ABSTRACT Environmental noise is noise emanating from all other sources except the industrial workplace, main sources include road, rail and air traffic, industries, construction, public works and social activities. WHO and NEMA provides permissible environmental noise level standard to be 75 and 60 dB (A) respectively. Noise pollution has been linked to many adverse health effects and there is limited documentation to this effect within the CBD termini of Nairobi.The aim of this study was to...
ABSTRACT The purpose of the study was to evaluate the contributions of conservation education centres in creating awareness to promote sustainable environmental conservation in schools. In this regard, public education is critical in raising levels of awareness in environmental conservation. The results of this study will contribute to future review and improvement of environmental education and awareness programmes offered by other conservation education centres. A descriptive survey design...
ABSTRACT The recent irregular trends in weather patterns have brought about challenges and opportunities in key sectors of the economy especially in developing countries. Agriculture and tourism are just but examples of these sectors that have been widely impacted by climate variability. Countries as Kenya where agriculture and tourism are the leading earners of the economy has seen a downhill scale in the recent years and climate variability is one of the factors that can held responsible. ...
ABSTRACT Public open spaces form an important part of urban life, giving services to people and protect urban environment. In effective regulations and standards for establishment, setting, management and maintenance of public open spaces have always been a stumbling block in ensuring their sustainability, hence the existence of poorly performing, unplanned, and poorly distributed public open spaces. This study sought to establish why the public open spaces in Machakos municipality, Machakos...
ABSTRACT The thesis resulting from this study intended to investigate factors affecting aloe propagation and cultivation in Kieni West division, Kenya. The rationale for the study was informed by the fact that aloe propagation and cultivation is one of the identified strategies for aloe conservation and management outside protected areas with both ecological and social-economic benefits. The study was based on the awareness that Kenyan aloe species are listed under Appendix II of Conventio...
ABSTRACT Sanitation has been a thorny issue especially in many informal settlements all over the world with the third world countries being highly affected. Therefore people living in these affected areas are exposed to these deplorable conditions. Kenya is not spared either and therefore our informal settlements are suffering from myriad of sanitation related problems that are causing slum residents to be unprotected from all manner of exposures. Since there are a lot of underlying factors ...
ABSTRACT Decline in crop yields in Tharaka-Nithi and Embu counties is linked to poor agricultural practices and climate variability. Research has reported positive results from implementation of mulching, tied ridging, minimum tillage and intercropping. This study was set up to: i) determine effect of soil and water conservation technologies on runoff ii) evaluate effect of the technologies on sediment and nutrient loss iii) investigate effect of the technologies on maize yield, and iv) anal...
ABSTRACT Most of our activities as human beings generate solid waste. As much as the solid waste that is generated may not be harmful in its current state, the methods through which this waste is handled, stored, collected and disposed can pose risks to the local populace as well as the community. The situation is aggravated by the fact that solid waste has no owner, and therefore the provision of quality solid waste management services is left for those who can afford it. The objectives of ...
ABSTRACT Urban farming makes a substantial influence on the household economy of the urban poor especially in developing countries. Urban soil the hot spot of urban farming is a natural sink for contaminants especially the potentially toxic trace elements derived mainly from anthropogenic activities. The sources of trace elements include effluents from sewerage drainage system, unprocessed wastewater from neighboring manufacturing industries in addition to farming activities along polluted r...
ABSTRACT The coffee plant (Coffea Arabica L) originated in the forests of Ethiopia, where it evolved as an understory tree species. Mimicking this native growth habit, coffee farmers have for centuries grown coffee under shade and intercropped with various fruit tree species to provide shade, foods, and income. The impact of these intercrops on coffee production is little known hence the need for this study. The study was carried out in an existing coffee intercropping plot at Coffee Researc...
ABSTRACT Ecosystems are largely dependent on the prevailing climatic conditions. The ever changing climate across the world has necessitated climate change adaptation projects as a coping mechanism to the adverse effects of climate change. The main objective of the study was to assess ecosystem services in climate change adaptation projects in the least developed countries of West Africa. Specifically, the study sought to; (i) assess the ecosystems changes in the Least Developed Countries o...
ABSTRACT Open defecation refers to defecating in bushes, fields, water bodies and other places that are open. Across the world, approximately 1 billion people are practicing open defecation. This is worse in sub-Saharan Africa where about 215 million people defecate in the open. In Kenya, an estimated 5.6 million people practice defecation in the open. The introduction of Community Led Total Sanitation strategy by the Ministry of Health has not achieved its goal of improved sanitation and hyg...
ABSTRACT The activity of the oil prospecting companies in the study area is mainly that of crude oil extraction from the subsurface. As a result of these petroleum activities, there is a continuous destruction of aquatic lives – flora and fauna destabilizing the entire aquatic eco-system. This study was focused on the impact of oil spillage on the water quality. Different physico-chemical parameters were analyzed, including Temperature, Taste, Colour, Odour, Total Dissolved Solid, Conducti...
ABSTRACT Erosion is one of the major environmental hazards currently ravaging the southeastern part of Nigeria, especially Imo-state. This present study was conducted to assess the impact of Umuagor-Urualla gully erosion site. Analysis of undisturbed soil samples collected at three distinct positions (surface, subsurface and base of the gully) showed that the liquid limit and plastic limit for sample 1 was NP (non-plastic), with Plasticity Index of 0%, while the Plasticity Index for samples ...
ABSTRACT African rainforests are lost at a high rate every year and most of the cleared areas are transformed to agricultural land. Such anthropogenic influences potentially result in biodiversity changes of major conservation concern. In ecosystems near Kakamega Forest, the conservation of some fauna depends on their survival in adjacent agricultural lands. Therefore, understanding the biodiversity potential of field margin vegetation or hedgerows and the interior of agricultural fields was...
