On 26 August 2026, a rock-ice avalanche at Langtang Lirung (5,150 m asl) triggered a massive debris flood that travelled 200 km into India, causing over 1,300 deaths and widespread destruction in Nepal. The event released energy equivalent to a M5.5 earthquake and moved at average speeds of 188 km/hr. While geological structure was the primary control, the report finds that human-caused climate change significantly increased the likelihood and intensity of the anomalous warmth preceding the failure. Specifically, temperatures in July and August were approximately 1.5°C higher due to climate change, contributing to permafrost degradation, glacial thinning, and a shift in the rain-snow transition. The report concludes that the magnitude and speed of the event exceeded the limits of existing early warning systems and adaptation measures, necessitating a focus on loss and damage recovery.

The document details the struggles of Pasang Norchel Tamang, a herder in Rasuwa, Nepal, whose livelihood has been severely impacted since 2015 by decreasing precipitation and rising temperatures. These climate shifts have led to the depletion of water sources, reduced pasture productivity, and livestock health issues, including miscarriages and lower fertility rates. To maintain income, the herder has increased his livestock numbers, leading to higher debt and forcing his children to drop out of school. Additionally, hydropower projects have fragmented pastures and blocked access routes, further compounding the vulnerability of the ethnically marginalized Tamang community.

The document outlines a 'build back safer and greener' framework for Nepal, focusing on minimizing environmental damage during post-disaster recovery. It provides sector-specific guidance on settlements, building construction, waste management, energy, infrastructure, WASH, agriculture, and education. Key strategies include the use of soil bioengineering for landslide stabilization, integrated settlement planning, and the promotion of renewable energy to reduce pressure on forests. The guide emphasizes cross-cutting issues such as gender equality, social inclusion (GESI), and climate change adaptation to enhance long-term community resilience.
