The hidden economic bill of Nepal’s monsoon disasters
[...]
Only five of the 32 major weather-related disasters recorded between 2015 and 2025 include any estimate of economic damage, meaning around 84 percent have no reported monetary loss figure. Without reliable loss estimates, it is difficult to demonstrate the true cost of disasters or justify greater investment in prevention. Therefore, improving disaster loss data should be a priority for the National Disaster Risk Reduction and Management Authority (NDRRMA) and other relevant agencies to support more informed investment decisions.

The September 2024 floods illustrate how quickly disaster losses can accumulate. A preliminary government loss and damage assessment found the floods damaged 65,380 hectares of agricultural land, killed nearly 27,000 livestock, and contributed to an estimated Rs46.68 billion in losses across infrastructure, agriculture and other sectors. This reflects a broader national pattern. Nepal’s average annual disaster loss is estimated at Rs2.78 billion, or about 0.08 percent of GDP, but in extreme years losses can reach 2.08 percent of GDP, around 25 times higher than the annual average. This wide variation suggests that a small number of catastrophic disasters account for a disproportionate share of Nepal’s economic losses.

The visible damage caused by disasters is often repaired. Roads are rebuilt, bridges restored and schools reopened, but the less visible losses are far harder to recover from. Families lose income, children miss school and debts grow. The evidence shows that investing before disasters occur is more effective than paying for recovery afterwards. According to the UNDRR, every dollar spent on disaster risk reduction can save four to seven dollars in future response and recovery costs. With Nepali households already losing around Rs83 billion to disasters each year, risk reduction should be placed at the centre of disaster management alongside emergency response. Weather disasters are bound to happen. Their financial burden is not.
