La valeur économique des paysages des villes périurbanisées

Journal Articles & Books
December, 2007
France
Europe

In this research, we propose a method for describing rural landscapes in peri urban areas and evaluating their impact on house and land prices. This method matches quantitative geography and econometric methods used for hedonic analysis. A geographical model is used for producing variables describing the landscape an observer can look at when located in a specific house or a land parcel. This model takes account of these parts of the landscape that are hidden by houses, buildings, hills, forests,. . .

Comprendre la dynamique régionale des exploitations de polyculture élevage pour accompagner le développement rural dans les Coteaux de Gascogne

Journal Articles & Books

France
Europe

The Coteaux de Gascogne region, an upland area in south-western France, is a site where studies related to the future of landscapes and the sustainability of natural resource management are well documented. The local agricultural system is induced by a “house centred” society with the particularity of passing on the inheritance and farm estate identically from one generation to the next. This system generates a mosaic landscape made up of field crops, grasslands and woodlots.

cumulative impacts of reclamation and dredging on the marine ecology and land-use in the Kingdom of Bahrain

Journal Articles & Books
December, 2012
Bahrain

This article assesses the ecological and economic impacts of land reclamation and dredging through consulting recent environmental impact assessment reports. Geographic features of Bahrain during 1963–2008 are produced using Geographical Information System. Extensive but inexpensive shallow coastal areas and tidal flats have been reclaimed particularly from 1997 to 2007 at a high rate of 21km²/year. Formal records show the increase in the original land mass by the year 2008 to be 91km².

Turkey

The relief of an area has significant ecological impacts on the climate, vegetation and soil properties of the same area. Relief can show variances depending on steepness, altitudes or roughness of the land surfaces in a landscape are sloppy, low or high; or; rough or smooth. In the scope of this approach, elevation, slope gradients and aspects as landscape relief characteristics in the borders of Ardahan city were evaluated for tourism and recreation use. In order o determine the relief characteristics of the landscape, Geographical Information Systems (GIS) were utilized.

Development of soil information system for the Turkish Republic of Northern Cyprus

Policy Papers & Briefs
December, 2008
Cyprus

In this study, detailed soil information based on Soil Mapping Units (SMU) that were identified during the soil survey were digitized using ArcGIS and Arc-View GIS software in order to create the Soil Information System (SIS) for the Turkish Republic of Northern Cyprus. A total of 7881 mapping units belonging to 109 soil series were compiled into the database. For each SMU geo-referenced physical, chemical and biological attributes in total 20 characteristics were entered. The selection of the criteria is based on the Soil Geographical Database for Eurasia and The Mediterranean.

Changes in the fragmentation and ecological stability of the Morava River floodplain forest in the course of the 20th century

Policy Papers & Briefs
March, 2009
Czech Republic

This paper presents the results of an analysis of the changes in the fragmentation and ecological stability of the floodplain forest geobiocoenoses in the Protected Landscape Area Litovelske Pomoravi, Czech Republic. Using GIS methods, it was determined that the fragmentation within the study area had increased slightly and the ecological stability of the landscape had decreased slightly between the years 1938 and 2006, although the latter remained on a fairly high level.

Eliciting farming decisions of smallholders in response to water availability conditions in Chingale, southern Malawi

Conference Papers & Reports
December, 2012
Malawi
Southern Africa

The objective of this project is to examine adaptation strategies of smallholders in the Chingale district of Malawi to climate change impact, as well as to the implications of introducing the Integration of Aquaculture into Diversified Food production Systems (IADFS). The central approach of this research is combining an agent-based model (ABM) representing farmers with various types of production systems with a water resources model (WRM).
