Challenges of Establishing Green Corridors in the Areas with Agricultural Land Consolidation

Conducting land consolidation within an area where agricultural land has the largest share is of great importance. Current practice of enforcing land consolidation was focused upon achieving favorable conditions for agricultural production, simultaneously leading to negative effects related to the environment, wildlife and native species. The aim of land consolidation is achieving favorable conditions for agricultural production, which can be obtained through the grouping of properties and the formation of larger plots of proper shape. In order to accomplish these effects, barriers which might interfere with agricultural operations (e.g. forest vegetation and non-functional amelioration canals) must often be removed. Especially drastic measures of clearing the terrain are required if mobile equipment for irrigation is planned on new plots. However, in the context of the integral land consolidation both effects can be achieved, i.e. improved conditions for agricultural production, as well as positive effects related to the environment. Vojvodina is a northern province of Serbia where 76% of arable land is exploited in agriculture, while forested areas cover only - about 6% (Marković and Tatalović, 1995). The implementation of land consolidation, in most of cases led to even more reduced presence of non-forest vegetation within the area. During implementation of the measures, the regulation was mainly done by removing non-forest vegetation. Compensation for non-forest vegetation, or segregation area for afforestation, in most cases has not been included in the project design. During the second half of the last century, more than 56% of the territory in Vojvodina has been regulated by applying land consolidation measures (Damjanović and Benka, 1994). Unfortunately, the implementation of land consolidation measures was focused mostly upon establishing favorable conditions for intensive agricultural production and often led to reduction of non-forest vegetation. Nowadays, forested areas within arable land, where intensive agricultural production is applied, cover only 1.5 % (Letić et al., 2001). Due to unilateral approach of land consolidation, later efforts were focused upon improving environment by planning implementation of subsequent measures - raising windshield forest belts. The paper presents the results of the analysis of spatial representation, distribution and interconnectivity of nonforest vegetation within an area where land consolidation was performed. Outcome of these measures was compared to the situation after introducing windshield forest belts

Utvrđivanje zastupljenosti i povezanosti vanšumskog zelenila na komasacijom uređenom području

Uređenje zemljišne teritorije putem komasacije ima za cilj poboljšanje uslova za poljoprivrednu proizvodnju. Poboljšanje se ogleda u grupisanju razbacanih i rascepkanih poljoprivrednih poseda u veće parcele. Nove parcele su pravilnog oblika, pogodnog za obradu savremenom poljoprivrednom mehanizacijom, sa direktnim pristupom sa mreže poljskih puteva. Kako bi se formirale pravilne parcele sa grupisanim posedom, na području je neophodno izvršiti čišćenje od skoro svih oblika vanšumskog zelenila, koje u novoj parcelaciji predstavlja prepreku. Prisustvo vanšumskog zelenila na području sa velikim procentom obradivih poljoprivrednih površina je od izuzetnog značaja. Funkcije vanšumskog zelenila se ogledaju od zaštite zemljišta od isušivanja i eolske erozije, očuvanja biodiverziteta do formiranja izgleda predela. U radu je prikazana mogućnost utvrđivanja zastupljenosti i povezanosti vanšumskog zelenila koristeći satelitske snimke dostupne preko aplikacije Google Earth. Identifikovane površine pod vanšumskim zelenilom su razvrstane kao tačkasti, linijski i površinski elementi. Korišćenjem geografskog informacionog sistema utvrđena je zastupljenost, međusobna povezanost i prostorni raspored vanšumskog zelenila na komasacijom uređenom području opštine Ada. Stanje registovano sa satelitskih snimaka je upoređeno sa stanjem koje bi se dobilo realizacijom projekta podizanja poljozaštitnih šumskih pojaseva

The effects of elevated summer temperatures on content of pesticide residues in SNR "Obedska Bara"

A special nature reserve Obedska Bara is a world famous swamp area which has been, throughout its long history, a true home for plants and animals and a center of attention of many explorers, scientists and nature lovers. It appeared more than several thousand years ago and since then many things have changed. Given that Obedska Bara is surrounded with agricultural land, there is a possibility that the swamp could be polluted with pesticides. The aim of this study was to highlight the influence of elevated summer temperatures on the content of pesticide residues in SNR „Obedska Bara“. Sampling was carried out at the end of July and August 2017. Pesticide analysis of 90 pesticides was performed by using LC/MS-MS detection. The obtained recoveries were from 69.8 – 114.7% with the relative standard deviation of 2.28 – 11.7% for all investigated pesticides. The obtained limits of quantification - LOQs for all twenty-one investigated pesticides were 0.010 µg/L. The results of pesticide analysis in a water sample from Obedska Bara indicate the presence of 8 pesticides. Just one of them was detected at levels exceeding maximum allowable concentrations –MACs

Water quality at special nature reserves in Vojvodina, Serbia

Although protected, special nature reserves are not isolated from anthropogenic influences entering from outside their borders. Water quality is particularly endangered at three special nature reserves in Vojvodina, i.e. Ludaško jezero (Ludas Lake), Carska bara (Imperial Pond) and Obedska bara (Obed Pond). The special nature reserve Obed Pond and Ludas Lake are polluted by agricultural runoff and untreated wastewater resulting in serious eutrophic processes, and the SNR Imperial Pond is potentially influenced from nearby fish pond and agriculture. The monitoring conducted in summer and in autumn in 2016, at the three mentioned special nature reserves, included water sampling on several locations within each protected area. The analyses included basic water quality parameters, microbiological analyses, as well as water mineralization. Both, water quality and microbiological results, have proven the presence of eutrophic processes at all analyzed protected areas, but the worst conditions were detected in the North and Middle of the Ludas Lake. Considering the other two investigated protected areas, results are a bit better indicating moderate eutrophic conditions
