Tabel 9.1.1 Pelajaran dari Pengalaman Sebelumnya Pada Proyek-proyek Konservasi DAS Wonogiri

- Well integrated & coordinated physical and vegetative or civil and agricultural measures are-

-

-

- Not blue print approaches, but area specific & flexible prescriptions by watershed conditions are-

-

- Crop Selection & Cropping Pattern- Need of crops tolerant to dry climate & with adequate economic value- Introduction of area specific superior crops/commodity andalan for dry land- Further adaptation of multiple cropping system with legumes should be aimed for improvement of- Development of commodities suitable for conservation purposes is to be envisaged.- Selection of agricultural commodities should be based on market potential followed by technical &- One alternative is to combine perennial crops with seasonal crops in home compound & dry farm

- Project failed because of top-down management & use of inflexible prescriptions poorly adapted to loc-

-

-

-

- Monitoring of performances of the programs implemented seldom practiced in the past. -

-

- Legal or official procedures will be necessary for controlling cropping pattern in dry farm land.

-

--- Multi-stakeholders dialog at district & watershed levels are to be maintained.-

-

-

1/: Lessons learned was extracted based on the review on the following reports & interview with the agencies concerne-

-

As farmers are becoming more interested in income earned in non-agricultural activities, they areincreasingly reluctant to invest in their own farm especially when it concerns maintenance of their

Introduction of measures which are accepted & practiced by farmers/farmers groups andsustainable; not sophisticated, low cost, use of available materials.

High priority to be given to sub-watersheds which are main contributors to the acute sedimentationproblems in the Wonogiri Reservoir.

Government support is still required & essential for supporting farming activities. The level ofincentives should be sufficiently high to induce farmers participation in soil conservation programs.

Precondition for success: strong & motivated extension services involving PPL & PKL will form thekey in implementing & sustaining conservation efforts.

1. Technical Issues

Grant aid in terrace rehabilitation has resulted in a detrimental change in social behavior in selfreliant activities for soil conservation and terrace rehabilitation.

Report on the Evaluation of Wonogiri Watershed Management, Watershed Management Technology Center(BP2TP DAS), Surakarta, 1995

Depending solely on conservation measures would mean implementing remedial measures withouttackling, preventing and solving the real causes.

2. Project Management Issues

Land is often left by the family head working on a seasonal basis in the cities. Recommendedagricultural measures are to be in line with this reality.

To achieve a balance between the farmers aspiration & the project objectives, an integrated planningwhich involves the bottom-up and bottom-down approaches is needed.Peoples behavior depends on their local culture. So, whatever programs must be formulatedaccordingly and not given as a uniform package for all locations, but must be arranged together withtheir leaders and then given to the people by various methods of extension and communications.Traditional values must be taken into account to ensure participation of communities.

3. Social & Institutional Issues

Technical collaboration team & technical working team at kabupaten level and integratedinstitutions at kecamatan & village levels are to be established.

Institutionalization of integrated & synergetic efforts & activities toward watershed management inthe Wonogiri catchment area is to be envisaged.

Consulting Services for the Upper Solo (Wonogiri) Watershed Protection Project, Monitoring & EvaluationFinal Report, July 1991, BCEOM

Planning is to be based on prospects for sustainable income flow, farmers traditional customs ofcultivation, off-farm income, availability of credits & markets, existing social priorities.

Reasons not following integrated approaches; project expenditures are to be spread as much aspossible among villages and communities in the project area.

Combined package of conservation measures and improved agricultural practices must provideadequate and immediate & long term financial gains to farmers for ensuring positive participation of

Agro-forestry approaches: Past projects were too much forestry oriented; to employ integratedforestry & agronomic approaches.

Source: JICA Study Team

Long-term ability of theWonogiri reservoir functionwill be secured for 100 years.

1)Decreasing ration of theeffective storage volume in thereservoir

2) Water supply to the Wonogiriirrigation area

Reservoirsedimentationsurvey andmonitoring ofwater supply

There will be no drastic change inreservoir management policy ofGovernment of Indonesia

1) The existing intake structurewill be completely reloevedfrom the sediment and garbageinflow from the Keduang River.

2) Majority of sediment andgarbage from the KeduangRiver will released from thenew gates to the vdownstreamreach from the dam.

1) Sediment deposition level atthe intake (every 2 month)

2) Frequency of interruption ofpower generation and watersupply

3) Volume of released sedimentfrom the new gates

1) Echo soundingsurvey at theintake

2) Operationrecord of powergeneration andwater supply

1) PJT I Bengawan Solo will operate thesediment storage reservoir according tothe new operation rule.

2) PJT I Bengawan Solo will conductsedimentation survey at the intakeperiodically.

Janapnese side:Funding assistance for construction of the sedimentstorage reservoir with new gates

Indonesian side:Government administrationAllocation of proper O&M cost by PJT I BengawanSolo

Sediment storage reservoir withnew gates will be constructed inthe Wonogiri reservoir.

Construction of:1) Sediment stodrage reservoirwith new gates in the Wonogirireservoir,2) Closure and overflow dikes

Socialization of downstreamresidents (stakeholders) for theconstruction

1) The watershed condition does notchange drastically from the condition in2006.2) The demand of water supply from thereservoir does not change drastically.3) Water quality of the downstreamreach is not drastically deteriorated.

Construction cost does not increasedrastically.

Visible confirmation Surver recordProgress report,completion reportand evaluationreport of theconstruction stage

1) The sediment storage reservoir willbe operated according to the reservoiroperation rule and maintained properly.

2) Maintenance dredging at the intakewill be conducted periodically.
