DESCRIPTION

A presentation that describes the current state of water in Sri Lanka. The presentation is given in the contact of Analog Forestry design and application, and offers a solution through the management of tree dominated ecosystems for water related issues. The presentation is offered from Dr. Ranil Senanayake.

Page 2: Water (from an Analog Forestry perspective)

In Sri Lanka The mountain Forests are the water generators

Globally ForestsCycle the atmospheric water reservoir (over

28,300 GT/yr)

Photosynthetic BiomassContributing Cloud Condensation Nuclei (CCN)

( an increase in global albedo by 1-2% can diminish the warming effect of CO2 by over 50

years.)

Page 5: Water (from an Analog Forestry perspective)

The difference between live and dead clouds

Page 6: Water (from an Analog Forestry perspective)

The forests not only create rain they also maintain clear water

Page 7: Water (from an Analog Forestry perspective)

Modern land use changes there relations

Page 8: Water (from an Analog Forestry perspective)

Agrotoxins are added to the montane regions at the rate of 24 Kgs/acre/year

Page 9: Water (from an Analog Forestry perspective)

These agrotoxins coupled with industrial toxins render surface water

unusable and toxic

Page 10: Water (from an Analog Forestry perspective)

Modern land use methods erode the water quality of the nation

Page 11: Water (from an Analog Forestry perspective)

Eventually this land based pollution degrades the ocean ecosystems

Page 12: Water (from an Analog Forestry perspective)

No attention was paid to these concernes and by 2010 due to inaction Sri Lanka became the

worst polluter of the Indian Ocean

Some applicable principles

• Principle 5 Map out flow and reservoir systems

• Principle 7 Be guided by landscape needs

• Principle 9 Utilize ecological processes
