APPLICATION ON GIS FOR LAND USE PLANNING IN CENTRAL PART OF ALBANIA, MAMINAS COMMUNE

Journal Articles & Books
Mars, 2011

New developments in geographic information science and technology are changing the way we apply GIS to developing-world agriculture, creating new opportunities to utilize the technology to address problems of disaster management, climate change, land use change, land degradation, crop analysis and impact assessment.GIS allows data and demographic information to be presented graphically, primarily in maps, but also in business tools such as charts, graphs and other reports.

GIS-based land suitability analysis integrating multi-criteria evaluation for the allocation of potential pollution sources

Journal Articles & Books
Décembre, 2013
Lituanie

The geological environment has been heavily polluted by chemical substances over the past few decades. Pollution sources located on the earth’s surface or underground have affected the quality of the environment. A significant amount of impact could be reduced if the allocation of potential pollution sources was based on an evaluation of environmental conditions. The main objective of this study was to develop a methodology for the allocation of potential pollution sources by employing GIS and multi-criteria evaluation techniques.

This work describes a methodology for Strategic Environmental Assessment of urban areas in Latin America based on the recently approved European Planning Directive, and applies it to the Metropolitan Area of Concepción (Chile). The method is based on the Land Suitability Index (LSI), a cartographic GIS-based index originally developed for the region of Barcelona (Spain) and aimed at determining the suitability of each point in a region for urban development, considering three sub-indexes: (i) Naturalness, (ii) Ecological Connectivity and (iii) Natural Risk.

Classification of hazelnut cultuvation areas for agricultural suitability in the eastern Black sea region, case study; Unye-Tekkiraz district

Turquie

The aim of this research was to determine physical land evaluation of hazelnut areas of Ordu-Unye and its vicinity. The study area, is located between west of Ordu and south of Samsun provinces, at coordinates 4542500-4537500 km N and 342500-347500 km E (UTM), covers approximately 31.5 km2. The study area consists of various topographic features such as, hilly and rolling physiographic units commonly. Elevation varies from 200 m to 600 m above sea level. Average annual precipitation and temperature are 1162.4 mm and 14.2ºC, respectively.

To retire or expand? A fuzzy GIS-based spatial multi-criteria evaluation framework for irrigated agriculture

Journal Articles & Books
Décembre, 2010
Australie

This paper presents a GIS framework for multi-criteria evaluation of land suitability for the expansion or retirement of irrigated cropland at a catchment scale in Australia. This framework is based on the fuzzy linguistic ordered weighted averaging (FLOWA) approach which integrates the analytical hierarchy procedure (AHP) and quantifier-guided OWA operators in an ArcGIS 9.2 environment. The FLOWA module proved to be highly flexible and efficient in generating and visualising a wide range of different multi-criteria decision strategies.

Ecological suitability evaluation for mountainous area development based on conceptual model of landscape structure, function, and dynamics

Journal Articles & Books

Chine

Minimizing the ecological impact of land development is a fundamental principle of sustainable development. Ecological suitability assessment is the key to realizing sustainability and is also significant for optimizing spatial patterns of territorial development. Especially in mountainous areas where the ecosystem is both vulnerable and important, quantitative evaluation of ecological suitability for land development is particularly important and urgent given current development strategy of urban construction in mountainous areas in China.

The security district of Hatay, Kilis, Gaziantep, Sanliurfa, Mardin and Sirnak province located along southern boundary lies between Turkey and Syria that comprised wide areas. It is considered to evaluate of cleaned mined land with a 300-400 m width and 510 m length. It was estimated that these lands were very productive and that can be used for organic or other types of agriculture .If these lands are cleaned and opened to agriculture, that can create jop opportunities to many families in agriculture.

Integration of MultiCriteria Decision Analysis in GIS to develop land suitability for agriculture: Application to durum wheat cultivation in the region of Mleta in Algeria

Journal Articles & Books
Décembre, 2012
Algérie

Due to constant decrease in farmlands, it is important to identify the best lands useful for sustainable agriculture (productive and profitable agriculture that protects the environment and that is socially equitable). This requirement has resulted in the development of land suitability maps for agriculture by combining several factors of various natures and of differing importance.

Digital mapping of a soil drainage index for irrigated enterprise suitability in Tasmania, Australia

Journal Articles & Books
Décembre, 2014
Australie

An operational Digital Soil Assessment was developed to inform land suitability modelling in newly commissioned irrigation schemes in Tasmania, Australia. The Land Suitability model uses various soil parameters, along with other climate and terrain surfaces, to identify suitable areas for various agricultural enterprises for a combined 70000-ha pilot project area in the Meander and Midlands Regions of Tasmania. An integral consideration for irrigable suitability is soil drainage.

Land suitability analysis for Tabriz County, Iran: a multi-criteria evaluation approach using GIS

Décembre, 2013
Iran

In our research we investigated the optimal utilization of land resources for agricultural production in Tabriz County, Iran. A GIS-based Multi Criteria Decision Making land suitability analysis was performed. Hereby, several suitability factors including soils, climatic conditions, and water availability were evaluated, based on expert knowledge from stakeholders at various levels. An Analytical Hierarchical Process was used to rank the various suitability factors and the resulting weights were used to construct the suitability map layers.

Assessment of Land Suitability Potentials for Selecting Winter Wheat Cultivation Areas in Beijing, China, Using RS and GIS

Journal Articles & Books
Décembre, 2011
Chine

It is very important to provide reference basis for winter wheat quality regionalization of cultivation area. The aim of this article was based on factors affecting wheat quality and setting realistic spatial models in each part of the land for assessment of land suitability potentials in Beijing, China. The study employed artificial neural network (ANN) analysis to select factors and evaluate the relative importance of selected environment factors on wheat grain quality.

Nova versão do sistema de avaliação de terras - SIAT

The SIAT is a specialist system for Land Evaluation derived from the MicroLEIS - Land Evaluation Information System developed in Spain. In its first version the 12 variables were adapted and adjusted for tropical conditions as well as the program structure and databank. In that time the field tests showed that the best results were obtained for scales near 1:100.000. In this second version the ranges for each variable were redefine and a communication interface with the GIS IDRISI was introduced, which allowed the exchange of data between the two programs.
