Characterization of the development and productivity of Jatropha curcas L. plants according to provenance and tillage in Bargny, Senegal

Among the crops that can potentially be used to provide the raw material needed for liquid biofuel production Jatropha curcas L. is the one that generates most interest in many development projects. The aim of this study is to evaluate the production and development of 3-year-old J. curcas L. seedlings in 2012. The results showed that after three years of planting, subsoiling and provenance have no effect on growth...

Spatial patterns of climatic variability and water budget over Sudan Savannah Region of Nigeria

The study examined the effect of climatic variability on climatic water balance over Sudan Savannah, Nigeria. Temperature and Rainfall data were collected for the period 1943-2012 from the Nigerian Meteorological Agency. The data were divided into two climatic years 1943-1977 and 1978-2012. On the whole, rainfall amount decreased from a very high mean value of 981.5 mm in Yelwa (Lat. 10.88 N; Long. 4.75 E) to a very low...

Future evolution of surface temperature extremes and the potential impacts on the human health in Senegal

Climate change impacts negatively vulnerable regions such as West African countries like Senegal, through an increase of climate extremes. The objectives of this study is to analyze the future evolution of the extreme temperature events and their impacts on human health in Senegal during the cold (DJF), hot (MAM) and wet seasons (JAS) under the greenhouse gas scenarios RCP4.5 and RCP8.5 using Climate projections of five...

Assessment of hydrological pathway and water quality of the songor wetland, Ghana

Wetlands regulate sediment accumulation, minimize pollution load and act as a buffer against coastal erosion. However, the overflow of seawaters into closed lagoons and wetlands could cause an excessive build-up of solutes through evaporation and could threaten the health of the aquatic life. This study examined hydrological regime, water quality and spatial distribution of flora within the Songor Wetland, Ghana using...

Active and passive air quality bio-monitoring in the tropics: Intra-urban and seasonal variation in atmospheric particles estimated by leaf saturated isothermal remanent magnetisation of Ficus benjamina L (Moraceae)

Atmospheric pollutant emissions are likely to increase continously in developing cities like Abidjan (Ivory Coast) where air quality strategies are ineffective or not yet implemented. This could result in a big risk to human health. Local meteorological parameters can have both positive or negative effect on habitat quality depending on the biomonitoring approach used. This study investigates the sources and factors...
