How Water Footprint Assessment can be applied at different scales, from local to global, and from different perspectives, such as environmental, social, and economic. It can help to identify the hotspots and gaps in water use efficiency and sustainability, compare the water footprint with the water availability and allocation, value the water-related ecosystem services and benefits, and analyse the trade-offs and synergies between water use and wetland conservation. Water Footprint Assessment is based on the Water Footprint Assessment Manual and uses the Water Footprint Assessment Tool and the WaterStat database as sources of data and calculation in the upper Awash River basin. show it in the table form
