El Niño and Its Effects on the World Economy

El Niño and Its Effects on the World Economy Abstract El Niño is a major climate phenomenon that originates in the tropical Pacific Ocean but produces economic consequences across the world. Changes in temperature and rainfall associated with El Niño can affect agriculture , fisheries, energy production, transportation, international trade, inflation, and economic growth. Countries that depend heavily on agriculture and natural resources are particularly vulnerable. Reduced crop production can increase food prices , while disruptions to energy and supply chains can raise production costs.

This article examines the major effects of El Niño on the world economy and discusses measures that governments and businesses can adopt to reduce economic risks. Keywords: El Niño, World...
