5 Facts about urbanization in Africa

5 Facts about Urbanization in Africa and arising Threats and Opportunities.

Rapid Urbanization:

More than half of Africa’s population will live in its cities by 2040. This translates into a population growth of more than 40,000 new urban inhabitants per day between now and 2040.

With an exception of Seychelles, 71% of urban population in sub-saharan Africa live in slums. In his 2014 World Habitat Day Speech, Seychelles Land Use and Housing minister Christian Lionnet said,

““In Seychelles, since the early years after independence, the government has adopted a pragmatic and consistent approach to housing development based on strong socialist principles. Special vigour has been put on long term programmes for appropriate solution in tackling our housing shortages.  The government has remained focus on its aim to reach a position where the laws of supply and demand come into play fairly.  Today, over thirty years down the line, Seychelles’ ultimate aim for housing is not only to facilitate access, but for every Seychellois to own his or her house.Figures from the last Population and Housing Census (2010) reveal that in 2010, 71% of families in Seychelles own the houses they are living in. This make Seychelles ranked among the top countries in the world on par with the developed nations.”

 

71% of the population in Seychelles own their homes. Over 450 million new urban dwellers are expected between 2010 and 2040, with half of Africa’s population living in urban areas by 2040. This presents various Threats and Opportunities depending on the level of preparedness of Cities.

In Nairobi, between 1971 and 1995, the percentage of the urban population living in slums almost doubled to 60%

Cities are Engines of Economic Growth and in that sense, must prepare to take centre stage of Rapid Urbanization. There are three main enablers to enable Cities generate economies of scale advantages. Urbanization alone is not sufficient to regenerate the Cities of Tomorrow. They also require:

 

1. Public investment in infrastructure. There is need to reform policy and legal framework for better integration of city planning and management.
2. Enterprise investment in productive capital. Enable businesses to create quality jobs for people moving into urban areas. This will enhance the ‘Working Environment.”
3. Household/private investment in housing. Strengthen institutions and systems that make cities competitive and sustainable. This will enhance the ‘Living Environment.”

 

If people have opportunities for income, work productivity, opportunity for recreation and socialization with quality housing and access to both the Work Environment and Living Environment, Urbanization is a welcome.

 

This is an opportunity for entrepreneurs and the Government. Apart from attracting productive capital, cities attract and galvanize entrepreneurs. Studies show that 80% of global economic activity is generated in cities; activities that benefit from density and proximity—of goods, people and ideas.

 

 Infrastructure Investment Lesson from China:

According to the World Bank, In 1980, the urbanization rate in East Asia was similar to that of South Asia and Sub-Saharan Africa. Between 1980 and 2010, the rate of urbanization doubled in East Asia to 50 percent, and the urban poverty rate decreased from 24.4 percent to 4.3 percent.5 By contrast, in Sub-Saharan Africa, where the urbanization rate increased from 23 percent in 1970 to 37 percent in 2011, urban poverty decreased only marginally from 41.5 percent to 33.6 percent.

 

If Rapid urbanization is well managed, it can curb urban sprawl, deteriorating access to services, greater inequality, and increased crime.

 

Boost Capital Investment:

China boosted its capital investment (including infrastructure, housing, and office buildings) from 35 percent of GDP in 1980 to 48 percent in 2011, while seeing a dramatic increase in urban population from 18 percent in 1978 to 52 percent in 2012. In contrast, capital investment in Africa has remained around 20 percent of GDP for over 40 years. China’s transformation was led by its cities, aggressively boosting investment and job creation by attracting low-skilled manufacturing industries that benefited from economies of scale and access to markets.

 

Informal or unplanned and under-serviced settlements are a common feature of many cities.In many cities, increasingly high levels of congestion, pollution, illness, disease, crime and insecurity add a huge burden to the economy through lost time and opportunity.

 

Inadequate Infrastructure is a Threat:

  1. Inadequate sanitation infrastructure in Africa’s urban areas is costing the economy around US$5.5 billion every year amounting to between 1% and 2.5% of GDP.
  2. 70 percent of Africa’s urban population lives in informal settlements and 60 percent of total urban employment is in the informal economy
  3. Countries with more than 60% of their population living in urban areas are expected to achieve 50% more MDGs on average than those with urbanization rates of 40 percent or less.
  4.  In the next 20 years, cities in the developing world will triple their built-up area (from 200,000 to 600,000 square kilometers) and double their population (from 2 to 4 billion). What will happen in Africa if we continue to under-invest in Infrastructure?

Housing as a Verb: The Sense In Building Slowly.

By definition, a verb is an action word. It brings the sense of unfolding series of steps. I would like to borrow this language and relate it to housing.
All the conversation around home ownership has primarily been around buying a fixed product. A House (A Noun). With no action expected on the part of the home owner apart from signing that mortgage agreement or cheque. This top-down authoritarian approach to housing ignores a major player in the equation, the user.
Intellectual Basis: The Freedom to Build
Most buildings cannot be occupied until they are finished. In real life, occupation certificate cannot be issued until the whole building has achieved Practical Completion. However, the question then to ask is, “What is “Completion?”, Can Practical Completion be Achieved In Stages?”

518gfvtmuml-_sx334_bo1204203200_“If housing is treated as a verbal entity, rather than a manufactured and packaged product (noun), decision-making power must, of necessity, remain in the hands of the users themselves.
The ideal we should strive for is a model which conceives housing as an activity in which the users-as a matter of economic, social, and psychological Common Sense-are the principal actors.  This is not to say that every family should build its own house, as the urban squatters do, but rather that households should be free to choose their own housing, to build or direct its construction if they wish, and to use or manage it in their own ways.” – Freedom to Build, John F C Turner & Robert Fitchter (1972)

 

Self-build and The Law
What does the law say about self-build? Is Owner-Building prohibited by the Law? Surprisingly, the answer is partly Yes and No. The National Construction Authority Act 2011 provides in Section 16:

“a person shall not be deemed to be a contractor if the work undertaken— (i) does not incur a cost exceeding such sum or sums as the Board may from time to time determine; or (ii) consists of a residential house for private use, not requiring a structural design.” – See more here.

 

• How many people can afford a Building Contractor?
• How many people can afford to buy a ready built house (ready to occupy)?
• Most importantly, how many people can afford a housing mortgage today?  According to a 2015 survey by Kenya Bankers Association, those who could afford a mortgage in Kenya are only 2.4% of the population.
For a majority of the population, Assisted Self-Build(ASB) (Also called Do-It-Yourself) is the only viable option out if the dream of Home Ownership is to become a reality. In this regard, Building Slowly is the Common Sense Solution!

The Reality
Admit it! Most people don’t have to have all the money to build their own “dream” house. And this is perfectly OK if you understand where to put the brakes and how to proceed to completion.
Nobody ever has enough of everything on short notice. That is why humanity has embraced the concept of growth. Countries aspire to be developed or middle-income after certain number of years. They tell us, “Rome was not built in a day,” but seldom do we hear stories of victory by ordinary people building their life one step at a time. We are inundated with messages of “Utahama Lini” as if housing is an emergency. It is not unless it is!
Real Life Example: Application of Build Slowly
In February 2010, a magnitude 8.8 earthquake hit Chile, killing approximately 500 people and destroying 80% of the buildings in the town of Constitución.

An award winning firm of Architects called Elemental reconstructed the homes named, “Villa Verde”, housing complex with more than 480 sustainable homes for the victims of the earthquake.

According to 99% Invisible, As part of the relief effort, an architecture firm called Elemental was hired to create a master plan for the city, which included new housing for people displaced in the disaster. Elemental built for the people Half-a-House with one half of the house ready to be moved in and the other half, just a frame with an empty space ready to be built up when the owner grows wealthy.

This is exactly the idea of a House as a Verb!

As you prosper, then you can have Add-Ons to the initial fabric or structure of the house. In this case, the house is never seen as a complete project but an unfolding expression of the ways, means and creativity of the owner.

If we can start looking at housing from this perspective, all the pressure that one must build NOW and Occupy the Entire House immediately, evaporates.
The technical term for this is called Site and Services Schemes or Incremental Building.
Advantages of Incremental Building:

  • Improvement and Modernisation of the units can be done at a later stage.
  • The fabric of the house can evolve to reflect the achievements of the owner.
  • As the expert, the Design-Build contractor can transform into providing affordable housing solutions or a series of Packaged Deals which any would-be home owner can pick and assemble incrementally with Add Ons as their fortunes improve. This is housing as it should be.

Are we looking at a New Opportunity of User-Controlled Housing?
Does it have potential to become the new vehicle of personal, family and social growth?

If we think of Housing as a Verb, we allow the People to Shape their Destiny. This way, we can build a better future together. …..to be Continued.
