Trajnostni razvoj na kraških območjih bi moral biti prilagojen posebnostim te pokrajine, posebej njeni ranljivosti. Pravilno vrednotenje razvojnega potenciala in upravljanje s kraškimi območji je zelo pomembno za Slovenijo. V tej knjigi so predstavljene analize vpliva pokrajinskih značilnosti na rabo zemljišč in trajnostni razvoj obmejne slovenske kraške pokrajine ‒ Bele krajine. Da bi opozorili na kombinacijo družbenih dejavnikov in naravnih razmer za celostni pogled na kraško pokrajino, smo uporabili tri pristope: 1. oceno obremenjenosti kraške pokrajine zaradi človeka, 2. analizo sprememb rabe zemljišč in 3. kvantitativno in kvalitativno analizo trajnostnega razvoja Bele krajine. Kraški pojavi na trajnostni razvoj lahko vplivajo tako pozitivno kot negativno. Po mnenju lokalnih deležnikov so pozitivni učinki povezani večinoma s turizmom, negativni učinki pa predvsem v omejenem kmetijstvu. Sklenimo z mislijo, da so kraški pokrajinski pojavi lahko več kot le omejevalni dejavniki, saj imajo tudi razvojni potencial.
The globally important nature of wetland ecosystems has led to their increased protection and restoration as well as their use in engineered systems. Underpinning the beneficial functions of wetlands are a unique suite of physical, chemical, and biological processes that regulate elemental cycling in soils and the water column. This book provides an in-depth coverage of these wetland biogeochemical processes related to the cycling of macroelements including carbon, nitrogen, phosphorus, and sulfur, secondary and trace elements, and toxic organic compounds. In this synthesis, the authors combine more than 100 years of experience studying wetlands and biogeochemistry to look inside the black box of elemental transformations in wetland ecosystems. This new edition is updated throughout to include more topics and provide an integrated view of the coupled nature of biogeochemical cycles in wetland systems. The influence of the elemental cycles is discussed at a range of scales in the context of environmental change including climate, sea level rise, and water quality. Frequent examples of key methods and major case studies are also included to help the reader extend the basic theories for application in their own system. Some of the major topics discussed are: Flooded soil and sediment characteristics Aerobic-anaerobic interfaces Redox chemistry in flooded soil and sediment systems Anaerobic microbial metabolism Plant adaptations to reducing conditions Regulators of organic matter decomposition and accretion Major nutrient sources and sinks Greenhouse gas production and emission Elemental flux processes Remediation of contaminated soils and sediments Coupled C-N-P-S processes Consequences of environmental change in wetlands# The book provides the foundation for a basic understanding of key biogeochemical processes and its applications to solve real world problems. It is detailed, but also assists the reader with box inserts, artfully designed diagrams, and summary tables all supported by numerous current references. This book is an excellent resource for senior undergraduates and graduate students studying ecosystem biogeochemistry with a focus in wetlands and aquatic systems.
IUCN's Protected Areas Management Categories, which classify protected areas according to their management objectives, are today accepted as the benchmark for defining, recording, and classifying protected areas. They are recognized by international bodies such as the United Nations as well as many national governments. As a result, they are increasingly being incorporated into government legislation. These guidelines provide as much clarity as possible regarding the meaning and application of the Categories. They describe the definition of the Categories and discuss application in particular biomes and management approaches.
This book is aimed at students of the natural environment, but it will also appeal to those - cavers, environmental managers and field naturalists - who are curious about the underground world and its inhabitants. it is illustrated throughout with photographs, maps and line diagrams, almost all of which are original to the book.
The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.
A collection of articles on the ecology of North American desert springs, by authors from the fields of biology, botany, ichthyology, conservation, geology and law; and covering both the special traits of springs and the ways in which they might be managed in order to survive.
