The Development Account project on Improved Water Security in Arab States aims to improve water security by strengthening the capacities of ESCWA member States for the sustainable management of groundwater resources, including through transboundary cooperation under climate change. The project will build on established experience and knowledge products on climate change and integrated water resources management to assist ESCWA member States achieve water security and SDG 6 targets. The project will draw upon innovations in water technologies that can be used for monitoring, managing and reporting on scarce water resources, geospatial analysis and remote sensing tools, and the development of interactive and accessible digital knowledge platform that can facilitate transboundary dialogue, increased capacity to cope with climate change impacts on groundwater availability, and improve water security in Arab States. This would be demonstrated by target countries implementing the following three actions: the assessment of climate change impacts on transboundary groundwater resources in at least 3 countries; the use of at least one disruptive technology for the management of groundwater resources by 3 Member States; and engagement of Member States in the development of the regional digital groundwater platform.
