1) EAST BALI WATERSHED MANAGEMENT PROJECT USING BAMBOO  

Summary

Watershed Area Rehabilitation in Karangasem, East Bali.

The Balinese landscape consists of hilly terrain dominated by ridges which extend from east to west and connect a number of volcanoes. Five volcanoes have an elevation of more than 2,000 metres; the ridges of this mountainous area form the boundaries for Bali Island’s main watersheds. Bali has an average annual precipitation of 2,150 mm with an average maximum annual rainfall of 2,700 mm. The southern part of Bali consists of gently sloping valleys tends to have quite good groundwater supplies while the northern part consisting of more steep valleys sloping towards the sea has less groundwater supplies.
Various types of water resources (precipitation, surface water and groundwater) in Bali are commonly used for rice-field irrigation, non-rice field irrigation, domestic, industry and tourism purposes. Research conducted in 1992, shows only 21% respondents used PDAM (state-owned fresh water company) water while 27.5% used bored wells and 73% used shallow wells. Generally, based on the recent study, inhabitants who relied upon groundwater for domestic purposes used an average of 60 to 120 liters/person/day in both urban and rural areas.
In general, the balance between water need and availability in Bali based on the 1995 research, has shown – 1,507 million m3/year and it is projected that in the year of 2015 Bali will suffer from app. 7.5 million m3 water deficit.
Karangasem Regency in general, has already suffered from water shortage at 33.7 million m3 in 2002 for non-rice field irrigation and domestic needs.
Based on above statistics, the Environmental Bamboo Foundation is piloting a project to rehabilitate the critical watershed areas especially in Eastern Bali. Our technical assessments resulted in the choice of Bukit Paon Hills (886 m), Bhuana Giri village of Bebandem District to be the first pilot project covering about 50 hectares of degraded protected forest area. EBF is planning to plant at least 15,000 bamboo seedlings (mostly black bamboo/Gigantochloa atroviolacea)to cover the area multi-cropping with the existing stands (mostly pine trees).
The project has three main focuses; reforestation, watershed rehabilitation, and socio-religious aspect providing most used material for Balinese regular temple ceremonies: bamboo poles. EBF hopes that in the next five years there will be new springs coming up somewhere around the nearby villages as well as emerging small enterprises on bamboo handicraft as an alternative income generation drive for local communities.

EAST TIMOR RECONSTRUCTION AND REDEVELOPMENT PROJECT   (back to top)

The Environmental Bamboo Foundation, International Bamboo Foundation and Designers For the Environment currently has a bamboo plantation project under way in East Timor. As most of you may know, the East Timorese were treated in the same way as the Kosovars and nearly everything was destroyed by the Indonesian militia before independence was declared.

In 1999, Linda Garland, president of the EBF and IBF and Jane Hawkins in Bali, went to East Timor to bring dyed thread to the women there so that they could begin to revitalize their weaving industry. The Ikat weaving and furniture industries, once thriving were destroyed along with most homes and businesses, but these are now being salvaged through the efforts of the Designers for the Environment. Linda Garland, one of the worlds top 50 designers, began marketing the cloth incorporating it into high end cushions to bring much needed income to the women of East Timor, rebuilding basic infrastructure and their economy. This is a non-profit enterprise and fundraising continues to be held in America to support several projects, the purchase of tools, an orphanage, a bamboo restaurant, plantation, nursery and a school are currently being planned.

Nearly every family is missing a father or mother and the present situation is very troubling, in particular the situation regarding the street children orphaned during the coup. There is a great need for very basic infrastructure, trucks, buildings, plumbing, communications, electricity etc. The International Bamboo Foundation has been collecting and sending funds to East Timor for these necessities this last year and welcomes any support from the public. Click below to make a tax deductible contribution to the IBF which will support our efforts there. Thank you for helping the Timorese people and the environment! All contributions over $300 are tax deductible which will be acknowledged by a receipt and a "Report to Donors".
Recently begun, are GIS aerial surveys of the bamboo resources available to develop agroforestry information for the production of construction grade bamboo.  This project has created jobs for the local women and will eventually lead to the development of a bamboo industries.. Our team organizer, Hector Hill of Australia reported last November :

"East Timor is only in the earliest stages of recovery......the people who are making the furniture in the mountains, are still now after 12 months since the destruction building their homes, re-establishing their communities and subsistence food production. We are providing as many as we can with vegetable seeds now as the rains break to help them along, it is not much but it's enough........treating rattan is something they would love to do, and for the moment, we seem to be lucky, I have seen borers in only one set, and they have been exposed to borers for a while. The designs and quality are very basic, but then there is so little furniture in East Timor after 85,000 houses were burned amongst everything else.....phone, power, water systems destroyed, that where we have started now is enough........as much information as you or others can send us, particularly relevant for people with little or no resources will be most welcome........maybe INBAR could help fund our work?? I know its not quite along their lines, being a post destruction recovery situation, but what better time to start, when there is so little else to work with in the way of local resources.

Things are proceeding excellently. OMT is keen to do the bamboo survey, and we have worked on the logistics. A group from the University of Lisboa......who are working for the people and not for UNTAET and who have the best GIS system and complete 3-D mapping facilities have offered to engage the women to collect data for them which will in turn be returned with technical assistance to help with a bottom up based approach to national planning in all sectors..... for around 70.000.000 Rp we can do the whole country's bamboo resources, and mobilize the women of east timor in a whole range of other activities at the same time. "

DESERTIFICATION: It's Not Just the Sahara Anymore...
"Anthropogenic effects" - Human  made conditions that can change weather patterns, the greenhouse effect may be such an effect as CO2 gases from cars and other sources may be trapping heat and energy in the atmosphere causing general increases and more extreme weather. The pattern of flash floods, rapid runoff, and rapid return to drought is characteristic of another anthropogenic trend: desertification. Desertification is worldwide and such a serious problem that the UN has drafted a special convention to combat it.
Both rainforests and deserts are self perpetuating. Forests soak up rainfall like a sponge, slowing its downhill flow and returning much of the water to the air as humidity, which condenses to fall again as rain. Forest foliage also converts the  energy of sunlight into growth, shading the soil beneath and dropping  the overall temperature. When forests are removed, temperatures rise and the soil bakes hard. Rain falls less often, and when it does, it runs off, especially on sloping ground. Topsoil erodes, further decreasing the land's ability to recover and to hold moisture.

"Desertification is caused by climate variability and human activities", reads one UN fact sheet. "In the past, dry lands recovered easily following long droughts and dry periods. Under modern conditions however, they tend to lose their biological and economic productivity quickly unless they are sustainably managed. Today dry lands on every continent are being degraded by over cultivation, over grazing, deforestation and poor irrigation practices. Such overexploitation is generally caused by economic and social pressure, ignorance, war and drought".

Efforts have been under way tin recent years to replant  degraded lands with eucalyptus. But some environmentalists charge that eucalyptus is a notoriously thirsty tree that may actually contribute to desertification. In a policy paper on eucalyptus plantations in Brazil, for instance The Bioenergy Information Network noted that  "One criticism of eucalyptus plantations is tat they can promote a change in the local climate. This is because of the very high evapo-transpiration rate of eucalyptus. which drains water from the soil leading to a lower water table. This high evapo-transpiration rate is claimed to adversely affect local rainfall levels resulting in possible desertification of the area".

Executive Summary  

With Excerpts from Bamboo Preservation Compendium – Walter Liese and Satish Kumar.
“The uses of bamboo are almost limitless.  Bamboo culms are used in products that range from handicrafts and utility items, to industrial products and structural components of engineered bridges and buildings. It is because of these uses that bamboo offers tremendous livelihood potential to rural communities and business opportunities to industry.”

“One of the main obstacles to even more widespread use of bamboo is its susceptibility to degradation. A biological material like wood, bamboo is vulnerable to factors like fire and weathering and to attack by pests and microbes.  This vulnerability reduces the lifespan of the bamboo product [to 6 months -2 years in Indonesia].  Like with wood it is possible to safeguard bamboo against deterioration by preserving and protecting it, by adopting certain practices during [harvest], storage, processing and use.”  Effective treatment and handling of bamboo will not only increase the life of the product, but the value of bamboo as well, currently tremendously undervalued as a commodity.

The bamboo preservation technique which is the focus of this program is the “Vertical Soak Diffusion” method.  This process was developed and standardized by the Environmental Bamboo Foundation, Bali.  The process involves placing freshly harvested culms against a wall and piercing the dividing diaphragms with an iron rod.  All the diaphragms are pierced except for the last one, which enables the bamboo culm to act as a container for treatment solution.  The culms are stood upright in a shallow basin which is covered with a 7 meter roof to protect the bamboo from rain and sun.  The inner space of each bamboo culm is filled to the top with a treatment solution consisting of a mixture of borax and boric acid (in a ratio of 6:5 or 3:2) commonly at a concentration of 5% or 10% depending upon end-use.  The preservative will diffuse into the inner tissue towards the outside skin and also through the ruptured diaphragm into the opened vessel system of the adjoining internodes.  In order to determine the depth of penetration, a small amount of high quality analin textile dye or its equivalent is added so that after approximately 2 weeks [varies with species] a cross section of the bamboo wall will appear reddish. The solution in the inner space has to be topped up regularly due to absorption into the tissue of the bamboo and evaporation into the atmosphere.  At the end of the treatment the remaining diaphragm near the ground is punctured with the tip of a metal pipe so that the solution drains from the culm into the sump hole of the sloped basin floor.  This solution is then recycled up to 4 times after being passed through a swimming pool filter to remove large particulate impurities. The culms are then stood at a 45-60 degree angle for two days to complete draining and begin drying before being moved to a shaded horizontal drying rack a minimal distance of 60cm above the ground.  The culms are then air dried for 2-4 weeks depending on the weather’s humidity. A detailed manual of this method was produced by EBF with assistance from MAP-Indonesia and can be downloaded from www.bamboocentral.org.

MAP-Indonesia/YARL has since developed VSD treatment facilities in Cilacap, North Sulawesi, Aceh, and Timor Leste in village settings as part of community center construction projects and livelihood alternative projects.  MAP-Indonesia also trained a village from Tembi Village in Bantul in the VSD method who subsequently treated bamboo for post earthquake housing (roofing for 150 houses plus main structural bamboos for 4 community center buildings).  This UNIDO sponsored project is the first time that VSD bamboo has been tested in a medium enterprise setting outside of the Environmental Bamboo Foundation.  This trial was important to determine actual start-up and operational costs of developing VSD treatment from scratch.
Principal Program Activities  

There were four (4) principal activities in this program; 1) Participatory planning, 2) Development of bamboo treatment facility, 3) Bamboo preservation, and 4) Preparation of a cost/benefit analysis of bamboo preservation.  There were also several supporting and evaluatory activities.

I) Participatory Planning
From the onset, this project involved bamboo artisans/showroom owners from Sendari village, village government, bamboo experts and researchers in all phases of planning and implementation. Participatory planning sessions were held in Sendari and at our office at UGM from October 15 – November 15, 2006.  During planning, several changes were made from the original proposal to UNIDO; 1) construction of a permanent bamboo treatment facility which resulted in a larger overhead cost, 2) construction of a bamboo storage area and operational base.  These changes were discussed with UNIDO on Dec 17 during a site visit.  The increase in cost of infrastructure in Sendari made it impossible to build a smaller separate facility in Pakem for research and development.  R&D was therefore done on site in Sendari and also at the chemical laboratory of Yayasan Dian Desa.

II) Development of Bamboo Treatment Facility
Construction of the Vertical Soak Diffusion treatment center was completed in 5 weeks, from November 26th to December 31st 2006. Construction took place in 6 steps; 1) Preparation of building foundation and concrete pedestals, 2) construction of concrete basin, 3) bamboo treatment, 4) assembling bamboo frames, 5) raising of bamboo frames and 6) installation of electrical and plumping fittings.

The construction was to include wings for storing of incoming bamboo and drying of post-treated bamboo, but this was not built until after sale of initial treated bamboo (lack of funds). The entire construction was built with bamboo, to act as an on-site demonstration of bamboo construction.  The building was designed by local bamboo artisans from Sendari who have previous bamboo construction experience as facilitators for Mangrove Action Project in building community centers in Indonesia and Timor Leste. Bamboo used in the construction of the treatment facility was treated by boiling in a 10% solution of borax/boric acid for a period of 3 hours (because VSD treatment could not be used prior to facility construction).  This; however, proved an in-effective treatment method as bamboos were attacked post-treatment by powder-post beetles.  All infected bamboo members in the construction were subsequently treated with the insecticide Dursban which has so far proven effective at terminating pest infection.

The finished bamboo treatment area measures 13 meters x 8 meters, including an 8 meter by 6 meter treatment area and an 8 meter x 5 meter drying and storage rack. The treatment area has a capacity to treat 400 culms of Dendrocalmus asper (18-20 cm diameter) or 1000 culms of the smaller diameter bamboos such as Gigantochloa apus, G. atroviolacea or G. atter (average 10 cm diameter) each 12-day cycle.

III) Bamboo Preservation
Bamboo was treated using the Vertical Soak Diffusion method developed by Environmental Bamboo Foundation of Bali in conjunction with Walter Liese of University of Hamburg – Wood Products Laboratory.  All bamboos were treated with a solution of borax (Na2B4O7.5H20  -  14.9% boron) and boric acid in a 6:5 part ratio at a concentration of either 5% (for furniture and handicrafts) or 10% (for construction).  Culms were kept filled with solution for a period of 12 days, after which they are emptied and dried.  Leftover borate solution is re-used a maximum of 4 times, after which it is added to a horizontal bath for treatment of split bamboos.

IV) Cost Benefit Analysis
A cost/benefit analysis was performed based on start-up costs as well as treatment of the first 200 poles of four economically valuable bamboo timber species (Dendrocalamus asper, Gigantochloa apus, Gigantochloa atroviolacea and Gigantochloa atter).  Production price of these four bamboos is as follows:

A detailed cost-benefit analysis has been performed and is available as an Excel file split into six worksheets and attached as Appendix A.  This file is meant to serve as a template for similar bamboo treatment ventures (both up start and operational).  It must be remembered that the figures in this cost-benefit analysis were calculated during the research and development/start-up phase of this operation.  There are thus many inefficiencies which drove up the initial cost of treatment.  This is primarily the case when considering labor costs as processing and handling times increased significantly.  A second cost/benefit analysis will be performed in 6 months time when the operation is running at normal efficiency and this data will be used to augment start-up data for dissemination purposes.  
                                                                      

Supporting Activities  

Forming a bamboo treatment cooperative
After completion of initial research and development for preparation of the cost/benefit analysis, our findings were reported to the local bamboo artisan’s cooperative.  During this process we discussed the original concept of setting a local management team for the treatment facility.  Contrary to their initial desire, the artisans asked MAP-Indonesia to continue to manage and operate the treatment facility, expressing that they were now only interested in purchasing low-cost treated bamboo.  It was felt that operating the bamboo treatment facility would take too much time would be taken away from their craft work.  The Artisans stressed that use of treated bamboo was still very much in their financial interest, but were not willing to expand into bamboo preservation on their own.  They also stated that all qualified available local workers were already employed in the furniture making and handicraft industry.  Whether or not this is true, due to their change in attitude, MAP has formed a production unit called Sahabat Bambu comprised of local villagers and newly recruited staff.  Sahabat Bambu is currently operating the bamboo treatment facility to supply local artisans as well as a treated bamboo lumber yard for construction material.  Sahabat Bambu’s goal is to form a producer/supplier chain for sustainable, durable bamboo products.  More information on Sahabat Bambu’s activities and objectives can be made available upon request.

On-Site Demonstration Bamboo Construction
The bamboo artisan’s cooperative of Sendari and Sahabat Bambu received a donated bamboo house from CV IndoBamboo of Malang.  Ten similar houses are being constructed in Imogiri as part of earthquake recovery activities.  It was suggested to IndoBamboo to build a house on the site of the treatment facility in order to promote bamboo as a durable, sustainable construction materials.  This house will serve as an exhibition space, office and meeting area for the artisan cooperative and Sahabat Bambu.

Orders for Treated Bamboo for Post-Earthquake Reconstruction
Sahabat Bambu has already received tender from AMURT – Indonesia to supply construction materials for a nursery school in Berbah, Sleman. This project began on March 12, 2007.  Sahabat Bambu has also received orders for treated bamboo from local architects as well as the bamboo artisans’ cooperative of Sendari. These additional orders total 500 culms which have already been treated.  Profits from this initial bamboo sale were used to construct bamboo storage areas, put a floor in the donated bamboo house, and pay staff salaries.  The treated bamboo ordered by local artisans is being used for local post-earthquake house construction (not part of an aid/recovery project), and knock-down gazebos for export to England.

Research & Development
Sahabat Bambu is experimenting with different concentrations and mixes of borax and boric acid based on research from Walter Liese, the Australian Government’s Forest and Wood Products Research & Development Corporation, and CV IndoBamboo.  We are testing sample cross-sections of treated bamboo using the procedure detailed in Appendix B.  Bamboo tested has shown full boron penetration in all species of bamboo after 12 days treatment.  We will continue experimenting and testing for boron penetration in order to maximize efficiency of the treatment process in hopes of shortening treatment times for thinner walled species of bamboo.

SaBa is also experimenting with natural preservatives but this research is still nascent.  Sahabat bamboo also experimented with an-all bamboo floor design during this time period as well as carbonization of waste bamboo for charcoal and charcoal vinegar production.  A temporary charcoal kiln was donated to this project from Yayasan Bina Usaha. The bamboo charcoal will be used for fuel, water filtration and agricultural applications and is a recommended side business for utilization of non-preserved bamboo waste material.  A separate cost-benefit analysis of this charcoal operation will be prepared over the next 12 months.
   
Opportunities and Risks for Bamboo Preservation as a Small/Medium-Scale Enterprise.  

Opportunities:
Based on the cost-benefit analysis, this medium-scale enterprise has excellent prospects in terms of return on investment.  Demand for treated bamboo products, especially in the post-earthquake context is high, but also bamboo is being used more and more frequently for investment based infrastructures such as restaurants, storage units, semi-industrial production facilities, etc.  A production facility of the size developed durng this project should net  $1000 per month given continuous demand.  The return on investment averages 5.5 months.
Related to provision of labour, this bamboo production unit requires seven (7 ) full-time staff per work-day for operation and marketing/sales.  During large construction projects, we also employ five local construction workers per unit construction.
Bamboo artisans utilizing treated bamboo in their furniture products and larger handicrafts are able to sell at a 40% mark-up while their incurred cost of using treated bamboo is only an additional 10% of their total production cost.
Risks:
Availability of Borates:  During this project period, the Ministry of Industry and Medium Enterprise banned the import of Borax.  This was due to its illegal and under-regulated use in the food industry as a preservative for tofu (tahu), meatballs (bakso) and other processed foods.  Sahabat Bamboo is in the process of contacting other bamboo treatment practitioners who rely on a constant supply of borax (Environmental Bamboo Foundation, Bandung Institute of Technology, University of Gadjah Mada, Indobamboo) to petition the government to allow for supply of borax and wholesale to bamboo preservation units.  Sahabat Bambu is also requesting that PT Chemafin renew supply of Tim-bor , a pre-mixed borate preparation ideal for treatment due to higher solubility in water.

Availability of Bamboo:  This is perhaps the most serious risk to a sustainable venture in bamboo treatment.  During the first six months after the Yogyakarta earthquake the demand for bamboo for emergency and transitional shelters was unprecedented for this region.  During the first six weeks after the disaster it was not uncommon to see 1000 trucks per day of community volunteers and bamboo (whole bamboo culms, plaited bamboo walls, and bamboo roofing material) riding into Bantul.  Aid agencies were not far behind.  Data from IOM show use of 50,000 bamboo culms per week in producing 12,000 total emergency shelters during a  four month period after the disaster (totaling 600,000 culms). CHF followed close behind using 2000 culms per day over a similar period.  IOM received an second contract from the World Bank to produce 16,000 additional bamboo shelters in the second six month period after the quake.  These shelters, built with un-treated bamboo are predicted to last 2 years, after which most of the bamboo members will need to be destroyed due to insect infestation. 

Can the bamboo resource withstand such heavy harvesting pressure?  The answer is NO, or at least not without mechanisms in place for sustainable harvest.  Unfortunately neither government nor private institutions have made a genuine effort to regulate bamboo harvest.  On Dec 24, YARL was on a bamboo resource survey and purchasing trip in the area of Wonosobo, Central Java.  A verbal agreement was made to harvest 3+ year old culms of Gigantachloa apus, 500-1000 clumps of which were growing in the village.  When a YARL purchaser returned on January 14th to make a down-payment, every single available clump of bamboo in the village had been harvested, new shoots and one year old bamboo’s included.  This clear-cutting of bamboo is also unprecedented as every villager knows that once a bamboo clump is clear-cut, it is for all intents and purposes dead.  The buyer (pemborong) said that bamboo was purchased to meet an order placed by CHF.  When asked about harvesting controls, CHF stated that they order 2+ year old bamboo but admitted that there was no enforcement mechanism.  Bamboo considered obviously too young (one year old) was rejected during the first several months, but as bamboo became increasingly scarce, year old culms are being accepted. Bamboo collectors (pemborong) were able to sell even rejected bamboo as scaffolding material to construction suppliers as their trucking costs were often met by sale of bamboo to the international relief agencies.

It is not our intention “to blow the whistle” on the management practices of relief agencies, but rather to highlight the point that sustainable bamboo harvest guidelines are needed now more than ever.  Grower-buyer relationships need to be established that provide financial benefits to growers for harvesting mature bamboos only, leading to sustainable management of the resource.  Prior to the 2006 earthquake, handicraft and furniture makers from Cebongan had already noted scarcity of bamboo resources, Balinese artisans have placed orders for bamboo from Central and East Java already for a decade due to local shortages on that island. As it stands, bamboo reforestation activities will also need to be undertaken immediately to replenish this economically and environmental valuable resource. 

Quality Control of Treatment Procedure:

Borate treatment should effectively treat any fresh-cut bamboos. Nonetheless, variability in material due to starch content, dryness, presence of powder post beetles in the local vicinity, etc. may play a role in terms of effectiveness of treatment.  The simple chemical test provided as Appendix B can help practitioners check penetration of boron.  A checklist on  handling and storage of bamboo both pre- and post-treatment will also help ensure quality control.  When mixing the borate solution, it is important to add a fixed amount of high-quality analin textile dye (preferably red) in order to 1) provide a rough estimate of boron penetration and 2) differentiate between treated and untreated bamboo both on-site and in terms of allying competition that may promote sale of “pseudo-“ treated bamboo.

Method for Determining Boron  

Reagents

Solution 1. Extract 10g turmeric powder with 90 ml ethyl alcohol.  Decant or filter to obtain clear solution.

Solution 2.  Dilute 20 ml of concentrated hydrochloric acid to 100 ml with ethyl alcohol and then saturate with salicylic acid (about 13g per 100ml).

Procedure

A smooth surface shows the results of the spot test better than a rough surface.  The surface must be dry otherwise the test will not be satisfactory.

Solution 1 is applied preferably by spraying or with a dropper to the surface to be tested.  The surface being treated is then allowed a few minutes to dry.

Solution 2 is then applied in a similar manner to the areas that have been colored yellow by the application of solution 1.  The color changes should be observed carefully and will show up a few minutes after application of the second solution.  In the presence of boron, the yellow color of the turmeric solution is turned red.

After reagent application, placing bamboo in a warm oven accelerates and intensifies the color reaction to better differentiate between treated and untreated bamboo.
