Photo: <em>Carioca Waters<\/em>\/Reproduction<\/figcaption><\/figure>\n<p>The area surrounding today\u2019s Complexo da Mar\u00e9 was once a vast archipelago. Its islands formed channels that helped keep alive the sea that flowed through the area inhabited by the community. The waters of <a href=\"https:\/\/bit.ly\/2IVVjp1\">Guanabara Bay<\/a> stretched far inland, reaching what is now the Brazilian national health foundation (<a href=\"https:\/\/bit.ly\/2WRi6JK\">Fiocruz<\/a>). Within what is now Mar\u00e9, there was Pinheiro Island (currently the <a href=\"https:\/\/bit.ly\/41jsgDl\">Cadu Barcellos Ecological Park<\/a>), Inha\u00fama Hill (the <a href=\"https:\/\/rioonwatch.org\/?tag=morro-do-timbau\">Morro do Timbau<\/a> favela), the Inha\u00fama Cove (where today stand the micro-regions of <a href=\"https:\/\/bit.ly\/3fMPxFy\">Vila do Pinheiro<\/a>, <a href=\"https:\/\/bit.ly\/1Gd4bRb\">Vila do Jo\u00e3o<\/a>, and <a href=\"https:\/\/bit.ly\/3sZhWC0\">Conjunto Esperan\u00e7a<\/a>), and Apic\u00fa Beach (which used to be a large mangrove area between the <a href=\"http:\/\/bit.ly\/2HRzQwh\">Baixa do Sapateiro<\/a> and <a href=\"http:\/\/bit.ly\/2vcgKJM\">Praia de Ramos<\/a> communities). Mar\u00e9\u2014tide in Portuguese\u2014was, as its name suggests, an area between tides, located between the Faria River and Guanabara Bay\u2014thus, a naturally flooded and silted area.<\/p>\n<p>As human transportation occurred, according to the author, predominantly along its waterways, Mar\u00e9 had two ports: Maria Angu, at what is now Praia de Ramos; and one at the foot of Morro do Timbau, along what today is Rua Guilherme Maxwell (better known as Rua da Escola Bahia, near Passarela 7 on Avenida Brasil). This water-based characteristic is so striking in the territory that Timbau and Pinheiro, names of Tupi-Guarani origin, mean, respectively, \u201cbetween waters\u201d (<em>t\u00b4pau<\/em>) and \u201cspilled\u201d (<em>pi-i\u00eare<\/em>), according to <a href=\"https:\/\/bit.ly\/4nHLDPF\">records from the Mar\u00e9 Museum<\/a>.<\/p>\n<p>Due to this hydrographic profile, human settlement in Mar\u00e9 has always gone hand in hand with the development of its fishing culture. Making a living from fishing was so common that some Mar\u00e9 communities, such as Praia de Ramos and Conjunto Marc\u00edlio Dias, emerged from the settlement of fishing families. Fishing colonies, like those in <a href=\"https:\/\/bit.ly\/4nFsEoU\">Ramos<\/a> (founded in 1923), <a href=\"https:\/\/bit.ly\/4ob8qTH\">Pinheiro<\/a>, and Parque Uni\u00e3o, resist to this day and stand as living memories of this occupation.<\/p>\n<p>A resident of Parque Uni\u00e3o, born and raised there, <a href=\"https:\/\/bit.ly\/439l39C\">H\u00e9lio Ricardo<\/a> has been a fisherman in Mar\u00e9 for 40 years. He recounts how nature once dominated the region.<\/p>\n<blockquote><p>\u201cThis here [Mar\u00e9] used to be a small island. The mangrove has always been around. We used to have to come here [to Praia do Coqueirinho, next to the Fund\u00e3o BRT], wading chest-deep. Sometimes, when the tide went down, we walked with water up to our knees. That was 40, 45 years ago. Back then, we didn\u2019t need much netting to fish\u2014100 meters of net were enough to fill the boat.\u201d \u2014 H\u00e9lio Ricardo<\/p><\/blockquote>\n<figure id=\"attachment_81928\" aria-describedby=\"caption-attachment-81928\" style=\"width: 500px\" class=\"wp-caption alignright\"><a href=\"https:\/\/rioonwatch.org\/wp-content\/uploads\/2025\/10\/Record-of-the-old-Port-of-Maria-Angu-in-Ramos-shows-the-scale-of-the-beauty-that-surrounded-Mare.-Photo-Archive-Dona-Orosina-Vieira.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-81928\" title=\"Record of the old Maria Angu Port in Ramos shows the beauty that surrounded Mar\u00e9.

We\u2019d come back with 250, 300 swordfish. We\u2019d catch the ones we called &#8216;cachorro,&#8217; the big ones. There were so many of the small ones that we didn\u2019t bother bringing them; we\u2019d just throw them back into the water. I had my shrimp net. Wow! Eight shrimp added up to a kilo! Sometimes we\u2019d catch two boxes of them, real sardines. There was catfish too. There was a time when bluefish came in, and a time when weakfish came along with the croaker. Even snook would end up in the net.\u201d \u2014 Carlos Lopes<\/p><\/blockquote>\n<p>A centuries-old tradition in the area, fishing gradually changed over the second half of the last century. The availability of fish started to decline due to multiple interventions that harmed the <a href=\"https:\/\/bit.ly\/4kMUw8c\">health of Mar\u00e9\u2019s waterways<\/a>. These interventions compromised not only the practice of traditional fishing but also the community\u2019s very knowledge of the waters that weave this area together.<\/p>\n<h3>A Portrait of Mar\u00e9\u2019s Hydrography<\/h3>\n<p>Complexo da Mar\u00e9 is located <a href=\"https:\/\/bit.ly\/4gYaYlC\">between the sub-basin of Cunha Canal and the sub-basin of Ramos River<\/a>, with its main waterways being the Fund\u00e3o Canal\u2014running parallel to the <a href=\"http:\/\/bit.ly\/2MmBnPt\">Linha Vermelha<\/a> expressway\u2014and the <a href=\"http:\/\/bit.ly\/2xZB7eg\">Cunha Canal<\/a>, which crosses <a href=\"https:\/\/bit.ly\/2TylshE\">Avenida Brasil<\/a> near the <a href=\"http:\/\/bit.ly\/2YoSrKr\">Manguinhos<\/a> group of favelas. The Fund\u00e3o Canal, an artificial waterway roughly six kilometers long, was created by the former archipelago&#8217;s infilling giving rise to University City, now Fund\u00e3o Island. It meets the Cunha Canal near Linha Vermelha, at the back of the community, close to Ponte do Saber bridge. Nearly all the sewage outlets from the community and from much of the North Zone of Rio flow into Fund\u00e3o Canal.<\/p>\n<figure id=\"attachment_81915\" aria-describedby=\"caption-attachment-81915\" style=\"width: 2560px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/rioonwatch.org\/wp-content\/uploads\/2025\/10\/One-of-the-sewage-outlets-that-flow-from-Mare-into-the-Fundao-Canal-where-the-Linha-Amarela-and-Linha-Vermelha-meet-before-emptying-into-Guanabara-Bay.-Photo-Amanda-Baroni-scaled-1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-81915 size-full\" title=\"On the left bank, sewage outlets flow from Complexo da Mar\u00e9 into the Fund\u00e3o Canal, where the Linha Amarela and Linha Vermelha meet, before emptying into Guanabara Bay.

There\u2019s one at Jet Clube and [another] at the Ramos [Fishing] Colony.

S\u00e9rgio Ricardo, director of the <a href=\"https:\/\/bit.ly\/3DxyLFD\">Living Bay Movement<\/a>, explains.<\/p>\n<blockquote><p>\u201cThis is a problem with Brazilian engineering. For over 30 years now, <a href=\"https:\/\/bit.ly\/43zNiyz\">river renaturalization<\/a> has been underway everywhere else in the world. It&#8217;s something that&#8217;s <a href=\"https:\/\/citychangers.org\/daylighting-rivers\/\">been discussed<\/a> since the <a href=\"https:\/\/bit.ly\/4qzgUWQ\">1992 Earth Summit<\/a> while here we\u2019ve continued to bury and straighten rivers. We have to work with official sources, but through a dialogical process. Some rivers have an official name, but in older communities, fishermen don\u2019t recognize them by that name. They know them by others\u2014usually Indigenous ones. The renaturalization of rivers and their original courses represents a different concept, an environmental one. Here [in Brazil, what\u2019s followed] is engineering without ecology, a hydraulic concept. The same is done with Indigenous issues. How many peoples existed? No one knows. The Fund\u00e3o Canal, for example, now runs along the Linha Vermelha [expressway]. But did the [original] river really follow that path?\u201d \u2014 S\u00e9rgio Ricardo<\/p><\/blockquote>\n<p>Over the years, housing policies aimed at \u201cprogress\u201d did not merely stop at eliminating, filling in, or altering Mar\u00e9\u2019s waterways. These actions profoundly affected the community\u2019s collective memory and disrupted local ecosystems. Today, many residents experience a sense of disconnection from their natural heritage\u2014a result of interventions that date back to the early 20th century.<\/p>\n<h3>The Process of the Degradation of Mar\u00e9\u2019s Waters<\/h3>\n<p>Between 1908 and 2012, the region of the Cunha Canal sub-basin <a href=\"https:\/\/bit.ly\/3Wrb5g9\">underwent numerous interventions<\/a> due to its flood-prone nature. Most of these works took place either within or around Complexo da Mar\u00e9\u2014such as the landfills used to build the former Manguinhos Airport and for the construction of Avenida Brasil (beginning in the 1940s), the infilling of the islands that once existed in Fund\u00e3o in 1949, and the <a href=\"https:\/\/bit.ly\/ProjectRio\">Project Rio<\/a> fill carried out from 1979 to 1980, in the area where Mar\u00e9\u2019s stilt houses once stood.<\/p>\n<p>Aiming to address the issue of housing in favelas, Project Rio carried out a massive land reclamation initiative in the Vila do Pinheiro area. A total of <a href=\"https:\/\/bit.ly\/4o2lTNw\">69 hectares of Guanabara Bay<\/a> were altered to make way for the construction of 2,300 houses. However, the housing initiative was not accompanied by effective <a href=\"https:\/\/bit.ly\/2QQR0xh\">sanitation<\/a> planning, which led to waste being dumped directly into Mar\u00e9\u2019s canals and, consequently, into Guanabara Bay.<\/p>\n<p><em>Seu<\/em> H\u00e9lio laments how Mar\u00e9\u2019s canals and Guanabara Bay\u2014the main outlet for all these waterways\u2014have become so severely degraded.<\/p>\n<blockquote><p>\u201cThere used to be about 100 fishermen here. We\u2019d head out early in the morning, around six, and by noon we\u2019d be back with four or five [full] trays. That was some 100, 150 kilos of fish. There was anchovy, true sardine [a term for healthy fish], what we call maromba; shrimp, the big kind, the real one; weakfish, snook, stingray\u2026 There was such abundance. We once caught over 300 kilos of stingray [in these waters]. [Up until that time, the late 1970s,] you could make a living. I raised my kids on fish, selling fish. But not anymore. Before, there was sand here, but [now everything\u2019s] turned to mud. [These days,] we still catch some [fish], but much less [because of the pollution].\u201d \u2014 H\u00e9lio Ricardo<\/p><\/blockquote>\n<p>All these landfills directly and significantly affected Mar\u00e9\u2019s canals. To ensure these projects\u2019 feasibility, the works required the construction of artificial drainage channels for the floodable lands\u2014which, in turn, started carrying all the domestic waste from Mar\u00e9\u2019s communities into Guanabara Bay. In this way, the biodiversity of Mar\u00e9\u2019s waters gradually gave way to sewage and pollution.<\/p>\n<p>But the neglect resulting from the lack of planning and public investment in Mar\u00e9\u2019s waterways goes beyond landfilling. In the second half of the last century, the rivers in the Cunha sub-basin underwent aggressive interventions. Once meandering and sinuous, these rivers were straightened, channeled, filled in, or covered by the urban grid in an effort to <a href=\"https:\/\/bit.ly\/2RNTfSu\">control flooding<\/a>.<\/p>\n<figure id=\"attachment_81922\" aria-describedby=\"caption-attachment-81922\" style=\"width: 1600px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/rioonwatch.org\/wp-content\/uploads\/2025\/10\/Current-state-of-Cunha-Canal-near-the-Salsa-e-Merengue-community.-Photo-Amanda-Baroni.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-81922 size-full\" title=\"Current state of Cunha Canal near the Salsa e Merengue community.

This project altered the Cunha Canal\u2014a natural waterway that, in addition to being lined with concrete, was extended due to the merging of the Faria and Timb\u00f3 Rivers. Today, the Faria-Timb\u00f3 is a straightened, concreted, and extremely polluted river.<\/p>\n<p>Beyond that, interventions that could potentially improve life in the community still struggle to become reality. In the late 1980s, a project for the construction of the <a href=\"https:\/\/bit.ly\/4nHjdFi\">Mar\u00e9 Perimeter Drainage System<\/a> aimed to treat the sewage running through what is now Rua do Val\u00e3o. However, as <em>Seu<\/em> Helio recalls, the project never left the drawing board.<\/p>\n<blockquote><p>\u201cThe sewage that came [and still comes] from <a href=\"https:\/\/bit.ly\/38BRUa3\">Olaria<\/a> and <a href=\"https:\/\/bit.ly\/34AR8ac\">Penha<\/a> was supposed to be treated before being released into the Cunha Canal. An old leather-tanning company that\u2019s since closed down, in Penha, polluted a lot because of the chemicals it used. The Parque Uni\u00e3o street market was supposed to be moved there [to Rua do Val\u00e3o], but that never happened. The project never left the drawing board. And all that [sewage from the area] ends up here in Guanabara Bay. The tannery is no longer around, but there are still many industries [in Penha] that dump everything into those open drains. And you can see it [when you go by] on Avenida dos Campe\u00f5es [in Ramos]; it comes down Rua Teixeira de Castro, near Passarela 10, across from Parque Uni\u00e3o, all the way to the Cunha Canal.\u201d \u2014 H\u00e9lio Ricardo<\/p><\/blockquote>\n<p>Today, the waters that flow through Mar\u00e9 suffer the impacts of all these changes that, over time, have radically transformed the original landscape.

The dredging allowed mangrove vegetation to naturally reappear in Mar\u00e9\u2019s landscape. The improvements lasted a mere two years, however, due to a lack of maintenance, showing that the problem cannot be solved in isolation. Lopes vents his frustration over the inefficiency of the effort.<\/p>\n<blockquote><p>\u201cThey only dredged a small stretch, from the Pinheiro bridge to Parque Uni\u00e3o. That&#8217;s it! If you go to Fund\u00e3o, you\u2019ll see the mountain of mud. The section that needed dredging wasn\u2019t dredged. They should have come dredging all the way here to Ponta do Arass\u00e1. They should have started from the canal coming from Manguinhos. The Pinheiro [which receives these tributaries] is unmanageable. [To navigate] There, the fisherman has set times to leave and arrive and has to be in the right spot. It\u2019s a very restricted area for navigating a boat. A large vessel? Forget it. It won\u2019t get through\u2014too shallow, too much mud. And it\u2019s not just mud, it\u2019s filth. Why do they keep dredging the Port of Rio? Because the sea naturally silts up the river, so dredging is always necessary. The same thing would have benefited fishermen here. The water flow to and from these neighborhoods would be much better because we&#8217;d have proper outflow here. You can\u2019t pour a bucket of water into a teacup.

And it wasn\u2019t restricted to Fund\u00e3o Island. The <a href=\"https:\/\/www.reuters.com\/world\/americas\/dozens-dead-stingrays-found-brazil-beach-2023-04-11\/\">news went global<\/a>, and to this day we still haven\u2019t gotten an explanation for why these rays died. Another case was the near-extinction of the swordfish, which disappeared from the Bay for almost three years [between 2022 and 2025]. Most fishermen were worried because, although its commercial value is low, it\u2019s in demand\u2014it\u2019s tasty. Nowadays, catching one is almost like winning a trophy. This happens because of oil spills from ship hold washing, by companies operating in the Bay. They&#8217;re the ones that profit the most from nature and that pollute the most. And this is the fishermen\u2019s big concern: which species will be next? Are we heading toward our end? Is there no way to save [our local nature]?\u201d \u2014 Branca<\/p><\/blockquote>\n<p>This reality affects Mar\u00e9\u2019s population and their connection to activities such as fishing\u2014a cultural heritage that has always intertwined identity and <a href=\"https:\/\/bit.ly\/3w65Arn\">food security<\/a> in the community\u2019s life. Thinking about the rivers is, at the same time, thinking about a single Rio (its name evoking both city and river). Environmental policies need to move in tandem with others, such as education, sanitation, and energy policies. The problems facing Mar\u00e9\u2019s waters, therefore, cannot be addressed in isolation.<\/p>\n<blockquote><p>\u201cPeople want to [complain] that there\u2019s no fish, there&#8217;s no fish. Of course [there&#8217;s no fish]! Everything\u2019s polluted! Fish go where it\u2019s cleaner! Are they going to stay where there\u2019s pollution? Where there\u2019s no oxygen? When man destroys the last tree in the forest, wipes out all the rivers, pollutes, and eliminates all the fish in the sea\u2014that is, our entire ecosystem\u2014he&#8217;ll see that you can&#8217;t eat money.\u201d \u2014 H\u00e9lio Ricardo<\/p><\/blockquote>\n<p><em>About the author:\u00a0<a href=\"https:\/\/bit.ly\/3p94eas\" target=\"_blank\" rel=\"noopener\">Amanda Baroni Lopes<\/a>\u00a0has a degree in journalism from Unicarioca and was part of the first Journalism Laboratory organized by Mar\u00e9\u2019s community newspaper\u00a0<a href=\"http:\/\/bit.ly\/2YfGMc5\" target=\"_blank\" rel=\"noopener\">Mar\u00e9 de Not\u00edcias<\/a>.
