The Vulnerability of the selected boreholes to bacteriological indicators in Parts of Owerri West of Southeastern Nigeria was determined using Vulnerability Index (VI). Distances between the selected boreholes and anthropogenic activities were measured. Sampled Borehole (SBH) 3, 5, 8 did not meet the 30 m WHO STD, while defecation, bathing and washing of clothes were found within the circumference of SBH 6, 9 and 10 respectively. Total bacteria, total coliform and faecal counts were evaluated using the standard plate count method and the Most Probable Number (MPN) technique, respectively. The mean total bacteria count of the selected bore water samples ranged from 0.08-2.73 × 10 2 CFU that constituted between 0.59-20.31%, with the mean value of 1.34 × 10 2 CFU/ml, Total coliform count ranged from 6-19 MPN/100 ml constituting 4.72-14.96%, with the mean value of 12.7 MPN/100 ml and Faecal coliform count ranged from 9-21 CFU/ml constituting 7.09-14.69% with the mean value of 14.3 (CFU/100 ml) all above the WHO STD respectively [1]. The isolated and identified bacteria include: Enterobacter sp., Alcaligenes sp., Escherichia coli, Proteus sp., Klebsiella sp., Pseudomonas aeruginosa, Acinetobacter sp., Staphylococcus aureus and Bacillus sp. accordingly. From the result of Vulnerability Index (VI) calculated and rated, the selected boreholes are highly affected by faecal count rated 0.21 within the rating of 0 signifying highly vulnerable. Furthermore, results of total bacteria a, total coliform and overall result of bacteriology using VI rating recorded 1.98, 1.02, 1.07 respectively, indicating highly resilient in rating. The vulnerability of the selected boreholes to bacteria means that, water resources in this area is not suitable for human consumption, hence water borne diseases.

“…This time is usually much longer than the length of term of decision makers and administrative officers (Marlow et al 2013;Brown and Farrelly 2009). However, decreasing vulnerability and increasing the capacity of riverside may bring not only less adverse consequences on local level but also social, economic and environmental benefits for the region, (Sivapalan et al 2012;Bresch 2017).…”

A decrease of flood damages in the future requires not only adaptation to flood caused by present day climate, but also climate change effects on floods should be taken into account. The paper illustrates the need to take into account changing climate conditions in flood adaptation strategies and to apply in practice the concept of integrated water resource management (IWRM). IWRM is based on a number of policy instruments, economic instruments, political signals, and also, on the effects of climate change on floods and collaboration across national, regional and local administrative units. The guidelines for a country adaptation to floods in a changing climate are outlined. A comparison of the adaptive capacities in Poland and Norway is used to illustrate the need for the implementation of proposed guidelines to assure flood risk management under climate change in a sustainable way.

“…However, demographic changes including the ageing population, socio-economic factors, climate change, biodiversity, energy use, water supply and consumption, as well as ageing water and wastewater infrastructures has put increasing pressure on these urban water systems [1,15]. Marlow et al [16] has also raised similar concerns on centralized urban water systems, which are maladapted to these challenges. In addition, the typical centralized system can limit the potential to adapt water supply systems to local opportunities and needs [1].…”

This paper presents a critical review of the physical impacts of decentralized water supply systems on existing centralized water infrastructures. This paper highlights the combination of centralized and decentralized systems, which is referred to as hybrid water supply systems. The system is hypothesized to generate more sustainable and resilient urban water systems. The basic concept is to use decentralized water supply options such as rainwater tanks, storm water harvesting and localized wastewater treatment and reuse in combination with centralized systems. Currently the impact of hybrid water supply technologies on the operational performance of the downstream infrastructure and existing treatment processes is yet to be known. The paper identifies a number of significant research gaps related to interactions between centralized and decentralized OPEN ACCESSWater 2015, 7 154 urban water services. It indicates that an improved understanding of the interaction between these systems is expected to provide a better integration of hybrid systems by improved sewerage and drainage design, as well as facilitate operation and maintenance planning. The paper also highlights the need for a framework to better understand the interaction between different components of hybrid water supply systems.
