elephant are catastrophic but our loss of local natural habitats and insect life pose a more instant threat to our existence.

It should be noted that one third of all the worlds agricultural crops depend on pollination from insects. Productivity from these crops has seen a dramatic reduction especially in the last 50 years. But it is not just the crops which directly rely on pollinators which are at risk from the loss of biodiversity. The majority of food produce found in our supermarkets today are grown by large commercial monoculture agricultural systems. The soil they are grown in is bleached with fossil fuel based phosphates, nitrates and potash three nutrients that are essential for plant growth.  In nature these nutrients are provided by a complex ecosystem of mostly microscopic life including many microbes and fungi. On average a healthy plot of land will contain two tons of soil life per hectare. In a natural soil ecosystem animals, insects, plant species and fungi will work together to recycle nutrients in the system and maintain soil fertility. Current agricultural chemical processes have meant soil microbes and beneficial fungi have been in decline. This has led to soil degradation a process leads to a lack of soil structure and growing viability. It is becoming more obvious biodiversity within our soil and its interrelations with the wider ecosystem could seriously damage our ability to feed human populations.

Picture

There are critics which argue that we can grow crops today in hydroponic systems which do not require soil but they are seriously fooled by the reality of the fundamental mathematics involved. Using current modern industrial methods of farming we on average consume 5 calories of fossil fuel energy to produce only 3 nutritional calories. The new indoor hydroponic systems rely on three times this energy amount for the same return with large flood lights and chemical feeds.

It is true that the current way human beings are feeding themselves in the developed world is completely reliant on oil and will not carry our existence into the next quarter of a century at current levels. The only way we can ensure food production of any sort will require the balance and interactions of wilder ecosystems with their sustainable nutrient cycles and renewals. It is the fundamental concept of a complete healthy interrelated ecosystem that is the only way to ensure human food security into the next century.

So it seems biodiversity is directly linked to our survival today but does this mean we have to wait until the reduction in global oil? How long could that be? Current predictions of oil depletion have so far have been completely wrong but one thing is for sure we are either at a peak or have peaked. There are a number of scenarios and indicators which means declining biodiversity could be the end of human civilisation as we know it a lot sooner than we could have ever imagined.



Picture


The reason all types of species including, plants, trees, bacteria, microbes, fungi, reptiles, birds and mammals are all needed for each other’s survival is due to millions of years of interaction and interdependent cycles. If one species ie humans find a way to partially separate themselves from the system an ecological deficit will occur. Such deficits will always be balanced by nature in the end this is a fundamental concept of science. A good example of this is our discovery of antibiotics which has aided the human race to a population explosion over the last one hundred years. In recent times the scientific discovery some bacteria are gaining resistance shows the Russian roulette we are now playing with our place in the world’s ecosystems. As our crops become more engineered and highly bred for faster quicker yields with resistance to this resistance to that we could find our future crops could become so delicate and fragile to new pests and disease strains our species and modern world could quite literally fall apart in front of our eyes.


It is a fact that biodiversity lower in the food chain is fundamental to our future food security but what about the extinctions of Rhino and Tiger? Are they not as important to human survival? Rhinos have a very important role to play in the savannah ecosystem they have the ability to grind down invasive and fast growing brush allowing other smaller species to get a foot hold. Major carnivores such as Tigers keep herbivore populations fit and healthy consuming the slowest and most unfit animal’s only allowing survival of the fittest to breed and produce the next generation.


Picture


And so it is clear Biodiversity has some very complex and interrelated factors associated when we investigate the relevance to our own survival. One thing is certain a healthy ecosystem relies on all species to create balance whether it’s a stalking tiger or bacteria in the soil our future as a species relies on the ecological health and balance of our common environment in which we live.
In order to address some of the symptoms of biodiversity loss landscape use and design has to be at the forefront of solving the decline of species. In urban environments sustainable landscaping such as naturalistic parks and living roofs can clean pollutants out of the air reducing the poisoning of insect and aquatic life. Such ecological landscaping in towns and cities can provide nesting opportunities for insects, mammals and birds encouraging wildlife to live in amongst us pollinating our crops and feeding on pests. 
 
Using sustainable landscape architecture and planning to integrate wilderness, agricultural and urban environments stimulating interaction with nature and encouraging locally produced foods from farm and wild produce. Sustainable landscape planting schemes can be more diverse and incorporate plants which provide more pollen for insects and butterflies.  


Picture


Larger regional strategies can be drawn up to connect wild areas and re wild large sections of our countryside. Woodlands can be combined with agro forestry permanent food systems and orchards producing fruit and nuts for the populations. Large areas of wild woodlands can be managed for sustainable timber creating rural jobs and boosting rural economies. Such strategies could curb negative effects and a recent distaste for globalisation allowing subsidised housing for rural workers in new eco communities. These local traders relieved from the financial pressures of the housing crisis would enable local crafts and business to flourish such as wood carving, mushroom cultivations and specialist game keepers.

Large regional ecological landscape planning could create a more diverse spread out patchwork of interrelated wild, agricultural and urban housing boosting biodiversity and the economy at the same time. Re introducing once common extinct species such as the wolf and bear would set a better example to developing nations that the future of the developed world can mean more wild environments. New wildlife eco tourism and game sports could be encouraged to boost conservation and development revenues allowing a future where biodiversity levels are accelerated and local economies boosted.

It is clear that biodiversity is vital for our survival especially for the future of our species but with using the fundamentals of sustainable landscaping and ecological landscape design we can create a less centralised world and more diverse landscape where biodiversity and the quality of people’s lives are enhanced.

1. Reversing the loss of biodiversity.

Halting Biodiversity loss is one of the most underestimated threats to modern human civilisation. Whether preventing the loss of major predators such as the Tiger or local urban wildlife such as bees and butterflies the reduction in life diversity on our planet is a serious problem for the future of the human species.

More than one thirds of the world’s crops rely on pollinating insects to productively produce food. The understanding that all organisms are a part of a complex web of interactions and ecosystems means the loss of a single species can result in dramatic consequences for our future food supplies. Fossil fuels have given humans the opportunity to industrialise food production, modern agriculture however is completely unsustainable. For every 5 calories of oil based energy pumped in to our farming we only reclaim 3 calories of nutritional energy back saturated in herbicide and pesticide residues.

Picture

Natural biological systems which ensure soil fertility, pollination, pest control and species health are directly being destroyed by modern forms of agriculture. We are sitting on a time bomb of disaster where the natural systems which support our food security are depleting. Humans are simply propping up our future survival on the back of fossil fuel energy.

One of the greatest attributes of sustainable landscape design is its response to natural systems and natural process. Species that are local or have a specific niche are incorporated in to landscape construction schemes where they need no artificial help to thrive such as the Greenwich Ecology Park in London. Green corridors and places where wildlife can shelter help to increase species and boost local ecosystems. Diverse planting design and linking places of ecological importance help to reduce the loss of biodiversity which will intern aid the food security of the world.

Larger regional ecological and sustainable landscape schemes can link wild habitats through the countryside giving opportunities for larger species to flourish which intern can boost local rural economies and enhance more sustainable future food production.


2. Producing more local organic food.

One of the ways to ensure a sustainable healthy human population for the future is by reducing our dependence on oil to produce food. Ecological and sustainable landscaping implemented around our homes and urban environments can create productive beautiful environments for us to live and work.

Community growing areas and allotments can be a place where people come together to socialise and grow food. Raised beds and urban food production planting areas can become landscape features ensuring a local food supply free of pesticides and herbicides.


Picture


Good sustainable landscape design can implement various methods and responses to local conditions to maximise beautiful environments which also have a social benefit as well as agricultural one.

Landscape design systems such as permaculture and food forest systems can provide local food, encourage biodiversity, and create a sense of community. Producing locally grown food is the only way to ensure food security in a world with reducing supplies of fossil energy. Sustainable landscaping implementation can help create living environments where an ecological food supply becomes a reality for the future of mankind.

3. Prevent flooding


With melting ice caps and years of increasing rainfall flooding is becoming a threat to our economy and security. The problem with modern urban drainage systems is water is treated as a waste product, not a resource. Excess storm water is channelled into narrow sewers with channels accelerating water flows increasing flooding risk. The majority of water accelerated through our drainage systems carries chemicals, dangerous metals and pathogens into the drainage network usually spilling into our local hydraulic ecosystem.


Picture


Current methods of modern drainage accelerate flash flooding and increase the amounts of pollutants in our environment. This directly poses a threat to our health and the increasing potential of flooded homes and farm land.

Ecological landscape planning and sustainable landscaping can implement many landscape types and strategies to reduce flooding and the environmental calamities it brings. By implementing sustainable urban drainage solutions or S.U.D.S water can be managed in an ecological way preventing flooding ensuring a healthier environment.

Picture


Landscape drainage installations in the form of S.U.D.S include features such as permeable surfacing including, gravels, block pavers, resin bound aggregates and ground stabilising grids. Bio swales, retention ponds and wetlands enable polluted water to travel through dense plantings of wetland plants which filter and clean urban water runoff. Ecological landscape planning and construction can capture urban storm water with a  vegetated environment absorbing  water and cleaning it in an ecological way. Wetlands and ponds also give the opportunity to provide wildlife habitat, recreation and ensure the reduction of urban flooding. This will ensure a sustainable hydraulic solution for the future of our urban developments.


4. Greening our towns and cities


Modern cities are a true testament to the success of the human species living together in an organised sophisticated jungle of services with complex economic structures. They are however far from the hunter gathering societies or small agricultural settlements from which humans have been a part of for thousands of years.

Modern towns and cities are on the flip side completely reliant on industrial fossil fuelled systems which do not represent a human society in harmony with the natural ecosystem and one that would rely on the suns solar energy of today instead of that of the past. Indeed it is not only modern towns and cities unsustainable attributes which are creating problems for the longevity of the current developed world; there are some other indicators which show humans do not benefit from a life of concrete metal and glass.


Picture


It has been discovered that high density environments accelerate the decline of mental and physical well being in the people who live within them. Addiction, mental illness, stress, anxiety, obesity, depression, these are all modern illnesses associated with high density urban environments. It has also been noticed that animals in bleak zoos with grey facades and limited vegetation display irritable and degenerative mental, social behaviours.

From environmental point of view high density urban environments don’t score well either. In summer the hard surfaces of the city heat up causing the ‘heat island effect’. This causes unbearable temperatures and exposes people to airborne toxins from our car engines and industrial processes. An excess of hard surfaces cause flash flooding which pollute the hydraulic cycle from our city run off. Social breakdown, obesity resulting from a sedentary lifestyle and a lack of spiritual delight make urban dwellers less happy than their rural counterparts.
There are numerous ways these problems can be reversed by ecological and sustainable landscaping within modern urban environments. By re-vegetating our towns and cities we can actually reverse many of the negative attributes of modern developments. With intelligent ecological and sustainable landscape design our urban spaces can be planned with a less nucleated centres which allows for the integration of agriculture, animal husbandry, recreational and wild spaces. The social and economic benefit this creates is immense. City dwellers who have suffered addiction, metal health problems and criminal convictions have the opportunity to subsidise their housing with community efforts and local farming projects. Children from cities can enjoy fresh air and the opportunity to learn and exercise in a natural environment. These forms of activities in urban settings have been proven to improve mental health, well being and fight obesity.

Picture


Re-designing our towns and cities can feel like a dream away with no expectations of bulldozers and re-planning coming any time soon but the idea of re-greening or urban towns can be implemented for a better future.

Sustainable landscaping techniques such as green roofs, green walls, urban farming, permaculture, agro forestry and wildlife habitats enables towns and cities to help in solving some of the problems people face in the urban fabric. One thing that binds all these concepts together is the basic re vegetating of our urban spaces. This will reduce flooding, improve air quality, insulate in winter, cool in summer, provide recreation, improve metal health, encourage physical activity and heal the human spiritual void of no interaction with the natural world.

5. Re-wilding areas not suitable for farming.


No proposal causes more debate especially in Britain over the re wilding and subsequent reintroduction of native extinct species such as the European Brown Bear, Wolf, and Lynx.


Today if you look at a satellite image of Europe and the United states you will see lowland fertile areas reserved for farming and upland areas covered in trees and wild habitats. In Britain this is not the case our hills and mountains are very bare and mainly subjected to highly subsidised forms of grazing agriculture commonly rearing sheep. The problem is the rearing of sheep is economically unviable and simply could not continue without tax payer’s money. In a world where we need to become more sustainable this kind of upland farming surely should become a thing of the past.
It is the heavy grazing practises of sheep rearing which prevents the natural succession of scrub and forest species which keep upland areas barren and devoid of life. Not only do sheep do this but the absence of large predators means large populations of deer graze what areas are not farmed and every year have to be culled to reduce surplus populations.


Picture

An aspect of re-wilding that is rarely discussed is the symbolism it embodies and the outward message of hope it gives. In Britain we campaign and speak out about the loss of large African species at threat from extinction but we fail so terribly in reintroducing our own large native species that we ourselves hunted to extinction! This is simply double standards and makes us look a little pathetic in the international conservation arena. I think Western countries could lead the way in applying re-wilding to areas which are too highly subsidised in money and energy terms to farm.

In Britain it is stated all too often that we are a ‘crowded little island’, nothing could be further than the truth. Most national parks across the wild areas of Africa and India are in the range of 250 – 400 square miles and within that range host thousands of large prey species and on average 40 large meat eating predators such as leopards and wolves. The areas we are talking about here are comparable to Dartmoor at 350 square miles and the Chiltern Hills North West of London both highly populated southern parts of the UK.
As an example the Chiltern Hills covers the counties of Berkshire, Buckinghamshire, Hertfordshire and Oxfordshire. The upland areas are already set aside for forestry and recreation. It would make absolute sense to plant more forests in these areas and boost the ecotourism the region already generates. This could perhaps offset the carbon footprint of the controversial HS2 high speed rail line. Although the region is not suitable for large reintroductions the lynx could help to keep deer numbers under control. Only being an hour’s journey from the capital The Chilterns could offer an extra wild day trip for international tourists to London.


Picture


The truth is most of Britain’s population live in high density urban centres such as London, Birmingham and Manchester. For anyone who rambles across large parts of the rural countryside especially moor and upland areas you can normally spend all day without encountering anyone. I would say that anyone that uses the term crowded little Island does not get out into the countryside very often and probably lives in a crowded city!
It is a fact that re-wilding the correct parts of our countryside will help us to become more sustainable and economically viable as a country. The increase in woodland trees and vegetation will absorb flood waters, boost our wildlife species, sequester carbon from the atmosphere, provide sustainable timber, create eco tourism, and clean our air of pollutants. This is a far better option than farming one sheep per hectare at an economic loss.
New upland forests could be planted with a mixture of native and agroforestry tree species allowing us to farm woodlands for food production and edible fungi inoculation. The new wild uplands can be mixed with wild food crops such as hazel nut orchards and truffle plantations. Wild delicacies such as honey production could create business opportunities for rural communities.


Picture


From existing rewilding projects the full benefits of reintroducing large animal species has shown the direct landscape benefits of reinstalling a natural ecosystem. In Yellowstone national Park in the USA the reintroduction of wolves and subsequent studies of the new packs showed they help shape the environment in ways we never knew possible. 
The wolf prey species such as deer and elk were always kept moving allowing browsing to be more evenly spread out across the park. This allowed regeneration of more woodland especially around rivers. Beavers returned on their own and the whole natural ecosystem started to recover with species that were extinct returning to the park after 70 years. It had become clear that the interconnectivity between species was such a powerful force catalysed at full speed by the reintroduction of large predators back into the landscape.

The idea of reintroducing predators or large fauna such as elk back into Britain always comes up against strong criticism but in a world of globalisation and wealth being concentrated into city centres especially in the south of the country we are missing a huge opportunity in creating an eco tourism explosion and boosting our rural, wild economies.
One of the models the UK could use is the Bialowieza National Park in Poland home of the magnificent European Bison. Every year a few animals are allowed to be hunted by wealthy businessmen generating many tens of thousands of Euros for the park to spend on new projects, the park attracts thousands of visitors worldwide every year. 


Picture

Wild wilderness environments can also be utilised by the government for eco therapy schemes and youth educational purposes.   Our new wilderness environments can help in the development of young people who are not academic to learn new skills. City dwellers with social problems could have the opportunity to reconnect with the spiritualism of nature.
Even though re-wilding is a controversial subject the facts cannot be denied it gives us a real chance to develop new uses for the more wild and remote parts of the country both socially and economically. By using ecological design and sustainable landscaping a re-wilding of our rural environments can help us conquer the sustainability challenges we are sure to face over the next century.


6. Reducing carbon from the atmosphere.


The rising levels of Carbon being released into our atmosphere is of great concern by world leaders who have realised its impact on raising global temperatures and drastically changing weather patterns.
Some of the main catalysts for accelerating carbon release into the atmosphere are the combustion of fossil fuels, cutting down forests and ploughing the soil.  Pretty much by default we have no choice in our day to day lives to reduce the release of carbon into the atmosphere. The breakfast we eat our journey to and from work our leisure activities are all for the most part reliant on carbon release.


Picture


Our daily lives ability to reduce carbon can be manipulated with sustainable and ecological landscape design and planning.  Designing regional landscapes which allow us to work, live and grow food within more local structures will dramatically reduce the amount of carbon we release. Sustainable eco developments combined with local working could reduce our carbon foot print by a huge 80%. With a rise in technology, the internet and local renewable energy creation working from home is today a very real prospect.
Sustainable landscaping on a local level can also help to not only reduce carbon but actively sequester and store it back into the landscape.  By re-vegetating roofs and buildings we can help to lock carbon into our urban centres. By growing more trees and woody plants we actively allow carbon to be captured from the atmosphere and stored in the soil through the plants roots.
By allowing naturalistic planting schemes organic recycling can take place within the landscape. Dead plants can decompose back into the soil adding to the amount of humus within the soil. The larger amount of dead plant matter in the soil increases soil life which intern locks more carbon into the soil.


Picture


No dig landscape schemes with more ecological forest structures dramatically increase carbon capture and storage. Every time we plough or dig the soil large amounts of carbon are released into the atmosphere so by allowing the soil to be left as in nature will help microscopic microbes to build soil and increase carbon storage. Forest gardens and food forests can allow carbon to be locked up within the trunks of trees with the added benefit of providing a sustainable source of food production and habitats for wildlife.
By using sustainable landscaping and ecological landscape design we can incorporate carbon capture and storage on a level much more efficiently than artificial methods. By planning our infrastructure better and working with nature we can help reverse climate change and carbon release for the future.


7. Reversing soil degradation and creating soil.


Soil degradation is an ever growing problem in the world today which is directly linked to biodiversity, modern agriculture and food security. It is probably the most underrated potential catastrophes waiting to happen in our modern times.

It has been estimated that in the last 50 years we have lost a third of all soil on earth through erosion and degradation. It takes several millions of years to form topsoil and it is a living breathing entity full of organic life. Not known to most people the Middle East used to be the most fertile place on earth and saw the birth of agriculture as we know it today. Ancient pictographs show large cattle pulling wooden ploughs from ancient Egypt to Iraq.
Soil erosion, desertification and degradation has become a huge problem which can be directly associated with thousands of years of heavy ploughing and soil disturbance. Continued ploughing over many years releases carbon from the soil with sunlight bleaching microorganisms that maintain fertility moisture and soil structure. When these practices go on for years without any replenishing of organic matter and nutrients the ecosystems within the soil dies leading to soil which is effectively dead.

In nature the breaking down of organic matter including dead trees, plants and animals allow the transition of nutrients through natural systems the soil is a vital part in the cycle of life and fertility. Modern agriculture does not allow natural soil fertility processes to take place forcing productivity with oil based synthetic fertilisers. These cause havoc within the soils microorganism processes leading to reduced humus content and moisture retentive qualities. Mycorrhizal fungi which mitigates imbalances within the soil by moving around nutrients is disrupted and depleted leading to soil damage which is very hard to reverse this results in ever increasing regional dust bowls and unproductive farmland.

Picture

The only real solution to the potentially catastrophic issue of soil degradation is by rebalancing nutrient exchange within the landscape. In the past before industrialization oil did not give us the opportunity to take a short cut to natural soil fertility exchanges. Crop rotation where hungry crops would be followed by nitrogen fixing crops and left fallow for nature to replenish fertility were the norm in farming practices.

By implementing sustainable landscape systems through ecological design soil fertility can be maintained and enhanced by thinking locally about the recycling of nutrients within a food system. Aquaponic fish rearing systems are a good example of this where low energy interventions combine to use elements and nutrients to where they are needed for maximum impact. The waste products from fish can be directed to crop growing beds which benefit from the extra nutrients, in turn the water is filtered and cleaned for the fishes healthy growth.
In ecological landscaping ethical design systems like those found in permaculture can plan for the recycling of elements within a system so healthy productive environments are created and enhanced. During the design process landscape elements and functions are realised in their simplest form and joined harmoniously in landscapes which increase soil fertility, increase biodiversity and produce organic food.

Picture

The power of sustainable landscape design and construction is its fundamental values of replicating what happens in nature to solve problems. This can be incorporated into ecological landscape proposals by replicating natural woodlands. Woodlands are the low energy alternative to heavily mechanised and managed farmland. The fundamental elements of human survival is capturing and utilising the suns energy. Nowhere else is this more efficiently done than in natural woodland of varying canopies. By implementing techniques used in agroforestry to produce productive systems which recycle nutrients in a natural way is a very effective way to create environments which enhance soil life.

More forest based landscape types are a sound way to reduce erosion and ensure the component parts of sustainable soil fertility are encouraged. By allowing dead organic matter to be broken down within woodland environments you can boost fertility with almost zero energy input. This is the most sustainable method of preventing soil degradation in the world today while ensuring the preservation of biodiversity and reducing climate change.
The fundamentals of agroforestry and permaculture give sustainable landscape planning extra tools in landscape design to help protect and build soil. The way we landscape our countryside as well as local living environments is going to be vital to ensure healthy productive soil into the future of human civilisation.

8. Sustainable living community landscape planning which enhances society cohesion


One of the big social issues of recent times is globalisation and its effects on our population. The benefits of modern advances such as the internet are clear but living in a world with lonely elderly, childhood obesity and family breakdown is our current model of modern society working?
An ideology of a world without poverty a futuristic vision where people just become richer and richer and everybody has a good standard of living is a nice idea. The question is can this vision be sustained? Will it really make us as people happier? Unfortunately the reality is our fast growth economies rely on the exploitation of poorer people in poorer countries whilst only small numbers of the people in the richest countries benefit.
Many working class populations who live in richer countries have found themselves with no real opportunities with jobs and work opportunities moved to cheaper overseas workers.  The last 50 years has seen an explosion in city populations with rural communities shrinking as mechanised food production and large supermarket chains make farming unprofitable.


Picture

Large bustling high density cities which promise the dream of wealth and prosperity are usually overcrowded with stretched services and health care. The centralisation of our economies have rocketed house prices to an unsustainable level allowing speculative investors of the super rich safe places to stash their capital.  This has meant normal working families cannot afford to live secure lives in the ever debt ridden towns and cities.

Landscape architect Ian Mcharg and the founder of modern GIS mapping systems discovered a direct link between high density environments, social break down and metal health problems.  It seems no surprise that in nature without the exploitation of fossil fuels 0ne human being could only be sustainably supported in very low population densities.
It has been observed over history that small resourceful rural populations have a very strong social cohesion and community spirit. Even in the developed western world immigrant minorities from poorer farming back grounds seem to have stronger family structures and relationships. It is clear that human beings were meant to live and are happier in smaller rural communities with a strong community spirit.


Picture

There are many ways sustainable landscaping and ecological planning can respond to this. Sustainable living communities could be woven into the rural fabric of the countryside to help reduce the housing crisis. Housing rent subsidies could be offered to those who produce food or engage in community efforts. Sustainable landscaping could create naturalistic food production such as fish ponds and food forests. By boosting rural economies with smaller diverse farms we could offer a parallel local economy alongside a global one. Eco homes and developments could help in training young people in construction skills and help start thousands of new ecological jobs with less aggressive house prices in rural social housing communities. Careful planning with sustainable landscapes could create a diverse tapestry of new land use, skills, and trades and specialised farm products to boost exports to world markets.

Solving the issues of a modern globalised world is a complex task but to realise a world with a local, rural booming economy as well as a centralised global one is a sure way to realise a more equal, future. Sustainable landscape design usually thought of as a limited symbolic installation can have a far bigger holistic potential to make the world a more sustainable, prosperous and happier place.
