Opis:: Potential water resources in the upstream part of the Komering sub-watershed, in March each year ranges from 645.49 m³/sec. With a debit of that size, it should be able to increase national agricultural production in South Sumatra, Indonesia. However, in August – September, the discharge of water availability in the upstream part of the Komering sub-watershed decreased to only 43.08 m³/sec. To analyze the reduced mainstay discharge of the Upstream Komering sub-watershed, due to poor land use practices in the upstream area and the effects of climate variability, it can be analyzed by analyzing land cover conditions, the value of rain variability, and the magnitude of evapotranspiration and validation of direct measurement of river discharge in the field. Changes in land use for the upstream part of the Komering sub-watershed, which are used mostly by residents as community plantation areas, have increased the critical condition of the upstream Komering sub-watershed area of 2,517,560 Km², or about 65.66% of the total upstream Komering sub-watershed. From the measurement of debit data at the Perjaya Dam in the last fifteen years (2005–2019), the largest main discharge value in 2 weeks to two months in April was 241.67 m³/sec, while the smallest mainstay discharge occurred in the first 2 weeks of October at 54.69 m³/sec. A large difference between the largest and smallest mainstay discharge, it is necessary to think of a way so that the availability of water is always maintained throughout the year (the difference between the mainstay discharge between the rainy season and the dry season so that it is not so extreme). Some ways that can be done to maintain the availability of water include making a reservoir that can be used during the dry season, or increasing storage in the soil by reforestation and harvesting rain.

Opis:: Tracking and analysing economic and social changes in the agricultural sector is vital for decision makers, sectoral parties, professional and advocacy organisations and research institutions. Collected statistical data serve as a basis for domestic decision making and provide the foundation of strategy formulation in rural development, agro-environmental protection and sustainable agriculture. In the course of our research, analyses based on statistical databases were used to assess land use changes and land market prices. The structural survey of the Hungarian Central Statistical Office in 2013 shows that the proportion of business organisations utilising arable land grew 7 percentage points while individual farms increased their share by 2 percentage points. Our research shows that the concentration of land use increased demand for land and thus contributed to the increase in land prices.
Śledzenie i analiza zmian ekonomicznych i socjalnych w sektorze rolnym jest niezbędne dla osób podejmujących decyzje, organizacji zawodowych oraz instytucji badawczych. Zebrane dane statystyczne służą za podstawę do podejmowania lokalnych decyzji oraz formułowania fundamentalnej strategii dotyczącej rozwoju rolnego, rolnośrodowiskowej ochrony oraz rolnictwa zrównoważonego. W badaniach wykorzystano dane z bazy statystycznych, aby ocenić zmiany w użytkowaniu ziemi oraz jej cen rynkowych. Ze sprawozdania Węgierskiego Głównego Urzędu Statystycznego z 2013 roku wynika, że udział organizacji biznesowych użytkujących grunty uprawne wzrosła o 7 p.p., podczas gdy prywatne gospodarstwa rolne zwiększyły swój udział o 2 p.p. Badanie pokazały, że koncentracja gruntów zwiększa popyt na nie, ale przyczynia się także do wzrostu cen.

Opis:: The paper looks into the issues related to the monitoring of land use change by voivodeship marshals in Poland. The author intended to provoke the academic circles to devote more attention to this matter as well. The analysis involved the publicly available materials and the information from websites of 16 marshal offices and Polish acts of law made available in the Online Database of Legal Acts. The paper includes an analysis of the changes in land use monitoring legislation in Poland and when the obligation was first introduced. It was further verified whether all the offices publish the documents relevant to the monitoring. It was found out that half of the voivodeships failed to publish the materials related to the performance of this statutory task. This results in a varied availability of the documents and prevents potentially interested parties from familiarising themselves with the land use change monitoring issues.

Opis:: Quantifying and understanding global land use change and its spatial and temporal dynamics is critical to supporting international policy debates. The main area of transformation of spatial structures nowadays are suburban areas of the largest cities. Constant land development and urbanization, including such forms as urban sprawl, influence significant changes in land use. The aim of this study was to analyse a land use change pattern in a selected rural area which is under pressure of spatial development of a regional city. Data used for a land use change detection was based opensource Urban Atlas dataset for 2006, 2012, and 2018, enriched by recent update from 2021 orthophoto map. Spatial analyses presenting statistics of land use change were conducted in QGIS. Besides analysis of land use change, the paper discusses observed spatial patterns also taking into account changing social, environmental and economic conditions and spatial policies influencing land cover complexity. Understanding these dynamics would help better spatial management of real estates for more sustainable land development.

Tytuł:: Land use change impact on soil organic matter. Loess landscape case study

Tematy:: Land use change

Loess landscapes
Opis:: The aim of this article is to establish how land use change influences soil organic matter content in the loess landscape. The research was conducted near Krasnystaw in the Lublin Upland, in forest, on arable land and on abandoned lands at various stages of secondary succession. During the field research, samples were collected from the upper soil layer and analyzed for organic carbon content, fractional composition of humus compounds and soil reaction. The results obtained indicate that the impact of land use change manifests itself in a change of the soil reaction, which turns from neutral or slightly acid into acid. The tillage system reduces organic matter in the soil and increases the humic acids ratio, whereas abandonment of the land causes an evident increase in the soil’s organic matter content and the fulvic acids ratio. These results allow us to state that land use change has a rapid impact on the geochemical properties of the landscape (which can be noticed as soon as 5 years after the land is abandoned).

Opis:: This paper investigated the impact of land use/cover changes on the flow of the Zarqa River in Jordan over a period of twenty-eight years. The land use/cover maps were derived using a set of medium spatial images with full scenes for the years 1989, 2002, 2011 and 2017. These images correspond to the river flow data for the same hydrological rainy seasons. The component of the river flow consists of the base-flow, flood and contribution of effluent from treatment plants. Base-flow was separated from hydrographs and effluent contribution was obtained. Runoff coefficient was determined as the ratio of flood volume to rainfall volume. The land use/cover maps were classified as urban fabrics, bare rocks, open rangelands and bare soils, agricultural areas, agro-forestry, and water bodies. During the study period, urban areas increased from 4.87% to 16.14%, and agricultural areas increased from 21.69% to 31.66%. The areas of rangelands and bare soil decreased from 34.91% to 22.57% and bare rocks from 35.98% to 27.57%, respectively. The increase in urban and agricultural areas resulted in runoff coefficient improvement from 1.89% in 1989/1990 to 2.72% for 2016/2017. The results could be useful for planners and decision makers for future flow management in the Zarqa River Basin. The approach and results of this study confirm the findings of similar studies for land and water management.

Opis:: Land cover change (LCC) is important to assess the land use/land cover changes with respect to the development activities like irrigation. The region selected for the study is Vaal Harts Irrigation Scheme (VHS) occupying an area of approximately 36, 325 hectares of irrigated land. The study was carried out using Land sat data of 1991, 2001, 2005 covering the area to assess the changes in land use/land cover for which supervised classification technique has been applied. The Normalized Difference Vegetation Index (NDVI) index was also done to assess vegetative change conditions during the period of investigation. By using the remote sensing images and with the support of GIS the spatial pattern of land use change of Vaal Harts Irrigation Scheme for 15 years was extracted and interpreted for the changes of scheme. Results showed that the spatial difference of land use change was obvious. The analysis reveals that 37.86% of additional land area has been brought under fallow land and thus less irrigation area (18.21%). There is an urgent need for management program to control the loss of irrigation land and therefore reclaim the damaged land in order to make the scheme more viable.

Opis:: For the good established landscape planning landscape protection and landscape management actions have to take into consideration the actual conditions of the landscape elements. Earlier we dealt with the stability of the landscapes (Kerényi, Csorba, 1996), recently started to investigate the most important factors, which are endangers the proper functioning of the landscapes. Results are calculated for 229 microregions of the country, which are elements of the official landscape hierarchy of Hungary described in the Cadastral of Microregions of Hungary. The average size of the microregions are 100-500 km2. There are certain factors among which some have already elaborated, and others are being worked on yet. Degree of ecological fragmentation of the microregions by roads, railway lines and settlements was determined during the last year. In the case of large settlements the extent of inner parts, traffic intensities of the roads was taken into account, while in the case of railroads it was taken into consideration whether railway lines are single or double tracked. Results were purified using a weighting, where the location of the protected natural areas compared to the situation of the given settlement, roads or railroads was taken into consideration. In the calculations it was taken into account as well that the agglomeration processes of the large settlements may restrict the ecological gates and corridors of the migration of plant and animal species. From the series of maps on natural threats on microregional level, the map of the hazards of drought is presented first. The map gives a definite answer to the question, in which microregions is profitable to establish irrigation systems; and how high is the uncertainty of the rate of their utilization. Global warming, however, may modulate the map resented here remarkably in the next decades. Microregions that have been classified into transition categories with moderate or medium level of drought hazard may fall into categories of serious hazard of drought in the future. A synthesizing map has been completed by summing the seven datasets of the indicator group of natural hazards and the weighting of the subsets. Landscape planning is strongly affected by tendencies of macro economy on the present land use structure. EU agricultural policies have just started to affect strongly on Hungarian land use structure, therefore attempts have been made in order to forecast their impacts. Present Hungarian land use structure has been compared to priorities of the EU. Prospective shifts in land use structure have been determined for the 35 regions of Hungary. According to the 8-10 factors mentioned above, we shall have a detailed database to evaluate the microregions of Hungary in order to characterize the most threatened landscapes, and the most dangerous impacts on the landscape functioning.

Opis:: The northeastern region of India, with an area of 255 090 km2, is predominantly hilly. Major socio-economic factors affecting sediment production in the region are; shifting cultivation, land tenure system, fast growing population, small land-holdings, deforestation and free range grazing. A multi-disciplinary long- -term study showed that 92.9 to 99.1% of rainwater can be retained in-situ, compared to 66.3% in shifting cultivation. Mean annual soil loss varied from 11.2 to 97.2 t km–2 in new land use systems as against 3621.3 t km–2 in shifting cultivation. The sediment load per litre of runoff from watersheds varied from 1250–20,300 mg suspended sediment, 5.4 to 23.6 mg NO3 – N, 2.3 to 6.5 mg P–PO4, 17.2 to 35.8 mg K2O, 0.4 to 1.8 mg Zn, 0.9 to 2.7 mg Mn, 6.5 to 12.0 mg Mg, 7.1 to 18.4 mg Fe and 4.0 to 7.2 mg SO4. The sediment transport from the catchments showed spatial and temporal variations.
W pracy przedstawiono analizę czynników wpływających na wytwarzanie rumowiska w północno-wschodnim regionie Indii. Do głównych czynników naturalnych można zaliczyć wysokie opady deszczu (średniorocznie 2450 mm) oraz duże nachylenie terenu w zlewniach, dochodzące do 32–53%. Wśród czynników antropogenicznych jako istotne wskazuje się: duży udział gruntów ornych, duże rozdrobnienie i system własności gospodarstw rolnych, postępujące wylesianie oraz swobodny wypas bydła. Stwierdzono, że w wyniku przekształcenia gruntów ornych na inne użytki rolne wzrośnie retencyjność zlewni, a ilości odpływającego rumowiska zmniejszy się o ok. 90%. W tym celu konieczne są działania o charakterze prawnym, planistycznym, z zakresu gospodarki wodnej i zagospodarowania terenu.
