On this World Environment Day, we are reminded that the planet is speaking to us with growing urgency through shifting climates, stressed ecosystems, and rising risks calling for our immediate and sustained response. Science confirms that global temperatures have already approached 1.5°C above pre-industrial levels, with emissions continuing at record highs of nearly 58 billion tonnes in 2024. This is not a distant threat, it is today’s reality, unfolding across communities and economies worldwide.

In Sri Lanka, the experience of Cyclone Ditwah in 2025 laid bare the true cost of delayed action. Bringing intense rainfall of up to 500 mm, widespread flooding, and landslides across 22 districts, the cyclone exposed over 2.2 million people and directly affected more than one million lives across the country.  The human and economic toll has been profound. Lives were tragically lost, communities displaced, and critical infrastructure, livelihoods, and ecosystems severely disrupted. The Post-Disaster Needs Assessment estimates total damages and losses exceeding US$3.4 billion, underscoring the scale of recovery required and the urgency of strengthening resilience systems nationwide.

Beyond the immediate impacts, Cyclone Ditwah confirms a deeper, systemic challenge. Evidence suggests that climate change has intensified extreme events affecting Sri Lanka, increasing both the frequency and severity of such hazards.  This convergence of climate risk, environmental degradation, and socio-economic vulnerability has amplified the disaster’s effects, transforming a natural hazard into a multidimensional crisis affecting people, economies, and ecosystems simultaneously. And the horizon offers no respite: the World Meteorological Organization has just warned that El Niño is now developing, with an 80% chance of onset between June and August 2026 and a near or above 90% likelihood of persisting through November. For a country still recovering from Ditwah, this signal demands urgent attention. El Niño conditions typically bring above-average temperatures and disrupted rainfall patterns across South Asia, with direct consequences for agriculture, water security, energy, and livelihoods.

This World Environment Day, we renew our commitment to act—urgently and collectively. The cost of inaction is exponential. Globally, climate-related economic losses could reach up to 15% of global GDP by 2050 if warming continues unchecked. 

UNDP Sri Lanka remains firmly committed to supporting the Government and people of Sri Lanka in this journey. As a trusted technical partner, UNDP advances integrated solutions across climate action, natural resource management, and sustainable energy & waste, aligned with Sri Lanka’s commitments under the three Rio Conventions and national priorities including the NDCs 3.0, National Biodiversity Targets, and Land Degradation Neutrality targets.

Our work focuses on strengthening resilience at all levels: supporting national policy frameworks while delivering transformative, community-based solutions. Across the country, vulnerable communities are being empowered through climate-smart agriculture, improved water resource management, and access to climate information systems, contributing to enhanced adaptive capacity and more resilient livelihoods. Equally, UNDP is promoting nature-based solutions that recognize ecosystems as critical infrastructure for resilience, demonstrating that environmental protection and economic development can be mutually reinforcing. At the systems level, UNDP is supporting Sri Lanka to unlock innovative climate and nature financing, working to bridge the financing gap and channel investments towards resilient, low-carbon, and nature-positive development pathways. 

Cyclone Ditwah has reinforced the critical importance of this integrated approach. The scale and interconnected nature of the impacts, from damaged infrastructure and disrupted livelihoods to degraded ecosystems, demonstrate that resilience must be built across systems, sectors, and at scale. Climate action, nature conservation, disaster risk reduction and just energy transition are not parallel agendas, but deeply interconnected pillars of sustainable development.

Looking ahead, Sri Lanka has a unique opportunity to transform adversity into resilience. By embedding climate adaptation, ecosystem restoration, and inclusive development into recovery efforts and economic plans, the country can not only rebuild what was lost but also reduce future risks and strengthen long-term resilience. 
But this transition cannot rest with a single institution. The resources required to implement the NDCs alone far exceed available sovereign financing. What is needed is a whole-of-society response—communities, the private sector, researchers, financial institutions, and development partners, moving together at the scale this moment demands. 

Today, UNDP reaffirms its commitment to supporting Sri Lanka on this journey — working alongside communities on the frontlines of climate change, restoring ecosystems that serve as the country's first line of defence,  as a steadfast partner to the Government to translate NDC commitments into concrete and time-bound action, and mobilising climate and nature financing to close the gap between ambition and implementation.
