AbstractMost natural hazards can be dealt with be measures involving avoidance or prevention, the causes of such hazards being relatively well understood so that identification and prediction (admittedly not in absolute terms) can be made. Nonetheless in many parts of the world, the response to natural hazards by means of risk evaluation and consequent land use planning is lacking. Many methods are available to evaluate the risk which potential hazards present. The results can be used to produce hazard-risk maps. It could be another generation or two before there is enough user generated feedback to help establish a model for mapmakers to follow.

Direct Applicability

AbstractMaps and plans represent essential tools of the trade for planners and applied earth scientists alike, and thematic maps produced by geologists should be able to be understood by planners. Geology, geotechnics, geomorphology, hydrogeology and related sciences can provide essential data on some of the constraints to development and resources for development. Recognition of these permits safer, more cost- effective planning and development, and allows rational decisions to be taken as far as the exploitation of resources is concerned. Consequently the Department of Environment had been commissioning research to investigate the best means of collecting, collating, interpreting and presenting, in sets of maps and reports, geological results of direct applicability to land-use planning. For example, some years ago initial studies in thematic mapping were undertaken by the British Geological Survey and more recently a number of private consultants have carried out such work. Unfortunately, the results of some of these surveys have not, as yet, been published.

Karst features such as polje are highly vulnerable to natural and anthropogenic pollution. The main objectives of this study were to investigate the soil quality in the Ioannina polje (north-west Greece) concerning arsenic (As) and zinc (Zn), and delineate their origin as well as compare the As and Zn content in soil with criteria recorded in the literature. For this purpose, the geomorphological settings, the land use, and the soil physicochemical properties were mapped and evaluated, including soil texture and concentrations of aqua-regia extractable As and Zn. The concentration of elements was spatially correlated with the land use and the geology of the study area, while screening values were applied to assess land suitability. The results reveal that 72% of the total study area has a very gentle slope. This relief favors urban and agricultural activity. Thus, the urban and agricultural land used cover 92% of the total area. The spatial distribution for As and Zn in the soil of the study area is located on very gentle slopes and is strongly correlated with the geological parent materials and human-induced contamination sources. Arsenic and Zn can be considered enriched in the soil of the area studied. The median topsoil contents (in mg kg−1) for As (agricultural soil 16.0; urban soil 17.8) and Zn (agricultural soil 92.0; urban soil 95.0) are higher compared to the corresponding median values of European topsoils. Land evaluation suitability concerning criteria given from the literature is discussed. The proposed work may be helpful in the project of land use planning and the protection of the natural environment.

The main problem faced by sloping lands in the humid tropic includes land degradation influencing natural ecosystem damage broadly. Land conversion and improper land-use have been widely recognized as the main cause of environmental damage since the demands for agricultural lands become greater than land resource available. The objective of this study was to determine the concept of appropriate land-use planning through environmentally sound spatial management in order to prevent land and environmental degradation.  The sub-district of Antang Kalang was chosen as study area representing sloping lands in humid tropic that have a susceptibility to erosion. Conservation approach by the use of USLE erosion risk prediction model and land evaluation through land suitability classification was used in this study. The geographic information system (GIS) and remote sensing (RS) technology were applied to generate spatial basic information and to assist in spatial analysis. Two crops, upland rice, and rubber,  representing food crop and estate p have been selected based on the local resource that has been existed since a long time ago. The result of spatial analysis shown that the arable land for agricultural practices covers  9,039 hectares (23.19%) while for non-arable land, it is allocated for forest preservation with total areas 29,934 hectares (76.81%). Land-use planning and land resources management involving conservation aspect and land suitability evaluation should be taken into account for farming practice at sloping lands areas since the value of soil loss potential appears as an indicator of erosion risk. Permanent cultivation system and the intercropping farming system is the option of recommended agricultural practice at sloping lands in the humid tropic that have a susceptibility to erosion.

In this research, the integrated model of GIS and decision tree (DT) was built for land suitability analysis that support the foundation of land use planning. GIS was used to create thematic maps and decision tree shows several factor combinations according to plant average productivity. This study is applied for coconut trees in Mo Cay Nam district, Ben Tre province. The target variable is the productivity and the predictor variables consist of soil types, salinity, acidity, flood and irrigation. The study shows that the interpretation level of the predictive variables is 99.09%. The area of highly suitable is 3,522.22 hectares, suitable is 12,376.21 hectares, moderately suitable is 6,309.37 hectares.

Natural conditions of certain area imply to the complex influence of various elements of the environment (surface, relief, climate, water, vegetation type) and man, and knowledge of their recent state represents basis of an integrated approach in the land use planning. Analysis of natural conditions and processes in the Serbian-Macedonian border area is usually done through the valorization of natural potentials, but aspect of their limiting influence on the development of this territory - natural hazards assessment has remained unresolved. Degree of natural hazards vulnerability of a certain territory is an important factor in land use planning, because it represents a threat to the undisturbed development of a certain teritory. The basic idea of this paper is to provide multi-hazard assessment and the integral map of areas vulnerable to various types of natural hazards in Serbian-Macedonian border area. In this way seclusion of areas where natural conditions can represent the limiting factor for the development of the analyzed territory shall be performed.
