Application of Gis and Remote Sensing in The Monitoring of Urhonigbe Forest Reserve in Edo State

ABSTRACT The land use/land cover of urhonigbe forest reserve between 1987 and 2015 was analyzed to determine the rate and nature of the land use change over time and their possible effect on the forest ecosystem of Urhonigbe Forest. Satellite Remote Sensing and GIS techniques was applied in monitoring Urhonigbe Forest Reserve in Edo State. The land use change and its effect during the time period (1987-2015) were also determined. Onscreen digitization of the study area maps was employed to d...

Site Criteria in CO2 Capture and Storage

This paper is an overview of criteria needed for the deployment of CCS technology. This to avoid unnecessary leakage in the storage mechanisms. For a CCS to be successful  the criteria must be examined and the site is clear for the technology. This paper give an insight into the basic criteria for the site which will be used for for storage of co2

Influence of Building Envelope Design on Indoor Thermal Comfort of Office Workers in Enugu, Nigeria

AbstractClimate Change and global warming are problems that result to an increase in indoor temperature especially in the tropical region. The adverse effect of rise in temperature has increased the need for indoor cooling in order to improve comfort for building occupants. Building envelope separates indoor spaces from outdoor spaces and is also capable of improving indoor comfort through appropriate balance of passive and active techniques. The contemporary concern is on how to improve the ...

Interview and personal observation were used to collect the data. These data collections were Residents’ Waste Management Methods, Solid Waste Management Attitude Scale, Key Informant Interview Schedule. A mean score of 2.0 and above indicates that the residents are of positive atti...

An Assessment Of The Impact Of Land Use Changes On Human Elephant Conflict In Laikipia West District, Kenya

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...

Assessment Of Economic Impacts Of Climate Change On Livestock And Crop Returns In The Coastal Region Of Kenya

ABSTRACTThe 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 Riv...

Assessment Of Climate Change Impacts On Natural Resources And The Different Gender Among The Pastoralist Communities Of Samburu, Kenya

ABSTRACTClimate change due to anthropogenic induced global warming is one of the greatest anddefining challenges of the current and future centuries. The Intergovernmental Panel onClimate Change (IPGC) has unequivocally affirmed it and directly linked it toanthropogenic Green-House Gases (GHGs) emissions from fossil fuel burning and landuse changes. Although the impacts of climate change are global, they will be differentlyfelt and distributed among different regions, generations, age c...

Influence Of Aquaculture Development On Fish Pond Water Quality And Livelihoods Of Fish Farmers In Gatundu, Kiambu County

ABSTRACTA growing fish demand in Kenya, coupled with Government support from theGovernment has seen an upsurge in the aquaculture sub-sector. The Government’sEconomic Stimulus Programme (ESP) has been the main boost to Aquaculturedevelopment in the country. Despite the high growth, there is inadequate information onimpact of the growth in aquaculture on water quality and livelihoods. The main objectiveof this study therefore was to establish the quality of water in the fish ponds and ...

The Performance Of Selected Tree Species In The Rehabilitation Of A Limestone Quarry At East African Portland Cement Company Land, Athi River, Kenya

ABSTRACTQuarrying 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-...

Influence Of Fish Trade Activities On The Environment In Gikomba Fish Market, Nairobi County, Kenya

Challenges And Opportunities Of Indigenous Bamboo And Its Environmental Conservation In Kieni Forest, Gakoe Location Of Kiambu County, Kenya

ABSTRACTYushania 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. There...

Lime, Manure And Inorganic Fertilizer Effects On Soil Chemical Properties, Maize Yield And Profitability In Tharaka-Nithi County, Kenya

ABSTRACTIn 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 m...

Propagation Of Ocotea Usambarensis Engl. Using Various Methods In Mt. Kenya Forest, Nithi County, Kenya

AbstractInformation on seed germination of trees is important as it forms a vital baseline foramong other information on the germination of indigenous seedlings which take manyyears to germinate. The study was carried out to find out the effect of different lightintensities and growth hormone on the propagation of Ocotea usambarensis Engl.Thestudy was carried out for a period of three months (August to October 2010). Theobjective of the study was to determine the best propagation method using...
