Opis:
Our ecosystem, particularly forest lands, contains huge amounts of carbon storage in the world today. This study estimated the above ground biomass and carbon stock in the green space of Bilbao Spain using remote sensing technology. Landsat ETM+ and OLI satellite images for year 1999, 2009 and 2019 were used to assess its land use land cover (LULC), change detection, spectral indices and model biomass based on linear regression. The result of the LULC showed that there was an increase in forest vegetation by 12.5% from 1999 to 2009 and a further increase by 2.3% in 2019. However, plantation cover had decreased by 3.5% from 1999–2009; while wetlands had also decreased by 9% within the same period. There was, however, an increase in plantation cover from 2009 to 2019 by 2.1% but a further decrease in wetlands of 4.3%. Further results revealed a positive correlation across the three decades between the widely used Normalized Differential Vegetation Index (NDVI) with other spectral indices such as Enhance Vegetation Index (EVI) and Normalized Differential Moisture Index (NDMI) for biomass were: for 1999 EVI (R2 = 0.1826), NDMI (R2 = 0.0117), for 2009 EVI (R2 = 0.2192), NDMI (R2 = 0.3322), for 2019 EVI (R2 = 0.1258), NDMI (R2 = 0.8148). A reduction in the total carbon stock from 14,221.94 megatons in 1999 to 10,342.44 megatons 2019 was observed. This study concluded that there has been a reduction in the amount of carbon which the Biscay Forest can sequester.

Opis:
Coal is one of the most mining commodities to date, especially to supply both national and international energy needs. Coal mining activities that are not well managed will have an impact on the occurrence of environmental damage. The present study was undertaken to analyze the process of humaninduced landscape transformation in the coal mines affected areas of Cam Pha, northeast Vietnam by interpreting temporal remote sensing data and using Geographic Information System. This experiment revealed that most of the study area was dominated by forest in all the time sequence period. The forest cover has decreased about 21.3%, meanwhile having nine fold increase in mining area from 1990 to 2020. The forest area lost during the study period was 7983.45 ha due to land cover conversion into mining area. The mining activities were also detrimental to the bare land and water body cover. The results of this study are expected to be used to support government efforts and mining managers in post-mining coal activities.

Opis:
Historical and archival sources are of cardinal importance in landscape research addressing the processes and course of landscape changes in European regions. The Franziscean cadastre from the 19th century is among the most widely used historical sources in Central Europe. We identified 1440 records, finally providing 104 articles reporting the use of the Franziscean cadastre for in-depth analyses in order to identify (i) the practice of the cadastral data processing, (ii) purpose and spatial extent of the study, (iii) use of complementary sources and (iv) particular land use/land cover classes under study. We have found the increasing attention towards the Franziscean cadastre as a source for landscape research reflected by the doubling number of records in the past decade with majority of the case studies located in Czechia (79), followed by Austria (9) and Italy (3). We have identified the trends in the use in landscape trajectory research and application to hydrology, agriculture and forestry. As regards the data processing, several  issues connected with the methodology or design of the records were found (e.g. geographic information system processing description and data source specification). We further problematize the suitability of the supplementary data used and conclude our review with a set of recommendations to contribute to the discussion on the methodology of landscape reconstruction with historical datasets.

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:
This study presents the information on the dynamics of changes in land use/land cover (LULC) spatially and temporally related to the causes of flooding in the study area. The dynamics of LULC changes have been derived based on the classification of Landsat imagery for the period between 1990 and 2016. Terrain surface classification (TSC) was proposed as a micro-landform classification approach in this study to create flood hazard assessment and mapping that was produced based on the integration of TSC with a probability map for flood inundation, and flood depth information derived from field observation. TSC as the micro-landform classification approach was derived from SRTM30 DEM data. Multi-temporal Sentinel-1 data were used to construct a pattern of historical inundation or past flooding in the study area and  also to produce the flood probability map. The results of the study indicate that the proposed flood hazard mapping (FHM) from the TSC as a micro-landform classification approach has the same pattern with the results of the integration of historical inundation or previous floods, as well as field investigations in the study area. This research will remain an important benchmark for planners, policymakers and  researchers regarding spatial planning in the study area. In addition, the results can provide important input for sustainable land use plans and strategies for mitigating flood hazards.

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:
Many countries, including Indonesia, face severe water scarcity and groundwater depletion. Monitoring and evaluation of water resources need to be done. In addition, it is also necessary to improve the method of calculating water, which was initially based on a biophysical approach, replaced by a socio-ecological approach. Water yields were estimated using the Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) model. The Ordinary Least Square (OLS) and geographic weighted regression (GWR) methods were used to identify and analyze socio-ecological variables for changes in water yields. The purpose of this study was: (1) to analyze the spatial and temporal changes in water yield from 2000 to 2018 in the Citarum River Basin Unit (Citarum RBU) using the InVEST model, and (2) to identify socio-ecological variables as driving factors for changes in water yields using the OLS and GWR methods. The findings revealed the overall annual water yield decreased from 16.64 billion m3 year-1 in the year 2000 to 12.16 billion m3 year-1 in 2018; it was about 4.48 billion m3 (26.91%). The socio-ecological variables in water yields in the Citarum RBU show that climate and socio-economic characteristics contributed 6% and 44%, respectively. Land use/Land cover (LU/LC) and land configuration contribution fell by 20% and 40%, respectively.The main factors underlying the recent changes in water yields include average rainfall, pure dry agriculture, and bare land at 28.53%, 27.73%, and 15.08% for the biophysical model, while 30.28%, 23.77%, and 10.24% for the socio-ecological model, respectively. However, the social-ecological model demonstrated an increase in the contribution rate of climate and socio-economic factors and vice versa for the land use and landscape contribution rate. This circumstance demonstrates that the socio-ecological model is more comprehensive than the biophysical one for evaluating water scarcity.

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.

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:
Hydrological modelling and processes using modern hydrological models like SCS Curve Number, HCS, HSPF (Hydrologic Simulation Package-Fortran) and kinematic wave models are widely used nowadays in various researches. But using these modelling in drawing the attention of urban planners for challenges and multiple interactions in heterogeneous urban catchments and water systems is still a shortcoming in water sensitive, planning principle. The art of urban planning and technical implementation using behavioural changes in water responses to urban catchments is the need of present urban planning. The complexities of effects and behavioural changes in the water system or urban catchments and incomplete knowledge of these interactions result in failures of sustainable urban developments. Urban planning needs water sensitive methodology to synchronize soil, water and land cover operational with the population over it. The paper reviews the water sensitive urban planning considering the role of soil in urban planning for water and lands correlations, with the purpose of identifying current limitations and opportunities for future urban planning. Data availability and simplified methods are still a strong limitation for urban planners. Therefore, urban hydrology is often simplified either as a study of surface runoff over impervious surfaces or hydraulics of piped systems. Hence the paper provides approach and universal solution to forecast the behaviour of urban catchment for urbanization in terms of natural land-water cycles and its application in planning existing or new urban catchments. The methodology consists of observing Urban watershed catchment areas with different soil groups and built-up induction over them. A detailed study of water levels in hydrological wells and runoff pattern for the period of 40 years have provided a linear correlation of soil, roughness, land cover, infiltration, ground water and built upon the basis of soil behaviours. These correlations conclude to make regression equations as the blueprint for future urban planning norms to be followed by the planners, engineers, and hydrologists for planning.
Modelowanie hydrologiczne za pomocą takich modeli, jak SCS Curve Number, HCS czy Pakiet Hydrologicznych Symulacji Fortran (HSPF) oraz kinematyczne modele falowe są obecnie powszechnie stosowane w różnych badaniach. Nadal jednak brak takiego modelowania w pracy urbanistów stojących wobec wyzwań, stawianych przez wielorakie oddziaływania heterogennych zlewni miejskich z systemami wodnymi. Sztuka planowania urbanistycznego i wdrożeń technicznych korzystających ze zmian reakcji wody na zlewnie miejskie jest potrzebą obecnego planowania miast. Złożoność efektów i zmiany w systemach wodnych lub miejskich zlewniach oraz niepełna znajomość tych interakcji skutkuje niepowodzeniami w zrównoważonym rozwoju miast. Planowanie miast wymaga metodologii wrażliwej na kwestie wodne, aby operacyjnie powiązać glebę, wodę i pokrycie gruntów z populacją ludzką. W pracy dokonano przeglądu planowania urbanistycznego wrażliwego na kwestie wodne z uwzględnieniem roli gleby w planowaniu relacji wody z lądem celem zidentyfikowania bieżących ograniczeń i możliwości przyszłego planowania. Dostępność danych i uproszczone metody to nadal silne ograniczenie urbanistów. Dlatego hydrologia miasta bywa często upraszczana do badania spływów po nieprzepuszczalnych powierzchniach lub do hydrauliki systemów wodociągowych. Niniejsza praca prezentuje sposób podejścia i uniwersalne rozwiązanie służące prognozowaniu zachowania zlewni miejskiej w reakcji na urbanizację w odniesieniu do naturalnej relacji ląd–woda i ich zastosowanie w planowaniu istniejących bądź nowych zlewni miejskich. Metodologia polega na obserwacji 19 zlewni miejskich o różnych typach gleb i zabudowy. Szczegółowe analizy poziomów wody w studzienkach hydrologicznych i schematu spływów wody w okresie 40 lat dostarczyły danych do wyprowadzenia liniowej korelacji między rodzajem gleby, szorstkością podłoża, pokryciem powierzchni ziemi, infiltracją, wodami podziemnymi, wszystkie powiązane z właściwościami gleb. Te korelacje umożliwiły ustalenie równań regresji stanowiących schemat dla przyszłych norm planowania urbanistycznego do wykorzystania przez planistów, inżynierów i hydrologów.

Opis:
W artykule przedstawiono stan zagospodarowania i formy przedsiębiorczej działalności człowieka w dwóch zlewniach położonych w Beskidzie Niskim. Przesłanką do podjęcia badań było często opisywane zjawisko zaniku działalności gospodarczej w obszarach górskich, szczególnie w sektorze rolnictwa. Jednym z celów było sprawdzenie, czy we wskazanych zlewniach również wystąpiły zmiany i jaki był ich kierunek, także w perspektywie historycznej. Podano też czynniki, które mogły mieć wpływ na ukształtowanie się postaw przedsiębiorczych w tamtym rejonie. Przykłady zawarte w artykule mogą być przydatne w nauczaniu podstaw przedsiębiorczości w szkole średniej. Dane historyczne pozyskano za pomocą kwerendy literatury przedmiotu. Informacje o liczbie ludności oraz gospodarstw i przedsiębiorstw lokalnych zebrano w urzędzie gminy Dukla, jej sołectwach oraz za pomocą wywiadów środowiskowych. Zmiany pokrycia terenu określono na podstawie dwóch materiałów źródłowych (z 1978 i 2015 r.) opracowanych w GIS. Pomimo znaczących przemian politycznych, ekonomicznych i społecznych (wymiana ludności, przerwane nagle funkcjonowanie Państwowych Gospodarstw Rolnych - PGR-ów, wyludnianie się wsi) na terenie obu zlewni funkcjonują zarówno gospodarstwa rolne, jak i agroturystyczne, dzięki czemu obecna struktura pokrycia terenu jest podobna do stwierdzonej w latach 70. XX w. Wprowadzenie dopłat unijnych do rolnictwa zachęciło przedsiębiorców do przejmowania państwowych gruntów rolnych i ich zagospodarowania. Przykład ten warto omówić na lekcji przedsiębiorczości.
The article presents the state of development and forms of entrepreneurship in two catchments located in the Beskid Niski mountain range. The often described process of the disappearance of economic activity in mountain areas, especially agriculture, was the reason for undertaking the research. The purpose was to check these changes and their directions in the catchment areas, also in a historical perspective. Factors that could have influenced the formation of entrepreneurial attitudes were given. The examples in the article can be useful in delivering topics during entrepreneurship classes in high school. Historical data was obtained through literature query. Information about the population, farms and local enterprises was collected at the Dukla commune office and village councils and through interviews. Changes in land cover were determined in GIS on the basis of two source materials (from 1978 and 2015). Despite significant political, economic and social changes (population exchange, sudden dissolution of State Agricultural Farms, depopulation of villages), both agricultural and agro-tourist farms operate in the catchments. The current land cover structure is similar to the 1970s. The EU subsidies for agriculture has encouraged entrepreneurs to take over state-owned agricultural land and their development. This case is worth discussing during entrepreneurship classes.

Opis:
Land use/land cover changes (LULCC) at Adei watershed (Ethiopia) over a period of 23 years (1986–2009) has been analysed from LANDSAT imagery and ancillary data. The patterns (magnitude and direction) of LULCC were quantified and the final land use/land cover maps were produced after a supervised classification with appropriate post-processing. Image analysis results revealed that the study area has undergone substantial LULCC, primarily a shift from natural cover into managed agro-systems, which is apparently attributed to the increasing both human and livestock pressure. Over the 23 years, the aerial coverage of forest and grass lands declined by 8.5% and 4.3%, respectively. On the other hand, agricultural and shrub lands expanded by 9.1% and 3.7%, respectively. This shows that most of the previously covered by forest and grass lands are mostly shifted to the rapidly expanding farm land use classes. The findings of this study suggested that the rate of LULCC over the study period, particularly deforestation due to the expansion of farmland need to be given due attention to maintain the stability and sustainability of the ecosystem.
Zmiany użytkowania i sposobu pokrycia terenu w zlewni Adei (Etiopia) analizowano w ciągu 23 lat (1986–2009) z użyciem obrazów LANDSAT i dodatkowych danych. Oceniono ilościowo schemat zmian (wielkość i kierunek) oraz wykonano mapy użytkowania i pokrycia terenu po odpowiednim przetworzeniu danych. Analiza obrazów ujawniła, że badany obszar podlegał znaczącym zmianom – głównie od naturalnego pokrycia do gospodarczych agrosystemów, co wynikało z rosnącej presji ze strony człowieka i zwierząt gospodarskich. W ciągu 23 lat powierzchnie leśne i trawiaste zmalały odpowiednio o 8,5 i 4,3%, a powierzchnie użytkowane rolniczo i tereny zakrzaczone powiększyły się odpowiednio o 9,1 i 3,7%. Oznacza to, że tereny uprzednio zajmowane przez lasy i systemy trawiaste zostały zajęte przez tereny rolnicze. Przeprowadzone badania sugerują, że należy zwrócić szczególną uwagę na szybkie zmiany pokrycia powierzchni terenu, aby utrzymać stabilność i trwałość ekosystemu.

Opis:
This study focuses on the problem of mapping impervious surfaces in urban areas and aims to use remote sensing data and orthophotos to accurately classify and map these surfaces. Impervious surface indices and green space assessments are widely used in land use and urban planning to evaluate the urban environment. Local governments also rely on impervious surface mapping to calculate stormwater fees and effectively manage stormwater runoff. However, accurately determining the size of impervious surfaces is a significant challenge. This study proposes the use of the Support Vector Machines (SVM) method, a pattern recognition approach that is increasingly used in solving engineering problems, to classify impervious surfaces. The research results demonstrate the effectiveness of the SVM method in accurately estimating impervious surfaces, as evidenced by a high overall accuracy of over 90% (indicated by the Cohen’s Kappa coefficient). A case study of the “Parkowo-Leśne” housing estate in Warsaw, which covers an area of 200,000 m², shows the successful application of the method. In practice, the remote sensing imagery and SVM method allowed accurate calculation of the area of the surface classes studied. The permeable surface represented about 67.4% of the total complex and the impervious surface corresponded to the remaining 32.6%. These results have implications for stormwater management, pollutant control, flood control, emergency management, and the establishment of stormwater fees for individual properties. The use of remote sensing data and the SVM method provides a valuable approach for mapping impervious surfaces and improving urban land use management.
Niniejsze badanie koncentruje się na problemie wyznaczania powierzchni nieprzepuszczalnych na obszarach miejskich i ma na celu wykorzystanie danych teledetekcyjnych i ortofotomap do dokładnej klasyfikacji i wizualizacji tych powierzchni. Wskaźniki powierzchni nieprzepuszczalnych i oceny terenów zielonych są szeroko stosowane w planowaniu przestrzennym i urbanistycznym do oceny środowiska miejskiego. Władze lokalne polegają również na oszacowaniu wielkości powierzchni nieprzepuszczalnych w celu obliczania opłat za wodę deszczową i skutecznego zarządzania odpływem wody deszczowej. Jednak dokładne określenie wielkości nieprzepuszczalnych powierzchni jest poważnym wyzwaniem. W niniejszym badaniu zaproponowano wykorzystanie metody Support Vector Machines (SVM), podejścia opartego na rozpoznawaniu wzorców, które jest coraz częściej stosowane w rozwiązywaniu problemów inżynieryjnych, do klasyfikacji powierzchni nieprzepuszczalnych. Wyniki badań pokazują skuteczność metody SVM w dokładnym szacowaniu powierzchni nieprzepuszczalnych, o czym świadczy wysoka ogólna precyzja wynosząca ponad 90% ( na co wskazuje współczynnik Kappa Cohena). Studium przypadku osiedla „Parkowo-Leśne” w Warszawie o powierzchni 200 000 m² pokazuje skuteczne zastosowanie metody. Wyniki wskazują, że powierzchnie przepuszczalne stanowiły około 67,4% całego kompleksu, podczas gdy powierzchnie nieprzepuszczalne stanowiły pozostałe 32,6%. Wyniki te mogą mieć wpływ na zarządzanie wodami opadowymi, kontrolę zanieczyszczeń, zapobieganie powodziom, zarządzanie kryzysowe i ustalanie opłat za wodę opadową dla poszczególnych nieruchomości. Wykorzystanie danych teledetekcyjnych i metody SVM zapewnia cenne podejście do wizualizacji powierzchni nieprzepuszczalnych i poprawy zarządzania użytkowaniem gruntów miejskich.

Opis:
The real estate cadastre is the primary source of information on land use. It re cords information related to the division of land into types based on the actual way of land use or development. The distinguished types of land use depend on many geographical factors, as well as historical and economic conditions. The study presents a comparison of the detail of land use classification registered in the real estate cadastre in areas functionally related to the urban areas of 9 European countries: Austria, Bulgaria, the Czech Republic, Estonia, Spain, Lithuania, Luxembourg, Germany and Poland. The research concerned the determination of the degree to which the classification of land use in urbanized areas is detailed, whether the studied European countries are characterized by the same number of distinguished classes of ob jects at different levels of detail, and what percentage are the distinguished classes of land use objects in urbanized areas in relation to all of the distinguished classes of objects land use at different levels of detail of classification. The study used legal acts regulating land use issues which have been made available in national languages by government institutions.

The article deals with the research on the quantitative classification of land use, which directly affects the amount of land use data collected in the real estate cadastre. For the purpose of this article, the cadastral systems of seven European countries – Austria, Bulgaria, Estonia, Spain, Lithuania, Germany and Poland – have been examined, taking into account how detailed is the classification in agricultural and forest areas. The research covered the provisions of legal acts applicable in the researched seven European countries and made available in national languages by the government bodies. The article asks the following three questions: 1) whether the researched countries adopted the same approach to isolating classes of items related to agricultural and forest areas; 2) whether the researched countries feature the same number of classes of items recorded at various levels of detail; 3) what is the percentage of the distinguished item classes of land uses in the agricultural and forest areas in relation to all of the distinguished item classes at all the levels of detail. The conducted research can be used as a material supporting works consisting of the modernization of the functioning of land registration in the real estate cadastre in Poland.

Opis:
Over the years, Cameron Highlands have witnessed extensive land-use and land-cover (LULC) changes due to the massive agricultural and urbanization activities. This significantly contributed to the erosion problems in the area. Rainfall erosivity that measures the aggressiveness of raindrop in triggering soil erosion is one of its major components that could be influenced by the LULC changes in watersheds. However, the research relating to the LULC changes with the erosivity especially in the complex landscape is scarce. Hence, this study applies geographic information system (GIS) and remote sensing techniques to assess the LULC changes and their influence on the rainfall erosivity distribution in mountainous watershed of Cameron Highlands. Four Landsat images and the rainfall data from the period of thirty years were analysed for the development of LULC and erosivity maps respectively in ArcGIS environment. The study showed that the study area experienced immense land-use changes especially in agriculture and urbanization which affected the erosivity distribution. The LULC change for agriculture increased linearly in the last 30 years from 7.9% in 1986 to almost 16.4% in 2016. The results showed that urban development increased from 5.1% in 1986 to 11.4% in 2016. The increasing urbanization trend was targeted to meet up with tourism requirement in Cameron Highlands. However, forest class declined tremendously due to the exploration of land for agriculture practice and other various types of development. Watershed managers and other stakeholders should find this study beneficial in tackling erosion and its associated ecological challenges.

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:
In order to analyze the impact of land use and land cover change on land surface temperature (LST), remote sensing is the most appropriate tool. Land use/cover change has been confirmed to have a significant impact on climate through various aspects that modulate LST and precipitation. However, there are no studies which illustrate this link in the Fez-Meknes region using satellite observations. Thus, the aim of this study was to monitor LST as a function of the land use change in the Saïss plain. In the study, 12 Landsat images of the year 2019 (one image per month) were used to represent the variation of LST during the year, and 2 images per year in 1988, 1999 and 2009 to study the interannual variation in LST. The mapping results showed that the land use/cover in the region has undergone a significant evolution; an increase in the arboriculture and urbanized areas to detriment of arable lands and rangelands. On the basis of statistical analyses, LST varies during the phases of plant growth in all seasons and that it is diversified due to the positional influence of land use type. The relationship between LST and NDVI shows a negative correlation (LST decreases when NDVI increases). This explains the increase in LST in rangelands and arable land, while it decreases in irrigated crops and arboriculture.

The key objective of the study is to analyse structural characteristics of the landscape from the viewpoint of the structure’s durability, characteristics and speed of change. The research focused on the area surrounding Płock. In the analysed period (1987-2010) slight changes were detected with regard to the land cover, though they were significant in terms of the natural environment. No single dominant process determining land cover change was identified. Fluctuations prevailed (producing a slightly different picture in each microregion), with a fixed pattern maintained. Distribution, shape and spatial location of land cover types are only partly determined by land lie and habitat quality. Fragmentation of the terrain is relatively high, which reflects intense land use, at the same time indicating opportunities to preserve the wildlife and vegetation typical for agrocenoses.

Opis:
Many cities in developing countries are experiencing ecosystem modification and change. Today, about 10 million hectares of the world’s forest cover have been converted to other land uses. In Nigeria, there is an estimated increase of 8.75 million ha of cropland and decrease of about 1.71 million ha of forest cover between 1995 to 2020, indicating that Nigeria has been undergoing a wide range of land use and land cover changes. This paper analyses the changes in land use/cover in Ila Orangun, Southwestern, Nigeria from 1986 to 2018, with a view to providing adequate information on the pattern and trend of land use and land cover changes for proper monitoring and effective planning. The study utilized satellite images from Landsat 1986, 2002 and 2018. Remote sensing and Geographical Information System techniques as well as supervised image classification method were used to assess the magnitude of changes in the city over the study period. The results show that 26.36% of forest cover and 44.48% of waterbody were lost between the period of 1986 and 2018. There was a rapid increase in crop land by 365.7% and gradual increase in built-up areas by 103.85% at an annual rate of 3.25%. Forest was the only land cover type that recorded a constant reduction in areal extent. The study concluded that the changes in land use and land cover is a result of anthropogenic activities in the study area.

Opis:
The basin of the Służewiecki Stream, hydrologically uncontrolled, is urbanised, but it has a mosaic-like character, consisting of urban and agricultural land use. This is shown by the graph of the basin and its subcatchments that takes into account the changes of the runoff coefficient in its subcatchments. The land cover changes in 1993–2002 and the forecast for the years until 2012, together with the calculated rainfall hyetograph are input elements to the rainfall-runoff model. The isochrone method with the Kirpich equation constitute the transforming function, and the runoff hyetographs are the output elements from the system. The paper presents also practical problems occurring in the implementation of the recommendations of the local spatial plan as well as consequences resulting from disregarding the recommendations.
Niekontrolowana hydrologicznie zlewnia Potoku Służewieckiego o powierzchni zlewni wynoszącej 55 km2 jest w 51% zurbanizowana. Charakteryzuje się nadal mozaikową strukturą użytkowania miejskiego i rolniczego. Obrazuje to wykres trójkątny rozwinięcia zlewni (dopływy prawe i lewe) uwzględniający zmiany współczynnika odpływu w zlewniach cząstkowych. Zmiany użytkowania w latach 1993–2002 i ich prognoza do 2012 roku (z planu zagospodarowania przestrzennego) wraz z obliczonym metodą Bogdanowicz (1998) hietogramem opadu są elementami wejścia do modelu opad-odpływ. Metoda izochron połączona ze wzorem Kirpicha jest funkcją transformującą, a hydrogramy odpływu są elementami wyjścia z systemu. Zmiany użytkowania terenu w latach 1993–2012 obejmą 10% powierzchni zlewni. Spowoduje to ok. 25% wzrost przepływu maksymalnego wywołanego opadem trwającym, zarówno 3 godziny (14–18 m3/s), jak i 8 godzin (16–20 m3/s).

Opis:
Land surface temperature (LST) estimation is a crucial topic for many applications related to climate, land cover, and hydrology. In this research, LST estimation and monitoring of the main part of Al-Anbar Governorate in Iraq is presented using Landsat imagery from five years (2005, 2010, 2015, 2016 and 2020). Images of the years 2005 and 2010 were captured by Landsat 5 (TM) and the others were captured by Landsat 8 (OLI/TIRS). The Single Channel Algorithm was applied to retrieve the LST from Landsat 5 and Landsat 8 images. Moreover, the land use/land cover (LULC) maps were developed for the five years using the maximum likelihood classifier. The difference in the LST and normalized difference vegetation index (NDVI) values over this period was observed due to the changes in LULC. Finally, a regression analysis was conducted to model the relationship between the LST and NDVI. The results showed that the highest LST of the study area was recorded in 2016 (min = 21.1°C, max = 53.2°C and mean = 40.8°C). This was attributed to the fact that many people were displaced and had left their agricultural fields. Therefore, thousands of hectares of land which had previously been green land became desertified. This conclusion was supported by comparing the agricultural land areas registered throughout the presented years. The polynomial regression analysis of LST and NDVI revealed a better coefficient of determination (R2) than the linear regression analysis with an average R2 of 0.423.

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.

Timely and accurate detection of land use/land cover (LULC) change is important for the macro and micro level sustainable development of any region. For this purpose, geospatial techniques are the best tool for change analysis as they supply timely, cheaper, precise and up to date information. This paper examines the spatial temporal change trend in LULC in the case of Central Haryana. Landsat 2, 3, 5, 7 and 8 images for the years 1975–2020 for pre and post monsoon periods were analyzed for the study. Radiometric correction was performed to derive better information. ArcGIS 10.2 and ENVI 5.3 are used for thematic layout and thematic change preparation. An unsupervised classification using ERDAS IMAGINE 2015 has also been done to classify study area in eight classes. The year 1975 is considered as the base year for change detection analysis. Results showed an increasing trend for the land use classes of built up, water body, and agricultural land without waterlogging in the pre and post monsoon periods between 1975 and 2020. Remaining land use classes of agriculture with waterlogging, open waterlogged area, vegetation and fallow land/sand dunes decreased during the same period. Increased human activities have changed the LULC in the region and have had a great impact on its sustainable regional development.

The aim of the paper is to present automated methods of discrimination of urban development forms using object-oriented classification in high-resolution images taken by the Ikonos satellite. The object-oriented classification makes possible to describe individual classes using not only the spectral reflection values but also the shapes, textures and topology of objects. The classification process as such is based on the theory of fuzzy sets. The research covered an area of 25 km,., situated in central Warsaw. As a result of object-oriented classification, five classes of development typical of large cities were distinguished and described.
