The Blue Alternative
and Permeable Hardscapes
By: Stacey Findlater
& Cesare Scarpone
By 2025 there will be 3 Billion people
living in waterless regions of the world
- UN
climatic extremes flooding long droughts forest fires
drop 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 following
Issues:
1. Creating and regenerating
groundwater supply resources
2. Flood and drought prevention
3. Restoration of the natural
production potential and
biodiversity of an area
4. To mitigate risk of natural disasters
and rising ocean levels
Land Covered With Vegetation
1- absorbs the energy of raindrops
2- slows down water
3- supports macro-organisms
The Blue Alternative Water Management Policy
- In areas with available water resources
Revitalization of the existing
landscape
• 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
-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
No trees For Dams
The Blue Alternative in a Dry Area Requires:
• Availability of a surplus
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 following
Issues:
1. Creating and regenerating groundwater resources
2. Improve water quality
3. Flood and drought prevention
4. Production Potential and Biodiversity
5. 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
