Abstract Background Currently, most of the world’s population lives in cities, and the rapid urbanization of the population is driving increases in the demand for products, goods and services. To effectively design policies for urban sustainability, it is important to understand the trends of flows in energy and materials as they enter and leave a city. This knowledge is essential for determining the key elements characterizing future urban growth and addressing future supply challenges. Methods This paper presents an analysis of the energy and material flows in the city of Bogotá over the time span from 2001 to 2017. Urban flows are also characterized in terms of their temporal evolution with respect to population growth to compare and identify the changes in the main input flows, wealth production, emissions and waste in the city. Results The results of the analysis are then compared with those for other selected large urban agglomerations in Latin America and worldwide to highlight similarities and make inferences. The results show that in Bogotá, there was a decrease in some of the material flows, such as the consumption of water and the generation of discharge, in recent years, while there was an increase in the consumption of energy and cement and in the production of CO2 emissions and construction materials. Solid waste production remained relatively stable. With respect to the other large cities considered, we observe that the 10-year growth rates of the flows with respect to population growth are lower in Bogotá, particularly when compared with the other urban agglomerations in Latin America. Conclusions The findings of this study are important for advancing characterizations of the trends of material and energy flows in cities, and they contribute to the establishment of a benchmark that allows for the definition and evaluation of the different impacts of public policy while promoting the sustainability of Bogotá in the coming decades.

In the 1960s, Addis Ababa experienced a construction boom, spurred by its new international stature as the seat of both the United Nations Economic Commission for Africa and the Organization of African Unity. Working closely with Emperor Haile Selassie, expatriate architects played a major role in shaping the Ethiopian capital as a symbol of an African modernity in continuity with tradition. Haile Selassie's Imperial Modernity: Expatriate Architects and the Shaping of Addis Ababa examines how a distinct Ethiopian modernity was negotiated through various borrowings from the past, including Italian colonial planning, both at the scale of the individual building and at the scale of the city. Focusing on public buildings designed by Italian Eritrean Arturo Mezzedimi, French Henri Chomette, and the partnership of Israeli Zalman Enav and Ethiopian Michael Tedros, Ayala Levin critically explores how international architects confronted the challenges of mediating Haile Selassie's vision of an imperial modernity.

The matters of the mechanism of management of development of the city-forming organizations of the construction industry, forms of interference of development of the city-forming organizations and mono-profile municipal unit are defined in the article. The main methodical approaches to the assessment of effectiveness of realization of the mechanism of management of development of the city-forming organizations of construction industry are proved. Assessment of effectiveness of realization of the mechanism of management of development of the city-forming organizations to the sphere of production of construction materials are considered according to the ecological-and-economic aspects of sustainable development, including economic efficiency, social efficiency, environmental efficiency.

The strongest point of vernacular architecture is the harmony between environment and buildings. Mediterranean vernacular architecture is harmonized with its local context, including culture and traditions. In addition, it respects environmental and climatic factors, construction materials, and morphology. In the past, people in Palestine built their houses according to their possibilities, needs, available materials, topography, and culture. Without any control from the government or any legal limitations or architects, it was people’s architecture, simple architecture. This paper discusses the differences between vernacular and contemporary residential buildings of the city of Nablus at the building scale. The research methodology adopts explanatory qualitative analysis and comparative synthesis methods for both the old and the new buildings of the city of Nablus and considers many parameters of residential buildings such as building materials, interior spaces, openings and vegetation, and the effect of sociocultural values on each. The outcomes of this research allow understanding how the new city residential buildings are far away from the sustainability principles and how the old city is close to it and how the architects and stakeholders could learn from the strategies of vernacular architecture.

Abstract Human beings could be exposed to impacts associated with heavy metals such as lead (Pb) through drinking water. The objective of this study was to evaluate quality of water consumed by kindergarten school children in Addis Ababa city, who are highly susceptible to issues related to heavy metals in water. Through conducting chemical analysis, using microwave plasma atomic emission spectrophotometry (MP-AES), the level of lead (Pb) was measured at 38 selected schools in the city. Drinking water samples were taken from three water supply sub-systems: Akaki, Legedadi, and Gefersa. Results revealed the average Pb concentration in the city was 62.37 μg/L which is significantly higher than the World Health Organization (WHO) recommended threshold value of 10 μg/L. The children's blood lead levels and exposure to Pb were also calculated using the integrated exposure uptake bio-kinetic (IEUBK) model as per USEPA guidelines. Estimated geometric mean blood lead levels (BLLs) for each school ranged from 4.4 to 13.2 μg/dL. On average, the model predicted that 20% of children in the city will have blood lead levels above the WHO recommended 10 μg/dL. The study can be considered as an unprecedented piece of work as it addresses critical issues and methods to mitigate problems caused by high concentration of Pb in water supply distribution infrastructure.

Purpose Despite the large interest in urban food markets, there are, however still relatively few good studies that have empirically documented the functioning of retail markets in developing countries, especially in Africa. The purpose of this paper is to look in particular at the case of Addis Ababa, a city of more than four million people and the capital of Ethiopia, one of the most populous countries in Sub-Saharan Africa. To better understand urban food retail, the authors rely on a large primary survey. Design/methodology/approach To better understand urban food retail, the authors rely on a large primary survey. Based on a stratified sampling scheme representative for the city as a whole, 1,226 urban food retail outlets were interviewed in March and April 2012. Findings The authors find increasing differentiation in food retail markets in recent years. Despite the prohibition of foreign direct investment in food retail, a domestic modern private retail sector is quickly emerging. However, its share is still very small and, in contrast to roll-outs of modern retail in other countries, it has not yet entered the cereal sector, which remains in the hands of local flour mills, cereal shops, and cooperative retail outlets. The importance of cooperative retail is growing even more rapidly. It is especially important for those products where supply chains are controlled by the government. On the high-end, domestic private modern retail outlets deliver high-quality products at significantly higher prices, ceteris paribus. At the other side, the authors see cooperative retail that delivers food at significantly lower – and subsidized – prices. However, the latter shops are characterized by typical price control problems, reflected in regular lack of supplies and queuing. Research limitations/implications The study is limited to the city of Addis Ababa and it seems useful if similar studies could be conducted in other cities in Africa. Originality/value Despite the large interest in urban food markets, there are still relatively few good studies that have empirically documented the functioning of retail markets in developing countries, especially in Africa. The paper therefore contributes to fill this lacuna by studying urban food retail markets using new and unique data for Africa.
