The Cadastral system in Kenya was established in 1903 to support land alienation for the white settlers who had come into the country in the early part of the 20th Century. In the last hundred years, the system has remained more or less the same, where land records are kept in paper format and majority of operations are carried out on a manual basis. The lack of a modern cadastral system has contributed to problems in land administration in the country.

The Huang-Huai-Hai Plain is the most important winter wheat and maize production region in China. In response to the increasing population pressure, the Chinese authorities strongly invested in improving the irrigation systems and increasing ground and surface water exploitation within the plain to increase the crop productivity. This resulted in a reduction of water resource availability and in turn indirectly affected the suitability of various agricultural ecosystems in the plain.

Multicriteria-Spatial Decision Support Systems (MC-SDSS) are increasingly popular tools in decision-making processes and in policy making, thanks to their significant new capabilities in the use of spatial or geospatial information. Many spatial problems are complex and require the use of integrated analysis and models. The present paper illustrates the development of a MC-SDSS approach for studying the ecological connectivity of the Piedmont Region in Italy.

This study was carried out to assess the land suitability for rainfed faba bean (Vicia faba L.) cultivation in Gonbad-Kavous region (Golestan province, north of Iran) using geographic information system (GIS) and analytical hierarchy process (AHP), the most common methods for evaluation of land use suitability. Several parameters were considered in this study, including the annual average, minimum and maximum temperatures, annual precipitation, slope, elevation, and some soil properties such as organic matter, pH, EC, texture, phosphorus, potassium, calcium, iron, and zinc.

The main objective of this research was to compare the suitability of land for surface and drip irrigation methods according to a parametric evaluation system in the plains west of the city of Shush, in south‐west Iran. After analysing and evaluating soil properties, suitability maps were generated for both methods by means of remote sensing (RS) and a geographic information system (GIS). The results showed that 9031 ha (21.5%) of the studied area was highly suitable for surface irrigation methods, whereas 32 500 ha (77.5%) of the study area was highly suitable for drip irrigation methods.

There is a growing need to site new power generating plants that use cleaner energy sources due to increased regulations on air and water pollution and a sociopolitical desire to develop more clean energy sources. To assist utility and energy companies as well as policy-makers in evaluating potential areas for siting new plants in the contiguous United States, an adaptation of a geographic information system (GIS)-based multicriteria decision analysis approach is presented in this paper.

Land suitability analysis is a prerequisite to achieving optimum utilization of the available land resources. Lack of knowledge on best combination of factors that suit production of rice has contributed to the low production. The aim of this study were to determine the most suitable areas for rice crop (Oryza sativa) based on some physic-chemical properties of various alluvial soils in the Gokirmak catchment located on the Sinop-Boyabat district in the Central Black Sea Region of Turkey.

Black truffle (Tuber melanosporum Vitt) is an agro-forest resource with great development potentiality in Mediterranean calcareous mountains. In this study, we analyse the ectomycorrhizal inoculum potential of the soil and the competitiveness of Tuber melanosporum ectomycorrhizas to this inoculum in the different land uses present in a truffle-producing region with the aim of assessing their suitability for establishing truffle orchards. Soil samples collected from forests, croplands and wastelands in El Toro (Valencian Region, Eastern Spain) were used to perform four greenhouse bioassays.

Under discussion is the FAO algorithm modified to estimate the suita-bility of lands and soils for agricultural purposes using the definite LUI index (land unit index). The latter is calculated by rating of soil indices taken into complete account and accepted by FAO, USDA (USA) and the Ministry of Agriculture in the Russian Federation. The algorithm and proposed computer programs of interactive expert systems ((ADAPTER, LAND, PLANT) are universal and make it possible to use the indices for solving a number of intricate tasks in off-line regime.
