Assessing the farmers perception of climate variability and change: A case study of Miesso-Assebot Plain, Eastern Ethiopia
Assessment of farmers’ perception and adaptation mechanisms at local level has enormous advantages in Ethiopia, where the driver of the economy is agriculture. This study was conducted to assess the perceptions of farmers to climate change and increased climate variability, and to identify the potential adaptation options. Most farmers noted an increase in temperature and decrease in precipitation in the last...

Wood-cement composites using suitable mix of sawdust and fibres from veins of palm tree leaves
Some tropical wood species are currently used in wood work and generating an important quantity of wood waste in Benin, Western Africa. Recycling these wastes through building material is a way to solve environmental challenges, but the wood resources are not inexhaustible and vegetable fibers such as Eleais guineensis fibers, obtained from veins of palm tree leaves are available in nature. The main concern of this...

Studies on the effect of simulated acid rain of different pH on the growth response of TMS 419 cultivar of Manihot esculenta (Crantz)
The growth response of TMS 419 cultivar of cassava Manihot esculenta Crantz exposed to simulated acid rain of different pH was studied. The plant was exposed to simulated acid rain of pH 2.0, 3.0, 4.0, 5.0, 6.0 and 7.0 (control), respectively. Simulated acid rain induced morphological changes including chlorosis, senescence, necrosis, leaf abscission, leaf folding and death. Plant height, leaf area, fresh weight, dry...

Valorization of waste plastic bags in manufacturing of binders for bituminous concretes for road coatings
In 2012, Beninese landfills have quantified more than 12,000 tons plastic wastes with more than 50% of bags. The non-biodegradable nature of plastic generated an unprecedented environmental nuisance. The search for suitable solution led opting for partial recycling through construction processes. This article is devoted to characterization of new bituminous binders built of 50/70 graded bitumen to which is incorporated...

Empirical modeling of solar radiation for selected cities in Nigeria using multivariate regression technique
In this paper, the data for solar radiation, minimum and maximum temperatures, wind speed and evaporation for the years 1970-1995 and for fourteen stations taken over Nigeria were obtained from the archives of the Nigerian Meteorological Agency (NIMET), Oshodi, Lagos. The distributions of solar radiation with each of the four meteorological variables were observed. It was found that solar radiation was adequately...

Variation of small scale wetland fishery in relation to land use within Mpologoma riverine marsh in Eastern Uganda
In densely populated areas such as those in Eastern Uganda where livelihoods demands create immense pressure on environmental resources, small scale wetland fisheries may be disturbed by agriculture practices. The study carried out between 2011 and 2012, investigated the variation of fish catch at the different wetland sites in relation to land use in Mpologoma riverine marsh. Four sites were identified to represent...

Evaluation of groundwater suitability for drinking, domestic and irrigational purposes: A case study of Makurdi metropolis and environs, Benue State, North Central Nigeria
A study of groundwater samples from Makurdi metropolis and environs was carried out to assess its suitability for drinking, domestic and irrigational purposes. The chemistry of groundwater within the study area with respect to pH, total dissolved solids (TDS), NH3-, NO3-, Cl-, Na+, K+, Ca2+, Mg2+, HCO3-, SO4-, Fe3+, Cu2+, Mn2+ and Zn2+ was used to determine its suitability for drinking. Some parts of the study area have...
