Opis:: Climate, land use, and land cover change can propagate alteration to the watershed environment. The interaction between natural and human activities probably accelerates the change, a phenomenon that will generate serious environmental problems. This study aims to evaluate the change in the hydrological regime due to natural and human-induced processes. The study was conducted in Brantas watershed, Indonesia, which is the largest watershed in East Java. This area is populated by more than 8 million inhabitants and is the most urbanized area in the region. An analysis of rainfall time series use to shows the change in natural phenomena. Two land-use maps at different time intervals were used to compare the rapid development of urbanization, and the discharge from two outlets of the sub-watersheds was employed to assess hydrological changes. The indicator of hydrological alteration (IHA) method was used to perform the analysis. The daily discharge data are from 1996 to 2017. The research results show an increase in flow (monthly, 1-day, 3-day, 7-day, 30-day, and 90-day flows) in the two sub-watersheds (Ploso and Kertosono) from the pre-period (1996–2006) to the post-period (2007–2017).

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.

Opis:: Despite many studies on the hydrological responses to forest cover changes in micro and mesoscale watersheds, the hydrological responses to forest cover alterations and associated mechanisms through the large spatial scale of the river watershed have not been comprehensively perceived. This paper thus reviews a wide range of available scientific evidence concerning the impacts exerted by the forest removal on precipitation, water yield, stream flow, and flow regimes. It is concluded that there is no statistical correlation between forest cover and precipitation and water yield at the micro and mesoscale. In contrast, there is a relative correlation coefficient (r = 0.77, p < 0.05) between forest cover and water yield at large scales (>1000 km2). These findings help our understanding of the hydrological response to forest disturbance at large and regional scale and provide a scientific perception to future watershed management in the context of human activities and natural hazards.

Opis:: The international community affirms the critical role of forests in climate change mitigation, which includes reducing emissions from degradation and deforestation, carbon stock conservation, sustainable forest management, and increasing carbon stocks in developing countries. It relates to land use and land cover changes. This study aims to review land use and land cover changes (LULC) in two decades, namely 2000-2010 and 2010-2020, and the impact on carbon stocks. Landsat satellite imagery in 2000, 2010, and 2020 are classified into six categories: built-up area, cropland, forest, water body, bareland, and grassland. This classification uses supervised classification. The accuracy kappa coefficient values obtained for the LULC 2000, LULC 2010, and LULC 2020 maps were 89.61%, 83.90%, and 87.10%, respectively. The most dominant systematic LULC change processes were forest degradation in 2000-2020; the transition of forest to cropland (349.20 ha), forest to bareland (171.19 ha), and forest to built-up area (661.68 ha). Loss of using the forest for other uses was followed by a decrease in carbon stock. There was a high decrease in carbon stock in the forest category (11,000 Mg C∙y-1). The results showed a significant change in land use and cover. The decline in the area occurred in the forest category, which decreased from year to year. Meanwhile, the built-up area increases every year. Carbon stocks also decrease from year to year, especially forests as the most significant carbon store, decreasing in the area.

Opis:: Human activities on land have grown significantly changing the entire landscape, while most of the changes have occurred in the tropics. The change has become a serious environmental concern at the local, regional and global scales. The intensity, speed, and degree of land use / land cover (LULC) changes are nowadays quicker compared to the past because of the development of society. Moreover, the rapid increase in population resulted in disturbing a large number of landscapes on the Earth. The main objective of this study was to detect historical (1990-2020) and predicted (2020-2050) LULC changes in the Welmel River Watershed, which is located in the Genale-Dawa Basin, South Eastern Ethiopia. The dataset of 1990, 2005, and 2020 was generated from Landsat 5, Landsat 7 and Landsat 8 respectively to determine the historical LULC map. The result of this study revealed that agriculture/ settlement increased by 6.85 km2 ∙y-1, while forestland declined by 9.16 km2 ∙y-1 over the last 31 years between 1990 and 2020. In the coming 31 years (by 2050), if the existing trend of the LULC change continues, agriculture/settlement land is expected to increase from 290.64 km2 in 2020 to 492.51 km 2 in 2050 at the rate of 6.73 km2 ∙y-1, while forestland is expected to shrink from 690.48 km2 in 2020 to 427.01 km2 in 2050 by a rate of 8.78 km2 ∙y-1.

Opis:: Land use change in the upstream of Rawa Pening watershed which is more and more dominated by residence and industry causes the increasing of surface flow discharge on the rainy season. In addition, the decreasing of Rawa Pening ability in storing flood discharge also influences to the cropping area in surrounded Rawa Pening. Water surpluses occurring downstream are related to the land use change in the upstream which gives impact in the downstream. However, it is as an important reason to carry out the optimization of water economic value in this region. The disruption of water availability causes the decreasing of any production like hydroelectrical power, fresh water, and rice production, so the optimal water economy is decreasing. This research intends to: 1) analyse the effect of land use change to the water availability; 2) analyse the land use change to the water balance; and 3) build and analyse the optimization model of water economic value due to the land use change. Results show that there is the different influence of land use change during the years to the results of water value optimization.
Zmiana użytkowania ziemi w górnej zlewni Rawa Pening coraz bardziej zdominowanej przez zabudowę mieszkalną i przemysłową powoduje wzrost odpływu powierzchniowego w porze deszczowej. Malejąca zdolność Rawa Pening do retencji wód powodziowych wpływa na okoliczne tereny uprawne. Nadmiary wody występujące w dolnej części zlewni są powiązane ze zmianami użytkowania ziemi w górnej części zlewni. Ta zależność jest ważnym powodem podjęcia optymalizacji gospodarki wodnej regionu. Zakłócenia w dostępności wody powodują zmniejszenie produkcji energii elektrycznej wytwarzanej w hydroelektrowniach, wody słodkiej i ryżu, skutkiem czego maleje optymalne wykorzystanie wody. Badania miały na celu: 1) analizę wpływu zmian użytkowania ziemi na dostępność wody; 2) analizę wpływu tych zmian na bilans wodny; 3) skonstruowanie i analizę modelu optymalizacji gospodarczej wartości wody w związku ze zmianami użytkowania ziemi. Wyniki dowodzą różnego wpływu zmian w czasie na optymalizację wartości wody.

Opis:: The cartography and quantification of irrigated fields in the context of decreasing rainfall constitute a key element for water resources management. Therefore, in this context, the use of remote sensing methods applied to Landsat-type images with a high spatial resolution for monitoring the changes in land use in general and irrigated crops, in particular, is highly relevant. This paper aims to present a method for mapping spatial and temporal changes in irrigated parcels in the Guigou Plain, located in the central Middle Atlas, based on Landsat images and fieldwork. For the years 1985, 1998, 2010 and 2018, the use of a supervised classification method based on the principle of machine learning, fed by precise field surveys, has made it possible to highlight a significant extension of irrigated areas to the expense of pastureland and rainfed crops. Over the entire period under consideration, the results obtained with good precision (98.5% overall accuracy) showed that the area under irrigated crops has increased from approximately 699 ha to 3988 ha, i.e. an increase of 570%. The corollary of this increase is strong pressure on the water resource, especially groundwater. This information on the total extension of irrigated plots can be taken as a reference in the perspective of reasoned management of water resources in the sector.

Opis:: A flood occurs for many reasons, such as excessive rainfall, runoff coefficient, or an insufficient river channel capacity. The discharge flowing through the floodway depends on the maximum main river dimension that can be normalized. LU/LC changes are affected by runoff discharge, and runoff discharge is affected by the floodway design. The study discusses the effect of land use (LU) or land cover (LC) changes and the design of floodway channel dimensions in the Kali Kemuning watershed, East Java Province, Indonesia. The Nakayasu synthetic unit hydrograph has been used to analyse the runoff discharge, and the Hydrologic Engineering Center’s River Analysis System software analysed the hydraulic properties of river and floodway channels. Results show that the floodway channel design is determined by LU/LC conditions, and the river channel is normalized toward its maximum dimensions. Normalized channel depths and widths vary from 4 to 7 m and 16 to 46 m, respectively. The floodway channel is rectangular, with a bottom width of 10 m and depth of 4.5 m. With the runoff coefficient equal to 0.75, these normalized channel and floodway dimensions are suitable for the flood up to the 100-year return period runoff discharge.

Opis:: Water erosion in mountainous areas is a major problem, especially on steep slopes exposed to intense precipitation. This paper presents the analysis of the topsoil loss using the SWAT (Soil and Water Assessment Tool) model. The SWAT model is a deterministic catchment model with a daily time step. It was designed to anticipate changes taking place in the catchment area, such as climate change and changes in land use and development, including the quantity and quality of water resources, soil erosion and agricultural production. In addition to hydrological and environmental aspects, the SWAT model is used to address socio-economic and demographic issues, such as water supply and food production. This program is integrated with QGIS software. The results were evaluated using the following statistical coefficients: determination (R2), Nash-Sutcliff model efficiency (NS), and percentage deviation index (PBIAS). An assessment of modelling results was made in terms of their variation according to different land cover scenarios. In the case of the scenario with no change in use, the average annual loss of topsoil (average upland sediment yield) was found to be 14.3 Mg∙ha-1. The maximum upland sediment yield was 94.6 Mg∙ha-1. On the other hand, there is an accumulation of soil material in the lower part of the catchment (in-stream sediment change), on average 13.27 Mg∙ha-1 per year.

Opis:: Perceiving the spatiotemporal relationship of land use changes and groundwater resources is crucial for the effective and sustainable management of the plains. This study aims to investigate the relationship between land use changes and groundwater depth fluctuations in the forbidden plains of northern Hamedan. In the present study, the land use maps for 1989, 1997, 2005, 2013 and 2018 were extracted and categorized from Landsat satellite images and then evaluated for accuracy. In addition, groundwater depth distribution maps were prepared by kriging method for five years from piezometric data. The correlation and relationship between land use changes and groundwater depth fluctuations were determined by REGRESS methods. The findings from kriging method indicated that the intensity of groundwater decline during the last three periods of study (2005, 2013 and 2018) becomes more severe in the study area. Land use change trends indicate a sharp decline in the orchards, pasture lands, barren lands and a relative decline in the irrigated agricultural land, and consequently, increasing in non-irrigation and residential farmland. In addition, the average annual depth of groundwater level during the past 29 years decreased to 1.57 m and 0.87 m in the Kabudrahang and Razan Plains, respectively. The r value of REGRESS method during five study periods was the minimum 0.015 and maximum 0.15 in the Kabudrahang Plain and minimum 0.06 and maximum 0.15 in the Razan Plain, respectively. The results of the study indicated that climate changes cannot be considered as the reason for declining the groundwater in the study area. However, along with the relative impacts of land use changes, the role of managerial factors, the prominent example of which is the non-expert location of the Shahid Mofatteh Hydroelectric Power Station, which supplies underground water to cool the generators, should be considered. The present study can be effective in the management, planning, and policy of groundwater resources, land use location, and spatial planning in the areas facing severe water shortages, especially in the northern plains of Hamedan because this study indicates the importance of underground water in arid and semi-arid regions.

Opis:: Building permit decisions are one of the most important elements of the investment process in Poland. It should be noted that water reservoirs influence the diversification of landscapes by increasing their attractiveness in both urban and rural areas. The article aimed to verify the relationship between the changes in land-use development and investments related to small retention. Another goal was classifying objects for which building permits have been obtained and registered. Changes in land-use development associated with the introduction of ponds, which blend in with the landscape, are desirable from the perspective of retaining water resources in urban and rural ecosystems. The research methodology was based on spatial data and included statistical analyses in three regions: Mazowieckie, Lodzkie and Swietokrzyskie. Studies carried out in these regions showed a spatial correlation associated with investments in small retention. The research used methods of the global I Moran statistic and local Moran statistics. The data used in the study came from the Register of Applications, Decisions and Notifications, made available by the Main Office of Construction Site. The research indicates clusters of investments in small retention in analysed regions. The majority of investors are residents who invest in earth ponds. The study shows that investment in small retention is connected with ecosystem services.

Opis:: This paper presents results of object-oriented classification of Landsat ETM+ satellite image conducted using eCognition software. The classified image was acquired on 7 May 2000. In this particular study, an area of 423 km² within the borders of Legionowo Community near Warsaw is considered. Prior to classification, segmentation of the Landsat ETM+ image is performed using panchromatic channel, fused multispectral and panchromatic data. The applied methods of classification enabled the identification of 18 land cover and land use classes. After the classification, generalization and raster to vector conversion, verification and accuracy assessment are performed by means of visual interpretation. Overall accuracy of the classification reached 94.6%. The verification and classification results are combined to form the final database. This is followed by comparing the object-oriented with traditional pixel-based classification. The latter is performed using the so-called hybrid classification based on both supervised and unsupervised classification approaches. The traditional pixel-based approach identified only 8 classes. Comparison of the pixel-based classification with the database obtained using the object-oriented approach revealed that the former reached 72% and 61% accuracy, according to the applied method.
W artykule przedstawiono wyniki klasyfikacji obiektowej zdjęcia satelitarnego Landsat ETM+, uzyskane z zastosowaniem specjalistycznego oprogramowania eCognition. Klasyfikację wykonano na przykładzie zdjęcia zarejestrowanego 7 maja 2000 r., obrazującego obszar badawczy o powierzchni 423 km², znajdujący się w granicach powiatu legionowskiego w pobliżu Warszawy. Proces klasyfikacji obiektowej polega na rozpoznaniu obiektów, którymi są grupy pikseli spełniające założone kryterium jednorodności. Granice obiektów zostały zdefiniowane w czasie segmentacji zdjęcia, wykonanej na podstawie wartości pikseli kanału panchromatycznego skanera ETM+ oraz danych uzyskanych w wyniku połączenia wybranych kanałów wielospektralnych z kanałem panchromatycznym. Zastosowane metody klasyfikacyjne, związane nie tylko z wartościami spektralnymi charakteryzującymi poszczególne obiekty, lecz również z kryteriami parametrycznymi, umożliwiły identyfikację 18 klas pokrycia i użytkowania ziemi. Następnie wynik klasyfikacji został przetworzony funkcjami: generalizacji, konwersji formatu danych oraz poddany weryfikacji. Generalizację wykonano z zastosowaniem jednostki odniesienia wynoszącej 1 ha dla klas zabudowy i wody oraz 4 ha dla pozostałych klas. Następnie format klasyfikacji został zmieniony z rastrowego na wektorowy, w którym wykonano wygładzenie granic wydzieleń. Klasyfikacja została zakończona weryfikacją wektorowej bazy danych metodą interpretacji wizualnej. Całkowita dokładność klasyfikacji została oceniona na poziomie 94.6%. Po uwzględnieniu zmian wprowadzonych w czasie weryfikacji uzyskano końcową postać bazy danych. Wyniki klasyfikacji obiektowej zostały porównane z wynikami tradycyjnej (pikselowej) klasyfikacji, wykonanej z zastosowaniem algorytmu tzw. klasyfikacji hybrydowej, składającej się z następujących po sobie klasyfikacji nadzorowanej i nienadzorowanej. Rozpoznano jedynie 8 klas pokrycia i użytkowania ziemi. Dokładność tradycyjnej klasyfikacji oceniono przez porównanie jej z wynikami klasyfikacji obiektowej. Uzyskano wyniki na niskim poziomie, wynoszącym jedynie 72% i 61%, w zależności od przyjętej metody oceny.

Opis:: Land use land cover change (LULC) has become part of the global science agenda and the understanding of LULC change is vital for planning sustainable management of natural resources. The study has employed multi- temporal satellite imagery to examine the LULC change in the Abbottabad District from 1989 to 2019. Images from Landsat-5, Landsat-7, and Landsat-8 Thematic Mapper (TM) for the same season were acquired from the USGS for the years of 1989, 1999, 2009 and 2019. The images were pre-processed by atmospheric correction, extraction of the study area and band composite. The supervised image classification using Maximum Likelihood Classifier and accuracy assessment were applied to prepare LULC maps of the Abbottabad District. In the last three decades, the study area witnessed number of changes in the pattern of LULC due to population growth, rapid urbanization and increased development of infrastructure, which cumulatively led to the emergence of new patterns being employed for land use. Results of the analysis involving the classified maps show that agricultural land and bare land have decreased, respectively 15.73% and 3.81%, whereas water resources have decreased significantly by 0.58%. This study reveals that GIS can be used as an informative tool to detect LULC changes. However, for planning and management, as well as to gain better insight into the human dynamics of environmental variations on the regional scale, it is crucial to have information about temporal LULC transformation patterns in the study area.

This aim was achieved by verifying of the structural data on land use in relation to an altitude a.s.l. Based on the information collected on the areas in the particular land categories, and in order to assess land use, a database was created for 99 mountain communes (NUTS-5). The regulation by the Minister of Agriculture and Rural Development (2009) distinguishes the areas of less favourable farming (LFA, mountain), where over 50% of the agricultural land (AL) is located above an altitude of 500 m a.s.l. Previous studies have shown that the adopted limit of the average elevation for mountain LFA is too restrictive for the Polish conditions and needs correction. This is particularly clear in the case of agricultural land elevated above sea level. Support for rural development is necessary because the economic importance of agriculture in the Polish mountain and foothill regions is decreasing, and these areas are characterized by a considerably limited land use, under conditions of higher production costs. This is to do with terrain elevation a.s.l. and with the presence of large areas of significant land slopes, making it too to use normal equipment.
Celem pracy była analiza i ustalenie kryteriów przebiegu granicy wysokości, stosowanej w wyznaczaniu obszarów o niekorzystnych warunkach gospodarowania (ONW) w warunkach górskich i podgórskich. Cel ten osiągnięto, weryfikując dane strukturalne o użytkowaniu ziemi w odniesieniu do wysokości n.p.m. Na podstawie zebranych informacji o powierzchni poszczególnych kategorii użytkowania stworzono bazę danych dla 99 gmin górskich w celu oceny użytkowania ziemi. Delimitację obszarów ONW zawiera rozporządzenie Ministra Rolnictwa i Rozwoju Wsi z 2009 r., gdzie wyróżniono tereny o niekorzystnych warunkach gospodarowania „ONW – górskie” wraz z gminami, w których ponad 50% użytków rolnych jest zlokalizowanych powyżej wysokości 500 m n.p.m. Dotychczasowe badania wykazały, że przyjęta graniczna średnia wysokość dla „ONW – górskie” jest zbyt rygorystyczna w warunkach Polski i wymaga korekty. Wsparcie rozwoju wsi jest konieczne, ponieważ znaczenie gospodarcze rolnictwa w rejonach górskich i podgórskich maleje, tereny te charakteryzują się bowiem znacznymi ograniczeniami możliwości użytkowania ziemi i większymi kosztami produkcyjnymi. Ma to związek z wysokością n.p.m. oraz występowaniem na dużej części terenu znacznych spadków, które uniemożliwiają użytkowanie standardowych maszyn.

Opis:: The study of changes in grassland was conducted on the territory of individual counties of the West Pomeranian Voivodship. Based on data collected in the Valorisation of the Agricultural Production Space of Poland and spatial data (an electronic 1:5000 soil and agricultural map) the basic information on the use of agricultural land in the 70s of the 20th century. Changes in use over time were analysed based on data the Statistics Poland (Pol.: Główny Urząd Statystyczny - GUS), General Geographic Database and The Agency for Restructuring and Modernisation of Agriculture Crop Register (Pol.: Agencja Restrukturyzacji i Modernizacji Rolnictwa - ARiMR). The studies showed that in the West Pomeranian Voivodship, a successive decrease in the share of permanent grasslands (0.9%) and arable lands (1.4%) is observed. There is a spatial variation in the share of permanent grassland in the province’s counties, with a distinction between northern and southern counties. The main direction of change in grassland area is arable land, which applies to counties with the highest share of permanent grassland (PG) and counties with a high share of the best soils and forest direction. Land quality was the main factor determining the direction of grassland changes, with the best PG converted to arable land or for investment purposes. In contrast, the weakest were converted to forestry or spontaneously wooded through abandonment. The main reasons for changes in grassland areas in the West Pomeranian Voivodship were: conversion of use to arable land, afforestation of grasslands, land use for urban planning purposes, leaving land fallow and conversion for constructing fishponds.
