Journal Articles & Books
December, 2010
Romania

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.

Comparison between land suitability and actual crop distribution in an irrigation district of the Ebro valley (Spain)

Policy Papers & Briefs
December, 2008
Spain

The present research aims to obtain a better insight into the agreement between land evaluation results and actual crop spatial distribution by comparing biophysical land suitability with different crop frequency parameters and with crop rotations derived from multi-year crop maps. The research was carried out in the Flumen district (33,000 ha), which is located in the Ebro Valley (Northeast Spain). Land evaluation was based on a 1:100,000 soil survey according to the FAO framework for the main crops in the study area (alfalfa, winter cereals, maize, rice and sunflower).

Climate change and land suitability for potato production in England and Wales: impacts and adaptation

Journal Articles & Books
December, 2012

The viability of commercial potato production is influenced by spatial and temporal variability in soils and agroclimate, and the availability of water resources where supplementary irrigation is required. Soil characteristics and agroclimatic conditions greatly influence the cultivar choice, agronomic husbandry practices and the economics of production.

Land suitability evaluation for brackish water aquaculture development in coastal area of Hormozgan, Iran

Journal Articles & Books

Iran

Land suitability analysis is a prerequisite for successful aquaculture, and site selection affects both the success and sustainability of any aquaculture development. There is an urgent need for appropriate methodology to assist planners for site selection in aquaculture development. Site selection can be viewed as a multi-criteria decision-making (MCDM) problem. The analytical hierarchy process (AHP) is a proven, effective method used to solve problem of site selection.

Development of a land suitability model for saffron (Crocus sativus L.) cultivation in Khost Province of Afghanistan using GIS and AHP techniques

Journal Articles & Books

Afghanistan

In this study, we have attempted to develop a land suitability model for saffron, an agronomic crop, which is economically viable, environmentally bearable and socially equitable at Khost Province of Afghanistan. The objective was to determine different land suitability classes for saffron cultivation using Analytical Hierarchy Process (AHP) and Geographic Information System (GIS). A decision tree was developed encompassing the physical, economic and social criteria.

Edaphic characteristics of olive-tree areas in the Trá-Os-Montes Region (Portugal): a map-based approach

Journal Articles & Books

Portugal

In the Trás-os-Montes Region (Northeastern Portugal), olive tree plantations cover an area of more than 70 thousand ha (near the 6 % of the regional territory), mostly planted and cultivated under traditional non-mechanised cultural systems. It is fully recognised that the olive sector contributes significantly to the regional agro-economy, as well as to the conservation of certain typical landscapes.

Determination and mapping of land suitability classes for agricultural utilization in Ankara Imrahor Valley and its vicinity

Policy Papers & Briefs
December, 2008
Turkey

That was to perform a determination of land suitability classes for agricultural land uses in Ankara Imrahor valley and vicinity with this study. First of all detailed survey and mapping of research area was performed with aid of satellite data and topographic maps then four different soil serials and their fourteen different mapping units were described. For this units, 38 different land uses were describe as their soil and meterological properties and calculated their suitability for this region and determined and mapping their land suitability classes for agricultural purposes.

Optimal siting and size of bioenergy facilities using geographic information system

Journal Articles & Books
December, 2012

Biomass is a geographically dependent renewable resource which can be used for production of fuels and chemicals. This study develops a methodology for determining the suitable locations, optimal sizes and number of biomass-based facilities for a particular region through transport cost optimization which is applied for locating pellet plants in the Province of Alberta. The methodology also includes computation of local optimal size and cost of pellet production considering road network and spatially varied biomass.

integrated approach for studying the land suitability for ecological corridors through spatial multicriteria evaluations

Journal Articles & Books

Italy

Nature conservation is a very important issue in the sustainability assessments and spatial planning context. Knowledge of the suitability of the land to behave as an ecological corridor thus provides very significant input to land-use planning. Nature conservation and land-use planning are by their nature spatial problems.

Land suitability evaluation for development using a matter-element model: A case study in Zengcheng, Guangzhou, China

China

Land suitability evaluation can assist in the efficient use of land resources at a regional level. This is an important issue because of the pressures that an increasing population and economic growth have put on limited land resources. Matter-element theory, which was first put forward by the Chinese mathematician Cai Wen, has shown potential for solving incompatibility problems.

Vegetable production has an increasing importance in most of the Asian countries. The leader in production per capita is China followed by South Korea, North Korea and Vietnam. In Vietnam, vegetable production is at the moment on 4th place of all agricultural commodities. In the past, in Vietnam as in other South-East-Asian countries, the production of rice, sugar cane, cassava and maize often as monoculture was typical.
