The landslides in Wayanad, a tourist-friendly district in the southern Indian state of Kerala, are rapidly becoming one of the most devastating natural disasters the region has ever seen. Entire areas in Chooralmala and Mundakai villages have been washed away, with local media reporting the destruction of over 250 homes. Tragically, the death toll has surpassed 280, marking a grim chapter in the region’s history.

The disaster, the worst since the devastating floods of 2018, has left a heart-breaking trail of destruction. Haunting images reveal uprooted trees, homes reduced to rubble, and bridges shattered, all swallowed by muddied waters. Each scene tells a story of loss, despair, and the enduring resilience of those affected.

Nestled in the rugged terrain of the Western Ghats, Wayanad is renowned for its stunning vistas and is a cherished tourist destination, attracting over 100,000 visitors each year. This picturesque district, home to indigenous tribes and dotted with lush tea and cardamom estates, holds a unique charm. Yet, beneath its beauty lies a history of vulnerability to landslides.

A 2011 report by a panel of experts led by ecologist Madhav Gadgil classified the entire Wayanad region as “fragile, medium fragile, and less fragile,” highlighting its susceptibility to landslides. This designation underscores the delicate balance of this ecologically sensitive area, where the enchanting landscape masks the underlying risks faced by its resilient inhabitants.

In the past decade alone, landslides have claimed the lives of 255 people in Kerala. In 2018, 109 people died in landslides, and in 2020 and 2021, around 182 lives were lost to these disasters. August 2020 saw a particularly deadly landslide in Pettimudi, which resulted in 66 fatalities.

Understanding Landslides

Landslides, also known as landslips, encompass a dramatic and diverse array of ground movements that can reshape landscapes in an instant. These natural events, ranging from rockfalls and mudflows to slope failures and debris flows, occur across various environments. Whether cascading down steep mountain ranges, eroding coastal cliffs, or shifting underwater as submarine landslides, these movements highlight the dynamic and unpredictable nature of the terrain. As communities and scientists grapple with their impacts, the stories behind these powerful geological forces continue to unfold.

While gravity is the main force behind landslides, various factors influence slope stability, creating conditions that make a slope vulnerable to failure. Often, a specific event like heavy rainfall, an earthquake, or construction activity triggers a landslide, though the precise cause isn’t always identifiable.

Human activities often exacerbate landslides. Urban sprawl, mining, and deforestation contribute to land degradation, reducing soil stabilization by vegetation. Additionally, global warming and other environmental impacts increase the frequency of extreme weather events, further triggering landslides.

The Catastrophe in Wayanad

Mundakai, the epicentre of a series of landslides, received 572 mm of rain in 48 hours. According to the India Meteorological Department, rainfall exceeding 204.4 mm per day is considered extremely heavy. Experts attribute the landslide in the Mundakai region to this heavy rainfall. In 2019, the Puthumala landslide occurred just two to three kilometres from the current disaster site.

Dr. S. Abhilash from the Cochin University of Science and Technology highlighted the region’s geographical vulnerability. He stated in a video shared on the university’s official Facebook page that heavy nighttime rain was the primary cause of the landslide.

The phenomenon, technically known as a mesoscale mini cloudburst, involves 15 to 20 cm of rain falling within two to three hours. Such events are now occurring in North Kerala, significantly impacting the region

In the past two weeks, the Konkan region (a stretch of land by the western coast of India) experienced heavy rainfall due to a low-pressure area from the Gujarat coast to North Kerala. North Kerala received 50 to 70 percent more rain than usual during this period, with areas including Wayanad recording over 24 cm of rain. The thickening of clouds in the southeast Arabian region contributed to this heavy rainfall.

This phenomenon, technically known as a mesoscale mini cloudburst, involves 15 to 20 cm of rain falling within two to three hours. Such events are now occurring in North Kerala, significantly impacting the region.

Mesoscale Cloudbursts and Kerala Floods

An earlier study published in Science Direct linked mesoscale cloudbursts to the 2019 Kerala floods. Researchers at the Advanced Centre for Atmospheric Radar Research (ACARR), Cochin University of Science and Technology (CUSAT), observed that rainfall exceeding 50 mm in two hours was reported in many places from 8 a.m. to 10 p.m. on August 8, 2019.

The Western Ghats, which run through Kerala, are prone to frequent landslides during the biannual monsoon seasons. The Gadgil Committee report classified areas like Kavalappara in Malappuram district and Puthumala in Wayanad district, which experienced fatal landslides in 2020, as Ecologically Fragile Land (EFL). Climate change exacerbates these issues.

Kerala has faced significant challenges due to climate change in recent years. The state endured a severe drought in 2015, followed by the devastating Ockhi cyclone in 2017. In 2018 and 2019, massive floods and landslides wreaked havoc.

The extreme rainfall of August 2019, which caused landslides and mudslides, leading to downstream flooding, was a ‘mesoscale cloudburst’—a rare phenomenon in Kerala usually seen in North India, according to the study published in ScienceDirect.

Given the increasing intensity of rainfall, the probability of landslides in the Western Ghats’ high to mid-land slopes during the monsoon seasons rises. Human intervention, primarily for crop cultivation, has altered the Western Ghats, making the region more prone to landslides of various scales.

Greece Passes Social Media Ban for Children Under 15

Greece’s new law will bar children under 15 from social media from January 2027, adding to international efforts to regulate young people’s access to online platforms.

Greece’s Parliament has approved legislation prohibiting children under 15 from using social media, with the restriction scheduled to take effect on January 1, 2027. The law requires platforms to verify users’ ages and provides for penalties if companies fail to comply.

The decision adds Greece to a growing international effort to regulate children’s access to social networking platforms, as governments respond to concerns about online safety, excessive screen use and children’s mental health.

Prime Minister Kyriakos Mitsotakis had announced the plan in April. His conservative New Democracy party used its parliamentary majority to pass the bill after a debate that continued from Thursday into Friday. The opposition PASOK party abstained, while other opposition parties voted against it.

How will the Age Restriction Work?

Social media companies will have to introduce age-verification systems to enforce the minimum age. Greece has identified digital tools such as Gov.gr Wallet and Kids Wallet as possible ways to support age checks. The precise implementation and how platforms will meet the requirements remain important questions ahead of the January deadline.

The government has linked the measure to concerns that social media use can interfere with children’s sleep, concentration and personal relationships. However, enforcing the age limit will depend on how platforms identify underage users and prevent them from creating or retaining accounts.

Age verification also raises questions about privacy. Systems that require identity documents or other personal information could expose users to additional data risks. The European Commission has been developing an age-verification system designed to confirm whether someone meets an age threshold without sharing their identity with the platform.

Greece Joins a Wider International Push

Australia became the first country to enforce a nationwide ban on social media for children under 16 in December 2025. Its law requires covered platforms to prevent underage access, with substantial financial penalties for non-compliance.

In Europe, the European Commission proposed the EU KIDS Act in September 2026. The proposal would prevent children under 13 from accessing social media accounts, allow limited, parent-supervised accounts for those aged 13 and 14, and set 15 as the minimum age for independently managed accounts. The proposal still needs approval through the EU legislative process.

These approaches differ in their age thresholds and enforcement mechanisms, reflecting an ongoing debate about how governments should balance children’s protection with access to digital communication and information.

Climate Disasters Disrupted Schooling for 171 Million Students in 2025, UNICEF Finds

Climate disasters disrupted schooling for 171 million students worldwide in 2025, highlighting the urgent need for climate-resilient schools and education systems.

Climate-related disasters disrupted schooling for at least 171 million students worldwide in 2025, affecting one in every 10 school-age children, according to a new UNICEF report that warns of growing threats to learning, educational equality and future economic prospects.

The report, Learning Interrupted: Global Snapshot of Climate-Related School Disruptions in 2025, released on September 10, analysed data from 106 countries and territories. It found that storms, floods, heatwaves, droughts and wildfires caused school closures, shortened teaching hours, reduced attendance and shifts to remote learning.

The findings underline how climate change is emerging as a threat to educational continuity, particularly in countries where schools lack the infrastructure and resources to withstand extreme weather.

Storms and floods interrupt learning

Storms were the leading cause of climate-related school disruptions in 2025, affecting 109 million students globally. Floods affected at least 70 million, while heatwaves disrupted schooling for approximately 50 million children. These figures overlap and should not be added together as separate groups.

In Pakistan, severe monsoon flooding in August delayed the return to school for more than 28 million students. In Egypt, a powerful Khamsin wind-and-dust storm prompted a nationwide suspension of classes for one day, affecting more than 28 million students.

The problem extends beyond individual disasters. Forty countries experienced multiple rounds of climate-related school disruptions during 2025, exposing students to repeated interruptions throughout the academic year.

Floods can damage classrooms, sanitation facilities and learning materials, while extreme heat can make classrooms unsafe and undermine students’ ability to concentrate. Even after schools reopen, damaged infrastructure, disrupted transport and household financial pressures can prevent children from returning to regular attendance.

A growing threat to educational equality

Three-quarters of the students affected in 2025 lived in low- and lower-middle-income countries, where education systems often have fewer resources to prepare for disasters and restore teaching afterwards, UNICEF found.

The World Bank’s 2024 report, Choosing Our Future: Education for Climate Action, offers further evidence of the long-term challenge. It estimated that 400 million students globally experienced school closures due to extreme weather between 2022 and 2024. In affected schools in low-income countries, students lost approximately 45 instructional days between January 2022 and June 2024, compared with around six days in high-income countries.

These interruptions can compound existing educational disadvantages. Students from wealthier households may have access to private tutoring, digital devices and alternative learning arrangements. Children from poorer households may lack internet connectivity, electricity or suitable spaces to study during closures.

South Asia’s exposure highlights the challenge

UNICEF’s previous assessment, covering 2024, recorded at least 242 million students experiencing climate-related school disruptions across 85 countries and territories. South Asia was the most affected region, with 128 million students impacted. Heatwaves affected an estimated 171 million students worldwide that year.

India was among the countries affected by heat-related educational disruptions. In April 2024, extreme heat contributed to school interruptions across Bangladesh, Cambodia, India, the Philippines and Thailand, affecting at least 118 million children collectively. The figure represents the five-country group, not India alone.

The 2024 and 2025 totals should not be interpreted as a direct year-on-year decline. The reports covered different sets of countries and climate events, and the number of recorded disruptions depends on the incidents identified in each assessment.

Climate-resilient schools become a priority

UNICEF estimates that disruptions experienced in 2025 could cost affected students at least US$200 billion in lifetime earnings through lost learning and widening educational inequalities. This is a projection of potential future losses, rather than income already lost.

The World Bank has argued that relatively modest investments can help schools adapt. Its 2024 analysis estimated that a one-time investment of US$18.51 per child could help mitigate learning losses through measures such as improving classroom temperatures, strengthening school infrastructure and training teachers.

UNICEF is calling for climate resilience to be incorporated into education planning, alongside investment in stronger school buildings, emergency preparedness and systems that allow teaching to continue during disasters.

As extreme weather increasingly interrupts academic calendars, education systems must prepare not only to enrol children but also to protect their ability to learn. Climate-resilient infrastructure, early-warning systems and plans for educational continuity will be essential to ensuring that disasters do not deepen existing inequalities in access to education.

Global Job Market Faces a Growing Inclusion Gap as AI and Digitalisation Reshape Work

Global employment faces a growing inclusion gap as AI and digitalisation reshape the labour market. UN and ILO reports highlight persistent informal employment, youth exclusion and unequal access to the skills needed for emerging jobs.

The global economy is undergoing a profound employment transition, driven by artificial intelligence (AI), digitalisation, demographic changes and the shift towards greener industries. Yet, while these forces are expected to create new career opportunities, access to employment and the benefits of technological progress remain deeply unequal, according to the United Nations’ World Social Report 2026.

Released on October 15, the report, published by the UN Department of Economic and Social Affairs (UN DESA), warns that billions of people remain excluded from the jobs, skills, infrastructure and social protections required to participate in economic transformation. Its findings highlight a central challenge for policymakers: creating employment opportunities is not enough unless people can access them and secure decent working conditions.

The scale of the problem is evident in the report’s latest figures. In 2025, 58 per cent of workers worldwide were informally employed, while 27 per cent of young women aged 15–24 were neither employed nor participating in education or training. An estimated 2.2 billion people also lacked internet access, limiting their ability to benefit from digital services, online learning and emerging employment opportunities.

More Jobs, but Unequal Opportunities

The challenge extends beyond unemployment to the quality and security of work. The International Labour Organization’s Employment and Social Trends 2026 report estimated that global unemployment would remain at 4.9 per cent in 2026, equivalent to approximately 186 million people. However, nearly 300 million workers continued to live in extreme working poverty, surviving on less than US$3 a day. The report also projected that 2.1 billion workers would be in informal employment in 2026, often without adequate social protection or employment security.

Young people face particular difficulties entering the labour market. According to the ILO, youth unemployment reached 12.4 per cent in 2025, while approximately 260 million young people were not in employment, education or training. For many, the transition from education to work remains uncertain, particularly where economies fail to generate enough productive jobs.

These challenges coincide with substantial changes in the kinds of jobs employers expect to need. The World Economic Forum’s Future of Jobs Report 2025, based on projections from more than 1,000 employers, estimates that technological, economic, demographic and green-transition trends could create 170 million jobs globally by 2030 while displacing 92 million. This would produce a net gain of 78 million jobs. However, the report warns that the transition will require extensive workforce adaptation. Nearly 40 per cent of workers’ existing skills are expected to change by 2030, and 63 per cent of surveyed employers identified skills gaps as a major barrier to business transformation.

The projections suggest that the central employment challenge is not simply whether jobs will disappear, but whether workers can move into emerging roles. Demand is expected to grow in areas such as AI, data analysis and cybersecurity, alongside essential occupations in healthcare, education and agriculture. Workers whose skills do not match changing requirements risk being excluded even as new vacancies emerge.

Digital Access and Skills Will Shape the Transition

Access to technology is another dividing line. The World Bank’s Digital Progress and Trends Report 2025 identifies disparities in connectivity, computing infrastructure, relevant data and digital skills as barriers to wider participation in the AI economy. While AI adoption is expanding, high-income countries continue to dominate important areas of AI innovation and computing capacity.

For people without reliable internet access, affordable devices or opportunities to acquire digital skills, the shift towards online recruitment, digital services and AI-assisted work can deepen existing disadvantages. Connectivity alone, however, is insufficient: workers also need relevant training, accessible education and opportunities to apply their skills in productive employment.

The UN report argues that governments must invest in quality education, lifelong learning, digital and AI capabilities, affordable connectivity and stronger social protection. Labour-market policies must also support decent working conditions, equal opportunities and training that helps workers move between occupations.

For developing economies with large young populations, the stakes are particularly high. A growing workforce can support economic growth only when enough productive jobs are available and workers can acquire the capabilities those jobs demand. Without such opportunities, demographic potential can translate into prolonged unemployment, insecure work and widening inequality.
