How do you develop plans and strategies for more sustainable neighborhoods?

 


The Built Environment Sustainability Tool enables the development of sophisticated and responsive plans and strategies to support improved local sustainability. These plans respond to and address gaps and aspects of current poor performance in the neighbourhood while supporting and improving aspects of good performance.

A wide range of options should be evaluated before a final selection of options for implementation is made. The tool should also be used to inform the mix, and sequencing, of interventions. Finally, detailed implementation plans and strategies should be designed and tested back against criteria in the tool to ensure that maximum impact is achieved.

The questions below, in conjunction with BEST, can be used to inform detailed implementation plans and strategies aimed at supporting sustainability.

New infrastructure

  • Is new infrastructure required?
  • Can existing infrastructure be used or adapted?
  • Can management and operation agreements be developed to support multifunction use of and shared access of existing facilities? 

Clustering and partnerships

  • Can clustering and shared use of infrastructure be used to increase efficiency and reduce operating costs?
  • Can partnerships be developed with neighbouring landowners and communities to increase the scale of interventions to support shared benefit and improved cost-effectiveness?

Linkages and synergies

  • How can systems be linked to reduce wastage and improve efficiency?  
  • Are there synergies that can be developed for mutual benefit?

Location and land use

  • Which location(s) for interventions can be used to support symbiotic relationships between functions and land uses?
  • Which location(s) for interventions draw on, and work with, natural and artificial features of the existing site to improve efficiencies and reduce operational costs?

Procurement

  • Which procurement processes are most suitable for creating local jobs and supporting local small businesses?
  • Which procurement processes can be used to reduce risk and improve local self-reliance concerning funding and long-term financial sustainability?

Construction

  • Which construction processes are most suitable for creating local jobs and support local small businesses?
  • Which construction products and materials are most suitable for creating local jobs and support local small businesses?

Operational management

  • Which operational management models ensure affordable local access and use of infrastructure for community benefit?
  • Which operational management models include governance mechanisms which ensure that infrastructure is responsive to local needs and opportunities?

These questions can be used to develop detailed designs, specifications, plans and implementation methods that ensure that the resulting interventions not only support local sustainability but also ensure that implementation processes are also used to support sustainability.

How do you develop more sustainable neighbourhoods?

Neighbourhoods appear to be complex and difficult to assess in terms of sustainability performance. A review of green precinct assessment tools for urban areas revealed that these tend to focus on environmental issues and did not take into social and economic issues. Many of the tools are also complex and do not encourage the involvement of communities and non-professionals. Also, many tools and rating systems are prescriptive and do not encourage or support the exploration of innovative solutions that respond to local opportunities and challenges.

The Built Environment Sustainability Tool addresses these issues by being based on a sustainability approach which includes social and economic aspects as well as environmental impacts. The tool aims to be simple to use and to encourage the active participation of all role players including local communities in assessing local sustainability performance and developing plans to improve this. It encourages a range of solutions to be explored and tested to support responsive solutions that work with local opportunities and challenges.  

The BEST methodology provides practical ways of developing more sustainable neighbourhoods that enable you to address the following questions:

  • What is sustainability?
  • What are the implications of sustainability for urban areas and settlements?
  • Do existing and proposed urban areas and settlements have the appropriate configuration and characteristics for sustainability?
  • Can this configuration and characteristics be assessed?
  • Can these assessments inform the development of interventions and solutions to improve sustainability performance? 
  • Are there ways of identifying the most optimum solutions and interventions to address gaps and rapidly improving sustainability performance?
  • Can sustainability plans and strategies be developed to ensure that sustainability targets are achieved in a structured, efficient and effective way?

Sustainable City Strategies





How do cities achieve strategic sustainability goals and change?

Cities are complex and involve many stakeholders so achieving change can be difficult, slow and require a wide range of mechanisms. It is not sufficient to have a high-level strategy; real change requires strategic targets to be integrated and driven by policies and programs and publicity and incentives to change behavior are often also required.

However, how do we know required change is being achieved? For this, effective monitoring and evaluation are required to understand what works, and what does not. This should track indicators that are linked to strategic targets and ideally be available in databases that are publically available and easy to access.

Interesting work in this area is the public open database developed by Charlottesville in the USA. This has 72 datasets which can be used to track performance in relation to strategic goals. This can be accessed here.

BEST 2013


The Built Environment Sustainability Tool is being updated. BEST provides a way of assessing the sustainability of neighborhoods. It can also be used to identify, test and compare interventions which can be used to improve the sustainability performance.

The tool is now being updated and includes some minor changes to criteria and provides for more detailed assessments. The BEST 2013 version is available for download from here. If you would like to use the BEST 2013 or BEST 2016 (new version) please contact us.

Mapping Diversity and Segration

New maps from Statistics South Africa show racial diversity and segregation in South African cities. These indicate that while some areas have become more integrated, others remain highly segregated.

Map of Johannesburg
Map of Pretoria

Patterns picked up in the maps include:

  • Central business districts (CBDs) have a high percentage of black African residents. 
  • Suburbs around CBDs generally have a high percentage of white residents. 
  • Townships, to the periphery of cities, have high percentages of black African residents. 
  •  More integrated neighborhoods appear to be suburbs near CBDs.

Human Habitat Creation

Habitats are defined as the natural environment in which an organism lives, or the physical environment that surrounds (influences and is utilized by) a species population.

This was the subject of an Institute of Landscape Architects of South Africa (ILASA) Seminar on 11 May 2016 and number of interesting presentations were made by John Masson, Siegwalt Kusel and Ben Breedlove.


My contribution was titled 'Human Habitat Creation' and addressed the following questions:

  • What is a sustainable human habit?
  • What are the specific requirements for a sustainable human habitat? 
  • How can sustainable human habitats be achieved?
  • Can a structured process be developed to enable this to happen at a neighbourhood level?

The presentations led to a very interesting discussion on how  methodologies used by Landscape Architects and Habitat Designers to design habitats can be applied at a wider built environment scale.  Copies of the presentation on gauge site soon.

What Africa will look like in 100 years

Interesting article in the Daily Telegraph on ''What Africa will look like in 100 years''. It makes the following assertions:


  • By 2100, it will be home to 4.4 billion people - four times its current population.
  • By 2050, more than half of Africa’s 2.2bn people will live in its rapidly expanding cities. That’s the equivalent of the population of China.



Given the implications of this huge growth, it suggests that current development trajectories are not promising and may not be able to  "deliver on the aspirations of broad-based human development and prosperity for all". 

Solutions recommended include;

  • infrastructure that improves  education,health and security and economic prospects
  • sustainable governance systems
  • embracing new urban paradigms,
  • better data, better decisions and
  • diversified economies

Know your city

Interesting presentation by Slum Dwellers International at a side event at the Habitat III Urban Dialogues conference on how communities are capturing data on their neighbourhoods and homes using a tool call ‘Know Your City. The tool can be used to capture a wide range of aspects of a neighbourhood including access to schools, clinics, the availability of electricity, sanitation and water, types of transport available and existing land tenure and organisational capacity.


The tool has been used for neighbourhoods in a number of African countries such as Kenya, Uganda, Sierra Leone, Tanzania and South Africa and has provided a useful basis for planning and discussions with local municipalities.

Cities as Engines for Economic Inclusion

Cities in developing countries are often portrayed as a source of problems such as high levels of unemployment, crime, poor services, overcrowding, pollution and ill-health. However, for the people who move to them, cities are seen as a means to a better life; a place to get work, start a business, and get an education. If designed and managed in a different way, can cities in developing countries enhance and direct this positive energy to build economic growth? Can the right characteristics and configuration be developed in urban areas to support positive development and avoid marginalisation? Is it possible for cities to be engines of economic inclusion, rather than the source of problems?



A recent study of Medellin in Columbia indicates that this is possible. It shows how the city has transformed its reputation as a city associated with crime and drug trafficking to a rapidly growing vibrant and inclusive economy. The study attributes this transformation to the following characteristics;

  • Cities do not make poor people. Cities attract poor and vulnerable individuals looking for a better future. Therefore, they must be accepted and integrated into the city's dynamics in order to foster their individual and collective potential. As shown by the 8.9% reduction in poverty between 2008 and 2013, according to Colombia’s department of statistics.
  • Architecture must never be a barrier to human interaction. The best way to reduce inequality is to promote connections and face-to-face engagement between individuals, without regards to their socioeconomic condition.
  • Public and accessible urban services reduce inequality. Allowing individuals across the board to enjoy a city, its surroundings and services are the best ways to make them active citizens.
  • Education drives change. Placing libraries and other cultural assets alongside public transport systems played a central role in selling the new brand the city wanted to create for itself, placing it squarely in the collective mindset.
  • Using technology as a means and not as the end itself. Medellin understood that whatever technological upgrades were needed, its success would rest with the function it fulfills and not in the scientific advancement it represents.
  • Last, but not least, placing culture high on the list of priorities helps to unleash a citizen's potential. Culture plays a major role in a city's transformation due to its ability to bringing people together, to move forward from traditional socioeconomic paradigms, and to share a vision and common values.

These characteristics are reflected in criteria in the BEST and SBAT tools which aim to support positive, inclusive development in urban areas and buildings. The tools identify infrastructure prerequisites required for inclusive sustainable development and measure the extent to which these are integrated in buildings and urban areas.

The tools have a very strong emphasis on the local area and on the nature of services, products and interaction that can be accessed within easy walking distance of a building. Thre is also a strong emphasis on local services such as access to education and health facilities as well as economic opportunities and productive technology. The tools are available to inform urban development and building projects and are particularly suitable for developing country contexts.

Urban Resilience

Urban resilience can be defined as the capacity of a city or urban area to cope with future shocks and change. There has been an increasing interest in this concept as a result of a sense of risk associated with climate change, economic downturn, social unrest and environmental disasters.

Systems with increased resilience, it is argued, enable cities to withstand shocks from man-made and natural disasters. A focus on resilience and the resulting strengthening of the self-organisation capacity of urban systems is also seen as a means of improving the sustainability of cities.




 The Assessing and Intervening: Urban Resilience Indicators report reviews concepts of resilience in order to determine key characteristics of the field and how these may be applied to and measured in, urban environments. Urban resilience indicator systems, tools and related literature are surveyed to understand the current debates within the field and to identify gaps and uncertainties.

The report reveals that there are different understandings of urban resilience and divergent views on how this concept should be applied and measured. An analysis of approaches is used to classify, and describe, competing urban resilience theories as well as their associated intervention strategies and indicators systems.

Within this framework the report charts potential future research areas that could strengthen the theoretical basis of the urban resilience field as well as its practical application through indicators and indicator systems, as means of improving the resilience of cities and urban areas.

The Value of Green Spaces in Cities

Increased incidences of mental illness have been shown to exist in cities. Conversely living near green spaces has been shown to reduce mental distress. A new study confirms the strong link between well being and green spaces. The study is based on 10,000 individuals finds strong correlations between the lower mental distress and well being for people who live in urban areas with more green space.




This confirms the importance of providing green areas in cities and specifically, near to where people live and work, so that this can be experienced everyday. Given that many of our cities are already developed and some have limited parks and gardens, how can more green spaces be provided?

This could be achieved by:


  • Taking over derelict urban areas and developing these as food and ornamental gardens.
  • Requiring all buildings to provide areas of green. On tight congested sites this could be provided in the form of planted beds, roof gardens and creepers or vertical gardens. 
  • Requiring buildings and sites which develop, or already have gardens, to make these publicly accessible and share these with neighbors and passersby. 

These requirements have been included as criteria in the BEST and SBAT tools, which aim to support the integration of sustainability into the built environment.

Local Climate Solutions for Africa, Dar es Salaam, Tanzania


Training on the Built Environment Sustainability Tool (BEST) was provided at a special Urban-LEDS pre-event training workshop of the Local Climate Solutions for Africa 2013 Congress. Professional staff and counselors from a range of municipalities were trained on the tool and used this to carry out assessments of areas within their municipalities and develop interventions to improve sustainability.

Participants welcomed the approach developed in the methodology and appreciated the simplicity of the tool. In particular, there was positive support for the way in which the methodology was able to address reductions in carbon emission reductions within a sustainable development framework. Participants indicated that this aligned well with sustainable development mandate of local government and the increasing pressure being experienced to accelerate service delivery.




Municipalities also indicated that the methodology and tool would be suitable to working with communities as it was simple and easy to use and provided a way of developing useful inputs for Integrated Development Plans (IDPs) and Spatial Development Frameworks (SDFs).

The Local Climate Solutions for Africa 2013 Congress was held in Dar es Salaam in Tanzania from 30 October to 1 November 2013. More information on the conference can be accessed here.

Public Participation and Community Empowerment

Greater Tzaneen has been selected as the greenest local municipality and Ekurhuleni as the greenest municipal municipality as part of the Greenest Municipality Competition run by the Department of Environment. Criteria used to select the greenest municipality include:

  • Waste management
  • Energy efficiency and conservation
  • Water management
  • Landscaping, tree planting and beautification
  • Public participation and community empowerment
  • Leadership and institutional arrangements

Participation in this annual competition is open to all South African municipalities and 111 municipalities entered.
It would be interesting to know more about the competition and the criteria. For instance, what might leadership and institutional arrangements refer to? Similarly, how might public participation and community empowerment be assessed? 
Public participation and community empowerment could be a highly effective way that municipalities support sustainability so it would be valuable to have more information. For instance, does this criterion include recognition and support for community- initiated projects by municipalities? If it does, sharing experience and examples of these types of projects could provide valuable learning that other communities and municipalities may wish to emulate. In particular, it could provide valuable models of how municipal resources can be used to respond to local need and create greater impact through community partnerships. In addition, encouraging and supporting active involvement by occupants in developing their neighborhoods may help alleviate the sense of frustration experienced by communities which is currently being exhibited in the increasing number of service delivery protests.



It may therefore be useful for DEA and their municipal partners to explore the potential of this idea further. A simple first step would be to provide communities with more detail on the competition such as the criteria and assessment methodology. This could be done through a dedicated website and could help stimulate valuable greening community-municipality partnerships.
The Building Environment Sustainability Tool (BEST) supports public participation and community empowerment by enabling local sustainability assessments to be carried out. Carrying a BEST assessment enables communities to understand the extent to which local infrastructure supports sustainability and helps identify interventions that can be undertaken to improve this. In this way the framework provides a structured process which can be used to develop local sustainability strategies and community-municipality partnerships.

Built Environment Capability for Sustainability

The World Wildlife (WWF) definition of sustainability as being the achievement of above 0.8 on the Human Development Index (HDI) and the achievement of an Ecological Footprint (EF) below 1.8 global hectares per person has a range of implications for the built environment (see Defining Sustainability). This definition is referred to as the EF-HDI definition.  These implications can be explored through the concept of built environment capability for sustainability.

Capability refers to the ability to do something, or the capacity to achieve a particular result. Built environment capability is therefore the capacity of the built environment to support the achievement of a particular result, such as the achievement of sustainability targets. This concept acknowledges that built environments, in themselves, are not sustainable or unsustainable. Even in areas where infrastructure has been carefully designed and managed for sustainability,overall sustainability performance can still be poor as result of users deliberately or unintentionally using this infrastructure incorrectly, or not using it all.

The concept of built environment capability is therefore not deterministic, and acknowledges human preference by affirming the importance of developing sustainable solutions that are preferable to prevailing or conventional solutions. This can be supported through high quality design and solutions which result in improved quality of life. 

Built environment capability confirms the pivotal role that the built environment plays in enabling, or precluding, human life and activity from becoming more sustainable. In particular, it asserts the ability of the built environment in enabling, supporting, and encouraging activities and lifestyles of occupants which are more sustainable.

Therefore in terms of the EF-HDI definition of sustainability, built environments can be described in terms of Ecological Footprint Capability and Human Development Capability.

Ecological footprint Capability
Ecological Footprint (EF) Capability describes the extent to which the built environment is configured and includes the characteristics required to support the achievement of ecological footprint targets as defined in the EF-HDI definition of sustainability. This capability therefore describes the extent to which the built environment supports required performance levels in areas such as ‘Food’,’Shelter’ and ‘Mobility’.

Human Development Capability
Human Development (HD) Capability describes the extent to which the built environment is configured and includes the characteristics required to support the achievement of human development targets as defined in the EF-HDI definition of sustainability. This capability therefore describes the extent to which the built environment supports required performance levels in areas such as ‘Education’, ’Health’ and ‘Quality of Life’.

Built Environment Sustainability Capability
Built Environment Sustainability Capability is a combination of EF and HD capability and provides an overall measure of the extent to which the built environment of an area supports sustainability.  Ecological Footprint Capability, Human Development Capability and Built Environment Sustainability Capability is measured in the Built Environment Sustainability Tool (BEST) and presented in figures and graphically in reports such as the one shown below.
