Water for Sustainable Development Tool GreenCape, Western Cape Government, WRC This tool analyses how water constraints may impact on the economic prospects of municipalities within the Berg River Water Management Area. The interactive maps allow users to better understand the future of water in the economy in the Berg River Water Management Area over current, 2025, and 2040 water use projections. The tool contains interactive maps of the Berg River Water Management Area that allows users to determine the Irrigated Agriculture Water Requirements (An estimation of current and future irrigation requirements using bottom-up calculations based on local climatic conditions - climate change incorporated for future requirements-, crop types and irrigation efficiencies), the Groundwater Availability (An indication of groundwater availability that could be used to increase local water supply), the Economic and Employment Cost of Water Constraints (An economic vulnerability assessment of a municipality due to expected future water constraints), the Economic and Employment Value of Water (The value that water has in supporting municipal economies and employment), the Total Water Requirements Per Municipality, and the Urban Water Requirements.
Water Administration System (WAS) Strategic Water Partners Network South Africa The WAS is an integrated information management system for irrigation schemes that deliver water on demand through canal networks and rivers. WAS is used for water distribution management, debit accounts management and for the calculation of canal and dam operating procedures for a given downstream demand.
Mapping drought patterns and impacts: A global perspective International Water Management Institute This tool indicates global patterns and drought impacts mapping several drought-related characteristics at country level or regular grid scales. The tool covers various aspects of droughts, from global distribution of meteorological and hydrological drought risks, to social vulnerability and indices related to water infrastructure. This tool can indicate regions of agricultural water crowding and other drought-related data patterns.
Irrigated area mapping: Asia and Africa International Water Management Institute This tool maps the irrigated and rainfed areas of Asia and Africa using freely available remotely sensed data. The legend indicates areas of irrigated crop, rainfed crop, and water managed non-irrigated crop regions. This product updates the previous estimates of irrigated areas by using the MODIS satellite data. The usage of relatively higher resolution images and classification methods based on the seasonal profile of vegetation, significantly improves the results.

GIS Water Risk Assessment Tool        Blue North Sustainability The GIS Water Assessment Tool provides a better understanding of the potential water risks faced by South African fruit farmers within their supply chain. The GIS tool reports on a set of publically-available water and water-related parameters, where the information is displayed as user-friendly interactive “layers” on a map. A user can draw up an overall ‘water risk rating’ for each farm. Users can visually interrogate and strategically address unique water risks and opportunities and it can be used by farmers and their supply chain partners to collaborate and reduce potential water-related risks in the supply chain.
FAO Water Productivity Open-access portal (WaPOR) FAO The FAO Water Productivity Open-access portal (WaPOR) uses remote sensing technologies to monitor and report on agricultural water productivity, efficiency and measured evapotranspiration rates over Africa and the near East to help farmers achieve reliable agricultural yields and optimise farming irrigation systems. The tool performs a fine-grained analysis of water used through farming systems, generating empirical evidence about how it can be most productively used. WaPOR sifts through satellite data and uses Google Earth computing capabilities to generate maps that indicate biomass and yield production per cubic meter of water consumed. The maps can be rendered at resolutions from 30 to 250 meters, and are updated every one to ten days. The map contains the following filters: Gross Biomass Water Productivity; Net Biomass Water Productivity; Actual Evapotranspiration; Above Ground Biomass Production; Transpiration; Net Primary Production; Precipitation.
Water Auditing for Inkomati Usuthu Catchment Management Agency (IUCMA) HydroNET The Water Auditing Control Room provides water managers like IUCMA with a monitoring tool that greatly enhances the effectiveness of the agency. The dashboards shows the historical and current water use through irrigation by farmers based on satellite data from eLEAF. The water use is compared with water allocations to identify the farms with excessive water use.
MyCaneSim On-Farm Irrigation Scheduling South African Sugarcane Research Institute (SASRI) This tool calculates the water balance and crop growth of sugarcane crops. The system consists of a sugarcane simulation model, an online weather database and a communication network which automatically provides farmers with near real-time field-specific irrigation advice and yield estimates using cell phone text messages (SMS).
The Water Data Portal: River Basin Datasets International Water Management Institute The Water Data Portal: River Basin Datasets contains information and downloadable vector maps on 2 basins within South Africa; The Limpopo and Olifants Basins. This tool can be used to model basin river stream flows and drainage in the Limpopo and Olifants basins.
The Water Data Portal: Hydrology & Water Resources Model Inventory International Water Management Institute The Water Data Portal: Hydrology & Water Resources Model Inventory contains a Water Resource Simulation model developed to showcase simulated scenarios of water development in the Olifants catchment. This tool can be used to project scenarios in the Olifants catchment such as water demand, water resources development, irrigation, rural demand, industrial demand, urban demand and more.

The tool also provides the following: Country water profiles with detailed information on national government policies, resources, and governance measures. Identifies hidden water risks in operation, supply chain and investments. Evaluates impacts of other factors on water risk. Calculates financial values associated with water risk. Combines water risk assessment details with financial impacts to show how water risk events can affect financial statements (from revenue loss due to droughts to depreciation of assets due to floods).
