What Are Shelters Made Of In Urban Shantytowns In Paraguay? Brick, Cardboard, and Corrugated Iron Define the Landscape
In Asunción and other major Paraguayan cities, thousands of families live in precarious shelters constructed from a mix of salvaged materials and basic industrial products. These informal settlements, often located on steep hillsides or alongside major highways, face constant challenges from environmental extremes and a lack of formal infrastructure. This article examines the specific materials used in these shelters, the economic and environmental factors driving these construction choices, and the perspectives of the residents who inhabit them.
The landscape of urban poverty in Paraguay is visually defined by a distinct architectural palette. Driving through neighborhoods like La Chacarita in Asunción or the outskirts of Ciudad del Este reveals a patchwork of resilience and hardship. The materials used are not merely a matter of preference but are often the only viable option for families operating on the economic margins. Understanding these components provides a clearer picture of the daily realities faced by Paraguay's informal urban population.
The most common foundational element in urban shantytowns across Paraguay is the humble brick. While this might suggest a degree of permanence, the reality is often more complex and precarious.
* **Standard Clay Bricks:** These are frequently used for the lower courses of walls, providing a stable base. However, the quality can be highly variable, as many are produced in small, unregulated neighborhood factories.
* **Improvised "Tierra" Bricks:** In many cases, bricks are made on-site from a mixture of clay, sand, and sometimes organic waste like straw. These sun-dried bricks are a low-cost solution but are highly susceptible to disintegration during the heavy seasonal rains.
* **Cinderblocks:** In slightly more established settlements, concrete cinderblocks may be used. These offer greater durability but are still often paired with substandard mortar, leading to structural weaknesses.
A local community leader in the San Pablo neighborhood of Asunción, who requested anonymity for fear of eviction, described the cycle of building and rebuilding. "The brick is the base, but the rain is the enemy," he explained. "We build the walls as high as we can with what we have, but every year the storm comes, and we must repair what has fallen. The wall absorbs the water, and it crumbles." This constant battle against the elements means that even seemingly sturdy brick walls are often temporary shields rather than permanent structures.
Beyond the brick, the skeleton and skin of these shelters are most often formed by a combination of wood, corrugated iron, and a vast array of scavenged materials. The interplay between these elements defines the shelter's ability to provide basic protection.
Wood serves as the primary structural framework. It is typically sourced from discarded wooden pallets, old telephone poles, or planks pulled from construction sites.
* **Pallet Wood:** The abundance of wooden pallets from factories and markets makes them a prime building material. They are easily dismantled and provide the necessary frames for walls and roofs.
* **Pole and Stake Construction:** For more permanent-looking structures, thicker wooden poles are driven into the ground to create a sturdier frame. However, this wood is often untreated, making it vulnerable to termite infestation and rot over time.
The most iconic and ubiquitous roofing material is corrugated iron. It is favored for its relative durability, availability, and the ease with which it can be transported and assembled.
* **Galvanized Sheets:** These are the standard, providing a degree of waterproofing that is essential during the wet season. However, they are poor insulators, turning shelters into ovens under the intense Paraguayan sun and into rattling, cold chambers during cooler nights.
* **Improvised Canopies:** In many denser settlements, the space between corrugated iron roofs becomes a complex layering of additional scavenged materials. Plastic sheets, tarps, and even flattened oil drums can be found capping leaks or providing extra shade.
It is the infill and roofing where the true ingenuity and stark reality of these settlements become apparent. This is where the line between shelter and makeshift habitation is starkly visible.
* **Cardboard and Thick Plastic Sheets:** These are used extensively for interior walls, room dividers, and temporary roofing patches. A plastic shopping bag, meticulously cut and taped, can be the difference between a dry bed and a puddle of water.
* **Scavenged Metal and Tin:** Discarded pieces of sheet metal, often rusted and pitted, are used for everything from roofing to makeshift doors. In some areas, flattened gasoline cans are a common sight.
* **Reclaimed Wood and Wire:** Wire recovered from construction sites or scavenged from old furniture is used for lashing wooden frames together or creating rudimentary fences. Old billboard advertising canvases, while providing large surface areas for shade, are also highly flammable.
The reliance on these materials creates a landscape that is both poignant and practical. A single-story shack might have a roof of corrugated iron, walls made of a mix of brick and painted plastic sheeting, and a door repurposed from a discarded cabinet. The aesthetic is one of improvisation, where the primary goal is immediate shelter from the sun, rain, and wind, rather than structural longevity or thermal comfort.
The choice of materials is deeply intertwined with the economic reality of the residents and the specific environmental pressures they face. Poverty dictates the use of scavenged and low-cost items, while the climate dictates the functional limitations of those materials.
Paraguay experiences a climate with a pronounced dry season and a wet season, and shelters must withstand both extremes. The corrugated iron roof, while waterproof, does little to mitigate the heat. During the dry season, interiors can become stifling, leading to health issues related to heat stress. Conversely, during the cold winter nights, these same structures offer little insulation, forcing families to burn wood or coal indoors, which poses significant respiratory health risks. The intense sun also causes the materials to degrade faster, bleaching plastics and baking the dried mud bricks, which crumbles more easily.
The constant vulnerability to storms and flooding further exacerbates the problem. Heavy rains can quickly overwhelm the rudimentary drainage systems of these neighborhoods, turning dirt floors into mud and weakening the very brick foundations. A severe storm can undo months of careful construction, forcing families into a cycle of repair and rebuilding that consumes their limited financial resources. The materials are accessible, but the stability they provide is fragile.
