United Nations defines Natural disaster as a sudden, catastrophic event caused by the natural environment, such as earthquakes, floods, hurricanes, landslides, volcanic eruptions, and tsunamis.
Causes of Natural Disasters –
- Tectonic plate movement causes natural disasters through plate collision,magma release and oceanic plate displacement.
- Climate and weather change causes natural disasters through rising temperatures,intensified precipitation,sea level rise and melting glaciers.
- Human induced causes of disasters include deforestation,pollution,over extraction,urbanization and industrial accidents.
- Biological causes of natural disasters include disease outbreaks,insect infestations,animal migration,plant pathogens and microbial contamination.
Effects of Natural Disasters –
- Natural disasters have devastating humanitarian effects, including loss of life, injury, displacement, family separation, psychological trauma, increased poverty and long term suffering.
- Severe economic impacts including infrastructure damage, property loss, revenue decline, business disruption, increased debt, inflation, and economic stagnation.
- Devastate environment by causing habitat destruction, biodiversity loss, soil erosion, water pollution, air contamination, deforestation, and climate change .
- Profound social impacts including community displacement, social isolation, cultural heritage loss, educational disruption, healthcare setbacks, increased crime and psychological trauma.
Natural disasters have devastating impacts on humans, environment, and economy. Preparedness, resilience, and cooperation are crucial to mitigate effects, save lives, and rebuild communities for a safer future.

Indian cities struggle with monsoon preparedness due to a combination of factors. *Outdated Drainage Systems* are a major issue, with many cities’ drainage systems designed decades ago, unable to handle the increasing intensity of rainfall . For instance, Delhi’s drainage system, built nearly 50 years ago, struggles with even 50 mm of rain.
*Climate Change Impact* is another significant factor, with intense, localized rainfall becoming more common . This is evident in the changing monsoon patterns, where 55% of India’s tehsils saw an increase in southwest monsoon rainfall between June and September in the past decade .
*Poor Urban Planning* also plays a role, with cities not considering natural water flow, leading to water accumulation and flooding . Historical areas, like Minto underpass in Delhi, are particularly vulnerable due to their low-lying location.
Additionally, *Vulnerable Populations* are disproportionately affected, with the poor and lower-middle-class bearing the brunt of these failures . Informal settlements, often ignored in city planning, experience significant disruptions and health risks due to ineffective handling of stormwater mixed with sewage.
Lastly, *Historical Neglect* of natural water channels has contributed to the problem, with many channels covered or polluted over time . To improve monsoon preparedness, cities can learn from historical water management practices, integrate natural hydrology into urban planning, regulate urban infrastructure, prioritize vulnerable populations, and regularly desilt drains .
