Argentina's path to economic prosperity is through efficient, sustainable and economically thriving cities. Not only are cities a spatial concentration of people, but also they generate agglomeration economies by concentrating ideas, talent, and knowledge. Argentina is one of the most urbanized countries in Latin America, with 90 percent of Argentine people currently living in cities. Argentina's cities are geographically and economically diverse, and its largest urban area – Metropolitan Buenos Aires – is one of Latin America's urban giants. Argentine cities need to address three main challenges to leverage their economic potential. Argentina's current patterns of urban development are characterized by (a) high primacy and unbalanced regional development, (b) limited global economic footprint of urban economies, with employment concentrated in nontradable and resource intensive sectors, and (c) unplanned low-density urban expansion. Argentine cities thus face the challenges of moving toward a more balanced regional development, transitioning from local to global cities, and from urban sprawl to articulated densities to take full advantage of the benefits of agglomeration economies. To address these challenges, Argentina needs the leadership of the federal government; the coordinating power of provinces; and the capacity of empowered, financially sound municipalities. Argentine cities also need system-wide policy reforms in areas such as territorial planning, municipal finance, housing, urban transport, and local economic development. Leveraging the Potential of Argentine Cities: A Framework for Policy Action aims to deepen our empirical understanding of the interplay between urbanization and agglomeration economies in Argentina by asking the following: (a) What are the main trends and spatial patterns of Argentina's urbanization that underlie agglomeration economies?, (b) Are urban policies leveraging or undermining the benefits of agglomeration economies?, and (c) Are Argentine cities fully reaping the benefits of agglomeration economies to deliver improvements in prosperity and livability? By addressing such questions and exploring their implications for action, this study provides a conceptual framework, empirical data, and strategic directions for leveraging the potential of Argentine cities.

OBJECTIVE. To describe the prevalence of "active" (self-propelled, human-powered) transportation in the Latin America and Caribbean (LAC) region over the past decade. METHODS. MEDLINE, Excerpta Medica (Embase), SportDiscus, Lilacs, MediCarib, Web of Science, OVID, CINAHL, Scopus, Google Scholar, National Transportation Library, and TRIS/TRID were searched for articles on active transportation published between January 2003 and December 2014 with (at least) a title and abstract in English, Portuguese, or Spanish. Research was included in the study if the two reviewing authors agreed it 1) was conducted in an adult sample (≥ 18 years old), 2) was designed to be representative of any LAC area, and 3) reported at least one measure of active transportation. Reference lists of included papers and retrieved reviews were also checked. A total of 129 key informants (87 scientific experts and 42 government authorities) were contacted to identify additional candidate publications. Two other authors extracted the data independently. RESULTS. A total of 10 459 unique records were found; the full texts of 143 were reviewed; and a total of 45 studies were included in the study, yielding estimates for 72 LAC settings, most of which were in Argentina, Brazil, and Colombia. No eligible studies were found for the years 2003–2004, resulting in a 10-year study time frame. Estimates were available for walking, cycling, or the combination of both, with a high degree of heterogeneity (heterogeneity index (I2) ≥ 99%). The median prevalence of active transportation (combining walking and cycling) was 12.0%, ranging from 5.1% (in Palmas, Brazil) to 58.9% (in Rio Claro, Brazil). Men cycled more than women in all regions for which information was available. The opposite was true for walking. CONCLUSIONS. Prevalence of active transportation in LAC varied widely, with great heterogeneity and uneven distribution of studies across countries, indicating the need for efforts to build comprehensive surveillance systems with standardized, timely, ...
