World Bank, Development Delusion and Other Interesting Articles

Just read a great and informative article about the World Bank entitled “The World Banks Development Delusion”. The article briefly explores the history of the Bank and argues the need for change in the funding approach used by the World Bank, in its attempts to facilitate development and reduce poverty. The article made the following interesting points:

  • History shows that most of the countries that have come under the sway of the World Bank – and its sister institution, the IMF – have experienced declining development outcomes over the past 30 years or so.
  • Developing countries need much more control over decisions that affect them. Power in the World Bank is presently apportioned according to members’ shares, just like in a corporation. Major decisions require 85% of the vote, and the United States, which holds about 16% of the shares (and controls the presidency), wields de facto veto power. The same is true of the IMF. Developing countries together hold less than 50% of the vote, which is shocking given that the institution supposedly exists to promote their welfare. • Development aid should be delinked from corporate bonds. This would take Wall Street’s interests out of the equation, eliminate the pressure to siphon wealth from debtors, and allow the bank to evaluate its performance on the basis of poverty reduction outcomes instead of loan volume, as is the current practice. (http://www.thoughtleader.co.za/jasonhickel/2012/09/28/the-world-bank-and-the-development-delusion/)

The article also reminded me about the poem The Development Set. Yes, I know I always mention this but it’s only because it’s so true and I have yet to see any real evidence of development finance institutions trying to steer away from being tarred by the same brush that tarred “The Development Set”.

Water Scarcity And Your Virtual Water Consumption ?!

A renewable resource is a natural resource with the ability to reproduce through biological or natural processes and replenished with the passage of time. Renewable resources are part of our natural environment and form our eco-system. One such resource is water. Water is able to regenerate and is part of our natural environment. However water may only be considered a renewable resource when carefully controlled usage, treatment, and release are followed.  (www.en.wikipedia.org, 2012)

UN research indicates that we are facing a serious water scarcity problem.

  • Approximately 700 million people in 43 countries suffer as a result of water scarcity.
  • By 2025, 1.8 billion people will be living in countries or regions with absolute water scarcity, and two-thirds of the world’s population could be living under water stressed conditions.
  • With the existing climate change scenario, almost half the world’s population will be living in areas of high water stress by 2030, including between 75 million and 250 million people in Africa. In addition, water scarcity in some arid and semi-arid places will displace between 24 million and 700 million people.
  • Sub-Saharan Africa has the largest number of water-stressed countries of any region

(www.un.org/waterforlifedecade/scarcity.shtml)

So if water is meant to be renewable why are we in this problem?

The reality is that water in our current societal context is not really renewable because we have compromised the ability of the water resources to regenerate.  Water affects all of us all the time and in every way possible. For the purposes of readers (assuming that most readers/ people with access to the internet of this post have easy and regular access to potable and piped water); water scarcity doesn’t just impact on how many baths or showers we take or how often we flush the toilet or whether we drink bottled or tap water or if you have a low flow shower head etc

Water is an integral and critical component of the environment and is therefore fundamentally important for the survival of humankind and society as we know it (not meaning to be alarmist…. but it is true).

“Water is one of the primary barometers of climate change: A rise in sea-levels, flooding, and extreme storms combined with general water stress and more severe and frequent droughts will escalate crises in municipal infrastructure, requiring continual upgrades for water purification, stormwater drainage, and sewage treatment, all of which will dramatically raise the price of water at the retail level. ( Bond, 2011) 

It has been predicted by the Water Resources Group that the global demand for water will outstrip supply by 40% by 2030 (CDP, 2011), this indicates that something is very wrong with the way that we are using our water resource considering the fact that water, despite being a finite resource is a renewable resource.  Water use has increased exponentially and has been driven by increasing water demand from industrialization, economic development and population growth. This has resulted in increasing competition for our water resources, which has resulted in increased tensions and challenges around the management, allocation and sustainable use of water resources.

In many instances the water needs of large-scale agriculture and industry end up competing for the water that essential for the sustaining local communities and ecosystems. Ecosystems are an essential component of the hydrological cycle as they are not only reliant on water for survival but also provide a key role in water purification and provision, thus ecosystems maybe seen as nature’s natural “green” infrastructure and service providers.  In addition ecosystems also provide us with the very important ability to adapt to climate change impacts and environmental degradation. It is therefore obvious that we need healthy and functioning ecosystems in order to ensure that we have a sustainable water source.

We all know that we need water to survive however the fact that water contributes in some way to the production and use of everything we consume and use is often overlooked. Everything that forms part of our lifestyle and society has a virtual water value. Virtual water refers, in the context of trade, to the water used in the production of a good or service (www.en.wikipedia.org, 2012). It should however be noted that specific measure of virtual water can be more or less depending on regional context, climatic conditions and agricultural practice. The virtual-water content of a product, commodity, good or service may be defined as the volume of freshwater used to produce the product, measured at the place where the product was actually produced”. (www.en.wikipedia.org, 2012). This definition is important as many of the goods and service produced in water poor areas are consumed in water rich areas, resulting in the true water value not being fully considered or accounted for by the consumers.

For example, a liter of potable water in “water-rich” Scandinavia is unlikely to be as precious/valuable as a liter of potable water in water-scarce Namibia (CDP 2011). Consequently the 70 liters of water it takes to make 100 grams of apple may have more value in Namibia than it does in Scandinavia. This combined with the fact that a large proportion of the food you eat, the clothes you wear and the goods and services that you consume often not produced locally increased the virtual water value of the product.

An example of this would be 100% organic cotton t-shirt has a virtual water value 2700 liters! The 2700 liters mean a great deal more to someone living in an arid environment and having to draw water from a communal well than it does for someone living an a water rich area who has access to piped potable water.

Examples of virtual water values are:

  • 2400 liters of water to make 100 grams of chocolate.
  • 70 liters of water to make 100 grams of apple
  • 5000 liters of water to make 500 grams of paper
  • 2499 liters of water to make 150 grams of burger
  • 4650 liters of water to make 300 grams of beef (about one steak)

(www.virtualwater.eu)

Our economy and society are dependent on water and the virtual water associated with the production of goods and services. If the cost of water went up so would the cost of all our goods and services. How we use and pollute our water is therefore a critical issue especially since the amount of water that is clean and drinkable is steadily decreasing due to pollution (UNEP WHO 2012) arising from our unsustainable use of water and the inability of ecosystems to effectively purify water due to environmental degradation.

In the UK, for example, “it has been estimated that two-thirds of all the water that its population of 60 million people consume actually comes embedded within the imported food they eat, the clothes they wear and industrial or chemical goods they purchase. The result is that local water management issues affecting disadvantaged communities around the world may be significantly exacerbated and influenced by consumption patterns in more affluent countries.(CDP 2011)

How are we, a society that is entirely dependent on water, who’s wasteful and inefficient use is the reason we are in this problem meant to respond to the water resource challenges? Especially as the water problem will undoubtedly result in associated environmental, economic, political and social problems?

Simply stated we need to change the manner in which we consume and produce goods and services. As consumers we need to question and refuse to consume products and services with high virtual water values. Also we need to recognize that not everything is a necessity and we can do without some/ a great many of the extras and luxuries that we consume.

We can’t change our habits overnight (though it would be great if we did….), instead we need to make a difference where we can and build up to making the big changes that we need to make in our consumption and production patterns.

A few pointers to help you reduce your water and virtual water consumption:

Water reduction tips for dummies:

  • Shorter bath and shower time
  • Close tap while brushing teeth
  • Recycle water in the home.
  • Plant indigenous plants in your garden
  • Check and fix any leaks in your home

 Virtual water reduction tips for dummies:

  • Buy local and seasonal produce grow your own veggies
  • Eat less meat: become vegetarian, meatless Mondays etc
  • Eat less chocolate …(difficult I know….)
  • Waste less
  • Reuse and recycle organic products like paper, cotton etc
  • Don’t be a slave to fashion: Buy good quality and timeless clothing that can take you from season to season reducing the need to keep replacing your clothes etc
  • Download a virtual water application to help you make smarter choices.

RIO + 20: Worth The Effort ?

Rio+20 is upon us and I haven’t posted or put any real thought or effort into the Rio+20 excitement, despite the Rio + 20 summit being hailed as  a “wonderful, green and strategic” decision making moment for the world! Does this make me a bad “greenie” or put me in the box with people who don’t care about the planet or nature or the green economy or pandas….?

I can assure you that I am very concerned about the development path/ economic trajectory that we are on. This despite the assurances and re-assurance from multinationals, corporates and governments that;

  • sustainability and equity issues are being mainstreamed
  • business and government are working towards solutions for the pressing issues of sustainable and equitable development
  • We are in fact slowly transitioning to a greener economy

“Rome was not built-in a day” but how many more summits, conferences, COPs, protocols, accords agreements,laws etc do we need before we are able to see any real and tangible sustainable development?  The fact that these conferences and summits etc attract some of the worlds greatest development minds, authorities and governments that meet (over and over again) to try to sort out the various development challenges that we face should indicate that the processes that we use to address these development challenges may not be working? maybe it is time for something else?

This week, up to 100,000 people are streaming into Rio de Janeiro for the year’s biggest international event – the UN Conference on Sustainable Development to be held on 13-22 June. (M Khor)

With this in mind lets look at the a few issues that should be but will in all likelihood not be fully or adequately addressed or resolved at Rio+20;

  • Fossil fuel subsidies: do we really need to subsidise one the key things that is responsible for a great many of our environmental problems?
  • Emissions targets: who gets which piece of the pie?
  • Tipping points and pollution and the degradation of natural resources and landscapes: It is a well-known fact that we have to stop and redress  the pollution and degradation.
  • Equity and access to natural resources: Define fair, access and resource?
  • Green Economy: what is the definition? is this the silver bullet/ solution? or do we need something else
  • Food and resource security and scarcity: overconsumption, in efficient production methods etc
  • Full informed participation of affected stakeholders: better community participation: is it only government and business that know what is good for the rest of us?

What I am basically saying is that assurances of governments, the champagne environmentalists, the green-bling-brigade, the development set etc I am still not convinced that we are achieving much development impact by hosting  summits, sitting around and arguing the format of draft agreements and accords.

While I will keep my fingers (and toes) crossed for some exciting decsions and actions resulting from RIO+20, I will not hold my breath or drop what I am doing to follow the developments of the summit. We need to see action and change, not more meetings about meetings etc ….

Infrastructure vs Appropriate/ Effective/ Sustainable Infrastrucutre ?

The Three Gorges Dam in China

“There can be no prosperity without infrastructure, but infrastructure projects don’t necessarily benefit the poor. Past energy, water and transport strategies have neglected the poorest population groups, and taken a heavy toll on affected people and the environment. Will the new infrastructure strategies of the World Bank and the Group of 20 address the needs of the poor, or will they entrench the power of privileged groups?” (IRN, 2012)

Infrastructure is perceived as being a key driver behind economic growth, development and job creation. It is argued that the development of infrastructure projects, particularly large infrastructure projects and dams, will act as a catalyst to:

  • Open up areas that are not currently developed to development
  • Enable service provision to those who lack basic services
  • Create jobs
  • Facilitate economic development.

With this in mind many governments, development finance institutions and business development agencies are backing the Group of 20, the World Bank and other multilateral development banks (MDBs) new strategies for infrastructure development. “In November 2011, the Group of 20, the World Bank proposed to focus public support on strategic regional infrastructure projects such as large dams and transport corridors, and to make them attractive for private investment through public guarantees and other incentives (International Rivers Network, 2012). The group argue that centralized infrastructure projects which include private participation in public sector projects will lower the costs of services and service provision particularly in rural areas.  In so doing the public sector will be able to meet its infrastructure and service provision mandates with private sector seen to be assisting in this basic service delivery while also ensuring that the private sector is able to ensure economic development and growth. In other words a win-win solution to the world’s (sustainable) development problems that makes both the public and private sector look good.

It is however interesting to note that despite many such “win-win” public private large-scale and mega infrastructure projects being implemented we are still quite far from either sustainable service delivery or sustainable development. This is primarily because in most instances it is the private sector that benefits to the detriment of the public sector and local communities that are associated and usually impacted by such large infrastructure projects.

The development landscape is littered with failed and costly infrastructure projects that have promised but not always delivered services, growth and (sustainable) development. This is reiterated by the MDG and other development targets which are consistently not being met despite funding being directed specifically at meeting the targets. Especially considering the fact that “Economic infrastructure – essentially, transport, energy, information and communications technology, water, sanitation and irrigation – is specifically identified in the MDGs”(UN Habitat 2011).

Some interesting points related to development projects not realizing the proposed development impact;

  • The World Bank Group (2011) has also stated that its bias towards “infrastructure investments that promote growth, with expected ‘trickle-down effects have yielded very little “trickle down”.
  • Evidence available indicates that the poor are often the last to benefit from increased access (from road infrastructure). In most countries, the rural poor tend to be overlooked because private operators are reluctant to serve low-income clients given that these markets are not financially viable on a freestanding basis. (World Bank Group, 2009)
  • Despite the issues surrounding the Bujagali Dam the Ugandan government began building the Bujagali dam on the River Nile in 2007. The project had previously been delayed for over ten years for many reasons, including exorbitant project costs and its predicted economic and environmental impacts. Impacts associated with the dam included the destruction of the Bujagali Falls on the Nile, livelihoods impacts to about 6,800 people. In addition the dam will affect the performance of other dams on the river Nile, and increase Uganda’s carbon footprint. (FOEI, 2009). The project is financed by the World Bank the African Development Bank and the European Investment Bank (EIB) and it has been suggested that both the banks and the Ugandan government have overlooked and even ignored their own safeguard policies. (IRN, 2002).
  • Dams have made an important and significant contribution to human development, and the benefits derived from them have been considerable. In too many cases, an unacceptable and often unnecessary price has been paid to secure those benefits, especially in social and environmental terms, by people displaced, by communities downstream, by taxpayers and by the natural environment.” (World Commission on Dams, 2000)
  • The President of the Pakistan Network for Rivers, Dams and People (PNRDP), said in a statement that “it had been proved that the project executing agencies lacked capacity to deliver in terms of time and cost and had failed in resettling hundreds of thousands of people displaced due to these projects”.

 So why the continued focus/ bias on large infrastructure projects? especially as there is more and more evidence that smaller contextualized infrastructure solutions are more sustainable, cost-effective and appropriate. It should also be noted that the need for infrastructure, development and service provision that is sustainable, cost-effective and appropriate is made even more pressing by the climate change, environmental degradation and economic crises that we are currently experiencing.

The above graphic clearly highlights and contrasts the development impact of a large infrastructure solution for energy provision against a cheaper smaller infrastructure solution for energy provision. It is evident that smaller context specific infrastructure provision is not only cheaper but more appropriate and less environmentally damaging.

Millenium Development Goals: Time for a Rethink?

In September 2000 United Nations member countries agreed on eight goals aimed at encouraging development by improving social and economic conditions in the world’s poorest countries. These goals were adopted in the United Nations Millennium Declaration and are known as the Millennium Development Goals (MDGs).

In addition to the above aims, the MDGs’ intend to provide a framework for the entire international community to work towards a common goal focused on human development, poverty reduction and increased opportunity to access and benefit from global economy. The goals are as follows:

  • Goal 1: Eradicate Extreme Hunger and Poverty
  • Goal 2: Achieve Universal Primary Education
  • Goal 3: Promote Gender Equality and Empower Women
  • Goal 4: Reduce Child Mortality
  • Goal 5: Improve Maternal Health
  • Goal 6: Combat HIV/AIDS, Malaria and other diseases
  • Goal 7: Ensure Environmental Sustainability
  • Goal 8: Develop a Global Partnership for Development with developing countries, develop and implement strategies for decent and productive work for youth

As the target date (2015) for achieving the targets set for the MDG’s looms there is much debate on the success of the MDGs, whether they should be reviewed, re-defined or completely replaced.

According to a CESR article the first decade of progress against the MDGs revealed “the inadequacy of the international community’s efforts to meet commitments made a decade ago to fight poverty and other forms of deprivation such as hunger, disease and gender inequality.” In addition the 2011 UN report on the progress against the MDGs also revealed that between 2000-2010 progress against the MDGs’ had been inequitable and has in most instances bypassed the poorest, most vulnerable and disadvantaged sectors of the population who are meant to be the key beneficiaries of the MDGs’.

Thus it is evident that the MDGs despite being well-intentioned and aimed at facilitating human development have not necessarily hit their mark. There are various reasons and debates in relation to the success or failure of the MDGs. However, in my opinion the key issues requiring revision, re-thinking or attention are as follows;

1. The fact that the MDG targets are set for the world as a whole. An impact of looking at the MDGs as global targets is the fact that the development needs of specific countries and regions may be over looked. This is highlighted by the following UNDP statement;

“While the share of poor people is declining, the absolute number of the poor in South Asia and in sub-Saharan Africa is increasing.” (http://www.undp.ro/mdg/basic_facts) 

In other words: There is a significant need for locally defined MDG targets and not broad “world” based targets.

2. The MDGs’ are focused primarily on achieving targets as opposed to the process required to achieve the required development impact. This may be seen as limiting the scope of and reducing the impact of the development efforts. In other words: the “how” is just as important as the “what should be!”  Consequently, issues such as local needs and capacity should have been more effectively considered and integrated into the goal setting process.

3. The focus on numerical targets. Such targets are difficult to measure within the context of many of the less developed countries, which lack reliable data and the institutional and government capacity to collect and measure such data. Numerical targets do not always guarantee effectiveness or development impact.

“The problem of incomplete data has been recognized in Africa where most people are said to die or be born “without leaving a trace in any legal record or official statistics. In rural Africa, there are few hospitals, home births are common and assistance from a midwife or another health official rare.” (Katie Nguyen, Reuters Alert Net)

4. Aid does not necessarily result in development. The MDGs’ in many instances had the effect of focusing international aid flows specifically towards the attainment of MDGs’. This was based on the presumption that the MDGs’ are the optimal way of ensuring development and poverty alleviation. However, in certain instances this had the effect of misdirecting aid away from the real development issues within specific and local country contexts.

This sentiment is highlighted by Archbishop N Ndungane, as follows;

delivery on aid commitments have recorded a steady increase from 2004 through 2009. While it is a positive trend, it has created a tendency to focus more on aid in terms of the resources needed for the realisation of the MDGs than on the other sources. The recent global crises have come as a rude shock to remind us that this was a distortion and huge mistake”

The sentiment is also reiterated by the site; Globalissues, as follows;

“aid has often come with a price of its own for the developing nations:

  • Aid is often wasted on conditions that the recipient must use overpriced goods and services from donor countries
  • Most aid does not actually go to the poorest who would need it the most
  • Aid amounts are dwarfed by rich country protectionism that denies market 
access for poor country products, while rich nations use aid as a lever to 
open poor country markets to their products
  • Large projects or massive grand strategies often fail to help the vulnerable 
as money can often be embezzled away. 
It is time for these countries in need of development to call for justice and for the countries that once promised to help the world to actually fulfill their promises.” (http://www.globalissues.org)

These issues highlight the need to rethink the manner in which “development” and aid should be considered when the MDGs’ goals are assessed for impact and a post- MDGs’ framework or path is forged.

A continued focus on financial aid and development that does not effectively, equitably and sustainably consider local and regional contexts, capacities, needs and sensitivities will not only be a waste of resources both financial and natural, but also a waste of time. We need to prevent any further misdirected efforts especially within the context of increasing resource degradation, climate change and environmental vulnerability.

Some Thoughts on Green Buildings & Sustainable Development

Image

Something to think about and some ideas that you could use next time you play simcity or make very important decisions about how the planets resources are used!

 

 As a society we are dependent on our built environment and our natural environment. It is evident that the built environment has significant impacts on our natural environment and the health of our society. It therefore makes perfect sense to ensure that our built environment does not negatively affect the sustainability of our society and nature. The built environment is a significant contributor to Green House Gas (GHG) emissions and influences the manner in which we as a society utilize our resources. There is also proof that green buildings promote the health and productivity of the buildings’ inhabitants and uses.Consequently we need to ensure that our built environment reduces and minimized GHG emissions and also facilitates the sustainable use of our resources.

“… green buildings typically cost up to 5 percent more than standard buildings during construction, but can reduce waste output by 70 percent, water usage by 40 percent and energy usage by 30 to 50 percent.” (www.worldgbc.org)

Thus it makes perfect sense for all new buildings to be green. However, the concept of green building and the green building sector have been around for quite a while and don’t seem to have made much of an impact on the built environment landscape. 

 Image

How many of the buildings that you use/ see every day may be categorized as green buildings that are contributing to the sustainability of the planet and society?

 “Green buildings represent 2 percent of the commercial buildings and 0.3 percent of new homes in the US.” (http://www.scientificamerican.com/article.cfm?id=green-buildings-may-be-cheapest-way-to-slow-global-warming)

 The concept of green buildings and the greening of the construction and building is a dynamic and evolving debate that covers (and brings together) a plethora of stakeholders, professions and topics. This in my opinion is the reason that the green building sector hasn’t moved beyond building certification, passing of (some) legislation and the development of a few green buildings that may or may not be facilitating the establishment of a sustainable society. It is evident that green building could in fact contribute to sustainable development; however, there are a few barriers that need to be overcome before the green building sector is able make a more sustainable development impact. The key issue in this regard relates to the skills and stakeholders involved.

In order for the green buildings sector to be able to make a more effective development impact and contribute successfully towards sustainable development the following should be considered;

  • Fast tracking of the creation of an enabling environment. This includes policy frameworks, legislation and regulation through increased public sector involvement. This would create a demand for green buildings and greening technologies as well as create incentives and tax benefits.
  • Broadening of the skills set in the construction sector and the use of multidisciplinary teamsthat do not only include the standard construction industry type of skills.
    • The members of these teams need to be able to effectively work and communicate across professions.  
    • Team work, coordination and leadership skills are core skills in green building (www.uncsd2012.org)
    • Increased awareness and capacity building initiatives that include non- construction sector stakeholders. This would;
      • Ensure that people understand why it is important to build green buildings
      • Show the public that there is another way of building
      • Highlight the cost and health benefits of green buildings.
      • Increase the demand for green buildings.
      • The need to move away from an energy efficiency focus in green buildings towards a more sustainable development focus. There needs to be a more integrated approach that goes beyond energy, emissions, heating, cooling and solar panels etc Waste, transport costs, water and biodiversity should be integrated into the planning and build process.
      • A move away from green buildings being seen as primarily large scale developments to a broader focus which includes green buildings within the residential sector. This would also have the effect of making green buildings accessible to a larger portion of the population.
      • A move away from a tick box approach to green buildings towards an increased focus on the actual performance of the building.
      • Green buildings need to be contextualized within a broader development and planning framework. Of particular importance is the need to focus less on individual green buildings and increase the focus on green developments which incorporate and integrate green buildings and green design.
        • A green building that is inaccessible would negate the benefits of being green if it is associated with high travel costs and travel related GHG emissions.
        • A green building that provides bicycle parking yet is located in area that is not conducive to bicycle use is a waste of bicycle parking space.   
        • Green buildings need to be integrated into the service provision and infrastructure needs of the surrounding environment. A green building that doesn’t contribute to the sustainability of the area that it is situated in is not really that sustainable or green.
        • Green buildings could be used to provide services to the surrounding area. Examples are
          • A building that generates excess electricity (solar, wind, biogas etc) that is then feed into the grid.
          • A building that harvests rain water that can be used to water parks or gardens in proximity.
          • Rooftop gardens that provide green spaces or act as green lungs in dense urban areas.  
          • Rooftop gardens that provide food to surrounding areas
          • etc

Role of Sustainable Transport in the Creation of Sustainable Cities

Image

Cities, especially African cities are facing increasing challenges in terms of resource scarcity, climate change, rural urban-migration, environmental degradation and disaster mitigation. Urbanisation and the growth of cities is increasingly placing pressure on land, energy and resources resulting in increased environmental threats and vulnerabilities and it is estimated that two thirds of the world’s population will be living in cities by 2030. 

The transport system of a city is an effective reflection of the quality of life, the range and location of activities and the range and availability of goods and services within a city. Thus it is evident that transportation and transport systems are integral to the effective and equitable functioning of a city. The significance of the role of transportation within a city is further reiterated by the following:

  • Approximately 20-30 percent of a city’s land-use budget is used for transportation infrastructure and to facilitate transportation (Mathew and Rao, 2006).
  • According to the South African Ministry of Science and Technology (2011) the transport sector accounts for 30% of the country’s GHG emissions and is therefore considered a major GHG contributor.
  • Transportation has the ability to integrate as well as isolate cities and societies.
  • Globally automotive CO2 emissions are increasing steadily (IEE, 2009).
  • Globally transport is the second highest CO2 emitting sector with emissions being estimated to reach 18 billion tones by 2050 (IEE, 2009).

Transportation plays a key and critical role in the functioning of cities and is therefore able to play a fundamental and strategic role in the future of our cities. In particular, city’s transportation systems are able to play a significant role in reducing GHG emissions and facilitating resource use that is efficient, equitable and sustainable. Key factors impacting the manner in which a city utilizes resources are land use densities, primary activities and energy and transportation efficiencies. These issues are directly linked to the manner in which the city has developed, is planned and how the city will be planned and developed in the future.

In order to facilitate more sustainable transportation and ultimately sustainable cities the key sustainable transport characteristics that  should be incorporated into city planning are as follows:

  • Cities should be planned to be inclusive, to facilitate accessibility and be equitable.
  • Cities should be planned with pedestrian and cyclist accessibility and movement as the priority.
  • Cycling and other non-green house gas emitting modes of transport should be prioritized above motorized and other green house gas emitting modes of transport.
  • Pavements and cycling lanes should be planned for and integrated into all new development applications.
  • Pedestrian and cycling facilities should be linked to public transport networks.
  • Public transport should be prioritized over individual car based transportation. In this regard linkages to stations and bus routes must be planned, integrated and effectively implemented with the aim of promoting public transport use above individual car based transportation.
  • Transport systems should be tailored to the size, form and key functions of the city with the aim of providing a balanced transport system.

Water and Ecosystem Infrastructure

(After the previos post about Waterless Jeans I though it a good idea to provide some context of the issue of water and water as a resource etc.. so here goes!)

Demand on Water Resources (Undited Nations Population Division)

A few facts related to Water and Ecosystem Infrastructure.

  • 75% of our natural resources are over utilized. This has far reaching impacts for our ecosystems and economies. An example is the Aral Sea. Aral Sea was 4thlargest fresh water system.
    • It is 10% of its original size.
    • Pollution and over utilization of the water yield of the lake has resulted in the Aral Sea no longer being able to provide Ecosystem Services such as water and fish and resulting in economic hardship and unemployment
    • Approximately 60 000 fishermen have lost their jobs.  
    • 50% of South Africa’s water extractions come from surface water resources such as lakes, rivers and dams. This has significant implications for the development of the country, the health of water resources as well as water users.

Aral Sea: not much water left.

Ecosystem Infrastructure refers to the services that are provided by natural ecosystems. These ecosystem services include servicessuch as water purification; flood control, recreational amenities, and climate stabilization. Ecosystem services may be considered as “free” services provided by nature and are particularly important when looked at within the context of services that support economic and social development.

Linkages between ecosystem services and human well being (www.maps.grida.no)

I recently attended a presentation on the importance of ensuring integrated planning the provision of water services. The presentation linked water as a natural resource critical for economic and social development with the importance of ecosystem infrastructure such as watersheds. An example of ecosystem infrastructure in water service provision would be the financial cost savings that are possible through the effective development and management of dams and watersheds in relation to dam siltation.

  • The siltation of a dam involves the gradual build up of silt behind the dam wall. Siltation often negatively affects the health and usefulness of a dam and results in a reduction of water yield from the dam.
  • The average cost of building a dam is (approximately) R20 per cubic meter of water stored.
  • The average cost of de-silitation is (approximately) R8 per cubic meter
  • If a watershed is managed in a sustainable manner the risks and costs posed by siltation of dams are preventable.
  • Thus it makes financial sense to prevent siltation through the management of the ecosystem infrastructure associated with water and dams. This can be done through watershed management and the management of land uses within watersheds.
  • Some examples of watershed management initiatives that increase water yielded and prevent erosion and therefore siltation are: alien clearing, sustainable land use practices, erosion prevention etc

The concluding message from the presentation was; it is essential to ensure that the integrity and health of our water resources and associated ecosystem infrastructure are maintained in order to enable sustainable development and a transition to a green economy. It is therefore fundamental to recognise ecosystem services and infrastructure as strategic and fundamental element of infrastructure development and service provision.

This also stresses that recognition that a key step towards incorporating ecosystem infrastructure into the infrastructure planning and development processes is required to facilitate and support sustained and healthy economic growth and a transition to a greener economy. In addition, the recognition of the strategic importance of ecosystem infrastructure in infrastructure provision and development planning is central to the debate surrounding the value of ecosystem services and elements. The value of such services and resources need to be looked at from an integrated point of view as opposed to merely being considered as resources to be exploited.

We need to change the manner in which we value and use our natural resources.
