Abstract Coastal areas are natural spaces with a high economic and tourist potential due to their access to the sea; however, the municipalities of the Department of Córdoba located in these ecosystems have a low financial and administrative performance measurement, due to the difficulties they have in mobilizing their own resources and managing territorial planning. In this sense, the city-citizen relationship established in the urban construction processes in two coastal municipalities of the department is analyzed from the point of view of living as a diagnosis of the urban needs of these places. It was approached from a mixed approach with sequential explanatory design and the survey of urban imaginaries was applied with questions of subjective nature about the feeling-thinking of the population in their territory. The results allow affirming that the aesthetic niches in both municipalities are adequate for their inhabitants between what they like (beach-tourist potential) and what they dislike (deficit of infrastructure and public services). (lack of infrastructure and public services) of the place where their socio-cultural, economic and political practices are rooted. economic and political practices are rooted. Taking into account that the territorialization processes in this region have been slow, it is region have been slow, urban management is required to improve the quality of life of the inhabitants in their environment. the quality of life of the inhabitants in their environment.

Abstract With the rapid development of urbanization, the development and construction of new towns and new areas has become the main direction of urban expansion. On the contrary, the development of the old urban areas has been neglected and gradually fell into recession. In the new era, how to promote the new vitality of the old city and realize the double wheel drive between the old city and the new city has become an urgent research topic. Enning Road, located in the old urban area of Liwan, guangzhou, gathers the essence of Xiguan arcade building, but once became a typical example of the decline of old blocks. Through micro transformation, it not only protects the authenticity of the historical environment, but also promotes the development of the cultural tourism industry, realizes the regeneration of the historical and cultural blocks, and walks out a unique road to the revitalization of the historical and cultural blocks. Based on this analysis, the article puts forward policy suggestions to further improve the revitalization of historical and cultural blocks from the aspects of establishing a diversified participation mechanism, correctly handling the relationship between the protection and development of historical and cultural relics, and preventing violations of consumer rights and public interests.

Abstract Modern urban governance emphasizes the precise governance of the “short board” of urban governance, forming a mechanism of fine governance. In view of the historical basis and realistic structure of the differentiation of physical space at the block level and the diversity of life at the community level in modern cities, the short board of urban governance should be confirmed and solved through democratic participation based on the context of spatial differentiation and diversity of life, rather than through simple administrative urban planning, so as to form a corresponding structure consistent with rigid urban management. The vitality of a city lies in the construction of differentiated block space and diversified community autonomy. Therefore, the urban path of fine governance is fine governance based on public recognition. It should include the establishment of the concept of spatial differentiation and diversity of life, the construction of democratic relations among modern urban governance subjects, the transformation of urban planning to community planning, and the avoidance of destructive renewal and one-way material construction, go beyond the sports regulation of urban issues and apply the big data technology in modern urban governance.

Abstract The habitat unit in urban fringe is an important link to support regional biodiversity; due to the influence of urban system and agricultural system, most of them are semi natural, appeared with diverse types, small patches, scattered layout, and generally relying on low intensity farming activities. Export-oriented expansion of urban construction land and intensive agricultural production are prone to reduce the scale and quality of semi natural habitats in urban fringe areas; and the existing measures cannot effectively protect them. High natural value farmland management is an effective measure of the EU to protect semi-natural habitats related to agriculture and maintain regional biodiversity. Through combing the main points of high natural value farmland such as type definition, evaluation, identification, maintenance management, etc., this paper proposes the suggestions for optimization of small and micro semi-natural habitat protection in China: (1) strengthening the recognition of the value of small and microhabitats and related land use; (2) identifying small and micro-habitats that are conducive to the maintenance of biodiversity, and incorporating them in the overall protection of regional network; (3) combining the rigidity and flexibility of land use control, with the consideration of complex function demands; (4) Converging with the existing statutory planning to enhance the protection efficiency of small and micro habitats.

Abstract From the evidence obtained in the 2017 Chilean population census pyramid for the country scale, the question arises whether the population structure by age is replicated homogeneously at the subnational level or, on the contrary, it presents heterogeneous local characteristics based on age groups. For each of the third-level subnational units (n=346), the standard deviation of the different age classes was compared in relation to the national population pyramid. With these differences, the k-means method was used to identify eight groups of communes, and four demographic indicators were calculated. The results allow to affirm that the population structure by age and sex at the communal level presents heterogeneous characteristics. The analysis of territorial patterns identified groups of the aging population, households with active aging, transition to aging, adult population, men in terminal productive age, men in initial age, households with children under 15 years and households with children over 15 years.

Abstract This paper scrutinizes the way diversity is understood in urban zones and cities. It seeks to demonstrate that diversity is a consequence of the fragmentation of social interactions drawn from the blurring of the other in order to root out liberal subject, the one that holds political and social equality. In this sense, we propose looking once again at the city and public space from the perspective of its distances and social separation, as well as the recognition of social absences in what is called “plurality” that, nowadays, demands an interdisciplinary dialogue and creatively crafted methodological frames.
