Chennai, the capital city of Tamil Nadu State, India is the fourth most populous metropolitan city in the nation, and the world's 36th largest metropolitan area. This city is facing acute water scarcity since it depends mainly on the North East monsoon (October-December) rain. As per the WHO norm of domestic water supply along with 20% of domestic use for industrial purpose, Chennai needs 807 million litre per day (MLD) for the present 4.98 million people and 1,455 MLD in 2050 for the 8.98 million projected population. There is about 2,018 MLD of water by different sources to the city. However, the dependable water resource from to this city is only 730 MLD and hence the present deficit is 77 MLD and 725 MLD in 2050. However, through ‘Urban resilient’ integrated water resources management pathways, it is possible to generate or save about 4,225 MLD of water to this city and bridge the water supply demand gap.

<p>Uneven distribution of water resources in the face of climate change and population growth is imposing increasing threats to communities as well as challenging decision-makers. Inter-basin water transfer (IBT) schemes have been appreciated as one of the common approaches to tackle this issue. This work presents a framework for climate impact assessment and feasibility study for IBTs. The framework investigates negative impacts of IBTs on the donor and receiving bodies. This is done by calculating hydrological drought risk and environmental risks to freshwater habitats under 1200 future climatic scenarios and two different transfer scenarios. 2.2 Km resolution time-series from UK’s Met Office most recent climate projection (UKCP18) is used as the input scenario and a water resources model developed at Newcastle University is implemented to determine allocation and calculate the above risk factors. This work considers transferring raw water from England’s water-rich North East to its water-stressed South East as the case study. This case was chosen because England, with no major IBT scheme, is experiencing challenges from more frequent climate change and increasing demand for water in London. Additionally, organisations such as National Infrastructure Commission (NIC) and Environment Agency (EA) have encouraged England’s water companies to consider IBT as one of the options to improve water supply resilience. In this study, we assess schemes to transfer water using the existing infrastructures of water companies located from North East to South East of England to minimise costs and environmental impacts. Results suggest that, under a wide range of future scenarios, meeting London’s annual water shortage through transfers from the North East during wet season of each year not only increases London’s water supply resilience but also boosts flood resilience in the North East donor basin while still meeting environmental requirements.</p>

The People

The Ruhr, with an average flow of 80.5 m3/s at its mouth, is a comparatively small tributary to the Rhine River that has to perform an important task: to secure the water supply of more than 5 million people and of the industry in the densely populated region north of the river. The complex water management system and network applied by the Ruhrverband in the natural Ruhr River Basin has been developed step by step, over decades since 1913. And from the beginning, its major goal has been to achieve optimal conditions for the people living in the region. For this purpose, a functional water supply and wastewater disposal infrastructure has been built up. The development of these structures required and still requires multi-dimensional planning and performance. Since the river serves as receiving water and at the same time as a source of drinking water, the above-standard efforts of Ruhrverband for cleaner water also help to conserve nature and wildlife. Ruhrverband has summed up its environmental awareness in the slogan: “For the people and for the environment”. This basic water philosophy, successfully applied to the Ruhr for more than 80 years, will be continued in accordance with the new European Water Framework Directive, enacted in 2000, which demands integrated water resources management in natural river basins, by including the good ecological status of surface waterbodies as an additional goal.

Parameter Values

Key sources of uncertainty of importance for water resources management are (1) uncertainty in data; (2) uncertainty related to hydrological models (parameter values, model technique, model structure); and (3) uncertainty related to the context and the framing of the decision-making process. The European funded project ‘Harmonised techniques and representative river basin data for assessment and use of uncertainty information in integrated water management (HarmoniRiB)’ has resulted in a range of tools and methods to assess such uncertainties, focusing on items (1) and (2). The project also engaged in a number of discussions surrounding uncertainty and risk assessment in support of decision-making in water management. Based on the project's results and experiences, and on the subsequent discussions a number of conclusions can be drawn on the future needs for successful adoption of uncertainty analysis in decision support. These conclusions range from additional scientific research on specific uncertainties, dedicated guidelines for operational use to capacity building at all levels. The purpose of this paper is to elaborate on these conclusions and anchoring them in the broad objective of making uncertainty and risk assessment an essential and natural part in future decision-making processes.

Two Factors

The quality of elementary education plays a critical role in an individual’s growth. Thus it has the capacity to develop a nation’s human resources. This study has examined the capabilities of young students who enrolled at the elementary level in schools located in India’s rural areas and their proficiency in different subjects, specifically their own regional language, mathematics and their knowledge of English. In order to measure the performances of students enrolled in Classes 1–VIII, the study used the principal component analysis (PCA) on original, 12 correlated variables. A standardised regression score of two factors, generated from PCA, was used to measure the status of education at the elementary level for different states. By considering the total score of two factors, using the PCA, it was found that most of the states in the southern parts of the country, that is, Kerala, Andhra Pradesh, Telangana, Karnataka and Tamil Nadu, and the North-East region, that is, Assam, Mizoram, Tripura, Sikkim, Meghalaya, Nagaland and Arunachal Pradesh, exhibited better academic performances as compared to other states.

Increase in quantity of population, development of industry and agriculture has created a systemic growth of demand on water. Despite the fact that Georgia is rich in natural water resources having high quality drinking properties, in many regions and, especially, in semi-arid and humid zones, the problem of supplying the population with clean drinking water is quite acute. The article is about the issue of utilizing the waters formed in the River Cheremiskhevi bed for prospectively supplying with water the villages (Village Velistsikhe, Village Zegaani, Village Mukuzaani) in Gurjaani municipality situated on the North-East slope of Tsiv-Gombori Ridge. With this purpose, in 2013-2020, the chemical and sanitarymicrobiological characteristics of the filtrate waters in alluvial-proluvial sediments and surface (river) runoff of the River Cheremiskhevi were studied in field and stationary conditions.
