Abstract

The study covered water resources of two mountain streams in the Polish Carpathians. These were the Biała Woda and Czarna Woda streams, the catchments of which are adjacent to each other. Water flows in both streams were measured during the hydrological years from 2006 to 2020. Next, water outflows from the catchments were calculated. The study aimed to determine differences in the water resources of those catchments in a very small mountainous area. The study showed quantitative similarity in water resources in the entire multi-annual period but at the same time large differences in shorter periods. Instantaneous and daily outflows showed the largest differences, but differences in annual outflows of up to 20% were also recorded. Therefore, hydrological data from operational cross-sections to assess water resources of neighbouring uncontrolled watercourses should cover multi-annual mean values. It was found that during periods of increased runoff (from melting snow or precipitation), the outflow from the Biała Woda catchment was much larger, while during rain-free periods, the outflow from the Czarna Woda catchment prevailed. All short- term flood like outflows were at least several tens of per cent higher in the Biała Woda catchment. The higher retention capacity of the Czarna Woda catchment can be attributed to the land use (mainly forest areas). The results can be used for modelling catchments of similar parameters and determining their retention capacity.

Abstract

Challenges with respect to potable water supply in Vhembe District threaten the health and welfare of local community. This paper is aimed at assessing the challenges and residents’ coping strategies to improve the potable water supply systems in rural areas in Vhembe District Municipality (VDM). Data for this paper was collected from households, councillors, traditional leaders and municipal officials through questionnaires, interviews and focus-group discussions. Qualitative and quantitative research methods were used and thematic content analysis and descriptive statistics were used to analyse data. The results showed that the main sources of water are ground water from boreholes which are used by about 45.3% of the communities, followed by tap water from the dams, by 35.3%, then rivers by 4.0%, fountains by 5.4% and water tankers by 10.0%. Among the identified challenges are: aged water infrastructure, system breakdowns, lack of funding, vandalism of infrastructure and lack of maintenance, operation of infrastructure by unskilled technicians, theft, and non-payment of water services, among others. To cope with water supply challenges, the study recommended that communities play active role in water projects which would include paying of water supply service for its sustainability. They should also play active roles in water committees that will manage, operate and maintain the water supply with the assistance of VDM officials. It was concluded that the rural water supply situation can be improved when communities, government and other relevant stakeholders cooperate and provide solutions and resources.

Abstract

Manuel de Lima (1915–1976), violinist, painter and music critic, began his writing career in 1944 with the long short-story Um Homem de Barbas [ A man with a beard]. It was the middle of the Second World War and the Salazar dictatorship was well established in officially neutral Portugal. A few years before the belated emergence of Portuguese surrealism, to which he was linked, and in the midst of the development of neorealism, a protest movement followed mainly by the young writers of the time, Manuel de Lima asserted himself from the outset as a very singular writer. Um Homem de Barba is a narrative of a love triangle that ends with the spectacular disappearance of the three protagonists. In this first work placed under the sign of the absurd, which mixes satire, marvelous, and burlesque and in which, according to Almada Negreiros' 1944 preface, the author uses realism to "undo realism", we will study the place and role of humor, as well as the various devices used.
