Land Evaluation

Az 1990-es években újraindult, több egyetem és kutatóintézet részvételével folyó hazai földminősítési kutatások két évtizeden átívelő munkálatai révén kidolgozásra került az ún. D- e -Meter földminősítési rendszer. A földminőségre ható talajtani és klimatikus tényezők parametrizálását nagy mintaszámú, idősoros növénytermesztési és talajvizsgálati adatok alapján, valamint a klimatikus agrárpotenciált tükröző nagytájak és Magyarország agroökológiai fajspecifikus paramétereire (Szász , 1999, 2002) támaszkodva végeztük. A vizsgálati adatbázist az 1980-as években az Agrokémiai Információs és Irányítási Rendszer keretei között begyűjtött adatok (mintegy 80.000 parcella öt évre szóló adatai), valamint részletes talajtérképeket is tartalmazó mintaterületi adatbázisok jelentették. A D- e -Meter projekt földminősítési kutatási eredményeit összegezve elmondható, hogy kialakításra került egy új, környezeti elemeket alapul vevő földminősítési rendszer, ami: – statisztikai vizsgálatokon nyugszik és kvantitatív módon határozza meg a termőhelyek produkciós potenciálját; – a művelésben álló, vagy művelésbe vonható hazai talajféleségekre, ill. valamennyi szántó termőhelyre érvényes; – a főbb gazdasági növények, illetve növénycsoportok szerinti értékelést is ad; – tartalmazza a klimatikus hatásokból eredő, talajtani és földtani tényezőkön keresztül érvényesülő termékenységcsökkenés és termelési kockázat (aszály, belvíz) kifejezésének lehetőségét; – a produkciós viszonyokat különböző művelési intenzitási szinteken is jellemzi; – a földminőségről mezőgazdasági parcella szinten is megbízható információt nyújt. A D- e -Meter földminősítési módszer kidolgozásával és annak informatikai rendszerbe integrálásával megteremtődtek az alapok a sokat bírált aranykoronás földértékelési rendszer kiváltásának, valamint a környezetgazdálkodás magasabb szintű tervezésének is.

Over the next fifty years, most new wealth will be accumulated in cities; this includes physical infrastructure (road, rail, electricity, telecommunications and sanitation), productive capital (houses, offices and factories) and knowledge capital (skills, knowhow and ideas). The development of cities will also determine humanity’s ability to preserve natural capital. Consequently, urbanization deserves urgent attention from policymakers, academics and businesses worldwide. The current global urbanization project is peaking and within a century it will be all but over. The richest and fastest growing cities are those which increasingly specialize in knowledge-based sectors, facilitating the flow of knowledge across people, institutions and enterprises. Well-governed, connected, clean and uncongested cities are likely to attract productive capital, talent and creativity. But the consequences of bad governance and inaction over planning can stymie performance and erode human welfare for decades or centuries.

Karst features such as polje are highly vulnerable to natural and anthropogenic pollution. The main objectives of this study were to investigate the soil quality in the Ioannina polje (north-west Greece) concerning arsenic (As) and zinc (Zn), and delineate their origin as well as compare the As and Zn content in soil with criteria recorded in the literature. For this purpose, the geomorphological settings, the land use, and the soil physicochemical properties were mapped and evaluated, including soil texture and concentrations of aqua-regia extractable As and Zn. The concentration of elements was spatially correlated with the land use and the geology of the study area, while screening values were applied to assess land suitability. The results reveal that 72% of the total study area has a very gentle slope. This relief favors urban and agricultural activity. Thus, the urban and agricultural land used cover 92% of the total area. The spatial distribution for As and Zn in the soil of the study area is located on very gentle slopes and is strongly correlated with the geological parent materials and human-induced contamination sources. Arsenic and Zn can be considered enriched in the soil of the area studied. The median topsoil contents (in mg kg−1) for As (agricultural soil 16.0; urban soil 17.8) and Zn (agricultural soil 92.0; urban soil 95.0) are higher compared to the corresponding median values of European topsoils. Land evaluation suitability concerning criteria given from the literature is discussed. The proposed work may be helpful in the project of land use planning and the protection of the natural environment.

Marine Ecosystem Services

The biotic and abiotic assets of the marine environment form the “marine natural capital” embedded in the global ocean. Marine natural capital provides the flow of “marine ecosystem services” that are directly used or enjoyed by people providing benefits to human well-being. They include provisioning services (e.g., food), regulation and maintenance services (e.g., carbon sequestration and storage, and coastal protection), and cultural services (e.g., tourism and recreational benefits). In recent decades, human activities have increased the pressures on marine ecosystems, often leading to ecosystem degradation and biodiversity loss and, in turn, affecting their ability to provide benefits to humans. Therefore, effective management strategies are crucial to the conservation of healthy and diverse marine ecosystems and to ensuring their long-term generation of goods and services. Biophysical, economic, and sociocultural assessments of marine ecosystem services are much needed to convey the importance of natural resources to managers and policy makers supporting the development and implementation of policies oriented for the sustainable management of marine resources. In addition, the accounting of marine ecosystem service values can be usefully complemented by their mapping to enable the identification of priority areas and management strategies and to facilitate science–policy dialogue. Given this premise, this study aims to review trends and evolution in the concept of marine ecosystem services. In particular, the global scientific literature on marine ecosystem services is explored by focusing on the following main aspects: the definition and classification of marine ecosystem services; their loss due to anthropogenic pressures, alternative assessment, and mapping approaches; and the inclusion of marine ecosystem services into policy and decision-making processes.
