This inventory of tools and models on early warning and flood forecasting was developed under the Associated Programme on Flood Management, a WMO-GWP programme. The primary purpose of this inventory is to provide information about interoperable models and platforms whose use is most likely to bring long-term success in flood forecasting and early warning systems. The inventory is designed to help scientists and engineers in National Hydrological Services who are trying to select appropriate models and platforms for their needs.

The FAO Drought portal is a global knowledge-sharing platform to support countries and stakeholders in enhancing the resilience of agriculture and improving food security. The Drought portal builds on the Integrated Drought Management (IDM) approach, to foster the transition from crisis-led and reactive responses to risk-based and proactive measures. The Drought portal provides resources towards the following objectives:

The SDS Toolbox provides tools, guidance and information which can be used to identify the sources of sand and dust storms, develop and implement management policy, plans and strategies, assess risks and vulnerabilities to SDS, understand how to observe, monitor, forecast and provide warnings of SDS and develop and implement ways to mitigate the impacts of sand and dust storms. There are five modules:

A broad range of Earth Observation tools and models exist to help with global flood forecasting, monitoring and impact assessment, each with unique inputs and capabilities. This variety can make it challenging for potential users (i.e.humanitarian and government agencies) to choose the optimal tool to prepare for, mitigate, and manage responses to specific flood events without a clear way to discern between tools or understand the options available.

The SSWM Toolbox is the most extensive collection of knowledge about sustainable sanitation and water management. It compiles thousands of "best of" instruments – be they technologies, methodologies, behavioural change approaches, or planning tools – designed to optimise sanitation and water management intervention at the local level. These instruments have been curated in an accessible and exhaustive manner.

The Drought Toolbox provides tools, case studies, and other resources in order to support the design of the National Drought Policy Plan with the aim of boosting the resilience of people and ecosystems to drought. The drought toolbox collates a large number of tools organized into three modules: PILLAR 1: Monitoring and early warning; PILLAR 2: Vulnerability and risk assessment; PILLAR 3: Risk mitigation measures

The Groundwater Catalogue is a Wikipedia-like application designed to provide comprehensive information on groundwater management tools, measures, and instruments, including supply and demand, groundwater protection, and stakeholder involvement. On the basis of factsheets, case studies, and references, the catalogue will allow policymakers and decision-makers to explore appropriate solutions for complex groundwater issues.
