B.       Contribution of the Project to Water Resources/Irrigation  Development 

Item

Description

1. Necessity of the project

Entering the 1990s the self-sufficiency of rice in Indonesia is facing a crisis.  Rice production is quite abnormal and irregular compared with the 1980s.  The average unit yield of rice stands stationary in the 1990s.  The expansion of irrigation area lost momentum in the 1990s, and the rice import resumed from 1994.  Under such situation, the Government has adopted a policy of food security and sustenance of self-sufficiency in rice production.

The crop intensity of paddy fields in Indonesia is as low as 119% that indicates a possibility to expand the harvested area and thereby to increase the rice production through the irrigation development.  In 1999, there was about 2.1 million ha of rain-fed paddy fields and 1.17 million ha of upland paddy fields in Indonesia, for which the irrigated agriculture can be efficiently introduced without major problems such as transmigration, large-scale land development, social infrastructures, etc.

In order to promote the food security and sustenance of self-sufficiency in rice production, the government is keen to implement the irrigation development being effective for rice production, quick yielding and cost effective

The primary objective of PTSL-II is to enhance rice production through water resources development such as irrigation projects or pond/dam projects, contributing to the self-sufficiency of rice in Indonesia.

2. Beneficiary Area

The socio-economic condition of the people in the project area is at the subsistence level due to the limited income from agricultural activities.  The basic development constraint is the lack of irrigation water.  The present land use is as shown below.

·            Rainfed paddy field: 2,167 ha

·            Upland: - ha

The Way Curup Irrigation Sub-project area is a downstream part of left main canal command of Way Curup Irrigation Project.  The right main canal command and the upstream of the left main canal command are irrigated from the project canal system.  However in the Way Curup Irrigation Sub-project area, the irrigation is not provided because of insufficient canal conditions.  The rehabilitation/ improvement of the existing irrigation and drainage facilities including tertiary system will be executed under PTSL-II. 

With the project implementation, the principal benefit of the project is as follows:

·            Increase of cropping intensity from 74% to 200%

·            Increase of unit yield of crop by changing from rainfed agricultural land to irrigated land

 

C.       Project Area 

1. Water resources

The irrigation water for Way Curup sub-project is taken from Kemuning Lake supplied through the existing left main canal.  Kemuning Lake supplies water to the right and left main canals.

The average discharge, the maximum, and the minimum (10 days basis) of Kemuning Lake are estimated to be 7.00 m3/sec, 8.31 m3/sec, and 5.73 m3/sec, respectively.  

The river discharge is sufficient for the whole Way Curup Irrigation area of 4,706 ha with a cropping pattern of paddy (100 %) in the rainy season and paddy (50%) + palawija (50%) in the dry season (total annual cropping intensity of 200%).  

2. Land use

The present land use is as shown below.

·            Irrigated paddy field: - ha

·            Rain-fed paddy field: 2,167 ha

 

Irrigation is not provided because of insufficient conditions of irrigation facilities.  Tertiary system once constructed is not used, and mostly is damaged.  The rehabilitation of the tertiary system for 2,167 ha is required.  

All the sub-project area is already the rainfed farmland, so there is no need of land development.  About 50 % of the Sub-project area are cultivated with paddy under rainfed condition. 

Major parts of the sub-project area are confronted with ill-drainage problems.  Therefore, drainage improvement is included in the scope of the project works. 

3. Institutional set-up

There is no water users association in the sub-project area because no irrigation water supply is made so far. 

 

4. Environmental issues

·            The construction work for Way Curup was completed in 1995 therefore no countermeasures for land acquisition are needed, except for the main canal rehabilitation work. 

·            The area in which the rehabilitation works are to be carried out is already rain-fed paddy field therefore the existing flora and fauna have been well adapted to the existing agricultural system.

·            There is no major negative environmental impact because there will be no major change in the appearance of landscape, no disturbance on natural habitats, and no loss on historical, cultural and religious sites.

On-farm System

 

 

(1) Rehabilitation of tertiary canal system

2,167 ha

 

After review of the as-built drawings and filed investigation, the following project works were increased from the original:

(1)       Improvement of Main Canal

The upstream part of the main canal in this sub-project area for about 2 km is under the insufficient condition therefore the water supply is not carried to the sub-project. The improvement works are additionally required.

(2)       Increase of Tertiary Canal Improvement Area

Due to insufficient O&M of tertiary canals, most of the tertiary canals are damaged. Therefore the tertiary canal improvement area is increased to 2,167 ha from the original improvement area of 1,500 ha.

(3)       Increase of secondary canal improvement

Based on the joint walkthrough with the beneficiary farmers, the project office staff and the Consultant, the improvement of secondary canal was increased to 26.5 km from the original improvement of 3 km.

 

E.       Implementation Schedule

The implementation schedule of the project is presented as follows:

 

 

(1)   The civil work of the main irrigation and drainage systems will commence in July 2004 and be completed in December 2006 for a construction period of 30 months.

(2)   The civil work of the tertiary system will commence in March 2005 and be completed in October 2006 for a construction period of 20 months.
