ABSTRACT Organic manure supply to soil with inorganic or on its own is good soil management practice improving crop quality and overall soil fertility. Increasing water demand on many sectors and evident reduction of water allocated to agriculture is of importance prompting exploration of the more efficient water use techniques to maximise production. Local small holder communal farmers are faced by challenges of lack of access to inorganic fertilizers due to economic constrain and lack of ca...
ABSTRACT Groundwater (GW) use for irrigation by smallholder farmers has been proposed as a solution to increasing water scarcity in the Usangu Plains, Tanzania. This study evaluated the financial viability of utilising GW for irrigation by smallholder farmers in the plains. Specifically, the study analysed the costs and benefits of using GW for small scale irrigation, examined the socio-economic factors influencing the use of GW for irigation, and assessed the financial affordability of small...
ABSTRACT A feeding trial was conducted with 48, four weeks old growing indigenous chickens to study the optimum inclusion level of toasted velvet bean meal. Four isonitrogenous (16% crude protein), iso-energetic (2857 kcal/kg) with similar crude fibre (15%) diets were formulated. The diets incorporating graded levels (0, 10, 20 and 30 %) of toasted velvet bean seed meal were fed for 42 days in a completely randomized design. The birds were randomly allocated to four dietary treatments, each t...

ABSTRACT Open spaces in cities like Dar es Salaam are facing problem of encroachments and conversion for residential and or commercial land uses. Many studies have been done to address the failure of the “top-down approach” by the government authorities and recommended participation and empowerment of local community around the open spaces. However, the state of awareness, perceptions and willingness of local community towards participation in conservation of open spaces (COSP) was still ...
ABSTRACT Land-use and land-cover changes have an effect on the water balance as well as water yield of catchments in Zimbabwe. Most of these changes can be attributed to economic activities undertaken by communities within the catchments in an effort to improve their standards of living. The research was carried out in Insiza dam-catchment to investigate the effects of temporal land-use and land-cover changes on Insiza dam-catchment water balance. GIS and Remote sensing techniques were used i...

The villages namely Usanganya, Mole and Tutuo were involved. Household questionnaire, checklists, participant...
ABSTRACT Pugu Forest Reserve is a coastal forest covering an area of 2,410 hectares; but has been significantly altered by on-going extraction and conversion to other land uses which releasing carbon dioxide into the atmosphere thus making the forest a net emitter of the greenhouse gases. Though some empirical data exist regarding carbon storage in African coastal forests, little has been done to assess and quantify the carbon stocks and emissions associated with deforestation and/or degradat...
