ROME, Jul 24 2026 (IPS)

After two days of debate at an international conference devoted to the challenges of artificial intelligence (AI), nuclear war and global security, Nobel laureates, former heads of state and government, scientists, human rights defenders, religious leaders and representatives of civil society adopted a joint declaration, calling for it to be based on human dignity.

Inspired by Pope Leo XIV’s encyclical Magnifica Humanitas and signed in the halls of the Capitol, Rome’s city hall, this text states that artificial intelligence cannot be left solely to military or commercial interests. It also calls for international cooperation based on human dignity, the development of global AI governance and the continuation of efforts towards nuclear disarmament.

As major powers are investing increasingly substantial sums in the development of AI, participants considered that humanity stands at a genuine crossroads. The choices that will be made will have a decisive impact not only on tomorrow’s geopolitical balances but also on the future and place of human beings in a world where decisions could increasingly be entrusted to artificial intelligence.

This point was highlighted by Rome’s mayor, Roberto Gualtieri, the master of ceremonies of this meeting, organised by the Global Nobel Laureates Assembly on Artificial Intelligence and Nuclear War, who described it as historic.

The declaration, named “The Rome Declaration for a Disarmed and Disarming Peace”, was signed on Thursday, July 16.

For Rome’s mayor, “the crucial issue, both at the global and local levels, is technological development, which must be inspired by fundamental ethical principles: respect for individuals, equality among human beings and democratic responsibility in the name of the common good.”

Gualtieri also stressed that today, more than ever, “the world needs an international coalition capable of promoting a new model of development combining economic growth, social justice, human rights and environmental protection”, thus echoing Pope Leo XIV’s call for “a disarmed and disarming peace”.

A few hours earlier, Agnès Callamard, secretary general of Amnesty International, had warned against the development of autonomous weapons.

“The idea that decisions to kill could be made by machines is repugnant to us.”

According to Callamard, the danger does not lie in an artificial intelligence that would suddenly become conscious but rather in the decision to delegate to it responsibilities that belong exclusively to moral judgement.

“It is not that the machine decides that it will become the boss; it is we who programme these systems,” she explained.

For the head of Amnesty International, the growing integration of AI into military operations represents a major change. These systems can already analyse enormous quantities of data, identify targets and recommend strikes, while gradually reducing the need for human intervention.

Beyond autonomous weapons, the Callamard reminded the world that it must pay close attention to the implications of the progressive integration of AI into what the military calls, in its jargon, the “kill chain”, meaning the process from target identification to the conduct of an operation.

“Even when a human being officially retains the final decision, the growing dependence on automated systems profoundly changes the way military operations are prepared and conducted,” Callamard stated, adding that these technologies rely on immense volumes of data that may themselves be altered.

“Analyses and recommendations can be biased because they are based on data that themselves carry these biases. We must remain attentive to the risks arising from erroneous or discriminatory decisions in contexts where the consequences can be irreversible.”

Another danger: the multiplication of force. Thanks to artificial intelligence, a single operator could simultaneously supervise dozens, or even hundreds, of drones or other autonomous systems, considerably increasing military capabilities.

“These technological developments are taking place within a broader context of strategic competition between states. We are living in a period when many governments are seeking military hegemony,” Callamard concluded.

Beyond military issues, several speakers also insisted on the geopolitical consequences of this technological revolution. Romano Prodi, former president of the European Commission and former Italian prime minister, estimated that the growing rivalry between the United States and China considerably complicates the emergence of genuine international regulation.

In an increasingly fragmented world, Prodi warned, no nation will be able to address alone the challenges linked to artificial intelligence, global security or the control of ever more powerful technologies.

These words anticipated the essence of the final declaration, according to which international cooperation is now an indispensable condition for preventing artificial intelligence from fuelling a new arms race and widening geopolitical fractures.

The discussions also focused on the economic and social consequences of this technological revolution. In the world of work, the sudden arrival of AI is already raising many concerns, particularly regarding the professional future of younger generations and the profound transformation of several professions in the coming years.

The programme brought together a number of leading international figures, including Nobel Peace Prize laureate and former Chief Advisor to Bangladesh Muhammad Yunus; Yoshiyuki Nagaoka, Executive Director of the Office of Public Affairs at Soka Gakkai; Filipino journalist and Nobel Peace Prize laureate Maria Ressa; Amnesty International Secretary General Agnès Callamard; and several scientists and nuclear experts.

Research published by King’s College London shows that a study carried out on hundreds of millions of job advertisements across 39 countries reveals an average 6.1% decline in job offers in professions most exposed to automation, while the remaining positions require increasingly specialised skills.

Ultimately, what will remain of this conference and of the Rome Declaration? The main point to remember is that participants accept the development of artificial intelligence and do not believe it should frighten us. On the contrary, they consider that this technology can become a powerful driver of progress – provided, however, that it remains at the service of humanity. The ball is therefore in the court of states and their leaders, who must above all place human dignity at the forefront.

The real question is no longer only what artificial intelligence will make possible, but rather what limits societies and humanity as a whole will choose to set for it before the imperatives of power permanently override collective responsibility.

UNITED NATIONS, Jul 24 2026 (IPS)

With regional friction between Iran and the Gulf monarchies escalating, Houthi leadership in Yemen has proclaimed a total maritime blockade against all vessels linked to Saudi shipping. While this declaration does not constitute a verified military obstruction of the Bab el-Mandeb Strait, it significantly heightens the risk of volatility at the Red Sea’s southern gateway, potentially severing the primary arterial link to the Suez Canal.

The embargo is already being framed as more than a simple ban on Saudi-flagged vessels. In messages sent to shipping companies navigating the Strait, the Houthis warned against any activities at Saudi ports, including by non-Saudi-flagged ships, saying that vessels could be targeted “in any location.” This is significant as Saudi Arabia’s maritime infrastructure managed 331 million tonnes of freight in 2024—a volume roughly equal to 12 million fully laden 20-foot containers.

Within days of these threats being made, five ships have been recorded turning around after heading towards the Bab el-Mandeb passage. Among these ships, the Xin Long Yang, a VLCC loaded at Yanbu and bound for Qinzhou, China, carrying 2 million barrels of Saudi crude, initially reversed north towards the Suez Canal. The vessel later reversed course again, choosing to resume its original route heading south towards Bab el-Mandeb.

Additionally, Houthi military spokesperson Yahya Saree said that two Saudi oil tankers, named Encelia and Layla, were targeted for their “violation of the blockade decision issued by the armed forces.”

Jeddah Islamic Port, the Kingdom’s principal commercial gateway on the Red Sea, received 3,805 vessel calls in 2024, more than any other Saudi port. Yanbu has become Saudi Arabia’s critical Red Sea oil-export network, where crude is moved from eastern fields using the East–West pipeline before being loaded onto tankers. With the Strait of Hormuz severely disrupted, the Red Sea corridor is no longer simply an alternative route: it is Saudi Arabia’s critical remaining maritime outlet to Asian markets.

Saudi Arabia’s Yanbu port was loading approximately 4 million b/d in mid-July, close to 4 percent of daily global oil demand. Disruptions at Bab el-Mandeb would also affect the Suez Canal, which carried approximately 22 percent of global seaborne container trade in 2023 and acts as the link between European and Asian markets. Of the cargo which transits through Bab el-Mandeb, 3.97 million b/d of crude passed through its gates in March, according to Kpler.

If the Houthis can continue to enforce their threat and create enough uncertainty, even selective attacks on some vessels can increase wartime insurance costs and undermine security guarantees, which could push carriers to reroute around the Cape of Good Hope at the southern tip of Africa.

For an Asia–Europe container voyage, rerouting around the Cape of Good Hope can add roughly 3,000 to 3,500 nautical miles and approximately seven to ten days of sailing time. This also increases the cost of the voyage, heightening fuel costs, requiring more vessel capacity to maintain scheduled services, and exposing cargo to higher insurance premiums. The World Bank has estimated that the additional fuel bill alone could reach USD 1 million for a round trip. Analysis by the OECD put the wider cost increase at USD 1.7 million for a medium-sized container ship on an Asia–Europe round trip—roughly an increase of USD 272, or 19 percent, for one standard 40-foot container.

In late 2023, similar Houthi threats, which led to selective attacks against commercial vessels, led major carriers to avoid the Red Sea passage and use the alternative route around the Cape of Good Hope. In just three months, by mid-February 2024, UNCTAD had recorded 586 container vessels taking the longer route around Africa, while container tonnage moving through the Suez Canal had simultaneously fallen 82 percent. Spot rates—the price of booking a container on short notice—also rose by 256 percent during the same period on voyages from Shanghai to Europe.

For Yemen, the consequences could be especially severe. The country relies on imports for more than 90 percent of its staple foods, including about 90 percent of its wheat and all of its rice requirements. Much of that supply enters through the ports of Aden and Hodeidah. The World Food Programme estimates that 18.2 million people in Yemen require humanitarian aid, being in dire need of humanitarian assistance and protection services.

Even considering that the Houthis formally exempt humanitarian cargo from the embargo, an escalation of insecurity can delay vessels and raise freight and insurance costs, deterring commercial shipping lines from calling at Yemeni ports. Humanitarian aid will not be nearly enough to replace the normal commercial flow of food and fuel, which affects Yemeni civilians first, who are already facing hunger and economic collapse.

The central question is not whether the Houthis can permanently seal Bab el-Mandeb. It is whether they can make the route risky enough that insurers, carriers, and oil traders abandon it themselves.

Investments in jobs, basic services and community infrastructure can reduce the pressures that drive displacement in Myanmar. Credit: UNDP Myanmar

By Norimasa Shimomura
YANGON, Myanmar, Jul 24 2026 (IPS)

When asked what development looks like today, a community leader in Kalaw township points to these fields. Once destroyed by a typhoon, they are now productive again. What began as emergency food assistance in the first month was followed by UNDP support in the community—seeds, training, debris removal, support to microbusinesses and small infrastructure—backed by the Republic of Korea, Norway and Switzerland. One year on, the fields sustain three annual production cycles—rice and flowers—with more resilient practices and higher yields. “This is what development looks like to us,” he says.

Communities in Myanmar today are not facing a single crisis. They are facing many, and layered on top of one another, recurring over time. Conflict, insecurity, economic uncertainty, market volatility and climate- and disaster-related shocks do not occur in isolation. Global crises are placing added pressure on already-stretched humanitarian and development financing. Together, these dynamics reinforce one another, creating a cycle that is harder to break. These protracted, compounding crises are reshaping the country’s social and economic fabric and putting communities under enormous stress.

Myanmar shows why separating humanitarian action from development no longer fits reality. Relief keeps people alive, but it will not on its own restart livelihoods, steady local services, increase risk preparedness or reduce the pressures that drive displacement. The smarter play is to link emergency support to a continuum of recovery, stabilization and longer-term development, backing community systems and local markets so today’s spending also buys a more durable future.

A crisis that feeds on itself

Myanmar is fragmented: conflict in too many areas, economic freefall in others, and climate shocks across the country—from floods and droughts to rising temperatures and environmental loss. But these pressures are connected. When livelihoods collapse, people move. When insecurity rises, local economies contract. When disasters hit, already-fragile services give way. Families then face hard trade-offs; taking on high-interest debt, moving to precarious urban fringes, attempting risky migration, or turning to illicit markets.

For many, participation in informal, and sometimes criminal economies is less a choice than a last resort. Others flee, often towards cities such as Yangon. But urban areas are already under strain. In peri-urban Yangon, poverty rates are estimated to be around 50 percent, and new arrivals stretch housing, services and jobs further, deepening vulnerability and inequality. Women shoulder this burden most heavily, with women-headed households in peri-urban areas more likely to have lower incomes, depend on precarious and poorly paid employment, and facing heightened safety concerns.

This is how the crisis sustains itself. Conflict and violence breed insecurity; insecurity forces people from their homes and pushes some into illicit economies; displacement fractures livelihoods and the resulting economic hardship reinforces instability. And so the cycle continues.

The limits of a humanitarian-only response

Myanmar has received humanitarian aid for decades. It remains essential. People need immediate support for food, shelter and protection. But the challenges Myanmar faces today are not only humanitarian. They are structural and long-term. When support can only be planned and financed in short cycles, it can help people survive, but without enabling them to rebuild livelihoods, restore services or reduce future risk. This can create dependence on humanitarian aid without a clear exit.

The question is no longer whether humanitarian support is needed—it clearly is—but whether it is sufficient on its own, and how development can help build resilience. To break the cycle, investments must also focus on recovery, livelihoods, risk preparedness, access to finance and local systems. The bridge between humanitarian action and development must be deliberately built. UNDP in Myanmar has designed a new phase of its Community First Programme backing community-led solutions that can absorb shocks now while laying foundations for medium- and longer-term development.

Where the bridge matters most

There are three areas where this bridge is critical.

By combining community-based approaches with more targeted economic interventions, it is possible to offer a more comprehensive response in a protracted crisis. Credit: UNDP Myanmar

First, livelihoods and early recovery. Investments in jobs, basic services and community infrastructure can reduce the pressures that drive displacement. When people have viable ways to earn a living, they are less likely to move out of necessity. This also reduces the burden on humanitarian systems and can be an immediate stabilizing factor.

Second, local systems and community capacity. Even in constrained contexts, support to community-level structures can have a powerful effect. It enables people to manage their own recovery, strengthens local decision-making and builds a sense of ownership. It helps communities to think longer term and create some community wealth. These are the building blocks of future governance.

Third, economic alternatives to illicit activity. When large parts of local economies in some regions operate in grey or black markets, the implications go beyond livelihoods, they affect national and regional security. Creating alternatives—through job creation, support to small businesses and financing—gives people options. It reduces reliance on illicit networks, lowers risks of exploitation and opens pathways for more sustainable economic activity. These directly affect stability within Myanmar and across its borders.

Navigating a complex funding landscape

Despite the clear need to bridge humanitarian and development approaches, funding structures often work against it. In Myanmar, much of the available funding is still categorized as humanitarian. This creates challenges for organizations with strong development expertise, which must adapt their language and delivery models to fit short-term funding criteria.

At the same time, partner expectations are evolving, but not always consistently. Some continue to fund purely humanitarian outputs. Others expect development impact from humanitarian interventions. Still others fund development but want to demonstrate humanitarian impact.

This creates a fragmented landscape: humanitarian funding for humanitarian results, humanitarian funding seeking development impact, development funding framed as humanitarian and, more rarely, development funding investing directly in long-term results.

Navigating this requires flexibility and clarity of purpose. Development actors must be able to articulate the longer-term impact of their work, even when operating in a humanitarian context. The value lies precisely in that distinction: connecting immediate interventions to sustained recovery and future stability.

A window of opportunity

There are signs of change. Some partners are beginning to recognize that continued investment in short-term relief, without parallel investments in recovery and livelihoods, is not sustainable.

This creates an opportunity. By combining community-based approaches with more targeted economic interventions—jobs, enterprise development, access to finance, climate and energy solutions—it is possible to offer a more comprehensive response in a protracted crisis context, one that addresses both immediate needs and underlying drivers of crisis. But this window may not remain open indefinitely. As other actors reposition and global priorities shift, the space for shaping this agenda could narrow.

Looking ahead

Myanmar’s challenges are complex but the direction of response is clear. Humanitarian aid remains indispensable. But on its own, it cannot break cycles of crisis that are structural and self-reinforcing.

Bridging humanitarian action and development is how people regain agency. It is how communities stabilize. And ultimately, it is how countries begin to move beyond crisis—not just survive it.

Latin America and the Caribbean has the world’s most expensive healthy diet. Credit: Max Valencia / FAO

By Máximo Torero
ROME, Jul 23 2026 (IPS)

Hunger is falling across most of Latin America and the Caribbean. The region’s next challenge is harder: ensuring that everyone can afford a healthy diet, not merely enough calories to survive.

The regional hunger rate fell for a fifth consecutive year in 2025, reaching a record low of 4.8 percent, down from the pandemic peak of 6.1 percent in 2020. About 32 million people faced hunger, more than 1 million fewer than in 2024 and 7.5 million fewer than in 2020. Moderate or severe food insecurity, which includes people forced to skip meals or eat less, also fell to 22.9 percent, below its 2015 level of 23.4 percent. The region’s share of the world’s hungry has remained at about 5 percent for 15 years.

This progress was not accidental. It reflects sustained investment in agricultural productivity and stronger social protection, including the cash transfer and school feeding programs developed by Brazil and Mexico.

Poor roads, limited rail networks, inadequate cold storage, unreliable energy, inefficient markets and post harvest losses raise costs as nutritious food moves through storage, processing, transportation, wholesale and retail

The countries recording the largest gains differ greatly, but their policies reveal a consistent pattern. Brazil, Chile, Costa Rica, the Dominican Republic, Guyana and Uruguay have reduced hunger below 2.5 percent, the level below which the Food and Agriculture Organization of the United Nations reports the estimate simply as “less than 2.5 percent.” Since the mid 2000s, Peru has cut its rate from 17.9 to 5.7 percent; Bolivia, from 27.6 to 19.5 percent; Colombia, from 11.0 to 4.1 percent; and Panama, from 14.8 to 4.7 percent.

These findings, from the 2026 edition of The State of Food Security and Nutrition in the World, show that hunger falls when agricultural, economic and social policies reinforce one another. Social protection preserves purchasing power. Agricultural investment raises productivity. Rural infrastructure connects farmers to markets. School meals and cash transfers protect vulnerable families while creating demand for locally produced food.

The gains, however, remain fragile and uneven.

The 2026 Middle East crisis poses a less uniform threat here than in Africa or Asia. Latin America and the Caribbean produces more crude oil than it consumes, and some energy exporters could benefit from higher prices. But this regional average conceals the exposure of many Central American and Caribbean economies that depend heavily on imported fuels and remain vulnerable to rising energy, fertilizer, transportation and food import costs. The crisis will create winners and losers within the region, not leave it untouched.

The sharpest divide is in the Caribbean. Its hunger rate edged up to 16.6 percent in 2025, nearly five times the rate in South America, while moderate or severe food insecurity reached 52 percent, the highest of any subregion.

Haiti is the most extreme case. Its hunger rate rose from 47.7 to 51.4 percent, and more than half the population faces acute food insecurity. Haiti is the only country in the Americas, and one of five globally, where people face catastrophic levels of hunger. Armed violence, institutional breakdown, economic decline and climate shocks are erasing years of development, even without a formally declared war.

But hunger captures only one dimension of deprivation. The cost of a healthy diet reveals a larger structural problem.

Latin America and the Caribbean has the world’s most expensive healthy diet. In 2025, it cost an average of 4.91 purchasing power parity dollars per person per day, compared with 4.35 in Africa, 4.33 in Asia and 3.64 in Northern America and Europe. In the Caribbean, the cost reached 6.04 purchasing power parity dollars, the highest of any subregion, compared with 4.66 in Central America.

Because regional incomes are higher on average, the share of people unable to afford a healthy diet, 25.7 percent, remains far below Africa’s 66.1 percent and has been declining since 2021. But averages again conceal severe deprivation. In Haiti, 88.9 percent of people cannot afford a healthy diet.

Latin America and the Caribbean has therefore made genuine progress against calorie deprivation. But sufficient calories are no longer its only, or even its largest, food challenge. A diet that prevents hunger does not necessarily prevent anaemia, child stunting, obesity, diabetes and other forms of malnutrition. A healthy diet requires adequate fruits, vegetables and animal source foods, yet that diet costs more here than anywhere else.

The region’s high diet costs are driven particularly by vegetables and by what happens after food leaves the farm. Poor roads, limited rail networks, inadequate cold storage, unreliable energy, inefficient markets and post harvest losses raise costs as nutritious food moves through storage, processing, transportation, wholesale and retail. This is not simply a production problem. It is a midstream problem.

The policy response must therefore be more precise than simply spending more on agriculture. Broad farm subsidies will not repair broken supply chains. Governments should invest in horticultural productivity, rural roads, rail connections, cold chains, storage, packhouses, reliable energy, wholesale markets and competitive transportation. These investments would reduce losses, expand supply and lower the price of fruits, vegetables and other nutrient rich foods.

Sequencing also matters. Expanding school meals, cash transfers or food vouchers before supply can respond may raise local prices and exclude the consumers these programs are intended to support. Investment in production and supply chains must precede, or at least accompany, measures that stimulate demand.

A decade ago, Brazil, Peru, the Dominican Republic and Colombia might have appeared to be unrelated success stories. We now know that their gains came from deliberate investments in social protection and agricultural productivity.

Making healthy diets affordable will require the same determination, directed this time toward the infrastructure, logistics and markets that move nutritious food to consumers. The immediate priority is to extend the region’s progress to the Caribbean and, most urgently, to Haiti.

Latin America and the Caribbean has shown that hunger can fall. It must now prove that a healthy diet need not remain a privilege.

UNITED NATIONS, Jul 23 2026 (IPS)

Prior to the latest round of hostilities between the United States and Iran, freight traffic had been increasing in the Strait of Hormuz, and negotiations were underway for a new agreement to fully restore trade through this channel.

According to UN Trade and Development (UNCTAD), energy markets were likely to bounce back to normal pre-conflict levels faster than that of food, public finance, and transport, leaving many vulnerable economies worse off. UNCTAD research shows a change from about 125 daily ship transits through the Strait of Hormuz in 2026, January 1st through February 27th, to a drop of around 10 daily transits from February 28th through June 14th during the conflict, marking a 92 percent decrease in overall transit ability.

According to UNCTAD and the Strait of Hormuz monitor, levels on June 2nd recorded around 40 ship transits, with an average of 60 through the days after signing the MOU (The Memorandum of Understanding signed by both US and Iranian delegations). This represents roughly half of pre-conflict transit levels.

Note: Daily outbound shipments represent AIS-traceable crude oil tanker departures from the Strait of Hormuz to destinations outside the Persian Gulf. Additionally, this graph is roughly similar to overall shipments of LNG, fertilizer, and Agricultural products through the same period.

Following the closure of the Strait, the daily price of crude oil jumped to USD 120 per barrel, then averaged around USD 100 per barrel throughout the conflict. The daily price of crude oil fell to USD 70 per barrel upon the signing of the MOU, roughly returning to pre-conflict levels. However, following the latest escalations and the breaking of the MOU, crude prices have risen again to approximately USD 100, indicating that agreements to cease conflicts can quickly bring prices down significantly, if agreed to once more.

On the contrary, the IGC Grains and Oilseeds Freight index (GOFI), indicates a slow decrease of the heightened costs of transporting both grains and oilseeds by sea (e.g., Wheat, Corn, Barley, Sorghum, Soybeans, Rapeseed (canola), Sunflower seed), across 68 key exporting origins in the regions of the United States, The European Union, Canada, the Black Sea region, Brazil, Australia, and Argentina.

Source: Author’s visualizations using data from the International Grains Council (IGC).
Note: The index is normalized so that 100 represents the average grain and oilseed freight rate on January 1, 2013. During the conflict, the index rose to approximately 190, representing a 90 percent increase relative to the base value and a 30 percent increase from the beginning of the conflict on February 28, 2026.

As a result of the heightened price of grains and oilseeds, among other agriculture components, UNCTAD says, “Past input price shocks remain a risk to future food security,” laying out the cycle in which costs can amount:

1. Traffic through the strait was disrupted.
2. Limited freight traffic constricts the availability and raises the cost of oil, gas and nitrogenous fertilizer.
3. A decrease in energy exports creates higher energy prices, increasing transport and shipping costs.
4. Further fuel inflation slows down the global economy.
5. Agricultural production costs increase.
6. Food production may be affected by the increased cost of agricultural components such as fertilizer, pushing domestic food prices further up.
7. Vulnerable populations may face greater food insecurity and hunger, as a result of the heightened cost of importing food, and domestic agriculture production.

This process has exposed 61 vulnerable economies to dual impact of higher oil and cereal import prices. (e.g., wheat, rice, corn, barley, oats, sorghum, millet, rye) These countries consist of 35 least developed countries and 26 small island states, with seven of those countries being both least developed and small island developing states.

According to UNCTAD, the pressure is “sharpest for economies that rely heavily on imported fuel”, citing an example in Cabo Verde where net imports of oil and petroleum products averaged 24.6 percent of GDP within recent years. This dependence on fuel imports means that those extra costs can quickly make food prices, electricity, transport, and public finances more expensive.

Notes: Orange countries are small island states, and blue countries are least developed countries (LDCs).

Yemen was also cited to be at high risk, with analysis showing that net imports of cereal and cereal products averaged 10.8 percent of GDP. For countries like Yemen dealing with conflict, hyperinflation, debt pressure, and limited public financing, a higher import bill for grain compounds an already declining situation.

Notes: Orange countries are small island states, and blue countries are least developed countries (LDCs).

UNCTAD analysis indicates that a real increase of food cost by just 5 percent is associated with a higher risk of child wasting (a life-threatening form of acute malnutrition), especially among poor children and children living in rural landless households.

While restoring full trade through the strait is a necessary step to recovery, this will not undo the aftermath that higher import bills, delayed shipments, and higher priced food and energy have on the global economy, especially vulnerable economies.

“The policy task is therefore broader than reopening a route. Vulnerable economies need support to manage higher import bills, protect households from food and fuel shocks, and invest in systems that reduce exposure before the next disruption hits household budgets,” said UNCTAD, indicating the importance for vulnerable economies to develop supply chain resilience, sustainable systems, and have less reliance on concentrated international trade for vital goods such as food and energy, among financial support from the international system.

Every morning, as the Indian Ocean retreats from the reef off Zanzibar’s Jambiani village, Chiku Chande steps into the knee-deep lagoon carrying bundles of seaweed seedlings. Years of farming these waters have taught her about every channel and coral outcrop. But lately, the corals that once glowed in brown and gold have become chalky white.

“You don’t need anyone to tell you these changes,” Chande tells IPS. “We see it with our own eyes. The coral has lost its colour.”

Like many families in Jambiani, the 48-year-old grandmother depends on the reef. It shelters her seaweed farm from crashing Indian Ocean waves, supports fish stocks and brings tourists to the village. As the corals bleach and slowly die, she worries about the future.

Chande has watched the reef change year after year. Scientists say her observations mirror what is happening across the world’s tropical oceans.

Scientists long regarded El Niño – the natural warming of parts of the Pacific Ocean that disrupts weather patterns globally – as the main driver of mass coral bleaching

A new study led by Climate Central and published in Oceanography concludes that human-induced climate change has driven every global coral bleaching event over the past four decades. The researchers found greenhouse gas emissions have warmed the oceans so much that El Niño now acts mainly as a trigger rather than the root cause.

“Our study shows that without climate change, coral bleaching would be a rare and isolated event, and global mass coral bleaching simply would not occur,” says Andrew Pershing, Climate Central’s chief programme officer and the study’s lead author.

Corals bleach when unusually warm water forces them to expel the microscopic algae that provide most of their food and give them their vibrant colours. If temperatures quickly return to normal, corals can recover. But prolonged heat starves them and can kill entire reef ecosystems.

To determine how much of that warming came from human activity, researchers compared today’s sea surface temperatures with computer simulations of a world unaffected by greenhouse gas emissions. They then assessed whether bleaching would still have occurred under those cooler conditions.

Their analysis showed that every global bleaching event since 1998 – including those in 1998, 2010, 2014-2017 and the ongoing event that began in 2023 – required human-caused warming to push ocean temperatures beyond bleaching thresholds. Although El Niño coincided with many of those events, the study found they would not have become global bleaching episodes without decades of warming driven by fossil fuel emissions.

The findings have particular implications for Tanzania.

The country’s 1,400-kilometre coastline, which includes the reefs surrounding Zanzibar, Pemba and Mafia islands, supports fisheries, tourism and thousands of coastal livelihoods. Healthy reefs also protect beaches and coastal settlements by absorbing up to 97 percent of incoming wave energy, reducing erosion and storm damage.

As reefs deteriorate, fish populations decline, tourism suffers and coastlines become increasingly vulnerable to flooding and erosion.

Similar pressures are happening across tropical reefs worldwide. Although coral reefs cover less than one percent of the ocean floor, they support roughly a quarter of all marine species and generate an estimated US$2.7 trillion annually in ecosystem services through fisheries, tourism and coastal protection. The Global Coral Reef Monitoring Network estimates the world lost about 14 percent of its coral between 2009 and 2018 as repeated marine heatwaves left reefs too little time to recover.

Recent ocean temperature records suggest the pressure is intensifying.

According to the Copernicus Marine Service, June 2026 was the warmest June on record for global sea surface temperatures, while marine heatwaves covered about 82 percent of the world’s oceans by the end of the month. Because the oceans absorb more than 90 percent of the excess heat trapped by greenhouse gases, marine heatwaves are becoming more frequent and severe, increasing the likelihood of coral bleaching.

The Climate Central researchers project that by 2028 human-caused warming will outweigh El Niño’s influence in every coral reef region worldwide. Bleaching, they say, will increasingly reflect persistently warmer oceans rather than unusually strong natural climate cycles.

Using the same attribution methods, the researchers also assessed bleaching risk during the developing 2026-2027 El Niño. They found that while the climate pattern could still trigger bleaching in some regions, human-caused warming would account for most of the risk, particularly in the southern Caribbean, the Pacific coasts of Central and South America, and parts of East and Southeast Asia.

Globally, the monthly average sea-surface temperature for the extra-polar ocean (60°S–60°N) was the highest for June, exceeding the previous record set in June 2024 by just 0.01ºC.

The study challenges the long-held assumption that bleaching is mainly a response to natural climate cycles. Researchers say bleaching can no longer be viewed as an occasional event linked to natural climate cycles; scientists say it is increasingly becoming a recurring consequence of steadily warming oceans.

“By isolating the effect of climate change, our study shows that the fate of reefs is closely tied to how much carbon pollution goes into the atmosphere. Protecting reefs from overfishing and pollution is very important. We need as many thriving reef areas as possible. Even during severe events, there are often pockets of coral that persist. These areas can be the source for recovery in the short and long term,” Pershing tells IPS

The Intergovernmental Panel on Climate Change warns that even if global warming is limited to 1.5 degrees Celsius above pre-industrial levels, up to 90 percent of the world’s coral reefs could disappear by mid-century. At 2 degrees Celsius of warming, losses could reach 99 percent.

Chande does not speak in terms of climate attribution. She only knows the reef looks different from when she began farming seaweed. Researchers say the bleaching she has witnessed reflects a much deeper shift: oceans that have steadily warmed over decades because of greenhouse gas emissions.

“When I was younger, the corals were full of colour and fish,” she said. “Now everything looks white. I worry about what is happening to the sea,” she says.
