  • Assessment of Status of Irrigation Practice and Utilization in Western
           Hararghe Zone, Oromia, Ethiopia

    • Authors: Gamachu Ayala
      Abstract: The study was conducted in three selected districts of Western Hararghe zone namely, Mieso, Tullo and Gemechis district with objectives to know the current irrigation practice and utilization of farmers in the area and to identify gaps and constraints of different irrigation practice. Sampling technique was purposive for identifying districts that have high irrigation potential from the zones. From each district, three peasant associations (PAs) were purposively selected each from three traditional agro ecological classifications highland, midland and lowland. A total of 180 households were interviewed and generated both qualitative and quantitative data on constraints, status and practices of irrigation water management. Secondary data were also collected from Zonal Irrigation Development Authority. The data was analyzed using descriptive statistics such as mean, frequency distribution and percentage, were used to analyze data after carefully coded and entered into SPSS V.20 statistical tools. According to the survey result, the mean land holding per household is about 0.78ha while the mean land allocated for irrigation per household is about 0.68ha. Three different types of irrigation were identified; among them Surface irrigation, Pressurized irrigation and water harvesting. While some farmers used combination of surface and pressurized irrigation. Surface irrigation type using furrow method of irrigation is the most common irrigation type in the study area which accounts about 66.5%. The major source of water is from river which accounts about 50%. The major crops cultivated using irrigation in the area were high value crops, about 43.2% cultivated both hot pepper and tomato followed by combination onion, cabbage, red root & tomato by 19.9% and 13% cultivate both onion and tomato as well the left others cultivate different horticultural crops. The study indicated that, water shortage for irrigation, lack improved seed (vegetable crop) varieties recommended for the area, lack of improved technology, diseases outbreak, pest, drought and low price were among major constraints of irrigation practices on the study area. And also there are no transport services because of no road access. In the study area water shortage and lack of improved technology and inputs were the main problem, therefore practicing water harvesting and supplying improved technologies such as seed, controlling diseases, infra structure (road) and providing extension service regularly for farmers should be practiced in future.

  • Determinants of Farmers’ Willingness to Pay for Irrigation Water of
           Lake Hawassa

    • Authors: Teshome Berasso Tule
      Abstract: The contingent valuation method is applied to analyze the economic value of quality improved irrigation water. Based on random sampling technique, 220 sample households were selected to determine farmers’ preferences on how much they are willing to pay for quality improved irrigation water. The Heckman selection model was used to analyze the factors affecting households’ participation in the lake quality improvement and the valuation of the quality improved irrigation water. The valuation result shows that most respondents have reflected their willingness to pay for the lake quality improvement stating their mean WTP of Birr 311.44 for irrigation water per hectare, which is equivalent to US$17.30 per hectare. The analysis on the determinants of WTP shows that education, annual income, multiple uses of the lake, farm size, gender, and age of households are the significant variables explaining the participation in the resource quality improvement and the valuation of the quality improved irrigation water. Therefore, identification of such variables and their relative importance in the valuation helps to obtain households who are willing to pay maximum level for the lake quality improvement.

  • Application of RO System to Desalinate Brackish Surface Water in Southern
           Iraq

    • Authors: Noor Hussein Ali Sabtie, Nagham Nagam O. kariem, Dawood E. Sachit
      Abstract: Brackish surface water desalination is a primary path to relieve the shortage of useable water. The application of reverse osmosis (RO) membrane technology to desalinate the surface water in southern Iraq has recently increased due to the fresh water scarcity for drinking water to meet local needs in this region. Several studies by using simulated brackish surface water which represented the same quality of the water of this region have been conducted. In this study, actual samples of brackish surface water from three locations (Al-Jeweber, Al-Hadam and Al-Masheb) which are, respectively, located in the southern provinces of Iraq (Thi-Qar, Maysan and Basrah) were used as a feed water to conduct several desalination experiments. These feed waters were used to run a pilot scale of spiral wound reverse osmosis (RO) membrane system. The purpose of this research is to study main parameters of RO membrane system as a result of the application of this technology to desalinate the brackish surface water of the Iraqi marshes. The changes of the flow and quality of the permeate and concentrate of the RO membrane system with time were investigated. In addition, salt rejection by the RO membrane including total dissolved solid (TDS), electrical conductivity (Ec), total hardness (TH), sodium (Na), potassium (K), carbonate (CO3), bicarbonate (HCO3), alkalinity (Alk.), chloride (Cl-), total organic carbon (TOC), nitrite (NO2), nitrate (NO3), phosphate (PO4), sulfate (SO4), iron (Fe)  and zinc (Zn) were also studied . Moreover, the effect of the pretreatment on the water quality that is used as feed water for the RO system was included in this study. The results showed that 95.9% to 98% of total dissolved solids (TDS) removal percentage was attained for all runs conducted for the three selected sites. In addition, a wide range of permeate water flux which was (0.3442 – 1.3042) Lpm/m2 was achieved. Moreover, pretreatment unit results showed that 90.67%, 93.9%, and 97.32% of turbidity reduction and 50.8%, 60%, and 71.7% of total organic carbon (TOC) reduction of the feed water of the three selected locations were achieved. Keywords: Brackish water, Desalination, RO membrane, Salt rejection.

  • Assessment of Building Collapse in Nigeria: The Major Causes and Practical
           Remedies

    • Authors: Kolawole; Oluwatobi M.
      Abstract: Over the past years, the magnitude of the occurrences of building collapse has led to the loss of life and properties in Nigeria. Research shows that in recent times, the collapse of building in Nigeria is becoming increasingly rampant and if stringent measures are not engaged to curb this menace, there could be cases of more devastating challenges in future. In a bid to and provide practical measures through which the menace of building collapse can be curbed, this study examines the causes of building collapse in Nigeria. The methodology includes; conduction of investigations and site inspections and secondary data. The study reveals that building collapse in Nigeria emanates majorly from; overloading, lack of maintenance, illegal Alteration or conversion of existing buildings, quackery, use of inadequate/improper foundation, inadequate preliminary site investigation, poor concrete mix ratio, inadequate structural analysis / design, lack of adherence to material specification / poor building material specification, inadequate supervision by professionals. Force majeure was also identified one of the causes of building collapse. Moreover, based on the results obtained in this study, recommendations were made to prevent the future occurrence of this menace. It is concluded in this paper that building collapse in Nigeria could be substantially reduced if the identified pitfalls are avoided.

  • Spatial Distribution of Fluoride Concentration in Drinking Water Sources
           in Northern Tanzania

    • Authors: Mengiseny E. Kaseva, Christopher Mayige, Fredrick Salukele, Godfrey Mkongo, Eliud M. Sangeti
      Abstract: Study on Fluoride concentration levels and spatial distribution was carried out in a total of 366 drinking water sources in Arusha city, Ngorongoro, Arumeru, Monduli, Karatu, Meru, and Longido districts in Arusha Region, Northern Tanzania. The main objective of the study was to map occurrence and level of Fluoride concentrations in the existing and potential sources of drinking water supply in the case study areas. Determination of Fluoride concentration was analysed by electrochemical methods using a Fluoride ion selective electrode. The obtained results indicate that out of the 22 water sources assessedin Arusha city, only 14 (63%) meets the recommended Fluoride concentration level (4 mg/L) for drinking water standards of Tanzania. In Karatu district out of the 22 water sources assessed, 9 sources (41%) do not meet the Tanzania standards of Fluoride concentration levels in drinking water sources, while in Longido all 18 boreholes had Fluoride concentration levels above the recommended Tanzania standards. Out of the 11 assessed spring water sources, 6 (55%) had concentration above the recommend levels. However, Fluoride concentrations in all rivers in Longido district were found to be within the allowable standards. In Monduli district 2 dug wells had Fluoride concentration between 0.34 and 1.0 mg/L, respectively. Fluoride concentration in Lake Manyara was found to be as high as 18 mg/L, which is far beyond the recommended concentration level in Tanzania as well as by World Health Organization (WHO). Fluoride concentrations in almost all spring water sources in Monduli district have Fluoride concentrations allowable both by Tanzania and WHO standards. In Meru district the percentage of water sources with Fluoride concentration within the allowable levels in Tanzania and can thus can be tapped for safe water supply are boreholes 64.3%, springs 66.7%, shallow wells 25.7% and rivers 71.5%. In Arusha District springs constitute the main water source. Out of these 77% have Fluoride concentration within Tanzania allowable standards. As for Ngorongoro out of 51 water sources assessed only 4 have Fluoride concentration above 4.0 mg/L, suggesting a major leeway and flexibility in terms of selection of water supply sources in this district. Results of this study indicate a challenging situation in terms of selection of source of safe water supply in Arusha city and Meru district as many of their water sources have Fluoride concentration above the permissible levels in Tanzania. However, the situation is different in Karatu, Longido and Monduli, Arumeru and Ngorongoro districts where substantial water sources have Fluoride concentration within levels acceptable for drinking water supply in Tanzania. Keywords: Fluoride Concentrations, Allowable Concentration levels, Drinking Water Sources

    • Authors: Araloyin Funmilayo Moyinola, Alao Olufemi Folasade
      Abstract: The study investigated the housing satisfaction among elderly in Osogbo, Osun state, Nigeria.  It examined the socioeconomic characteristics of the elderly in Osogbo, their housing characteristics and their level of housing satisfaction with a view to providing an enabling environment for the elderly. The study employed both primary and secondary data. The study population is the elderly residents in Osogbo, Osun state. The study adopts members of the Elderly Person Association of Nigeria (EPAN) resident in Osogbo, Osun state as its sample frame. EPAN has 333 (three hundred and thirty three members). The information required from respondents includes their socioeconomic characteristics, the housing features of their present residence, level of satisfaction with their residences and environment.The results revealed that respondents are within the age of 60 years and 90years. Majority of the elderly depend on pension, while others rely on business profit and support from family and friends. The study found that elderly residing in their own house have a higher level of housing satisfaction compared to elderly tenants. The study also found that the housing satisfaction of elderly can be improved through the socio-economic empowerment and modification of their housing characteristics to suit their need.

  • Physico-Chemical and Microbiological Assessment of Surface Water Quality
           of a Himalayan Wetland Deoria Tal, India

    • Authors: Sheetal Chaudhary, Ramesh C. Sharma, Rahul Kumar
      Abstract: The Water Quality Index (WQI) is considered as an important method to assess the water quality of a water body for its users. This study was carried out to assess the water quality of a Himalayan wetland Deoria Tal. Deoria Tal is one of the most important wetlands of the Garhwal Himalaya, India. It is the major destination for tourists, trekkers and local inhabitants. The water samples were collected for a period of one year during April, 2014 to March, 2015. In order to develop the water quality index samples were subjected to a comprehensive physico-chemical analysis of 20 parameters which include air temperature, water temperature, pH, conductivity, turbidity, dissolved oxygen, free CO2, biochemical oxygen demand, total dissolved solids, transparency, total alkalinity, hardness, chlorides, sulphates, phosphates, nitrates, Calcium, Magnesium, Potassium and Sodium. The WQI was calculated and the value was obtained as 76.15. Most of the values of physico-chemical parameters are within the prescribed limits of WHO/BIS for drinking water. Water Quality Index (WQI) calculated based on the weight values of these parameters also revealed the ‘good’ quality of lake water. The α-diversity of microbes was found to be 18 in the water of Deoria Tal. The water of the lake is fit for human consumption. Keeping in view the importance of the lake and to provide the sustainable water quality for users its conservation and management is priority in the Himalayan region.

  • Visibility Trends in Baghdad City During the Period 2005-2014

    • Authors: Ahmed Hassoon Ali, Basim Ibraheem Wahab Al-temimi, Younis Swadi Taliaa, Ali Dhamin Khishala
      Abstract: Trends in horizontal visibility for Baghdad city, haziness for the period between 2005 and 2014 were assessed in view of information for daily horizontal visibility. The average (means) of annual visibility were determined for Baghdad as a whole, the results show that the average annual visibility ranged between 8592 m and 6429 m at years 2006 and 2009 respectively. However, the monthly visibility flocculate between 10385 m in November 2006 and 4216 m in May 2012. Analysis in term of linear regression was utilized for describing long-term annual trends in these variables. For the last ten years, there was a significant decreasing in horizontal visibility (-2.1 km/decade from 2005 to 2014). According to rapid increase in energy consumption, the consistent temporal and spatial variations of visibility and haze support the speculation that increased aerosol loadings were responsible for the observed decreases in horizontal visibility over Baghdad city.

  • The Origin of Conflict to Dispute in Nigeria Construction site

    • Authors: Alejo; Ayodele Oluwole
      Abstract: Conflict in the construction industry is so complex that if not properly handled, can escalate to litigation or reduce productivity, this result to varieties of people involved in construction production. Conflict is inevitable in Nigeria construction site due to diverse religion, ethnicity, tribes and other man made factors. Hence, conflict often leads to dispute. Disputes have become an endemic feature of the Nigeria construction industry; if they are not resolved promptly they can result in drawing back construction projects with considerable cost. The survey method adopted for this work through questionnaire; the questionnaires were distributed to contractors, clients and consultants in the construction site in Lagos state, Nigeria. The data collected were analyzed in rating form to determine the major causes of conflict to dispute in Nigeria construction site. The results obtained from ranking analysis shows that specification and design oversight, poor materials usage, bankruptcy of contractor, cost overrun, delay and time overrun and poor workmanship were rank high on the causes of disputes in Nigeria construction site. The research concluded that dispute causes more harm than good in construction project, therefore action should be taken to minimize such dispute in construction site in order to improve the effectiveness and efficiency of construction industry. Keywords:  Conflict, Conflict management, Dispute, Delay, Construction site.

      Abstract: Maintenance is the preservation of buildings in their initial functional, structural, aesthetic state, so that they continue to remain in such healthy state and retain their value and standard for a long period of existence. The aim of research is to know the maintenance techniques employed in the tertiary institutions, examine the physical state of building within the study area and evaluate the challenges facing maintenance of the tertiary institution buildings with proffer solutions.  Data for this study were collected through personal observation, desk research, oral interview and convenient sampling techniques was used to distribute the questionnaire and it was concluded from the findings that: corrective maintenance is the most applicable technique employed in the study area: roof leakages was the major defects in buildings and major challenge facing maintenance of tertiary institution buildings is finance.  Finding also revealed that most of the tertiary institutions in ondo state have works and maintenance unit with sustainable maintenance policy, their staff needs adequate training and necessary update on how to execute maintenance work. Furthermore, inadequate expenditure in maintenance, shortage of staff, lack of maintenance specialist and poor resources management are the deficiencies that inhibits maintenance discharge in the study area. It was recommended that there should be adoption of corrective maintenance buildings in the study area should be regularly maintained to guide against roof leakage, cracks on the wall and maintenance work should be adequately finance.

  • Assessment of Poor Drainage System in Building within Low Land Areas.

    • Authors: Alejo; Ayodele Oluwole
      Abstract: Consequent upon poor drainage system urban environment in Nigeria are facing a lot of problems. The study is hinged on investigating the causes of drainage system and immediate causes of poor drainage system. Infrastructural and environmental problems caused by the drainage systems and measures of maintaining the associated problems in the area under study. Akure the capital of Ondo state in Nigeria is a fast growing city in terms of infrastructural development which involves concretizing and construction of the city land surfaces thus, leading to flooding. The finding reveals that the drainage system in some low land areas in Akure were not well designed due to low level of technical know-how, the disposal of debris into drainage have added adversely to the problem of flood in the study area; in Akure metropolis, flooding being observed to be the principal consequence of poor drainage systems. Also, the tested study revealed that poor drainage systems were actually the main cause of incessant flooding, destruction of environment infrastructural facilities, loss of lives and properties in the study area: Akure metropolis.

  • An Investigation into the Potential of Architects’ Contribution to
           Furniture Design in Uganda

    • Authors: Judith Alowo, Kenneth Ssemwogerere
      Abstract: The purpose of the study was to investigate how architects in Uganda can contribute to the enhancement of the quality of furniture produced in Uganda. The objectives of the study were to investigate the relevance of architects in the field of furniture design and to find out the extent of architects’ involvement in furniture design and production in Uganda. Data was obtained from literature, interviews with architects, furniture manufacturers and carpenters. The study revealed that furniture makers in Uganda obtain designs from catalogues of furniture manufacturers in Asia like China. It was found that some manufacturers have designers some of whom are carpenters. The researchers investigated architects’ perception of furniture design in relation to their other architectural responsibilities and found that architects agreed that furniture is part and parcel of architecture. Architects also expressed willingness to design furniture for projects because they understand that furniture is intrinsic to architecture. The level of involvement of architects in furniture design is however limited by challenges which are contractual and economical among others. The research concluded that there are design gaps in the furniture industry because the responsibility of designing furniture is relinquished to people who have no knowledge of design principles, resulting in repetition of the same design by different producers and consequent lack of variety on the furniture market. The research also concluded that architects have the potential to make revolutionary contributions to the industry through collaborating with furniture producers. Keywords: Quality, Furniture, Design, Production, Architects, Uganda.

  • The Impact of Storage on the Quality of Sachet Water Produced in Amassoma,
           Nigeria

    • Authors: Odafivwotu Ohwo
      Abstract: Inadequate storage may affect the quality of sachet water; hence, this study was designed to determine the impact of storage on sachet water quality produced in Amassoma. To achieve this aim, 100 sachet water samples were randomly collected on the day of production and 10 sachets were sent to the laboratory within 24 hours for analysis to serve as control. The remaining 90 samples, 45 each were stored at room and atmospheric temperatures respectively. At the intervals of week-4, week-8 and week-12, ten sub-samples each was randomly drawn from the respective 45 samples stored at both room and atmospheric temperatures and were sent to the laboratory for analysis. The T-test and ANOVA analyses show that the observed variations in some of the quality parameters were not significant. Also, all the physico-chemical parameters except pH were within the WHO thresholds for potable water. However, all the samples show traces of total coliform and faecal coliform counts in the storage periods, while the control samples tested positive for Escherichia coli. It is therefore recommended that the National Agency for Food, Drug Administration and Control should step-up it’s monitoring of sachet water companies to ensure that standard production procedures are maintained.
