The research used monthly GRACE satellite data from 2004-2010 with a spatial resolution of 20*20 kilometres. The research was aimed at using remote sensing to unravel the groundwater scenarios under different landcover/landuse types in the middle Save catchment of Zimbabwe. 42. the SADC Groundwater Information Portal and the GGRETA Information Management System. Geomatics, Natural Hazards and Risk 1, 3–18. This special issue is now open for submission. Groundwater: the processes and global signi?cance of aquifer degradation. Discrepancies can be However, in Zimbabwe there is limited information on spatial and temporal variability in groundwater storage due to inadequacy of monitoring stations. presentation we will describe recent GRACE enabled science, GRACE Experiment (GRACE) has demonstrated an unequaled ability to monitor This will enable evidence-based planning for the sustainable use of the water resources. Groundwater Crisis in Zimbabwe Brought On by Droughts . Water Resour Res 42. The estimated groundwater … Hay, J., & Mimura, N. (2010). Zimbabwe: Landuse in Dry Tropical Savannas Water resources. The estimated groundwater potential is between 1 and 2 km3/year. The seasonal pattern Groundwater Resources of Northern Ghana: Initial Assessment of Data Availability. University of Zimbabwe, Zimbabwe. Cham: Springer. e-mail: chmn-cgwb@nic.in . Paths in Shallow Aquifers in Zimbabwe. Severe depletion and pollution of groundwater resources are of rising concern in the Upper Manyame Sub-Catchment (UMSC); Zimbabwe's most urbanised sub-catchment. the first effort to estimate groundwater storage changes within a much It is now time to question the long-term viability of groundwater development within the basement aquifers in Zimbabwe given the uncertainty in groundwater resource, the complexities of the climate-groundwater interactions and the projected demands of a growing rural population. Because mean annual rainfall is generally low in Zimbabwe and the rivers … The construction of many wells was mainly financed by the households themselves. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Lambert Academic Publishing (LAP), Germany. The results show that the average monthly and seasonal groundwater levels in Zimbabwe are declining with more seasons and months recording below average levels. The data was then entered into SPSS to review trends and facilitate correlation analysis with actual groundwater data. The results showed that grasslands occupy 59% of the land area, forests occupy 22% of the place and shrublands cover19% of the study area. Disaster risk reduction in the context of climate change and SDGs Thus this study, aims at coming up with a method that can be used to assess groundwater levels from a remote sensing platform. When gravity increases, in this case due to the presence of a mass of ground water, the first satellite to approach this mass will feel a slightly larger gravitational pull than before because of the additional mass of water and the satellite accelerates. Dube, K., Nhamo, G., & Chikodzi, D. (2021). It then examines the key reasons the resource has proven so difficult to manage and concludes that, in many cases, the most promising solutions may lie outside the groundwater sector and within a broader approach to resource systems. Like a fourier series, the sum of the spherical harmonic series represents a sum of sinusoidal functions with wavelengths from the longest (the circumference of the Earth, 40,000 km) to the smallest (40,000 km/maximum degree), which is 600 km in this case [, The pair of satellites was launched in 2002 and the mission was supposed to have a 5 year lifespan but is still operational on an extended life [, The area of study includes the whole of Zimbabwe and analysis will be done by catchments because it has been proven that catchment wide analysis of water resources makes more sense than point analysis [, i. Habitat III: New Urban Agenda. However, technical and human capacities in hydrology are declining as noted by the reduction in the number of meteorological and hydrological stations in Africa during the past 30 years [, Collecting, processing and analysing groundwater data is thus the first step towards assessment of the current state, anticipating changes and forecasting trends in its quantity and quality due to natural processes and human impacts in time and space, providing information for improvements in the planning, policy and management of groundwater resources [, Thus, it is imperative to develop methods for predicting groundwater patterns where they are not directly measured. Furthermore, the need to come up with methods for prediction of ungauged basins has been recognised as a research agenda for the coming decade by the International Association of Hydrological Sciences [, In Zimbabwe, most groundwater measurements are taken from point sources by taking readings of water levels in of wells, trenches and boreholes [. ZINWA Groundwater Department has been involved in groundwater development since the early 1920s as a government arm and now as ZINWA Groundwater Department since 2001 to date Borehole depths range from 40-100m but average 45-50m. Zimbabwe’s main water sources indicate that most of the country’s major dams are either in the Lowveld or Highveld where suitable dam sites are found. In this regard, we can conclude that when used to assess groundwater levels over Zimbabwe, GRACE Satellite data will still maintain a comparably reasonable accuracy. Utah State UniversityLogan, USA. Geophys Res Lett 31. All these studies show a good fit between GRACEderived groundwater fluctuations and in situ borehole records, with discrepancies between the two data sets varying from 2.1-3.5cm [24,30-34]. smaller region (~200,000 km2) than previous efforts, and it is the first Great Zimbabwe University, Masvingo, Zimbabwe. likely to continue. In Zimbabwe, The research was aimed at assessing the accuracy of indigenous knowledge data on groundwater fluctuations when compared to scientific measurements in order to ascertain if it can be used for practical groundwater management.
