Opis:
Water related problems are continuously affecting the social infrastructures and jeopardizing the productivity of modern globalized society. As the water crisis intensifies, several governments around the world are advocating a radical solution: the privatization, commoditization and mass diversion of water. Water privatization involves transferring of water resources control and/or water management services to private companies. The water management service may include operation and management, bill collection, treatment, distribution of water and waste water treatment in a community. The privatization of water has already happened in several developed countries and is being pushed in many developing countries through structural adjustment policies. Water privatization will invariably increase the price of this common property resource because there are hidden costs involved in water collection, purification and distribution systems. Increase in water consumption will be satisfied through the market dynamics often at the cost of the poor who cannot afford the increased water tariffs. The corporations will recover their costs by exploiting the consumers irrespective of their economic conditions. Another possible threat of water privatization is the unsustainable water extraction by the water corporations for maximizing profits and subsequent destructions of water bodies and aquifers. Corporations in search of profits can compromise on water quality in order to reduce costs. Privatization can also favour bulk water exports as the control over water will be transferred from local communities to global corporations, which will have disastrous ecological and environmental consequences. Indiscriminate mining of groundwater by multinational companies in Andhra Pradesh, Tamil Nadu and Kerala has resulted behemoth threats to the local water resources, biodiversity and economic structures. Water pricing and privatization will inevitably increase the price of the major crops and vegetables all around the world, which, in turn, can adversely affect the food security of the common people. Community based water management practices like rainwater harvesting, sustainable watershed management, integrated river basin management and irrigation efficiency are sustainable alternatives to water privatization in the third world countries including India.

Opis:
Shortage of water is considered as one of the most important straits of agricultural development in Iran. The main purpose of this study is to determine virtual water used to pea and bean production and water use efficiency, select the best area for cultivating these two grains and find the virtual water budget for the aforementioned grains. The results showed that among the three provinces main producers of pea in Iran, the highest virtual water of pea belongs to Lorestan with 3534 dm3·kg–1 and the lowest belongs to West Azerbaijan with 2660 dm3·kg–1 in irrigated cultivation. Water use efficiency in irrigated cultivation in Kermanshah and West Azerbaijan are at the same level; however, Kermanshah has enjoyed much more level of virtual water. For beans, the highest amount of virtual water in irrigated cultivation belongs to Lorestan (3651 dm3·kg–1) and the lowest amount refers to Markazi (2725 dm3·kg–1) and also the highest level of water use efficiency for this product refers to Markazi. Also it was found that 160.15 mln m3 of water has been exported from the country water resources by these products so virtual water budget for studied crops were negative.
Deficyt wody uznawany jest za jeden z najważniejszych problemów rozwoju rolnictwa w Iranie. Głównym celem badań przedstawionych w pracy jest oznaczenie ilości wody wirtualnej zużywanej do produkcji grochu i fasoli oraz wydajności zużycia wody, wybór najlepszych terenów do uprawy obu roślin i sporządzenie dla nich bilansu wirtualnej wody. Uzyskane wyniki wykazały, że spośród trzech prowincji – głównych producentów grochu w Iranie – największą objętość wirtualnej wody (3534 dm3·kg–1) zużywa się do nawadnianych upraw w Lorestanie, a najmniejszą (2660 dm3·kg–1) – do nawadnianych upraw w prowincji Zachodni Azerbejdżan. Wydajność zużycia wody w nawadnianych uprawach w Kermanshah i Zachodnim Azerbejdżanie była podobna, a uprawy w Kermanshah cechowało większe zużycie wody wirtualnej. Do produkcji fasoli największą objętość wirtualnej wody stwierdzono w Lorestanie (3651 dm3·kg–1), a najmniejszą w Markazi (2725 dm3·kg–1), gdzie stwierdzono także największą wydajność zużycia wody. Obliczono także, że – eksportując te produkty roślinne – wysłano za granicę 160,15 milionów m3 wody wirtualnej, skutkiem czego bilans wodny badanych upraw był ujemny.

Opis:
Drinking Water Supply Service is considered vital in all societies, modern and old. As for all vital services, governance undertakes all possible measures to guarantee their supply continuity. However, severe service supply disruptions may occur under the action of threats, series of failures cascading or any combination of them. Threats may be nature originated: climatic extreme conditions, earthquakes, floods. It may also be man originated: ill-informed managing actions, organisational misconduct or malevolence. As for failures, it can be humans or simply systemic: unproven technology, fatigue, ageing, overloading or operational hazards. Whatever the origins of the disruptions, societies conceive legislations, standards and processes in order to enhance the resilience of the vital service supply systems and the correspondent critical infrastructures. They provide appropriate R&D frames and assets, amongst others, in order to conduct activities on critical infrastructures resilience modelling, simulation and analysis (MS&A). The paper contributes into the development of a resilience concept and a methodology for integrating cascades of failures to help in crisis management decision making. The proposed methodology is applied on a case study belonging to the drinking Water Supply Services and its critical infrastructures.

Opis:
Risk is a basic category to estimate water supply system safety. The first step in risk assessment is to identify the threats and their possible consequences. One of methods for risk assessment is the method using the socalled risk graphs. It relies on the preliminary analysis of such risk factors as: the frequency of threat occurrence – F, the duration of the risk exposure – E, the size of the possible consequences – C and a degree of protection – O, that is inversely proportional to the mentioned measures of risk. The route along the branches of the risk graph should be started from the determination of the initiating/peak event which is the undesirable event (e.g. secondary water contamination in water-pipe network). The expanded risk graph presented in the work differs from the standard (commonly used) graph because it takes into consideration all combinations of the particular risk factors.

Opis:
The paper presents the concept of safety in water distribution systems, which is an important issue connected with its functioning in crisis situations. The research undertaken is directed towards methods of safety assessment relating closely to current world trends, aiming to ensure safety of water supply and use. The paper pays special attention to water consumer safety. Safety levels were assumed on the basis of failure intensity, exposure of water consumers and a number of undesirable event groups. Individual values of the immediate risk index were presented and three categories were distinguished as permissible, tolerable, or unacceptable risk categories, according to presumed action. The risk index can characterize the safety of the functioning of technical systems. The risk index definition is considered as the product of threat ranking. The paper contains the original proposal for a new method of risk analysis and assessment.

Opis:
This work explores ecological and climate-related threats to Afghanistan and discusses support approaches from a European Crisis Management (ECM) perspective. It goes beyond the much-debated troop withdrawal, COVID-19 crisis and peace negotiations and opens an underestimated topic: ‘Climate Change Assistance’. The article aims to advance knowledge on the effects of climate change on human security in Afghanistan and advocates a conflict-sensitive approach. To this end, a climate-related assessment of the human security situation was undertaken and several threat scenarios, options and solutions for enhancing state resilience were developed. The bases for this research were several field trips undertaken by the author since 2004, workshops and an extensive literature review. As a result, it can be stated that the negative impacts of climate change and pollution on Afghanistan’s security and development architecture are massive and make ECM efforts very complex. However, several capacity-building initiatives for military, diplomatic, humanitarian and local stakeholders were identified. On the regional level, this includes the support for early warning systems and hydro-diplomacy with Pakistan, Iran and India. On the local level, the support for community water management and environmental protection matters, while building upon traditional Afghan mechanisms for handling water crises or disasters. Another outcome is the need for more in-depth research in this field as some findings are also useful for other fragile states. The paper argues that there is an urgent need for ECM to respond to the devastating effects of climate change in Afghanistan and identifies several smart opportunities to tackle some root causes of the conflict.

Opis:
The Pogórska Wola palaeovalley of combined tectonic and erosional origin dissects the Mesozoic floor of the Carpathian Foredeep Basin to a depth exceeding 1200 m. It formed during Paleogene times presumably due to fluvial and submarine erosion, concentrated along a local pre-Late Badenian graben system. All members of the foredeep’s Badenian-Sarmatian sedimentary fill attain distinctly greater values inside the palaeovalley than on top of elevated plateaux on palaeovalley shoulders. The fill comprises the Early to Late Badenian sub-evaporite Skawina Formation, the laterally equivalent Late Badenian evaporite Krzyżanowice and Wieliczka formations and the supra-evaporite Late Badenian to Early Sarmatian Machów Formation. Over the plateaux and in the highest palaeovalley segment, the evaporites are developed in the sulphate facies Krzyżanowice Formation, whereas in the lower palaeovalley segments chloride-sulphate facies evaporites of the Wieliczka Formation occur. The rock salt-bearing rocks are involved in thrusting and folding at the Carpathian orogenic front, which helps to assess the lateral extent of the Wieliczka Formation in seismic records. The deep palaeotopographic position of the evaporites inside the palaeovalley, combined with their lithological and sedimentary features, point to their formation via subaqueous gravity flow-driven redeposition of originally shallow-water evaporites, preferentially halite-bearing, presumably combined with precipitation from sulphate and chloride brines at the palaeovalley floor. Both the redeposited sediments and the brines must have come from the adjacent plateaux and from a thrust-sheet top basin, approaching from the south on top of the Cretaceous-Paleogene Carpathian flysch thrust wedge.

Zostały przedstawione warunki, w których SZW może działać jako generator przepływów pieniężnych wprowadzając nowe strategie i tendencje w systemie wewnętrznym państwa. Również zostały przeanalizowane negatywne i pozytywne czynniki rozwoju odpowiednich mechanizmów finansowych. Pod uwagę również został wzięty wpływ kryzysu na rozwój kompleksu – zostały pokazane zarówno negatywne, jak i pozytywne aspekty jego wpływu na SZW.
The article considers how the water management complex (WМC) in its development is affected by financial and economic processes. The peculiarities of the bilateral interaction of the complex and the financial and economic system of the state are analyzed. Economic mechanisms are considered, when using which the WМC complex is a recipient of cash flows. The conditions under which WМC can function as their generator are shown, forming and introducing new principles and tendencies to the internal system of the state. The negative and positive factors of development of the corresponding economic mechanisms are analyzed. The impact of the crisis on the development of the complex is taken into account - both negative and positive aspects of its impact on the chemical industry are shown.
