NITERÓI, Brazil, Oct 20 (IPS) – Homes with balconies going through the road or the encompassing hills, when they aren’t hidden behind excessive partitions, replicate a neighborhood the place folks reside on the shore of a lagoon however reject the panorama it gives.
Piratininga, a 2.87 sq. kilometer coastal lagoon within the southern a part of the Brazilian metropolis of Niterói, started to vary after a number of many years of uncontrolled city development with no look after the pure environment, in what has develop into a neighborhood of 16,000 inhabitants.
Rubbish, polluted water, building particles and dangerous odors harm the panorama and the standard of life that’s sought when selecting a lagoon and inexperienced hills as a spot to construct a year-round or weekend residence.
The collected sludge on the backside of the lagoon is 1.6 meters thick, on common, ensuing from each air pollution and pure sedimentation.
“That is what explains these homes that flip their backs to the lagoon,” defined Dionê Castro, coordinator of the Sustainable Oceanic Area Program (PRO Sostenible) of town authorities of Niterói, a municipality of 482,000 folks separated from town of Rio de Janeiro solely by Guanabara Bay.
Oceânica is among the 5 administrative zones of the municipality, domestically referred to as areas, which incorporates 11 neighborhoods within the southern half, on the open coastline, in distinction to others on the shore of the bay or inland areas with out seashores. With two lagoons and a part of the Atlantic Forest nonetheless preserved, the realm stands out for its nature.
PRO Sostenible, which was based in 2014, seeks to revive environmental programs and to make sure higher and extra sustainable urbanization within the space. Its actions are based mostly on a systemic strategy and nature-based options.

Pure clean-up of the water
This system’s flagship venture is the Orla Piratininga Alfredo Sirkis Park, which pays homage to a pacesetter of the environmental motion, former nationwide lawmaker and former president of the Inexperienced Celebration, in addition to journalist and author, who died in 2020.
The park, recognized by its acronym POP, has the mission of recovering and defending the ecosystems related to the Piratininga Lagoon, along with fostering a way of belonging to the atmosphere and its environment. Because of this, the participation of the native residents in all levels of the venture has been and continues to be a primary precept.
It includes an space of 680,000 sq. meters, the most important in Brazil in nature-based options initiatives, with 10.6 kilometers of bicycle paths, 17 leisure areas and a 2,800 sq. meter Ecocultural Heart.
To carry residents and guests nearer to the native atmosphere, the plan is to finish three three-story lookout factors – two of which have already been constructed – and piers reaching into the lagoon, a part of which can be utilized for fishing, as fish nonetheless inhabit the lagoon regardless of the air pollution of latest many years.
The primary part, referred to as Haciendita Cafubá, was inaugurated on Jun. 17, with a water filtration system for the Cafubá River, one of many three that circulate into the lagoon, a lookout level, piers, a bicycle path and even a nursery for new child crocodiles in a particular fenced-in space.

“I went to see if I may discover the crocodiles, my son made me stroll down the road, he loves animals… I by no means thought I’d see what I noticed… I went to the start of the Haciendita, I noticed fish the place there was nothing residing earlier than, I noticed flowers the place there was solely mud, I noticed life the place nature was already useless with none hope. Congratulations for tolerating us, that neighborhood is hard.”
That is the testimony of a resident, addressed to the pinnacle of PRO Sostenible. The park has had numerous guests since earlier than its inauguration, attracted by natural world that had lengthy since disappeared from the shores of the lagoon.
The expertise used to scrub the waters is thought world wide however has not been extensively utilized in Brazil. It’s based mostly on filter gardens, wherein layers of gravel and permeable substrates function a base for macrophytes, aquatic vegetation that reside in flooded areas and are seen on the floor.
The vegetation filter the water in a course of that doesn’t require chemical inputs.
A particular spillway receives the waters of the Cafubá, which conducts and controls them to present larger effectivity to the subsequent pond, the sedimentation pond, step one in cleansing the polluted waters by decreasing the strong materials produced by erosion and rubbish thrown into the riverbed.
After the sedimentation basins, the water passes by means of three filtering gardens earlier than flowing into the lagoon.

Plantfilters
Twelve species of macrophytes are used within the filtration course of, however the selection has been decreased resulting from upkeep difficulties. “We use solely Brazilian species, and no exogenous species,” stated Heloisa Osanai, a biologist specialised in environmental administration and one of many 17 staff of PRO Sostenible.
Examples embody water lettuce and water lilies with orange flowers.
“One of many results of the water therapy is the discount of mosquitoes, which is essential to native residents, who used to burn dry vegetation in an try to drive away the bugs. Individuals not construct bonfires within the evenings. The filter gardens entice dragonflies that eat the mosquitoes,” stated Osanai.
Within the bigger Jacaré River, 11 filtering gardens had been created, which function in sequence and whose dimension was designed for larger effectivity, stated Andrea Maia, one other biologist and environmental supervisor of the workforce.

Awards and outcomes
PRO Sostenible has already received a number of nationwide and worldwide awards. It was named one of many three finest environmental sustainability packages in Latin America and the Caribbean within the Sensible Cities 2022 award.
This 12 months it received one other award from Sensible Cities Latin America, as the most effective in Sustainable City Improvement and Mobility. The Park additionally received awards for valuing biodiversity, from the Federation of Industries of Rio de Janeiro, and one other as an environmental venture, from the São Paulo metropolis authorities, for contributing to the Sustainable Improvement Targets of the 2030 Agenda.
Along with the Park, this system has inaugurated a Sports activities and Leisure Heart on the island of Tibau, on the opposite facet of the Piratininga Lagoon, nearer to the ocean.
As a part of this venture, sports activities fields, a playground and a lookout level have been constructed, whereas an invasive tree, the white lead tree (Leucaena leucocephala), native to Mexico and Central America, which dominated the island’s vegetation, has been progressively changed with native species.
The systemic pondering that guides PRO Sostenible relies on three pillars, defined Dionê Castro.
First is the complexity of native ecosystems and of the initiatives being applied, specializing in the environmental, pure, social and cultural dimensions.
In second place is what is named “intersubjectivity”, which takes into consideration new paradigms of science, abandoning “simplistic and Cartesian views…The modifications don’t come from outdoors, however from native residents, with public enter from the conception of the venture to its execution,” stated the geographer who holds a doctorate in environmental administration.
The third pillar is irreversibility. The lagoon and its ecosystems is not going to return to their authentic state, “to zero,” however can be cleaned up as a lot as potential to achieve a “new equilibrium,” she stated.
Native help for the environmental venture led to options in several areas, such because the regularization of actual property within the favelas or shantytowns, the development of well being, the revitalization of fishing, and even the creation of a fishermen’s affiliation.
“It is environmental justice on the march,” Castro summed up.
