Gentrification has been changing the landscape of many urban centers around the world. In the big cities, this phenomenon is visible through the revitalization of previously degraded areas, usually accompanied by an increase in the cost of living and displacement of low-income residents. Real estate speculation is one of the main driving forces, attracting investors who see these spaces as profit opportunities, radically changing the social and economic dynamics of these places. The term "gentrification" was coined by British sociologist Ruth Glass in the 1960s to describe the replacement of working-class populations by middle and upper classes. She observed changes in neighborhoods in London, such as Islington, where wealthier classes replaced traditional residents and caused an increase in housing costs. According to Glass, this phenomenon produces cultural, social, and economic changes that reshape the original dynamics of urban neighborhoods. Examples of this phenomenon can be seen in cities like New York, Berlin, and São Paulo, where traditional communities are forced to relocate due to the appreciation caused by new real estate projects. Impacts of gentrification Gentrification is a process of urban transformation that occurs when areas previously belonging to less valued neighborhoods are revitalized, usually through real estate investments, which attracts a wealthier population to the region. Although the process of gentrification can bring improvements in terms of infrastructure, it can also cause several negative impacts, especially for the original residents of these areas. 1. Displacement of original residents One of the most significant impacts of gentrification is the forced displacement of low or middle-class residents. With the arrival of wealthier new residents, the cost of living in the area rises, leading to an increase in rents and property prices. 2. Loss of cultural identity As areas become more attractive to a distinct population, cultural changes often occur. Restaurants, shops, and public spaces are transformed to cater to the tastes and preferences of the new class, while traditional businesses and cultural entities of the original community are replaced. This can result in the loss of cultural traditions and a sense of belonging, profoundly altering the community's identity. 3. Increase in social inequalities Gentrification tends to deepen social inequalities. New infrastructure and rising property values often benefit the upper classes more, while poorer residents become further marginalized. These impacts can exacerbate socioeconomic divisions and make the city more segregated, with high-income areas becoming more separate from low-income areas. 4. Increase in the cost of living The arrival of high-class companies and consumers raises the cost of living for the entire area. Food, transportation, services, and other consumer goods become more expensive, making daily life more difficult for those who were used to the lower prices of the old areas. This increase in the cost of living is one of the main reasons why original residents are forced to leave. The lack of urban planning as an aggravating factor The absence of efficient urban planning and an effective master plan favors gentrification. Without regulations that ensure the permanence of vulnerable populations, the revitalization of urban areas ends up benefiting only the private sector. The lack of investments in affordable housing and access to essential services pushes low-income residents to peripheral regions, increasing travel time and hindering their integration into the city. Right to the city and access to housing Diverse authors have dedicated themselves to the theme, such as French philosopher Henri Lefebvre, Brazilian geographer Milton Santos, and urban planner Ermínia Maricato. Lefebvre advocates for the active participation of the population in the production of urban space and criticizes the private appropriation of public goods. Milton Santos addresses the commodification of cities, arguing that urban planning should prioritize collective well-being rather than just economic interests. Ermínia Maricato highlights the importance of housing policies to avoid social exclusion and ensure dignified housing for all citizens. The City Statute and its strategies to combat gentrification The City Statute, established by Federal Law No. 10.257/2001, sets guidelines for more inclusive urban development. Among its strategies, the social function of property, land regularization, and democratic management tools, such as the Master Plan, stand out. Measures such as progressive property tax and the allocation of areas for social housing are essential to mitigate gentrification and guarantee the right to the city for all. Paths to mitigate gentrification To reduce the impacts of gentrification, it is necessary to strengthen urban planning legislation and ensure that master plans encompass affordable housing. Measures such as the regulation of the real estate market, incentives for social housing, and the expansion of public services in central and peripheral areas can balance urban growth. Only with inclusive planning will it be possible to build fairer and more accessible cities for everyone.
