Farmers’ perception of the effects of soil and water conservation structures on crop production: The case of Bokole watershed, Southern Ethiopia
Level soil bunds (LSB) and stone bunds (SB) have been widely implemented in Bokole watershed with World Food Programme (WFP) support since 2000-2001. However, the performance of structures against the target has not been studied. This study assessed farmers’ opinion on the effect of soil and water conservation (SWC) structures, particularly level soil bunds and stone bunds, in improving agricultural crop...

Solid waste dumping site suitability analysis using geographic information system (GIS) and remote sensing for Bahir Dar Town, North Western Ethiopia
Solid waste dumping is a serious problem in the urban areas because most solid wastes are not dumped in the suitable areas. Bahir Dar Town has the problem of solid waste dumping site identification. The main objective of this study was to select potential areas for suitable solid waste dumping sites for Bahir Dar Town, which are environmentally suitable. The main data used for this study were spot image with a spatial...

Elimination of Cu (II) and Zn (II) ions in mono-element and the bi-element aqueous solutions by adsorption on natural clay of Bikougou (Gabon)
This work was undertaken to evaluate the potential of the clay of Bikougou to remove copper (II) and zinc (II) ions (Cu2+ and Zn2+) in mono-element and binary aqueous solutions. The experiments were carried out by employing the batch technique through the variations of pH, clay mass, ionic strength, concentration in metal, temperature and contact time. The quantity of ions coppers (II) or zinc (II) adsorbed increases...

Groundwater exploitation in the Abakaliki metropolis (southeastern Nigeria): Issues and challenges
This paper assesses and evaluates geologically related problems and issues associated with five ‘abortive’ boreholes drilled within the Abakaliki metropolis, southeastern Nigeria. Results of the vertical electrical geophysical soundings (VES), carried out in these borehole locations, show that the underlying Abakaliki Shale Formation in those areas has six layered model. While the uppermost layer has an...

Seasonal fluctuations of phlebotomines sand fly populations (Diptera: Psychodidae) in the Moulay Yacoub province, centre Morocco: Effect of ecological factors
An entomological survey of phlebotomine sand flies was conducted in the Moulay Yacoub province, central Morocco. An anthropic niche (Ouled Aid) and a wild niche (Zliligh) were selected. Sand flies were collected twice a month between April 2011 and March 2012, using sticky traps and CDC light traps. 3675 specimens were collected (78.3% males/21.7% females) which composed of eight species divided into two genera:...
