periurbanas

Periurbanas, or peri-urban areas, are zones that lie at the interface between urban centers and rural hinterlands. They are characterized by a mix of land uses and residents, and by rapid change driven by urban expansion, population growth, and economic development. Periurbanas often experience a transition from agricultural to residential and commercial land uses, with scattered housing, informal settlements, and new infrastructure.

In these areas, governance is typically complex because multiple municipalities, regional authorities, and private actors influence land development, services, and planning. Access to housing is a major driver of growth, along with commuting patterns that link periurban zones to the city core. Infrastructure such as water, sanitation, roads, and electricity can lag behind demand, leading to service delivery gaps and greater vulnerability to environmental hazards.

Environmental impacts include conversion of agricultural land and ecosystems, increased flood risk, pollution, and reduced biodiversity. The fragmented governance and land tenure issues can complicate land management and risk mitigation. Socially, periurbanas may exhibit rising inequality, with new arrivals securing housing on the urban fringe while poorer residents occupy informal settlements on less secure land.

Policy approaches emphasize regional planning, coordination among jurisdictions, and the integration of urban and rural development objectives. Strategies include strengthening land management, extending services, promoting sustainable transport, and protecting agricultural land and ecosystems. The term is widely used in Latin America, Africa, and Asia, while English-language literature often uses peri-urban or periurban areas to describe these transitional zones.
