Question

Collect information about the El Nino current that generates off the coast of Peru. Find out
the reason for the genesis of the El Nino current after every four years.​

Answer 1

Answer:

Disaster management policies are aimed at system resistance: maintaining or quickly returning to normal operations. This is the Peruvian approach to El Nio, but the cost of reconstruction rises with each event. Meanwhile, archaeological evidence shows that prehistoric farmers successfully managed El Nio events by developing resilient hybrid canal systems that used both river water and floodwater for agricultural production. Ancient farmers accepted the El Nio phenomenon as normal and accounted for floodwaters in their irrigation technology. As effective disaster management policy is developed in the context of the global climate crisis, this study calls for a conceptual shift.

In both ancient and modern Peru, the El Nio-Southern Oscillation has been regarded as a disruptor of environmental and socioeconomic equilibrium. Recent research in the Pampa de Mocan coastal desert plain challenges this view by demonstrating that prehistoric irrigation systems were designed to incorporate floods and convert them into productive waters. Archaeological studies in this area have revealed a 2,000-year history of floodwater farming embedded in conventional canal systems. Together with a pollen record recovered from a prehistoric well, these findings suggest that the Pampa de Mocan was a versatile landscape capable of utilising both El Nio floodwaters and river water.
