When community members and water managers work together large strides towards water security and independence can be achieved. While the future of the planet is urban the greatest inequities are rural this poses unique challenges in achieving – water security. Water Quality, but not Quantity? The team of researchers also developed a cooperative game theory framework that can be used to analyse water management policies that address scarcity and drought (Kahil et al., 2016). Countries across the world are facing the problem of water scarcity. This is in line with the integrated water resources management (IWRM) approach, which calls for collaboration among all stakeholders in water management. UN–Water has identified coping with water scarcity as part of the strategic issues and priorities requiring joint action.

Part of Water scarcity affects more than 40% of the global population. Scarcity has many drivers, starting with: freshwater only accounting for 3 percent of all water on earth. In fact, the time period over which precipitation deficit accumulates is a determing factor for the occurrence of drought. The results will help businesses develop strategies to mitigate water scarcity risk and contribute to global water conservation. Local water scarcity risk (LWSR, meaning potential economic output losses in water-using sectors due to physical water scarcity) can be transmitted to downstream economies through the globalized supply chains. But interventions tend to … Integrated Water Resource Management (IWRM) is becoming recognised as the only sustainable solution to water scarcity. In zones where there is no available drinking water, the main risk is dehydration obviously. There simply isn't enough.

Climate engineering or commonly geoengineering, is the deliberate and large-scale intervention in the Earth's climate system to counteract climate change. The challenge of implementing engineering solutions is identifying the appropriate technology and overcoming region-specific political, social, and economic hurdles. The CO 2 required for these machines is recycled from other industrial uses, so not only does it contribute to solving the water shortage crisis, but also helps with climate change. Water sustainability is a global concern. But interventions tend to solve water scarcity problems at a local level, while aggravating water scarcity downstream. At present, there are no existing water quantity standards, but there are water quality standards. In cities, 82% of people have a basic supply.
