Dew Water

Alternative new technologies are urgently needed to overcome the rapidly increasing global water scarcity. Atmospheric dew water is a potential source of potable water, as the earth’s atmosphere contains billions of tons of fresh water (98% in a vapor state). The atmospheric water generator (AWG) converts water vapor into liquid water and is a promising solution for water scarcity. We provide the first comprehensive analysis of the chemical profiles of water produced for several months by an AWG in the city of Tel Aviv, Israel. Metals, inorganic ions, volatile organic compounds (VOCs), and semi-VOCs were analyzed in the dew water. The main elements found were ammonium, calcium, sulfate, and nitrate. Location of the sampling site in an urban residential area, between major traffic routes, likely affected the chemical composition of the produced dew water. Nevertheless, the produced water nearly always (day and night in different seasons) met the WHO and Israeli drinking water standards. Thus, even in a highly developed urban environment, the AWG offers an excellent alternative source of safe drinking water throughout the year.

Perceived Reasons

People are directly and indirectly exposed to changing weather patterns through changes in the quality of water, air, and food changes in ecosystems, agriculture, industry, human settlements and the economy. Hence, this study explored local perceived reasons for safe drinking water scarcity and under such circumstances the coping responses in their region. This is a descriptive study based on qualitative methods. Male and female informants (30 + years of age) were purposively identified and data for the study were collected in three ways, through observation and informal discussion, in-depth interviews (n = 18), and three focus group discussions in a coastal village of Bangladesh. Climate change consequences include damaged trees and increased salinity intrusion, leading to a scarcity of safe drinking water. To cope with such scarcity of water, small scale road side mangrove tree planting was found to protect fresh water from salt water. In addition, cost effective rainwater preservation in the community during the rainy season was taken as mitigation of the scarcity of safe drinking water. Considering the geographical and socio-economic context of any specific region, cost effective and environment friendly local adaptive measures can reduce or mitigate the impact of climate change on water resources.

Cultural Assessment

While lack of access to consistent safe drinking water is estimated to affect nearly 2 billion people worldwide, many of the efforts to solve this crisis have proven to be unsustainable. This paper discusses some of the reasons for these challenges and suggests interdisciplinary practices that could be integrated from the very beginning of a water intervention to achieve long-term success. Of key importance for sustainable water implementation is an enabling environment that incorporates aspects such as funding, potential for market development, and supportive governance. While this enabling environment is acknowledged, the focus of this work is on the integration of three key areas: (i) social and cultural assessment of behavior and preferences; (ii) market-based implementation approaches that draw on this knowledge; and (iii) technology development for these markets.
