Hello everyone My name is Varya and the topic of

00:00:07

today’s lesson is resource sufficiency.

00:00:09

So let’s first turn to the

00:00:11

definition of what it is by

00:00:13

resource sufficiency, we mean the

00:00:15

relationship between the amount of natural

00:00:17

resources and the extent of their use,

00:00:20

while we can immediately

00:00:22

remember that resource sufficiency is

00:00:24

expressed in the number of years for

00:00:27

which resources will be enough or its reserves per

00:00:29

capita, it is still worth making a

00:00:33

very important note that the resources of

00:00:36

wealthy countries depend not only on the

00:00:38

reserves of these resources themselves, but also on

00:00:41

the amount of their use, hence we

00:00:45

can say that each country has

00:00:47

its own self-sufficiency. these

00:00:49

natural resources And it will

00:00:51

depend on the natural size of

00:00:53

the resource Yes, how many there are, not enough on

00:00:56

the range or complexity of these

00:00:58

resources, that is, they fulfill each

00:01:01

other or are they completely different

00:01:02

individual resources that cannot be

00:01:04

combined in any way in their production And of

00:01:07

course on the very needs of the country B

00:01:09

similar resources, for example, it is

00:01:12

completely irrelevant for a country to develop an

00:01:14

industry for which there is a resource.

00:01:16

Yes, and therefore we have to purchase these

00:01:18

resources from our neighbors, who have

00:01:19

much more. How can we calculate

00:01:23

mathematically this resource,

00:01:25

the security of countries? We have a very

00:01:27

simple formula, we are all exploring the

00:01:30

reserves that we need known must be

00:01:32

divided by their production volume Let's

00:01:35

try to solve the problem to make it

00:01:37

clearer, see Our task

00:01:39

Calculate Russia's supply of

00:01:41

iron ore if it is known that the

00:01:44

iron ore reserves in Russia are equal to 57

00:01:47

billion tons and at the same time

00:01:49

we produce 87 million tons annually,

00:01:52

remember our formula, we

00:01:55

divide the explored reserves

00:01:58

Let's divide by the volume of production and get in response the number of

00:02:01

years how long such a

00:02:03

resource will last, we get here 655

00:02:07

years, if we talk about forest

00:02:09

water or land resources, then it is

00:02:12

better to use the concept of the amount of

00:02:15

these resources per capita,

00:02:19

again we turn to the problem Calculate

00:02:22

Russia's supply of forest resources

00:02:24

if it is known that the forest area in Russia is

00:02:27

766 million hectares and the

00:02:30

population in 2023 was 143

00:02:34

million people, again we will

00:02:37

divide the reserves by the population size.

00:02:40

Our form is very similar. Let's divide them and

00:02:43

get 105.4 hectares per person. we

00:02:47

will be approximately standing out.

00:02:49

Of course, people constantly

00:02:52

use our natural resources, this one way or

00:02:54

another leads to their depletion. Therefore,

00:02:57

the number of years for which we have enough of

00:03:00

this resource, or the quantity per

00:03:03

capita, it will constantly

00:03:05

change with us because the total stock

00:03:08

will change from here we have the

00:03:11

concept of resource saving technologies

00:03:13

what is it this is a set of some

00:03:16

technological processes in which the

00:03:19

output of final products is realized with

00:03:23

minimal costs Those same

00:03:24

resources that is, a minimum of raw materials is required a

00:03:26

minimum of energy a minimum of, for example,

00:03:28

labor resources in the form of a person and so on

00:03:30

further That is, Our task is

00:03:33

to use natural resources wisely so that they do

00:03:35

not deplete ahead of time. Or we

00:03:37

could think in advance about some

00:03:39

alternative, what we will do if

00:03:41

our natural resource runs out. And of

00:03:43

course, try to save what

00:03:46

we have now, I have that Thank you all

00:03:48

for your attention and see you in the next

00:03:50

lesson

Description:

Ресурсообеспеченность – это соотношение между величиной природных ресурсов и размерами их использования. Выражается в количестве лет, на которое хватит ресурса, или его запасами на душу населения. 📌Содержание: 0:00 Ресурсообеспеченность 0:43 Самообеспечение ресурсами 1:21 Расчет ресурсообеспеченности стран 2:50 Истощение ресурсов 3:09 Ресурсосберегающая технология _______ 📝Цифровая энциклопедия Онлайн-школы: https://app.onlineschool-1.ru/10-klass/geografiya https://www.youtube.com/playlist?list=PLrpAqXzEvTywhUJeGwgsnt77wczx51PHH ______________ Онлайн-школа с 1 по 11 класс – это образование в любой точке мира с аттестатом государственного образца.
