Describing the nature and extent of land resources and changes over time has become increasingly important, especially in developing countries. In this study, two Landsat satellite image scenes were examined to identify land use and land cover changes in Binh Thuan province (Vietnam) between 1990 and 2002. Classification accuracies were based upon ground truth data obtained by global positioning system and field collection. A post-classification comparison analysis was used to identify areas that have experienced conversions in land use and land cover. Comparisons of the land cover maps reveal that a steady growth in population has caused extensive changes of land cover throughout the area. The maps also indicate that the loss of woody land (forest) and the extension of wetlands (irrigate area), combined with built-up encroachment, remains one of the most serious environmental problems facing the Binh Thuan Province today. The post-classification change detection analysis showed that critical habitats accounted for nearly 38.5% of the total intensive study area between 1990 and 2002 while 61.5% remained stable. Results also showed over the 12-year span, approximately 1151.2 km² (115.120 ha) forest were converted respectively to brush, irrigated area (wetlands), cropland and built-up. This is an overall average decrease of approximately 9594 hectares of forested area per year. Throughout the study area, districts most affected by forest conversion to another land cover are: Bac Bihn (2798 ha/year), Than Linh (2717 ha/year), Ham Thuan Nam (1601 ha/year) and Ham Thuan Bac (1524 ha/year). Based on the identified causes of these changes, we made policy recommendations for better management of land use and land cover. [less ▲]

Iron (Fe) is an essential micronutrient. Its low abundance limits primary productivity in more than 30% of the oceans, including the Southern Ocean, and has a crucial impact on the biogeochemical cycles of carbon and other elements with ultimate influence on the Earth climate system. Other trace metals, like Mn, Zn, Co and Cu are also required for microorganisms cell metabolism and may be (co-) limiting. Previous data on dissolved and particulate Fe concentration data showed that Fe is 10-100 times more concentrated in the sea ice than in underlying seawater and that sea ice melt can deliver up to 70% of the daily Fe supply to the surface waters. According to budget estimates in East Antarctica and in the Weddell Sea, accumulated Fe would largely derive from the underlying seawater rather than from atmospheric inputs. Most of the available data of trace metals in the sea ice concern pack ice and Fe. Only very scarce data exist on land-fast ice and on other trace metal concentrations. In this presentation, the general objective is to assess the role of land-fast ice as a source of Fe and other bio-essential trace metals (e.g. Mn, Zn, Cu, Mo, Cd), its impact on primary productivity and on the biological pump. Samples of sea ice, brines and seawater as well as dusts samples have been collected during the land-based sampling program YROSIAE at Cape Evans (Scott Base, McMurdo Sound, Ross Sea, Antarctica) from Nov 2011 to Dec 2011 and from Aug 2012 to Dec 2012. Dissolved and particulate trace metals concentrations have been measured by a recently developed method, which combines multiple element isotope dilution with preconcentration using the Nobias Chelate PA1 resin and ICP-MS analysis. Concentrations of trace metals in snow collected during the present study are one to up to five orders of magnitude higher than the concentrations previously observed in snow from East Antarctica, showing a much stronger dust input of these metals in McMurdo Sound. When comparing the concentrations obtained in the under-ice seawater with those obtained in the snow at McMurdo Sound, concentrations of Fe, Al, Mn, Co are much lower, whereas concentrations of Cu, Zn and Pb are similar and the concentrations of Ni, Mo and Cd are higher. Inventories of these trace metals in the land-fast sea ice give insights on its role as a source of bio-essential trace metal for the fuelling of the seasonal Ross Sea bloom. Other sources of these trace metals will be addressed and compared. [less ▲]

Land´e g-factors are calculated, in intermediate coupling, for 2084 levels belonging to atoms or ions of the sixth row of the periodic table. Extensive configuration interaction and relativistic effects are included in the framework of the relativistic Hartree–Fock approximation including core-polarization effects. The results have been refined using least-squares fittings of the Hamiltonian eigenvalues to the observed energy levels (when available). The new results fill in some gaps in the existing data for a large number of levels belonging to ions of astrophysical interest and are expected to be useful for investigating magnetic fields in CP stars.

Landfill management is an important matter to study in order to set up techniques respectful of the environment. Before any suggestions of management solutions, behaviour of landfills has to be characterised. This is necessary to predict future interactions between a landfill and the neighbourhood, and to estimate the landfill lifetime. Water is one of the most important parameter implied in the biological degradation of refuse, which is a substantial source of pollution. Therefore, this parameter is characterised in terms of quantitative and qualitative data. A relationship between climatic conditions, one of the main source of water, and possible evolution of landfills is propounded. [less ▲]

The European Space Agency (ESA) is planning a Lunar Lander mission in the 2018 timeframe that will demonstrate precise soft landing at the polar regions of the Moon. To ensure a safe and successful landing a careful risk analysis has to be carried out. This is comprised of identifying favorable target areas and evaluating the surface conditions in these areas. Features like craters, boulders, steep slopes, rough surfaces and shadow areas have to be identified in order to assess the risk associated to a landing site in terms of a successful touchdown and subsequent surface operation of the lander. In addition, global illumination conditions at the landing site have to be simulated and analyzed. The Landing Site Risk Analysis software framework (LandSAfe) is a system for the analysis, selection and certification of safe landing sites on the lunar surface. LandSAfe generates several data products including high resolution digital terrain models (DTMs), hazard maps, illumination maps, temperature maps and surface reflectance maps which assist the user in evaluating potential landing site candidates. This paper presents the LandSAfe system and describes the methods and products of the different modules. For one candidate landing site on the rim of Shackleton crater at the south pole of the Moon a high resolution DTM is showcased. * Corresponding [less ▲]

Fitting her research approach within the field of the territorial participative research-action, the PhD student assumes that the participation of the territorial actors and the population can “feed” the scientific research as well as territorial action.

In Egypt, high temperatures, humidity and dusty hot winds lead to excessive discomfort for people. Contemporary designers do not integrate landscape architecture as a way to improve the micro climate of the outdoor built environment, in addition to the inappropriate use of energy resources ,while in Egypt’s hot arid climates, it is essential to ameliorate the microclimate in an energy efficient way. Landscape architects must fully understand that Egypt has one of the harshest and most limiting environments on earth. Therefore, the role of landscape architect is essential in creating a more favourable outdoor environment for people with regard to their inner living space: adequate shade, cooler temperatures, light breezes, protection from glare and wind blown sand. The main aim of this thesis was to provide landscape architects with design principals and design guidelines to improve the microclimate and conserve energy in Egypt. The thesis could be described as horizontal overview that describes historical and recent design solutions that tackle with the problem of aridity and resources scarcity. The research was guided by a design problem that was intended to steer the research in order to come out with the knowledge needed in correspondence to the design problem. The location of the case study or design was in Egypt’s eastern desert and the selection was made based in the aridity and harshness of the project location. This study was divided into 6 parts: (1) Research Design, (2) Background, (3) Lessons from historical landscape design examples, (4) Contemporary Landscape design principals and guidelines, (5) Case Study and (6) Conclusion.
