Top 20 rainiest countries in the world 2025

Precipitation is an important part of the lifecycle on Earth. It supports life in all forms and is crucial for the economic and agricultural development of countries worldwide. Despite the Industrial Revolution of the 18th century, agricultural activity remains an important aspect of economies across the world. Even global powers like the USA, Russia, and China are among the top producers of agricultural products in the world. While China is one of the leading producers of agricultural products, the USA is amongst the largest exporter of the same.

Maintaining an agricultural economy is nearly impossible without ample rainfall. It plays a significant role in economic growth, especially in countries where agriculture is a major sector. For instance, in Thailand, ample rainfall has been identified as a blessing for poor provinces, contributing to their economic growth. In places where farming is the main source of income, like in Africa, unpredictable changes in rainfall patterns can have a major effect on both food availability and economic development.

Rainfall can also affect the presence of clean water supply in a country. Sufficient rainfall plays a vital role in sustaining water resources and enhancing sanitation. It aids in refilling groundwater reserves that are necessary for both drinking water and irrigation. This is especially significant in areas where the shortage of water is a major problem. Since rainwater is one of the primary sources of freshwater in many regions across the world, it is imperative to use this water supply wisely and store it for efficient consumption.
