Land Use And Human Impact In The Dinaric Karst, Ivan Gams, Matej Gabrovec
International Journal of Speleology
The article presents Dinaric karst, human impacts in the area, and its long history of deforestation, transformation into stony semi-desert, and a century long reforestation, where plans to restore the primary thick soil were just hoping against hope.
Agriculture And Nature Conservation In The Moravian Karst (Czech Republic), Ivan Balák, Jozef Janèo, Leos Stefka, Pavel Bosák
Agriculture And Nature Conservation In The Moravian Karst (Czech Republic), Ivan Balák, Jozef Janèo, Leos Stefka, Pavel Bosák
International Journal of Speleology
Moravian karst is a narrow strip of limestone with long history of settlement, agricultural use and man impact to karst. It is naturally divided into smaller units - karst plateaus - separated by deep valleys (glens). Each plateau has different proportion of land use, i.e. the percentage of agricultural land, forests, etc. The agricultural land constitutes now up to 70% in the north and max. 30% in the centre and south of the total area of plateaus. Intensive agricultural use of the arable land since 60ties of this Century caused great impact to quality of soils and groundwater by overdoses …
Sustainable Development Of Agriculture In Karst Areas, South China, Linhua Song
Sustainable Development Of Agriculture In Karst Areas, South China, Linhua Song
International Journal of Speleology
The exposed carbonate rocks aged from Sinian to Mid-Triassic Periods cover an area of 500,000 km2 in south-west China. In karst areas with spectacular landscapes characterized by magnificent tower karst and conical karst, rare surface drainage systems and prevalent subsurface drainage systems, the environment is ecologically very fragile. The rapid increase of population, over deforested and cultivated lands, worsted the ecological system, causing a higher frequency of draught, flood and various disasters, backward economic development, low living standard of the people. In order to improve the sustainability of the agriculture the experience shows that the following operations should be …
Karst And Agriculture In Australia, David Gillieson, Mia Thurgate
Karst And Agriculture In Australia, David Gillieson, Mia Thurgate
International Journal of Speleology
Much of the development and degradation of karst lands in Australia has occurred in the last two centuries since European settlement. Recent prolonged El Niño events add further climatic uncertainty and place real constraints on sustainable agriculture. The lower southeast of South Australia is perhaps the one area in Australia where karst, and particularly karst hydrology, impinge on the daily lives of the community in that pollution and overexploitation of the aquifer are readily apparent to the local population. Effluent from intensive dairy farms, piggeries and cheese factories enters the karst and has caused concern over pollution of water supplies. …
Agricultural Use And Water Quality At Karstic Cuban Western Plain, Juan Reynerio Fagundo Castillo, Patricia González Hernandez
Agricultural Use And Water Quality At Karstic Cuban Western Plain, Juan Reynerio Fagundo Castillo, Patricia González Hernandez
International Journal of Speleology
In the paper some results of studies on the karstic aquifers of the western plain of Cuba are presented and discussed. The intensive exploitation of these aquifers for agriculture use and drinking water supply induces an increase of marine water intrusion, water salinisation and a progressive increase of chemical corrosion with a greater dissolution of carbonates. During the period of study (1983-1998) a trend in the deterioration of water quality was observed by means of a chronological series of hydrochloride content.
Transit Gis Applications In Fairfax County, Virginia, Wenyu Jia, Brendan Ford
Transit Gis Applications In Fairfax County, Virginia, Wenyu Jia, Brendan Ford
Journal of Public Transportation
The Fairfax County Department of Transportation (DOT) manages a fixed-route bus system (the Fairfax Connector) that encompasses 58 routes. To better support the planning, operation, and marketing of this bus system, the Fairfax County DOT and the Fairfax County Department of Information Technology formed a team to develop a pilot project of Geographic Information Systems (GIS) transit applications. These applications would serve as a demonstration to facilitate automation, analysis, accessing, and plotting of transit data. To be successful, the applications had to be cost effective and match users' technical needs with their abilities. Paramount to the success of this project …
Transit Stations And Commercial Property Values: A Case Study With Policy And Land-Use Implications, Arthur C. Nelson
Transit Stations And Commercial Property Values: A Case Study With Policy And Land-Use Implications, Arthur C. Nelson
Journal of Public Transportation
There is little research about the association between rail transit station proximity and commercial property values. There is even less research on the role of public policy in influencing commercial property markets near transit stations without resorting to supply-side constraints. The research reported in this article helps close these gaps in research. This article develops a theory on commercial property value with respect to both transit station proximity and the role of policies that encourage commercial development around transit stations without discouraging commercial development elsewhere. The theory is applied to the universe of commercial property sales in the area of …
Impacts Of Agricultural Transformation On The Principal Karstic Regions Of France, Jean Nicod, Jean-Noël Salomon
Impacts Of Agricultural Transformation On The Principal Karstic Regions Of France, Jean Nicod, Jean-Noël Salomon
International Journal of Speleology
The recent extension of intensive agriculture on the karst plateaus has caused different types of impact: soil management, generalised and/or localised pollution. Yet paradoxically rural depopulation can also have negative impacts, which largely depend on the characteristics and the hydrological function of the different karst environments. They are often negative, particularly as far as the water quality is concerned, which is why protection measures are undertaken, either in a defined area for a catchment, or in the framework of regional parks. But this is not always the case, so it is appropriate to analyse the problem of karst pollution as …
Interaction Between Karst, Water And Agriculture Over The Climatic Gradient Of Israel, Amos Frumkin
Interaction Between Karst, Water And Agriculture Over The Climatic Gradient Of Israel, Amos Frumkin
International Journal of Speleology
The dry climate of Israel and the karstic nature of its rocks have always imposed human innovation for utilisation of water resources and agriculture. Large perennial karst springs are available only in the lowlands, but sophisticated water supply systems were built both in the lowland and highland regions. Marl layers interbedded within carbonates give rise to local perched springs and allow terrace construction. Deforestation has taken place for some 4000 years, causing intense soil erosion, but terraces have reduced this impact.

The Advanced Technology Bus And The Evolution Of Workplace Expertise, David W. Partain
The Advanced Technology Bus And The Evolution Of Workplace Expertise, David W. Partain
Journal of Public Transportation
The purpose of this paper is to define and explore the immediate and long term effects and the resulting organizational dynamics of advancing technology on maintenance workplace expertise in transportation. In the past ten years the face of maintenance in the transportation workplace has completely changed as computerization has taken over the control of transmissions, engines, and bus/truck environmental systems and transformed them from "closed" stand alone components to an interdependent "open system" in a state of constant communication. The immediate future brings with it the advanced technology of the Intelligent Transportation System with its Geographic Information System, in-vehicle logic …

Agriculture, Landscape And Human Impact In Some Karst Areas Of Italy, Ezio Burri, Benedetta Castiglioni, Ugo Sauro
Agriculture, Landscape And Human Impact In Some Karst Areas Of Italy, Ezio Burri, Benedetta Castiglioni, Ugo Sauro
International Journal of Speleology
Italy is made up for about 1/5 of its surface by soluble rocks, which represent the arena of karst environments. The karst morpho-units, some hundreds, are mainly distributed inside the alpine structure of the Mediterranean mountains. A very large number of rock formations are present, different in facies, lithology, age, etc. Among these, carbonate rocks prevail, followed by gypsum and salt. Most of the carbonate rocks are limestones sedimented in a platform environment and they show a wide range of porosity, frequency of fractures and bedding planes. The climatic processes, the expression of some different sub-types of Mediterranean climate (from …
Information As Verb: Re-Conceptualizing Information For Cognitive And Ecological Models, David G. Casagrande
Information As Verb: Re-Conceptualizing Information For Cognitive And Ecological Models, David G. Casagrande
Journal of Ecological Anthropology
Current notions of information are inadequate for ecological and cognitive models because they: 1) only account for information gain that results from reducing uncertainty; 2) assume binary logic; 3) fail to account for semantics and pragmatics; and 4) can not account for shared and externalized cognition. A different model of information is presented here, which treats information as a process of state change (i.e., the term is used as a verb), rather than as a variable. The potential for information is defined to include not only stimuli, but the context of the informational moment; and is distinguished from realized information, …
Agriculture, Grazing And Land Changes At The Serra De Tramuntana Karstic Mountains, Ángel Ginés
Agriculture, Grazing And Land Changes At The Serra De Tramuntana Karstic Mountains, Ángel Ginés
International Journal of Speleology
Karst landforms are one of the most outstanding characteristics of the Serra de Tramuntana range on the island of Mallorca, especially regarding traditional farming and the landscape wilderness. Good examples of polje-like depressions, dolines, karstic gorges and karrenfields are widely distributed over the mountain range. Owing to karrenfields occupying a large surface area in the Serra to the exclusion of arable land, the traditional activity based on the repetitive burning of the Ampelodesmos mauritanica brushwoods for cattle-raising promotes hastening deforestation and soil removal.

Prospectus For Information Ecology, John R. Stepp
Prospectus For Information Ecology, John R. Stepp
Journal of Ecological Anthropology
Information Ecology (hereafter IE) is a field of inquiry being developed, in part, by members of the Department of Anthropology, University of Georgia (Appendix A). The following prospectus represents a work in progress and is the latest incarnation in a series of revisions since the first IE prospectus was developed in 1990 (Appendix B). The purpose of the prospectus is not to bound what is, admittedly, an eclectic mode of investigation, but rather to outline a field of inquiry that is inherently multidisciplinary and seeks theoretical complementarity both among disparate fields and levels of analysis. The goals are as follows: …
Practical Field Considerations For Time Allocation Study, Eileen Mueller
Practical Field Considerations For Time Allocation Study, Eileen Mueller
Journal of Ecological Anthropology
This paper briefly describes four methods of time allocation study and examines the use of one of them, the "random spot-check," in the field. Time allocation methods provide quantitative data that is particularly useful for environmental or ecological research in anthropology. Practical problems of implementation, however, often override their theoretical usefulness. The "random spot-check" technique can be hindered by unforeseen time constraints and social considerations. The insightful data generated through this field method, however, may make it worthwhile for the researcher to attempt to overcome its practical limitations and include it in his or her research project.

Land Use In The Karstic Lands In The Mediterranean Region, Ibrahim Atalay
Land Use In The Karstic Lands In The Mediterranean Region, Ibrahim Atalay
International Journal of Speleology
Karstic lands have special importance in terms of soil formation and land-use. Soil appears only on the flat and slightly undulating karstic lands, while soils are found along the cracks and bedding surfaces between the layers on the hilly karst areas although these lands are rocky in appearance. Karstic lands in the hilly area are not conducive to cultivation. But rocky areas create a favourable habitat for the growth of forests except in an arid climate. Because the tree roots easily follow and develop along the cracks in the limestone. As a general rule soil erosion does not occur on …
