Evapotranspiration (ET) plays a crucial role in integrated water resources planning, development and management, especially tropical arid regions. Determining ET is not straightforward due to the heterogeneity complexity found real-world hydrological basins. This situation often compounded regions with limited hydro-meteorological data that are facing rapid of irrigated agriculture. Remote sensing (RS) techniques have proven useful this regard. In study, we compared daily actual estimates...
Multi-stakeholder platforms (MSPs) have gained momentum in addressing contentious and cross-sectoral aspects of natural resources management. They helped to enhance cross-learning the inclusion marginalized groups. Tanzania’s water management sub-sector has championed these as a means breaking silos around planning, coordination, resource mobilization. However, it is not uncommon experience occasional dominance some influential sectors or groups due their contribution process, contemporary...
Inadequate knowledge on actual water availability, have raised social-economic conflicts that necessitate proper management. This requires a better understanding of spatial-temporal trends hydro-climatic variables as the main contributor to available for use by sectors economy. The study has analysed trend viz. precipitation, temperature, evapotranspiration and river discharge. One downstream gauge station was used discharge data whereas total 9 daily observed 29 grided satellite stations...
Abstract We explore seasonal variability and spatiotemporal patterns in characteristic drainage timescale ( K ) estimated from river discharge records across the Kilombero Valley central Tanzania. values were determined using streamflow recession analysis with a Brutsaert–Nieber solution to linearized Boussinesq equation. Estimated variable, comparing between wet dry seasons for relatively small catchments draining upland positions. For larger through valley bottoms, typically longer more...
Uncertainty analysis has become the standard approach to hydrological modelling, but yet be effectively used in practical water resources assessment. This study of Great Ruaha River basin Tanzania is based on use regional estimates mean runoff, groundwater recharge and three flow points duration curves (FDCs) constrain ensemble outputs from Pitman monthly model using Monte Carlo parameter sampling. The constraint bounds were quantified gauged data available for 26 sub-basins together with...
In order to cope with a severe reduction of the raingauge network in Great Ruaha River basin over past 30 years, an interpolation scheme using spatial patterns from satellite images as covariate has been evaluated. The regression-based attempts combine advantages accurate rainfall amounts records unique pattern information obtained satellite-based estimates. A analysis reveals that simple sparse current compares very poorly originating much denser historic network. contrast, datasets include...
Water scarcity and nutrient availability for rice farming have become great matters of concern in the contexts climate change land use globally. Both interact contribute to crop productivity at expense nutrients future water sustainability. The objective this study was understand on-farm potential response soil organic carbon (SOC), total nitrogen (TN), phosphorous (TP) management practices within Kilombero Valley, Tanzania. Soil samples were collected from three villages area four depths:...
The preservation of soils which provide many important services to society is a pressing global issue. This particularly the case in countries like Tanzania, will experience rapid population growth over coming decades. country also currently experiencing land-use change and increasing intensification its agricultural systems ensure sufficient food production. However, little known regarding what long term effects this land use be, especially concerning soil quality. Therefore, we assessed...
Information on aquifer processes and characteristics across scales has long been a cornerstone for understanding water resources. However, point measurements are often limited in extent representativeness. Techniques that increase the support scale (footprint) of or leverage existing observations novel ways can thus be useful. In this study, we used recession-curve-displacement method to estimate regional-scale transmissivity (T) from streamflow records Kilombero Valley Tanzania. We compare...
Abstract This review provides an assessment of the evolution hydrological modelling for Eastern Africa. We outline historical development and perspectives considered as this region, like many regions around world, sees increasing attention on how water resources can be sustainably developed. emphasize spatial scales approaches that typify region these have changed with time. The is done in two complementary approaches. first approach to explore a practical, real-world example providing...
Climate variability and change has led to multifaceted stresses compounded socio-environmental problems. Using the example of Simiyu wetlands in Tanzania, this article analyses complexity inter-connectedness climate-related mal-adaptation coping strategies their implications. Various study methods were used, including consultative meetings, stakeholders workshops, a literature review, household questionnaires land use cover analysis. Reactive adaptation have resulted increased risks...
