Forest fires

by Jhony Pico

Introduction

For forest fires we refer to fires (whether of natural or anthropic origin) that occur in terrestrial ecosystems, and which are propagated by vegetation, of whatever type (forests, savannas, shrublands, grasslands, wetlands, peatlands, etc.). ). Most people associate forest fires with catastrophic events, fires are part of the same nature and have shaped the diversity of our ecosystems. (Juli G. 2012).

Forest fires are one of the main agents of disturbance of the ecosystems of the planet, where millions of hectares are affected every year. The high pressure of human activities and global warming are increasing the frequency, intensity and size of these fires, with important consequences for both natural communities and society as a whole.

WHAT ARE THE CONSEQUENCES OF FOREST FIRES

Fires also affect soil quality, increasing soil pH and erosion. There is also a destruction of the landscape, the same that affects mainly humans. The effect on the waters alters the ecosystems of this environment, as they become turbid with the ashes disturbing the development of aquatic plants, the breathing of animals. Forest fires affect all areas of nature. Over the vegetation, a fire can have serious negative effects, such as the destruction of all types of plants and trees, and many of the surviving trees will be weakened, being more vulnerable to various pests and diseases.

In addition when the fire affects human populations, the consequences are dramatic. People can lose their lives, besides their houses, their crops and many times their animals.

On animal life, the consequences of forest fires are truly catastrophic. In addition to the deaths of many animals, their habitats are completely destroyed and food shortages occur, and water, soil and air pollution

Of course, forest fires also cause effects on the atmosphere due to the high emissions of gases such as carbon dioxide, methane and carbon monoxide, which contribute to increasing the greenhouse effect. The soil after the fire is almost sterile due to the mineralization of the organic matter and limits the recolonization of the native plants. In addition, torrential fires and rains increase erosion by reducing the chances of recovery. Often, the economic costs of a forest fire are virtually incalculable, since the nature and life of animals is priceless. Worst of all, is that they are usually fires intended by humans.

If conditions are optimal, a forest fire can start almost anywhere, anytime. Most fire hazards occur when the weather is dry and hot. Every summer many countries suffer from large forest fires that have a far greater ecological impact than burned trees. Among the most negative consequences are the destruction of biodiversity, the increase of desertification or the pollution of water and the atmosphere.

FOREST FIRES
Forest fires in forests, jungles, and areas with vegetation are consumed uncontrollably by fire, which can easily spread over large areas. The same that affects all areas of nature On the vegetation, a fire can have serious negative effects, such as the destruction of all types of plants and trees, in addition many of the trees that survive will be weakened, being more vulnerable to various pests And diseases.
Forest fires are recorded in any part of the world, being considered when they occur naturally that are part of the balance mechanism that exists in the environment, however, extra natural causes are higher and are giving rise to serious concerns within each One of the countries that confront these problems.

Fire is a natural regulator of some ecosystems, so the occurrence of forest fires in many parts of the world responds to climatic behavior and to the natural susceptibility or adaptation of vegetation to ignition and flammability, especially during periods of dryness. Thunderstorms and volcanic eruptions are the most frequent natural causes by which fire is present.
Fire has been a constant agent of changes in the landscape, in the maintenance and evolution of Ecosystems, and an essential part of human life systems since ancient times. Its ecological role as process regulator has been a fundamental part of the evolutionary history of the earth, particularly when its origin is a consequence of natural processes.

 

Burned areas take several years after a forest fire, plant species and fauna acquire the characteristics of a young forest. The number of years for the regeneration of the forest depends on the growth rate of the plant species that make it up.
On animal life, the consequences of forest fires are truly catastrophic. In addition to the deaths of many animals, their habitats are completely destroyed and food shortages occur, as well as water, soil and air pollution. Fires also affect soil quality, increasing PH and erosion. There is also a destruction of the landscape, which mainly affects humans.

Forest fires occur throughout the world and in the case of countries like the United States occur in most of the 50 US states, although it is more common in the west of the country. Other countries in the Mediterranean area such as Portugal, Greece, southern France or Italy also suffer especially. Despite this first-rate problem, there is no community forestry policy. These countries are joined by Indonesia, Austria, Germany, Malaysia, Singapore.
In Latin America, Brazil is the country with the highest number of fires. In other countries, such as Chile, fires also occur due to the environmental conditions present in this country, such as the lack of rainfall, higher air temperature and South wind flows, conditions that occur from the spring of one year to the fall of the next, favor the ignition of combustible vegetation due to a source of heat provided by the human being (teleSUR, 2016).

This phenomenon can be both natural and not because forest fires in forests or areas of vegetation are quickly consumed by fire. Spring came in the northern hemisphere, the most dangerous time for forests, especially those between the tropic of cancer and The equator (Mexico, Central America, Central Africa, India and Southeast Asia), as well as Russia. For these dates, there are places that have been over 6 months without rain, the forests are full of dry leaves and the heat of spring is increasing. The fires are the order of the day.

Forest fires are present in almost all the world from America such as the United States, this phenomenon affects 50 of its states, also this type of natural phenomenon occur in other Mediterranean countries such as Portugal, Greece, southern France or Italy also suffer especially.

Forest fires are a natural phenomenon to be provoked by the same nature, this natural phenomenon is present all over the world, in some countries of the world in summer-autumn times are common this type of natural phenomenon due to climate change and shortages Water.
