The standard deviation (dispersion sorting) values range from 1.38 – 2.48 i.e. poorly to moderately sorted with an average value of 1.805Φ. The studied sa...

Implications Of Consumption Of Unrecorded Alcohol On Sustainable Lifestyles Amongst Households In “Shauri Yako” Embu County

ABSTRACT Living sustainably is apparently the ultimate objective in the cosmos for the resilience of all biotic and abiotic phenomena. Paradoxically, sustainable lifestyles envisaged in sustainable development goals (SDGs), are almost an unfeasible end. Consumption of unrecorded alcohol is hypothesized in this study to be a major inhibitor to attainment of sustainable lifestyles. This study therefore, conducted in Embu County at Shauri “Yako,” sought to find out the effects of consumption...

Effectiveness Of Rainwater Harvesting As A Strategy For Flood Mitigation In Ruai Area, Nairobi County, Kenya

ABSTRACT Harvesting of rainwater is a strategy which primarily benefits the local human livelihoods and ecosystems. Ruai has gone through development boom and densitification, increased infrastructure such as roads, both single and multi dwellings leading to changes in the physical characteristic of the area hence increased surface run-off. Further Ruai and its environs are flat hence encouraging flooding .There has been a range of incidences of flooding in the area causing loss of property, ...

Socio-Economic Attributes Hindering Adoption Of Alternative Crops To Tobacco Farming In Kehancha Division, Kuria West Sub-County, Kenya

ABSTRACT Studies have documented many negative social, economic and environmental implications of tobacco farming. Tobacco farming puts an extra stress on ecosystems and causes specific health and socio-economic problems for poor populations engaged in the activity. Through research, environmentally friendly and sustainable alternative crops to tobacco farming such as soya beans, watermelons, sweet potatoes, groundnuts, cabbages, among others, have been identified. However, the rate and ...

Effects Of Inorganic And Organic Fertilizers On Nutrient Uptake, Soil Chemical Properties And Crop Performance In Maize Based Cropping Systems In Eastern Province Of Rwanda

ABSTRACT The Eastern province of Rwanda is highly populated. This has led to continuous cropping systems without addition of external fertilizers to compensate losses due to removal of grains and residues through harvesting. In such conditions, soil fertility decline is a major factor limiting per capita crop production in the area. It is quite difficult for smallholder farmers to afford to buy and apply adequate quantities of mineral fertilizers and organic sources, making it difficult for t...

Integrating Indigenous And Conventional Knowledge-Based Climate Forecast For Farmers’ Enhanced Adaptation To Climate Variability In Tharaka-Nithi And Kitui Counties

ABSTRACT Climate variability has a negative impact on crop productivity and has affected many small-holder farmers in the arid and semi-arid lands (ASALs). Small-holder farmers in the study area are faced with the constraint of climate variability and have consequently made effort at the local level to utilize indigenous knowledge (IK) in addition to conventional knowledge to mitigate the impacts of the variability. However, documentation of the IK indicators is limited. This study was theref...

Assessment Of Radiological Doses Associated With Natural Radioactivity From Soil In The Communities Close To Uranium Mines In Namibia

ABSTRACT Primordial radionuclides are ubiquitous in the environment and they exist in different ranges of concentration levels in minerals. Some human activities such as uranium mining can result in a rise of concentration of naturally occurring radioactive materials (NORM) and lead to exposure conditions. This necessitates a need to radiologically map and determine the extent of exposure of people who work in the mines and communities that live nearby as they can be the primary exposed popu...

Improving Agronomic Efficiency In Cassava- Based Farming Systems In The Democratic Republic Of Congo Using Organic And Inorganic Inputs.

ABSTRACT Cassava is an important food crop in small-holder farming systems in DR. Congo. Due to the limited use of organic and inorganic inputs, soil fertility becomes a major problem in cassava production systems. Inorganic inputs for small-holder farmers are often too expensive to apply at optimal rates and combining use of organic and inorganic fertilizer inputs is a suitable management principle for small-holder farmers. A study involving 15 households was carried out in DR. Congo with th...

Assessment Of Naturally Occurring Radioactive Materials And Trace Elements In Playgrounds Of Selected Basic Schools In The Ga East Municipal District, Accra, Ghana

ABSTRACT The 235U, 232Th series and natural 40K are the main source of natural radioactivity in soil and have long half-lives up to 1010 years. Therefore their presence in soils and rocks is simply considered as permanent. Also due to rapid urbanization, most of Basic School playgrounds in Accra are built close to major roads or industrial areas for which they are subject to many potential pollution sources, including vehicle exhaust and industrial emissions.. A study has been carried out on...
