Soil degradation from converting forest land into agriculture in the Chitavan district of Nepal
Soil fertility decreased when forest land was converted to agriculture. But soil conditions under forested land use were not always of the best quality. - (DWG)
In order to highlight the impact of long-term land use on soil quality, the spatial pattern of permanent wetland, permanent forest, permanent dryland, wetland converted to dryland, wetland converted to paddy land, dryland converted to paddy land
, and forest converted to dryland in the Sanjiang Plain from 1979 to 2009 was identified. he Bawujiu Farm, located in Heilongjiang Province, provided a case study for this research project. It is highlighted that agricultural development from wetland decreases
soil fertile status. Dynamics of 8 nutrient indexes of 7 types of conversion are identified. It is recommended that dryland or forest be converted to paddy land because it increases soil nutrient conservation and improvement.
Analyse de la répartition des profits à l'exportation par zone d'origine pour la Fédération de Russie, par zones de devises convertibles et non convertibles, et pour les quatre grandes catégories de produits. L'étude est centrée sur l'identification
des unités au niveau de l'oblast, qui contribuent de façon disproportionnée aux profits totaux de la Fédération en devises convertibles. Ils recherchent les implications de la répartition spatiale extrêmement inégale de ces profits face aux efforts du
Semiology does not inquire into principles in forming the symbols in details, namely for the individual application. Various new symbol may be formed by means of morphographical operation - affixation, congugation, rotation, convertation, mutation
Forty-two railroad stations, many converted to other uses, survived in the San Joaquin Valley up to 1993. Author classifies stations into active Amtrak stops, recycled, and idle. Most of the latter are not architecturally or historically significant
In this paper, the transformation of the Fertöd State Farm (W-Hungary) is presented. During the privatisation process the state farm was converted into a private venture, two thirds of the total land area was sold to smallholders who lease the land
The paper analyses the wind conditions and the location of old windmills on the Great Hungarian Plain, delimiting the areas where the amount of wind power is sufficient to operate wind converters of smaller capacity. - (JS)
The 1982 returns above variable costs on croplands newly converted between 1979 and 1981 are estimated assuming full participation at 1982 price-support levels and market prices.
Deforestation in this region is not recent nor was it the result of peasant ignorance, mismanagement or overpopulation. Rather, it is the Nepalese state that has seen the forest as a convertible, not a renewable, resource. - (DWG)
The role of solar energy in the Hungarian energy structure is considered. The area investigated offers no primary energy sources| it underlines the importance of solar energy. Equipments to convert solar energy are described. (DLO).
for calculating a soil development index by converting the data recorded for site mapping into a scale which shows the degree of development reached by the respective site property. (HL).
a land use and cover type map by classification of the Landsat images, and used the map to study the influence of land use and cover type changes on soil moisture : farmland converted into grassland; grassland converted into farmland; and forest converted
and August monthly precipitation data from Arizona and New Mexico are normalized using a square root transformation, converted into z-scores, and stratified according to onset and following years for Warm Events and Cold Events of the Southern Oscillation.
by a Microsoft Excel tremplate spreadsheet, BAROSURV.XLT, which converts temperature and pressure readings to relative elevations, and graphs the results. Notes on the use of BAROSURV.XLT are included in the ASCII text file BAROSURV.NOT.
