El Niño
Storyboard Text
- What are the possible effects of El Niño on the environment?crop failure increase in disease due to lack of water for sanitation and hygiene blowing dust pollution of viable water sources decrease in near-shore coastal water quality.
- What happens in El Niño phenomenon?During an El Niño event, the surface waters in the central and eastern Pacific Ocean become significantly warmer than usual.
- How often does El Niño occur?El Niño typically lasts 9-12 months. It tends to develop during the spring (March-June), reach peak intensity during the late autumn or winter (November-February), and then weaken during the spring or early summer (March-June).El Niño can last more than a year, but it is rare for El Niño events to last longer than a year or so. The longest El Nino in the modern record lasted 18 months.
- How does El Niño affect agricultureThese adverse weather conditions have affected some coarse grain crops and the rice crops which have still to be harvested in the coming weeks. In some countries, the adverse weather conditions could lead to a delay in rice planting operations resulting in a switch to early maturing but lower yielding varieties.
- Preliminary indications point towards reduced rice acreage in some of the southern hemisphere countries. On May 2016, over 400,000 farmers and 550,000 hectares were directly affected by El Niño–induced drought. The Production losses in the agriculture sector due to El Niño rose to P7.96 billion in late April, according to the Department of Agriculture's Disaster Risk Reduction and Management Operations Center.
- What are the effects of El Niño on the environment?The result can be droughts and increased flooding, both causing severe water management challenges. The main feature of El Niño is a warm ocean current south along the coast of Ecuador, so named because it generally develops and peaks just after Christmas.
