The effect of physico-chemical parameters on speciation of trace metals insediments from inland and coastal waters of Ghana
The speciation of cadmium, lead, copper, zinc, manganese and iron into exchangeable, carbonate, reducible and organic bound fractions was studied in sediments from coastal and freshwater environments in Ghana. This was relevant as the species in which metals are stored within specific sediment components is important in determining their impact on the environment -

Thermal efficiency of charcoal fired cookstoves in Ghana
Biomass is a predominant feed-stock for household cooking and heating in developing countries. Charcoal fired cookstoves can be considered an important intermediary for sustainable energy consumption as well as promoting healthy kitchen environments due to the significant reduction in the emission of indoor pollutants associated with smoke in wood fires. -
Geochemical Assessment of the Impact of Mine Tailings Reclamation on the Quality of Soils at AngloGold Concession, Obuasi, Ghana
This study assessed the geochemical impact of mine tailings reclamation on the quality of soils from the AngloGold Concession, Obuasi, Ghana. Soil samples from mine tailings reclamation sites were evaluated for the concentrations of plant nutrients and trace metals. Contaminations of trace metals, using geochemical pollution indices were used to assess possible effects on agriculture and livelihoods. The average pH ranges from 7.6 to 8.4 at the ex-tailing sites while the control site is 6.0. Organic carbon and nitrogen levels at the extailings site are low due to topsoil loss. -
Performance evaluation of prototype mechanical cassava harvester in three agro-ecological zones in Ghana
Large-scale cassava harvesting, especially during the dry season, is a major constraint to its industrial demand and commercial production. -
Performance evaluation of prototype mechanical cassava harvester in three agro-ecological zones in Ghana
Large-scale cassava harvesting, especially during the dry season, is a major constraint to its industrial demand and commercial production. Manual harvesting is slow and associated with drudgery and high root damage in the dry season. Research on mechanisation of cassava production is very low especially in the area of harvesting, and currently there exists no known functional mechanical cassava harvesters in Ghana. -
Knapsack Shield for Herbicide Weed Control in Field Crops
Over dependence on inefficient tools such as hoes for critical field operations limits crop production in developing countries. -

Influence of Seed Storage Techniques on Germinability and Storability of Cowpea (Vigna unguiculata (L) Walp)
This study was set to investigate the germinability and storability of the newly released cowpea genotypes and secondly the influence of different storage materials under ambient storage condition on seed vigour and germination over time. -
Geographic differences in patterns of genetic differentiation among bitter and sweet manioc (Manihot esculenta subsp. esculenta; Euphorbiaceae)
• Premise of the study: Manioc (Manihot esculenta subsp. esculenta), one of the most important tropical food crops, is commonly divided according to cyanide content into two use‐categories, “sweet” and “bitter.” While bitter and sweet varieties are genetically differentiated at the local scale, whether this differentiation is consistent across continents is yet unknown
