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.

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.

Synergi analysis of the tugging of interest  in agricultural production and envirometal services. Conversion of land functions into intensive agriculture can cause degradation or declining land capability. This is because farmers' orientation is always on production and ignoring environmental services. Intensive agriculture always causes environmental problems, resulting in a tug of war in agricultural production and environmental services. The purpose of this study is to find out how much intensive land use has resulted in a deterioration of environmental services. This research was carried out on intensive agricultural land (Horticulture) (PI), AF-CK (cloves), AF-KK (cocoa), AF-KM (candlenut), AF-KP (coffee), owned by farmers and AF-HS (forest secondary) in Tn. Kelimutu National. This research uses interviews and exploration methods. The results showed that the level of intensification of horticultural land use in Kelimutu was classified as very intensive with an R-value and an LUI index = 79, the survey results showed that the density of earthworm populations in SPL-AF was as low as the population in SPL-HS, on average only 3 tails m-2, while in SPL-PI the average is only 0.24 m 2. The earthworm biomass in AF is about 69% smaller than the worms found in SPL-HS; earthworm biomass average in SPL-AF 15 g m-2 while in SPL-HS an average of 47 g m-2; and the smallest worm biomass found in SPL-PI averaging about 2.3 g m-2. The diversity of earthworms is significantly different between land uses. The average diversity of earthworms (H ') reaches 0.88; Index R = 0.34; and Index E = 0.92. The four species that dominate are 1). Pontoscolex (endogeik, INP = 48.52), 2). Megascolex (endogeik; INP 44,61), 3). Pheretima (epigeic, INP 35.29), and 4). Lumbricus (epigeic, INP = 13.01)

Abstract This study was conducted in the Daitu district of Thainguyen, Vietnam during November 2001 to January 2003 to identify and estimate potential areas for aquaculture development in a watershed area by integrating socio-economic and environmental data into a geographical information system (GIS) database. Fourteen base layers were used for land evaluation and grouped into four main land use requirements for aquaculture namely: (1) potential for pond construction (slope, land use type, soil thickness and elevation); (2) soil quality (soil type, texture and pH); (3) water availability (distance to water, water sources and precipitation); and (4) geographical and socio-economic factors (population density, distances to roads, local markets and hatcheries). The study demonstrated the usefulness of GIS modelling to select suitable sites for the development of watershed ponds, and the importance of using the data as a tool for planners to develop strategic plans for aquaculture development. The study indicated that about 4.7% (2,725 ha) of the total land area of 57,618 ha in Daitu district was suitable for watershed pond aquaculture, compared to the existing 404 ha of watershed ponds.

Soil And Water

Erosion in the watershed generally occurs due to land use that ignores the rules of soil and water conservation. There is much activity carried out by people living on land in the Yeh Leh watershed area, which makes the level of dependence is very enormous.The erosion forecast is using the USLE (Universal Soil Loss Equation) to estimate the erosion swift occurs and to obtain illustration in determining the precise soil and water measures in a region. The determination of land capability classification is using Arsyad’s method (1989) in which to classify the land ability by classifying the land ability class based on the value of land limiting factors, which then adjusted to the criteria of classification of land capability. The land use directional determination is applying the scoring method where combining field slope factor, soil sensitivity to erosion and daily rainfall intensity. The erosion level of the YehLeh watershed area is categorized as mild to very severe. A very light erosion level as large as 515 ha (21.01%), with the land use in the form of irrigated rice field and forest. The severe erosion level as large as 990.02 ha (40.40%) with land use in the form of plantations. The very heavy erosion level as large as 945.82 ha (38.59%) with land use in the form of plantations. The classification of land capability in the YehLeh watershed area consists of 5 classes of land abilities: class II of 115, 22 ha (4.70%), class III of 533.95 ha (21.79%), class IV of 423.61 (17.28%), Class VI of 1,102.03 ha (44.97%), and Class VII of 276.03 ha (11.26%), with some limiting factors for instance, soil texture, erosion and drainage. Proposed land use in the YehLeh watershed area use for forest areas is as protected forest of 456.49 ha (18.63%). Proposed land use outside of the forest area consist of 58.51 ha (2.39%) of seasonal crops, annual cultivation area of 990.02 ha (40.40%) and buffer area of 945.82 (38.59%).

Generating land capability class guidelines at a watershed scale has become a priority in sustainable agricultural land use. This study analyzed the area of cultivated land use situated on the non-arable land-capability class in the Jema watershed in the Upper Blue Nile River Basin. Soil surveys, meteorological ground observations, a digital elevation model (DEM) at 30 m, Meteosat at 10 km × 10 km and Landsat at 30 m were used to generate the sample soil texture class, average annual total rainfall (ATRF in mm), terrain, slope (%), elevation (m a.s.l) and land-use land cover (%). The land capability class was analyzed by considering raster layers of terrain, the average ATRF and soil texture. Geo-statistics was employed to fit a surface of soil texture and average ATRF estimates. An overlay technique was used to compute the proportion of cultivated land placed on non-arable land. As per the results of the terrain analysis, the elevation (m a.s.l) of the watershed is in the range of 1895 to 3518 m. The slope was found to be in the range of 0 to 45%. The amount of estimated rainfall ranged from 1640 to 131 mm with value declined from the lower to the higher elevation. Clay loam, clay and heavy clay were found to be the major soil texture classes. Four land capability classes, i.e., II, III, IV (arable) and V (non-arable), were identified with proportions of 28.56%, 45.74%, 22.16% and 3.54%, respectively. Seven land-use land covers were identified, i.e., annual crop land, grazing land, bush land, bare land, settlement land, forestland and water bodies, with proportions of 42.1, 35.9, 8.90, 8.3, 2.6, 2.1, and 0.2, respectively. Around 1707.7 ha of land in the watershed is categorized under non-arable land that cannot be used for annual crop cultivation at any level of intensity. Around 437 ha (3.5%) of land was cultivated on non-arable land. To conclude, the observed unsustainable crop land use could maximize soil loss in upstream regions and siltation and flooding downstream. The annual crop land use that was observed on non-arable land needs to be replaced with perennial crops, pasture and/or forest land uses.
