The Last Will Be First: Water Transfers from Agriculture to Cities in the Pangani River Basin, Tanzania
(Water Alternatives, 2012-10)Water transfers to growing cities in sub-Sahara Africa, as elsewhere, seem inevitable. But absolute water entitlements in basins with variable supply may seriously affect many water users in times of water scarcity. This ... -
Porous Polyethylene Composite as Biomass Carrier for Red Pigment Production Using Monosodium Glutamate Wastewater as Medium
(American Scientific Publishers, 2012-10-01)Abundant acidic wastewater from monosodium glutamate production is difficult to treat, leading to serious water pollution. Utilization of monosodium glutamate wastewater (MSGW) with high concentration of COD (33170 mg/L) ... -
The dynamics between water asymmetry, inequality and heterogeneity sustaining canal institutions in the Makanya catchment, Tanzania
(IWA Publishing, 2012-10-01)It has been suggested that the collective action needed for integrated water management at larger spatial scales could be more effective and sustainable if it were built, bottom-up, on the nested arrangements by which local ... -
Design and formulation of nano-sized spray dried efavirenz-part I: influence of formulation parameters
(Springer Nature Switzerland AG., 2012-10-25)Efavirenz (EFV) is one of the first-line antiretroviral drugs recommended by the World Health Organisation for treating HIV. It is a hydrophobic drug that suffers from low aqueous solubility (4 μg/mL), which leads to a ... -
Biodiesel production by sulfated mesoporous titania–silica catalysts synthesized by the sol–gel process from less expensive precursors
(Elsevier, 2012-11-21)A sulfated titania–silica composite (S-TSC) was obtained through surface modification of mesoporous titania–silica composite synthesized using less expensive precursors; titanium oxychloride and sodium silicate as titania ... -
Towards Sustainable Ecotourism through Stakeholder Collaborations in Tanzania
