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.

Bangladesh is a land scarce country where per capita cultivated land is only 12.5 decimals. It is claimed that every year about one percent of farm land in the country is being converted to non-agricultural uses. The study is based mainly on field survey covering 2 villages (Narikel Baria and Baze Silinda) from 10 sub-urban villages around Rajshahi City Corporation under Paba Upazila of Rajshahi district. The study area was selected purposively and the respondents of this research work were selected randomly. The major focus was on to mention the general land use pattern of the area, estimates the agricultural land conversion besides determining the causes and consequences affecting such conversion. Both Narikel Baria and Baze Silinda villages were selected as study area because of its relatively higher growth in infrastructure. In order to fulfill the goal of this study, primary and secondary data were collected from various sources and to analyze and process of collected data the SPSS, Excel and Arc GIS software were used. Different types of descriptive statistics were applied for representing the analyzed data. It is observed that the land conversion form agriculture to non-agriculture allied in recent time is more than the previous time due to gradually increasing land demand in housing and relevant services which invites adverse impact on agricultural land as well as its dependent population. So, it is necessary to take integrated land-use planning to offer better options for the fulfillment of land demand both of housing and agricultural sectors.

Hau Giang is one of 13 provinces in the Mekong Delta. Total land area is 162,171 ha (statistics 2014), agricultural land is 141,217 ha accounting for 87.08 % of natural area. To exploit the reasonable land and provide a scientific basis for adjusting the land use planning to 2020, the evaluation of land resources in Hau Giang was carried out. To apply the land evaluation methodology of FAO to research on natural conditions, socio-economic related to land use to evaluate land resources as well as to apply for geographic information system (GIS) and automatically land evaluation system (ALES) gave results positively, quickly and efficiently. Evaluation results showed that Hau Giang had four major land groups with 11 land mapping units; alluvium land group accounted for 37.26 % of natural area. From the map overlay has been integrated 28 land units. Basing on 44 LUTs surveys was selected for 16 LUTs to have development prospects to evaluate land suitability. Land use was divided into 5 main groups: alluvial land belonged to riverside Hau, slightly saline land was not submerged and was shallow, and low-lying saline land was flooded and saline land was salty. To combine with evaluating the current state of land use, productive techniques and socio-economic development needed supplementing of land use planning by 2020 as follows: (1) agricultural land is 141,217 ha (87.08 %); (2) non-agricultural land is 20,918 ha (12.90 %) and (3) unused land is 36 ha             (0.02 %) of natural area.

Many developing countries do not focus on land use planning in hydropower development. As a result hydropower projects are not sustainable. The aim of the study is to analyze the cause and effects of land use planning in hydropower development. The primary and secondary data were collected in a case study site at the Upper Tamakoshi Hydroelectric Project (UTHEP) in Dolakha district of Nepal. Household questionnaire, key informants? interviews and field observation were conducted to collect primary data while the relevant documents such as detailed feasibility report, property valuation report and spatial data (cadastral data, image etc.) were also collected for the study. The primary and secondary data reveals that Land use changes involved in the UTHEP implementation is basically due to the permanent and temporary land acquisition for project structures, facilities and reservoir area. The total land acquired for various project components like access road, powerhouse, desanding basin, reservoir as well as construction borrow pits and quarries, temporary and permanent work camps and construction of access road is estimated to be 182 ha. The secondary data reveals that 66 ha are allocated in agricultural land, 78 ha in forest land and 38 ha in the barren and cliff land. The results from secondary data and interviews confirm that UTHEP has planned to distribute 10% share to the residents of Dolakha district to promote local level investment. Finally, the study finds that land use planning has very important role for minimizing negative social and environmental effects thus create sustainability of the hydropower projects. It is also found that overall environmental impacts are limited because of technological development such as tunnel and underground powerhouse in UTHEP. The land tenure, Land use planning stakeholders and their role, Governance, policy, social structure etc. are the basic requirements of land use planning for sustainable development of hydropower projects.

Land use planning is an important topic in the view of spatial land management. One of the significant elements that should be taken into account for land use planning includes the availability of land resource information/data. Well-organized data was then required for planning. In the Gunung Mas regency case, the data was available, but it has not been organized properly for land use planning. Land resources information systems should then be developed for planning purposes such as plan formulation and decision making. The objective of this study was to organize land resources information making the information system integrated within a web-based GIS. The general procedure involved data collection and compilation to be organized into a database system. The information system of land resources integrated into web-based GIS can provide a database system. This system can represent graphical systemic spatial or coordinate information in the form of digital maps. Furthermore, the web-based GIS practically facilitates various database operations such as querying, analyzing, and displaying based on location geographically. It can be accessed anytime and anywhere by the planner and decision-maker. The database system integrated into land units can then be used as basic consideration and analysis for land evaluation and the land-use planning process.
