In a public notice issued on Tuesday, August 11, the City said the building had been reopened following the initial implementation of measures required to address sanitation concerns and improve the safety of people working there.
However, the reopening does not mean all corrective measures have been completed. The management of Inkundamahoro Building has been instructed to continue addressing outstanding requirements, including installing an appropriate wastewater treatment system, ensuring the daily collection and proper disposal of solid waste, carrying out necessary repairs and repainting, among other measures.
The reopening comes just days after the City temporarily closed the building over continued failure to comply with safety, sanitation and environmental requirements.
In a notice issued on August 8, the City said it had issued several directives and notices between May and August requiring the management to address deficiencies. Despite the interventions, key concerns remained unresolved, including the discharge of untreated wastewater from toilets directly into a wetland.
The City said the latest incident involving the discharge of untreated wastewater was confirmed on August 7, prompting the temporary closure. The City had warned that the building would remain closed until the required corrective measures were implemented and compliance verified by the relevant authorities.
Following the initial implementation of those measures, the City has now permitted the building to reopen while requiring management to complete the outstanding work.
The City also reminded people working in Inkundamahoro Building of their responsibility to maintain cleanliness and proper sanitation in their workplace.
At the same time, the warning extends beyond Inkundamahoro. The City reminded all building managers, particularly those managing buildings that accommodate large numbers of people, to comply with applicable sanitation, safety and environmental requirements.
“Those who fail to comply with these requirements or to implement corrective measures recommended following inspections will be held accountable,” the City said in its latest notice.

Researchers from the Helmholtz-Zentrum Dresden-Rossendorf, working with Wismut GmbH and the University of Granada, found that bacteria living in uranium contaminated mine water can help remove the metal from water when supplied with glycerol, a substance that serves as a food source for microorganisms.
In laboratory experiments, about 95 percent of the dissolved uranium disappeared from the water within 130 days.
Uranium is a radioactive heavy metal that is normally locked inside minerals in soil. However, mining and other environmental processes can cause it to dissolve and enter groundwater.
Once uranium becomes mobile in water, it can spread through the environment and pose risks because of its toxicity.
The researchers wanted to understand not only whether bacteria could reduce the amount of uranium dissolved in water, but also what happened to the uranium after it was removed.
The team collected water from a flooded uranium mine in Germany’s Ore Mountains.
The mine, operated by Wismut GmbH, provided researchers with a naturally occurring community of microorganisms.
In the laboratory, the scientists added controlled amounts of glycerol to samples of the mine water and created oxygen free conditions similar to those found deep underground.
As the bacteria used the glycerol as a food source, the concentration of dissolved uranium gradually fell.
After 130 days, only about five percent of the uranium originally dissolved in the water remained. Further investigation showed that the uranium had accumulated within the bacteria’s cell walls.
The researchers then used advanced microscopy and spectroscopy techniques to determine what form the uranium had taken.
Their analysis revealed an unexpected result. A significant amount of the uranium had entered a chemical state known as pentavalent uranium, or uranium with a valency of five.
Pentavalent uranium has generally been considered rare and unstable, with scientists previously viewing it as a temporary chemical state.
The team discovered that the uranium had combined with iron and oxygen to form a compound known as FeU(V)O4.
The compound is particularly interesting because previous research had shown that it could remain stable even when exposed to atmospheric oxygen for more than 25 years.
However, scientists had not previously understood how the compound could naturally form or that bacteria could play a role in its formation.
The new experiments provided another surprise.
When the researchers exposed dried bacterial material containing the uranium compound to oxygen, the amount of FeU(V)O4 actually increased rather than decreased.
This suggests that the compound may be more stable in oxygen rich conditions than previously expected. It also strengthens the possibility that bacterial activity could help transform mobile uranium into a form that is less likely to spread through water.
Dr Evelyn Krawczyk-Bärsch, a scientist in HZDR’s Terrestrial Microbiology research group and a co author of the study, said the findings showed for the first time that bacteria supplied with glycerol can convert dissolved uranium into a stable chemical compound.
However, the researchers stressed that more work is needed before the discovery can be turned into a practical method for cleaning contaminated environments.
The scientists now plan to investigate the uranium binding bacteria in greater detail and study the biochemical and geochemical processes responsible for the transformation.
A better understanding of these processes could help determine whether microorganisms can eventually be used as part of efforts to remediate uranium contaminated water and other environments.
Scientists have uncovered an unexpected role for bacteria in converting mobile uranium into a stable chemical form.
The country is building a carbon market system that allows verified climate projects to generate carbon credits, which can then be sold to organisations seeking to reduce their greenhouse gas emissions.
Each carbon credit represents one tonne of carbon dioxide equivalent that has been reduced, avoided or removed from the atmosphere through an approved activity.
For Rwanda, carbon markets are part of a broader strategy to support its ambition of becoming a climate-resilient and carbon-neutral economy by 2050.
The country is exploring these markets as a way to attract climate finance, support green growth and fund projects in areas such as clean energy, forestry, sustainable agriculture, waste management and clean cooking technologies.
Although Rwanda contributes a relatively small share of global greenhouse gas emissions, it faces significant climate-related challenges, including risks linked to floods, droughts, land degradation and changing weather patterns.
The government considers climate finance an important requirement for implementing mitigation and adaptation measures under its climate commitments.
Carbon markets operate through different mechanisms. They include the Clean Development Mechanism (CDM) established under the Kyoto Protocol, voluntary carbon markets and mechanisms created under Article 6 of the Paris Agreement.
Article 6 allows countries to cooperate in achieving climate targets through approaches that include transferring emission reductions between countries. However, such transactions require strong systems to verify reductions and prevent the same emission reduction from being counted more than once.
Carbon markets allow high-emitting companies and countries to offset part of their emissions by buying verified carbon credits from projects that reduce or remove greenhouse gases.
Carbon market framework and international partnerships
Rwanda established a major foundation for its carbon market ambitions in December 2023 when it launched its National Carbon Market Framework on the sidelines of the United Nations Climate Change Conference (COP28) in Dubai.
Developed through the Rwanda Environment Management Authority (REMA), the framework establishes rules for generating, approving, monitoring and trading carbon credits. It aims to enhance transparency, safeguard environmental integrity and strengthen Rwanda’s participation in global carbon markets.
The framework also lays the foundation for Rwanda’s engagement in Article 6 mechanisms under the Paris Agreement by setting procedures for project authorisation, emission reduction verification and carbon accounting.
At its launch, Rwanda said the initiative would support the transition to a low-carbon economy by attracting investment in clean technologies and sustainable solutions while ensuring locally generated carbon credits meet international standards.
However, establishing the framework was only the first step. Rwanda has since focused on strengthening the systems, skills and project pipeline needed to make the carbon market operational.
On March 27, 2025, the Global Green Growth Institute (GGGI) and the Government of Rwanda, through REMA, launched a project aimed at improving Rwanda’s readiness to participate meaningfully and equitably in international carbon markets under Article 6 of the Paris Agreement.
The two-year project, supported through GGGI’s Carbon Transaction Facility with a budget of $854,859, focuses on operationalising Rwanda’s National Carbon Market Framework.
The initiative addresses challenges including limited awareness among public and private sector actors about Article 6 opportunities, capacity gaps among stakeholders and the need to develop a stronger pipeline of high-quality mitigation projects.
Under the project, GGGI and REMA are supporting capacity building, strengthening governance systems, developing guidelines and supporting the identification of carbon projects in key sectors, including agriculture, forestry, energy, transport and waste management.
The initiative is also intended to improve engagement between project developers, government institutions and potential international buyers.
Rwanda has also entered into several international partnerships to support its carbon market participation.
In December 2023, Rwanda signed cooperation agreements with Singapore and Kuwait to advance collaboration under Article 6 of the Paris Agreement.
In September 2024, the Rwanda Green Fund (FONERWA), REMA, Gold Standard and Singapore-based investment company GenZero signed an agreement to develop a pipeline of Article 6-compliant carbon credit projects.
The partnership focuses on identifying projects capable of generating high-integrity carbon credits while providing additional benefits such as biodiversity protection, improved livelihoods and job creation.
In January 2026, Rwanda and Singapore launched a call for proposals for high-quality carbon credit projects under their bilateral implementation agreement, inviting developers to submit both technology-based and nature-based initiatives.
Improved cookstove projects are at the centre of Rwanda’s carbon market journey, helping households reduce reliance on firewood, cut emissions and improve indoor air quality while generating carbon credits for climate finance.
Projects, communities and the future of Rwanda’s carbon market
Rwanda’s carbon market activities have so far been largely driven by improved cookstove projects, which remain among the most developed climate initiatives in the country. These projects help households transition from traditional cooking methods that rely heavily on firewood to more efficient technologies.
Besides reducing greenhouse gas emissions, they contribute to lower indoor air pollution and reduced pressure on forests.
Improved cookstove projects accounted for about 87 percent of Certified Emission Reductions issued from Rwanda’s carbon market activities, according to national climate data. Lighting and solar projects accounted for much of the remaining share.
By December 2020, Rwanda had received more than 2.25 million carbon credits through Clean Development Mechanism and Voluntary Carbon Market activities.
The country is now expanding beyond clean cooking into other areas, including forestry restoration, agroforestry, renewable energy, sustainable agriculture and water purification.
In June 2025, REMA announced that 19 projects were ready to participate in international carbon markets. The projects included 12 energy-efficient cookstove initiatives, three agroforestry and reforestation projects and four water purification projects.
Rwanda is also putting emphasis on ensuring that carbon finance benefits communities involved in climate projects.
New regulations require that at least 30 percent of revenues generated from land-based carbon projects directly benefit communities, landowners, farmers and other stakeholders whose land contributes to the projects.
The government expects carbon markets to become an additional source of climate finance. Rwanda estimates that selling 7.5 million tonnes of carbon dioxide equivalent in carbon credits could generate about $337 million, depending on market prices.
To support investors, GGGI and REMA have also developed practical guidance explaining carbon market opportunities, project requirements and approval processes.
Potential areas for investment include forestry projects, renewable energy installations, methane capture, energy efficiency initiatives, clean cooking solutions and sustainable agricultural practices.
Rwanda’s efforts come as African countries seek to increase their participation in global carbon markets. Kigali is scheduled to host the Carbon Markets Africa Summit in October 2026, bringing together governments, investors, project developers and climate finance institutions to discuss opportunities for scaling credible carbon markets on the continent.
As international buyers increasingly seek high-integrity credits, Rwanda is moving from establishing regulatory frameworks to developing projects that can attract investment and deliver tangible climate outcomes.
Through initiatives such as Green Gicumbi, Rwanda is restoring degraded forests and helping ecosystems recover their natural state. These reforestation efforts contribute to carbon removal, biodiversity conservation and sustainable livelihoods while creating opportunities within the country’s emerging carbon market.
A study from Griffith University found that bones recovered from underwater caves in South Australia carry unique “fingerprints” shaped by the conditions they experienced after the animals died.
These changes were influenced by darkness, algae, bacteria, and other environmental factors inside the caves.
The findings provide researchers with a new method to investigate how the remains of ancient megafauna, including some of the giant animals that once roamed Australia, entered and survived in underwater cave systems.
Scientists have long studied fossilized bones to understand extinct species, but determining how those remains arrived in unusual locations such as submerged caves has remained a challenge.
The new research suggests that microscopic changes preserved on bones can reveal important information about their journey through different environments.
According to the researchers, underwater caves create unique conditions that can preserve biological remains for thousands of years. The absence of sunlight, along with interactions between minerals, microorganisms, and water, leaves distinctive marks on bones that act like environmental records.
These clues allow scientists to examine not only the animals themselves but also the conditions surrounding their burial and preservation.
The research could improve scientists’ understanding of ancient ecosystems and provide new insights into Australia’s extinct megafauna, a group of large animals that disappeared thousands of years ago.
By studying these hidden signals inside underwater cave bones, researchers hope to reconstruct the events that brought extinct giants to their final resting places and learn more about how environmental changes affected ancient life.

The UN chief made the appeal at a press encounter, citing an update on El Nino forecasts released by the World Meteorological Organization (WMO).
According to the new forecasts, this summer’s extremes — record-shattering heat domes, apocalyptic wildfires, thousands of lives lost in scorching conditions, record-high global sea-surface temperatures — are only a warm-up act, said Guterres.
El Nino is strengthening, adding fuel to a planet already on fire. The Pacific waters driving the phenomenon have never been this warm this early in an El Nino and temperatures are still rising, he said. “At the same time, WMO’s outlook shows that through October, nearly every land area on Earth is expected to be hotter than normal.”
El Nino does not bring heat alone; it profoundly affects the world’s rainfall. India’s monsoon is already running well below average. Hotter and drier conditions are forecast from Central America and the Caribbean to parts of South America, South Asia, the Southwest Pacific, Europe and Africa, warned Guterres.
“The verdict is clear: the climate crisis is in overdrive,” he said.
The UN chief called for action on four fronts: protect people before heat becomes deadlier, make work safer, build and retrofit for the coming heat, and stop fueling the climate crisis.
Extreme heat is a society-wide threat that demands a government-wide response. Every city and country should have heat-health action plans, early warning systems and public health measures that reach every community in time. And access to sustainable cooling must expand urgently and equitably, he said.
Governments and employers must set heat standards, adjust working hours, and protect incomes when work must stop. Protection from extreme heat must be designed into cities, homes, schools and hospitals, and factored into every plan and public budget, he said.
Guterres warned that every new fossil fuel project approved today makes tomorrow’s heatwaves more dangerous, and the world less secure.
“Today’s findings show that extreme heat is not a future threat. It is here. It is becoming more dangerous. And unless we act — to protect people and tackle the root cause of the crisis — it will become deadlier still,” he said. “The warm-up act is over. We cannot afford to wait for the main event.”

The elephants were found dead in the Amboseli ecosystem, which includes Amboseli National Park, a renowned wildlife sanctuary that is home to thousands of elephants and attracts visitors from around the world.
According to the Kenya Wildlife Service (KWS), laboratory tests conducted on samples collected from the dead elephants detected cyanide, a highly toxic chemical. Authorities believe the animals consumed tomatoes that had been contaminated with the poison after venturing onto farmland bordering the protected area.
The discovery followed weeks of investigations into the deaths, which occurred between late June and late July. Wildlife officials had initially suspected poisoning after several elephants showed unusual symptoms, including partial paralysis, before dying.
KWS Director General Erustus Kanga said the poisoning is a serious concern because it could affect more than just wildlife.
“Other than the elephants and the wildlife that may be feeding in those fields, we have the local livestock. We have the goats. We have the cattle that are there. Eventually, if this is truly what is in the system, then we are going to see a bigger impact,” Kanga said.
Authorities have not yet determined who contaminated the tomatoes or whether the poisoning was deliberate. Investigators are examining the circumstances surrounding the incident as they work to establish whether criminal activity was involved.
Kenya has previously experienced cases in which elephants were intentionally poisoned after straying onto farms and destroying crops. As agriculture continues to expand near wildlife habitats, conflicts between local communities and elephants have become more frequent.
Although cyanide is highly poisonous, KWS said there is currently no evidence that the contamination poses an immediate risk to people. However, officials are continuing environmental assessments and monitoring the area to determine whether other animals may have been affected.
The deaths have sparked concern among conservationists, who warn that the incident highlights the growing pressure facing Kenya’s wildlife as human activities increasingly overlap with protected ecosystems.
The Kenya Wildlife Service said investigations remain ongoing and pledged to continue working with local communities to strengthen wildlife protection while reducing conflicts between people and elephants.

The investment was disclosed by the Nyungwe Management Company (NMC), which manages the park under African Parks, during a stakeholders’ meeting held on July 9, 2026.
The meeting brought together representatives from the judiciary, law enforcement agencies, security institutions and local government officials from Nyaruguru District to review progress in the park’s conservation and management.
According to NMC, more than $20 million (over Rwf30 billion) has been invested since African Parks assumed management of Nyungwe in 2020 under a 20-year agreement with the Government of Rwanda.
A long journey of conservation
Nyungwe’s conservation history dates back to 1933, when Belgium designated the forest as a protected reserve during the colonial period.
Despite its protected status, illegal mining for gold and widespread poaching continued for decades, leading to the disappearance of species such as elephants and buffaloes from the forest.
Management of the forest was later transferred to the former Office of Tourism and National Parks (ORTPN) in 1987.
During the 1994 Genocide against the Tutsi and its aftermath, the forest suffered significant degradation as refugees crossed through it into the Democratic Republic of Congo. Between 1997 and 2000, severe wildfires destroyed approximately 12 percent of the forest.
Recognizing its ecological importance, the Government of Rwanda upgraded Nyungwe to national park status in 2005, strengthening its protection. In 2020, management was entrusted to African Parks, an international conservation organization specializing in protected area management.
UNESCO recognition and major investments
The park’s manager Protais Niyigaba said it has recorded significant achievements over the past five years, including being inscribed on the UNESCO World Heritage List in 2023.
He said the listing served as international recognition of Nyungwe’s outstanding ecological value and Rwanda’s efforts to preserve the forest.
“The UNESCO inscription was like passing an international examination that confirmed the exceptional value of this forest and demonstrated the country’s strong commitment to protecting it,” he said.
Niyigaba noted that the more than $20 million invested has supported conservation, tourism infrastructure, staffing and community development.
The number of permanent employees has increased from 153 to 354, while more than 300 additional workers are regularly employed in conservation and park maintenance activities.
Stronger partnerships with surrounding communities
NMC said relations between the park and neighboring communities have continued to improve, with positive community engagement rising from 75 percent in 2022 to 83 percent today.
More than 100 former poachers now work alongside conservation teams to help protect the park.
In addition, 34 community cooperatives have received grants totaling more than $539,000 (nearly Rwf800 million) to support income-generating activities. According to NMC, many of these cooperatives have nearly tripled their revenues.
Supported projects include mushroom farming, cultural handicrafts, fish farming, small livestock rearing and community-based tourism, while local residents are also employed in park maintenance and restoration activities.
Niyigaba said a major ecosystem restoration project valued at Rwf10 billion is expected to create employment for more than 1,500 people as damaged sections of the park are rehabilitated.
Moving toward financial self-sufficiency
The park is also making steady progress toward financial sustainability.
According to NMC, Nyungwe generated only 4 percent of its operating budget internally when African Parks took over. By 2025, that figure had risen to 48 percent, with the goal of becoming fully self-financing within the next decade.
To support this objective, significant investments have been made in tourism infrastructure.
These include construction of the park’s first permanent headquarters at Gisakura, replacing rented offices, as well as recreational facilities including a gymnasium.
The park has also opened its zipline attraction and the Munazi Lodge, located in the heart of Nyungwe, to enhance visitor experiences while generating additional revenue.
“We continue investing in revenue-generating activities so that the park can eventually operate without relying on donor support. That is the overall objective behind these investments,” Niyigaba said.
Tourism continues to grow
Tourism performance has improved significantly despite disruptions caused by regional disease outbreaks such as Marburg and Ebola, which temporarily affected international travel.
According to NMC, tourism revenue increased eightfold between 2021 and 2025, while annual visitor numbers rose from more than 17,000 to around 29,000, including a growing number of Rwandan tourists.
Among the 24 protected areas managed by African Parks across 13 African countries, Rwanda’s parks attract the highest visitor numbers, with Akagera National Park ranking first and Nyungwe National Park second.
One of Africa’s richest rainforests
Covering 1,019 square kilometres, Nyungwe National Park is one of Africa’s oldest and most biodiverse montane rainforests.
The park is home to 13 species of primates, more than 300 bird species, and over 1,000 plant species, making it one of Rwanda’s premier ecotourism destinations.
Beyond its biodiversity, Nyungwe plays a vital environmental role as Rwanda’s largest water catchment, supplying nearly 70 percent of the country’s freshwater resources. It is also regarded as one of the sources of the River Nile, further underscoring its regional ecological significance.
Nyungwe National Park has received more than Rwf30 billion in investment over the past five years, strengthening conservation, tourism infrastructure and community development.The park is home to 13 species of primates.

Sixty-three agricultural fires have been fully extinguished, one was brought under control and placed under monitoring, while another remained active in the eastern province of Setif, the department said in a statement.
All other fires across several northern and southern provinces have been completely extinguished, it said.
The department attributed the outbreak to high temperatures and dry conditions increasing the risk of wildfires and accelerating their spread.
A persistent heatwave sweeping across large parts of Algeria has fueled dozens of vegetation fires, with firefighting crews responding to 127 blazes over the past 24 hours, the country’s Civil Protection Department said Saturday.
A widely used pesticide designed to protect crops from harmful insects may also be affecting the reproductive health of bumblebees, raising concerns about the long-term survival of one of the world’s most important pollinators.
Researchers from the Georgia Institute of Technology found that low levels of exposure to sulfoxaflor, a modern pesticide used against crop pests such as aphids, can alter gene activity in bumblebees, especially in tissues linked to reproduction.
Bumblebees play a crucial role in global agriculture by helping pollinate many crops.
Scientists estimate that pollinators contribute to about one third of the world’s food production, making their protection essential for food security.
Although sulfoxaflor was developed to target harmful insects and improve crop production, researchers say its effects on beneficial insects such as bees need greater attention.
The chemical is already known to be toxic to bees, but the new study reveals how even small amounts may affect their biology at the molecular level.
The research team exposed worker bumblebees to low doses of the pesticide and later examined changes in their gene expression.
The greatest changes were found in ovarian tissues, suggesting that the chemical may interfere with reproductive processes and reduce the number of offspring produced by bee colonies.
To understand the impact, scientists analyzed bee tissues and studied RNA activity, which helps reveal how genes respond to environmental stress.
They also used computer models to identify the biological systems most affected by pesticide exposure.
Researchers say the findings provide an important connection between molecular changes inside bees and possible consequences for entire colonies.
Reduced reproduction among bumblebees could eventually contribute to population declines and threaten pollination systems that agriculture depends on.
The study highlights a major challenge facing modern farming: finding ways to control crop-damaging pests while protecting beneficial insects.
Scientists say better pest management strategies are needed to maintain healthy bee populations while ensuring reliable food production.
Beyond pesticides, bumblebees are also facing other environmental pressures, including rising temperatures and more frequent heatwaves, which add further stress to already vulnerable populations.
Researchers hope that a better understanding of how chemicals affect pollinators will help farmers and policymakers develop safer agricultural practices that protect both crops and the insects that support ecosystems worldwide.
