Irrigation And Drainage Channels

The Vega Baja region lays on the lower course of the Segura River (southeastern Spain). It is one of the six traditional “huerta” European landscapes and has an ancient, extensive, and complex network of irrigation and drainage channels. The accumulation of floating waste causes numerous economic, environmental, and landscape problems in its irrigation infrastructures, hindering farmers’ water management practices. This work classifies and estimates the total volume of floating waste at various points along the Segura River and its irrigation channels as a first systematic approach to define and quantify the problem of floating waste accumulation. Aerial images taken by a drone were analyzed over time and a manual count of residues was performed on selected points. The results obtained show that reeds and residues of riparian vegetation represent more than 95% of the floating debris volume measured on the riverbed. Anthropogenic waste, which represents less than 5% of debris volume, was characterized, finding that plastics of domestic sources are the most abundant by count (14.9%) and only a reduced part of the floating waste can be attributed to agricultural activities (3.8%). Assessing the type and origin of the floating waste is essential to inform the actions required in order to avoid the floating waste reaching the Mediterranean Sea.

Abstract. The impacts of coniferous plantation forestry on the biology of upland streams in the UK are firmly established. Whilst benthic communities have been well studied, very little research has considered the impacts of riparian forestry management on adult stream insects, yet the essentially terrestrial adult (reproductive) phase may be important in determining the abundance and distribution of larval stages. Riparian vegetation has a potentially strong impact on survival and success of adult stages through alteration of microclimate, habitat structure and potential food sources, in addition to effects carried over from larval stages. Here, current riparian management strategies are analysed in the light of available information on the ecology of adult stream insects. On the whole, management practices appear to favour adult stream insects, although an increase in tree cover in riparian areas could be beneficial, by providing more favourable microclimatic conditions for adults. This conclusion is drawn based on rather limited information, and the need for further research into the effects of riparian forestry management on adult stream insects is highlighted.

Conveyance Losses

Irrigation canals are generally made through porous soil formations, since the soil is loose porous media – a huge amount of canal water is lost to conveyance losses. The situation becomes direr when these losses result in non-beneficial losses. The Sindh province of Pakistan has more than 70% saline groundwater, conveyance losses to such areas in the province not only become unusable but also creates water management problems. Perhaps the only cost-effective way to address these losses is canal lining. The present study was conducted in the command area of Belharo distributary, Sindh, Pakistan with an aim to determine the extent of losses from the tertiary irrigated network as these water channels are less considered in the literature with regards of conveyance losses. Using water balance method, conveyance efficiency and conveyance losses at 30% lined and 50 and 75% unlined length of the watercourses was observed. The results revealed that the tertiary irrigation channels face an average of 43% conveyance losses and major proportion of these losses is lost to non-beneficial losses from the study area. The study further suggests 75% lining of watercourses in order to minimize non-beneficial losses. This study also infers that with the use of geo-membrane lining, sizeable amount of fresh water can be saved. Doi: 10.28991/cej-2021-03091756 Full Text: PDF

Talent management is a mechanism which involves hiring, assigning, transferring, growth and retaining of employees in the organisation. It is important because it ensures top talent is attracted and effective employee performance, employee’s engagement and retainment of top talent. A thorough review of the work carried out shows that businesses are experiencing a talent shortage in this competitive period, which has placed pressure on them to recruit the best talent and to ensure that workers enter the company and choose to remain in the organization rather than seeking opportunities elsewhere. The importance of the different components of talent management for employees was another unexplored area. Existing research has not been able to resolve the problem of defining the importance of the different talent management elements and the weighting they bear for employees. The problem of employee perception and management perception of the efficacy of talent management activities has also not been discussed, to address this gap the researcher has attempted to study talent management practices in service sector. The author followed a systematic approach to address the research questions, the literature was reviewed, in research methodology, primary data was collected through questionnaire which followed a sampling method accompanied by hypothesis testing which revealed that the effective practices boosts up the efficiency of the employees and performance of the organization too.

In the region of Alentejo, Southern Portugal, as a consequence of the implementation of the Alqueva global irrigation system, agriculture intensification is challenging the sustainability of the farming systems. The demand for water and for fertilizers is increasing but so is the demand for water use efficiency (WUE) and for nutrient use efficiency (NUE). Increasing resource-use efficiency while reducing yield gaps can be addressed by suitable agricultural management practices, as in the case of crop rotations. Based on a demonstration project carried out in two farms located in Baixo Alentejo, within the Alqueva irrigation network, soil fertility parameters, WUE and NUE (for nitrogen, phosphorus and potassium) were studied in three maize-based cropping systems: a maize monoculture (M-M) and two rotations, barley+maize-barley (BM-B) and sunflower-barley+maize (S-BM). The total soil organic matter content increased in the two rotations, an important observation especially in soils with low organic content. The final balance of extractable phosphorus and potassium was positive in the BM-B rotation. Water use efficiency values point to a less balanced performance of the S-BM rotation. The WUE and the nitrogen NUE in the different crops and rotations followed a similar pattern. The M-M and BM-B crop successions showed the best indicators of NUE for nitrogen and phosphorus. In all the cropping systems, the potassium NUE was low, suggesting the need to carefully equate the additions of this nutrient by fertilization.

Peak Runoff

Rapid development in a watershed affects surface and ground water sources. Urbanization results in increased environmental pollution and groundwater pollution. Best water resource management practices are Low Impact Development (LID) such as bioretention, vegetative swales, permeable pavements, and rainwater wetlands have been implemented to reduce the adverse effects of urbanization such as flooding by reducing peak runoff on the surface and thereby managing rainwater runoff. The purpose of this study was to analyze microbial contamination in wastewater originating from city drainage channels. The research was carried out experimentally by taking water in Item River, Kemayoran directly and put it in an electric bioretention tank. The rain-wastewater-bioretention (RWB) tank is in the form of a watertight tank measuring 60 cm in diameter by 80 cm in height with a medium of 50 cm, leaving 30 cm to provide space and time for standing water during infiltration time. The results of the water taken on the 2nd day through Bioretention carried out laboratory testing with the scope of Microbiological analysis of Environmental Health Quality Standards, Escherichia coli levels decreased from 17 APM/100 ml to 9 APM/100 ml. In addition, total Coliform levels from 2800 APM/100 ml to 270 APM/100 ml.

Grower Survey

In 1989, 52 cotton growers from the 7 major cotton areas of New South Wales were surveyed regarding their weed-control costs, major weed problems and herbicide use. This paper presents and discusses the major results from this survey. On average, weed control costs the cotton grower $A187/ha annually, the major components being $76/ha for cotton herbicides and $67/ha for hand chipping. The major cotton weeds are Xanthium occidentale, X. spinosum, Cyperus spp., Physalis spp. and Ipomoea lonchophylla. Although these weeds affect a large proportion of the cotton-growing area, their incidence is generally stable or declining under the current management systems. However, Cyperus spp., which presently affect 15% of the cotton area, are escaping the weed management practices and rapidly becoming the major weed problem in many fields. Diplachne fusca is a major weed on irrigation channels and is not controlled by the registered herbicides. Trifluralin, diuron and fluometuron herbicides are used in cotton by over 60% of cotton growers. Glyphosate is used by 59% of growers in fallows prior to cotton, and atrazine, diuron and glyphosate are used on irrigation channels by over 60% of growers. Generally, cotton growers are dissatisfied with t h e high cost of weed control and the ineffectiveness of control of some problem weeds such as Cyperus spp.
