ABSTRACT: The present study assessed solid waste management practices and impact on Ala River water quality in Akure, Ondo state, Nigeria. The primary data were obtained through field observation, interviews and questionnaire while secondary data were obtained from desk review of use of journals, articles, seminar papers, internet sources, government official publications. Simple random sampling technique was used to obtain required information for the study. Results showed that 37.8% of the...
Comprehensive Logical framework of project on Capacity Building for youth on waste management
Water scarcity remains a major development challenge in Kenya and particularly in the Arid and Semi-Arid lands (ASALs) like the Machakos County. Existence of few dams like Muooni dam, near the Kathiani market, has failed to deliver sustainable supply of water to the Mitaboni residents. Despite the emergence of small-scale water harvesting technologies, 54% of the households in Mitaboni still take more than one hour to carry water to their homes. This study sought to assess the existing small-...
Human activites have shaped the world over the years. Survival instincts prompted early man to explore his immediate natural surroundings and try many plants, animal products and minerals to develop a variety of therapeutical agents. W.H.O currently encourages, recommends and promotes research and inclusion of herbal drugs into national health care programmes. Indiscriminate destruction of forests and wood lands has led to reducing biodiversity that is increasingly causing disappearance of in...
Information on pesticide residue occurrence in hive products is scanty or lacking yet it is important so as to safeguard human health from effects of pesticides. The aim of the study was to identify and quantify neonicotinoid residues in hive products. The study was undertaken for 6 months between (March-August, 2015) at Kiambu and Nairobi Counties. The objectives of the study were to find out the pesticides used in the cultivation of crops, the frequency of use and the concentration of neoni...
The study sought to find out the climate change effects on food security, and the community coping strategies in Gikindu Division in Murang’a County. The study was in response to the profound climate change effects over the years leading to depressed rainfall and increased temperatures exposing the farmers to the risk of diminished returns from the production activities. Gikindu area sits on a low agro-ecological zone five and six which is prone to persistent crop failure attributed to the ...
Agriculture sector in Kenya has remained pivotal to the national economy with a direct relationship between its performance and overall national economic growth. Agricultural production is nonetheless constrained by various diseases, insect pests, and low soil fertility thus necessitating mitigation by use of agrochemicals which are, however, potentially harmful to man and the environment. The broad objective of this research was to assess the human and environmental health risks posed by t...
Plant genetic resources are a key component of global biodiversity from which humanity derives most of its food and other essential goods and services. An understanding of the extent, distribution, and patterns of genetic variation is useful for several purposes, including selection for conservation, estimation of any possible loss of genetic diversity prior to conservation programs, understanding the genetic variability available and its potential use in breeding programs, and estimating t...
ABSTRACT Currently the world is embracing renewable energy not only to enhance energy capacity but also to mitigate problems associated with green house gas emissions. North eastern Kenya region lagged behind others parts of the republic in social economic indices. This may be attributed to the fast distance between the region and the electricity generation areas. Therefore northern Kenya is not connected to national electricity grid. Renewable energy from the wind can be used to supply elec...
ABSTRACT Nutrient mining and mismanagement of farmers’ fields has led to a decline in soil fertility in smallholder farms. In order to increase the productivity and subsequently improve food security in Sub-Saharan Africa (SSA), there is a need to identify soil nutrients limiting maize growth and production. The objectives of the study were; (i) to determine the most limiting nutrients for maize production in Kandara and establish the effect of selected soil amendments (CaMgS, manure and ...
ABSTRACT Plastic waste material continues to present environmental challenges throughout the world. Of greatest concern is their disposal in agricultural soils where they interfere with soil fertility due to its inability to decompose fast. Specifically, the research examined under experimental conditions the crop germinative emergence of (Zea mays L.) and finger millet (Eleusine coracana (L.) Gaertn) as affected by plastic waste material commonly disposed in urban and rural environments of...
ABSTRACT One of the major challenges to sustainable use of wetlands is lack of awareness by communities on the values of these ecosystems. Wetland resources are important for socio-economic, cultural and ecological supply of goods and services. Despite their importance, wetlands have remained unprotected and they are exploited beyond what they can endure. The main objective of the study was to establish the effects of natural resource based conflicts on community livelihoods in Ol‟Bolossat...
ABSTRACT One of the greatest environmental challenges in the 21st century is ensuring successful implementation of participatory community based waste management practices in cities particularly in slums and informal settlements. This study aimed at investigating the relationship between socio-economic exclusion and community based waste management practices in Kibera informal settlements, Nairobi County. To achieve the study objectives this study was guided by Marxist theoretical framework o...
ABSTRACT Fresh water bodies constitute a vital component of a wide variety of living environments as integral water resource base in many human societies in the world. Water hyacinth has invaded Freshwater systems in over 50 countries on five continents and changes to its density have the potential to affect other ecological and human communities in areas where it is established either positively or negatively. The hyacinth, since its introduction in Kenya, has been a menace to the riparian c...
ABSTRACT Contamination of fresh water sources with heavy metals found within the agricultural areas is largely contributed by amongst other factors, application of inorganic fertilizers and pesticides. Removal of heavy metals from the contaminated waters using conventional methods is cost prohibitive and more importantly less effective especially when concentration of heavy metals is low. As a result, use of alternative technologies such as phytoremediation is being promoted. Phytoremediation...
