Global Reservoirs and Lakes Monitor (G-REALM)

G-REALM provides time-series of water level variations for some of the world’s largest lakes and reservoirs. Currently, lakes ≥ 100km2 are included but future project phases will aim to include those in the 50-100km2 size range.


GEOGloWS ECMWF Streamflow Service

GEOGloWS helps to organize the international community engaged in the hydrologic sciences, observations, and their application to forecasting and provides a forum for government-to-government collaboration, and engagement with the academic and private sectors to achieve the delivery of actionable water information

Water Balance

The app is based on data from NASA’s Global Land Data Assimilation System (GLDAS-2.1), which uses weather observations like temperature, humidity, and rainfall to run the Noah land surface model. This model estimates how much of the rain becomes runoff, how much evaporates, and how much infiltrates into the soil. These output variables, calculated every three hours, are aggregated into monthly averages, giving us a record of the hydrologic cycle going all the way back to January 2000.

Earth Map

Earth Map is an innovative, free and open-source tool developed by the FAO. It was created to support countries, research institutes, farmers and members of the genral public with internet access to monitor their land in an easy, integrated and multi- temporal manner. It provides satellite imagery and global datasets on climate, vegetation, fires, biodiversity, geo-social and other topics. Users need no prior knowledge of remote sensing or Geographical Information Systems (GIS).



Water Use Efficiency Monitor in Central Asia (WUEMoCA) is an operational scientific web mapping tool for the regional monitoring of land and water use efficiency in the irrigated croplands of the transboundary Aral Sea Basin that is shared by Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan, and Afghanistan. Satellite data on land use, crop production and water consumption are integrated with hydrological and economic information to provide of a set indicators.


Agricultural Water Productivity

Agriculture Water Productivity Mapping for Central-Asia (AWP-CA) is the Google Earth Engine supported on-the fly web mapping tool by harvesting open access data and also calculating derived indices and products for the given period. Tool display data and relative production variability across the region or zoom to specific country. The framework of AWP can be a convenient tool to evaluate the performance production systems at spatial and temporal scales.


Sustainable Land Management Tajikistan

Sustainable Land Management Tajikistan (SLMTJ) is a knowledge platform on Sustainable Land Management in Tajikistan. The SLMTJ Knowledge Platform will provide access to the knowledge materials and aims to strengthen the collection, sharing and dissemination of best practices and methodologies on SLM among different stakeholders.



World Overview of Conservation Approaches and Technologies (WOCAT) provides tools that allow specialists in sustainable land management (SLM) to identify field sand needs of action, share their knowledge in land management, search for appropriate SLM technologies, and support them in making decisions in the field and at the planning level and in upscaling identified best practices.
