However, information is lacking in Wolaita, Southern Ethiopia. Thus, this study aimed at investigating the physiographic characteristics of agricultural lands, ...

Environmental taxation based integrated modeling towards sustainable environmental conservation approach

Background Globalization and rapid industrialization was inevitable during late nineteenth century considering the demand–supply deficit and requirements of evolving societies. However, at later stage these factors were mapped to be major reasons for the environmental pollution. Further, at the cost of environment degradation, development and economic growth cannot be achieved. The ...

The effect of phosphorus and nitrogen fertilizers on grain yield, nutrient uptake and use efficiency of two maize (Zea mays L.) varieties under rain fed condition on Haplic Lixisol in the forest-savannah transition zone of Ghana

Background Low soil fertility is recognized as the major constraint to food production and food security in Ghana. An important practice that restores some level of fertility is long fallow, however this is no longer practiced due to increased pressure on land for other purposes. This has resulted in decline in crop yields in areas (forest-savannah transition zone or Sub-humid ...

Prevention of stack corrosion under wet flue gas desulfurization conditions in a coal-fired power plant: performance analysis and comparative study

Background This study investigated the prevention of stack corrosion under wet flue gas desulfurization conditions in a coal-fired power plant. The performance analysis and comparative studies of six materials for the prevention of stack corrosion were investigated. Results The ion chromatography analysis showed the acid condensation contained fluoride, chloride, nitrate, sulphate, ...

Heuristic assessment of bridge scour sensitivity using differential evolution: case study for linking floodplain encroachment and bridge scour

Background Stakeholders are often required to make judgments and decisions about the tradeoffs between multiple competing objectives inherent in any engineering design. Design optimization can provide decision support for such situations, but often prescribes that only a single design solution be selected for a given set of preferences. The purpose of this study is to frame an ...

Monitoring and modeling the dispersion of produced water on the Scotian Shelf

Background Produced water from offshore oil and gas platforms is often disposed of directly into the sea, and there has been concern that this discharge might have deleterious effects on the marine environment. To help understand the patterns of dispersion and dilution of produced water discharges, and their potential effects, a combined modeling and monitoring study was conducted. ...

Assessment of soil fertility status of Vertisols under selected three land uses in Girar Jarso District of North Shoa Zone, Oromia National Regional State, Ethiopia

Background Land use changes from forests to farmland and grazing land and subsequent changes in soil physical and chemical properties that results in soil fertility decline are widespread activities in Ethiopia. Particularly, this is the most practiced activities in highland areas of the country. The objective of this study was to assess the soil fertility status of Vertisols under ...

Pesticides exposure and the use of personal protective equipment by cocoa farmers in Ghana

Background The hazards of pesticide exposure have been a growing concern globally. The increase of susceptibility of farmers to pesticide intoxication is due to lack of knowledge regarding safe and proper pesticide handling. The aim of this study was to evaluate cocoa farmers’ pesticide exposure by assessing the ways in which they store pesticides, operational habits exhibited ...

The outlook of Ethiopian long rain season from the global circulation model

Background The primary reason to study summer monsoon (long rain season) all over Ethiopia was due to the atmospheric circulation displays a spectacular annual cycle of rainfall in which more than 80 % of the annual rain comes during the summer season comprised of the months June–September. Any minor change in rainfall intensity from the normal conditions imposes a severe challenge ...

Rural households’ agricultural land vulnerability to climate change in Dembia woreda, Northwest Ethiopia

Background Climate change is one of the greatest environmental threats facing our world in recent decades.
