1 Land cover 2006 Overview of land cover & change consists of two regions with significantly different character of the landscape. Lowland region of Vojvodina, situated in the northern part of the country, has agricultural character with prevailing share of arable land and complex cultivation patterns and high concentration of artificial areas. In contrast, the southern part of the country is covered mainly by forests and other natural land cover types and by pastures. Also the spatial distribution of land cover changes is different for both parts of the country. Vojvodina is characterized by higher changes density, with forest and agricultural change areas concentrated mainly along major rivers (Dunav and Tisa). In the southern part of the country, change areas are uniformly scattered over the landscape. Artificial land take occurs mostly in the surroundings of capital city Belgrade and other major cities like Novi Sad, Nis, and Subotica. Besides, there is also noticeable artificial sprawl connected with development of two major mining localities in central (near Lazarevac and Pozarevac). Compared to the previous period, the overall change dynamic in n landscape significantly decreased during. It is caused mainly by lower intensity of forest and internal conversions, which are the main drivers of landscape development in. In contrast, artificial land take, which has been driven mostly by sprawl of economic sites and infrastructures, accelerated. Forested land remains the land cover type with highest area turnover. However, formation of forested land is driven mostly by internal conversion from transitional woodland to forest due to regular forestry activities. The overall structure of agricultural surfaces exchange has been totally turned over during. In the previous period, there was significant consumption of arable/crop land and formation of pastures and mosaics. In contrast, the period is characterized by positive balance of arable/crop land area and prevailing consumption of pastures/mosaics. The other significant drivers of land cover exchange in are conversions from forested/natural land to and water bodies creation and management. Note: The results presented here are based on a change analysis of 44 land cover types mapped consistently on a 1: scale across Europe over almost two decades see Corine land cover (CLC) programme for details.

3 Artificial areas 3.8. A rt if icial land take [ha/year, % of initial year] % 0.28% Accelerated extension of mines and quarrying Overall artificial land take in slightly accelerated, compared to the previous period. This acceleration has been driven by sprawl of mines and quarrying areas (47%), which has been doubled compared to the previous period. In contrast, the intensity of diffuse residential sprawl (37%), which was the major driver of artificial land take during the previous period slightly decreased. However, this flow still remains the second most powerful driver of land take in. These two main drivers are accompanied (to a lesser extent) by sprawl of industrial/commercial sites (8%), construction (4%), and dump sites (4%). Mainly agricultural areas (74%), with prevailing share of pastures and mosaics (53%), followed by forested land (25%) have been taken by artificial sprawl. Also, the intensity of urban land management, represented mainly by conversion of construction sites into discontinuous urban fabric, increased compared to the previous period. Beside the land take, artificial areas were also consumed by forest creation over former mineral extraction sites A rtif icial surf aces 2006 [% of total area] A rt if icial land t ake [ha/year] 7% 4% % Mean annual artificial change by class [ha/year] Continuous urban fabric Discontinuous urban fabric Industrial or commercial units Road and rail networks and associated land Port areas Airports Mineral extraction sites Dump sites Construction sites Green urban areas Sport and leisure facilities 3

4 Agriculture Dynamic development of agricultural land in Vojvodina The situation in development of agricultural surfaces has stabilized during, which is documented by decrease of area turnover of both pastures/mosaics and arable/crop land. The structure of net change balance between arable land and pastures is completely opposite to the previous period, with prevailing formation of arable land. The other main contributor of arable land formation is the conversion from vineyards and orchards to nonirrigated arable land, which became the second most powerful driver of internal agricultural change in.. Besides the internal conversions, which are the main driver of change in n landscape, the development of agricultural land has been also influenced by various external flows. The most significant of them is artificial land take, namely urban residential sprawl, followed by sprawl of mineral extraction sites and sprawl of industrial and commercial units. Exchange between and natural surfaces has been represented mainly by formation of agricultural land through conversions from dry semi-natural land or forest (mostly natural grassland and transitional woodland areas). In contrast, agricultural areas have been consumed through water bodies creation and also through withdrawal of farming (mostly with transitional woodland creation). Most of agricultural conversion occurs in northern part of the (Vojvodina region) A gricult ural areas 2006 [% of total area] % % % 0.33% Development of agricultural areas detailed balance [ha] C onsumption of initial land cover Formation of new land cover 0.10% 3.03% 0.39% 0.03% -4.33% % -2.67% % % 231 4% Non-irrigated arable land Permanently irrigated land Rice fields Vineyards Fruit trees and berry plantations Olive groves Pastures Annual/ permanent crops Complex cult. patterns Agriculture with nat. veg.

These conversions between transitional woodland and standing forests due to forestry activities are the main drivers of change not only within forested land, but also within whole n landscape. However, the intensity of conversion from transitional woodland to forest decreased significantly, compared to the previous period, which causes negative net change balance of forested areas. Net change balance of other non-forested natural land cover classes is characterized by consumption of natural grasslands, restoration of burnt areas and formation of water bodies and water courses. Natural land, with prevailing share of natural grasslands (more than 50%) and transitional woodland, has been consumed mostly by arable land (over 60%) and by extension of mineral extraction sites. On the other hand, new transitional woodland and water bodies have been formatted over agricultural land or mineral extraction sites Development of forest & nature areas detailed balance [ha] % 1.04% % % % -0.58% -0.10% -1.00% -2.09% % % -0.74% C onsumption of initial land cover Formation of new land cover Broad-leaved forest Coniferous forest Mixed forest Natural grassland Moors and heathland Sclerophyllous vegetation Transitional woodland Beaches, dunes, sand Bare rock Sparsely vegetated Burnt areas Glaciers/perp. snow Inland marshes Peatbogs Salt marshes Salines Intertidal flats Water courses Water bodies Coastal lagoons Estuaries Sea and ocean Mean annual forest & nature change by class [ha/year] Broad-leaved forest Coniferous forest Mixed forest Natural grassland Moors and heathland Sclerophyllous vegetation Transitional woodland Beaches, dunes, sand Bare rock Sparsely vegetated Burnt areas Glaciers and perpetual Inland marshes Peatbogs Salt marshes Salines Intertidal flats Water courses Water bodies Coastal lagoons Estuaries Sea and ocean 5
