The present study uses a satellite remote sensing approach for assessing coastal sediment dynamics in the western side of Zanzibar channel, Tanzania. Four Landsat images (1986, 1998, 1999 and 2000) were used study. Investigation four revealed that Ruvu delta north river mouth has been growing rapidly, especially between 1986 with an annual northward linear growth rate about 133 m year−1 areal 1 km2 every 3 years. identified palaeo-shoreline feature is parallel to shoreline located 1.9 km...
The Pangani River Basin, with a total area of 43,000 km2 is one the most important Tanzania's river basins. Water and arable land are resources. water balance in Basin estimated at about 900 million m3 per annum. increasing demands to meet various socio-economic needs placing basin under critical stress. Irrigation abstraction evaporative losses Nyumba ya Mungu reservoir major contributor observed stress basin. Deforestation on highlands use traditional environmentally unfriendly...
Shore morphology and nearshore sediments between the Pangani Kipumbwi rivers in coastal Tanzania were investigated. The information was gathered using field observations, sediment sampling of area, interviews with residents. distribution on sea bottom is mainly controlled by bathymetry, sand (medium- to coarse-grained) dominating water depths less than 10 m, silt greater 15 m. Sediments 10- 15-m depth consist a mixture fine silt. carbonate production study area limited high influx...
This paper assesses the perceptions of smallholder rice farmers in Zanzibar on use conventional and indigenous knowledge (IK) for seasonal weather forecasting farming decisions. It draws data from a study that was conducted two fields Central district, Unguja, four Micheweni Pemba. The mainly employs qualitative focus group discussions interviews. results reveal farmers, particularly rain-fed fields, have limited access to forecasts, thus rely traditional forecasting. is ascribed their...
Seagrasses are marine flowering plants found in both temperate and tropical coastal environments, that offer vital ecosystem services adaptations. However, due to their proximity the shore, they heavily impacted by human activities climate change, endangering seagrasses services. To manage seagrass meadows effectively sustainably, detailed monitoring is essential. Unfortunately, past under-prioritization of reliable baseline data impedes understanding dynamics rapid response declines. This...
Coastal community continuity and change in livelihoods become a prime adaptation strategy worldwide because of climate environmental change. The changes environment along the coast have been associated with natural human induced factors. This paper analysed livelihood as measures northern Unguja, relation to temperature rainfall Archival current reviews, interview observation which represent over last 100years were used. also, analyzed how local processes interconnected events 100 years....
