Learning from Medellín with Alejandro Echeverri

“I think, if you want to write a new narrative at some specific moment in the story of a city, it is important that you have to feel the transformation and see the transformation. So the physical transformation is important but always there is more a spiritual thing, as happens with emotional connections and inspirational things.” ______Architect Alejandro Echeverri.

EcheverriPhotoIf you have an interest in Latin America or in urban matters, you will have read by now that the city of Medellín, Colombia has undergone a startling transformation in the past fifteen years. In the 1980s and 1990s, the name of Medellín evoked fearsome drug cartels, violence and terrorism.

But in the 2000s, Medellín took a dramatic turn for the better. In 2012, it was selected from 200 contenders as Innovative City of the Year in a survey organized by the Wall Street Journal and the Urban Land Institute. Today, it features regularly among lists of forward-looking cities and must-see destinations. Read more

Portfolio 019 – Manhattan Ultra-Luxury ‘Battling the Serpent of Chaos’

The deceleration of China and resulting commodities crash have created a problem for developers of ultra luxury condominiums.

The ancient Egyptians believed that the sky was a solid dome, the belly of the goddess Nut who arched her body from one side of the horizon to the other. Every day, the sun god Ra emerged in the east and sailed in his boat across the sky until dusk when he disappeared in the west by dipping below the surface of Nun, the ocean upon which the whole flat earth floated.

Rise of the Rest: A Vision Deferred

Changing demographics and the commodities crash have slowed down the development of poorer countries.

Perhaps it all started with a turn in China’s demographics. Demand growth for commodities has declined sharply from recent years and has resulted in a crash of global prices. Copper is down 54% from its post 2008 peak and down 25% this year alone. Crude oil is down 67% and 39% in the same time spans. In addition to softer demand, prices were negatively impacted by jumps in supply, most notably from shale energy producers in the United States. Read more

In One Chart: Achieving the Demographic Dividend

The experience of China provides a useful policy template for countries with booming populations in south and southeast Asia and in sub-Saharan Africa. The Chinese boom showed that a growing working-age population combined with a declining fertility ratio can result in a large demographic dividend if certain conditions are met. As noted in this recent post, two important drivers of lower fertility are an increase in female literacy and a decline in child mortality. Read more

How Many People Will Live in Africa in 2050 and 2100?

Large declines in fertility will depend on raising female literacy above 80%.

Every few years, the United Nations Population Division releases demographic projections for the entire world and for every country, region and continent. Although the UN’s database is the most used source on demographics, the data is not equally reliable for all countries.

Countries in the developed world conduct regular censuses and produce detailed numbers that are considered reliable. Less developed countries conduct censuses on an irregular basis or are completely unable to conduct them and have instead to rely on demographic sampling. In the poorest countries of the world, most of which are in sub-Saharan Africa, censuses are infrequent or nonexistent and even sampling can be irregular and unreliable. Read more
