ABSTRACT This project examines the rate of vegetation cover changes in Enugu State using NDVI techniques for the year 1991, 2003 and 2015 so as to detect changes that has taken place between these periods. The main goal of this study is to evaluate vegetation cover change of the study area using Normalized Vegetation Index (NDVI) in order to identify vegetation cover and the spatial distribution in the area for the period of investigation and to produce NDVI and spatio-temporal change maps a...
ABSTRACT The indiscriminate location of land uses, rapid and uncontrolled development in urban/rural areas as well as the old and new state capitals in Nigeria have resulted in urban slums, urban sprawl, traffic congestion, blight, obsolescence and overcrowding. Worst still, little or no attention is paid to their orderly growth and the demand they make on the limited land resources. Awka Capital Territory (the study area) as a new site for the New Anambra State Capital is also affected with ...
ABSTRACT Soil erosion is the systematic removal of soil including plant nutrients from the land surface by various agents of denudation. This study intends to examine the community assessment on the social and economic effect of gully erosion on dwellers of Ihube, Amuro and Ugwaku communities in okigwe local government of Imo state respectively. It also intends to identify the percentage of gully erosion area affected in the total land use area of the communities/ villages under study. ...
ABSTRACT This study examined the implementation of Revenue Sharing policy at Bwindi Impenetrable National Park towards improvement of people’s livelihood and support for conservation. Bwindi is a world heritage site and a home of almost 50% of the World Mountain Gorillas. Distributive, procedural, recognitive and contextual dimensions of equitable benefit sharing were explored and analysed. Revenue Sharing policy implementation was regarded as the independent variable while community livel...
ABSTRACT Most changes in forest cover affect the amount of carbon held in vegetation and soil, thereby, either releasing carbon dioxide (a greenhouse gas) to, or removing it from the atmosphere. A study on effects of forest cover change on carbon stock in miombo woodlands was carried out in Mbeya region at Mbiwe Forest Reserve. Landsat MSS, TM and ETM+ image data acquired on June 1984, June 1990 and June 2013 were obtained and used for forest cover change analysis. Inventory data on systemat...
ABSTRACT Fish is an important component of aquatic biodiversity in Tanzania and plays an important role in the national economy. However, the spatial-temporal distribution of fish in the Little Ruaha River Catchments and its contribution to household income have not been given sufficient evaluation. This study determined the spatiotemporal diversity and abundance of fish, generated the information spatial distribution of fish across the catchments and determine the contribution of fish to ...
ABSTRACT Vegetation communities are home to a number of animals including small mammals, hence any change in vegetation communities will influence their abundance and spatial distribution. This study aimed at investigating the influence of vegetation communities on small mammal abundance and diversity in the Isimani agroecosystem landscape, southern Tanzania. Three study sites selected based on landscape characteristics and vegetation communities were investigated, classified and mapped. Fo...
ABSTRACT A study was conducted to classify and establish the fertility status of the soil at the Dakawa Irrigation Scheme (DIS) and subsequent to this, a screen-house pot experiment was conducted to assess the response of rice (variety TXD 306) to nitrogen and phosphorus applied to the dominant soil type at the DIS. According to the Soil Taxonomy and the World Reference Base for Soil Resources, the soil of the study area classified as Inceptisol and Cambisol, respectively. Based on physical,...
ABSTRACT Community-Based Organisations (CBOs) are known to contribute to development especially at the grassroot level. However, the contribution of households in CBOs‟ poverty alleviation has not been given adequate attention in the literature. This study, therefore, examined households‟ level of participation in CBOs‟ poverty reduction programmes in Oyo State, which has the highest number of CBOs‟ in Southwestern Nigeria. Arnstein‟s Ladder of Citizen Participation provided the an...
EXTENDED ABSTRACT Rice production in Tanzania is generally low and continuing to decline partly due to low soil fertility. Smallholder farmers are continuing cultivating in the same area with little or without use of fertilizer due to limited access to costly industrial fertilizers. This trend results into continuous mining of plant nutrients such as phosphorous (P) and other essential nutrients elements which are needed by rice for growth and development; and consequently decline in soil fe...
Depth measurement is Considered as a first goal in hydrographic survey, it depends on different techniques and instruments, it’s most costly procedures. However; some mathematical models are used for condensing depths with a relatively low cost. Artificial neural networks appears and in many applications used to solve real-world forecasting, classification and function approximation problems. It is fast, intelligent and easy to use Neuro Intelligence supports all stages of neural net...
ABSTRACT Despite the positive impact of Acacia mearnsii (Black Wattle) production presented in literature as an alternative source of energy and income for rural poor, the value chain for black wattle in terms of who are the actors along the chain, what value addition activities are performed and economic performance at the main node have received low research attention. This study analysed the value chain of, and its contribution to the rural livelihoods in Njombe and Lushoto Districts. Dat...
ABSTRACT Water is one of the scarce resources very important for the development for humankind hence efficient allocation is needed. Economically, efficient allocation of water is desirable to maximize the welfare of the society that obtains from available sources. The rural population water supply services have been left behind which increase with domestic water demand. There are some initiatives in Moshi Rural District to establish some water projects so as to solve the problem of water sc...
ABSTRACT Human-elephant conflicts (HEC) have been persistent in Ikorongo-Grumeti Game Reserves (IGGRs) and the adjacent communities of Bunda and Serengeti districts, Mara region. This study aimed to identify factors leading to HEC, examine losers and gainers, determine barriers to applied measures and suggest new approaches and techniques for effective mitigation of HEC. Data collection involved direct observations, key informant interviews and household survey using questionnaires. The anal...
ABSTRACT Alien plant are plant species introduced in a new area outside their native range and when spread beyond the place of introduction, they become invasive thereby suppressing regeneration of native plants. There is little empirical evidence explaining the effects of the extent of spread of alien plant on regeneration of native tree species. This study was conducted in Amani Botanical Garden (ABG) to assess the effects of selected alien plants on recruitment of native tree species. A c...
