Distribution and structure of intertidal macrobenthic communities in the Zwin nature reserve, a lagoonal inlet consisting of marsh and tidal flat habitats, was investigated using univariate and multivariate analyses. Macrobenthos community structure was related to environmental characteristics and discussed in the framework of the implemented extension of the nature reserve.Based on explorative multivariate techniques, five different sample groups (SGs) were distinguished, which were, in general, located in different habitats of the Zwin nature reserve. The ecologically most important SGs consisted of the highest macrobenthic density, diversity and highest densities of Nereis diversicolor and Scrobicularia plana; these important prey species for wading birds and fish occurred in the deep tidal inlet channels. This habitat was characterized by fine to medium sand sediment and strong tidal currents, guaranteeing water renewal at each high tide. Other SGs were found in less and erratically submersed and thus stressed areas (i.e. tidal pond, salt pans and shallow flats). These assemblages were characterized by typical r-strategists (i.e. Capitella capitata and Polydora cornuta) and typical supralittoral, mobile species (i.e. Orchestia gammarellus and Collembola spp.). Being ecologically most important, the extension of wide, tidal creeks should be a prime target within the future development and management of the nature reserve.

Cities are an important resource for the socio-economic and regional development of the state. Urban development depends on resources, capital, labour force, which mobility from the impact of scientific and technological progress increases all the time. Resources don't belong largely to the concrete place anymore as it was before. That is why cities could think about the possibilities of increase of their attraction and competitiveness at the context of sustainable development. It means that one of the most important goals of the urban development and management is to create such kind of the urban environment which will be in line with the needs and requirements of the city inhabitants, which will be attractive for the foreign investors and tourists, which could compete with other cities. But the most important is that urban environment could give us all an opportunity to be active, participate and enjoy. The world practice shows that the use of the principles and instruments of the marketing for provision of sustainable urban development has positive impact on the socioeconomic and regional development of the state – it improves the investment environment, increases the rate of the economic investments, promotes business and tourism, improves the quality of education, increases welfare and mental development. The necessity of more detailed analysis of the importance of place marketing for sustainable urban development determines actuality of this research.

<em>Most planning authorities in developing economies are not effective due to poor urban and regional planning systems making it almost impossible to control urban development and management of urban areas, leading to the haphazard urban development and poor management bringing about disproportionate distribution of resources in terms of basic infrastructure. It is against this backdrop that this paper seeks to examine the effectiveness of the institutional and technical planning frameworks in terms of Urban Development and Management (UDM) in Jos metropolis Nigeriaby identifying the factors that determines the effectiveness of the urban governance and management as well as identify and examining the urban planning system towards ensuring an effective urban controlled development and management in Jos metropolis Nigeria. The research approach adopted is qualitative and quantitative with deductive-inductive reasoning. The strategy used is “mixed method” and the instruments employed were questionnaires, face-to-face interviews, case studies documents reviewed with planning authorities in Jos Metropolis, Nigeria. The quantitative data sets obtained were analysed using Spearman ranks correlation coefficient (rho) and the qualitative data were analysed using thematic and content analysis. Statistically, the results showed that the components of the institutions (UG) and technical (UM) all have very strong statistical correlation. Based on the study results recommendations are proffered to practitioners, academia and policy makers.</em>

The urban development and management challenges of the developing world are well documented in the literature. However, the global built environment landscape is undergoing rapid changes. These changes are steeped in three fundamental imperatives, which have serious implications for the developing world. These imperatives are population growth and rising urbanisation; environmental challenges, particularly climate change and the quest to embrace sustainability as a panacea; and advances in technological development. This paper discusses these three imperatives with the view to teasing out their implications for urban development and management in the developing world. Consistent with the literature, the paper establishes that most of the population growth and rising urbanisation are occurring in the developing world, particularly Africa and Asia, and although these phenomena have the tendency to increase economic density and promote both private and public investment in urban development, especially construction/housing and related infrastructure activities, there are and will be several problems with them. These include land tenure insecurity, lack of access to decent affordable housing and the threat of destruction to heritage sites. Furthermore, environmental challenges such as poor waste management, and climate change are and will remain pressing issues requiring the adoption of sustainability credentials because of legislative requirements, moral suasion, and value addition. Despite the potential disruptive nature of technology with respect to some aspects of the built environment, it is recognised that advances in technology are essential to the achievement of optimal urban development and management outcomes in the developing world. The paper, therefore, recommends better understanding of the socio-economic, cultural, and political forces underlying urban growth in the developing world, factoring in technology and sustainability in urban development and management, and collaboration among relevant actors, particularly government and the private sector, for optimal outcomes.
