The shortage of water resources in the Northern territory of China and its mitigative countermeasures
China ; Conflict ; Environment ; Northern China ; Water ; Water management ; Water needs ; Water resources ; Water use
The shortage of water resource and large scale exploitation of groundwater have caused a series of environmental problems. The aims of mitigative countermeasures are mainly at developing water saving agriculture and industries, strenghtening water
resources management and reallocating water resources between different regions.
Fog : a possible solution to rural water problems ?

Acute watershortages are experienced regularly in many areas. It is thus of the greatest importance to identify other sources of water in these regions. Fog is one such new source of fresh water and shows a significant potential for use
as a domestic water supply, notably the South African Fog Water Project. - (AJC)

In this paper, the existing major problems on transboundary waters in different sub-regions of Asia, such as watershortage, transboundary waters pollution, fragile eco-environment are discussed. China has 19 major international rivers and has been
faced on complicated transboundary water and eco-security issues.
volume united with strong evapotranspiration lead to abnormally high watershortages. It is pointed out that this climatic situation is linked up with great changes in the general circulation of the atmosphere over the nearby Atlantic and Europe. Having
With the knowledge in mind that every drought is a result of a persistent upsetting of the water balance, an inventory of the available climatic data was made to determine the intensity of the 1976 drought. The analysis of this study brings out
an unusual run of more or less deficient months ending up during the Summer, in an exceptional situation, mainly in the northwest of our country, where the rain shortages sometimes exceed 60% for the period December 1975-July 1976. The anomalies in rain

of the key factors which make these lakes so distinctive. During periods of low precipitation, watershortages occurred in the lakes, especially Pniówno and Syczyńskie. The Łeczna-Włodawa Lakes are commonly distinguished, among other Polish water bodies
, the lakes in question constitute a distinctive group among the Łeczna-Włodawa Lakes. They are located in the borderland of the Cretaceous Chełm Hills (part of the Polish Uplands) and Polish Lowland. The quantity of the underground water supply was one
, as super-passive due to their water flushing time (>10 years). However, the average flushing time of the water in lakes Tarnowskie, Chuteckie, Pniówno and Syczyńskie, based on the underground supply, amounted to 606, 211, 54 and 79 days, respectively
Socio-economic factors influencing sustainable water supply in Botswana

Botswana is concerned with watershortages which may hamper people's basic needs and industrial development in the future. Other sustainability concerns relate to the environment (pollution), social factor (equity and affordability) and economic
considerations (cost recovery and efficiency). Prices, costs and the value of water are instrumental in striking a compromise between these goals. Trends in pricing and their relationship with costs and resource value are presented, and the impact of prices
and subsidies on water demand and supply reviewed in order to assess their contribution towards a sustainable equilibrium.

The article deals with the Arenosol (sandy soil), the tropical soils, groundwater, water pollution, water supply in Mozambique, East Africa. In the region of the city Xai-Xai in southern Mozambique the population increased strongly. The consequences
of this aspect are the clearing of the wooded dune systems and the pollution and shortage of groundwater resources. - (IfL)

The rice fields have spread during last years at the mouth of the Guadalquivir river, in a marshy area. The chronic watershortage, the conflicting relations with the surrounding parklands and the lack of social cohesion are the main problems

A reevaluation of the usual view that shifting cultivation leads to forest degradation, soil erosion, watershortages, and other undesirable changes. Author examines the swidden farming near three upland villages in northern Thailand. swiddens
. It also experiences difficulties of land and watershortage, environmental deterioration and congestion. Remedies suggested are: restructuring of the urban hierarchy, redistribution of industrial establishments, improvement of techniques, suburbanization
