NITERÓI, Brazil, Jan 9 2026 (IPS)
“We moved from a context of socio-environmental exclusion to one of environmental justice,” said Dionê Castro, coordinator of the Sustainable Oceanic Region Program which led Brazil’s largest nature-based solutions project.
Having won national and global awards, the Orla Piratininga Park (POP) built 35,000 square meters of filtering gardens and improved the water quality of the Piratininga lagoon, in the oceanic south of Niterói, a municipality in metropolitan Rio de Janeiro, across the Guanabara Bay.
The project, named after the late Brazilian environmentalist Alfredo Sirkis, began in 2020, and aims to environmentally restore an area of 680,000 square meters on the lagoon’s shores whose waters cover an area of 2.87 square kilometers.
At the heart of the project are the treatment systems for the waters of the Cafubá, Arrozal, and Jacaré rivers, which flow into the lagoon. Sedimentation and pollution were deteriorating the water resource and the quality of life in the surrounding area.
A weir, which receives the river flow, a sedimentation pond, which removes solid waste, and the filtering gardens make up the chain that partially cleans the water before releasing it into the lagoon, reducing environmental impacts, in a process called phytoremediation.
The gardens are small reservoirs where aquatic plants called macrophytes are planted, which feed on the nutrients from the pollution, explained Heloisa Osanai, the biologist specialized in environmental management of the Sustainable Oceanic Region Program (PRO Sustainable).
Three polluted water treatment stations are in the neighborhoods crossed by the rivers, based on natural resources, “without the use of electrical energy, chemicals, or concrete,” explained Castro, the coordinator of PRO Sustainable.
Furthermore, some macrophytes produce abundant flowers. Only native Brazilian species are planted, with priority given to biodiversity, added Osanai.
Along with these water treatment systems, 10.8 kilometers of bike paths, 17 recreation centers, a 2,800-square-meter Eco-Cultural Center, and other environmental works with social goals were built.
The bike path, generally along a pedestrian sidewalk, caters to physical and leisure activities but is also a factor in protecting the lagoon shoreline by blocking urban occupation and real estate invasions, explain the officials.
The area where the water system was built at the mouth of the Cafubá river was highly degraded by an open-air dump and flooding. A reformed “belt channel,” in some sections also reinforced by macrophyte islands, corrected the waterlogging.
On the other side of the lagoon, 3.2 kilometers of bioswales improve the drainage of rainwater. They are trenches with pipes, stones, and other materials, plus vegetation, that accelerate drainage and prevent pollutants from reaching the lagoon.
The main result, according to Castro, reconciled the local population with the lagoon. The old houses that “turned their backs on the lagoon” are joined by new buildings facing the water, some with balconies overlooking the new landscape, said Mariah Bessa, the engineer in charge of hydraulic aspects of the project.
The local population was highly involved in the design and construction of the new environmental and social facilities that transformed the lagoon shoreline. This led to new attitudes, such as not littering on the ground or in the water and preventing others from doing so, according to Castro.
The Ecocultural Center promotes permanent environmental education, with films, children’s games, audiovisual resources, and a large space for visits and classes.
“We moved from a context of socio-environmental exclusion to one of environmental justice,” said the coordinator of PRO Sustainable.

WASHINGTON, USA, Jan 9 2026 (IPS)
The Trump Administration’s sweeping executive order to withdraw the United States from dozens of United Nations bodies and international organizations, as well as a treaty ratified by the United States with the advice and consent of the US Senate, is a targeted assault on multilateralism, international law, and global institutions critical to safeguarding human rights, peace, and climate justice.
This move, the constitutionality and legal effect of which are questionable, was announced under the guise of protecting US interests, but does exactly the opposite. By divesting from global cooperation on the environment, human rights, democracy, and peace, the US puts its own future, and that of the planet, at greater risk.
The Executive Order represents a deliberate effort to dismantle the international infrastructure designed to uphold dignity, protect children, improve gender and racial equality, advance sustainable development, preserve the oceans, and confront the climate crisis. It undermines bodies that safeguard the global commons and ensure basic protections for marginalized people and those in vulnerable situations around the world, including refugees, women, children, people of African descent, and many others.
Rebecca Brown, President and CEO of the Center for International Environmental Law (CIEL) said:
“This executive order is not just a policy shift— it is a direct assault on the multilateral system that has helped prevent conflict, advance human rights, and protect the global commons for nearly eighty years. At a time when rising seas, record heat, and deadly disasters demand urgent, coordinated action, the US government is choosing to retreat.”
“The decision to defund and withdraw from the UN Framework Convention on Climate Change (UNFCCC) does not absolve the US of its legal obligations to prevent climate change and remedy climate harm, as the world’s highest court made clear last year. This action is simply a continuation of this Administration’s efforts to prioritize corporate interests over people and planet, and flout the rule of law.
Withdrawing from institutions designed to support global climate action does not change the stark reality of the climate crisis, rebut the irrefutable evidence of its causes, or eliminate the US’s clear responsibility for its consequences. Withdrawal only serves to further isolate the US to the detriment of its own population and billions around the world.”

UNITED NATIONS, Jan 8 2026 (IPS)
President Donald Trump’s executive order to stop United States support for 66 international organizations, including 31 United Nations (UN) groups, has faced strong opposition from these organizations, the global community, humanitarian experts, and climate advocates, who are concerned about the negative effects on global cooperation, sustainable development, and international peace and security.
This executive order follows earlier withdrawals from the World Health Organization (WHO), the United Nations Relief and Works Agency for Palestinian Refugees in the Near East (UNRWA), the United Nations Human Rights Council (UNHRC), and the United Nations Educational, Scientific, and Cultural Organization (UNESCO). The United States has recently reduced its funding for foreign aid organizations.
The majority of the affected bodies in this executive order are organizations that center around issues in climate change, labor, peacekeeping, migration, and civic space conditions. In a statement from the U.S. Department of State, it is confirmed that Trump’s review of these organizations found them to be “wasteful, ineffective, and harmful.”
The executive order primarily affects organizations that address climate change, labor rights, peacekeeping, migration, and civic space conditions. In a statement, the department described the organizations, calling them vehicles for “progressive ideologies” funded by American taxpayers and misaligned with United States’ national interests.
“The Trump Administration has found these institutions to be redundant in their scope, mismanaged, unnecessary, wasteful, poorly run, captured by the interests of actors advancing their agendas contrary to our own, or a threat to our nation’s sovereignty, freedoms, and general prosperity,” said United States Secretary of State Marco Rubio. “President Trump is clear: It is no longer acceptable to be sending these institutions the blood, sweat, and treasure of the American people, with little to nothing to show for it. The days of billions of dollars in taxpayer money flowing to foreign interests at the expense of our people are over.”
The order instructs all executive departments and agencies to begin implementing the withdrawals immediately. For the affected UN agencies, this entails ending United States participation and halting funding. Rubio also confirmed that the review of additional international organizations is still underway.
Humanitarian experts and spokespersons for many of the affected entities have voiced alarm and condemnation with President Trump’s order, warning of severe consequences for climate action, human rights, peacebuilding efforts, multilateral governance, and global crisis-response systems—particularly at a time of mounting international instability.
“Today, we are witnessing a complete shift from global cooperation towards transactional relations,” said Yamide Dagnet, Senior International Vice President at the Natural Resources Defense Council (NRDC).
“It is becoming less about shared principles, rule of law, and solidarity, thereby risking more global instability. By choosing to run away from addressing some of the biggest environmental, economic, health, and security threats on the planet, the United States of America stands to lose a lot. With diminishing credibility and competitiveness in the industries of the future, the United States will be missing out on job creation and innovation, ceding scientific and technological leadership to other countries,” Dagnet said.
She called on world leaders to commit to multilateralism.
“The world is bigger than the United States—and so are the solutions to our problems, which require global cooperation more than ever, including among states, provinces, and cities globally. This is the moment when world leaders need to resolutely commit to multilateral collaboration if we’re going to overcome these global threats to ensure a safe and sustainable future for all.”
Many have also criticized the United States’ à la carte approach to meeting its international obligations, only supporting the operations and agencies that align with President Trump’s priorities.
“I think what we’re seeing is the crystallization of the United States approach to multilateralism, which is ‘my way or the highway,’” said Daniel Forti, the head of UN affairs at the International Crisis Group. “It’s a very clear vision of wanting international cooperation on Washington’s own terms.”
The Intergovernmental Science Policy Platform on Biodiversity and Ecosystem Services (IPBES) said it regretted “the deeply disappointing news of the United States’ intention to withdraw its participation in IPBES, along with more than 60 other international organizations and bodies.”
Dr. David Obura, Chair of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES), said the U.S. was a founding member and “scientists, policymakers and stakeholders—including Indigenous Peoples and local communities—from the United States have been among the most engaged contributors to the work of IPBES since its establishment in 2012, making valuable contributions to objective science-based assessments of the state of the planet for people and nature.”
Apart from their contributions to IPBES, “decision-makers in the United States—at all levels and in all spheres of society—have also been among the most prolific users of the work produced by IPBES to help better inform policy, regulations, investments and future research.”
Obura thanked the United States for their contribution but noted that the withdrawal would have a massive impact on IPBES and the planet.
“Unfortunately, we cannot withdraw from the fact that more than 1 million species of plants and animals face extinction. Nor can we change the fact that the global economy is losing as much as USD 25 trillion per year in environmental impacts, or restore the missed opportunities of not acting now to generate more than USD 10 trillion in business opportunity value and 395 million jobs by 2030.”
Historically, the United States has been the largest financial contributor to the UN, providing approximately 22 percent of the organization’s regular budget and roughly 28 percent of all peacekeeping funds.
The withdrawal of United States support from 31 UN bodies is expected to trigger substantial budget shortfalls, cutbacks in humanitarian staffing, and the loss of critical technical expertise supplied by its personnel. These setbacks are likely to hinder progress toward the Sustainable Development Goals (SDGs), reduce food assistance and medical services for people in protracted crises, and embolden authoritarian governments to resist humanitarian oversight and intervention.
“The US decision to disengage from dozens of United Nations programs and agencies, along with other international bodies, is just President Trump’s latest assault on human rights protections and the global rule of law,” said Louis Charbonneau, UN director at Human Rights Watch (HRW).
“Whether withdrawing from the Human Rights Council or defunding the UN Population Fund, which helps millions of women and girls around the world, this administration has been trying to destroy the very same human rights institutions that the US helped build over the last 80 years. UN member countries should resist the US campaign to demolish tools they use to uphold human rights and ensure that vital UN programs have the funding and political support they need.”
At a press briefing at the UN Headquarters, Stéphane Dujarric, spokesperson for the UN Secretary-General António Guterres, informed reporters of the UN’s reaction to the United States withdrawal, emphasizing that the UN remains committed to assisting people in need regardless of United States participation
“As we have consistently underscored, assessed contributions to the United Nations regular budget and peacekeeping budget, as approved by the General Assembly, are a legal obligation under the UN Charter for all Member States, including the United States,” said Dujarric.
“All United Nations entities will go on with the implementation of their mandates as given by Member States. The United Nations has a responsibility to deliver for those who depend on us. We will continue to carry out our mandates with determination.”
