Everyone is talking about climate change, but the climate targets are still not being met.
The cultivation of cocoa is significantly affected.
Update from September 22, 2020
: There is no doubt that
sooner or later
climate change will
pose a threat to cocoa plants, which
grow
especially in countries such as the
Ivory Coast
or
Ghana
(see explanation below).
However, many scientists doubt that we will have to do without chocolate * entirely from 2050 onwards.
For example, Ingrid Parker, professor of ecology and evolutionary biology at the University of California, Santa Cruz, told Snopes magazine that the plant could
easily be grown in other countries
: “Cocoa has already grown in other countries like Australia.
The plant is not even originally from Africa, as it actually comes from the New World. "
The Institute for Innovative Genome Research at the University of California, Berkeley also issued a press release on the subject some time ago.
In it, the scientists confirm that the areas that are suitable for growing cocoa
will be less due to climate change in the next few years
.
As a result, cocoa plants are very likely not to die out completely.
Will there be no more chocolate soon?
News from November 11, 2018
: Perhaps another shock message is needed to rethink the climate: The cocoa plant is dying out and to blame are rising temperatures in the growing areas.
The impact is so massive that US scientists have
already calculated
the
final end for 2050
.
By then, the plant should have disappeared from the already rare growing areas.
Sensitive plant cannot withstand rise in temperature
The cocoa plant is very demanding and reacts sensitively to changing climatic conditions.
The changes make the
previous cultivation areas unusable
, according to the researchers' gloomy scenario.
In order to achieve constant values, the farmers would have to switch to
higher-lying cultivation
areas.
However, these cannot be used due to the
species protection of the animals living there
.

Only two main export countries
Suitable cultivation areas are so rare because the demanding plant can only
grow
in a
narrow strip of the rainforest around the equator
.
More than half of the world's chocolate quantities therefore come from two countries:
Ghana and the Ivory Coast
.
If climate change is not stopped and the average annual temperature rises worldwide by two degrees or even more, it will be
too hot
in the large flat cultivation areas of West Africa
for the heat-sensitive cocoa plants
.
A way out of genetic engineering?
One solution would be
genetically modified cocoa plants
that can cope better with higher temperatures, less water and pests.
Optimized cereal plants are the model here.
Corresponding research is already available at the University of Berkeley.
However, these processes are viewed with suspicion by consumers.
