The Solid Waste Management In Mubaira Growth Point, Chegutu Rural District Council

ABSTRACT Solid waste management has been a topical issue in the urban centres of most developing countries including Zimbabwe. This has posed serious environmental challenges in the cities of Zimbabwe. However, this issue has concentrated on solid waste management in the urban areas leaving out the rural areas. Solid waste generation in the rural areas has since increased both in quantity and quality due to modernization. Solid waste composition in the rural areas has been known to be dominat...

Place Making: A Study Of ‘Oja – Oba’ Open Space Design In Yoruba Urbanism

ABSTRACT Values inherent in city spaces may be biophysical, social, cultural, religious, economic and political. These values give meaning and determine the level of user’s attachment. When urban space generates meanings to city people, the bond is stronger and ‘space’ at that point transforms to ‘place’. While some city open spaces succeed others failed to meet designed goals. This research investigated the inherent ‘place making’ attributes of Oja - Oba open space (King’s ma...

A Grounded Theory Study Of The Implementation Of Spatial Data Infrastructure In Zimbabwe; The Professional Identity Perspective

ABSTRACT Needs for spatial data are increasing due to the different uses it can be put to. Due to the progress in digitalization, the volumes of data in various fields are accumulating quickly at an unprecedented speed. Different types of spatial resources come from different units but they may be integrated effectively through SDI development so that users can easily obtain and apply the shared resources. Spatial Data Infrastructures (SDIs) enable access, sharing and propagation of spatial d...

Deadwood Production And Decomposition Rate Of Acacia Tortilis And Acacia Nilotic Around University Of Dodoma, Tanzania: The Ecological Role Of Termites In Semi-Arid Regions

ABSTRACT Studies on deadwood (DW) production and nutrient recycling through decomposition by termites in semi arid ecosystems are scarce and thus given less consideration in forest management. A study was conducted at Chimwaga forest patch of UDOM to estimate the amount of DW produced by A. tortilis and A. nilotica as well as the decomposition rate by termites during dry and rain seasons. Both random and systematic sampling techniques were adopted coupled with a completely randomized design ...

Assessment Of Species Richness And Relative Abundance Of Small Carnivores In Natural Forest And Shrub Thickets At The University Of Dodoma

ABSTRACTS Urbanization developments results in the loss and fragmentation of habitat, which can significantly alter animal communities. Wildlife species occupying higher trophic levels, such as mammalian carnivores may be especially affected by habitat alteration and concomitant losses of cover and prey. Tanzania has high carnivore diversity, 35 species or more, but relatively little is known about carnivore communities outside protected areas or the effects of urbanization on carnivore comm...

The Role Of Photovoltaic Solar Energy In Enhancing Food Security. The Case Of Pelele Solar Powered Irrigation Scheme In Ward 12 Of Gwanda District

ABSTRACT Access to reliable and affordable energy is a key lever to enhance sustainable livelihoods and an important prerequisite for agrarian economies in Sub Saharan Africa to address food security challenges faced in the region. Limited and unreliable energy supply mainly from conventional energy sources has been a major impediment to increase agricultural productivity in most irrigation schemes in Zimbabwe. Despite having the best solar radiation levels, little research has been conducted...

Phenotypic Characterization Of Local Chicken Ecotypes Indigenous To Semi-Arid Areas Of Dodoma And Singida Regions Of Central Tanzania

ABSTRACT The optimum productivity of local chicken population is limited by poor housing management, poor feeding and nutrition, incidences of diseases and lack of appropriate breeding strategies. A study was carried out in different districts of Dodoma and Singida regions of central Tanzania to characterize local chicken ecotypes based on specific objectives; (1) To identify qualitative traits, and (2) to determine quantitative traits of selected local chicken ecotypes. Chickens indigenous t...

The Effectiveness Of Using A Spectroradiometer In Detecting Coffee Diseases: A Case Study Of Chipinge Coffee Research Institute, Zimbabwe.

ABSTRACT Major economic losses in Agriculture worldwide are reported to be caused by plant diseases, therefore diseases management in an accurate and timely manner is of great importance. This study assessed the effectiveness of using a spectroradiometer in detecting coffee diseases (cercospora, CLR). Healthy and diseased plants were used to compare effectiveness of different indices using a spectroradiometer. Results from this study showed that original data from a spectroradiometer does not...
