Global South Urbanization Does Not Have to Harm Biodiversity

Thursday, June 25, 2015 at 9:34AM

How to balance fragile ecosystems with rapid urbanization will be the challenge for planners and governments across the global South in the coming years. The urbanization trend is clear: the world’s total urban area is expected to triple between 2000 and 2030, with urban populations set to double to around 4.9 billion in the same period (UNEP). This urban expansion will draw heavily on water and other natural resources and will consume prime agricultural land.

Global urbanization will have significant implications for biodiversity and ecosystems if current trends continue, with knock-on effects for human health and development, according to a new assessment by the United Nations Convention on Biological Diversity (CBD).

Cities and Biodiversity Outlook – the first global analysis of how projected patterns of urban land expansion will affect biodiversity and crucial ecosystems – argues that promoting low-carbon, resource-efficient urban development can counter urbanization’s adverse effects on biodiversity while improving quality of life.

“The way our cities are designed, the way people live in them and the policy decisions of local authorities, will define, to a large extent, future global sustainability,” said Braulio Dias, Executive Secretary of the CBD.

“The innovation lies not so much in developing new infrastructural technologies and approaches but to work with what we already have. The results often require fewer economic resources and are more sustainable,” he added.

The report says urban expansion is occurring fast in areas close to biodiversity ‘hotspots’ and coastal zones. And rapidly urbanizing regions, such as large and mid-size settlements in sub-Saharan Africa, India and China, often lack resources to implement sustainable urban planning.

But the study found that cities do not need to be in conflict with plant and animal species and ecosystems. They can, in fact, protect species, as is the case with Belgium, where 50 per cent of the country’s floral species are found in Brussels, or Poland, where 65 per cent of the country’s bird species occur in Warsaw.

At the Alexander von Humboldt Research Institute in Bogota, Colombia (humboldt.org.co) researchers have been thinking about how to get this balance right and make sure the growing cities of the future are not ecological disasters.

According to Juana Marino and Maria Angélica Mejia at the Institute’s Biological Resources Policy Program – which investigates “Biodiversity, Ecosystem Services and Urban-Regional Environments” – how cities grow and develop must change.

They believe cities need to take into account the resources they require to function and the impact this has on biodiversity and ecosystems.

“The more people who arrive in cities, the more they demand goods and services (in a massive way!): roads, housing, infrastructure, food, water – (creating) an impressive amount of waste, challenging traditional waste management and sanitation policies,” said Marino.

In short, “Cities enhance consumption.”

The Humboldt researchers believe common patterns can be seen across the global South, where ecosystems “surrounding urban areas are deforested and have significant levels of water and air pollution; they also become deeply transformed by informal settlements.”

This process means cities “lose their ability to be resilient, they become highly vulnerable to global change and they decrease their production of ecosystem services to maintain human well-being in cities.”

They argue that human settlements must be sustainably planned for, with ecological resilience and human well-being. If this is not done, areas suitable for agricultural production and biodiversity preservation will be harmed.

While better planning is needed there also needs to be long-term thinking.

But planning and managing are not the only things required: “it is a matter of design” if new “resilient” urban-rural landscapes are to be created.

And what can be done? They believe better analysis is required and it needs to take on social and cultural knowledge, and take in the border regions around cities, the “suburban, peri-urban and other ‘transition’ landscapes should become main actors in these relationships, not mere by-products; (they are) compromise territories between a lack of definition and low governance.”

These complex relationships with the border ecosystems of cities need to be communicated to the general public in simple, user-friendly ways so they can understand how important these areas are to the overall health of the city.

In Latin America, the cities of Curitiba (Brazil) and Bogotá and Medellin (Colombia) have made great strides in managing and planning for biodiversity and ecosystem services, they say. But it is not just as simple as recording the number of native species and the percentage of protected areas in urban places. Links need to be created between “social, scientific and political” elements to create “socio-ecological indicators” that can be developed and turned into “easy-to-adopt mechanisms” for people to use.

And they see innovation as the way to do this. Innovation is critical if cities and urban areas are to avoid widespread destruction of biodiversity as urbanization increases.

“Innovation is not just an option – it is a ‘must’,” said Marino. “Not just the technical innovation already being carried on by infrastructure, transport and building sectors that are rapidly changing their patterns based on mitigation technologies.

“Innovation is also needed in terms of biodiversity, biotechnology, information and knowledge production; appropriation, use and management. Knowledge turns into innovation when appropriated by social spheres; when it enters the social and political arenas.”

Environmental governance can be strengthened “when promoting top-down and bottom-up innovations.”

Development Challenges, South-South Solutions was launched as an e-newsletter in 2006 by UNDP's South-South Cooperation Unit (now the United Nations Office for South-South Cooperation) based in New York, USA. It led on profiling the rise of the global South as an economic powerhouse and was one of the first regular publications to champion the global South's innovators, entrepreneurs, and pioneers. It tracked the key trends that are now so profoundly reshaping how development is seen and done. This includes the rapid take-up of mobile phones and information technology in the global South (as profiled in the first issue of magazine Southern Innovator), the move to becoming a majority urban world, a growing global innovator culture, and the plethora of solutions being developed in the global South to tackle its problems and improve living conditions and boost human development. The success of the e-newsletter led to the launch of the magazine Southern Innovator.

Tiny Homes to Meet Global Housing Crisis

Monday, June 22, 2015 at 11:06AM

More than 1 billion people around the world lack decent shelter. Of these, the majority live in urban areas, usually in slums and informal settlements (UN-HABITAT).

The world’s megacities – like Mumbai, India, where more than 22 million live in the metropolitan region – have to find a way to provide housing that is both affordable and does the minimum possible amount of harm to the environment.

About one-third of the world’s urban dwellers live in slums, and the United Nations estimates that the number of people living in such conditions will double by 2030 as a result of rapid urbanization in developing countries.

The fast pace of growth of India’s cities presents an enormous challenge: how to house so many people with dignity and to a good standard. India’s city slums are notorious and recently became the subject of the Oscar-winning film Slumdog Millionaire (http://www.slumdogmillionairemovie.co.uk/).

With a population of 1.2 billion, India needs to find 25 million homes a year to meet current demand, according to McKinsey and Co.

Housing prices have risen by 16 percent a year for the past four years. While the middle class – estimated at over 300 million people – has piled into high-end apartments and houses, it has been the country’s low-income people who have been frozen out of the option of quality homes.

The concept of targeting those at the ‘bottom of the pyramid’ (BOP) (http://en.wikipedia.org/wiki/The_Fortune_at_the_Bottom_of_the_Pyramid) has drawn attention to the estimated 23 million poor urban dwellers in India, and 180 million rural families, who have savings and want to own a home. Monitor India (http://www.monitor.com/in/) believes these people have annual earnings between US $1,400 and US $3,000.

The Indian manufacturing powerhouse Tata – which this year launched a BOP-focused car, the Tata Nano – has designed and is building, Nano Homes – small apartments outside Mumbai for US $8,600 (http://tatahousing.in/pages/home.php). It also hopes to expand to other major Indian cities as well.

The Nano homes are built on a modest scale: there are three sizes with the smallest measuring 67 square metres. They consist of a single room that doubles as a bedroom by night with a sink, bath and toilet behind a partition.

Criticisms include location – on the edges of major cities – where residents would have to commute long distances to get to their jobs.

Even so, Nano apartments are so popular buyers are being chosen by lottery.

“India’s housing crisis lies in the fact that the poor in the cities are priced out of the market,” Sundar Burra, an adviser to the Society for the Promotion of Area Resource Centre, a Mumbai-based housing rights organization, told Canada’s Globe and Mail newspaper.

“State supply of housing for the poor is woefully inadequate in relation to the need. Slums proliferate as a solution to this state of affairs.”

People can get a mortgage for the homes from Tata Home Finance.

Tata is not the only company targeting this market. India’s Matheran Realty (http://www.tmcity.in/) is building what it claim is India’s largest affordable housing project, Tanaji Malusare City, in the villages of Shirse and Akurle of Karjat (http://en.wikipedia.org/wiki/Karjat). The 15,000 homes would house 70,000 people and would sell for US $4,698.

Another developer, Godrej Properties (http://www.godrejproperties.com/), is building a BOP housing development outside the city of Ahmedabad with apartments costing US $11,749.

“(Property) developers have recognized that the real demand no longer lies in the premium segment and are opting to build smaller, no-frills apartments,” said Deepak Parekh of the Housing Development Finance Corporation (http://www.hdfcindia.com/).

It estimates the affordable housing market will be worth US$ 110 billion in India by 2013 and will account for 80 percent of India’s housing market.

“Affordable housing is not about box-sized, budget homes in far-flung places where there is no connectivity to workplaces and little surrounding infrastructure,” Parekh told HDFC’s shareholders. “Affordable housing has to be able to cut across all income segments and has to make economic sense in terms of proximity to the workplace.”
