“Climate change is expected to hit developing countries the hardest. Its effects—higher temperatures, changes in precipitation patterns, rising sea levels, and more frequent weather-related disasters—pose risks for agriculture, food, and water supplies” (World Bank, 2012, http://climatechange.worldbank.org/climatechange/
"Despite projected increases in demand for water, there are still nearly one billion people without such access, and this number is growing in cities. Agriculture accounts for 70 percent of all water use, with countries increasingly tapping underground water resources that show the extraction has tripled in the last 50 years. With a corresponding 70 percent increase in the demand for food by 2050 due to population increases, the demand will lead to a 19 percent increase in the demand for agricultural water use." (The United Nations World Water Development Report, 2012, http://www.unesco.org/new/en/natural-sciences/environment/water/wwap/wwdr/
With all the increased demand, new initiatives are needed worldwide to better plan and manage water use, with technologies and investments applied to better operations. The “Save the Rain” app leverages the latest web based technologies to deliver an easy to use rainwater collection calculator. At the same time, "Save the Rain" raises the level awareness with regards to the impacts saving rainfall can make.
The "Save the Rain" app is designed with ease of use and simplicity in mind. Following a three step process, rainfall savings can be determined for any location in the world. The third step includes a summary showing the potential amounts of food that can be grown using the saved rain.
