Understanding the pattern of reservoir water quality in relation to morphometry and other landscape characteristics can provide insight into water quality management. We investigated the water quality of 302 reservoirs distributed nationwide in Korea by classifying them using a self-organizing map (SOM), examining how hydrogeomorphometry variables are related to reservoir water quality, and eva...
In order to achieve a sustainable management of land resources and to improve land quality, quantitative assessment of effective factors and soil quality indicators are required. The aim of this study was to evaluate variability of selected soil quality attributes in central Zagros affected by such factors as region, land use and management practices. Twelve sites were selected in three provinc...
Change in land use and tillage practices has great influence on soil physical and chemical properties. The present study has focused on the effects of converting undisturbed soil to agricultural lands. Chemical and physical soil properties, infiltration, cation exchange capacity (CEC), electrical conductivity, pH, bulk density, porosity, sodium, potassium, total Ca + Mg, organic matter percenta...
In this paper we first construct a theoretical model of land use by swidden cultivators when these cultivators can choose whether to grow a cash crop or a food/subsistence crop. Second, we study the land quality accumulation decision faced by shifting cultivators and, in the process, we show how to compute the optimal length of time during which cleared land is to be left fallow. Finally, we in...

18 Land in the southeastern U.S. is expected to change, e.g., given the potential demand 19 to develop forest-to-fuel technologies or, conversely, cropification of current forests to 20 increase food production. Possible future PM2.5 and O3 air quality for two land use/land cover 21 change (LULCC) scenarios, reforestation and cropland conversion, are compared to a 22 reference case scenario for...
Agricultural management systems have been historically adopted without recognizing consequences on soil conservation and environmental quality, and therefore significant decline in soil quality has occurred worldwide. Soil quality has been defined as “the capacity of a specific kind of soil to function with its surroundings, sustain plant and animal productivity, maintain or enhance soil, water...
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...
Under the premise that land administration is one of the necessary components of sustainable development and better land management, this article reviews how progressive titling could foster new land administration procedures and associated information systems. This review is based on the objectives of progressive titling as they are developed or currently implemented in various regions in the ...
