Cities occupy only about 3% of the Earth’s surface area, but half of the global population lives in them. The high population density in urban areas requires special actions to make these areas develop sustainably. One of the greatest challenges of the modern world is to organize urban spaces in a way to make them attractive, safe and friendly to people living in cities. This can be managed with the help of a number of indicators, one of which is walkability. Of course, the most complete analyses are based on spatial data, and the easiest way to implement them is using GIS tools. Therefore, the goal of the paper is to present a new approach for measuring walkability, which is based on density maps of specific urban functions and networks of generally accessible pavements and paths. The method is implemented using open-source data. Density values are interpolated from point data (urban objects featuring specific functions) and polygons (pedestrian infrastructure) using Kernel Density and Line Density tools in GIS. The obtained values allow the calculation of a synthetic indicator taking into account the access by means of pedestrian infrastructure to public transport stops, parks and recreation areas, various attractions, shops and services. The proposed method was applied to calculate the walkability for Kraków (the second largest city in Poland). The greatest value of walkability was obtained for the Main Square (central part of the Old Town). The least accessible to pedestrians are, on the other hand, areas located on the outskirts of the city, which are intended for extensive industrial areas, single-family housing or large green areas.

This paper proposes a new approach for monitoring of managing the modernisation of regional economic. The model built on proposed methodology will make it possible to smooth out the influence of non-urban areas on the unevenness of economic activity in spatial development. This paper has two goals. The first is to provide a new compilation of data on spatial distribution of economic activity at the sub-regional level. This data set allows us to monitoring of different indicators within macroregions such as Siberia. The second goal is to construct an instrument that helps to overcome the endogeneity problem using new economic geography hypothesis about the mechanisms of distribution of economic activity. Section 2 describes the data and method that we have proposed, discusses the construction of the Theil indexes using these data at the sub-federal and the sub-regional level. Section 3 presents the correlations between spatial distribution of economic activity and local market potential, discusses the robustness of the results; and the last section concludes.


A non-westernized nation’s food security often depends on preservation of rural agricultural livelihoods, yet a globalizationdriven international effort to “develop” societies by providing modern infrastructure has focused on population centers, creating two-tiered economies that frequently leave rural populations behind. As a result, young residents of rural communities are migrating with greater frequency to urban areas, viewing their home society as outdated and irrelevant. To address this disparity, organizations and volunteer groups attempt to deliver infrastructure interventions to small rural communities, often drawing upon their own experience or out-of-the-box designs to provide water, sanitation, transportation, or energy. The success rate of these interventions in meeting societal needs are marginal at best, often disregarding indigenous practices and beliefs and further demeaning rural lifestyles. A new approach is needed to stabilize rural communities and sustain agricultural livelihoods throughout the alternately developed world through quality-of-life improvements via engineered infrastructure. Contextual engineering merges technical design with sociological understanding to identify the critical influences that govern each client community, dispensing with the artifice of scalability to address specific physical needs. By focusing on client society beliefs, values, and needs, the infrastructure designer may better create an affordable, functional, and appropriate infrastructure to support and advance that rural society. This paper will present the contextual engineering concept’s potential to support rural growth for stronger agricultural productivity and national food security.

This chapter discusses a new approach to the study of urban place, “the scenes approach.” While this approach is not exclusively applicable to cities, this chapter is focused on urban areas. Businesses and institutions, people and practices join to produce areas with distinct aesthetics—hip, edgy, refined, glamorous, etc. These qualities make it possible to move about a city as if it were a scenic route, to discover the styles of life each has to offer. This chapter is intended as a first effort to extend scenes thinking to historic preservation and public heritage practice (and vice versa) and we invite critical dialogue and collaboration.

The first and second AutoOil programmes were conducted since 1992 as a partnership between the European Commission and the automobile and oil industries. These have introduced emission reductions in Europe based on numerical modelling for a target year. They aimed to identify the most cost-effective way to meet desired future air quality over the whole European Union. In their time, these regulatory efforts were considered an important step towards a new approach for establishing European emission limits. With this work, we review the effectiveness of forecasts carried out with numerical modelling and compare these with the actual measurements at the target year, which was the year 2010. Based on these comparisons and new technological innovations these methodologies can incorporate new sectorial assessments for improving the accuracy of the modelling forecasts and for examining the representativeness of emissions reductions, as well as for the simultaneous assessment of population exposure to cocktails of toxic substances under realistic climatological conditions. We also examined at the ten AutoOil domains the geographical generalisation of the forecasts for CO and NO2 at 1065 European urban areas on the basis of their population and the local population density.

This paper examines whether financial-sector policy changes introduced in Tanzania during the last decade have improved bank finance availability to small enterprises. Study findings reveal that, despite these changes, the level of bank finance to small enterprises is still insignificant. Results likewise indicate that, apart from bringing about limited competition in the provision of financial services, these changes have resulted in the concentration of most financial institutions in urban areas and in only a few regions/provinces. This also negatively affects bank finance availability to small enterprises. These findings have several policy implications for the growth of small enterprises in the country. Key among them is the need for a new approach to policy that will improve bank finance availability to small enterprises.
