: This comparative study aims to test the hypothesis according to which environmental awareness of planners is crucial to sustainable cities with a healthy and well connected green infrastructure able to provide ecosystem services. To test the hypothesis, we compared two cities, Bucharest (Romania) and Chisinau (Moldova), based on quantitative analyses using CORINE land cover and use data to analyze the land structure and its dynamic, and qualitative analyses focused on the planning process. Our findings suggest that both cities share a decreasing interest for planning for their green infrastructure, which was lost and fragmented. The process was aggravated in Bucharest by post-communist property restitution. Based on the results, we recommend planners in post-communist countries to give more attention to the green infrastructure, in order to produce plans fitted to the welfare and sustainability needs of people.

: Degree-days (DDs), generically representing the sum of temperature differences between the ambient or outdoor air-temperature and a reference (base) temperature (Tb), may be expressive and useful quantitative tools in assessing the impact of climatic factors on various domains of activity, especially in the context of ongoing climate change processes. Depending on the domain they are applied to, there are four basic types of DDs, out of which the heating (HDDs) and cooling (CDDs) degree-days are used on a large scale as they best reflect the energy needs either for heating or for air-cooling processes in any area. Their practical use mainly derives from how they are calculated; the wide differences between the current calculation techniques showing that hourly (outdoor) air-temperatures produce better estimates, especially if applied for distinct heating or cooling seasons, depending on the thermal response of buildings, but these values are often unavailable. Based on an essentialized review of the existing literature and practice regarding both the calculation methods of HDD and/or CDD values and the types of base temperatures being taken into consideration, this paper presents an experimental case-study carried out for Bucharest town area. It is based on hourly air-temperature values, which were recorded at the four daily measurements hours (01.00, 07.00, 13.00 and 19.00 EET), at the two weather stations located in Bucharest’s town area , namely at Bucharest-Filaret (BF – urban), and Bucharest-Baneasa (BB – extra-urban), during the 1981-2010 period. The resulting annual and monthly degree-days (DDs) below or above several specified base temperatures (0ºC, +10ºC, +17ºC, +19ºC, +21ºC and +23ºC) and the corresponding number of days with daily mean air-temperatures lower or higher than the previously-mentioned base temperatures show that energy demands are greater for indoor cooling in summer than for heating-up in winter, meaning that local authorities and main energy suppliers may thus better plan the seasonal needs for domestic use.

: The purpose of this article is to analyze the multiple forms of the aestheticization of the historic urban landscape, as well as the impact of these practices on the quality, image and identity of heritage spaces, and their appropriation by users and residents. The safeguarded sector of the city of Constantine has undergone a profound aestheticization operation of its built heritage and public space. However, some operations were deficient and they have damaged the historic urban landscape. This raises questions about the reason of this situation, especially, the threat to the image and the identity of the heritage areas. Several hypotheses can be envisaged, including the lack of heritage culture among public stakeholders, ignorance of the status of the safeguarded sector and some management aspects. To confirm this, we adopt a qualitative approach based on the use of several data collection instruments concerning several intervention operations undertaken during the last decade. This research shows that the process of the aestheticization has had several qualities and shortcomings in terms of the requirements of respecting the historical character, the quality of public spaces, and the response to the expectations of users. Understanding the gap could lead to a renewal of the interventions’ modalities in order to preserve and modernize correctly the heritage areas.

Energy and humanity are superimposed. Its importance to mankind and indispensable nature to the world cannot be overemphasized. Public institutions need energy to carry-out their daily activities. The increase in the demand for energy in public institutions can be traced to advancement in technology. Thus, resulted to a sharp increase in the energy consumption, thereby increasing the energy monthly utility bill astronomically. This has put pressure on public institutions in Nigeria, as most of them are heavily indebted to energy companies. Due to constant electric power failure in Nigeria, public institutions rely heavily on diesel generators to argument their daily energy need. Cost minimization and a sustainable clean energy has become a priority for the managers of our public institutions. This study was carried out to establish the exact amount of energy consumption at the Federal Polytechnic Bida, Nigeria, and fashion outways of reducing the cost burden for the institution. The study was achieved through the installation of “Efergy meter” to understudy the energy audit of the institution. Base on the result obtained, the exact amount of energy consumption were established. Solar photovoltaic (PV) system was considered clean and cost-effective options for our public institutions on the long term.

: The systematic information based on concepts, interpretations, ideas, observations, and judgments is known as knowledge. The present study portrayed that the focus of scientific investigations is growing towards assessments based upon environmental knowledge system. The study aimed to understand the interactions between local knowledge systems and decision on land use allocation among rural households in South Africa. Decisions about land-use, resource access, determinants of land-use allocation and environmental knowledge were analysed using descriptive statistics. SPSS was employed to calculate a two-tailed Pearson correlation, multiple regression and ANOVA two-way of variance. Landform condition has a strong impact on the distribution of ecosystems through variation of the climate and controlled land-use. The allocations of land-use as related to landforms reveal both effortless and multifaceted results. A more multifaceted model of land-use allocation occurs on stripping slopes, hills, and foot slopes, which are difficult to access and are covered by forests and scrubland. The study detected a strong linkage between land-use patterns and environmental knowledge. The environmental knowledge acquired either from a formal or an informal resource has significant bearings on land-use patterns, thus being useful for sustainable land-use planning and management. Besides that, how the community allocates land for different purposes is dependent on a multitude of socio-economic factors like land ownership (public or private), economic gains, education, access to credits and other resources.

: This study is a complex analysis of the processes of land degradation by erosion, gullying and landslides, which are a real problem that the territory of the Republic of Moldova faces. The scientific findings from research in the Tigheci Catchment (located northwest of the Tigheci Hills) argue for the region’s huge agricultural potential, but the land degradation processes lead to a reduction in the amount of humus and nutrients in the soil, thus limiting the productivity capacity. The erosion in the soil surface, the most widespread geomorphological process in a basin, has an appreciable intensity especially on the cuesta foreheads and the average rate of soil losses estimated, according to the Mo ț oc method, is 6.3 t/ha/year. Also, characteristic is the process of deep erosion, which is justified by the inventory of a number of 272 gullies, with a predominance of slope gullies that hold over 60% of the ravaged area. The landslides are the third category of geomorphological processes that contribute to land degradation. They cover an area of 4,365.26 ha and are in most cases stabilized. Often, the landslides are caused by the evolution of torrential organisms, which lead to the initiation and development of hollows. Therefore, the degraded land is a rather serious problem that requires practical implementations with real effects in the agricultural system.

: The management of the aggregation-structuring processes implies the intensification of the soil pedoplasm modeling processes under the direct and indirect action of the its biota. In the present research we started from the consideration of algal microflora as the nucleus of bacterial-algal cenosis responsible for the decomposition of various groups of organic substances (geno-metabolic networks). They decompose organic waste in consecutive series ensuring a closed circuit of substances and energy with development of the aggregate level of structural-functional organization of the soil organo-mineral biopedoplasm. It has been established that algalization of the typical moderately humiferous strongly overplowed chernozem through administration of algal biopreparations leads to the regeneration of the humification process and the improvement of the structural-aggregate condition of the soil. The mechanisms of this process are determined by the participation of algal biomass as a source of biological nitrogen for the humification process. Under algalization conditions, the aggregation processes proceed with the formation, mainly, of 5-1 and 3-0.5 mm aggregates and are determined by the agglutination processes with the participation of newly formed humic substances. The intensity of the aggregation-structuring processes differs depending on the species of administered cyanophyte algae and can be described with the following sequence in the sense of decreasing it: Nostoc gelatinosum > Combined lot > Cilindrospermum licheniforme > Calothrix gracilis > Nostoc linckia . The cyanophyte algae participate less in the direct aggregation processes of soil biopedoplasm. At the same time, the practiced technologies require crop rotations capable of contributing to increasing the degree of aggregate stability. In the pedofunctional aspect, the process of algalization of chernozems presupposes perspectives for sustaining the composition and diversity of the soil microbiome.
