Box 776, Bulawayo, Zimbabwe d Minerals Resources Centre, University of Zimbabwe, P.O. Box MP167, Mt. Pleasant, Harare, Zimbabwe Abstract The Mzingwane River is a sand filled channel, with extensive alluvial aquifers distributed along its banks and bed in the lower catch- ment. LandSat TM imagery was used to identify alluvial deposits for potential groundwater resources for irrigation development. On the false colour composite band 3, band 4 and band 5 (FCC 345) the alluvial deposits stand out as white and dense actively growing veg- etation stands out as green making it possible to mark out the lateral extent of the saturated alluvial plain deposits using the riverine fringe and vegetation . The alluvial aquifers form ribbon shaped aquifers extending along the channel and reaching over 20 km in length in some localities and are enhanced at lithological boundaries. These alluvial aquifers extend laterally outside the active channel, and individual alluvial aquifers have been measured with area ranging from 45 ha to 723 ha in the channels and 75 ha to 2196 ha on the plains. The alluvial aquifers are more pronounced in the Lower Mzingwane, where the slopes are gentler and allow for more sediment accumulation.

The alluvial aquifers form ribbon shapes covering over 20 km in length, generally less than 1 km in width and areal extents ranging from 100 ha to 255 ha in the channels and 85 ha to 430 ha on the flood plains. The study area is the lower Mzingwane River, downstream of Zhovhe Dam for a stretch of approximately 50 km. Five commercial agro-businesses use alluvial groundwater for citrus, wheat, maize and vegetable production. The water is abstracted from boreholes and well-points in the river and on the banks. These large users are resupplied by release of water from Zhovhe Dam, which recharges the aquifer.

  • Soil–Water Conservation and Rainwater Harvesting Strategies in the Semi-Arid Mzingwane Catchment, Limpopo Basin, Zimbabwe
    Physics and Chemistry of the Earth 31 (2006) 893–900 www.elsevier.com/locate/pce Soil–water conservation and rainwater harvesting strategies in the semi-arid Mzingwane Catchment, Limpopo Basin, Zimbabwe Walter Mupangwa a,*, David Love a,b, Steve Twomlow a a ICRISAT Bulawayo, Matopos Research Station, P.O. Box 776, Bulawayo, Zimbabwe b WaterNet, P.O. Box MP600, Mt. Pleasant, Harare, Zimbabwe Abstract Various soil water management practices have been developed and promoted for the semi arid areas of Zimbabwe. These include a variety of infield crop management practices that range from primary and seconday tillage approaches for crop establishment and weed management through to land forming practices such as tied ridges and land fallowing. Tillage methods evaluated in this study include deep winter ploughing, no till tied ridges, modified tied ridges, clean and mulch ripping, and planting basins. Data collected from the various trials since the 1990s show that mulch ripping and other minimum tillage practices consistently increased soil water content and crop yields compared to traditional spring ploughing. Trial results also showed higher soil loss from conventionally ploughed plots compared to plots under different minimum tillage practices. Ó 2006 Published by Elsevier Ltd.

  • Changing Hydroclimatic and Discharge Patterns in the Northern Limpopo Basin, Zimbabwe
    Changing hydroclimatic and discharge patterns in the northern Limpopo Basin, Zimbabwe David Love1, 2*, Stefan Uhlenbrook3,4, Steve Twomlow2 and Pieter van der Zaag3,4 1WaterNet, PO Box MP600, Mount Pleasant, Harare, Zimbabwe 2 ICRISAT Bulawayo, Matopos Research Station, PO Box 776 Bulawayo, Zimbabwe 3 UNESCO-IHE, Westvest 7, PO Box 3015, 2601 DA Delft, The Netherlands 4 Department of Water Resources, Delft University of Technology, PO Box 5048, 2600 GA Delft, The Netherlands Abstract Changing regional and global trends in climate and discharge, such as global warming-related declines in annual rainfall in south-eastern Africa, are likely to have a strong influence on water resource availability, and to increase livelihood risk. It is therefore important to characterise such trends. Information can be obtained by examining and comparing the rainfall and runoff records at different locations within a basin. In this study, trends in various parameters of temperature (4 stations), rainfall (10 stations) and discharge (16 stations) from the northern part of the Limpopo Basin, Zimbabwe, were statistically analysed, using the Spearman rank test, the Mann-Kendall test and the Pettitt test. It was determined that rainfall and dis- charge in the study area have undergone a notable decline since 1980, both in terms of total annual water resources (declines in annual rainfall, annual unit runoff) and in terms of the temporal availability of water (declines in number of rainy days, increases in dry spells, increases in days without flow). Annual rainfall is negatively correlated to an index of the El Niño – Southern Oscillation phenomenon. The main areas of rising risk are an increasing number of dry spells, which is likely to decrease crop yields, and an increasing probability of annual discharge below the long-term average, which could limit blue-water availability.

  • Synopsis and Case Studies
    AN EVALUATION OF CLIMATE AND RUNOFF VARIABILITY AND ASSOCIATED LIVELIHOOD RISKS IN THE MZINGWANE CATCHMENT, LIMPOPO BASIN, ZIMBABWE# David Love1,2*,Stefan Uhlenbrook3, Elisha Madamombe4, Steve Twomlow2 and Pieter van der Zaag3 1 WaterNet, PO Box MP600, Mount Pleasant, Harare, Zimbabwe 2 ICRISAT Bulawayo, Matopos Research Station, PO Box 776 Bulawayo, Zimbabwe 3 UNESCO-IHE, Westvest 7, PO Box 3015, 2601 DA Delft, The Netherlands 4 Research and Data Department, Zimbabwe National Water Authority, Harare, Zimbabwe ABSTRACT Climate change occurs over relatively long time scales, although some acceleration in changes can also be seen in data of the last twenty years. The reasons for the current changes in the climatological variables might be anthropogenic (e.g. greenhouse gas emission) or natural (e.g. solar variability etc.), or most likely a combination of both reasons. An increasing body of evidence shows that greenhouse gas emissions are changing our climate significantly. Climate change is projected to substantially reduce available water (as reflected by projected runoff from a catchment) in many of the water- scarce areas of the world A statistical analysis was carried out of over fifty years of precipitation, temperature and runoff data from several locations in the Mzingwane Catchment – the portion of the Limpopo Basin that falls within Zimbabwe. The trends show declines in precipitation and runoff and increases in maximum and minimum temperatures, across the catchment. The trends observed are comparable to those predicted from some of the global circulation models (GCMs) based on the Intergovernmental Panel on Climate Change Special Report on Emission Scenarios (IPCC (SRES)). Regression analyses show the relationships between climate variability and change and decreasing runoff.
