What are the economic impacts of El Nino in Africa?

El Nino Impacts (2015/16 Season)

accompanied by high temperatures leading to: – Reduced crop yields – Cattle deaths – Low dam levels due to less inflows – Sectors affected include food security, livelihoods, agriculture, livestock, nutrition, health and water, sanitation and hygiene (WASH).

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 3 effects 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.
