CAPE TOWN, South Africa, Jul 4 2025 (IPS)
Concerns about the impacts of invasive species is not new; it dates to the 19th century. The term was popularized in Charles Elton’s 1958 book “The Ecology of Invasions by Animals and Plants”. However, the concept gained significant attention in the 1990s and early 2000s as academic interest surged. This led to an increase in publications by invasion biologists.
Today, the impact of invasive species has increased significantly, with regions with fragile ecosystems being more vulnerable than others. Globally, the scale of the problem is staggering. The International Union for Conservation of Nature (IUCN) estimates that the minimum economic cost of biological invasions globally from 1970 to 2017 is USD 1.2 trillion. This figure accounts for expenses related to the prevention, reduction, or mitigation of damages caused by these species.
In Africa, a continent expected to be severely affected by climate change, the challenges posed by invasive species are expected to worsen. Among the most pressing is the spread of invasive plants, which not only endanger native biodiversity but also impact the economy, water security, food security and livelihoods.
One such example can be found in South Africa’s Cape Floristic Region, which is known for its remarkable plant diversity, where 70% of plant species are unique to this area.
In catchment areas of the Western Cape Water Supply System, critical for the water supply to Cape Town, invasive trees are responsible for the loss of up to 55 million cubic meters of water per year—equivalent to about two months’ water supply for the city. If not managed, this loss could increase to 100 million cubic meters per year by 2045.
It is evident that the Earth is approaching a tipping point in terms of biodiversity loss, and there is no time to waste. Many scientists, including myself, are deeply concerned about the impact of these water-consuming invasive trees.

As the Science, Monitoring, Evaluation, and Learning Manager for The Nature Conservancy (TNC) in South Africa, I lead a team dedicated to using sound science to monitor and evaluate the progress of the Greater Cape Town Water Fund, which was launched in 2018 by TNC and its partners as South Africa’s first Water Fund.
Our work includes tracking the hectares cleared in pursuit of our 2026 target of 59,300 hectares cleared, along with assessing the associated water benefits and biodiversity impacts (for both freshwater ecosystems and the recovery of native fynbos).
As of February 2025, the Water Fund has cleared 33,000 hectares (56% of the target) and completed follow-up clearing efforts across 31,000 hectares to prevent regrowth of invasive species and maintain the cleared areas. This effort has reclaimed approximately 34 million cubic meters of water per year to the benefit of both people and the environment.
TNC is committed to accurately quantifying the impact of invasive trees on water resources in South Africa. This is achieved through the application of hydrological models and infield monitoring activities. During October 2019 – February 2020, six catchments around Theewaterskloof Dam, were instrumented with streamflow and rainfall monitoring equipment. The results of this hydrological monitoring represent a unique opportunity to provide measured evidence of the water benefits achieved through the clearing of invasive trees.
But we are learning that our monitoring activities can hit a snag due to potential equipment failures, storms, and wildfires, which pose risks to their success. To address these challenges, we upgraded the paired catchment monitoring stations in December 2024 through the support of Microsoft. A new telemetry system was installed, linking each piece of equipment via radio frequency and the mobile network. This enhancement significantly reduced the risk of data loss, improved accuracy, and supported the long-term resilience of the monitoring.
After almost six years of monitoring, we are frequently asked whether clearing invasive trees is increasing streamflow. Preliminary results suggest that reference (fynbos dominated) catchments exhibit, on average, a 34% increase in annual streamflow volumes compared to invaded catchments. This represents a significant amount of water, benefiting both people and nature in this beautiful region. We are excited about these incontrovertible findings as they provide concrete evidence of the benefits derived from the removal of invasive trees.
Restoring biodiversity to its original state may take a long time. However, I am just as excited about this moment. The fact that we can contribute every day to a matter of international importance is a gradual step to success.

The prospect of New Yorkers electing their first Muslim Mayor, come November, has ignited a rash of paranoid statements by right-wing US politicians, including Islamophobia– the irrational fear and hatred against Islam and Muslims.
Last week, a Republican politician caricatured America’s iconic Statue of Liberty wearing a burqa– an outer garment worn by some Muslim women that covers the entire body and face. But that internet meme, spreading across social media, was deleted after protests.
And another right-winger falsely warned that Zohran Mamdani, who last month won the Democratic Mayoral primary, may introduce the Islamic sharia law into the statute books of New York city’s five boroughs—with adulterers stoned to death in public.
If that punishment becomes a reality, one cynic jokingly predicted, New York may run out of stones—as once recounted about the fallout from Sharia law in a sandy Middle Eastern desert kingdom.
Meanwhile, President Trump, not surprisingly, jumped into the fray dismissing Mamdani as “a Communist lunatic.” That remark was a grim reminder of the spread of “McCarthyism” in the US in the early 1950s: a campaign against alleged Communists in the US government and other institutions.
Led by Senator Joseph McCarthy, the campaign, which falsely accused scores of politicians and Hollywood celebrities as “Communists”, was labeled the “search for reds under every bed”.
The 33-year-old Mamdani, a Democratic socialist and a social media star, is currently a member of the New York State Assembly from the 36th district, based in the New York city borough of Queens.
At the primary elections last month, he defeated Andrew Cuomo, the thrice-elected Governor of New York state. Mamdani’s father is a professor at the prestigious Ivy League Columbia University and his mother the celebrity award-winning movie producer Mira Nair.
Mamdani was born in Kampala, Uganda and his middle name Kwame was a tribute to Kwame Nkrumah, a political theorist and revolutionary, who served as Prime Minister of the Gold Coast (later Ghana) and President, from 1957 until 1966.
Mamdani migrated to New York City when he was seven years old and graduated from the Bronx High School of Science and later earning a bachelor’s degree in Africana studies from Bowdoin College.
Dr James E. Jennings, President, Conscience International, told IPS: “If New York is really a global city, having a Muslim mayor should be a welcome development. A quarter of the world’s population and almost 10% of New York’s citizens are Muslims. Where else but in the Big Apple could the United States better demonstrate our founding principles of liberty and justice for all? he asked.
First, the horror of September 11 fascinated the world, then New York’s most disreputable playboy took charge in Washington with global repercussions. Perhaps now an exemplary US citizen like Mamdani, who happens to be a Muslim, could lead our current politics in a more rational and moral way. His election might help repair frayed ties with the world’s 50 Muslim-majority countries and lead US politics out of its current anti-immigrant jingoism, said Dr Jennings.
Prejudice against Muslims, he pointed out, is hopelessly entangled with the politics of the Middle East. A clear voice like Mamdani’s is needed to speak out for justice and repudiate the “attack first” mentality of the Netanyahu-Trump cabal that keeps the US involved in unnecessary wars and fuels the Military-Industrial Complex (MIC).
“Those in New York’s Jewish community who deplore the Likud Party’s abandonment of Israel’s founding principles and repudiate the genocide in Gaza have apparently already decided to vote for the progressive candidate”, said Dr Jennings.
Ian G. Williams, President Foreign Press Association (FPA), told IPS Mamdani’s biggest electoral asset is that when asked, he answers questions directly and factually without looking over his shoulders to see what the funders and PACs think. (Political action committees and super PACs play significant roles in federal election campaigns by raising and spending money to influence elections.)
“No hedging, no pandering no Clintonesque squirming about what the meaning of “is” is. Voters will respect the courage even if they are not totally onside with the message”, said Williams former speechwriter for Neil Kinnock, whose speeches derailed Joe Biden’s 1988 Presidential run when he was caught out in unacknowledged plagiarism.
The turning point was when he fielded the “gotcha” question and redirected it against the other candidates paralyzed by fear of AIPAC (the American Israel Public Affairs Committee, a pro-Israel lobbying group in the United States.).
When asked about going to Israel, in effect, he challenged them to explain WHY a mayor of a city with so many problems would take time off to visit an Eastern mediterranean state committing war crimes. In many ways this was more effective than chanting on a stage at Glastonbury.
It is less than a lifetime ago that JF Kennedy’s candidacy was dubious because he was a Catholic. The bigots who evoked Zohran’s Muslim background while applauding applied dogma from Opus Dei in SCOTUS are irrelevant, declared Williams, a former President of the UN Correspondents’ Association (UNCA).
Dr Ramzy Baroud, a journalist and Editor of The Palestine Chronicle, told IPS the attacks on Mamdani, a principled man with a solid following among people who are seeking value-based politics, are a strange amalgamation of all the tropes of the past: those that accompanied the McCarthyism era, those pertaining to any criticisms of Israel, and those that preceded and intensified after the September 11, 2001, attacks.
“This hodgepodge of accusations, he said, lacks a central theme, though the real, often unstated fear is that Mamdani is a danger to the ruling classes, frankly on both sides. They are simultaneously accusing him of being a communist, an Islamist, a crazy person, and an antisemite, among a long list of ridiculous accusations”.
This reflects not only the overriding racism and foolishness that continues to control political discourse in the U.S., but also a degree of desperation, said Dr Baroud.
“The fallout of this madness is that they are repeating the same lines that many Americans are fed up with and no longer accept or tolerate. In other words, the attacks on Mamdani could very much be the reason behind his potential victory in the New York Mayoral race, which in turn will further elevate and make more meaningful the overall political discourse”.
The current level of so-called political debate is arguably the most debased in history, and it seems to be getting worse with time, where the president of what is supposed to be one of the greatest democracies in the world is making physical threats to arrest and deport popular politicians for disagreeing with him. This will bode very badly for the future in the country, thus highlighting the need for Mamdani-like politicians, declared Dr Baroud.
Norman Solomon, executive director, Institute for Public Accuracy and national director, RootsAction, told IPS a gradual trend of lessening racism and increasing anti-racism in the United States, especially among younger Americans, has been a major factor in making possible Mamdani’s primary victory.
Likewise, overall, a reduction of ethnocentrism and increasing affirmation of multiculturalism in urban areas – contrary to the very real racism and xenophobia led by Donald Trump – have opened the door to electoral progress by progressives who are not white and do not fall into the category of Judeo-Christian heritage.
This is all to the good for the health of the society, and all to the good for the prospects of victory for genuinely compassionate and forward-looking political leaders like Zohran Mamdani.
But the big backlash against Mamdani’s victory and what it represents has just begun, he warned. “This is a longstanding kind of reactionary bigotry that has always been a motor force for cruelty and systemic injustice in this country”.
Mamdani’s win is a highly encouraging event that could foreshadow great progress for social justice and against Islamophobia in the United States.
Yet the hostility that this progress has provoked tells us that powerful attitudes and forces for bigotry are surging to roll back essential progress, declared Solomon, author, “War Made Invisible: How America Hides the Human Toll of Its Military Machine”

Since the wake of the Sudanese Civil War in 2023, Sudan has faced a dire humanitarian crisis that has been marked by extreme violence, widespread civilian displacement, and an overwhelming lack of basic services in relation to the massive scale of needs. The latest reports from a host of United Nations (UN) organizations shed light on the rapid deterioration of living conditions for Sudanese internally displaced persons (IDPs) and refugees.
In March, the Danish Refugee Council (DRC) issued its Global Displacement Forecast Report, which detailed the projected trends in civilian movement for the remainder of the year. Sudan, which has been described as the world’s most dire displacement crisis, accounts for nearly one-third of new global displacements this year. It is estimated that by the end of 2026, an additional 2.1 million Sudanese civilians will be internally displaced.
According to the latest Displacement Tracking Matrix (DTM) report from the International Organization for Migration (IOM), as of May 28, over 10 million civilians are currently internally displaced across all 18 states in Sudan. Roughly 7.7 million have been displaced since the wake of hostilities in April 2023 and have never returned home.
Additionally, IOM estimates that from June 26-29, approximately 3,260 households were displaced across several counties in the Bara locality of North Kordofan as a result of heightened violence. Over half of the displaced civilians reported were children under the age of 18-years old.
On June 29, the United Nations Children’s Fund (UNICEF) released a situation report detailing the escalation of hostilities recorded in May. Renewed clashes between warring parties were reported in the West Kordofan, South Kordofan, Khartoum, and North Darfur states, spurring nearly 100,000 new internal displacement cases. West Kordofan was hit the hardest as brutal clashes in the areas surrounding the An Nuhud and Al Khiwai towns drove roughly 60,415 people away from their homes.
According to the United Nations High Commissioner for Refugees (UNHCR), since April 2023, over 4 million Sudanese civilians have been forcefully displaced to neighbouring countries, with Egypt and Chad housing the largest numbers of refugees. In early April this year, UNHCR recorded numerous armed attacks on displacement camps in North Darfur, including the Zamzam and Abu Shouk shelters, which further spurred mass movements to Chad.
Doctors Without Borders (MSF) states that since April, over 80,000 Sudanese refugees have crossed into Chad, with approximately 68,556 being concentrated in the Wadi Fira and Ennedi Est provinces. As of June, there has been a daily average of 1,400 Sudanese civilians crossing into Chad.
UNICEF reports that despite the new surges of heightened insecurity, May saw an overall reduction in displacement, with roughly 1.1 million civilians returning to their sites of origin, most being recorded in Al Jazira. However, the vast majority of these individuals still struggle with risks of violence and an overwhelming lack of essential resources, such as food, shelter, healthcare, and water and hygiene (WASH) services.
UNHCR interviewed roughly 6,810 of the refugees in Chad. They found that nearly 60 percent of them had been separated from their families, and 72 percent reported experiencing severe human rights violations, including physical and/or sexual violence, arbitrary detention, and forced recruitment.
Additionally, Sudanese refugees and IDPs alike face heightened risks of food insecurity. According to UNICEF, over 17,766 children in Sudan were diagnosed with severe acute malnutrition. In Uganda, the World Food Programme (WFP) estimates that Sudanese refugees are relying on 500 calories per day, only roughly a quarter of the daily needs per person. In Chad, nutritional support has been stretched to its limits and food rations are to be significantly reduced in the coming months unless additional funding is secured soon.
“This is a full-blown regional crisis that’s playing out in countries that already have extreme levels of food insecurity and high levels of conflict,” said Shaun Hughes, WFP’s Emergency Coordinator for the Sudan Regional Crisis. “Millions of people who have fled Sudan depend wholly on support from WFP, but without additional funding we will be forced to make further cuts to food assistance. This will leave vulnerable families, and particularly children, at increasingly severe risk of hunger and malnutrition.”
Due to limited access to WASH services and healthcare for the majority of Sudanese IDPs, there have been 23,000 new cases of cholera declared this year. With cumulative cases exceeding 73,000, UNICEF warns that the health situation in Sudan is projected to deteriorate significantly as the upcoming rainy season approaches.
According to UNHCR, of the Sudanese refugees in neighbouring countries, children bear the brunt of the crisis. It is estimated that 66 percent of refugee children lack access to educational services and roughly 30 percent have sustained serious injuries.
“(My son’s) hand got ripped off by a shrapnel bomb, some got stuck in his right eye. He arrived at the MSF clinic in (Chad’s) Tine camp several weeks ago. Each time, doctors and nurses struggled to even access the wound as the child was traumatized and in immense pain,” said the mother of Mahanat, an eleven-year-old Sudanese refugee who fled to Chad after an April attack on the Zamzam camp in Sudan, in an interview with MSF.
UNHCR states that only 14 percent of humanitarian needs for Sudanese refugees have been met, leaving thousands particularly vulnerable to extreme weather events, adverse health conditions, and violence. It is estimated that the average Sudanese refugee receives roughly 5 liters of water per day, which is about 4 times less than the global average per person.
“Again, we ask donors, the UN, and humanitarian organizations to start providing or scaling up support in terms of food, shelter, sanitation, and medical care, including mental health services,” said Claire San Filippo, MSF’s emergency coordinator for Sudan. “The current response is grossly insufficient.”

UNITED NATIONS, Jul 3 2025 (IPS)
The UN has been criticized by some member states for overstepping the mandate of its Responsibility to Protect (R2P) doctrine during a debate in the General Assembly.
United Nations member states held another General Assembly meeting to discuss the 20-year-old doctrine Responsibility to Protect, where many powerful members spoke out against the political contract.
On Tuesday, July 1, the General Assembly invited United Nations member states to resume discussion about Responsibility to Protect (R2P), the doctrine meant to prevent crimes against humanity. Previously, many member states spoke in support of the doctrine, calling for countries to reaffirm their commitment to protecting civilians and to respect the rulings of international law. Although some states speaking shared this sentiment, other powerful representatives advocated emphatically against R2P, criticizing its inefficacy and calling for its removal.
The Representative from the Russian Federation was a particularly strong critic of R2P, calling it “an instrument used repeatedly by the collective West to interfere in the internal affairs of states to replace humanitarian intervention.” Russia particularly noted the first use of R2P in 2011 during Libya’s civil war, condemning the West’s “warped interpretation” of the provisions in R2P.
This criticism is not uncommon: experts have argued for years that the UN overstepped its mandate outlined in R2P by authorizing military intervention.
In line with R2P, the Security Council 1973 authorized the protection of civilians “by necessary measures.” This broad statement gave NATO powers the freedom to enter the conflict territory with troops. Russia was among five abstentions for Resolution 1973, alongside China, a fellow permanent member, Brazil, Germany and India.
Calling the UN and NATO’s actions in Libya an “act of aggression against a sovereign state,” Russia went on to criticize the International Criminal Court (ICC), what it called “an instrument of the collective West.” Accusing the ICC of destroying a “once-prosperous Arab country,” Russia condemned R2P, humanitarian intervention and the ICC as neocolonial tools to maintain Western dominance globally.
The Representative from the United States of America also criticized R2P, but for very different reasons. Calling it a dangerous concept that “opens the door to selective, politicized action under the guise of humanitarian concern,” the US called the doctrine “destabilizing” to “the very international order it claims to uphold.”
Noting that intervention in conflict often is not in a state’s individual interest, the US claimed the vague concepts of collective responsibility in the document were not effective in addressing all atrocities. Using examples of China’s treatment of the Uyghur population, the military regime in Myanmar and the current conflict in Sudan, the US said, “Some Member States must do much more to address the risks that lead to atrocities and to put an end to senseless conflicts.”
This comes at a time when UN human rights experts have criticized “the United States’ escalating attacks on the international architecture of human rights, the rule of law, multilateralism, the principles of sovereign equality and self-determination, and vital international agreements on peace and security, climate change, global justice, and international cooperation.” Many states fear America’s growing isolationist practices, while others like Russia worry that they, like other Western states, are too involved in the sovereignty of other states.
The representative reiterated, “The United States will always act in accordance with our national interest and will not subordinate our sovereignty to shifting international norms, and we encourage others to do the same.” Naming R2P as a political commitment rather than a legally binding one, he suggested that each individual state protect its own populations from genocide, war crimes and crimes against humanity as the doctrine lays out.
Such influential member states, both of which are permanent members of the Security Council, undoubtedly have significant sway in the UN. However, several smaller states maintained support for R2P while outlining ways it could be improved.
The Representative from Ghana called R2P’s issue a “crisis of confidence” in implementation, arguing that its failures must be addressed by a reiteration of political commitment and a refusal to look away when the truth is inconvenient. Ghana emphasized a responsibility to remember the doctrine’s failures, including Libya, while moving forward to improve it as a more effective tool. He said, “when we preserve the truth of past atrocities, honor the memory of victims and confront denial, we are strengthening the foundations on which R2P stands.”
The future of R2P is unclear. Whether states will join the calls of larger states like the US and Russia, calling for the doctrine’s end, or whether they will, as Ghana said, reaffirm shared humanity with the principle, the decision will undoubtedly affect the normative culture of multilateral action in the face of humanitarian crises.
