erosion and wind hazard. The main part of the land is under animal husbandry although muchof the eastern part can be used for farming or forestry. Measures are suggested for improvingland use.
The steppe belongs to a transitional belt between the subhumid and semi-arid regions. It is divided into 2 natural zones and 5 subzones and their land use possibilities described. Unfavourable conditions are low temperature, frost, drought, soil
Contribution to theory and realization of permanent land use systems in the humid savannah of Togo
Projects for rural development have to improve small-holders' income. Production-oriented projects in the humid savannah have to initiate the change from extensive to intensive and permanent cultivation methods on a sustainable basis. - (L'A)
Evaluation of land use and river water quality of the Tsukuba mountains ecosystem, Japan
Biogeochemistry ; Ecosystem ; Japan ; Land use ; Mountain ; Statistics ; Water quality
Results of a short term study in late winter and early spring on river water quality of the Tsukuba mountain ecosystem in central Japan carried out at 130 sites. Since it was observed that the river water quality can be maintained or improved
by the presence of natural riverbeds, paddy fields and forests, the protection of these forms of land use should be encouraged.

A survey of households suggests that neither dwelling prices nor rents are high in Manila compared with family incomes. Relatively high land prices have led households to spend much less on structures and to accept low housing welfare although
the availability of skilled construction labour, materials and finance has been fairly good and improving. Household must endure relative settlement insecurity and residential immobility.
Since the reclaimed land is very important for the city, multiple approaches to accelerating siltation are proposed in this paper according to detailed study of dynamics, sedimentary structure and landform evolution based on in situ data
. It is of great significance to utilize tidal flats and reclamation of land in Shanghai.

The arid territory of the USSR covers 266,4 mln. ha. This one is divided into 10 natural regions with regard to the physico-geographical pecularities and types of natural grass lands. Within these natural regions the land types were revealed (arable

The sketch layout model was developed in 1999 to improve the efficiency and quality of layout tasks. This model is a nonlinear and multi-objective programming, for analysing the integrated layouts of land uses, transport network and public
Land-use classification using high resolution satellite imagery : a new information fusion method ; an application in Landau, Germany

This thesis presents an information fusion method for improving the accuracy of land-use classification based on high-resolution satellite imagery. The method integrates spectral, spatial, and structural information existing in the image. It has
The oases environment of arid lands in Northwest China has been improved during recent 40 years, but the general environments out of the oases have been deteriorating. This article discusses the cause and effect of the environmental changes
with the aid of rich data and puts forward countermeasures for eco-environmental protection and improvement.
High levels of regional variability in year-to-year grain yields in the USSR are negatively correlated with national levels of productivy. Despite reasonably good improvements in grain productivity in the west, the Soviet Union continues to suffer
from low and fluctuating levels of national grain production and productivity owing in part to continued dependence on the unreliable wheat lands of the east. The apparently high cost/benefit ratio of investments in these marginal agricultural areas
illustrates the dilemmas the Soviets face in simultaneously achieving improved levels of food availability and agricultural self-sufficiency.
