10 billion trees disappear annually.

10 billion trees disappear annually.

El Telégrafo newspaper, Ecuador, Wednesday, April 19, 2017.

Globally, about 10 billion trees are lost annually by felling, fire and farming practices at that rate of deforestation, trees will be extinct in 300 years. Bolivia has 5,000 trees per person, in Ecuador there are 468 trees per inhabitant and in Israel 2 trees per inhabitant. The great difference is due to natural factors, climate, topography, soil characteristics, agricultural development, industrial, urban and the impact of human activity,when the world population increases, more is the impact on forests. The greatest extent of forests is in the tropics, with 43% of all trees on the planet, the greatest involvement in forests is manifested in Europe.

In Ecuador there are 7.65 billion trees, which are distributed in 12.7 million hectares of forest. This represents 468 trees per inhabitant. The provinces of the Amazon region, according to the Ministry of the Environment (MAE), have the most natural areas and forests: they cover 74% of the total area; While 15% corresponds to the territories of Guayas, Manabí and Esmeraldas. In Ecuador, between 2008 and 2014, 47,000 hectares of forest and mangroves were lost, because these areas were dedicated to agricultural purposes. “We have managed to reduce deforestation by 49%, if we take as reference the last two decades in which 92,742 hectares were lost per year,” said the MAE.

Globally, about 10 billion trees are lost annually by felling, fire and farming practices. “At this rate of deforestation, the trees will be extinct in 300 years,” according to research published in the journal Nature. International research reports that there are currently 3 trillion trees on the planet. Satellite images showed that there were only 400,000 trees previously; Nevertheless when conducting studies in the field it was verified that the reality was another.

In 2013, studies based on direct counts confirmed that there are only about 400,000 million trees in the Amazon. According to the research, there is a huge inequality: Bolivia have 5,000 trees per person and Israel, two per inhabitant. Much of the contrast is due to natural factors: climate, topography or soil characteristics, but also the impact of human activity. for more human population increases, more the population of trees decreases. According to the report, the largest expanse of forests is in the tropics, with 43% of all trees on the planet. The forests of the north represent 24% of the total and 22% are in temperate zones.

The greatest affectation of trees is in Europe, where before the civilization existed a great forest that gradually became extinct. “Human pressure due to agricultural, industrial and urban development made this region one of the most deforested in the world,” says Nature.

The net loss, offset by the emergence of new trees and reforestation, is 10,000 million. “The number of trees on the planet has been reduced by 46%, almost half of what there was.” The MAE since 2013 promotes the massive planting of plants in different places. In 2015, through the ‘Siembratón’ program, 765,000 shrubs of native species were planted in 2,300 ha. In addition, 765 hectares were covered to care for the coastal marine ecosystem mangrove.

The Importance of Trees

The set of tropical, temperate and boreal forests is the habitat of animals and differents organisms, ie it is a reservoir of terrestrial biological diversity. “They release water vapor that cools the air and moistens it; And fix atmospheric carbon dioxide (CO2) and transform it into oxygen, “explains Carlos Torres, environmental engineer.

The expert details that they mitigate the effects of the climatic change, since, through the evaporation, they return water to the atmosphere. Trees also intercept rainwater and allow it to seep into aquifers and prevent flooding. They are small ecosystems where animals and insects live that interact with each other. The Food and Agriculture Organization of the United Nations (FAO) stresses that the loss of forest diversity makes it impossible to obtain medicines, food, raw materials and employment, ie welfare. “Forests account for more than 10% of GDP in many of the poorest countries. It is estimated that the forestry sector provides formal employment to 10 million people and informal employment to 50 million in developing countries. ”

Paulownia is the most profitable Chinese tree

Paulownia is the most profitable tree in the world, five years after being planted. The species measures from 25 to 30 meters, its wood is semi-precious and with multiple applications. All its parts are useful, its leaves produce oxygen for the planet and grow at sea level and in areas up to 2,850 meters high. Colombian investors and peasants find Paulownia an excellent ally in both financial and environmental terms: roots reach a depth of 9 meters, recover soils, are ideal for reforestation, combat erosion and generate nitrogen.

The firm Agropaucol advises the farmer and the investor on how to prepare the land and design the irrigation system. “To be productive we advise to plant at least one hectare. If the irrigation is done correctly and the required care is provided, the sowing of a ha can cost $ 7,000. After five years, the wood can be sold at $ 45,000. The plant, a year after being sown, produces biomass for agglomerates and paper pulp. Also, after a year and a half can be drawn stakes for fences; At two years the plant blooms and is very useful in the production of honey and royal jelly. After flowering, the tree becomes very attractive to the landscape, it can be ornamental.
