ABSTRACT Environmental degradation poses a major threat to the existence of humanity today both in rural and urban settlements. In such a scenario, the importance and need for environmental education as a tool for environmental management and conservation cannot be overemphasized. To raise environmental literacy level among Kenyans, Environmental Education is taught using both interdisciplinary and multi-disciplinary approaches. Research has shown that students in urban centers are more envir...
ABSTRACT In Kenya, the forest ecosystem has undergone such considerable degradation that the country’s forest cover is only 3% of the total land area, way below the internationally recommended level of 10% cover. From independence, only the government was involved in forest management. Despite this, the country’s forest cover continued to deteriorate. To stem this decline, the Kenyan Government enacted the Forests Act, 2005, which allows for the participation of both government and commun...
ABSTRACT The study was on woodcarving and basket weaving handicrafts among the Kamba community in Wamunyu and Katangi locations of Mwala District of former Machakos District in Kenya. It examined the extent to which the two practices have impacted on the raw materials used in the production of the respective crafts. A total of 200 craftspeople (100 woodcarvers and 100 basket weavers) participated in the survey. These were purposively sampled for the reason that in each location, the target re...
ABSTRACT Iron industry in Kenya is dependent on imported raw materials. Local deposits of iron ore have been identified at various places in the country but not much has been done to determine whether the deposits are viable in quantity and quality for commercial exploitation. The location and delineation of the iron deposits and formation in the Mbeu area appraises the potential of such mineralization. Ground magnetic survey of Mbeu area was conducted to investigate subsurface geology on the...
ABSTRACT Urban agriculture plays a significant role in national development by contributing towards food security, employment creation, poverty alleviation, and ecologising the “artificial” urban systems. However, it is associated with diverse negative impacts to people and the biophysical environment. Further, though generally illegal in Kenya, the practice continues unabated, being a survival strategy for the low income bracket. This study aimed at assessing its status with view of enco...
ABSTRACT Food insecurity is a major development problem that is caused by myriad of factors in the global, regional, national and local spheres of human life. Several efforts have been put in place to alleviate food insecurity globally, nationally and even locally. Despite these efforts, the situation continues to prevail and sometimes even increase in the contemporary human society. It is therefore imperative that food insecurity gets addressed appropriately. Small scale farmers play a vital...
ABSTRACT Malaria in sub-Saharan Africa is transmitted mainly by Anopheles gambiae Complex mosquitoes. One way of controlling these vectors is by targeting their aquatic stages, which is anticipated to cause significant reduction in adult vectors, hence in malaria transmission. Use of insect growth regulator, Pyriproxyfen, is one potential way of controlling malaria vectors. This study set out to determine the nymphocidal activity of Pyriproxyfen on non-target aquatic dragonfly nymphs during i...
xiii ABSTRACT Climate variability is an emerging phenomenon that is threatening dairy farming globally. The dairy-climate change dilemma in Kenya cannot be mistaken. However, extensive research into dairy farming and an understanding of the dynamics of climate variability effects is greatly lacking.The study investigated the effects of climate variability on dairy farming in Masaba North Sub-county of Nyamira County, Kenya. The main objective was to determine the effects of climate variabilit...
ABSTRACT Low crop yields due to low erratic rainfall, high evapotranspiration, and deteriorating soil fertility in smallholder farmers‘ fields of sub-Saharan Africa have led to a quest for sustainable production practices with greater resource use efficiency. To alleviate water stress, soil fertility decline and reduce runoff, water harvesting technologies and integrated soil fertility management (ISFM) are alternative promising options whose impact on agricultural productivity are not yet ...
ABSTRACT The evaluation of sandstone properties in parts of the Anambra Basin was undertaken to identify the spatial distribution of textural, petrophysical and mineralogical properties of sandstone bodies in the area in order to assess their potentials to host hydrocarbons. Sandstone units from Nkporo Formation, Mamu Formation, Ajali Sandstone and Umuna Sandstone were subjected to textural analysis using sediment granulometry, thin-section petrography and geochemical analysis. Following the...
ABSTRACT The study was carried out between October – November 2008 and aimed at applying Geographical Information System (GIS) approach in characterizing, classifying and making suitability recommendations of soils in Ohia Nekechi within Amasiri area, Afikpo north, Ebonyi State. This study site was identified in a farmland consisting of a toposequence some meters away from Okposi road, Amasiri. A transect was cut across the toposequence revealing its North facing and the South facing slope...
ABSTRACT Characterization, classification and evaluation of some Wetland soils of Oguta, Imo State Southeast Nigeria were executed. The aim was to have baseline information that will assist farmers and other land users in well informed decision making. Four profile pits was dug on the study area Osse moto Oguta. Free sampling technique was used. With the aid of Global Positioning System (GPS) and soil sampling tools. Soil samples were collected based on the FAO guidelines for profile descrip...
ABSTRACT The study is on the characterization and depositional environment of upper Cretaceous sediments exposed at the Ihube-Ikpankwu Axis, Okigwe. The results of field and laboratory studies on selected samples of the study area show that the sediments in the study area are fine to medium grained, with an average mean size of 1.808Φ. 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...
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...
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, ...
