Europa

Land fragmentation is a problem in Europe, and Estonia is not an exception in this respect. Parcel size is widespread characteristic to describe the level of fragmentation. The aim of the study is to find out if there is difference of fragmentation among different groups of landholdings by size. In order to characterise land fragmentation, were calculated the Januszewski and Schmook indexes, average parcel size and average distance from the gravity centre of each landholding to its parcels. Results showed a high level of fragmentation of Estonian agricultural landholdings.

Topography impact on nutrition content in soil and yield

Policy Papers & Briefs
Junho, 2008

The main aim of this study was to determine the dependence of yield and selected soil properties on topography of the experimental field by using topographical data (elevation, slope and flow accumulation). The topography and yield data were obtained from a yield monitor for combine harvester, soil properties data were taken from sampling points of our experimental field. Initially, the topographical parameters of elevation and slope were estimated and then the Digital Elevation Model (DEM) grid was created.

Assessing the stream water quality dynamics in connection with land use in agricultural catchments of different scales

Policy Papers & Briefs
Julho, 2008
República Checa

We introduce a simple method for estimating the changes of nitrate concentrations in surface waters regarding the land use modification. Stream and drainage water nitrate concentrations in prevailingly agricultural catchments of three different scales located in the Crystalline complex of the Czech massif, Czech Republic, were included in this study. Water quality samples were collected through the years 1992-2006 at monthly and bi-monthly intervals.

Drought analysis of Aksu Irrigation Area in Antalya by Aydeniz Method and geographic information systems

Policy Papers & Briefs
Dezembro, 2014
Turquia

In this study, a drought analysis has been carried out for Aksu-Antalya Irrigation Area by using Aydeniz Method and Geographic Information Systems. Meteorological data of Antalya, Isparta, Korkuteli and Manavgat stations including temperature, precipitation, humidity and sunshine hour were used. Annual drought maps were generated by using ArcGIS 10. According to the results of the study, there were no drought periods from 1985 to 2006.

Integrating geo-information models with participatory approaches : applications in land use analysis

Journal Articles & Books
Dezembro, 2004
Índia

In this thesis we demonstrate some methods to integrate biophysical data with socio-economic variables with applications in agricultural land use analysis. Part of Nizamabad District of Andhra Pradesh State in India is considered for developing and testing the methods developed. First the study area is stratified as a pre-field work exercise for a focused land use analysis.

Determination of potential grapevine (Vitis spp.) cultivation areas of Turkey based on topographic and climatic factors by using Geographic Information Systems (GIS) Techniques

Policy Papers & Briefs
Dezembro, 2015
Turquia

Turkey is homeland of the grapevine (Vitis spp.), one of the most important agricultural products in the World. Our country, having the favorable climatic conditions for viticulture, has an important role among the viticulture farming countries of the World. The objective of this study is to determine potential growing areas of grape in Turkey by using Geographic Information Systems techniques based on topographic and climatic factors. It is important to efficiently use of our limited arable lands from the agricultural point of view.

Evaluating the ecological suitability of the vineyards, by using geographic information systems (GIS)

Journal Articles & Books
Dezembro, 2010
Romênia

In this scientific paper are presented the preliminary results of the research having as goal to establish a methodology for the determination of the oenoclimatic potential and its spatial distribution in the viticultural areas. Data were obtained by means of GIS technology and disclosed a new, original model for analysing the viticultural ecoclimate.

Technology and precision of automatized deciphering of agricultural lands

Policy Papers & Briefs
Dezembro, 2012
Estados Unidos
Bielorrússia

In the conditions of the Republic of Belarus there was presented the technology of automatized deciphering of area objects with the help of programme complex ENVI ((Environment for Visualizing Image), developed by the Research Systems, Inc. (the USA)). There were examined existing methods of deciphering in the programme complex ENVI. The presented order of deciphering could be recommended for production and could be used for the deciphering of linear and single-point objects.

Monitoring and assessing groundwater level by GIS:A case study in the irrigated soils of Bafra Plain in Northern Turkey

Policy Papers & Briefs
Dezembro, 2011

This study aimed to determine monthly and seasonal ground water level variations of agricultural soils of the right-land irrigated area in Bafra Plain using Geographical Information systems (GIS). To achieve this purpose, ground water levels were monitored at 62 different points. The maps of problematic areas for drainage were developed using the highest and lowest ground water levels to determine the problems caused by high ground water level.

General distribution potential agricultural areas of Samsun province and importance of soil survey and mapping

Policy Papers & Briefs
Dezembro, 2011

Recently, studies on land consolidation and valuation in farm lands have became more important due to a new soil conservation law (2005, 5403 numbered) and European Union Integration processes in our country. However, each soil group determined by morphometric system in agricultural lands have its own land use and management practices. Description and determination of soil properties are not sufficiently made by considering old soil classification system. Nowadays, Soil Taxonomy preferred by many countries in the world has been used for soil classification.

Land-use/land-cover dynamics in Chiang Mai: Appraisal from remote sensing, GIS and modelling approaches

Policy Papers & Briefs
Agosto, 2006
Tailândia

Remotely-sensed images and Geographical Information Systems (GIS) data were integrated into the SLEUTH cellular automata (CA) model to analyze land-use/land-cover dynamics in Chiang Mai city and its surrounds. The land-use and land-cover statistics, obtained from GIS data base and satellite images from 1952, 1977, 1989 and 2000 revealed rapid increased in urbanization during these periods. To understand the underlying causes of land-use and land-cover dynamics, remote sensing, GIS and modeling techniques were applied.
