The need for rapid economic development to match increasing population in Nigeria cannot be overemphasised. For this need to be met, it is pertinent that resources in each state and region of the country are efficiently and effectively utilised to maximise return on investments. Thus, it is necessary to identify the catchment area of the current markets to provide an understanding of the market structure which exists at different scales. This study utilised a Geographic Information System (GIS) -based Huff Gravity model to identify the economic catchment areas of major centres. Results show that 13 out of the 14 centres attracted nearby subregions (SRs). The top 7 centres identified accounted for 86% of the potential economic activities. There is a tendency for limited spatial interaction for some SRs in the south in contrast to northern SRs. In conclusion, there is more competition for economic activities among centres in the northern part with the potential to create some winners and losers. Therefore, place-based policies which can enhance economic development across all regions are necessary.

Park and Ride (P&R) systems play a potentially important role in transportation planning to decrease the undesirable effects of private cars in the Central Business District (CBD). In order to achieve this objective, an essential component to be investigated is the catchment areas of these P&R facilities. However, a limited number of studies have applied the Geographic Information System (GIS) to study the spatial boundary accessibility of the catchment areas of P&R. This study aims to analyze the spatial boundary accessibility of the catchment areas of P&R facilities using three GIS methods. The first method uses geometric shapes to analyze the catchment areas of P&R facilities according to regular shapes, such as parabolas or circles. The market area is the second method used to analyze travel time via the tool ArcGIS Network Analyst to determine the catchment area of P&Rs. Finally, the dynamic accessibility method determines how accessible a facility can be through a study of the spatial boundary accessibility of P&Rs based on the travel time and distance between zones and P&R. The result shows that the static methods identify the spatial boundary accessibility through the calculation of the size of the shape of each P&R separately, while the dynamic method identifies the level of accessibility in detail for all P&R and also the accessibility of each zone to reach a facility. In conclusion, the dynamic accessibility method presents better accuracy than static methods in order to estimate the spatial boundary accessibility of the catchment area of P&Rs.

The concept of ‘resilience’ breaks down silos by providing a ‘conceptual umbrella’ under which different disciplines come together to tackle complex problems with more holistic interventions. Acknowledging the complexity of Davoudi’s approach (2012) means to recognize that ‘spatial resilience’ is influenced by many phenomena that are difficult to measure: the adaptation and transformation of a co-evolutive system. This paper introduces a pioneering approach that is propaedeutic to the spatial measure of urban resilience assuming that it is possible to define a system as being intrinsically vulnerable to stress and shocks and minimally resilient, as described by Folke in 2006. In this sense, vulnerability is counterpoised to resilience, even if they act simultaneously: the first includes the exposure to a specific hazard, whereas the second emerges from the characteristics of a complex socio-ecological and technical system. Here we present a Geographic Information System-based vulnerability matrix performed in ESRI ArcGIS 10.6 environment as an output of the spatial interaction between sensitivities, shocks, and linear pressures of the urban system. The vulnerability is the first step of measuring the resilience of the system by a semi-quantitative approach. The spatial interaction of these measures is useful to define the interventions essential to designing and building the adaptation of the built environment by planning governance. Results demonstrate how mapping resilience aids the spatial planning decision-making processes, indicating where and what interventions are necessary to adapt and transform the system.

Local Embeddedness

The article addresses possibilities and barriers to economic activity and development in the Oshana region of Northern Namibia. The focus is on the role of local embeddedness of economic activities in attaining economic development. A network perspective, based on theories of value chains that are embedded both in social relations and spatially, is selected as the analytical framework. The value chains of local black entrepreneurs in the study area are short. Moreover, the analysis reveals that social obligations may impede economic development, but that such practices are diminishing. The economic dominance and competition from South Africa is the main impediment to economic development in Northern Namibia. Local political embeddedness is shallow and political measures have not significantly reduced the implications of this dominance.

The Relationship

Land intended for urban use is becoming increasingly concerned in our society, mainly for environmental reasons. In turn, it is an excellent indicator of the economic development of the territory. This study evaluates the urban area's change between 1990 and 2018 in Portugal Mainland and its relationship with the population. To achieve this aim, a Geographic Information System was used, and based on Corine Land Cover (CLC) data, the urban area occupied in 1990 and 2018 was determined. Also, together with the population in 2011, they formed a multi-temporal database. An exploratory analysis was carried out on it. The relationship between the population was analyzed in 2011 and the occupied urban area in 2018. Finally, the statistical inference was used, comparing the occupied urban area's average populations in 1990 and 2018. The results suggest that urban expansion has been very significant and identified the territories with the highest growth.

Life On Earth

Climate change is the most complex challenge that humankind has had to face in recent times. With each successive generation, redressing the imbalance will be more difficult. Diverse and complex requirements of maintaining life on Earth, collectively called the environment, can be caused both by natural, geophysical factors, and anthropogenic or social factors. There is a lot of evidence that the economic activity of mankind is a major anthropogenic factor in current turmoil of the environment on Earth. Since the middle of the nineteenth century, the anthropogenic impacts on the environment are becoming increasingly important, and undoubtedly dominate. Of all forms of economic activity the greatest impact have the activities related to energy production and use in various sectors. The link between environmental conditions and economic activities has become the subject of separate scientific disciplines that are dynamically developing in the second half of the twentieth century.Economic growth of the economies, especially of developed countries, in seventies and eighties of the twentieth century, drew attention to the growing international economic, political and ecological interdependence, particulary in terms of its ecological outcome. The future economic growth of all countries on the planet thus becoming a global problem.In this context, more attention must be paid to the relationship between population, resources, and environmental outcomes on one side, and long-term sustainable economic development on the other side. In the recent time there have been noticeable the increasing number of problems that are becoming global: economic, social and energy problems, and contain ecological basis. Human decisions and acivities are dependent on ethics and view of the world, and this view depends on the culture, tradition, achieved level of development and so on.Therefore, it is necessary to adjust economic development to climate change, where a great importance plays a cooperation between the public and private sector.

Most writings on Sabah's socio-economic development tend to focus on the roles by the British and other Europeans but neglect contributions by the Japanese, who were at least equally important to Sabah's economic growth. This article provides a study of Japanese economic activity in Sabah, focusing on immigrant workers and highlighting the policies of successive Japanese governments toward emigration to Sabah.
