Our results demonstrated that climate anomalies substantially affect crop yield variability in Eastern and Southern Africa. On average, El Niño shocks are likely to cause a reduction in crop yield in Southern Africa. La Niña episodes, on the other hand, are associated with increased wheat and maize production.
What are the impacts of El Nino in Africa?
In Africa, El Niño conditions are associated with increased rainfall in East Africa and decreased rainfall in southern Africa, West Africa, and parts of the Sahel.
What are some impacts of El Nino?
Severe drought and associated food insecurity, flooding, rains, and temperature rises due to El Niño are causing a wide range of health problems, including disease outbreaks, malnutrition, heat stress and respiratory diseases.
What are the impact of El Nino in the economy?
El Nino causes drought
Inflation in Africa’s most advanced economy moderated to 4.6% in August from 5% in July, but the central bank has warned that drought remains a concern because of its impact on food prices.
How El Nino affects the environment?
Ecosystems and human communities can be positively or negatively affected. For example, in the Southern United States, during the fall through spring, El Niño usually causes increased rainfall and sometimes destructive flooding. … Changes in ocean temperatures and currents that happen during El Niño impact marine life.
Is El Nino good or bad?
And for people across the Gulf States and the Eastern Seaboard, El Niño does one really good thing in the Atlantic Ocean in the summer and fall. It generates powerful high-altitude winds that cut the tops off of tropical storms before they can grow into hurricanes.
What are the impacts of El Nino and La Nina?
El Niño and La Niña affect not only ocean temperatures, but also how much it rains on land. Depending on which cycle occurs (and when), this can mean either droughts or flooding. Typically, El Niño and its warm waters are associated with drought, while La Niña is linked to increased flooding.
What are causes and effects of El Nino?
El Nino is essentially caused by the interaction between the surface layers of the tropical Pacific Ocean and the atmosphere over it. The water is warmer due to the trade winds reversing direction or becoming less intense.
What is a positive effect of El Nino?
On the other hand, in the United States, El Niño typically brings wet weather to California (benefiting lime, almond, and avocado crops, among others), warmer winters in the Northeast, increased rainfall in the South, diminished tornado activity in the Midwest, and a decrease in the number of hurricanes that hit the …
What effects does El Nino have on weather and climate?
El Niño causes the Pacific jet stream to move south and spread further east. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North. El Niño also has a strong effect on marine life off the Pacific coast.
