The national water award in 2008 indiaBreakdown of the water cycle causes a rise in climatic extremes, flooding, longer droughts, forest fires, drop in groundwater reserves, decrease in soil fertility and biodiversity.
Improve water qualityThe blue alternative solution can be used in countries with repeated incidence of atural disasters, lack of water resourses, problems growing food, in dry semi arid regions, or completely dry countries. Strengthening of the atmospheric water vapour layer for protection against intense solar radiation
1- absorbs the energy of raindrops and prevents packing of the soil that inhibits infiltration 2- slows down the water giving it more time to absorb into the ground water3- supports organisms that aerate the soil, which allows for easier infiltrationIn areas with available water resources- By creating a network of small dams and water catchments to slow the flow of water.In dry areas with seasonal rains- By creating small mud dams to slow monsoonal rains, and storing excess water in percolation tanks.
Sri lankan king Parakramabahu the Great—"Not even a single raindrop should be allowed to flow into the sea without it first having been used for the benefit of the people..." —is the best summing up of the new water paradigm, a statement which, in the coming decades, should become a slogan for mankind calling for the preservation of civilization.revitalization of the ability of the existing landscape to store and absorb water construction of many small catchments the creation of wetland and ponds to slow runoffto increase the volume of water in natural ecosystems supportive agricultural and forest management practicesincreases the volume of water in natural

Blue Alternative and Permeable Hardscapes
The Blue Alternativeand Permeable Hardscapes By: Stacey Findlater & Cesare Scarpone
By 2025 there will be 3 Billion peopleliving in waterless regions of the world- UN
climatic extremes flooding long droughts forest firesdrop in groundwater reserves decrease in soil fertility and biodiversity
Where did the water go?• Sea levels are currently rising which impacts human populations living on islands or in costal regions• Satellite measured average rise of 3.3mm per year from 1993 to 2009
The Blue Alternative Solution can be used for the followingIssues:1. Creating and regenerating groundwater supply resources2. Flood and drought prevention3. Restoration of the natural production potential and biodiversity of an area4. To mitigate risk of natural disasters and rising ocean levels
Land Covered With Vegetation1- absorbs the energy of raindrops 2- slows down water3- supports macro-organisms
The Blue Alternative Water Management Policy - In areas with available water resourcesRevitalization of the existinglandscape• Construction of many small water catchments• The creation of wetlands and ponds to slow runoff• Supportive agricultural and forest management practices
The Blue Alternative Solution No trees For Dams-In dry areas with seasonal rains • Small mud dams slow monsoonal rains • Excess water is stored in basins or percolation tanks • To replenish local ground water aquifers and restore productivity • At the lowest possible cost
The Blue Alternative in a Dry Area Requires: Jan - Sept• Availability of a surplus Oct- Dec 67% monsoon rain water• A suitable hydrogeological environment and locations for building water catchments
Water Retention in Dry Climates• Check dams• Contour Bunds• Recharge trenches• Percolation tanks• Planting trees
Artificial Recharge Techniques• Enhance the sustainable yield in areas• Conservation and storage of excess water for the future seasons• Improve the quality of existing groundwater• Refill aquifers
The Blue Alternative Solution can be used for the followingIssues:1. Creating and regenerating groundwater resources2. Improve water quality3. Flood and drought prevention4. Production Potential and Biodiversity5. Natural disasters, Rising ocean levels and Iceberg melting.6. Atmospheric water vapour layer
• the conservation of rainwater on land and the selling of only the natural surplus of water in a region is essential for ensuring the environmental security , global stability and the sustenance of economic growth. Fulfilling these interests should be of interest to each individual and each community
