Title
Meeting the urban growth challenge: Expanding the supply of urban land strategically.
Focus
The lecture/paper discusses 10 considerations for expanding the supply of affordable serviced land, strategically.
Issues which the lecture addresses
The lecture recognized UN-Habitat’s Three Pronged Approach to planned urbanization, highlighting the need for a complementary approach, integrating design, finance and regulation, in order to expand the supply of land strategically. Thereby, the lecture overcomes the conventional approach that master plans expanding the urban footprint (or containing it) are sufficient instruments in order to steer and implement urban growth strategies.
Short analysis of the above issues
Rapid urbanization takes place. Now. And its magnitude is without precedence. “The increase of the urban population of 2.8 billion people between 2010 and 2050 is forecast to be higher than the total population of the world of 2.5 billion in 1950”. (UN Secretary-General, 2012) However, the expected increase in the urban built-up area takes place at an even higher pace. “Double population—triple area: the urban built-up area is expected to triple between 2000 and 2030” (World Bank, 2005)
During rapid urbanization, societies face many land-related challenges, such as: land identification, assembly, site planning, infrastructure development and financing. If these challenges are not adequately addressed, then “2 billion people could be living in urban slums by 2030.” (UN-Habitat)
The lecture begins with the traditional understanding of “land supply”, correlated with the point of view of architects, designers and planners: meaning either the urbanization of new peripheral areas (planned city extensions, manufacturing corridors, etc.) or the densification of underdeveloped inner-urban areas (planned city infill, urban renewal, slum upgrading, etc.) However, the initial point too often ignores necessary complements, which may constitute binding constraints to meeting the demand of land in an inclusive, safe, resilient and sustainable way (cf. SDG 11). Too often this leaves the urban poor behind, unable to access formal, serviced land at a desirable location.
Therefore the lecture quickly expands the discussion, promoting a multi-pronged, interdisciplinary approach:
• Larger planning/design questions show how to expand the supply of land: be it through developing denser compact cities or through expanding urban boundaries. They also show why and how to invest into urban mobility systems and how to develop urban sub centers.
• Legal considerations highlight key strategies for reducing the overall cost of land as a housing input, for example through permitting higher densities, as well as for lowering the entry barriers to the formal land and housing markets, for example through relaxing minimum plot requirements.
• Fiscal policy options show how to (and how not to) finance the supply of serviced land, for example through land value taxation and land value capture mechanisms.
• Lastly, the discussion builds a bridge to incrementalism (see Goethert’s lecture), as the incremental development of affordable dwellings, the incremental development of affordable habitats (i.e. land serviced with infrastructure and amenities) and the incremental financing thereof require a larger, integrated urban strategy supporting the evolution of cities, neighborhoods and homes over time.
Propositions for addressing the issue
The following is a list of the 10 considerations:
1. Service and zone land for urban use.
2. Remove wasteful regulations, obstructing land use efficiency.
3. Invest in mass transportation and alternative mobility.
4. Promote sub-centers and intra-urban equality.
5. Encourage mixed-use mixed-income settlements.
6. Balance the social and environmental costs of urbanization.
7. Share land value increases fairly between stakeholders.
8. Release underdeveloped lands to the market.
9. Tax land value to promote efficiency and equity.
10. Plan for housing careers and incremental development.
