Professor Peter Newman BSc, Ph.D, Dip.ES&T, an expert in the field of sustainability of Curtin University, revealed that the population density plays an important role in sustainable development. Especially for cities with low population density in the world, where the city is dependent on the use of the car for the day-to-day activities which are very consumptive of natural resources.

Fuel use decreases exponentially as density increases, said Peter while giving a lecture to students of the Department of Urban and Regional Planning at the auditorium FTUB Prof. Ir. Suryono, Wednesday (4/3).

Peter statement is based on research entitled Cities Data Base for 2005 Curtin University Sustainability Policy (CUSP) in 2010. This study revealed that the amount of per capita energy consumption in the transportation sector in the major cities is inversely proportional to the increase in urban population density. The greatest use is in Atalanta City, United States, where the average value of energy consumption in the transport sector is 103,000 MJ/person with a population density of 5.5 persons/ha. While Hong Kong with an average population density of 322 persons/ha use of energy in the transport sector only in the range of 4000 MJ/person.

This can’t be separated from the fact that people in downtown prefer walking, cycling, or use public transportation for their activities. While the community who live in the suburbs use private vehicles (cars and motorcycles) or a taxi for their activities.

Then from the book that he created in 1989, entitled “The End of Automobile Dependence”, there are two solutions on how to switch from urban planning based on personal vehicle (car). The first is reorienting the city’s transport priorities. Second, hold urbanization to areas of high¬†density population.

He also rejected the myths that developed in the community about the adverse effects of increasing density of population by presenting the contrast facts. In fact, the results of the calculations he did on the City of Perth, the rebuilding of the city into a centralized area with dense population than back toward the outskirts of urban development with a low density population can save up to 212.9 billion Australian dollar for 30 years.

How do we think about Malang and population density? Peter gave his opinion, Malang require re-municipal planning, especially where to place the population density. He added that the settlement areas need to be built organically. Not to forget the campus area should be rebuilt into a pleasant area for pedestrians.

“High density is the higher possibility to Achieve sustainable transportation. Do not be afraid of density,” Peter closed his lecture. (and/mic)
