  • Perspectives of Land Evaluation of Floodplains Under Conditions of Aridification Based on the Assessment of Ecosystem Services
    DOI: 10.15201/hungeobull.69.3.1Lóczy, D. et al. HungarianHungarian Geographical Geographical Bulletin Bulletin 69 (2020) 69 2020 (3) 227–243. (3) 227–243.227 Perspectives of land evaluation of floodplains under conditions of aridification based on the assessment of ecosystem services Dénes LÓCZY1, Gergely TÓTH2, Tamás HERMANN2, Marietta REZSEK3, Gábor NAGY1, József DEZSŐ1, Ali SALEM3,4, Péter GYENIZSE1, Anne GOBIN5 and Andrea VACCA6 Abstract Global climate change has discernible impacts on the quality of the landscapes of Hungary. Only a dynamic and spatially differentiated land evaluation methodology can properly reflect these changes. The provision level, rate of transformation and spatial distribution of ecosystem services (ESs) are fundamental properties of landscapes and have to be integral parts of an up-to-date land evaluation. For agricultural land capability assessment soil fertility is a major supporting ES, directly associated with climate change through greenhouse gas emissions and carbon sequestration as regulationg services. Since for Hungary aridification is the most severe consequence of climate change, water-related ESs, such as water retention and storage on and below the surface as well as control of floods, water pollution and soil erosion, are of increasing importance. The productivity of agricultural crops is enhanced by more atmospheric CO2 but restricted by higher drought susceptibility. The value of floodplain landscapes, i.e. their agroecological, nature conservation, tourism (aesthetic) and other potentials, however, will be increasingly controlled by their water supply, which is characterized by hydrometeorological parameters. Case studies are presented for the estimation of the value of two water-related regulating ESs (water retention and groundwater recharge capacities) in the floodplains of the Kapos and Drava rivers, Southwest Hungary.

  • Drought and Desertification in Iran
    hydrology Article Drought and Desertification in Iran Iraj Emadodin *, Thorsten Reinsch and Friedhelm Taube Institute for Crop Science and Plant Breeding, Group of Grass and Forage Science/Organic Agriculture, Hermann-Rodewald-Straße 9, 24118 Kiel, Germany * Correspondence: [email protected]; Tel.: +49-431-880-1516 Received: 1 April 2019; Accepted: 5 August 2019; Published: 7 August 2019 Abstract: Iran has different climatic and geographical zones (mountainous and desert areas), mostly arid and semi-arid, which are suffering from land degradation. Desertification as a land degradation process in Iran is created by natural and anthropogenic driving forces. Meteorological drought is a major natural driving force of desertification and occurs due to the extended periods of low precipitation. Scarcity of water, as well as the excessive use of water resources, mainly for agriculture, creates negative water balances and changes in plant cover, and accelerates desertification. Despite various political measures having been taken in the past, desertification is still a serious environmental problem in many regions in Iran. In this study, drought and aridity indices derived from long-term temperature and precipitation data were used in order to show long-term drought occurrence in different climatic zones in Iran. The results indicated the occurrence of severe and extremely severe meteorological droughts in recent decades in the areas studied. Moreover, the De Martonne Aridity Index (IDM) and precipitation variability index (PVI) showed an ongoing negative trend on the basis of long-term data and the conducted regression analysis. Rapid population growth, soil salinization, and poor water resource management are also considered as the main anthropogenic drivers.

The forest/grassland transition zone is especially vulnerable to projected drastic temperature and precipitation shifts in the future. In spite of regional climate conditions is restricted. Ecologically conscious forest policy and management requires the consideration of local conditions, of projections of future climatic conditions and also of non-forest alternatives of land use. The chapter investigates some of the relevant aspects of the ecological role of forests at the dryland edges on the example of three countries/regions on three continents. 55 Chapter 2 1 INTRODUCTION In the drought-threatened regions of the Eurasian and North American forest steppe1 2 has been long considered as crucial in rehabilitating of degraded, over-exploited climatic conditions. resources are presently debated. Due to the limited understanding of interactions between physical processes and land cover, the dispute is still unresolved (Ellison et al. 2011), although the opinion prevails that in the forest steppe zone, water consumption not achieve the goals of environmental protection (Jackson et al., 2005; Sun et al., 2006; Andréassian, 2004; Brown et al., 2005; Wang, Y. et al., 2008). Projected changes in global climate pose a further challenge on dryland ecosystems, as relatively small changes in the moisture balance may lead to considerable ecological shifts.

Blasi 179 PLANT BIODIVERSITY 180 IMPACTS OF CLIMATIC CHANGE IN SPAIN ABSTRACT The direct impacts of climate change on plant biodiversity will occur through two antagonistic effects: warming, which lengthens the period of activity and increases plant productivity, and the reduction in water availability. The projections of the model Promes indicate the first will prevail in the north of the Iberian Peninsula and in the mountains, while the second will affect mainly to the southern half of Spain. Hence, the “mediterraneisation” of the North of the Peninsula and the “aridification” in the South are the most significant tendencies for the next century. The more severe scenario involves a climatic displacement of almost a whole bioclimatic belt, particularly in the South, whereas in the more moderate scenario the change is equivalent to half of the altitudinal interval of a belt. Such displacements exceed the migration thresholds of most species. The biggest indirect impacts are those deriving from edaphic changes, changes in the fire regime and the rise in sea level. Interactions with other components of global change (land use changes, modification in atmospheric composition) constitute another important potential source of impacts for which evidence is now beginning to accumulate.

  • TERC Submission Environmental Protection Services NT
    EXECUTIVE SUMMARY The contents of this submission seek to define the potential of accounting for and investing in natural capital to produce income, improve environmental outcomes and improve landscape resilience. We address this with reference to natural capital, carbon and water and broadly address the methodologies to repair landscapes, thereby facilitating the potential to receive income from the carbon and natural capital markets. We note general landscape degradation over widespread areas of the NT. Mechanisms causing the degradation vary however eroded, dehydrated, less diverse and less productive landscapes are the all too common result. Nature based solutions are a logical investment. They are typically cost effective and offer benefits potentially worth billions of dollars a year to the NT through increased income, environmental resilience and human health outcomes. We use examples that have synergies with various other submissions and plans but emphasize a thought and decision making process with solutions focused on assessing and using multiple potentials in any given situation rather than advocating a specific plan. Investment can be considerable and some returns slow to be realised, but they then tend to grow exponentially to capacity. What gets financed gets done. We suggest any stimulus funding should be connected to long term environmental outcomes as there is an imperative to make decisions and investments that help shift us to a resilient sustainable approach to future economic growth and development. Defining or agreeing methodologies to account for impact of actions taken and finance mechanisms are the primary blocks to the market. These issues can be overcome, indeed much has already been done and this space dynamic.

  • Assessing the Record and Causes of Late Triassic Extinctions
    Earth-Science Reviews 65 (2004) 103–139 www.elsevier.com/locate/earscirev Assessing the record and causes of Late Triassic extinctions L.H. Tannera,*, S.G. Lucasb, M.G. Chapmanc a Departments of Geography and Geoscience, Bloomsburg University, Bloomsburg, PA 17815, USA b New Mexico Museum of Natural History, 1801 Mountain Rd. N.W., Albuquerque, NM 87104, USA c Astrogeology Team, U.S. Geological Survey, 2255 N. Gemini Rd., Flagstaff, AZ 86001, USA Abstract Accelerated biotic turnover during the Late Triassic has led to the perception of an end-Triassic mass extinction event, now regarded as one of the ‘‘big five’’ extinctions. Close examination of the fossil record reveals that many groups thought to be affected severely by this event, such as ammonoids, bivalves and conodonts, instead were in decline throughout the Late Triassic, and that other groups were relatively unaffected or subject to only regional effects. Explanations for the biotic turnover have included both gradualistic and catastrophic mechanisms. Regression during the Rhaetian, with consequent habitat loss, is compatible with the disappearance of some marine faunal groups, but may be regional, not global in scale, and cannot explain apparent synchronous decline in the terrestrial realm. Gradual, widespread aridification of the Pangaean supercontinent could explain a decline in terrestrial diversity during the Late Triassic. Although evidence for an impact precisely at the boundary is lacking, the presence of impact structures with Late Triassic ages suggests the possibility of bolide impact-induced environmental degradation prior to the end-Triassic. Widespread eruptions of flood basalts of the Central Atlantic Magmatic Province (CAMP) were synchronous with or slightly postdate the system boundary; emissions of CO2 and SO2 during these eruptions were substantial, but the contradictory evidence for the environmental effects of outgassing of these lavas remains to be resolved.
