This chapter sought to assess sector-based current water use levels in Sanyati catchment, assess a possibility of new ways of managing the catchment water using inter-basin transfer systems, and assess future water demands projection using WEAP model. The study was both quantitative and qualitative in nature. Interviews and observations were the main primary data collection instruments. Findings showed that the main sectors and institutions that utilised water in the catchment were mining, agriculture, manufacturing industry, and local authorities. Local authorities and farming sectors were the major users of water. WEAP model results showed a steady increase in demand for water as a result of both population growth and agricultural activities water demand. The study mapped possible inter-basin transfer routes and recommends water harvesting as part of development and management in Sanyati catchment to address the problem of water shortage.

Water Supply And Demand

Beijing is facing the considerable challenge of water shortage, as it is just able to meet current water demand in a year with average precipitation and a shortfall between water supply and demand is estimated to be around 1.8 billion[109] cubic meters (BCM) by 2010. Aiming to find the solution to such a severe challenge, this paper investigates Beijing's current and future water resources availability and water-use configurations, as well as past and current effort on both areas of water supply and demand. The analysis shows a continuously growing demand for water and an aggravating deficit of traditionally available water resources. The paper concludes that it is necessary to establish well-structured water-use data and employ more advanced forecasting methods if sound future decisions regarding water balance are expected to be made. In order to realize Beijing Municipality's full urban water conservation potential, it is suggested that a comprehensive and integrated long-term conservation program be implemented, which is technically feasible and economically justified, to conserve water consistently for many years.

Purpose – The opportunities that the emerging markets present to the players in the construction industry means that the players need to expand on the scope and size of their responsibilities and duties to the stakeholders. Each of the professionals now demands more specialised and sophisticated services from one another. The other players in the construction industry now require more emerging responsibilities and duties from the quantity surveyors. The purpose of this paper is to examine the roles that “modern” quantity surveyors play by measuring the gaps that exist in the services that the quantity surveyors provide. Design/methodology/approach – Primary data are collected through survey questionnaires. In total, 23 roles played by modern quantity surveyors are identified and addressed to the respondents to rank the rate at which quantity surveyors provide these “emerging” services. The collected data were analysed statistically. Findings – The results of the findings led to the conclusion that the quantity surveyors were not meeting the expectations of other players. Therefore, for competitiveness, quantity surveyors need to better meet demand expectations. Research limitations/implications – This findings of this research are constrained to the services or functions that the quantity provide in the construction industry. Practical implications – This knowledge is valuable to academic institutions that offer quantity surveying programmes, to practicing quantity surveyors, governments, and other players in the construction industry. It will allow quantity surveyors to reconcile supply and demand expectations. Originality/value – There is no known conclusive empirical study on services offered by quantity surveyors in any emerging markets. Therefore, the findings offer a fresh understanding on the services of quantity surveyors not only in Nigeria but elsewhere. While some of the services are common, others are peculiar to emerging markets.

Purpose – The purpose of this paper is to analyze the main motives of investors in allocating their money in a socially responsible (SR) way. Design/methodology/approach – The paper is based on primary data collected in a survey using an online questionnaire. This paper applies tests for continuous and categorical data and (ordered) logit models. Findings – In a multivariate analysis that investigates determinants of SR investing, this study finds little influence of the demographic factors of gender and investment volume and none of educational level. Furthermore, it shows that the regions investors allocate their money to are significant along with the preference toward the order of return, risk and liquidity. Moreover, there appears to be a gap between supply and demand of SR investments. Additionally, there are indications that a very important inducement for SR investing is the expectation of a high financial performance. Originality/value – There are very few international studies concerning the link between SR investments and the explanation of preferences with factors other than demographic ones. This study broadens the scope of the literature by providing novel empirical evidence for the German-speaking market.

Cutting is the process in which goods or garment material are cut and converted into pattern shapes of the goods or garment components. There are two methods of Leather cutting, which are hand cutting and machine cutting. Hand cutting is done with the use of hand knife, cutting board and cutting patterns. Machine cutting can be done using semi-automatic cutting machines or fully-automatic cutting machines. Currently, in Ethiopia, different local and foreign investors are participating in leather products manufacturing. Most of the leather product manufacturing industry and some Small and Medium enterprise’s (SME’s) in the country are using leather cutting machines in order to cut leather goods or garment parts. Most of the industry and SMEs are using imported cutting board made of plastics and rubbers. However, these cutting boards are expensive.   This research aimed at developing a cutting board made from HDPE (High-Density Polyethylene) plastic waste as main material, calcium carbonate as a filler and glass fiber as a reinforcing material. Primary and secondary data gathering techniques were applied simultaneously. Primary data were collected through interview and field observation. Secondary data was gathered by reviewing different literature. The cutting board developed through collecting HDPE plastic waste, washing, shredding and melting the shredded plastic with filler and reinforcing material. The melted plastic poured in to cutting board mold and cooled. The developed cutting board was compared with HDPE cutting board available in the local market. The developed board showed relative compression and hardness properties with the HDPE cutting board available in the market. In the cost analysis, the developed cutting board is cheaper than the cutting board which available in the market. However, the cutting board in the market has better surface texture and quality than the developed cutting board. Melting HDPE plastic waste using metal or clay cooking pots and charcoal fire is a tedious task and smoke from the fire will cause human health problem and will affect environment. Consequently, manual plastic melting method is not feasible for mass production, because it is difficult to control the amount of heat (charcoal fire) during melting process. Based on this the authors recommend using machine based plastic melting and molding during HDPE and related plastic recycling.

  Water is of basic substance for Human development, the water brought environment, economy, civilization, livelihood provisions and well being for the society. Comprehensively understanding factors affecting the availability of water for household the water consumption behavior are required to be designed for efficient and effective water uses. To address the issue we randomly investigated 200 households in five different populated towns of Quetta city. The primary data was collected through household questionnaire survey and observation. On the other hand, secondary data included books, journal articles and websites. Data were analyzed using the Statistical Package for Social Science (SPSS). The findings of this study revealed that type of family, monthly income, major source of water, presence of garden at household and responsible factor of water shortage are significantly correlated with water availability. The survey concludes that the available water resources provided by the government are not enough for the daily household usage resultantly the respondents struggle hard to managed alternative water resources as per their requirement. The paper recommend to bring  awareness for the public sector about their right to water and provision of water sources is core responsibly of Government, especially to draw a policy for new constructions of water resources or by the remodeling of water and sanitation systems.

This chapter provides a critical analysis and evaluation of the water issues relevant to Kenya's ASALs. This has particularly been centred on the current resource development and management, future resource demand as well as extent of its vulnerability to climate variability and change. The water development policy interventions have also been evaluated. The analysis has revealed that water resources are being utilized to satisfy a myriad of demands and that in-fact a water shortage already exists in these ASALs. A number of factors including population pressure, poor resource use and management and other socio-economic activities have been noted to increase the vulnerability of the available water to the impacts of climate change. A raft of recommendations for purposes of ensuring the sustainable utilization of this vital resource has therefore, been proposed.

Purpose This paper aims to examine three of the major issues relating to the welfare of seafarers, including wages, social security benefits and onboard and ashore welfare facilities and services. It is impossible to research all countries here, so this paper selects Greece – which is one of today’s primary shipping countries as for shipowning, as well as for global supply and demand for seafarers – to conduct an empirical case study. Design/methodology/approach Based on the existing knowledge and scholarship, and primary data collected in several phases of fieldwork, this paper intends to critically examine three major issues relating to the welfare for Greek seafarers, namely, wages, social security benefits and onboard and ashore welfare facilities and services. Findings This paper finds that they face poor labour conditions, which are getting worse due to the depressed world and Greek economies and intense financial pressures on shipping companies. The entry into force of the Maritime Labour Convention 2006 has a significant impact on the world maritime industry. Research limitations/implications This paper critically examines the three major issues relating to the welfare of Greek seafarers. Originality/value Such issues, which Greece is facing are also common in other countries, so the findings and suggestions revealed from this paper are of importance for the global shipping industry and other states.

Increasing Demand

Currently, water demands are increasing notoriously, spreading the pressure on available water resources around the world in both quantity and quality. Similarly, the expected reduction of natural water inputs, due to climate change, depicts a new level of uncertainty. Specifically, Southeast Spain presents water scarcity due to its aridity—irregular and scarce precipitation and high evapotranspiration rates—combined with the competition between several water demands: environment, agricultural dynamics, urban-tourist activities, and industry. The study area of this work is the most relevant functional urban area of Alicante province (SE Spain), where the administration of water management is carried out by a range of authorities at different levels as the consequence of a complex historical development of water governance schemes: at the national, regional, and local levels. This study analyzes 21 municipalities and proposes a conceptual model which was developed by including different origins of water inputs—surface resources, groundwater, desalination, wastewater reuse, or interbasin transfers—and water demands with information obtained from 16 different sources. Our main results denote a relevant water deficit of 72.6 hm3/year even when one of the greatest rates of desalinated water and reused wastewater in Europe are identified here. This negative balance entails restrictions in urban development and agricultural growth. Thus, presented results are noteworthy for the water policy makers and planning authorities, by balancing the demand for water among various end users and providing a way for understanding water distribution in a context of scarcity and increasing demand, which will become one of the most challenging tasks in the 21st century.

Response To Water

Abstract Water is seen as key factor for development. Its scarcity raises concerns at all scales. In regards to water resources, Annaba and El-Taref are intimately connected, the different activities (groundwater and superficial), focused on increasing supply, have been considered as a response to water demand. The actual system use of water resources is not able to sustain water needs that are more and more growing in different expansion sectors. Consequently, a strategy should therefore be sought to integrate the various sectoral needs in available water resources in order to reach the economic and ecological sustainability. We will try to respond to this problem by use of Water Evaluation and Planning (WEAP) model. This study is the first attempt to estimate water demand and analysis of multiple and competing uses of hydro-system in Seybouse’s Wadi basin and to make comparison with proposed water storage estimates. This model was applied according to five different scenarios which reflect the best and worst conditions of the supply and demand, not only to evaluate water demand deficit, but also to help planners to the alternative management. The model stimulation showed that the area study is sensitive to a serious water scarcity by 2030. It is possible to observe an improvement with integration of other management strategies for a best operating system.
