Farmers in Laikipia West district like many other farmers living in wildlife dispersal areas have continued to suffer huge losses resulting from wildlife menace without adequate compensation. Land use has been changing with time making the area prone to crop destruction by elephants. While it is known that land use change contributes to human -wildlife conflict, it has never been quantified over time for Laikipia West District. The objective of the study was to assess changes in land use...
ABSTRACT The overall objective of this study was to assess the economic impacts of climate change on agriculture in Kenya’s coastal region. To achieve this, specific objectives were used: to assess which impact climate change has on crop net revenue; to evaluate the impact of climate change on livestock net revenue; and to estimate the impact of climate change on combined net revenue. The study was conducted in all the six counties in the coastal Kenya: Kwale, Mombasa, Kilifi, Lamu, Tana Ri...
ABSTRACT Climate change due to anthropogenic induced global warming is one of the greatest and defining challenges of the current and future centuries. The Intergovernmental Panel on Climate Change (IPGC) has unequivocally affirmed it and directly linked it to anthropogenic Green-House Gases (GHGs) emissions from fossil fuel burning and land use changes. Although the impacts of climate change are global, they will be differently felt and distributed among different regions, generations, age ...
ABSTRACT A growing fish demand in Kenya, coupled with Government support from the Government has seen an upsurge in the aquaculture sub-sector. The Government’s Economic Stimulus Programme (ESP) has been the main boost to Aquaculture development in the country. Despite the high growth, there is inadequate information on impact of the growth in aquaculture on water quality and livelihoods. The main objective of this study therefore was to establish the quality of water in the fish ponds and...
ABSTRACT Quarrying for limestone is an economic necessity that is not only hazardous to human but also one that invariably has deleterious effect on the environment. Information on the performance of trees species is important as plants are key in the revegetation of exhausted quarries. A comparison of field performance of Acacia xanthophloea, Schinus molle, Casuarina equisetifolia and Grevillea robusta was made in an exhausted limestone quarry, backfilled with limestone mine waste, in a semi...
ABSTRACT Post-harvest fisheries activities have been cited as contributors to environmental degradation. The current sanitary situation in urban fish markets is worrying and present threats to the public health and the surrounding environment. The research aimed to investigate and understand how the fish trader’s activities influence the environmental situation in fish markets. A descriptive survey design was used for the research. The target for the study was the fish traders of Gikomba fi...
ABSTRACT Commercial oil and gas was discovered in Kenya in 2012. Few academic studies have been done on the effects of the mentioned discovery to the environment.The oil and gas resources are expected to transform the economic wellbeing of the locals and the nation at large.However,land degradation, environmental pollution and socio-economic problems have always ensued oil and gas exporation ventures globally.This study aimed at determining the effects of oil and gas exploration on biophysica...
ABSTRACT Yushania alpina formerly known as Arundinaria alpina is the only species of native bamboo indigenous forests in Kenya. It plays an integral part in the indigenous forests in which it occurs. Bamboo is a fast growing, renewable, widespread, low cost, environment enhancing resource with great potential in environmental conservation and poverty alleviation. The lack of rules surrounding bamboo exploitation in Kenya has resulted in unsustainable harvesting and utilization of bamboo. Ther...
ABSTRACT In Sub-Saharan Africa, acidic soils occupy 29% of the total area, while about 13% of the Kenyan total land area has acidic soils, widely distributed in croplands of the central regions. The high soil acidity coupled with soil nutrient depletion negatively affect performance and yields of maize in the region. This study was therefore carried out at Kirege in Tharaka Nithi County for two cropping seasons; short rains (SR) in 2016 and long rains (LR) in 2017 to determine the effects of ...
Abstract Information on seed germination of trees is important as it forms a vital baseline for among other information on the germination of indigenous seedlings which take many years to germinate. The study was carried out to find out the effect of different light intensities and growth hormone on the propagation of Ocotea usambarensis Engl.The study was carried out for a period of three months (August to October 2010). The objective of the study was to determine the best propagation method...
ABSTRACT Fisheries and aquaculture is an important source of food, income and livelihoods for hundreds of millions of people around the world. Aquaculture production has increased from 29.5million tonnes in 2010 to37.5 million tonnesin 2014 in the world and 1.3 million tons in 2010 to 3.8 million tonnesin Africa. There is no sufficient information suitability ofwater quality in aquaculture ponds in Tigoni. The aim of the study wasto determine the suitability of aquaculture ponds for fish fa...
ABSTRACT Agro-industrial industries are among of the major contributors of industrial effluent. Poor management of these effluents has resulted in myriad challenges to developing countries on environment and human health. The research was conducted in Bomet County of Kenya. The study sought to assess the impacts of effluent discharge from Kapkoros Tea Factory into Kipsonoi River on the local community. The objectives were: to identify types of wastes generated by the Kapkoros Tea Factory, to ...
ABSTRACT Research in wetlands has made great progress and it is widely recognized globally that they are under threat of disappearing and degradation due to overexploitation of their products and services. The study was undertaken in Yala wetland that covers an area of 17,500 ha in an area with one of the highest population density and growth rate in Kenya. The wetland is mainly cleared for crop cultivation and settlement and about 2,800ha (Figure 4.14) have been drained for commercial agricu...
ABSTRACT Land-use changes are the main cause of human and environmental problems especially in many developing countries in Africa and Asia. Study was conducted in Mai Mahiu, Nakuru County, Kenya whose aim was to assess the impacts of land-use and cover changes on the ecosystem functioning and human environment. Specific objectives were: (i) to understand the nature of land use practices (ii) to monitor impacts on soil quality; (iii) impacts on vegetation composition and structure; (iv) to e...
