Spatio‐temporal characteristics of meteorological drought under changing climate in semi‐arid region of northern Ethiopia

Abstract: Background: Below-normal availability of water for a considerable period of time induces occurrence of drought. This paper investigates the Spatio-temporal characteristics of meteorological drought under changing climate. The climate change was analyzed using delta based statistical downscaling approach of RCP 4.5 and RCP 8.5 in R software packages. The meteorological drought was assessed using the Reconnaissance Drought Index (RDI).Results: The result of climate change projections...

Geology And Occurrence of Groundwater In Ishieke Area, Southeastern Nigeria

ABSTRACT  The study area is located in the Abakaliki formation of Asu-River group Lower Benue Trough. The area lies between latitude N060221 011to N060 281 011of the equator and longitude E0080 001 011 to E 0080 061 011of the Greenwich meridian. The study was carried out to ascertain the geology and the occurrence of groundwater in the area through detail geological field mappings geophysical investigation and pumping test. Field observations shows that the area is made up of two lithologic...

Groundwater Chemistry and Modeling of Aquifer Depth around Uburu-Okposi Salt Lakes, South Eastern Nigeria

Abstract  The study area comprised Uburu and Okposi towns in Ohazara Local Government Area, Ebonyi state and it lies between latitudes 60 00’N and 60 05’N, and longitudes 70 44’E and 70 50’E. The area belongs to the saline hydrogeological groundwater basin of Albian Asu River Group in Cross River Basin. Three major outcrops of saline groundwater in the study area are: Umuchime- Uburu lake, Ivu-Ezizo and Amaechi-Okposi lakes. The saline lakes support long production of salts by rural ...

Culture of Zooplankton (Brachionus Calyciflorus, Moina Micrura and Daphnia Pulex) As Live Food for Heterobranchus Bidorsalis Hatchlings.

ABSTRACT Live food Zooplankton population density in different zones of Awuma River at Shabu were investigated and Brachionus calyciflorus, Moina micrura and Daphnia pulex screened from littoral zone of the River at Shabu before the onset of rainy season was isolated into mono specific culture in the laboratory. Cow dung, chicken droppings, groundnut cake, soyabean cake, rice bran and single super phosphate were combined in different proportions of three, four and five combinations of manure...

Socio-Economic Constraints To Community Participation In Rural Water Management In Ndarugu-Thiririka Sub-Catchment, Athi Basin, Kenya

ABSTRACT In rural areas, water availability in the right quantity and quality is an important step towards achieving socio-economic development. Thus, the provision of sustainable water supply has been a central issue in Kenya with priority on low-income rural communities and underdeveloped areas with poor water resources. This has forced many rural communities to embrace community management model in rural water systems. However, despite continued large-scale investment by the government an...

Effects Of Land Use On Spring And Streamflow Water Quality In River Malaget Sub-Catchment, Kericho County, Kenya

ABSTRACT Various studies have shown that land use impacts on water quality are attributable to about 80 % of diseases in the developing world. The main objective of the study was to evaluate the effects of land use on water quality in River Malaget sub-catchment. The specific objectives were to: i) establish spring and streamflow water quality; ii) determine the water quality index of the selected sampling points and iii) evaluate the relationship between spring and streamflow water quality ...

Analysis Of Household Water Demand, Distribution And Community Management Strategies In Nyangores Subcatchment, Bomet County, Kenya

ABSTRACT Access to quality water remains a key indicator of an improved social and economic life of any community. Due to an increasing human population, changes in land use activities and climate variability, Nyangores Basin in Kenya has been under pressure and for this reason, availability and access to quality and sufficient quantity of water has been adversely affected. Despite government plans to ensure all households access piped water; this has not been achieved as coverage is still v...

Assessment Of Water Availability And Accessibility For Healthy And Sustainable Livelihoods In Sankuri And Central Divisions, Garissa County, Kenya

ABSTRACT Availability and accessibility of safe water is key to sustainable livelihoods in the world hence, poverty eradication and good health leading to agricultural and economic prosperity. Poor water availability and accessibility is a pressing problem in developing countries in Africa, therefore, understanding of water as a natural resource and human consumption commodity can help solve the problem and contribute to achievement of Millennium Development Goals (MDGs). Kenya is a water sc...

Hydrochemical Assessment Of Surface Water In Part Of Southeastern Nigeria

ABSTRACT The area of study occurs mainly within the Calabar Flank and part of the adjacent basement terrain of the Oban Massif. The latter is composed of mainly migmatitic gneisses, phyllites, amphibolites, granites, schists and granodiorites, while the major lithologies of the Calabar Flank include carbonates, shales, claystones and sandstones. This study aims at determining the quality and usability of the water, in addition to ascertaining the possible pollutants and ways to ameliorate the...

Hydrogeological Characteristics Of Aquifers In The Greater Accra Region

The economic importance of groundwater in the Greater Accra Region cannot be overemphasized, since supply from boreholes and wells continues to be the most dependable alternative sources of water for most rural and urban communities in the region. Three different consolidated hard rocks underlie the region making it difficult to produce volumes of groundwater for supplies. Demand for portable water has led to the drilling of large numbers of boreholes. This study statistically assesses t...
