Didėjant urbanizacijos mastams, būtina akcentuoti darnų miestų vystymąsi. Dažniausiai literatūroje nagrinėjami ekologiško ir kompaktiško miestų modeliai. Analizė atskleidžia, jog pagrindiniai jų principai yra mišrios paskirties žemės naudojimas, išvystytas visuomeninis transportas bei dviračių takai, didelis tankumas, viešųjų erdvių prieinamumas, gamtos resursų išsaugojimas, ekonominis, socialinis ir ekologinis stabilumas. Baigiamajame darbe nagrinėjami šie du miestų modeliai, socialiniai veiksniai bei nurodoma monitoringo svarba planuojant miesto plėtros tendencijas. Elektrėnų savivaldybės pavyzdžiu išskiriami situacijos vertinimo indikatoriai, naudojami bendrajame savivaldybės plane. Baigiamajame darbe išanalizuoti pagrindiniai principai ir išskirti pagrindiniai subalansuotos plėtros įvertinimo kriterijai, bei nustatyta, kad galima išsami miesto subalansuotumo analizė kombinuojant išskirtus kriterijus. / With increasing the scale of urbanization, it is necessary to focus on sustainable development of the city. The ecological and compact models of the city are common issue in the literature. Main principles of these models are mixed land use, good quality of public transport and opportunity for bicycling, high density, access of public spaces, and conservation of natural resources, economical, ecological and social stability. There are distinguished indicators of state evaluation of Elektrenai municipality as an example. The article examines two urban models, social factors and the importance of monitoring in the urban planning process. In the article, basic principles are analyzed and main sustainable development evaluation criteria are emphasized.

This report aims to answer the question “What is the relationship between adopting a landscape conservation approach and human well-being?” through a case study of the Santa Cruz Mountains Stewardship Network. The Network is a collective that involves a variety of stakeholders that belong to a multidimensional scale and focuses on achieving a wide spectrum of goals. This research looks at the landscape conservation approach, which the Network uses, through the lens of strategic sustainable development by taking a systems perspective. The eight sustainability principles, which are used for the analysis, function as system boundaries for sustainability to aim towards human well-being. The environmental sphere is connected with the social sphere and make up the socio-ecological system and should not be considered separately. This research aims to make this connection clearer to compliment the lack of knowledge on this topic. The main conclusion is that by operating within the 8SPs and using a landscape conservation approach, organizations can contribute directly or indirectly to human well-being and the health of ecosystems. Some of the benefits for humans are an increase in physical and mental health and having the opportunity to find meaning by being out in nature.

Bahir Dar is one of the rapidly growing Ethiopian cities characterized by the rise of informal settlements. The expansion of spontaneous neighbourhoods in Bahir Dar is, among other things, conditioned by land management policies and practices. Thus, the intention of this research was to explore the influences of land management on the prevalence of informal settlements in Bahir Dar city, Ethiopia. So as to meet the study targets this research employed mixed method approach, and the data were gathered from various sources by applying different methods. The quantitative data was drawn from 156 random samples through household surveys. It was collected from four FGDs, interview of eight community elders, sub-cities and municipality officials and code enforcement professionals. Furthermore, case studies, published and unpublished documents, photographs, and satellite images were used to enrich the analysis. To analyse quantitative data, SPSS statistical software was used to extract descriptive statistics, to test hypotheses and to draw tables and various types of graphs. Content analysis was employed to analyse qualitative data. It was found that expansion of informal settlements in Bahir Dar was caused, among others, by Poverty of inhabitants, rural-urban migration, limited capacity of the city to deliver basic services, low housing supply and high housing demand, and limitations in land lease laws, as well deficiency of essential amenities like water, sanitation and electricity. The influences of land management policies and practices that resulted to prevalence of informal settlements were found to be the subjective implementation of housing and land leasing policies, harsh government farm expropriation and very low compensation payments, weak governance practices in land administration, frequent demolishing of houses and precarious security of tenure. Even though informal settlements help to address the housing shortage in the city and contribute to environmental management in some areas of the city, it is largely intimidating environmental management, deteriorating the livelihoods and thus brought about the unsustainable city development. In order to address the challenges of informal settlements, it was suggested that legal framework to formalize informal settlements, develop an effective and efficient land administration system, improving good governance in land administration, establish land and housing policies favouring low-income population, and bring about attitude change favourable to urban development are essential. / Environmental Sciences / D.

Die weltweite Bevölkerungszunahme, sich ändernde Ernährungsgewohnheiten, und die Nachfrage nach Bioenergie erfordern eine Erhöhung der landwirtschaftlichen Produktion. Die Intensivierung bestehender landwirtschaftlicher Flächen ist hierbei eine mögliche Option. Allerdings verstehen wir nur wenig von den räumlichen Mustern der landwirtschaftlichen Nutzungsintensität, da adäquate Datensätze fehlen. Europa ist eine beispielhafte Region, in der eine Intensivierung als auch ein Rückgang der Landnutzung stattfindet. Ziel dieser Dissertation war es Methoden zu entwickeln, die MODIS NDVI Zeitreihen und statistische Daten kombinieren und eine europaweite Kartierung der landwirtschaftlichen Nutzungsintensität ermöglichen. Für eine Einschätzung der landwirtschaftlichen Nutzungsintensität wurden eine Reihe von Intensitätsindikatoren entwickelt und kartiert. Die resultierenden Karten zeigen eine hohe Landnutzungsintensität in West- und Zentraleuropa und dem Mittelmeerraum, gekennzeichnet durch Mehrfachernten und langen Anbauzeiten. Gebiete mit niedriger Intensität lagen in Osteuropa, in Gebirgsregionen sowie in der Extremadura in Spanien, wo Brachland und die Aufgabe von Agrarflächen häufig sind. Die Aufgabe von Agrarflächen ist ein aktueller Prozess der Landnutzungsveränderung in Osteuropa, während die gleichzeitige Rekultivierung ehemaliger Agrarflächen ebenfalls umfassend ist. Diese räumlichen Muster lassen sich mit unterschiedlichen Agrarumweltbedingungen begründen aber auch mit sozioökonomischen Veränderungen wie die Restrukturierung des osteuropäischen Agrarsektors nach 1989 oder die Marginalisierung landwirtschaftlicher Flächen insbesondere in Gebirgsregionen. Die entstandenen Karten belegen das Potential von MODIS NDVI Zeitreihen, komplexe Phänomene landwirtschaftlicher Nutzungsintensität zu erfassen. Diese könnten genutzt werden um Umweltfolgen der landwirtschaftlichen Produktion zu bewerten oder Zielregionen für eine nachhaltige Intensivierung zu identifizieren. / Global population growth, changing diets, and the demand of bioenergy require an increase in agricultural production. Intensifying agricultural production is one pathway to meet increasing demands. However, our understanding of spatial patterns of agricultural land use remains weak since adequate data sets are lacking. Europe is as a prime example for a region that is undergoing both, intensification as well as decreasing agricultural land use. The goal of this doctoral thesis was to develop methodologies that combine MODIS NDVI time series and agricultural statistics to map spatial patterns of land-use intensity across Europe. To assess land-use intensity, a wide range of intensity indicators were mapped. The resulting maps revealed high-intensity areas in Western and Central Europe and the Mediterranean region, characterized by multi-harvests and long crop duration. Low-intensity areas are mostly located in Eastern Europe, in mountain regions and the Extremadura in Spain, where fallow and abandonment land are widespread. Agricultural abandonment is an ongoing land-use change process in Eastern Europe. At the same time, recultivation of formerly abandoned land is widespread as well. These spatial patterns are the result of agro-environmental conditions but also of changes in socio-economic conditions such as the restructuring of the agricultural sector in eastern European countries after 1989, or the marginalization of farmland especially in mountain regions. The resulting maps show the potential of MODIS time series to assess the complex phenomenon of land-use intensity. They may form a basis to assess the environmental outcomes of agricultural production and to identify target regions for sustainable intensification.

In the Brazilian case, and with regard to territorial public policies, such as urban planning and urban and regional planning,discussions generally restricted to the field of administrative law, predominantly instrumental in character, whose effects invariably limited to specific actions, topical and devoid of virtue to reach the root causes of urban issue. And more. They reappear with the contemporary environmental crisis. Another factor that affects decisively reflection and proposition urban instruments developed with a view to solving the urban problems is the application of the concept applied to management of public affairs. Originally conceived in the context of organizations, employment management, to migrate to public administration, reduces the understanding of the political dimension to the city's plan merely negotiated territorial management. This also proves insufficient, which will be addressed through a particularly significant that relates environmental and urban issues: the National Policy on Solid Waste. / Visando contribuir nos debates que envolvem o equacionamento da problem?tica urbanoambiental, a disserta??o parte do pressuposto de que certas abordagens, por se bastarem ?s an?lises conjunturais, s?o impotentes para lidar com a natureza estrutural que as revestem. No caso brasileiro, e no que diz respeito ?s pol?ticas p?blicas territoriais, como o urbanismo e o planejamento urbano e regional, as discuss?es geralmente restringem-se ao campo do direito administrativo, de car?ter predominantemente instrumental, cujos efeitos invariavelmente limitam-se ?s a??es pontuais, t?picas e desprovidas da virtude de atingir as causas origin?rias da quest?o urbana.

Thesis (M.Sc. (Geography)) --University of Limpopo, 2018 / Soil erosion, which is a critical component of land degradation, is one of the serious global environmental problems often threatening food security, water resources, and biodiversity. A comprehensive assessment and analysis of remote sensing applications in the spatial soil erosion mapping and monitoring over time and space is therefore, important for providing effective management and rehabilitation approaches at local, national and regional scales. The overall aim of the study was to assess the use of multispectral remote sensing sensors in mapping and monitoring the spatio-temporal variations in levels of soil erosion in the former homelands of Sekhukhune district, South Africa. Firstly, the effectiveness of the new and freely available moderate-resolution multispectral remote sensing data (Landsat 8 Operation Land Imager: OLI and Sentinel-2 Multi-Spectral Instrument: MSI) derived spectral bands, vegetation indices, and a combination of spectral bands and vegetation indices in mapping the spatio-temporal variation of soil erosion in the former homelands of Sekhukhune District, South Africa is compared. The study further determines the most optimal individual sensor variables that can accurately map soil erosion. The results showed that the integration of spectral bands and spectral vegetation indices yielded high soil erosion overall classification accuracies for both sensors. Sentinel-2 data produced an OA of 83, 81% whereas Landsat 8 has an OA of 82.86%. The study further established that Sentinel-2 MSI bands located in the NIR (0.785-0.900 μm), red edge (0.698-0.785μm) and SWIR (1.565-2.280 μm) regions were the most optimal for discriminating degraded soils from other land cover types. For Landsat 8 OLI, only the SWIR (1.560-2.300 μm), NIR (0.845-0.885 μm) region were selected as the best regions. Of the eighteen spectral vegetation indices computed, Normalized Difference Vegetation Index (NDVI) and Soil Adjusted Vegetation Index (SAVI) and Global Environmental Monitoring Index (GEMI) were selected as the most suitable for detecting and mapping soil erosion. Secondly, the study assessed soil erosion in the former homelands of Sekhukhune, South Africa by applying a time-series analysis (2002 and 2017), to track changes of areas affected by varying degrees of erosion. Specifically, the study assessed and mapped changes of eroded areas (wet and dry season), using multi-date Landsat products 8 OLI and 7 Enhanced Thematic Mapper (ETM+)). Additionally, the study used extracted eroded areas and overlay analysis was performed together with geology, slope and the Topographic Wetness Index (TWI) of the area under study to assess whether and to what extent the observed erosional trends can be explained. ii Time series analysis indicated that the dry season of 2002, experienced 16.61 % (224733 ha) of erosion whereas in 2017 19.71% was observed. A similar trend was also observed in the wet season. This work also indicates that the dominant geology type Lebowa granite: and Rustenburg layered its lithology strata experienced more erosional disturbances than other geological types. Slopes between 2-5% (Nearly level) experienced more erosion and vice-versa. On the hand, the relationship between TWI and eroded areas showed that much erosion occurred between 3 and 6 TWI values in all the seasons for the two different years, however, the dry season of 2002 had a slightly higher relationship and vice-versa. We, therefore, recommend use and integration of freely and readily available new and free generation broadband sensors, such as Landsat data and environmental variables if soil erosion has to be well documented for purposes of effective soil rehabilitation and conservation.

This thesis contends that; in mainstream rural residential development around the Australian Capital Territory, use of community title guidelines for sub-division should consider social processes and environmental considerations along-side economic imperatives and interactions. Community title is a form of land tenure that allows for private freehold ownership of land as well as community owned land within the one sub-division. In New South Wales, community title was introduced in 1990 under the Community Land Development Act 1989 (NSW) and the Community Land Management Act 1989 (NSW). Since the introduction of community title, upwards of one hundred and fifty developments, ranging from just a few blocks to the size of small suburbs, have been approved throughout the state. The original aim of community title was to provide a legal framework that underpinned theme-based broad-acre development. Themebased development could include a Permaculture© village, a rural retreat for likeminded equine enthusiasts, or even a medieval village. Community title is also seen as an expedient form of land tenure for both developers and shire councils. Under community title, a developer only has to submit a single development application for a multi-stage development. This can significantly reduce a developer's exposure to risk. From a shire council's perspective, common land and resources within a development, which would otherwise revert to council responsibility for management, becomes the collective responsibility of all the land owners within the development, effectively obviating council from any responsibility for management of that land. Community title is also being touted in planning and policy as a way of achieving 'sustainable' environmental management in new subdivisions. The apparent expediency of community title has meant that development under these guidelines has very quickly moved beyond theme-based development into mainstream rural residential development. Community title effectively provides a framework for participatory governance of these developments. The rules governing a community title development are set out in the management statement, which is submitted to the local council and the state government with the development application. A community association, which includes all lot owners, manages the development. Unless written into the original development application, the council has no role in the management of the common land and resources. This thesis looks at the peri-urban zone around one of Australia's fastest growing cities - Canberra, whose population growth and relative affluence is impacting on rural residential activity in the shires surrounding the Australian Capital Territory. Yarrowlumla Shire, immediately adjacent to the ACT, has experienced a 362 percent increase in population since 1971. Much of this growth has been in the form of rural residential or hobby farm development. Since 1990, about fifteen percent of the development in Yarrowlumla Shire has been community title. The Yass Shire, to the north of the ACT, has shown a forty five percent population increase since 1971. Community title in that shire has accounted for over fifty percent of development since 1990. The thesis case study is set in Yass Shire. The major research question addressed in the thesis is; does community title, within the context of rural residential development around the Australian Capital Territory, facilitate community-based environmental management and education? Subsidiary questions are; what are the issues in and around rural residential developments within the context of the study, who are the stakeholders and what role do they play and; what skills and support are required to facilitate community-based environmental management and education within the context of the study area? To answer the research questions I undertook an interpretive case study, using ethnographic methods, of rural residential development near the village of Murrumbateman in the Yass Shire, thirty kilometres north of Canberra. At the time of the study, which was undertaken in 1996, the developments involved had been established for about four years. The case study revealed that, as a result of stakeholders and residents not being prepared for the management implications of community title, un-necessary conflict was created between residents and between residents and stakeholders. Community-based environmental management issues were not considered until these issues of conflict were addressed and residents had spent enough time in the estates to familiarise themselves with their environment and with each other. Once residents realised that decisions made by the community association could affect them, there developed a desire to participate in the process of management. Eventually, earlier obstacles were overcome and a sense of community began to develop through involvement in the community association. As residents became more involved, the benefits of having ownership of the community association began to emerge. However, this research found that management of a broad acre rural residential development under community title was far more complicated than any of the stakeholders, or any but the most legally minded residents, were prepared for.
