11 million trees planted in November are almost all dead in Turkey

It was a fine record for a “greener Turkey” emanating from a government often criticized by environmentalists. A record that has fizzled.

On 11 November 2019, decreed a day of “national reforestation” by Turkish President Recep Tayyip Erdogan, 11 million fir trees were planted across the country, recalls the daily Hürriyet. A project of public initiative, to which individuals were called to join by contributing financially or by planting themselves a tree in their garden.

according to the Agriculture and Forestry Union, victims of the lack of water. “They did not want to listen to the warnings of the experts, who explained in particular that the season and the rain forecasts were not favorable for this project, but their only concern was to beat the record”,

I do not know the veracity of these facts ... but the photo of illustration, showing an adult forest (or almost) of international mail seems to me untrue ...

Is it because an initiative has failed that we must condemn them all?

If a car crashes on leaving the dealership because the driver can't drive, we stop manufacturing all the cars in the world? : Cheesy:

The bullshit is not to plant trees but to do it anyhow and anytime to get lather and get into Guinness ...

The town hall wanted to cut it after the storm of the century in 1999.
Fortunately, the pruners' insurance was too expensive. As soon as he falls into town in the river 20m away

In Portugal, they decided to replant something other than fuel monocultures. Common yew and native species (késako) such as cork oak ...

Good initiative. For once it is realistic and not too expensive.
But it must be seen that all the vegetation "works" at constant CO2. It only stores additional CO2 when it grows, otherwise it is recycled. We only gain in retention of additional CO2 on the vegetation delta from one year to the next, which can nevertheless not be negligible.

The carbon cycle does not stop at vegetation
The great carbon cycle, in which organic soil carbon (COS) enters
take into account the carbon cycle in the soil, but also in the vegetation, the ocean and
the atmosphere (Figure 1). COS content is estimated to be around 1 PgC between 500
and 1 meter deep. This represents more carbon than what is currently
contained in the atmosphere (about 800 PgC) and in terrestrial vegetation (500
PgC) combined (FAO and ITPS, 2015) (See section 3.1 for more information on
COS reserves). This phenomenal amount of COS is not static, but evolves
continuously through cycles between the different carbon reserves, under
various molecular forms (Kane, 2015).

Carbon dioxide (CO2
) and methane (CH4
) are the main atmospheric gases
containing carbon. In the soil, autotrophic organisms (mainly
plants), as well as photo- and chemotrophic microbes synthesize CO2
from the atmosphere and thus produce organic material. Equipment
dead organic (mainly in the form of plant residues or exudates) is
incorporated into the soil through soil fauna. Through the transformation of
organic material by heterotrophic microorganisms, additional carbon
is integrated into the ground. This process of transformation of organic material results in
a complex biogeochemical mixture of compounds from plant litter and
products of microbial decomposition at different degrees of decomposition (Von
Lützow et al., 2006; Paul, 2014). These products can be combined with minerals from
soil or blocked within aggregates, thus allowing COS to persist in the soil
for tens, hundreds, even thousands of years (Schmidt et al., 2011).
When soil organic matter (MOS) is broken down (or mineralized) by
microorganisms, CO2
is emitted back into the atmosphere. Root exudates
such as oxalic acid, which releases organic compounds from combinations
protective minerals can also cause carbon losses (Keiluweit et al.,
2015). Finally, part of the soil carbon is also exported to rivers and
oceans in the form of dissolved organic carbon (DOC) or in erosion material.
http://www.fao.org/3/b-i6937f.pdf
The largest soil carbon stocks are in permafrost and the melting due to global warming is already exceeding storage expectations with the idyllic planting of trees.
It's already lost.

But also
Not every forest is a "carbon sink". The ability of trees to sequester CO2 depends on many conditions. Climate, in particular. "When the rains are lacking for a long time, the function of the forest as a carbon sink is seriously disturbed," explains INRA. So much so that some forests, especially those in northern Europe and tropical forests, can temporarily become net emitters of CO2 during a prolonged drought. ”

Other factors can affect the forest. Insect attacks can considerably reduce its absorption capacity, and fires "can send into the atmosphere in a few hours all the CO2 that a forest has patiently accumulated over the decades", continues INRA

Yes, and it is above all a political attack on the part of an Erdogan opponent, therefore not something very reliable by nature.

Below is another version, according to which 95% are still alive:
http://www.hurriyet.com.tr/gundem/10-mi ... uage=tr_TR

Note that the planting was carried out in 81 provinces.

And even if 90% of the trees were dead, it would still make 1 million living trees, it's still good to take.
