Modelo Económico

A Região Metropolitana do Cariri (RMC), sul do estado do Ceará, instituída em junho de 2009, é composta por 9 municípios que apresentam diferentes e consideráveis índices de crescimento populacional e correlatos níveis de expansão urbana e ocupação de áreas outrora classificáveis como ambientalmente conservadas, dotadas de significativa geodiversidade. Em que pese sua importância socioeconômica no Estado e o fato de se apresentar como uma importante região cearense, um quadro complexo de problemáticas ambientais vem se estabelecendo, pari passo ao seu crescimento econômico e urbanístico, colocando em risco a manutenção ambiental de diversos patrimônios naturais reconhecidos, bem como a sustentabilidade do modelo econômico estabelecido e em desenvolvimento. Nesse contexto, o objetivo principal desse trabalho é apresentar e discutir elementos centrais sobre o meio ambiente e sua sustentabilidade na RMC, apontando caminhos de reversão do quadro de degradação socioambiental estabelecido. Metodologicamente, a pesquisa desenvolvida até aqui baseou-se em criteriosos levantamentos bibliográfico e cartográfico, com ênfase nas temáticas apresentadas e na área de estudo, a RMC. As informações coletadas nesta etapa apoiaram a realização de levantamentos de campo exploratórios na região e a verificação de 5 (cinco) grupos principais de impactos ambientais, ocorrentes sob diferentes formas e intensidades nos 9 municípios.Palavras-chave: Análise Ambiental; Impactos Ambientais; Região Metropolitana; Desenvolvimento Sustentável; Geodiversidade. ABSTRACTThe Metropolitan Region of Cariri, southern of Ceará state, established in June 2009, is composed of 9 municipalities that present different and significant levels of population growth and related levels of urban expansion and occupation of areas formerly classified as environmentally conserved, with significant geodiversity. Despite its socioeconomic importance, in the state and the fact that it presents itself as an important region of Ceará, a complex set of environmental problems has been established, pari passso to its economic and urban growth, putting at risk the environmental maintenance of several recognized natural heritage, as well as the sustainability of the established and developing economic model. In this context, the main objective of this work is to present and discuss central elements about the environment and its sustainability in the RMC, pointing out ways of reversing the established framework of social and environmental degradation. Methodologically, the research developed so far has been based on careful bibliographical and cartographic surveys, with emphasis on the themes presented and the area of study, the RMC. The information collected at this stage supported exploratory field surveys in the region and verification of 5 main groups of environmental impacts, occurring under different forms and intensities in the 9 municipalities.Keywords: Environmental analysis; Environmental impacts; Metropolitan Region; Sustainable development; Geodiversity. RESUMENLa Región Metropolitana de Cariri (RMC), estado sureño de Ceará, establecida en junio de 2009, está compuesta por 9 municipios que tienen tasas de crecimiento demográfico diferentes y considerables y niveles correlacionados de expansión urbana y ocupación de áreas anteriormente clasificadas como conservadas ambientalmente dotado de una importante geodiversidad. A pesar de su importancia socioeconómica en el Estado y el hecho de que se presenta como una región importante de Ceará, se ha establecido una imagen compleja de los problemas ambientales, así como su crecimiento económico y urbanístico, poniendo en peligro el mantenimiento ambiental de varios patrimonios naturales reconocidos. así como la sostenibilidad del modelo económico establecido y en desarrollo.

Mediterranean regions have experienced a shift from accelerated urban growth typical of a post-industrial phase to a more recent spatial delocalization of population and economic activities reflecting discontinuous settlement expansion, land take, and the abandonment of cultivated areas around central cities. On the basis of a comprehensive analysis of land-use, settlement, and demographic indicators, the present study explores urban growth and population density over a sufficiently long time period in a metropolitan region of Southern Europe (Rome, Italy). Local-scale population trends were compared with the evolution of the primary sector (workers in agriculture, number of farms, cultivated land) between 1951 and 2011. Our results indicate non-linear growth waves alternating compact and discontinuous expansion shaping fringe land. The future development of metropolitan regions is increasingly dependent on the relationship between urban diffusion and economic viability of peri-urban agriculture. Crop abandonment and land take rates increase in local contexts where peri-urban agriculture rapidly declines. Policies managing ex-urban development and promoting the recovery of fringe soils are increasingly required to contain the expansion of dispersed settlements and preserve relict agricultural systems from land conversion to urban use.

Contemporary urbanization in the Pearl River Delta (PRD) Urban Agglomeration is the epitome of China’s urbanization process as the PRD is the first fastest growing metropolitan region of China. Here, we mapped and quantified the spatiotemporal dynamics of urban expansion for seven major cities in the PRD between 1980 and 2015, using remotely sensed data integrated with landscape metrics, urban growth form, and rank clocks. Results showed that rapid land urbanization occurred in all the seven cities since the execution of reform and opening up, with the annual increase rate ranging from 8.1% to 11.3% among cities, suggesting a relatively equal level of urbanization within the PRD. Socioeconomic drivers underlying urban expansion in Guangzhou, Shenzhen, and Zhuhai can be characterized as “top–down” mechanisms led by the municipal government, while those in Foshan, Jiangmen, Dongguan, and Zhongshan are “bottom–up” ones from low–level administrative organizations. The trajectory of urban expansion in Shenzhen conformed to the diffusion–coalescence urban growth hypothesis in terms of temporal evolution of landscape metrics and urban growth types. This is related to the fact that Shenzhen, the first special economic zone established by the Chinese government, was the first mover of urbanization in China and functioned under the umbrella of a robust socialist market economy relative to a highly centralized planned economy for other cities. The changes of Shenzhen in rank order in terms of both urban population and urbanization area were the largest, exemplifying its evolution from a small fishing village to a metropolis. Furthermore, we found that moving up in the rank order in terms of land use efficiency of wealth creation over time for all cities was accompanied with rank clocking up of population per area (crowd). How to balance trade–offs between the benefits and costs of urbanization is the challenge faced by the urban agglomeration.

O ordenamento e planejamento territorial dos municípios vêm sofrendo intensas e profundas mudanças, seja pela imposição das forças produtivas e do capital, ou ainda pela necessidade de se adotar novos arranjos territoriais que atendam determinadas necessidades e particularidades locais, trazendo na sua esteira transformações de ordem socioeconômicas e ambientais, levando a vários tipos de investimento em planejamento com abordagens diferenciadas. O último processo de planejamento da Região Metropolitana de Belo Horizonte, qual seja, o Plano Diretor de Desenvolvimento Integrado da Região Metropolitana de Belo Horizonte (PDDI-RMBH, 2009/2011), e o seu respectivo Macrozoneamento (MZ-RMBH, 2014), apontaram para a evidenciação da ocorrência de alguns processos socioespaciais desencadeados a partir de ações governamentais estruturantes, como é o caso do município de Confins, que já alterou toda sua legislação específica para estabelecer que o perímetro urbano, tal como definido no Plano Diretor vigente (Lei Complementar nº 012/2009), corresponde à totalidade das divisas municipais. Transformou, pois, todas as áreas/zonas rurais em áreas/zonas urbanas ou de expansão urbana. Buscou-se com esse estudo entender em que medida esse processo realizado em Confins foi derivado de disputas entre os vários interesses implicados na formação e no planejamento da Metropolitana de Belo Horizonte. A justificativa do trabalho consistiu na importância de, por meio do estudo e análise dos efeitos desse processo de territorialização do município de Confins, jogar luz sobre o papel do Aeroporto (AITN), da pressão imposta pela implantação da Cidade Administrativa e do Vetor Norte, desembocando, em tese, na supressão dos espaços rurais, e, via de consequência, na produção dos correlatos espaços urbanos.

The last planning process of the Metropolitan Region of Belo Horizonte, namely the Integrated Development Master Plan of the Metropolitan Region of Belo Horizonte (PDDI-RMBH, 2009/2011), and its respective Macrozoneamento (MZ-RMBH), pointed to The evidence of the occurrence of some socio-spatial processes triggered by structural governmental actions, as is the case of the municipality of Confins, which has already changed all its specific legislation to establish that the urban perimeter, as defined in the current Master Plan (Complementary Law No. 012 / 2009), corresponds to the totality of the municipal currencies. It has thus transformed all rural areas / areas into urban areas or areas of urban expansion. This study sought to understand to what extent this process carried out in Confins was derived from disputes between the various interests involved in the formation and planning of the Metropolitana de Belo Horizonte. The justification of this work was the importance of studying the effects of this process of territorialization in the city of Confins, to shed light on the role of the Airport (AITN), the pressure imposed by the implementation of the Administrative City and the North Vector, Leading to the suppression of rural spaces, and consequently, in the production of related urban spaces.

<p>O presente estudo compreende um levantamento das principais implicações geomorfológicas derivadas da mineração na Região Metropolitana do Recife - RMR, tendo como objetivo, apontar as principais alterações geomorfológicas delas derivadas e correlaciona-las com os riscos que podem trazer a sociedade. Para isso, foram realizados levantamentos bibliográfico, cartográficos; trabalhos de campo e geoprocessamento para a confecção das cartas temáticas. O que se observa na RMR é que a expansão urbana desordenada tem avançado em direção as áreas de extração de agregados da construção civil e, com isso, gera conflitos socioambientais. Verificou-se que a atividade mineira gerou passivos ambientais que levaram a intensa instabilidade dos sistemas ambientais nas áreas de exploração, com potencialização dos processos erosivos locais e retrabalhamento das superfícies morfológicas predominantes, pondo em risco a população residente. Associados a tais problemas, emergem os conflitos socioambientais. O que se observou foi à extrema necessidade de se repensar e planejar as atividades de mineração na RMR, com vistas a minimizar os conflitos, recuperar as áreas degradadas e evitar/minimizar novos processos de degradação ambiental. Tais ações demandam um esforço coletivo da sociedade e do poder público no sentido de planejar as atividades desenvolvidas no espaço urbano metropolitano. </p><p><strong>Abstract </strong></p><p>This study comprehends a compilation of the main geomorphologic implications derived by the mineral activity in the Metropolitan Region of Recife. It aims at pointing out the main geomorphologic alterations and correlating the risks that might be brought to society. In order to achieve our goals, we made a review of literature and maps as well as field research and geoprocessing to the confection of theme letters. We could observe that in MRR there is a disordered urban expansion that has been advancing to areas of building aggregate extraction, then generating socio-environmental conflicts. We verified that the mineral activity generated environmental passives that led to intensive instability of the environmental systems in the areas of exploration. Due to the potentialization of local erosion and reworking of predominant superficial morphology, there is a risk for the population of residents. Associated to those problems, the socio-environmental conflicts emerge. We verified the extreme need to rethink and plan the mineral activity in MRR, so that the conflicts might be minimized and to recover the degraded areas and avoid/minimize new processes of environmental degradation. Such actions demand a collective effort by the society and the government in order to plan the activities developed in the urban metropolitan region.</p><p><strong> </strong></p><p><strong>Key words</strong>: Data survey, impacts, mining, degradation, geoprocessing</p>

The municipality of Marituba, Metropolitan Region of Belém - RMB, has suffered environmental impacts due to irregularities in the landfill operation implemented in 2015, which triggered social impacts perceived by all the population, including neighboring municipalities, such as Ananindeua and Belém Protests were carried out by the Movement Outside the Garbage that is constituted by the dwellings of the surrounding neighborhoods to the place where the embankment is located, of owners of commercial activities linked to the tourism and Non Governmental Organizations that interrupted several times the transit of the main route that interconnects the seven municipalities of the RMB and the entrance of the embankment, in order to draw the attention of the municipal public power to the problems that the population would have been facing ever since. From this, the following questions arose: What social impacts would people be making in these protests? Would such problems be directly related to the activities carried out in the landfill? And finally, what are the actions of the public authority and the company that manages the enterprise in the management of these social impacts? The relevance of this study concerns not only the identification of social impacts considering the fragility of this approach in the Environmental Impact Studies and concomitantly in the Reports of Environmental Impacts, but also, from the point of view of the debate about the licensing process of enterprises of this nature and employment and the need for the joint use of environmental and urban policy instruments, considering that RMB municipalities have not yet used sustainable alternatives for the reduction of solid waste produced in their territories, as well as the reduction of environmental impacts caused by dumps , and in the case of Marituba, of the landfill that operates outside the standards established by the Brazilian Association of Technical Standards - ABNT, which is responsible for the management and treatment of solid waste and the National Policy on Solid Waste - PNRSN.

Urbanization is spreading across the world and beyond metropolitan areas. Medium-sized cities have also undergone processes of accelerated urban expansion, especially in Latin America, thanks to scant regulation or a complete lack thereof. Thus, understanding urban growth in the past and simulating it in the future has become a tool to raise its visibility and challenge territorial planners. In this work, we use Markov chains, cellular automata, multi-criteria multi-objective evaluation, and the determination of land use/land cover (LULC) to model the urban growth of the city of Temuco, Chile, a paradigmatic case because it has experienced powerful growth, where real estate development pressures coexist with a high natural value and the presence of indigenous communities. The urban scenario is determined for the years 2033 and 2049 based on the spatial patterns between 1985 and 2017, where the model shows the trend of expansion toward the northeast and significant development in the western sector of the city, making them two potential centers of expansion and conflict in the future given the heavy pressure on lands that are indigenous property and have a high natural value, aspects that need to be incorporated into future territorial planning instruments.

Urban growth concept has dragged the attention of several scholars of different fields of study for decades. Urban growth refers to expansion of urban centres in size due population growth, which hiked the number of buildings in urban centres around the world. The finding of the paper indicate that Gombe Metropolis expanded by (85 hectares) each year from 2000 to 2010 and the expansion of Gombe Metropolis occur in all direction. The rate at which Gombe Metropolis expand grown to (203 hectares) each year from 2010 up to date. Therefore, the rate at which Gombe metropolis expanded increases by 138% from 2010 to date and how number of markets increases to 16 currently from 12 in the year 2010. This paper study the Impact of urban growth on market in Gombe Metropolis. Coordinate of markets of existing markets was collected. For second set of data used in this paper i.e. secondary data which include map of Gombe metropolis, related journals, text books, published and unpublished document, and Newspaper were consulted. The data generated from questionnaire administration were analysed using tables, graphs and charts. Satellite images showing how urban growth is taken place in Gombe Metropolis were also analysed. The study examines the impact of urban growth on Gombe Metropolis markets activities over the period of study. The findings of the study indicate emergence of new markets in the study area over the years of study as a result of urban expansion that occur in Gombe Metropolis. It also indicated that the new established markets were located in areas where urban growth take place in study area and these new markets are patronized by people within the environment or vicinity of the markets. Most of the newly emerged markets are located at the periphery of the town where urban expansions occur rapidly.
