Abstract

Groundwater is a vital resource for domestic, agricultural, and industrial activities, as well as for ecosystem services. Despite this, the resource is under significant threat, due to increasing contamination from anthropogenic activities. Therefore, to ensure its reliability for present and future use, effective management of groundwater is important not only in terms of quantity (i.e. abstraction) but also quality. This can be achieved by identifying areas that are more vulnerable to contamination and by implementing protective measures. To identify the risk and delineate areas that are more exposed to pollution, various groundwater vulnerability assessment techniques have been developed across the globe. This paper presents an overview of some of the commonly used groundwater vulnerability assessment models in terms of their unique features and their application. Special emphasis is placed on statistical methods and overlay-index techniques. The assessment of the literature shows that statistical methods are limited in application to the assessment of groundwater vulnerability to pollution because they rely heavily on the availability of sufficient and quality data. However, in areas where extensive monitoring data are available, these methods estimate groundwater vulnerability more realistically in quantitative terms. Many works of research indicate that index-overlay methods are used extensively and frequently in groundwater vulnerability assessments. Due to the qualitative nature of these models, however, they are still subject to modification. This study offers an overview of a selection of relevant groundwater vulnerability assessment techniques under a specificset of hydro-climatic and hydrogeological conditions.

Abstract

Re-delimitation of rainfall regions plays an important role in determining the rainfall pattern of an area. This study aims to reconstruct the delimitation of rainfall regions for the western region of Peninsular Malaysia. This study involved only the collection of rainfall data at 133 stations from 1960 to 2010. These data were obtained from the Department of Irrigation and Drainage, Malaysia. The analysis methods applied include kriging, contouring and topology using a geographical information system. The results showed that the new delimitation of the western region has been formed with an area reduction of 10% compared to the original western region found by Dale. This is due to some areas in the western region have not received rainfall between 2540 and 2794 mm. The area that getting the rainfall between 2540 and 2794 mm is 46,413.6 km2, in contrast to the sized of Dale’s western region of 51,596.2 km2. The area that frequently getting rainfall of between 2540 and 2794 during 1960s to 2010 are Parit Buntar, Taiping, Kuala Kangsar, Ipoh, Teluk Intan, Tanjong Malim, Batang Kali, Cameron Highlands, Subang, Petaling Jaya, Klang, Kajang and Bangi. The new delimitation formed through this study can be used as a guide by the agencies that manage water resources in Perak, Selangor and Negeri Sembilan in planning a more efficient water supply system.

Abstract

The article reviews one of the important problems of water usage – operational management of irrigation. The article discusses a methodological approach to the estimation of economic efficiency of water usage in the conditions of climate change in the territory concerned. So far, there has not been a simple method to determine this indicator. When assessing climatic conditions, taking into account their influence on the productivity of agricultural crops, it is necessary to take into account meteorological factors that have a decisive influence on the development of agricultural crops and, accordingly, determine their yield. These include primarily heat and moisture. Moreover, it is necessary to take into account their possible negative influence on the development of plants, considering that for each crop a certain optimum regime of temperature and soil moisture is required in different phases of its growth. To assess climatic conditions taking into account the potential crop productivity, we can use the CPA formula. Calculations have shown a close relationship between the CPA and the yield of agricultural crops. Correlation coefficients of the obtained bonds vary from 0.85 to 0.98 depending on the culture and the territory.

Abstract

The article is based on the assumption that discourse plays a key role in constructing social reality. This also applies to ableism, i.e. discrimination against people with disabilities: the forms used to talk about this phenomenon shape its image and real relations within society. Inclusive language represents an attempt to counter ableism at the level of discourse. This text aims to analyze selected lexical units of Italian considered inclusive and demonstrate their weaknesses in preventing the exclusion of people with disabilities.

Conceptualizations of writing in Polish and South African language curricula for grades 4–8 and 4–9

Abstract

This study aims at exploring the conceptualisations of writing in the language-oriented Curricula of Polish and South African education in Grades 4–8 and 4–9, respectively. Using Ivanič's model we show how writing is framed in literacy education in Poland and South Africa. The findings suggest in general that curriculum developers in both countries tend to view writing as a set of genres and skills. Comparisons made between Polish and South African curricula reveal some differences both in conceptualising writing and in the presence of discourses of writing. In comparison to the Polish curricula, the South African ones are much more detailed, which what can mainly be traced back to their different formal structure. Nevertheless, implications for policy and curriculum development in both countries include a need for greater consideration of the complexities of writing.
