Projected climate risks for rice crops in Casamance, Southern Senegal

The climate risk concept is crucial for agricultural production in vulnerable regions. In this work the climate conditions that influence the climate risk for rice crop in Casamance are presented. The future occurrence of drought and extreme precipitation conditions in the most critical phases of the rice plant evolution has been evaluated. Regional climate models (RCMs) outputs projections from CORDEX under two...

Soil nematodes status of crude oil polluted sites in Bodo community, Gokana Local Government Area, Rivers State, Nigeria

Crude oil spill destroys biodiversity and adversely impacts the physicochemical characteristics of the terrestrial and aquatic environments. The population characteristics of soil nematodes can serve as indicators of alterations in the terrestrial environment. To determine the effects of crude oil spillage on the soil nematode fauna status; a study was carried out at an impacted area in Gokana Local Government Area of...

Cost minimization and operation optimization model for strategic waste management decision plans: A case study

The design of a sustainable waste management system is pivoted on the ability to generate and compute real-time operational data for a strategic developmental decision plan. The real-time waste data generated at the University of Lagos Campus waste management system was used to develop a mathematical model with three operational indicators, namely, Total Cost Indicator (TCI), to show the overall daily cost for managing...

Kinetics of phosphate adsorption by Ca/Cr layered double hydroxide

Kinetics of phosphate adsorption by Ca/Cr layered double hydroxide (LDH) in a batch reactor was investigated in this study. The kinetic experiments indicated that the sorption of phosphate from the synthetic feed solution by the synthesised LDH was very fast, with over 98% removal being achieved within 5 min of contact. Kinetic modeling of the sorption process to different kinetic models (pseudo first order, pseudo...

Variability of physiochemical properties of livestock manure with added wood shavings during Windrow Composting

Composting livestock manure still remains one of the best waste-to-resource technologies practiced in the world. There is however, limited information on composting of livestock manure and wood shavings in Cameroon.  This research, carried out in South West Region of Cameroon assesses the variability of physiochemical properties: pH, pile temperature, mass, volatile solids contents (VS), total solids (TS) and total...
