Set Up

Cameroon through its Strategy for Growth and Employment (DSCE), has set up the construction of the Yaoundé-Nsimalen highway project. As part of the assessments of its potential effects on the environment, an ESIA was carried out, according to the framework law on the management of the environment. The acquisition of housing has resulted in an '' anarchic '' installation in the urban and peri-urban area. The construction of a highway as planned overlays on these facilities and poses a problem related to the liberation of spaces previously occupied. The purpose of this study is to identify, locate and classify the impacted goods by the highway construction project through Geographic Information Systems (GIS). Our methodology consisted first, making a satellite identification of the impacted goods, then a field campaign and finally a processing of the data collected. This study was also limited to the identification of two types of property, the buildings and parcels of land. Thus, it has been possible to distinguish and locate six categories of buildings, eight categories of parcels of land defined according to the Cameroon law No. 85/009 of 04 July 1985 on the expropriation for public purpose and the terms of compensation and according to Order No. 0082 / y. 15.1 / MNUH / D of November 20, 1987 laying down the bases for calculating the market value of buildings expropriated for reasons of public utility. The result of this study shows that mapping is a very practical tool for identifying and materializing the impacts that a project may have on components of environment. The GIS revealed a potential disappearance of 1502 building spread over 867 parcels of land.

Plural Rationalities

The concept of agency is increasingly used in the literature on sustainability transitions. In this paper, we add to that discussion by arguing that the concept of rationality opens new avenues to theorizing relational agency in transitions toward a circular economy. To this end, we compare rationality conceptions from management (e.g., collaboration and competition) with critical theory perspectives on rationality (e.g., instrumental and communicative rationality). This leads us to develop a typology matrix for describing plural rationalities underpinning relational agency. We illustrate this typology using excerpts from an in-depth case study of an ongoing city-coordinated ecosystem that develops a smart technology-enabled urban area based on the principles of circularity. The first contribution of this interdisciplinary paper is to offer a rational perspective on theorizing the antecedents of relational agency in circular economy transitions, where communicatively rational action enables agency and change. Secondly, our paper contributes to the literature on circular cities through conceptualizing circular transition as simultaneous collaboration and competition. Thirdly, our paper introduces a dyadic perspective on rationality to the literature on coopetition and provides an operating space from which professionals can navigate, depending on the type of coopetitive situation.

Privately Owned

The water source of the people residing in Code Watershed is currently accessed from water wells, which are privately owned by most of the house. The urban area in the watershed is highly populated and its waste is disposed of into the ground, which contaminates groundwater. Therefore, an urban area located in a higher topography poses threats to the groundwater quality downstream. The research found that the groundwater in the lower part of Code Watershed was polluted because it received the waste discharge from the city upstream and, at the same time, had to deal with the existing pollution in it.

Having a major economic and social role, public transport is an important component in the process of sustainable development of a city. The paper aimed to study the public transport at metropolitan and regional scale evidencing how two major urban centers of Romania, Suceava and Boto?ani, connect via public transport with the rural settlements in their metropolitan areas. The metropolitan supply of public transport was analysed starting with publicly available data on the routes in 2014 for both Botoșani County and Suceava County, located in the North-Eastern side of Romania. The routes’ spatial disposition and daily frequency is analysed for road and rail public transport. The resulted mappings showed that road public transport is well distributed in the metropolitan territory for both urban centres, but there is still almost 4% of the rural population that does not have direct access to this public utility service. The rail public transport covers only a small amount of the studied area and it has a secondary role in supplying public transport services for the population because of the lack of investments that the entire rail sector suffered in Romania. The share of private cars has increased significantly, but the population’s need for mobility is not completely covered and this paper offers some recommendations for the improvement of the public transportation supply in Suceava-Boto?ani Urban Area.
