Subject: SLOPE STABALIZATION:

Sir,

INTRODUCTION: I represent a Bioenvironmental Approach to Sustainable Development and amheading a small, yet effective R&D NGO (Registered) that is operating in the field of SustainableDevelopment for the last 20 years. We have made remarkable breakthroughs in the fields of Agri/Horticulture Yields Enhancement; Liquid & Solid Waste Management; Low-Cost EnvironmentProtected/ Earth Quake Housing; Alternate Energy Water Pumping and Soil Conservation.

BACKGROUND: The hallmark of management is to perceive threats and take timely measures toavert them. In this regard, I wish to bring to your attention a matter of deep concern. It has beenobserved that in some areas of Muzaffarabad District, Mountain sides, denuded of Forest cover, have

suffered from SLOPE DESTABALIZATION!

During discussions with relevant Forest and MilitaryAuthorities it was discovered that a step called GREEN STABALIZATION has been taken toovercome expected further land slides that would have harmful affects upon the strategic road linkingGarhi Habibullah and Muzaffarabad. As I have not had an opportunity to survey the entire Earth Quakeaffected Area, I am not in a position to say whether similar destabilization has occurred elsewhere.

It is my firm belief that denuded slopes were the worst hit localities during the tragic quake and hadresulted in wiping out entire villages unfortunate enough to have been located below such slopes. In



case there are any populated areas below similarly affected slopes they too will be in danger of further landslides.

3. PROBLEM STATEMENT: The advent of the monsoon rains will prove to be disastrous for suchdestabilized slopes as Green Stabilization, while a fine concept has to take into consideration the longlead time required for Trees to establish themselves before they can successfully exercise their inbuilt

ability to hold the soil in place. Secondly, trees are planted under wet conditions, either during or after rains. Due to this factor the trees roots spread in a more lateral than horizontal manner. It is only at theadvent of dry conditions that rooting hormones are produced within the system to signal therequirement of deep penetration requirement of the roots in order to tap additional sources of moisture.This results in further time lag in establishing a deep root system.

These two facts when taken together have led me to the conclusion that there is a dire need for immediate measures to mitigate the foreseen problem.

4. SOLUTIONS: Scientific advances and our own on-ground trials have proven solutions that will prove to be effective in this regard. There are three recommendations for maximization of impact and

ensuring a complete solution to a perceived threat.

Polyacrylamide (PAM):Rooting & Fruiting Hormones (Natural Extract from Seaweed).Hydroseeding.

4.1 Polyacrylamide (PAM): Polyacrylamide is a new generation of chemicals introducedcommercially in the United States only in the last eleven years. The organic components of polyacrylamide were developed to chemically control erosive forces at the molecular level by holdingsoils in place and ionically bonding them together to increase the particle size. This results is increasedwater infiltration through the particle spaces and decreased erodibility of the soil particles.

PAM seeks out and binds to the broken edges of soil particles, which carry a negative charge. Byincreasing the cohesiveness of soil particles on the soil surface of a field, PAM makes soil moreresistant to the highly erosive shear forces exerted by water flowing over it. It takes very little PAM todramatically cut erosion and increase infiltration. Just 10 parts per million (ppm) added to theadvancing stream can reduce erosion by 70-99%. If there is a significant amount of sediment suspendedin the water supply, PAM will cause it to flocculate and settle out almost immediately.

The Technology Advancement Unit of the Division of Transportation Infrastructure Development,

Bureau of Highway Construction, conducts and manages the highway technology advancement program of the Wisconsin Department of Transportation. The Federal Highway Administration

provides financial and technical assistance for these activities, including review and approval of

publications.

“The performance of polyacrylamide in controlling erosion is based on the fact that it is a flocculant. Itforms ionic bonds of smaller soil particles together to make larger particles. This makes the soil moreresistant to the erosive forces of dispersion and shear. Further, the polyacrylamide enhances theintrusion of water into the soil, resulting in increased soil moisture to promote seed germination, lower runoff, and less soil detachment from erosion. Comparison of the polyacrylamide (PAM) with other erosion control products that are currently used by Wisconsin Department of Transportation (WisDOT)shows that this product is effective in controlling erosion. In addition, it is relatively inexpensive whencompared to erosion mat, very easily applied, is not affected by weather conditions, and when appliedfollowing the manufacture’s recommendations is environmentally safe.”

The above extract warrants immediate trials of the product in order to ensure that further damage is notdone to an already fractured landscape.

4.2 Rooting & Fruiting Hormones Seed Pre-Treatment:

GIBBERELLINS: Gibberellins cause enlargement of cell walls, particularly internode cells and somefruit cells. They cause breaking of dormancy, move freely in the plant and are produced in the roots andnew leaves.

CYTOKININS: Cytokinins are produced in the root tips and are carried upwards in the xylem tissue.They loose concentration as they move towards the leaves. Cytokinins affect cell division.

Hormones are produced in some organs and move to other organs to change their characteristics. For instance, in wheat early growth is dominated by Gibberellins, the middle stage by Cytokinins and thelater stages by Auxins.

HORMONE INTERACTION:

Root Initiation: High Cytokinin/ Auxin rates develop shoot growth. It reduces the Auxin+ IAA effect.The above ratios inhibit shoot growth of roots towards the tip. When Cytokinins are lower back fromthe root tip, branch roots will grow. When Auxin rates get really high, adventitious roots will appear from the stem.

The hormone balance of the plant is responsible for dictating its response to environment factors. Thisis of prime importance and the major factor for maximum economic yield if response is adequate.Good nutrition is essential for the health of the plant but will fail to provide the desired results in case a plant is unable to use this nutrition. The size, shape and yield of a plant depend upon hormone balance.Fertilizer nutrients do affect this balance but the major factor is the climate. With changes in climatethe hormone balance of the plant is altered. This is more in some varieties of plants and less in others.This is dictated by the genetics of that particular plant. It is possible to change the Genetic Expression

of a plant so that it can quickly adjust to climate change. Thus it is not essential to change the basicGenetics of a plant, which is quite an expensive proposition. By modifying the genetic expression of a plant we can weather proof it and ensure that climate change has less impact. Since the last many years,



we in Pakistan are facing the problem of vagaries in weather that is causing a serious drop in yields.Thus, it is important to introduce this alteration of genetic expression.

If the soil remains dry after planting, the root will grow downwards; if the soil remains wet it will causethe roots to grow sideways. The genetic expression of root growth is determined within the first 15

days after germination. Its genetic expression does not change thereafter. Since we plant in wet

conditions, we ensure sideways development of the root system. In case of root development in theupper area of the soil, the plant will be less drought resistant and easily uprooted. Deep penetration willmake the plant drought resistant and well anchored. It is possible to treat seed with hormones and makeit “think” that it is growing in dry soil, no matter if the soil is actually wet.

Hormones are naturally occurring elements and compounds. Thus, the use of these elements andcompounds are environmentally safe and highly desirable. It is important to note that hormone use in plants is nowise similar to indiscriminate hormones use in Poultry Production. The hormones suggestedfor use with plants are only those that would be normally produced by the plant itself if it were healthyor were to receive a balanced “Diet”. These hormone Products are registered with the EPA of the USAand natural extracts from Seaweed.

Method employed is to soak seed for a few minutes in the Product (Dosing rate is merely 2 mL per Kgseed. Seed is then allowed to dry and used for planting.

4.3 Hydroseeding: (or hydro-mulching, hydraulic mulch seeding, hydraseeding) is a planting processwhich utilizes a slurry of seed and mulch. The slurry is transported in a tank, either truck or trailer mounted and sprayed over prepared ground in a uniform layer; helicopters may be used in cases wherelarger areas must be covered. Hydroseeding is an alternative to the traditional process of broadcastingor sowing dry seed. It promotes quick germination and inhibits soil erosion.

The mulch in the hydroseed mixture helps maintain the moisture level of the seed and seedlings. Theslurry often has other ingredients including fertilizer, tackifying agents, green dye, and other additives.

4. CONCLUSION: It is imperative that this proposal be given your consideration. The impact of sucha positive step is bound to generate goodwill and earn the gratitude of a bewildered Public in theaftermath of the tragedy that that struck them. The yeoman spirit that your Organization has faced,despite great difficulties, in providing succour to the populace will long be remembered. I urge you toadd yet another Golden Chapter to the list of your accomplishments.

We have a small quantity of PAM and Seed Treatment Materials available for demonstration withenablement. It is further submitted that a sum of $100,000.00 with 50% advance would enable us to procure all materials required for Hydro Mulch Seeding within a period of 15 Days. At a rate of Rs.10.00 per square foot we would be able to stabilize slopes that are accessible by road of 6,00,000square feet or 20 sites of 300 feet x 100 feet within the Monsoon period. This would include grass seedfor rapid establishment and tree seeds as per area.

Looking forward to a quick and positive response, I wish to remain, Sir,

Yours Sincerely
