    ASPECTE PRIVIND INFRASTRUCTURA ECOLOGICĂ URBANĂ ȘI FURNIZAREA SERVICIILOR ECOSISTEMICE
    (CEP USM, 2024) Țugulea, Andrian; Mogîldea, Vladimir; Bejan, Iurii
    The present paper presents the results regarding the role of the ecological infrastructure in the Balti urban ecosystem in the provision of ecosystem services. Modern methods of land use analysis were used, followed by the quantifcation of ecosystem services (air purifcation, carbon storage, water retention). It was established that in the municipality of Balti, agricultural land predominates - 51% (4001.44 ha), followed by construction and courtyards - 28% (2138.25 ha), forests -9% (722.75 ha) , lands occupied by water and lands for streets and markets with 4% each, roads - 3%, and other lands including degraded. In the rural area, agricultural land predominates, and in the urban area - buildings and yards. The urban green infrastructure in the Balti urban ecosystem can remove approximately 51.6 t/year of particles from the air, store 116.5 thousand tons of carbon and retain rainwater in case of 10 mm precipitation - 289.8 thousand t/ year.

    ABORDĂRI METODOLOGICE DE CERCETARE A STĂRII ECOLOGICE A ECOSISTEMELOR URBANE
    (CEP USM, 2024) Mogîldea, Vladimir
    Urban ecosystems represent mainly human habitats, but usually include significant are as for wild species that are associated with urban habitats. They are socio-ecological systems composed of ecological infrastructure (green and blue) and built infrastructure (grey one). Envi ronmental Infrastructure (EI) provides a wide range of benefits for the population: it reduces air pollution, water pollution, noise pollution, provides protection against floods, droughts and heat waves and maintains a connection between people and nature. Urban ecosystems are considered to be in “good condition” if living conditions for people and urban biodiversity are good. Ano ther criterion refers to the balance within the ecosystem, between built and green infrastructure. The environment quality assessment in urban ecosystems requires a specific methodological ap proach, adapted to the complexity of this ecosystem type. The methodology includes a framework of indicators for assessing the ecological state of urban ecosystems, mapping them to help design or implement policies on urban green infrastruc ture, its biodiversity as well as to measure progress towards international, national, regional or local goals in terms of stability and sustainability of urban ecosystems.

    ASPECTE ÎN CONSERVAREA BIODIVERSITĂȚII: STUDIU DE CAZ - REGIUNEA DE DEZVOLTARE NORD
    (CEP USM, 2024) Donica, Ala; Mogîldea, Vladimir
    The study proposed the conservation of biodiversity analysis in the Northern Development Region of the Republic of Moldova, through state-protected natural areas and ecological ne tworks, with the identification of the natural heritage elements dependence on environmental factors (abiotic, biotic, anthropogenic). In the region, the geological structure, the outcrops of the Badenian-Sarmatian deposits, the specific relief, the narrow valleys in the form of gorges, in com bination with other environmental components (soil, climate, water) present favorable habitats for the development of various types of ecosystems (petrophyte, forest, grasslands, wetlands, etc.) and rare species. Areas vulnerable to nutrient and nitrate pollution have been identified, where maintenance or improvement of water status is an important factor for protected areas in the Emerald network and wetlands of international importance. Biodiversity conservation actions in the region should respond to several environmental problems, among which: the presence of limited protected natural areas, insufficient to ensure the biodiversity conservation; fragmenta tion of natural ecosystems and habitats; intensification of the environmental changes impact on the system of wetlands and their associated natural ecosystems; the presence of limited urban/ rural green spaces, insufficient to ensure the ecological norms in the field; the negative impact of agricultural activities, especially in ecotone areas, etc.
