Unidade geoambiental é um importante instrumento no auxílio do planejamento e da regulação do uso da terra. Os principais desafios para delimitar unidades geoambientais são isolar, identificar e caracterizar precisamente os atributos ambientais. O objetivo deste trabalho foi delimitar unidades geoambientais na bacia hidrográfica do rio Natuba, numa escala de semidetalhe, a partir da caracterização do meio físico, visando gerar subsídios para o planejamento ambiental da bacia. Foram feitas caracterizações pedológicas, geomorfológicas, geológicas, hidrológicas, climáticas e de uso da terra, a partir de informações da literatura e dados coletados no campo. A caracterização pedológica foi considerada a principal, e a partir dela foram inseridos e analisados os outros atributos físicos. As informações sobre todos os atributos caracterizados foram sobrepostas utilizando o aplicativo Arc gis 9.3, gerando oito unidades geoambientais na bacia. palavras-chave: solos, geologia, drenagem, declividade, uso da terra Delimitation of Geoenvironmental Units in a Watershed from Humid Zone in Pernambuco State ABSTRACT Geoenvironmental unit is an important tool for planning and regulation of land use. The main challenges to delimit geoenvironmental units are to isolate, identify and characterize the environmental attributes accurately. The aim of this work was to determine environmental physical attributes and delimit geoenvironmental units in Natuba river basin, on a semi detail scale, in order to generate information for environmental planning basin. Characterizations were pedological, geomorphological, geological, hydrological, climate and land use attributes, based on information from the literature and data collected in the field. The pedological attribute was considered the main, and from it were included and analyzed the other physical attributes. Data on all the determined attributes was overlapped using the Arc gis 9.3 software. Eight geoenvironmental units were established on the basin. Keywords: soils, geology, drainage, slope, land use

Flood Risk Index (FRI) is the multi-criteria linked with the factors of vulnerability; exposure, susceptibility, and resilience. In order to establish local FRI, crucial local information have to be accumulated. However, under the limitation of land-use data, particular techniques were applied in this study. CA Markov model was used to analyze the past missing land-use data and, also forecast the future land-use of Pakpanang river basin under conditions of plan and without plan. The ratio changes of forest, agriculture, wetland and water, and urban areas were considered. Then, the result of LULC spatial-temporal changes was then applied to Hec-HMS and Hec-Ras , with Arc GIS extension of Hec-GeoHMS and Hec-GeoRas software, in order to evaluate the flood hydrographs and flood severity in three municipalities corresponding to 100-year return period rainfall. Afterward, the FRI of Pakpanang, Chianyai, and Hua-sai, which ranges from 0 to 1, were evaluated by using the modified FRI equations. It was found that sensitivity analysis in the area of forest on flood depth and inundation areas is incoherent. Nevertheless, without land-use planning, the changes in these three cities cause higher flood risk, where Chianyai is the riskiest as the FRIE is 0.58. Further consideration of FRIE and FRIP proportion that reveals the FRI deviation indicates that to reduce flood risk, Chianyai would need the most resources and highest effort comparison to Pakpanang and Hua-sai.

Environmental planning studies are important tools used for the conservation of natural landscapes. The objective of this study was to evaluate the eco-dynamic stability and environmental fragility of the Cabaçal river basin, Mato Grosso State. The methodology of empirical analysis from the environmental fragility proposed by ROSS (1994) was applied, using geo-technologies for mapping the index of relief dissection, soils, land use/land vegetation cover, and climate. Approximately 60% of the area from the basin under study presents unstable eco-dynamic units. The Rio dos Bugres subbasin is the unit with the greatest landscape instability (74.39%). The Rio Branco subbasin has the highest areal percentage of class Strong fragility (20.38%). It is concluded that most of the extension of the Cabaçal River basin presents a high fragility and unstable eco-dynamic units which can compromise the environment in this importante unit of the Upper Paraguay Basin and the Pantanal biome

Sustainable development, biodiversity and landscape diversity should be a key component in nature oriented curricula. The Faculty of Natural Sciences of Comenius University in Bratislava trains specialists in natural and environmental science in Master's degree, in particular in the context of the curricula “Environmental Planning and Management” and “Landscape Protection and Land Use”. The aim of the analysis was to assess the compulsory and elective study subjects of the curricula in question in terms of coverage of themes of sustainable development (SD). The curricula structure and content were analysed on the basis of 14 themes. The results showed that 20 out of the 41 study subjects cover more than 50% of SD themes. The other subjects, more narrowly focused, are also of importance, because they cover key themes such as biodiversity in detail. Graduates’ preparedness for practice and competencies should be sufficient, but it would be appropriate to also focus on the themes in the study subjects in terms of SD indicators.

Erosion Intensity

Land use change in all river basins leads to changes in hydrologic response, soil erosion, and sediment dynamics characteristics. Those changes are often viewed as the main cause of accelerated erosion rates. We studied the impact of land use changes on soil erosion processes in one of the watersheds in Montenegro: the Miocki Potok, using this watershed as a pilot river basin for this area. We simulated responses of soil erosion processes by using a process-oriented soil erosion Intensity of Erosion and Outflow (IntErO) model, with different settings of land use for the years 1970, 1980, 1990, 2000, 2010, and 2020. The model provides fast, effective, and affordable insight into the effects of land use change on soil erosion processes. Testing of the applied procedures was important for the further establishment of watershed management methodologies at the national level, for the other 300 river basins of Montenegro. For the current state of land use, calculated peak discharge for the Miocki Potok was 364 m3 s−1 (2020)–372 m3 s−1 (1970) for the incidence of 100 years, and there is a possibility for large flood waves to appear in the studied basin. Real soil losses, Gyear, were calculated at 13680 m3 year−1 (2020) and specific 333 m3 km−2 year−1 (2020). A Z coefficient value of 0.439 (2020) indicated that the river basin belongs to destruction category III. The strength of the erosion process was medium, and according to the erosion type, it was mixed erosion. According to our analysis, the land use changes in the last 50 years influenced a decrease in the soil erosion intensity for 14% in the Miocki Potok River Basin. Further studies should be focused on the detailed analysis of the land use changes trends with the other river basins at the national level, closely following responses of soil erosion to the changed land use structure, and effects of plant-and-soil interaction on soil erosion and sediment dynamics.

Abstract The present paper focuses on spatial management regulations in order to carry out investment in the field of airport facilities. The construction, upgrades, and maintenance of airports falls within the area of responsibility of local authorities. This task poses a great challenge in terms of organisation and finances. On the one hand, an active airport is a municipal landmark and drives local economic, social and cultural development, and on the other, the scale of investment often exceeds the capabilities of local authorities. The immediate environment of the airport determines its final use and prosperity. The objective of the paper is to review legislation that affects airports and the surrounding communities. The process of urban planning in Lodz and surrounding areas will be presented as a background to the problem of land use management in the vicinity of the airport. This paper seeks to address the following questions: if and how airports have affected urban planning in Lodz, does the land use around the airport prevent the development of Lodz Airport, and how has the situation changed over the time? It can be assumed that as a result of lack of experience, land resources and size of investments on one hand and legislative dissonance and peculiar practices on the other, aviation infrastructure in Lodz is designed to meet temporary needs and is characterised by achieving short-term goals. Cyclical problems are solved in an intermittent manner and involve all the municipal resources, so there’s little left to secure long-term investments.

The paper deals with the syntaxonomy of vegetation on the sandy outcrops in the Pechora (Malozemelskaya and Bolshezemelskaya) tundra. The vegetation was classified using the Brown-Blanke approach. Communities were referred to 3 associations: Arctostaphylo alpini—Empetretum hermaphroditi (Zinserling 1935) Koroleva 1994, Elymo—Festucetum arenariae (Regel 1923) Nordhagen 1955 and Rumici graminifoliae—Festucetum sabulosae ass. nov. Five new variants were suggested within the first association and 2 subassociations and 4 variants within the last one. Syntaxon description and phytocoenological tables are presented. The vegetation on each sandy outcrops represents a complex of communities fragmentary located on the scars area. Subass. inops of ass. Rumici graminifoliae—Festucetum sabulosae is more common in the Ortina river basin and occurs at the bottom of blowing hollows. Syntaxa of ass. Elymo—Festucetum arenariae and var. Festuca rubra of ass. Rumici graminifoliae—Festucetum sabulosae are situated at the mobile sands in the central part, while var. Arctous alpina of ass. Rumici graminifoliae—Festucetum sabulosae occurs on a periphery of out­crops where substratum is stable. The variants inops and typicum of ass. Arctostaphylo alpini—Empetretum hermaphroditi occuring in the Sedujyakha river basin occur mostly in the centre of sandy outcrops, and the other ones can be met on their periphery. Ecological conditions determine poor diversity of syntaxa of the association level. Geographical position (the Sedujyakha river basin belongs to the northern hypoarctic tundras, the Ortina river basin — to the southern hypoarctic ones), geomorphology (in the first site — tops of hills and ridges, in the second one — watershed areas) and area of sandy outcrops (200—3000 m2 for the first and 61000—418000 m2 for the second site respectively) are the reasons for the less diverse communities found in each study site. A great number of variants is conditioned by succession stages of vegetation and instability of the substrates.
