Problems facing cities need new thinking, says UN-Habitat boss

In October last year Joan Clos, the 62-year-old, two-time mayor of Barcelona, Spain, became Executive Director of the United Nations Human Settlements Programme (UN-Habitat).

His predecessor, Dr Anna Tibaijuka of Tanzania, had long tried to impress on world leaders the need to reduce by half the number of people living in slums and squatter settlements by 2015, the target date for achieving the UN’s Millennium Development Goals.

It is an ambitious vision because the population of African cities is projected to more than triple over the next 40 years, according to a UN-Habitat report – The State of African Cities 2010.

Those who flock to the continent’s cities in search of work and a better life will continue to swell the already bursting slum populations. And while Habitat’s vision is to create a better urban future for all, there is no doubt Dr Clos has his job cut out for him.

The way he sees it, he has already had an opportunity to become familiar with urban development as a city councillor in the 1980s, mayor in the 1990s and as head of Metropolis, an international network of cities that specifically opened his eyes to the broader global perspectives of urbanisation.

Today, as a UN under-secretary-general, he hopes to develop, together with his team, new strategies for sustainable urbanisation.

Nairobi, the city that hosts his office, is home to a little over three million people, according to the 2009 census, and is projected to receive a million more by the end of the decade.

More than half the world’s population already lives in cities — nearly quintupling the number in the 1950s, according to The Global Report on Human Settlements 2011.

But the the fact remains that come the end of the day, the majority of city workers would rather trek back to their informal settlements than remain in rural areas trying to eke out a living from agriculture.

The allure of the city remains its shiny skyscrapers, better infrastructure and hope for a better tomorrow – even though today, residents face issues of inadequate water and food supply and poor, sometimes inaccessible, healthcare.

So why not develop the rural areas and stem this heavy influx to the cities? According to Dr Clos, that may not be the right solution.

“There is no evidence that we can create a prosperous rural area. In any case, we have no resources to make rural areas as good as the cities,” he said. “The more we entertain the myth of rural richness, the more we delay in getting the solutions for the city.”

The key to sustainable urbanisation, he believes, is for leaders to develop a positive urban policy.

“We should begin with aligning our psychological state of mind in order to stop viewing the city as a liability. We must begin to see the city as an asset for growth and development before we act.”

Dr Clos knows many things about urbanisation and the kind of action that could make it sustainable, however ambitious.

During his tenure as Barcelona mayor from 1997 to 2006, he implemented the design and preparation of the Barcelona@22 Project aimed at renovating the city’s industrial and technological zones.

He spearheaded the additional renovation of some 250 hectares of land in one of the city’s most deprived areas to create social housing, hotels and offices. His bold move earned him a number of awards including, a gold medal from the Royal Institute of British Architects for transforming the city.

And now the challenge he faces is to transform the world’s cities.

“My vision is to promote the rethinking of a city’s capability to be the engine of growth, prosperity and job creation,” he says.

Job creation, he says, is a priority issue for UN-Habitat. Through its youth fund, the agency provides grants of up to $25,000 (Sh2,075,000) every year, for new ideas and solutions for job creation, good governance, adequate shelter and secure tenure.

A graduate in medicine with qualifications and experience in public health administration, Dr Clos is not blind to the health, sanitation and security issues that compromise the benefits of rapid urbanisation.

As informal settlements become more and more congested, the reality of communicable diseases sets in. The fact that informal settlements in a good number of cities around the world make difficult quick access to public services is also worrying.

“Cities, not just in Kenya, have narrow inroads that may not allow for mobility or access by fire brigade vehicles, for example, should a need arise, and yet, there is a regulation prescribing the percentage of land allocated to streets,” he said.

With the continued global rapid rate of urbanisation, more competition over land and land-based resources like water are to be expected. The to-do list of Dr Clos and his team cannot but grow longer.

Designed to save Mother Earth - New UNEP HQs

Environmental conservation and the war against global warming are among the biggest responsibilities of governments today. Scientists have been working round the clock to design innovative ways to build eco-friendly cars, machines and, in the past few decades, buildings.

With statistics from the American Institute of Architects indicating that buildings account for an estimated 48 per cent of all greenhouse gas emissions, the United Nations and some governments and civil groups have been pushing for “green” features in the design of new buildings.

Unlike the concrete and glass boxes that need huge amounts of non-renewable resources to run, green buildings are designed to support rainwater harvesting, bicycle commuting, solar heating, natural ventilation, and many other environmentally friendly practices.

This, in turn, ensures that the structures emit fewer greenhouse gases, consume less energy, use less water, and offer their occupants healthier environments than those in typical buildings.

These innovations are meant to make urban development environmentally sustainable and user friendly. To walk the talk, the United Nations’ Nairobi office launched one of the most eco-friendly structures ever built in the Kenya, and probably Africa.

Housing the headquarters of both the United Nations Environment Programme (Unep) and the United Nations Human Settlements Programme (Habitat), the new structure is designed to reflect the two organisations’ mission statement — sustainable urban development.

With 6,000 square metres of solar panels, natural ventilation systems, and many other green features, the building is expected to be energy sufficient in a year’s time.

“The building sector is the single largest contributor to global greenhouse gas emissions, with one third of global energy use taking place in offices and homes,” explains Mr Achim Steiner, director-general of the United Nations Office at Nairobi.

“So the design and construction of new buildings — and the refitting of existing ones — represents one of the key, low cost ways of combatting climate change while reducing electricity bills and dependence on fossil fuels.”

The building is designed like a chimney, allowing warm air from the ground level to waft across the office areas before escaping through the sides of the vaulted roof. This guarantees cool temperatures in the offices without having to use air conditioners.

Besides the washrooms being served by harvested rain water and being fitted with water-saving taps and lavatories, waste water is treated in a state-of-the-art aeration facility nearby and then used to irrigate the interior compound landscaped with the country’s four ecosystems in mind — forest, savannah, desert, and coast.

Solar panels are expected to generate around 750,000 kilowatt hours a year and measures have been put in place to ensure that the complex attains energy neutrality — where all power used by the building and its occupants over the year is met by renewable sources.

“We are aiming to have the building energy neutral over the course of the year, not for it to be completely energy independent,” explains Mr Rob de Jong, one of the experts leading the efforts to maximise the energy sustainability of the building.

“There will be some days when the panels will produce more than we need and others where there may not be enough sun.”

One of the biggest electricity consumers in the office setup after lighting is the information technology department.

To take care of this, the designers incorporated an innovative data centre cooling system that uses air and water rather than electricity -driven fans. There is an electronic meter at the entrance reading the electricity generated and the carbon dioxide emissions.

The opening of the office complex, graced by UN secretary general Ban Ki-moon coincided with the release of a report by the National Environmental Management Board that classified Kenya as one of the most water-stressed countries in the world.

Green architecture gained currency in the wake of the 1973 energy crisis when the concept moved from research and development to reality as governments sought ways of cutting costs and reliance on fossil fuels. But due to the high initial costs of alternative energy, the number of people venturing into this technology was few.

However, over the years research has yielded more innovative and relatively cheap photovoltaic cells, which has made it possible for more building projects to use solar energy.

While Europe and Asia have embraced green architecture, the concept is yet to be fully embraced in sub-Saharan Africa, unlike in South Africa.

The most important factor in achieving green architecture in urban areas is strict legislation and regulation. The South African government has already called for a consideration of minimum energy efficiency levels when setting up new structures.

However, South Africa is far ahead of other states in the continent since it has an institution in charge of green building issues and a fully-fledged grading system.

The Green Building Council of South Africa (GBCSA) is in charge of green movements and has launched a rating system called the Green Star SA.

Among the major eco-friendly structures to be approved by GBCSA is the new Nedbank Phase II building in Sandton, Johannesburg, the 24 Richefond Circle in Umhlanga Rocks, and Villa Mall in Pretoria

While the green building concept is still in its infancy in Africa, Asia is set for an era of environmentally friendly construction boom in the commercial building sector, what with the many multinational companies striving to be named the most ecologically friendly and responsible organisations in Asia.

Besides the image value, many Asia-based companies are embracing green building due to substantial savings in terms of energy costs that these structures generate.

Asian countries experience warmer climates most of the year, which results in high electricity bills to run air conditioning, sometimes amounting to almost a third of the building’s total operating costs.

According to research conducted by CB Richard Ellis, a leading global property company, Asia accounts for almost 75 per cent of the total annual global office space construction.

This finding is underlined by the fact that the demand for architects, engineers, and design managers specialising in environmentally sustainable construction is on the rise in the continent.

The City Square Mall is Singapore’s first eco-friendly shopping complex. Completed in 2009, the 12-storey mall was awarded the country’s Building and Construction Authority’s Green Mark Platinum Award for innovative “green” features like eco-restrooms designed to save water and electricity.

The $200 million (Sh16.8 billion) building was also hailed for using environmentally-friendly materials such as drywall partitions, a non-chemical anti-termite system, designated parking lots for hybrid cars, and sensors to monitor levels of indoor carbon dioxide and carbon monoxide emissions.

Having invested five per cent of the building costs in installing the “green” features, the mall’s eco-friendly design is projected to cut energy usage by approximately 39 per cent, compared to designs using standard industry code.

Other benefits include saving an estimated 11 million kilowatts of electricity a year, reduction of 5,700 tonnes of carbon dioxide emissions annually — which would have required 25,000 trees to absorb — and saving an estimated $48,000 (Sh4 million) per annum in other expenses.

The biggest green project under construction now is the Freedom Tower at the site where the World Trade Centre once stood.

Branded the “Green Giant” and expected to be complete by 2013, the building will not only be the tallest in the world at 1,776 feet, but will also feature green enhancement concepts never tried in an urban structure before.

“It is going to stand out as a beacon to the rest of the world in pushing the environmentally friendly agenda,” explains Mr Guy Battle, president of sustainability consulting firm Battle McCarthy, that worked with the architects on the structure’s design.

At 1,200 feet above the building’s rooftop observation decks will stand a series of wind turbines that will generate up to 2.6 million kilowatts of electricity annually, which is 20 per cent of the building’s anticipated energy needs.

Placing the “wind farm” above the New York skyline is not only meant to expose the turbines to gushing winds, it also aims to display the wind energy enhancement technology to the city’s public.

“The long-term goal is to create carbon-negative buildings,” said Mr Battle. “Buildings consume half of all the energy in the world, but they should be giving back energy instead of only taking it”.

Apart from companies and organisations, there are individuals whose quest for green architecture deserves a mention.

When Bill Clinton was elected the US President in 1992, he announced a plan to make the White House the “model for efficiency and waste reduction” across the nation and the world.

Dubbed the “Greening of the White House”, the project was hailed as a success since the presidential villa saves more than $300,000 (Sh24 million) annually in energy, water costs, and landscaping since 1996 by enhancing the use of renewable resources.

After the successful greening of the White House, other major buildings like The Pentagon and the US Department of Energy have been given a green makeover.

Britain’s richest man, Lakshmi Mittal, plans to build a £30 million (Sh3.7 billion) mansion in the outskirts of London that designers claim will have a “zero-carbon” footprint once it’s completed.

According to the Sunday Times, the “green house” will be self-sufficient in energy and harness outdoor temperatures to create natural air conditioning.

This, in effect, will not only make the house a zero-carbon emitter, it will also make the entire 340-acre estate that it will stand on carbon-negative.

There are also instances where entire cities have gone green by implementing policies that are geared towards the use of renewable resources in building and transport.

The Dutch capital Amsterdam is one of the cities that have been hailed as nature’s best friends. It is termed the “ultra modern energy-saving metropolis”.

Millions of Amsterdamers prefer bikes to cars and hundreds of homes have registered with an innovative domestic energy management project. All these efforts are projected to slash carbon dioxide emissions by an impressive 45 per cent by 2025.

Nairobi and other major Kenyan urban centres, all of which grapple with perennial power and water shortages and traffic jams, can learn a lot from these urban centres which have implemented revolutionary ways of coping with the vagaries of energy deficiency, pollution, and congestion.

The Kenya Commercial Bank (KCB) is also rushing to complete an eco-friendly building in Upper Hill that is bound to pioneer green architecture in the private sector.

The aptly coloured structure — the company’s corporate colour is green — is funded through the KCB Staff Pension Fund.

Kshs 2.7 billion in Variations for Thika Superhighway Construction Project

The escalating cost of fuel could increase the cost of completing the Nairobi-Thika highway.

This could result in further delay to completion of the Sh27 billion highway, which is scheduled for February next year.

Roads permanent secretary Michael Kamau said the government had a contingency plan to take care of such a predicament.

“If this project is delayed and the fuel prices continue behaving the way they are doing, then we have serious challenges on the amount of money we are going to pay on the variation on price,” the PS said while inspecting the construction progress.

He, however, said the project was nearly half-way done.

“After we changed the contractors, who were doing the re-routing of the water services, the progress level is at six per cent per month,” Mr Kamau said.

He said the contractors were working on the structural works — the underpasses and retaining walls — but had been set back by the current rains.

The PS urged the engineers to gear towards sectional completion of the road.

He noted that the Museum Hill interchange would be ready by July while the works at the Forest and Limuru roads junction were expected to be completed in August.

“We shall be using the flyovers and the traffic jam experienced there shall be eased,” he said, adding that street lights would be put up later.

The highway is expected to ease traffic congestion in the city. China Wu Yi Company, Sinohydro Corporation Ltd and Shengli Engineering Construction are building the highway.

The Brief Is....... Provide Six Million Housing Units in Twenty Years

[caption id="attachment_1503" align="alignnone" width="640" caption="Image of Nyayo Estate in Embakasi. Source: Business Daily Website"][/caption]

Kenya needs a new master plan to help deliver at least six million housing units over the next 20 years if the current housing shortage is to be overcome, architects have said.

According to Mr Steven Oundo, the chairman of the Architectural Association of Kenya, this means that about 300,000 units will need to be produced every year.

Currently, it is estimated that the country produces between 35,000 and 40,000 units a year against a demand of about 150,000 units in urban areas alone.

“This (our proposal) is a realistic target,” said Mr Oundo.

One way of encouraging such developments, he said, was for the government to provide tax incentives, including value added tax exemption on professional services for consultants involved in low-cost development projects worth at least Sh20 million.

The conclusion of the revisions to the building code will also promote the adoption of new technologies in building, considering that it is more performance- than material-specific, he added.

“The high construction cost has been compounded by high taxation of building materials. There are few locally manufactured materials used in Kenya. We are, therefore, exposed to such increases in costs of building materials, compounded by the weakening position of the Kenya shilling against the major world currencies,” he said.

The increasing cost of electricity, he added, also impacts negatively on the construction costs, particularly with regard to cement production where there is heavy consumption of electricity.

“We end up producing cement that is much more expensive than that produced in Egypt or India,” he said.

“We find ourselves in a situation where planning for amenities follows development instead of the actual construction being undertaken on serviced land. This has partly contributed to excessive speculation on land prices.”

Piece of Italy on Mt Kenya by Muchiri Gitonga

War, that bloody business by humanity gone mad, has a way of making the boom of guns, the smell and rivulets of blood, innocence ruined, and ambitions shattered unforgettable by its sheer gore.

War and its memories are also immortalised in brick and mortar to capture and make real what poignancy may evade memory. This would explain the Italian-built shrine in Nyeri and its tree-lined drive and well-tended lawns against the backdrop of the picturesque Nyeri Hill.

It also explains why we have numerous memorial this and that. It is not that those who put up such structures are extravagant. Theirs is a burning desire to keep certain memories, certain fires burning.

Five kilometres from Nyeri town, the Italian War Memorial Church off the Ihururu Road is the eternal home of the remains of 676 soldiers, mostly Italians, captured by British soldiers during the Second World War.

Vaults containing the remains of African soldiers, mostly from Somaliland, who could not be interred inside the church because of their faith, are housed in another structure outside the church. The Somalis had fought alongside the Italians.

On the vaults are engraved the names and dates of death of the soldiers. Lying in front of the two columns of rows of simple wooden pews and just before the altar is one marble-lined tomb. It is that of the Duke of Aosta, Prince Amedeo Savoia-Aosta, the leader of the soldiers.

Benito Mussolini, who lead Italy to the Second World War, had in 1937 made Prince Amedeo the commander-in-chief of all the forces in Italian East Africa.

Mass at the Italian War Memorial Church is held only once a year.

Scores of Italian families, friends, and government officials throng the beautiful brick-walled compound to pay homage to their country’s fallen soldiers.

For Italy, November 4 is set aside to remember the country’s soldiers who died for their motherland, explained former Italian ambassador to Kenya Pierandrea Magistrati.

Last year, Italians living in Kenya marked the day on November 6. A crowd of Italian families, government officials led by then ambassador Mr Magistrati, a few nuns of Italian origin, and a handful of local residents congregated in the church.

Italy’s and Kenya’s flags were hoisted at the entrance.

Green-white-red ribbons hang on the interior walls of the church. The marble tomb of Prince Amedeo left no doubt that this was an Italian state function.

The annual ritual brings together Italians resident in Kenya or other parts of Africa with their families.

Throughout the hour-long mass conducted in Italian by an African priest bathed in soft light from giant candles and windows, two armed soldiers in black and white uniform stand attention on each side of the altar.

The Italian Government and its nationals residing in Kenya funded the construction of the church back in 1952.

Ms Halina Pellin says her family has been coming here for the past 58 years to pay tribute to their father’s cousin, Pellin Armando.

According to Halina, Armando died on August 8, 1946 after he and her father were held captive by the British while fighting in Ethiopia.
Last year, Halina was accompanied by her mother Christina and brother Riccardo Pellin. With her father now dead, the family feels obligated to pay tribute to his cousin as he would have done if he was still alive.

“I never met him,” says Halina as she places her hand on the vault bearing the remains of the departed relative.

“When he died, he was a British prisoner of war alongside my late father. It’s very touching. It signified more for my father who was with him when he passed away.”

The Pellin family has been coming here since 1952.

“It has become our family tradition to attend the annual Mass. In fact, we started coming here long ago when this road was made. It makes us feel closer to our past,” says Riccardo.

Like many of his fellow soldiers, Armando had been captured by the British in Ethiopia and transported to Kenya as prisoners of war. Many of the captives, including Prince Amedeo, would later die of malaria and tuberculosis in the war camps.

One of the legacies of their captivity in Kenya is the Mai Mahiu Road on the scenic escarpment to the floor of the Rift Valley.

In recent years, some Italian families have been repatriating the remains of their relatives for burial in their country.

“It’s true that some families have requested that the remains of their relatives be brought back to Italy. It’s also right to have the remains there,” says Halina, who lives in Kenya.

According to Mr Magistrati, every government has a duty to remember its soldiers who die for the country. He said the Italian Ministry of Defence spends about 6,000 euros (about Sh723,000) in addition to private donations from soldiers’ relatives, to maintain this shrine.

“It’s a symbol of friendship between Italy and Kenya because we have many priests and nuns working around here,” said Mr Magistrati.

After its construction, all the known remains of Italian soldiers in various graveyards in East Africa were gathered and transported to be interred in this architectural masterpiece. This became possible with the help of a committee formed in 1955 for that purpose.

Those buried in the church died as they sought to fulfil the dreams of Italian political and military leaders in the first decades of the 20th century.

The reign of Prince Amedeo as the Governor-General of Ethiopia had been marked by development of infrastructure and high standards of living and general improved quality of life in the new Italian territory.

Under his command, Italian troops accomplished their greatest feat in the Second World War by defeating British troops in British Somaliland.  This victory was, however, short-lived as crucial supply lines for his forces were cut by the British.

Prince Amedeo died in Thika on March 3, 1942, after refusing an offer by the British to be held in England, where he would have been more comfortable until the end of the war.

Kenyan builders building capacity - Winsley Masese

The construction industry is one of the fastest growing in the country and with increased government spending the outlook can only get brighter.

With focus shifting to development of infrastructure in the devolved government, contractors are upbeat that this will increase their revenue streams and experience.

Treasury recently said it would seek Parliament’s approval for Sh3.4 billion in supplementary budget to finance setting up offices and assemblies for county officials.

“This presents us with a key source of income and opportunity to gain experience to serve clients better,” said Mr Dennis Busienei, a director of Mobek Works Company Ltd, based in Bomet.

Though lack of technology is cited as cause for losing out to foreign contractors, especially roads, Mr Timas Gasaya of Gasen Construction Company has a different view.

“Lack of equipment cannot be blamed for not securing a tender as witnessed before as there are equipment for hire.”

The difficult bit, Mr Gasaya points out, is when a contractor is required to finance 5 per cent of the project cost.

To help the sub-sector, the government has approved the formation of a National Construction Authority, through the National Construction Authority Bill, which aims to regulate the sector.

The Bill, to be tabled in Parliament soon, proposes setting up of a fund to support upcoming contractors. The National Construction Authority is expected to replace the National Housing Corporation.

[caption id="attachment_1475" align="alignnone" width="640" caption="Many contractors are said to have weak technical capacity to undertake works of the scope that they are engaged leading to poor quality and unsafe buildings being constructed - Source: Daily Nation"][/caption]

Local contractors argue that they have lost out to foreign contractors as their countries support them financially.

“We do not get support from the government to buy equipment as foreign counterparts and this gives them a competitive advantage,” said Mr Busienei.

Besides, he adds, foreign contractors are given favourable terms as investors with their equipment attracting lower tax as opposed to Kenyan firms importing the same.

During a conference in Nairobi for contractors, Public Works Permanent Secretary Prof John Lonyangapuo said local contractors are notorious for delaying works.

“Those found with delaying projects, ballooning the costs beyond the variation provisions will have their tenders terminated,” he warned.

However, Mr Gasaya said the government must take a share of the blame.

“Every contractor is assigned a quantity surveyor to supervise the work and in case there is poor workmanship or failure to complete work within the stipulated project period, he or she should be held responsible,” he said.

Architectural Association of Kenya chairman Steven Oundo blames the government, consultants, developers and contractor.

“There is poor enforcement of existing building laws and regulations and weak technical capacity in local authorities, corruption and impunity, on the government’s side,” he says. Developers, he says, prefer to use unqualified persons over professionals.

Rise of the Gated Community - Eagle Plains Estate off Mombasa Road

[caption id="attachment_1470" align="alignnone" width="640" caption="Image of Eagle Estate coutersy of The Standard"][/caption]

Hidden off Mombasa Road, about 50 metres behind Panari Hotel, lies Eagles Plain — a breathtaking residential housing estate. It is in close proximity to the city centre and industrial area in a mixed zone and on the way to Jomo Kenyatta International Airport. According to the architect, Andrew Kimani of FNDA Architecture, the estate is erected on a 28-acre plot that holds 307 units.

The single-storied houses have four spacious bedrooms with three bathrooms and a master ensuite. They also have a lounge, dining area, fitted kitchen with a pantry and a detached servant’s quarter. The houses are being sold at Sh11 million up from the initial price of Sh6m. Those who want to rent will have to part with Sh50,000 or more every month.

Surrounding commercial centres like Capital Centre, Panari Sky Centre, Nakumatt Hyper, Nakumatt Embakasi and Metro-Stores along Nairobi-Mombasa Highway caters for major shopping. There is a small shop within the estate for fast moving commodities like milk and bread. Plans are in place to build a commercial centre within the estate.

Each house sits on a 24 by 10 metre space and has cabro worked driveways and a back and front yard. The gated estate has concrete block paving and well-lit landscaped pedestrian walkways. It also enjoys a 24-hour security, which is reinforced by a police post right outside the gate.

Accessing the estate, however, is a challenge and many residents are forced to use a small footpath from Mombasa Road via Nakumatt godown. When it rains it becomes impassable. The main entrance is either through Road C off Enterprise Road or Road C off Likoni Link Road just before Parkside Towers on Mombasa Road. The residents are waiting for the completion of Enterprise Road which begun in 2008 but has since stalled.
