"Environmentalists are worried about the changes in the
landscape of Lithuania: it used to resemble a mosaic, but now it is turning
into a whole, uniform area of land, similar to steppes.
The report on the
state of the environment prepared by the European Environment Agency indicates
that one of the main reasons for the loss of biodiversity and the breakdown of
ecosystems in Europe is an excessively intensive agricultural activity, reports
the Ministry of the Environment.
Due to it, the
diversity of the landscape in agro-ecosystems is also disappearing, and the
barrier functions of ecological compensation are weakening. At the same time,
the quality of the soil deteriorates, as mechanical erosion of the fertile soil
layer increases due to plowing in the hilly landscape, there is a risk of wind caused erosion, as well as erosion caused by water.
As in many other regions of the EU, the areas of fields sown
with monocultures are expanding in Lithuania, and meadows are being plowed up.
Streams straightened during the Soviet era (more than 90% of natural water
courses were changed) and their valleys and vegetation were not given the
opportunity to return to a more natural state, because the aim is to constantly
renew the melioration systems.
The areas of perennial meadows are rapidly decreasing in
Lithuania: in 2015 668 thousand ha. of them were declared, and in 2021 - only
601 thousand ha. Meadows are turned into arable land. And when natural meadows
are plowed, ecological relationships formed over decades are destroyed, sensitive
and rare species that have established themselves in highly specialized
ecological niches disappear, natural habitats of wild pollinators and enemies
of plant pests are lost.
The condition of
meadow habitats is also deteriorating. According to the Habitats Directive 2019
report, there is not a single type of meadow habitat of European Community
importance in Lithuania, whose conservation status would be assessed as
favorable. This is also caused by the abandonment of meadows, then they are
covered with bushes and trees, they are no longer suitable for many species of
insects and birds typical of meadows, the species composition of the habitats
changes, and they degrade. Therefore, extensive grazing or mowing is necessary
to maintain natural grassland habitats.
One of the widely used indicators of the biodiversity status
of agricultural land is the rural bird population index. The last report
prepared by Lithuanian ornithologists shows that in 2016-2018 during the
period, the populations of even 10 bird species decreased, one increased and
three more remained stable. Of course, the impoverished landscape is not the
only reason, but it certainly contributes to the loss of bird species common to
the rural landscape.
In the national
landscape management plan in Lithuania, 4 problematic environmental landscape
areas have been identified, which cover about 17 percent of territories of the
country. Most of them are located in agricultural areas - this is the major
part of Suvalkija, the whole of Northern Lithuania, the lower Nemunas and
separate parts of the Central Lithuanian Plain.
The most impoverished,
ecologically inferior areas of the natural framework are concentrated in these
areas, as well as water bodies squeezed by arable fields. In them, soil erosion
must be better managed, landscape mosaicism must be increased, only
well-thought-out renovation of drainage systems based on modern solutions
should be carried out. Special attention should be paid to the restoration of
natural watercourses.
For degraded areas of the agricultural landscape, where
agricultural land accounts for more than 80 percent from the area of the
entire territory, and where there are negative changes in the state of soil,
surface and underground water, biological diversity, the aforementioned
document proposes means of spontaneous or artificial restoration.
In the highlands, in
order to restore eroded soils, the conversion of arable to non-arable
agriculture is proposed, the use of soil-improving measures that enrich the
organic matter of the soil is encouraged, and the areas of meadows and pastures
are expanded. In the plains, where wind erosion is relevant, it is proposed to
divide the monoculture fields into smaller ones, increase the areas of
perennial meadows, plant trees - protective strips of the fields.
Restoration of landscape elements is a long-term work. It is
very important to educate farmers on what kind of economic activity contributes
to the preservation of the landscape, and to increase their environmental
awareness. If you start applying measures to improve the landscape earlier, you
will win because favorable conditions for farming will be created sooner. In
addition, the quality and aesthetic appearance of the living environment of
farmers and their families will improve.
In the new financial period of the Common Agricultural
Policy, Lithuania will especially promote the preservation and restoration of
landscape elements. For this, the Lithuanian Agriculture and Rural Development
2023-2027 the strategic plan envisages the preparation of eco-schemes, with the
help of which farmers will be rewarded for nature-friendly farming focused on
improving the environment and landscape."
