Opis:
Climate change is one of the most critical threats to the human population and other living organisms on Earth. REDD+ is developed as a mechanism to acquire a global fund for addressing climate change, deforestation, and protecting the forest ecosystem while maintaining the livelihood of local communities. As a response to the need for carbon stock measurement at the specific forest and land-use types, this research aimed to estimate the aboveground carbon stock at seven land-use types in KPHP (Forest management unit) Katingan Hulu Central Kalimantan Indonesia. This research was conducted from May to September 2019. The data collected in 91 observation plots included diameter at breast height, total height, and fresh weight of understory vegetation and litter. Using an allometric equation, this research estimated the above-ground carbon stock in trees, understory vegetation, and litter. It was found that AGC varied across different land-use types: secondary peat forest 135.30 Mg C/Ha, secondary forest 212.19 Mg C/Ha, shrub 47.41 Mg C/Ha, oil palm plantation 73.76 Mg C/Ha, rubber plantation 65.56 Mg C/Ha, and forest with rattan 75.98 Mg C/Ha. It was concluded that AGC in KPHP Katingan Hulu varied according to the type of land use system. The forests with less human intervention, such as secondary forests, had higher AGC compared with highly disturbed forests such as shrubs. The findings from this research could help decision-makers to develop the REDD programs to rehabilitate forests and contribute to community development.

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:
Changing coastal zones in Indonesia, such as coral reefs, seagrass, and mangroves, have an impact on tropical ecosystems. Excessive exploitation and sedimentation, in particular, have threatened the mangrove at Segara Anakan Cilacap. In order to evaluate temporal land cover changes and the impact of high siltation on the Segara Anakan lagoon system in Cilacap, Indonesia, a research was conducted. The land cover data from SPOT 4 was available in 2008, and the Sentinel-2A data was available in 2019. The Normalized Difference Vegetation Index (NDVI) was used to enhance the Macro Class with supervised classification utilizing Maximum Likelihood techniques. Mangroves and water bodies declined between 2009 and 2019, whereas settlements and farmland areas increased, according to this study. In the western part of Segara Anakan, extensive siltation altered the biomass, structure, and composition of mangrove vegetation. At high sedimented habitats, Acanthus and Derris dominate, followed by Nypa. The changes in land cover and land use had an impact on socioeconomic factors. Decreases in water bodies and mangrove areas, as well as an increase in farmland, were significantly linked to a shift in society’s livelihoods from fishermen to farmers. The destruction of mangrove habitats in the Segara Anakan has been accelerated by anthropogenic activity and population pressure. Because this sensitive environment is constantly threatened by anthropogenic activity and climate change, effective management of the Segara Anakan Lagoon mangrove ecosystem is important for its long-term viability.

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:
This study concerns the influence of urbanized trend affected on the flood hydrograph in a small catchment in Warsaw. Based on recorded events a selected procedure for simulation rainfall-runoff process has been accepted for flood estimation. The Soil Conservation Services Curve Number method (SCS-CN) and empirical formulae for Nash model parameters, developed by Rao at al. were used to analyze the nine selected events from 2007 to 2009. The analysis confirmed usefulness of the selected procedure, implicated in a home developed computer program, for estimating flood hydrographs as responses of the small urban catchment to heavy rainfall events. Flood hydrographs were estimated for three various stages of land use. The results demonstrate that the peak flood flow would increase over eight times due to urbanisation of the catchment.
Przeanalizowano wpływ zmian zagospodarowania terenu (postępującej urbanizacji) na wzrost przepływów wezbraniowych, wywołanych opadem maksymalnym, o różnym czasie trwania i o prawdopodobieństwie przekroczenia 10%. Ustalone z danych pomiarowych parametry koncepcyjnego modelu opad-odpływ potwierdziły przydatność metody CN-SCS do wyznaczania opadu efektywnego, oraz wzorów Rao, Delleura i Sarmy do wyznaczania parametrów modelu Nasha do transformacji opadu efektywnego w odpływ bezpośredni. Obliczenia wykazały ponadośmiokrotny wzrost przepływów maksymalnych wywołanych opadem o podanej charakterystyce.

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:
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:
In this study, the presence of changes leading towards renaturalization of the fertile deciduous forests has been established. An increase in the proportion of deciduous tree species and herbaceous species from clearings or forest margins also has been noted. The main direction of changes involved increase in humidity, trophic properties and reaction of soil. Improvement in properties of the ground forest, which is associated with an increase in dead organic matter counteracting the negative effect of beech leafs is the main cause of the changes. Ongoing processes should lead to an increase in the tree and undergrowth biodiversity, at the same time causing a decrease in spatial heterogeneity of the deciduous piedmont forest.

Opis:
There are many reasons that the losses caused by extreme weather events are escalating year by year in Hungary. They include Hungary’s geographical characteristics, climate change, river regulation and the expansion of cultivated land. Changes in land use have hugely damaged natural capital, primarily decreasing the area of wetland. Wetlands are multiple-value resources and just one of their functions in the ecosystem is flood regulation. This type of habitat is able to store excess water which can be used in times of drought. At the same time, appropriate land-use (such as increasing the area of wetlands) can help address extreme weather events and increase the amount of natural capital. During the research this paper describes, the social impacts of different kinds of land-use were examined using cost-benefit analysis, contingent valuation and the benefit transfer method. These methods are able to assist with environmentally sustainable decision making as they can be used to show the social preferences for different types of habitats.
Istnieje wiele przyczyn, z powodu których straty powodowane przez ekstremalne warunki pogodowe są na Węgrzech z roku na rok coraz większe. Zaliczyć do nich można uwarunkowania geograficzne Węgier, zmiany klimatyczne, regulacje rzek oraz przekształcanie gruntów na cele uprawne. Zmiany wykorzystania gruntów w ogromnym stopniu przyczyniają się do ubytków w kapitale naturalnym, przede wszystkim zmniejszając powierzchnie terenów podmokłych. Tymczasem są one wielowartościowym zasobem, a jedną z ich funkcji w ekosystemie stanowi regulacja wylewów rzek. Ten rodzaj siedlisk jest w stanie gromadzić nadmiar wody, który z kolei można wykorzystać w trakcie suszy. Jednocześnie odpowiednie gospodarowanie gruntami (np. poprzez zwiększanie powierzchni terenów podmokłych) można stosować w odpowiedzi na ekstremalne warunki pogodowe oraz w celu poprawy kapitału naturalnego. Artykuł przedstawia wyniki badań, ukierunkowanych na określenie społecznego oddziaływania różnych sposobów gospodarowania gruntami za pomocą takich metod badawczych, jak analiza kosztów i korzyści, wycena warunkowa oraz transfer korzyści. Metody te mogą być z powodzeniem stosowane podczas procesów decyzyjnych zrównoważonych środowiskowo, ponieważ są w stanie ukazać społeczne preferencje co do różnych rodzajów siedlisk.

Opis:
The aim of the paper is to examine the scale of the depletion of forest lands in the areas bordering on the capitals of Polish voivodeships. The analysis of the communes around studied urban centres allows for the assessment of the local governments’ spatial development policy with reference to forest lands. The paper shows how local authorities prevent these lands from disappearing and how closely this task is related to the usage of the spatial information instruments such as land use plans (spatial development plans). In the paper the index of the loss of forest land has been used. It estimates the percentage of the forest land that constitutes forest land intended for deforestation in land use plans with reference to the total area of forest land registered in a commune in 2013. Out of the 148 communes that border on capitals of voivodeships only 34 were qualified for the research, namely those with index of forest land depletion higher than its average value for Poland. One of the conclusions of the research is that areas particularly threatened by the loss of forest lands are those that border on Warsaw, Łódź and Lublin.

Opis:
This study contributes to the literature on how to explicitly describe, track, and interpret the structure and dynamics of land systems in borderlands. The shift in land system science analytics from place-based toward larger-scale analysis of interactions and connections in a globalized context provides an opportunity to synthesize the knowledge about borderlands. This paper argues that studies on land system changes in borderlands need to thoroughly link the features of borderland regions with multiple interactions – on either or both sides of a border – rather than simply focusing on shifts within closed national boundaries. Furthermore, this paper provides important insights that can advance existing approaches to track and interpret changes in the land systems of borderlands.
Niniejsze opracowanie przyczynia się do jednoznacznego opisu, śledzenia i interpretacji struktury i dynamiki systemów lądowych na obszarach przygranicznych. Przejście w analizie nauk o systemie lądowym z analizy opartej na miejscu na analizę interakcji i połączeń na większą skalę w zglobalizowanym kontekście daje możliwość nowej syntezy wiedzy na temat pogranicza. W niniejszym artykule wykazuje się, że badania zmian w systemie lądowym na obszarach przygranicznych muszą dokładnie wiązać cechy regionów przygranicznych z wieloma interakcjami – po jednej lub po obu stronach granicy – zamiast koncentrować się wyłącznie na przesunięciach w obrębie zamkniętych granic krajowych. Ponadto niniejszy artykuł zawiera ważne informacje, które mogą usprawnić istniejące podejścia do śledzenia i interpretacji zmian w systemach lądowych pogranicza.

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.

Urbanization directly affects the existing infrastructure, landscape modification, environmental contamination and traffic pollution especially if there is lack of urban planning. Recently, the rapid urban sprawl has resulted in less developed green areas and has devastating environmental consequences. This study was aimed to study the past urban expansion rates and Measure LST from satellite data. The Land use land cover (LULC) maps of years 1996, 2010, 2013, and 2017 were generated using Landsat satellite images. Four main classes i.e. water, urban, bare land and vegetation were identified using unsupervised classification with iterative self-organizing data analysis (isodata) technique. The LST from satellite thermal data can be derived from different procedures:atmospheric, radiometric calibrations and surface emissivity corrections, classification of spatial changeability in land-cover. Different methods and formulas were used in the algorithm that successfully retrieves the land surface temperature to help us study the thermal environment of the ground surface. To verify the algorithm, the land surface temperature and the near-air temperature were compared. The results showed that, From 1996-2017 urban areas increased to about considerable increase of about 48%.few areas of city also shown in reduction in LST from year 1996-2017that actually began their transitional phase from rural to urban LULC.Mean temperature of city increased averagely about 1ºC each year in the month of October. The green and vegetative areas witnessed a decrease in area while higher number of pixels increased in urban class.

Opis:
The aim of this study is to look at the impacts of land use and climate change on extreme runoff regimes in selected catchments of Slovakia, with an emphasis on selected characteristics of hydrological regimes, catchment runoff, and, especially extreme runoff. Changing climate conditions, characterized especially by changes in precipitation, air temperatures, and potential evapotranspiration in future decades, have been predicted by recent outputs of the KNMI and MPI regional climate change models and the A1B emission scenario. The land use changes were characterized by various future land use scenarios. Assuming these scenarios are accurate, the hydrological regime characteristics were simulated by the WetSpa distributed rainfall-runoff model, which was parameterized for the selected river basins with a daily time step until 2100. Changes in the total runoff and its components (the maximum and design discharges), as well as changes in soil moisture and actual evapotranspiration, compared to the current state, confirm the assumption of an increase in the extremes of the hydrological regimes during periods of flood events. The results of the study showed a need for a reevaluation of design discharge values for future designs of water management structures.
