    UN-Habitat projects Sub-Saharan Africa’s global share of the urban population to increase from 11.3% in 2010 to 20.2% by 2050. Yet little is documented about the underlying urbanization processes, particularly of emergence of small towns. This article uses household interviews, focus groups, observation, and secondary data to examine the spontaneous transformation of a western Sudanese village, Shubbola, into a small town. We use changes in building construction approach, materials, and style as an indicator of development and provide rare documentation of the process, the main actors, choices taken, timescales, and outcomes of the rapid urbanization of Shubbola between 2006 and 2013. Housing transformation was variable but involved a gradual process of replacing traditional non-durable building materials (wood and straw) with modern durable ones (sun- or fire-cured bricks, cement blocks, and metal roofs). Unlike traditional top-down models of urbanization generally driven by government investment, Shubbola epitomizes an organic, bottom-up process dependent on self-reliance and agriculture development fueled by remittances from urban-based relatives. While many small towns with similar origins fail to do so, Shubbola already provided important urban services to its inhabitants and surrounding rural areas. The study enhances understanding of small towns and underlying urbanization processes and their contribution to often neglected bottom-up, low-cost processes that do not fit traditional top-down models. It also contributes to literature and policy on sustainable cities and their role in sustainable development as encapsulated in UN Sustainable Development Goal 11. The study contributes to understanding the processes and implications of rapid urbanization in the Sudan and Africa and other world regions

    O desempenho do produto agrícola brasileiro no período após a II Guerra Mundial é digno de nota, porquanto os aumentos da oferta vêm se adaptando ao crescimento da demanda e a suas alterações entre grupos de bens, mantendo, dessa forma, os preços reais do géneros alimentícios relativamente constantes. Isto se verificou apesar do descuido, e mesmo da implementação de políticas adversas ao setor agrícol
