Since land resource database development in 1987/1988, a large amount of digital data in spatial, tabular and metadata format has been collected and generated. There are some application softwares of soil database to manage such a large amount of data, i.e.: Side & Horizon (SHDE4), Soil Sample Analysis (SSA), and Land Unit in dbf file, while Site and Horizon is in DataEase formats. The database...

combustion flue gas desulfurization (FGD) using lime or limestone are the primary processes employed to reduce sulfur dioxide (SO 2 ) emission from coal combustion. However, these processes generate voluminous solid wastes, i.e., pyrite and gypsum, that are usually landfilled, occupying thousands of acres of land and creating serious land and water pollution problems due to the release of acids...

Land degradation is recognized as one of the major threats to the buffer zones of protected areas (PAs) in Vietnam. In particular, the expansion of land degradation into the PAs is exerting pressure on biodiversity conservation efforts. This degradation is partially the result of mismanagement: the utilization of the land is often unmatched with the inherent suitability of the land. Identificat...

Abstract Land salinization is a major obstacle to the sustainable development of agriculture in arid regions. The demand for food, fiber, fuel and fresh water has increased in the recent decades, particularly in developing nations, due to alarming rise in population. As fresh water resources and productive lands for crop production are limited, new strategies for the sustainable utilization of ...

Farming households with close kinship ties in northeast Thailand have long been practising joint utilization of farmland. They used this multihousehold farming method even more actively to cope with the macroeconomic development beginning in the 1960s. A 1989 survey of a village by the author found more than one-third of farmland under such communal use. However, the share decreased drastically...

“Given the high land values in central business sections of our leading cities, the skyscraper is not only the most efficient, but the only economic utilization of certain strategic plots. An exhaustive investigation... has conclusively demonstrated that the factors making for diminishing returns in the intensive development of such plots are more than offset by the factors making for increasin...
