Economic
consequences of the ground degradation
Republic of
Kazakhstan is the large country in territory. Its typical feature is that it is
acute continental and with dry climate and development on the vast plain parts
of the steppe and desert landscapes. Approximately 45,5 % of the territory is
occupied by steppe and 50% by desert spaces, ecosystems of which are vulnerable
enough to the anthropogenic influence. It is one of the main natural reasons of
deserting by extensive economic activity.
The natural resources development in
last centuries was mostly connected with bringing in economic rotation of vast
territories which brought to considerable changes in previously existed
landscapes.
Intensive soil development, low degree
of agricultural use culture and preventive environmental measures by
inconsiderable area of natural reserve funds furthered the deserting
development in our republic that lead to the plant cover degradation,
exhaustion of ploughed lands, change of the soil water regime and erosion.
Land utilization was lead with
inconsiderable breach of the land resources till the end of the 19th
century on the territory of Kazakhstan. The traditional methods of lands use have been system of nomadic and drive-away cattle breeding.
Cattle breeders could rationally run pasture lands owing to seasonal moves, inexhaustible
use of resources. Considerable shifts had taken place in economic forms in the
19th century. Transition into the settled way of life lead to the agriculture
development. Actually mass mastering of
virgin soils for 10-15 years had destroyed steppes in the northern
regions. The processes of local and total deserting of this region have began.
During the third period of virgin soils
and fallow soils mastering 36 million hectares of land had been ploughed. Mass
plough out of the virgin soils had stimulated such negative phenomena as dusty
storms, frequent droughts and other demonstration of anthropogenic deserting.
In conditions of non-irrigated agriculture
degradation of lands takes place during the use of monocultures, plough out of lowly productive and erosion dangerous lands,
imperfection of soils protecting agricultural technique. Non-irrigated fields
of the republic compile 24 million hectares and 10,4 million hectares of them
are deserted and 17 million hectares of them are taken out from tillage due to
the humus lose,
salt, low productivity, chemical pollution, erosion.
Lands used for irrigation are also
being in unsatisfactory condition. The reason of lands degradation in the
system of irrigated agriculture is imperfection of irrigational systems and technologies
of irrigation which leads to the secondary salification of soils, water erosion and
sometimes to the formation of swamps; Presence of considerably large areas of
agricultural lands, subjected to degradation processes makes the problem of
transformation of lowly productive fields and of other lands of agricultural
use less valuable. Taking out of degraded soils from intensive agricultural use will let us
increase part of environment stabilizing fields. This kind of practice has been
being used in republic for the last ten years in connection with the refusal of
farming subjects from processing lowly productive fields and that is why areas
of fields have been sharply reduced (for more than 12,7 million hectares).
Large territories had been occupied by
firing grounds with the development of military technologies, which made them
stop being pastries. Enterprises of military industry had taken out from
agricultural rotation about 10 million hectares of fields and pastries.
The result of firing fields formation
and extension of areas of plough in the north of republic accorded by
limitations of water resources was a sharp reduction of areas used for
pastries. The population had to herd cattle on the limited territories which
lead to exhaustion of pastries and to development of herding out and erosion.
Intensive use of the raw potential of the
republic lead to the formation of large masses of degraded soils.
Changes that took place in the social
and economic way of life of the last century, excessive plough of the fields
lead to the dusty storms, catastrophic humus gab, pastures overloading and to their deserting.
Transition into the new economic relations, liquidation of the centralized
mechanism of fuel supply lead to the uncontrolled cut down of wood plantations.
Economic difficulties do not let to finance measures of environmental protection.
Nowadays the social and economic
situation had defined reduction of plough soils. 10,4 million hectares of
republic fields are deserted from the total 31,9 million hectares. The left
fields transfer into áóðüÿíèñòûå çàëåæè.
The natural ecological systems destroy
is noticed on the most part of the territory of Kazakhstan as a result of its
irrational use. Having got an enormous territory (2,72 million square metres)
and comparably less population (about 15 million people) Kazakhstan have come
across with large ecologic problems on the entrance of the second millenium.
These processes directly or indirectly influence
The chemical industry development on
the base of backward technology and an excessive quinization lead to the ground
pollution. Technogenic breaches unavoidable during the building works, useful
mineral resources extraction cause definite damage to the ground fund of the
republic. The area of technogenically infringed grounds compile 181,3 thousand
hectares.
All the previously said lead to the
widely scoped deserting, the ground resources ecologic degradation accorded by
deduction of natural ecological systems productivity and population health
deterioration. As the world practice shows, it is not possible to supply
permanent economic development on account of environment destroy and natural resources exhaustion and also not to
save necessary quality of the environment without strong economics.
One of the major factors influencing
the problem of deserting is an economic and social development of the
population as the reason of the environment condition deterioration and natural
resources exhaustion can be both insufficient economic development and
excessive economic growth. Kazakhstan is the great oil exporter and has got
enormous reserves of energetic and mining mineral resources. The main role in
industrial sector is played by mining branch and in agriculture by cereals
plantation. Economic indices of development including inner boulder product has
got a permanent tendency for growth. The positive tendencies of developing
production and financial sectors must be directed to realization of measures
complex on social programs support since the following two reasons as village
population poverty and overpopulation lead to excessive loading on natural
systems: pastures areas reduction and their qualitative degradation; productive
ground loss. On the other hand economic growth often leads to ground resources
degradation.
So Kazakhstan has come across a problem
of preventing further degradation of ground resources and taking concrete
measures on their reconstruction, production of normal inhabitation environment
for human himself. A fight against deserting must be realized in accordance
with scientifically proved actions plan, firstly by elimination of principle
reasons, bringing deserting, definition of measures on elimination and
extirpation of these phenomena.
A fight against deserting is the
problem of people’s prosperity
permanent development promotion by elimination of ground degradation, rise of
its productivity, provision safety and political stability guarantee. The
strategic goal of the state policy of the Republic of Kazakhstan is becoming a
guarantee of favorable inhabitation environment for human on the base of manufacture optimal development, ground
resources rational use by obligatory term of keeping biological variety and
their reproduction ability.
