Some considerations on El Niño and La Niña/natural phenomena.

Dear readers, in recent years there have been some natural phenomena that have considerably altered the climatic conditions in some regions, bringing with them some alterations in the ecosystems such as floods, severe droughts, hurricanes among others, particularly in my geographical area we have a humid tropical climate where rainfall has a certain regularity especially in the rainy season, however, there have been prolonged droughts that have affected agricultural production such as low production of fodder biomass for cattle feed.

The climatic conditions mentioned above have been attributed to two phenomena known as El Niño and La Niña. According to the literature consulted, these phenomena are due to the alteration of the waters of the Pacific Ocean; the first (El Niño) is caused by the irregular warming of the surface waters of the ocean and the second (La Niña) is due to the irregular cooling of the surface waters of the Pacific Ocean. In this sense, climate change specialists such as López (2013), point out that the warming of the Pacific Ocean waters is due to the weakening of tropical winds, which causes temperate waters to exceed cold waters, causing moisture to be released into the atmosphere and this moisture can be the cause of flooding in some arid areas.

As for the "La Niña" phenomenon, the same author mentions that in this situation the trade winds are more intense, which causes a greater amount of cold water to be dragged towards the eastern part of the Pacific Ocean, causing a drop in temperature and aridity on the American coast. Undoubtedly, these abrupt changes in climate can have adverse effects on public health due to the high relative humidity in some cases and also natural disasters, in addition to the low productivity in the agricultural sector as mentioned above.

The following are some of the effects of the El Niño phenomenon on productive activities, economy and public health as reported by Hijar and collaborators (2016):

Finally, I would like to point out that the name (the child) is due to the fact that the fishermen of the coast of Peru and Ecuador observed the change in temperature of the sea at times close to Christmas, therefore, they called it the child, alluding to the baby Jesus. These phenomena have been extensively studied due to the fact that such climatic changes significantly affect some sectors as mentioned in the article.

Greetings friend @amestyj. If these phenomena you mention affect mainly the agricultural sector, the rise in sea surface temperature due to the large amounts of water, health as these climate changes also raise diseases. Thank you for sharing your publication

Hello @sanadracarrascal, these phenomena are a sample of environmental imbalances, as you mention they impact on agricultural production, since they generate abrupt climate changes.

Greetings friend @amestyj, these two phenomena that you mention in your publication really affect food production, because when these phenomena appear the productivity of the field decreases significantly and that without mentioning the damage caused to health with the diseases it causes.

Hello dear @carlir the most affected sector of course is the agricultural sector, since, the production of plants depends on environmental factors and see the extremes of the same food production is affected.

See you later, have a great weekend.

Greetings friend, well to every action there is equal and opposite reaction i think this is third law of motion. Inspite of this, it is what you throw to your environment that your environment throw back at you. So therefore balancing of nature is a must called for in our imidiate world.
