hello guys and good morning good afternoon or good evening again depending on what you are 00:00:00
doing right now today I am NOT going to do any question to focus in the two chapters that I 00:00:08
want to see today with all of you remember that if you have any doubt you can write me in the 00:00:17
forum you can you can also write me an email but the idea is the forum to 00:00:22
participate all with the same doubt if one of your doubt can solve any other 00:00:29
problem for one of your classmates will be so useful for all of us and even if 00:00:36
you are writing in the photo it could means that I can give you a point for 00:00:45
your participation then the other day we were talking about fishing and just the 00:00:50
difference between the three kind of fishing that we have that it was 00:00:56
divided into the small-scale traditional fishing fishing like commercial fishing 00:01:02
and the aquaculture and then to finish the chapter we mentioned where are the 00:01:09
main fishing grounds located. If you remain, I told you that fishing ground 00:01:17
means caladero. So today we are going to start with forestry. Another word for 00:01:24
forestry is silviculture, that is the cultivation of forests for exploitation 00:01:31
in a sustainable way, in a sustainable way nowadays because at the beginning 00:01:38
they didn't they didn't care about the situation so the idea is to protect the forest at the same 00:01:44
time that they are obtaining different products or or good because our forest is an important 00:01:53
element in the ecological balance then mainly we have two kind of product or good that we have 00:02:02
obtained in one hand we have the forest and timber production and in another hand we have the foreign 00:02:12
forest as a source of food then started with the first one the main activity related with 00:02:21
silviculture is to obtain wood basically this is the big majority of the activity related with 00:02:29
forests are phased to obtain wood for what for energy for construction to make 00:02:40
furniture to make paper and so on so it's there are a lot of different use 00:02:49
for the boot secondly unrelated with the other with the products that they are 00:02:58
going to obtain that we mentioned that they could be used for any Buddhist 00:03:09
consider the primary energy source for people because it makes up more than 9% 00:03:14
of the total supply of the world primary primary primary energy thing that there 00:03:23
are more than 2 billion people that is dependent on this kind of energy wood 00:03:33
fuel for cooking or for heating so nowadays not in Spain maybe but in 00:03:39
different parts of the world or in small regions or in small countries the wood 00:03:47
is still used as an energy source this maybe could sound a little bit strange 00:03:53
because you are you are listening all the time about the solar energy the wine 00:04:02
energy and so on but the wood is the most basic energy source and then 00:04:10
finally the wood for basic housing to construct for the construction of walls 00:04:18
of roads or roofs I don't know you have seen these American films where 00:04:25
sometimes the adolescent are moving away from home to build houses for poor people all of them are 00:04:31
made up of wood at the beginning the basic is made of wood then they will add different materials 00:04:40
to make a warm spaces and to protect them for any kind of climate situation but in the end 00:04:50
the most basic material is the wood and that's that's a big problem when there is a big fire 00:05:01
such as the one that they suffered in california a couple of years ago or in australia just a couple 00:05:12
of months ago because the basic housing is made of food and because of that is easy to burn 00:05:19
then secondly we can mention the forest as a source of food and it's and we can see differences 00:05:28
between the less economically developed countries and the developed countries because in a non 00:05:39
developed country the forest provide the food they need not all the food but part of the food 00:05:46
that they need while in the developed countries they it's totally linked with 00:05:54
produce or such as very mushroom truffles produce that normally you 00:06:03
cannot cultivate that is not related to the edible farming not all of them or 00:06:10
it's very expensive to maintain this kind of product and because of that 00:06:17
sometimes we can go to the forest and obtain that product on our own normally 00:06:23
the situation have to take care about the over exploitation of this kind of 00:06:29
produce especially for example with the mushroom because in autumn is quite 00:06:36
typical that a lot of people is moving to the countryside looking for mushrooms 00:06:41
and we can overexplode this kind of product and finally 00:06:47
mention the forest herb that are also used because there are many that have 00:06:57
has also become a high value then after mentioning mention the two main 00:07:05
in products related to self-culture, just to stop for a while, 00:07:15
in that we have to exploit the forest in a sustainable way 00:07:21
because approximately more than 100,000 km2 of forest are disappearing nowadays. 00:07:28
As a consequence, millions of animals lose their natural habitat. 00:07:39
The loss of forests means less carbon dioxide from the atmosphere is absorbed, 00:07:46
which strengthens the conditions associated with climate change. 00:07:53
For this reason, forests must be protected and exploited sustainably. 00:07:58
here I put you a map about the warm a forest all around well here in Spain as 00:08:05
you can see we have to we have two type of forests the one in the north that is 00:08:14
a temporary serious forest and the one in gray color that is not properly in 00:08:21
the legend in our case is the Mediterranean forest is not very 00:08:27
valuable because we only have the pine and any other any other tree that it 00:08:34
could be exploited is not a very important industry but also we have to 00:08:43
take that information into account and now what about the primary sector in 00:08:49
Spain as in every single country if you remember what we were talking about the 00:08:55
The pie chart related to the economic sectors all around the world, the most developed that you are, the most people working in the tertiary sector you have. 00:09:01
So, at the beginning, I'm talking from middle age and modern ages, the most important economic sector in the country was the primary sector. But of course, nowadays, this has changed a lot. 00:09:17
now today almost the fifth percent of the active population in Spain works in 00:09:36
the primary sector but as you compare with any other country that is another 00:09:42
developed country we mentioned that about the 50% of the population is 00:09:48
working in the primary sector but nowadays in Spain just the 5% of the 00:09:53
active population something that I want you to study by heart is the kind of 00:09:59
forms that we have because I don't know if you remember when you were in 00:10:08
Segunda de la Heso we were talking when the Christian started to be conquering 00:10:13
all the Jevi Jevi that belongs to Al-Andalus the way that they were 00:10:19
spread the spreading southward they made different resettlements at the beginning 00:10:25
in the duero river and in the tahoe river they made resettlements based on presura or 00:10:33
concejiles resettlement that it was based in free peasants or in small municipalities 00:10:40
but then from the tahoe southward they started to give big plot of land to the military orders 00:10:47
the novelty and the clergy because of that the type of farms in spain were quite different 00:10:57
in the north than in the south in the north normally we have agricultural small holy 00:11:06
In the middle we have medium-sized farms and in the south we have what we call 00:11:14
latifundia. Latifundia are large land holdings, big plot of land for extensive 00:11:26
and mechanized farming. This is quite typical in Castilla-La Mancha, 00:11:36
and andalusia these are the places where the military orders and novelty and the clergy 00:11:41
receive that big plot of land that still exists then the medium side side farms we can say that 00:11:48
about 30 hectares they tend to be family owners unoriented toward the production of high quality 00:11:58
products nowadays are increasing are increasing the number of medium-sized 00:12:08
farms because of regrouping what does it mean that there were a lot of small a 00:12:14
lot of small holdings farms that they work together to make a medium-sized 00:12:21
farms to to improve their productivity and their competition and finally we 00:12:28
have the agricultural small holding less than 10 tariffs more or less they have 00:12:37
experienced difficulties due to the market economy if you have a very small 00:12:45
plot of land you cannot cultivate a lot of production you cannot sustain obtain 00:12:51
a lot of product mainly we could find this kind of farm in the north of the 00:12:57
Iberian Peninsula and on the archipelago in Canary Island and in the Balearic 00:13:04
Island so keep in mind these three type of farms latifundia very big plot of 00:13:10
land medium-sized farms located more or less in the center of the Iberian 00:13:17
peninsula and agricultural small port okay guys i'm gonna leave right here and we will 00:13:25
continue with the rest of the primary sector in spain in the next recording have a nice day 00:13:35
